The function of tire pressure alarm and the difference from tire pressure monitoring

With the rapid development of the automotive industry, more and more novel and high-tech configurations are added to new cars, and people will be dazzled by these newly added configurations when buying a car. For many young car buyers, safety configuration is now becoming more and more important. Among them, tire pressure monitoring is a new feature that many people pay attention to when buying a car. This function is actually a more important part of the safety configuration, but It has not been taken seriously for a long time before. As people's awareness of safe travel has increased, the existence of tire pressure monitoring has gradually been recognized and valued by everyone. However, many people often see the two names of tire pressure monitoring and tire pressure alarm when buying a car. What is the difference between them? Let's take a look today

First look at tire pressure monitoring. It mainly includes direct tire pressure monitoring and indirect tire pressure monitoring. Specifically, the pressure sensor installed in each tire is used to directly measure the tire pressure. At the same time, the specific tire pressure is measured through a wireless transmitter. The tire pressure information is transmitted from the inside of the tire to the central module, and then we can see the tire pressure information of each tire on the display in the car.

The cost of the indirect tire pressure detection device is much lower than that of the direct one. It uses the sensor on the car's ABS brake system to compare the number of rotations of the four tires. If the tire pressure of one of the tires is relatively low, then its rotation The frequency will be different from other tires, and then the in-car computer will be used to adjust the software, and the driver will be warned that one of the tires will be lower than the other three. In this way, there are quite a few problems with the indirect tire pressure monitoring device. The first is that it cannot tell the driver which tire has a lower tire pressure. Secondly, if the tire pressure of 4 tires is reduced at the same time, then there is no way for this device to give an alarm, which is equivalent to losing its effect.

This situation is more common in winter, especially when the car is cornering. The number of rotations of the outer tires is usually greater than the number of rotations of the inner tires. Therefore, indirect tire pressure detection devices generally cannot accurately analyze this situation. Cause the function to fail.

The tire pressure alarm, as the name implies, is to send out an alarm when the tire pressure is insufficient or too high to warn the driver to pay attention to the condition of the tire. This device only has the function of issuing an alarm, and there is no way to specifically display the information of each tire. , So compared with tire pressure monitoring, its functionality is significantly lower.

For many young car buyers, when they first bought a car, they pursued the tire pressure monitoring configuration, but after they got it, they only found that their car only had a tire pressure alarm. Although it looks like only two words, The functions between them are very different. Among them, when many car owners buy some models, the configuration before the purchase is marked with tire pressure monitoring, but after getting them, they find that the car dashboard will only display whether the tires are normal or not, but can not display specific numerical information. This situation can actually be regarded as an act of a manufacturer's allocation reduction. If it is discovered, you should communicate with the manufacturer or report this situation in a timely manner.

At the same time, I still recommend that you try to equip the tire pressure monitoring configuration when you buy a car because this function has many benefits, it can prevent accidents, and promptly report to the police when the tires show signs of danger to avoid seriousness. The occurrence of the accident. Secondly, it can extend the life of the tire. At the same time, the tire pressure detection function can also help us improve fuel economy during daily driving because when the air pressure in the tire is too low, it will increase frictional resistance and fuel consumption. , So once the tire pressure monitoring tells you that the air pressure in the tire is insufficient, you can make timely countermeasures to reduce unnecessary losses.

When the tire is flat, the vehicle will run off the track. At high speeds, the front wheel will leak and blow out will cause personal hazards, and the rear wheel will blow out and the vehicle will shake seriously. Real-time monitoring of car tire pressure, installing a tire pressure monitoring alarm on the car can prevent accidents caused by abnormal car tire pressure.

According to statistics, 70% of highway accidents are caused by tire problems, and 80% are caused by abnormal tire pressure and temperature. Real-time monitoring of tire pressure and temperature can prevent problems before they occur. Each tire is equipped with a high-sensitivity sensor transmitter to monitor the tire pressure and temperature in real-time, and the data signal is wirelessly transmitted to the terminal receiving system in the car. When tires leak, tire pressure is too high or too low, the temperature is too high and in other abnormal conditions, the terminal will automatically alarm and display the tire status to ensure the safety of the car.

There are many brands of tire pressure monitoring alarms on the market. According to the various tire pressure monitoring alarms launched by the domestic automobile safety electronics company General Tie, the current tire pressure monitoring alarms on the market can be summarized as navigation/DVD upgrade type and cigarette lighter type. , Portable, free-standing, ceiling-mounted, external, etc. Among them, the external tpms can establish a connection with the mobile phone through the receiver to send and receive Bluetooth signals, and display tire pressure data.
