What is TPMS (Tire Pressure Monitoring System) System[Copy link]
TPMS is the abbreviation of "Tire Pressure Monitoring System". It is mainly used to automatically monitor the tire pressure in real time when the car is driving, and to alarm for tire leakage and low pressure to ensure driving safety. In 2000, this concept frequently appeared in various newspapers and magazines, becoming a hot topic in the automotive industry. During the high-speed driving of the car, tire failure is the most worrying and difficult to prevent for all drivers, and it is also an important cause of sudden traffic accidents. According to statistics, 70% of traffic accidents on highways in China are caused by tire blowouts, while in the United States this proportion is as high as 80%. How to prevent tire blowouts has become an important issue for safe driving. According to the analysis of experts from the National Rubber Tire Quality Supervision Center, maintaining standard tire pressure and timely detecting tire leakage are the keys to preventing tire blowouts. And TPMS - Automobile Tire Pressure Monitoring System will undoubtedly be an ideal tool. Last year, due to the quality problems of Firestone tires, more than 100 people died and 400 people were injured. This matter attracted great attention from the industry and the US government. Bridgestone/Firestone was forced to recall 6.5 million tires in August last year. According to a recent survey by the American Society of Automotive Engineers, 260,000 traffic accidents in the United States are caused by low tire pressure or leakage each year. In addition, 75% of tire failures each year are caused by tire leakage or insufficient inflation. Due to the huge economic losses caused each year, the US government requires automakers to accelerate the development of TPMS systems in order to reduce the occurrence of tire accidents. On November 1, 2000, US President Clinton signed and approved the proposal of Congress to amend the Federal Transportation Act, requiring that all new cars after 2003 must have this system as a standard configuration. In July 2001, in response to the US Congress's requirement for vehicle installation of TPMS legislation, the US Department of Transportation and the National Highway Traffic Safety Administration jointly evaluated the two existing TPMS systems, and the report used TPMS as a special term for the first time. At present, TPMS is mainly divided into two types. One is Wheel-Speed Based TPMS (abbreviated as: WSB TPMS, or indirect TPMS). This system uses the wheel speed sensor of the car ABS system to compare the speed difference between tires to achieve the purpose of monitoring tire pressure. The main disadvantage of this type of system is that it cannot judge the situation of more than two tires being deflated at the same time and the speed exceeding 100 kilometers per hour. The other is Pressure-Sensor Based TPMS (abbreviated as: PSB TPMS, or direct TPMS). This system uses the pressure sensor installed in each tire to directly measure the tire pressure, and displays and monitors the tire pressure. When the tire pressure is too low or there is leakage, the system will automatically alarm. The report believes that PSB TPMS is superior to WSB TPMS in terms of function and performance. In the new car introductions this year, many European car manufacturers also installed PSB TPMS in their models, including the German BMW Z8, the French Citroen C5, the British Aston Martin super sports car Vanquish, the Lincoln Continental, the Pontiac flagship Bonneville SE, etc. The latest improvement of the Mercedes-Benz S-Class sedan also uses TPMS as an optional part; in addition, the Chrysler and Dodge minivans and the Chrysler 300M and Concorde Limited buses launched in the summer of 2002 are also equipped with TPMS. Most domestic car manufacturers have not yet conducted research in this area. After China joins the WTO, with the requirements of internationalization, it is believed that domestic manufacturers will keep up with this pace. With the continuous development of China's economy, more and more cars are entering ordinary families. According to authoritative sources, China will soon enter a period of rapid growth in family cars. In addition, China currently has more than 50 million cars, which will form a huge automotive consumer product market. In response to this situation, Langjie Electronic Technology Co., Ltd. took the lead in launching the brand-new product of automobile tire pressure monitor to the Chinese market. Langjie Electronic Technology Co., Ltd. is a joint venture between Foshan Taijie Electronic Co., Ltd. and MULTI-TECH INTERNATIONAL HOLDINGS LIMITED. The Taijie brand TPMS system is a Pressure-Sensor Based system. It is technically supported by Better Microsystems, Inc. of the United States and keeps pace with the latest American technology. It has North American and Chinese patents, is made of imported high-precision materials, and is exclusively produced in China. The system consists of a radio frequency transmitter with an air pressure sensor and a receiving monitor that can display the air pressure value installed on each tire. Langjie has currently developed a built-in system that can meet the integration requirements of automobile manufacturers. At the same time, Langjie can provide the required supporting solutions and related technical support for different models of various automobile manufacturers. In addition, Langjie will complete the development of a TPMS system for up to 10 tires in the first half of 2002.
TPMS has been around for several years and is used in many cars in the domestic market. As far as I know, many TPMS have batteries that cannot withstand the test and can only last for more than a year. Once TPMS is installed, it is very difficult to replace the battery.
