Recently, the hottest topic in the automobile circle, in addition to new cars such as Xiaomi Yuqi and Zunjie S800 landing in the Ministry of Industry and Information Technology, will be the OBD annual inspection.

President with a search, what?"The strictest in history", "The nightmare of car owners" and "People have hospitals and cars have M stops"Such statements emerge in endlessly:

On the short video platform, there are also some"The car is so new that OBD failed the annual inspection."Content of:

Public opinion is fierce, and many car owners can’t help wondering if their cars will be stuck because of OBD after reading these articles or videos.Faced with the need to go to the designated maintenance station to spend high-priced maintenance, or the vehicle is forced to scrap.

For a time, the condemnation of OBD annual inspection was wave after wave.

Then, the voice on the network is complicated. Who is telling the truth? Is the OBD annual inspection really so terrible, will it make the old car scrapped and the new car tremble?

This matter, we have to start with OBD.

so-calledOBD, is the abbreviation of "On-Board Diagnostics", which translates as "On-board diagnosis system”。

As long as your car is not too old, there is such an interface at the lower left of the steering wheel, and you can plug in a special OBD readerReading sensor data of the vehicle,You can also seeFault code of vehicle:

Similar to the application of other electronic and electrical technologies in automobiles, with more and more engine sensors, OBD has been loading cars overseas since 1970s and 1980s. After 2000, OBD has gradually become a standard in China.

At first, the role of OBD was only used to diagnose engine failure, which was convenient for car companies and repair shops to "prescribe the right medicine" after sale.

But later, with the deepening of environmental protection concept,Laws and policies are increasingly controlling the pollution of automobile exhaust.Forced car companies to upgrade engine technology to control vehicle exhaust emissions.

At this time, OBD, which can monitor the performance of three-way catalyst, oxygen sensor data, exhaust gas recirculation system (EGR), particle trap (GPF) and other components, can come in handy.

Theoretically, the most direct way to monitor automobile exhaust is to keep watch on the exhaust port.

This "dynamic vehicle exhaust detection method" has also become the root of many people’s "violent annual inspection": in the previous annual inspection, it was really necessary to push the car onto the platform and simulate the driving state.Test the exhaust emission by stepping on the accelerator!

But now, with the development of technology, the work of monitoring exhaust gas can be advanced to OBD. You only need to read the OBD in advance and monitor the running status of the engine.Judging the emission of tail gas:

For example, the EPF (particle trap) is blocked and the engine is lit; Or the three-way catalytic converter is dismantled, and harmful substances such as nitrogen oxides in the exhaust gas exceed the standard, which is definitely not going to pass the annual inspection.

In short, OBD, as a software system, mainly aims atSimplify the annual inspection process.

In fact, it is not a recent thing that OBD has been included in the annual inspection of automobiles, but it has been several years.

In 2019, the Ministry of Ecology and Environment issued the "Emission Limits and Measurement Methods of Gasoline Vehicle Pollutants (Double Idle Speed Method and Simple Working Condition Method)", which added OBD inspection as a part of "environmental inspection": focusing on key points,Environmental inspection.

Therefore, for example, if your tire pressure is too low, the vehicle will report to the police, or if the reversing image is broken, it will not get stuck and fail the annual inspection. have onlyEnvironmental protection and exhaust-related failures have occurred,You need to call back for maintenance and re-inspection.

So, why did the topic of OBD suddenly become so popular until recently?

Since the beginning of this year, many private testing stations have taken the risk of breaking the law and committing crimes in order to attract customers.Issue false emission inspection reports,Let the vehicles with substandard exhaust gas pass the annual inspection. The fee charged may be only a few hundred yuan.

Perhaps it was reported by an informant, or maybe the relevant department seized relevant clues, but it is more likely that the environmental protection department monitored it.The air pollution caused by automobile exhaust is becoming more and more serious …After Dalian seized the first related case in early November, many inspection stations were investigated and punished by fines, suspension of inspection and rectification.

This is a lot of human feelings recently."The annual inspection of automobiles has become stricter"The reason-

In the past, the monitoring station turned a blind eye, and the testing fee was safe. If you don’t strictly test now, you really want to close down for rectification, and you have no money to earn!

It is precisely because of this that many old cars in poor condition, especially those trucks with illness, have become the targets of "not passing the annual inspection" and "being the most injured" in this round.

Old netizens also know that this topic that affects people’s livelihood has always been a stimulant for the media. This has led to a lot of unscrupulous self-media catching shadows and selling anxiety.Get a huge amount of traffic by causing panic.

So what?"OBD annual inspection is a new regulation in 2025", "OBD annual inspection for three times but the car is scrapped",It’s all for this dish of vinegar, jiaozi,It’s a pure rumor.

Then the more critical question is coming, "in the rumor"M station"What is it? Can the owners of unqualified vehicles only go to M station for maintenance or take the vehicle scrapping process?

In fact, in the "Methods" issued by the Ministry of Ecology and Environment, the relevant regulations on OBD detectionThere is no saying that "unqualified products can only be sent to M station for maintenance", and there is no saying that "X times of unqualified products need to be scrapped".

This so-called M station comes from the Notice on Establishing and Implementing the Vehicle Emission Inspection and Maintenance System jointly issued by the Ministry of Ecology and Environment, the Ministry of Transport and the General Administration of Market Supervision in 2020, and it corresponds to Station I..

The official explanation of the Bureau of Ecology and EnvironmentHere’s the thing:

I/M system is a system that motor vehicles in use should be inspected regularly by the motor vehicle emission inspection agency (Station I) in accordance with the relevant regulations of the state and our province, and vehicles with unqualified exhaust emissions must be repaired by qualified maintenance enterprises (Station M), so as to finally improve the pollutant emission status of motor vehicles. "I station" refers to the automobile emission inspection agency, which is what we usually call the motor vehicle inspection station; "M station" refers to the maintenance (repair) organization of automobile emission performance, which is what we usually call a repair shop, but it must have certain qualifications.

"Local transportation departments at all levels should supervise and guide the maintenance and repair of automobile emissions according to laws and regulations.One or two types of automobile maintenance enterprises and three types of automobile maintenance enterprises engaged in engine maintenance can be used as automobile emission performance maintenance (maintenance) stations.. "

Therefore, this M station is not a few official cooperative stations, but a group of maintenance stations with formal maintenance qualifications and will not be "corroded by money", which can ensure thatVehicles are inspected annually without cheating.

To put it bluntly, you can go anywhere to repair the car; It’s just that I have to go back to M station in the end to make sure I didn’t cheat.

As for everyone who thinks that the M station is expensive, and the exhaust gas may not meet the standard after repair, there is actually a poor information, which is hard to believe outside the automobile industry:These accessories related to exhaust gas are really expensive! ! !

Take a luxury brand as an example, just an oxygen sensor,Official price 3200:

If it is a three-way catalytic converter meeting the emission of country 6b,Official price 39899.99(There are odd and whole ones.）：

Moreover, even if one or more original parts are replaced at a huge cost, it may be due to various reasons such as "burning engine oil", "carbon accumulation in the cylinder", "insufficient combustion of gasoline" and "GPF regeneration".Causing the tail gas not to pass.

(President tips: Those car owners who can’t pass the annual inspection and want to keep their own vehicles can actually try to start from these angles, or directly drive on the high-speed Bigfoot oil for a while, instead of blindly replacing accessories at high prices.

In addition, the electronic sensor can be repaired by auxiliary factory parts, but if it is a ternary accessory, the auxiliary factory parts are almost all money-wasting, and it is likely that it will not pass if it is changed.)

This means that according to the relevant documentsExcessive emission vehicleThis passage:

"In the use of motor vehicles to discharge air pollutants exceeding the standard, it should be maintained; After maintenance or adoption of pollution control technology, if the emission of air pollutants still does not meet the national emission standards for motor vehicles in use, it should be forcibly scrapped. "

Because of this, many people "feel tired and don’t love" and choose to scrap their cars and throw them into the arms of new cars.

Write it at the end

Finally, the president also wants to say a few fair words impartially.

Whether the OBD test is included in the annual inspection of automobiles or the state establishes and implements the automobile emission inspection and maintenance system, it is actually a good thing.

The former canPrevention and control of air pollution,NengHelp users understand the working state of the car;And the latter is to push the whole car.Standardization of annual inspection system,evenStandardization of new car productionA link in.

If it can be strictly enforced, those "broken cars" with black smoke and heavy tail gas will not appear on the road, affecting the health of pedestrians and non-motor vehicles; No more car companies will dare to "cut corners" on emissions.

Unfortunately, good intentions do not always bring good results.

In the process of the sustainable development of the automobile industry, it is not uncommon for emission inspection agencies and emission performance maintenance stations to play in collusion. This is the industrial chain relationship of "being both a referee and an athlete", and the account will be divided afterwards …

Therefore, some netizens shared their cars that were stuck in the OBD detection step.It’s not all lies.

For example, when a BMW X3 was inspected, the emission was up to standard, and there was no fault code, but the inspection agency’s machine did not read the OBD data, and the final result was the same.The vehicle was called back and asked for re-inspection.

From the user’s point of view, this is a bit like an "accident"-my car is fine, but I need to spend extra time to check it again. Isn’t this a waste of time, energy (and maybe money)?

Not to mention, there are also some cars that are in good condition, which makes the owners angry.

Although there is almost no need to worry about problems in the annual inspection of vehicles that are normally used, this does not affect the fear of responsibility of the nervous testing institutions. If there is a sign of trouble, they will protect themselves and stay away;

There is no guarantee that some normal vehicles will be stuck in the first annual inspection after 6 years because of the quality problems of the vehicles themselves.

But in any case, standardization is the only way for the domestic automobile industry.

This is true for fuel vehicles, and so is it for new energy vehicles.

Part of the rumor—The "New Regulations for 2025" refers to the "Inspection Rules for Safety Performance of New Energy Vehicles" which will be launched on March 1, 2025.

Little friends who want to know, poke here: "New Energy Exclusive Annual Inspection" is about to land! Will your electric car survive next year?

This is China’s first safety inspection standard specifically for new energy vehicles.Suitable for pure electric vehicles and plug-in hybrid vehicles (including extended range),The inspection of three electrical systems (battery, motor and electronic control) has been added.

This means that the annual inspection of new energy vehicles also has special inspection items, and the "three-electricity inspection (especially the health of power batteries)", which is strongly called by the public, is really available now.

Predictably,In the future, the testing standards for new energy vehicles will be gradually improved.Problems will always accompany.

But the president believes that the development of things is spiraling, and it is inevitable that there will be setbacks and contradictions. The end result must be that the whole industry will continue to improve.

　　Cctv newsToday, no matter whether you go out for shopping or dining, it is no longer strange to take out your mobile phone and "sweep it". However, after the full popularity of online payment, the payment risk has become the biggest security risk for mobile phone users. Especially some payment functions, users may not know.

　　No password, click and the money will be taken away!

　　At a fast-food restaurant in Tianjin, Mr. Zhang pointed his mobile phone at the cash register and only heard a "beep" to end the whole payment process. However, what makes Mr. Zhang slightly puzzled is that there is no need to enter the payment password when paying.

　　Ms. Sun reflected that when she used a debit card of China Bank to spend money, the payee completed the spending just like swiping a subway bus card, and did not need to enter a password.

　　There are media tests. No matter using the payment function of WeChat or Alipay or the bank card with the function of "flash payment", there is no need to enter the payment password when the consumption does not exceed a certain amount, and there is no confirmation link for the payment price. This is because your functions of "small secret exemption" and "flash payment" are turned on.

　　What are the functions of "small secret exemption" and "flash payment"?

　　According to industry insiders, such payments as "small secret-free" and "flash payment" mean that when the consumption amount is lower than the limited value, the user can complete the consumption without entering a password. At present, many people have opened and used the function of "small amount of confidentiality" when paying. Although the payment process is simple and convenient, it is also easy for consumers to be stolen without knowing it.

　　Searching for keywords on the Internet is not difficult to find that this "hidden danger" is not a case. Xiao Xu’s mobile phone was stolen from a hotel in a scenic spot in Hangzhou. Due to the secret-free function of WeChat micropayment, all the money in WeChat balance and bound bank card was stolen. Many people said, "It used to be the most troublesome to lose the phone book, but now I have to worry that the money connected to the phone may be gone."

　　The function is turned on by default, and the economic loss is borne by the individual.

　　According to the information of UnionPay, the issuing bank often sets the function of "small amount of confidentiality and visa exemption" together with "flash payment" as the default. When a cardholder conducts a transaction with a certain amount (RMB in 300 yuan, subject to the local limit overseas) or less, he only needs to put the bank card near the "flash payment" sensing area to complete the payment. In this process, the cardholder will not be asked to enter a password, and there is no need to sign.

　　According to the customer service staff of China Bank, this kind of "small-sum secret-free" service with the logo of "quickpass for Flash Payment" on the card surface is opened by default, and no password is required for payment, and each transaction cannot exceed 300 yuan, and each card is capped at 2,000 yuan per day. If there is a security risk, the customer needs to bring his ID card to the bank outlet to cancel the business.

　　In terms of mobile payment, Alipay’s "payment code" function is turned on by default, and its instructions state that it is not necessary to verify the payment password for every order less than or equal to 1000 yuan.

　　It is also stated in the WeChat payment user service agreement that when the payment code is used to pay the consumption less than 3,000 yuan in 1000 yuan (a specific merchant), there is no need to verify the transaction instructions such as passwords, and the economic losses caused by loss and other behaviors are borne by individuals.

　　Experts remind: security is the premise of convenient payment.

　　Users often don’t know when this payment function is turned on, which has certain security risks. Experts said that relevant institutions should effectively inform users when opening such functions, and don’t forget the safety red line while pursuing convenience.

　　 Cheng Hua, an associate professor at the School of Economics of Renmin University of China, said that at present, payment institutions have not done enough in popularizing basic knowledge and informing relevant information, and many consumers have actively or passively opened this service without clearly understanding the advantages and disadvantages of a certain function. The supervision of "small-sum confidential exemption" must be strengthened. For accounts with intensive confidential payment, the payment institution should set up an early warning or even tracking mechanism, or delay the transfer to avoid the loss of users’ property.

　　Cao Xingquan, a professor at the School of Civil and Commercial Law of Southwest University of Political Science and Law, believes that functional services such as "small-sum confidential payment" need to be set up with a prompt and delayed reading mechanism when they are opened. Relevant institutions or banks should solicit opinions from users when they are opened, and actively fulfill their obligation of explanation, and cannot simply open a function for users in the form of "default". As the last "safety line" of payment, passwords cannot be easily cancelled.

CCTV News:China Giant Panda Conservation Research Center is the largest, most comprehensive and highest-level giant panda conservation research institution in the world. In the past 10 years, it has not only made breakthroughs in overcoming artificial breeding of giant pandas, but also actively explored the wild release of artificially bred giant pandas and promoted the protection of wild giant pandas and their habitats.

　At Dujiangyan base of China Giant Panda Protection Research Center, the staff of Panda Hospital are conducting routine blood examination of giant pandas, which is of great significance to know the health status of giant pandas regularly. In addition to using advanced medical means to ensure the healthy growth of giant pandas, the Panda Center has made remarkable achievements in the field of wild release and introduction in the past 10 years.

Wei Rongping, Director of Wolong Shenshuping Base, China Giant Panda Protection Research Center:First of all, in the aspect of panda wild training and release, we have overcome the key technology of panda wild training and release, and we have innovatively adopted the technology of "mother animals with cubs", achieving a good result of successfully releasing 10 pandas and surviving 9 pandas.

Wei Rongping said that from 2017 to this year, six giant pandas in the Panda Center participated in the introduction work in the wild, and so far 10 cubs have been bred.

In the past 10 years, the Panda Center has also built the world’s largest and most extensive panda cooperation and exchange platform.

Wei Rongping, Director of Wolong Shenshuping Base, China Giant Panda Protection Research Center:By 2022, 18 zoos in 16 countries and regions have conducted international exchanges with us. By 2022, we have also bred 21 giant panda cubs overseas with international cooperation units.

In addition, in order to support the construction of the Giant Panda National Park and strengthen the protection of wild animals and plants, the Panda Center has also been approved to set up the Key Laboratory of Conservation Biology of Rare Animals in the Giant Panda National Park and the National Long-term Research Base of Conservation Biology of Endangered Wild Animals, focusing on the rescue and disease prevention of wild giant pandas, rejuvenation of small populations in the wild and breeding of captive giant pandas.　

What I want to introduce to you today is. The strength of the car still needs to be understood before we know, so let’s take a look.

Let’s take a look at the appearance of Jetway X70 first. The front design of Jetway X70 is very young and fashionable. With the hexagonal mesh, it looks sporty. Coupled with the personalized headlights, the visual impact is full. The car is equipped with LED daytime running lights, delayed shutdown and so on. Coming to the side of the car body, the size of the car body is 4749 mm * 1900 mm * 1720 mm. The car adopts deep lines, and the car body presents an atmospheric design style, which is eye-catching with large-sized thick-walled tires. In the design of the rear end, the rear end looks very delicate, the taillights look very avant-garde, and with the unique exhaust pipe, the shape is more solid.

Coming into the car, the interior of Jetway X70 adopts a personalized shape, which meets the aesthetic standards of young people. The steering wheel of the car is very fashionable and made of imitation leather, showing a sense of atmosphere. From the central control point of view, the design of the center console is reasonable, which makes the interior design quite layered, which is in line with the temperament of the car. The dashboard and seats give people a good feeling, too. Let’s take a look. The car is equipped with a fashionable dashboard, and the trendy design elements make people remember it at a glance. The car uses a leather-like seat, and the seat is wrapped in place, which is very comfortable to ride.

The Jetway X70 is matched with a wet dual clutch (DCT) gearbox, with a maximum power of 115KW and a maximum torque of 230N.m, with good power performance.

The Jetway X70 trunk has high space availability and excellent loading capacity, and the rear seats support the proportion down, so the space can be further expanded. At the same time, the car is equipped with fatigue warning, anti-lock braking (ABS), LED daytime running lights, brake assist (EBA/BAS, etc.), braking force distribution (EBD) main driver airbag, co-pilot airbag and other safety configurations.

To sum up: SUV has an atmospheric appearance, good spatial performance and high cost performance. I wonder if you are interested in it.

Recently, the 3D model of the interior and exterior of the new Tesla was exposed, both inside and outside are basically the same as the new Tesla. It is understood that the new car is expected to be released in 2025.

According to the real shot of the interior, the gear configuration is cancelled, and the gear interface is integrated on the new screen for operation. At the same time, it is equipped with a push-button turn signal and a sliding touch shift operating mechanism, which makes the driving operation more convenient and intelligent. In addition, it is expected that the new car will add 256-color annular atmosphere lights on the basis of the new model, creating an encircling visual effect. The front area of the central armrest is decorated with imitation carbon fiber, which enhances the luxury and sports atmosphere inside the car.

In terms of appearance, according to spy photos and 3D models, the new Model Y adopts a design language similar to the new Model 3, and the front face has been adjusted to become more concise and neat. The headlight group has become more slender and adopted a narrow strip design, which enhances the fashion sense of the vehicle. Bumper lines have also become more concise, combined with slender headlights to create a more refreshing visual effect.

The waistline of the car body is basically consistent with the current model, maintaining the smooth lines and dynamic posture of Model Y.

The rear part of the car is equipped with an upturned duckling tail, which echoes the "C" taillight of the new Model 3, improving the recognition and sense of movement of the vehicle.

In terms of motivation, there is not much news yet. The new car is expected to be upgraded in suspension, performance and other parts.

Tesla Model Y is outstanding in the domestic medium-sized SUV market, and the new car has been upgraded greatly, so it is not a problem to continue this momentum.

First, preface: keep up with the watch Xiaomi brings a more professional and comprehensive new bracelet.

With the growth of modern people’s demand for exercise and health monitoring, the shape of smart bracelet is becoming more and more perfect. From the original only counting steps and monitoring sleep, to the current all-weather monitoring of motion recognition, blood oxygen and heart rate, it can be functionally aligned with watches.

I thought that mi band 7 Pro had surpassed the ceiling of graduation work, and it was difficult to make further breakthrough. But I didn’t expect that the mi band 8 Pro brought this time directly pierced the ceiling of the bracelet, which brought us different surprises.

After all, the development of the bracelet has been very comprehensive, and it is necessary to tap more functions of the bracelet and meet more usage scenarios for users, fearing that many brain cells of the siege lions will be burned.

Fast Technology has got this newly released mi band 8 Pro. Let’s see what’s unique about it.

Compared with the previous generation of mi band 7 Pro, mi band 8 Pro has brought a bigger screen and higher brightness, and at the same time, the professionalism in sports and health has also improved.

1. Larger screen and dual-channel monitoring module for the first time.

Mi band 8 Pro has increased the screen size to 1.74 inches and the brightness to 600nits. With larger size and higher brightness, you can clearly watch the contents displayed on the bracelet outdoors.

It also added a dual-channel sign sensor for the first time, which brought more accurate monitoring ability of heart rate, blood oxygen and heart rate.

It is much more friendly for users with tattoos, heavy hair and dark skin, because the accuracy of general watches is greatly reduced when they encounter such situations.

The dual-channel monitoring module brought this time can prevent signal loss and noise caused by loose fitting, and the monitoring effect is more accurate than that of single channel.

2. The sports function goes further, and entertainment majors coexist.

Fitness needs perseverance, and this process is rather boring. mi band 8 Pro has brought many entertainment improvements on the premise of maintaining professionalism.

In order to reduce the user’s mentality of giving up halfway, the mobile APP has added a somatosensory interactive course, which can be transformed into a somatosensory game with the bracelet, which is full of entertainment.

Pre-warm-up and stretching after exercise are essential. Non-standard warm-up actions will lead to muscle strain and inefficient exercise, soMi band 8 Pro will warm up 3D.drawBrought it to the bracelet, check whether your actions are standard at any time.

3. You can also use the Miaoxiang Center by joining the Mijia Ecological Bracelet.

With the improvement of each ecology, Mijia is not far behind, and the bracelet can also be used as a part of the ecology.

Mi band 8 Pro joined the Miaoxiang Center.It is not a problem to control the mobile phone, tablet, speaker, etc. through the bracelet, which completes the missing link of Mijia wearable equipment.

Next, let’s take a look at how easy it is to use the upgraded mi band 8 Pro.

Second, the appearance: the screen is bigger and brighter, and the dual-channel monitoring module is added for the first time.

Compared with the previous generation of mi band 7 Pro, the design changes are not too big, and they all adopt the shape of "small square screen", which brings visual effects with equal width on four sides.

The screen of this generation has reached 1.74 inches, the resolution has reached 480×336, the refresh rate is 60Hz, and the PPI has also been upgraded to 336.

Although the specifications have been improved to some extent, the size of the watch body is still very restrained, reaching 46×33.35×9.99, which is slightly thinner than the previous generation’s 11mm and weighs only 22.5g g.

The surface is covered with Corning glass, which makes the bracelet more scratch-resistant and tough, and it will not affect the display effect after long-term use.

The brightness of the bracelet has also been increased to 600nits. With the ambient light sensor, it can be seen clearly outdoors without being too bright indoors.

In operation, the whole table body has no physical buttons, and it maintains a full touch mode, and it can realize different operations such as returning, entering the home page, notifying, etc. only by sliding.

The middle frame is made of plastic material processed by NCVM technology, which ensures lightness, while the metal texture makes the bracelet look more classy.

The middle part is the heart rate sensor. It can be seen that there are two sensors in the upper part, which is the dual-channel monitoring module body. Generally, there is only one bracelet.

The two metal points at the bottom are used for magnetic charging. Just lean the charger gently and it will automatically adsorb, which is very convenient.

It is worth mentioning that the quick release button of the strap is internal, and the previous generation has a little difficulty in pressing the button. The pressure of this generation has become smaller, and it is easier to remove and replace the strap.

Third, sports: bracelets can also experience somatosensory games. 3D fitness animation is more intuitive.

When you first turn on the phone, you need to activate the watch with the mobile phone "Xiaomi Sports Health" APP, but in this process, the author found that there is a "somatosensory interactive course" on the sports page.

After starting the game, you will enter a somatosensory game similar to the game console.

From the experience, although it is not as accurate as the game console handle, the recognition rate of mi band 8 Pro in action is quite good.

This should be realized through the recognition of acceleration sensors and gyro sensors. These sensors can also record motion data in real time, such as steps, walking distance, calorie consumption and so on.

After completing the game, the mobile phone interface will give the training results, and it can be seen that the author has not moved at all, so the hit rate is 0%.

This also shows that it is impossible to be lazy, and the sensor will record the user’s actions in real time to determine whether it is effective.

This somatosensory interactive course is based on boxing courses, and you can master skills such as straight boxing, swing boxing, hook boxing, pace and hiding during play.

In addition to boxing, the game can also choose ninja-style chopping, darts and other games, users can choose according to their own interests.

You can even project the screen of your mobile phone on the TV, and then cooperate with mi band 8 Pro to realize the motion somatosensory function of the game console at low cost.

In sports, mi band 8 Pro also brings wrist running courses, which can teach you from the beginning. Each course can bring more scientific and intuitive running guidance to users, and avoid stepping on the pit when Xiaobai gets started.

Every time you exercise, it is essential to warm up in the early stage and stretch after exercise, which can promote cardiopulmonary function, reduce exercise loss and let users enter the state quickly.

Mi band 8 Pro brings 3D exercise and fitness animation, which can be viewed on the bracelet without a mobile phone, and can provide more scientific and intuitive exercise guidance.

From the screen reading habits, animation is more intuitive than text, which actually maximizes the use of the bracelet AMOLED screen.

Mi band 8 Pro retains the five-star positioning of Beidou, GPS, GLONASS, Galileo and QZSS, which can record the route in real time during the movement and accurately record the movement trajectory even if it is separated from the mobile phone.

It should be noted that, because it does not depend on the mobile phone, the bracelet needs to be positioned in an outdoor open place, and there should be no obstructions on the top of the head, otherwise the positioning effect will be affected, and the battery life of the bracelet will be reduced to some extent after the positioning is turned on.

During exercise, information such as speed and heart rate can be displayed on the bracelet. If you want to view detailed data such as maps, you need the "Xiaomi Sports Health" APP on your mobile phone to cooperate.

Fourth, health monitoring and wonderful enjoyment center: Mijia ecology is more complete, and bracelets can also control smart homes.

-health monitoring

After mi band 8 Pro joined the dual-channel monitoring module, it is more accurate to monitor data such as sleep, heart rate and blood oxygen saturation.

It also brought a nap detection that was not available in the past, so that even a nap can be accurately recorded.

Just like during a nap, mi band 8 Pro accurately recorded the duration of the author’s lunch break, but because it was a sporadic nap, there was no data such as deep sleep, shallow sleep and eye movement, only night sleep was supported.

Mi band 8 Pro supports all-weather monitoring of heart rate, blood oxygen, stress and other health conditions, but only the data of the day can be viewed. If you want to view more detailed data recorded in the past, you need to cooperate with the "Xiaomi Sports Health" APP on your mobile phone.

-wonderful enjoyment center

Mi band 8 Pro has also joined a part of Xiaomi’s ecology. Through the wonderful enjoyment center, you can control the TV, speakers, mobile phones, tablets and other devices at home, and use them as wrist remote controllers. Common song cutting and volume control can be done, and you can also project the sports data on the bracelet onto the TV during sports.

V. Summary: The best choice to maintain the status of the bracelet ceiling at 399 yuan in the same gear.

As the most important part of wearable devices, mi band 8 Pro has improved its functions on the original basis, further explored new ways of playing watches, and brought a more versatile use experience.

On the basis of the original functions of motion recognition, five-star satellite positioning and all-weather monitoring, this paper introduces some very practical functions, such as somatosensory interactive course and 3D fitness animation. These functions are essentially to lower the threshold for users to get started, stimulate the passion of sports, and find and enjoy the fun of fitness in the boring exercise process.

After all, for such wearable devices, it is not easy to ensure professionalism while taking into account entertainment and practicality on such a small bracelet.

It is the first time to join the dual-channel dual-channel monitoring module, which brings more accurate and professional health monitoring effect, so that users can know their own health status in time and intervene, so as to be aware of it.

There is also the wonderful enjoyment center of mi band 8 Pro, which makes up the missing wearable device in the Mijia ecology, and can control smart homes such as speakers and air conditioners through bracelets, which can be regarded as satisfying the thoughts of rice noodles.

Mi band 8 Pro has brought so many upgrades, and its size has been made thinner. It has not sacrificed its battery life.
