Problems solved by technology

The tire pressure monitoring system is mainly divided into indirect type and direct type. At present, some users adopt the indirect type tire pressure monitoring system, mainly through the wheel speed sensor of the automobile ABS system to compare the speed difference between the tires, so as to achieve the purpose of monitoring tire pressure. However, the indirect tire pressure monitoring system has low measurement accuracy, and in some cases such systems cannot work normally and consume a lot of power

Abstract

The invention relates to a tire pressure monitoring system using a direct measurement method. The tire pressure monitoring system comprises four measurement modules and a display module, wherein each the measurement module comprises a pressure sensor, a temperature sensor, an acceleration sensor, a singlechip, a sending circuit and a power supply, the four measurement modules are respectively mounted on inflating valves of four automobile tires, and the sending circuit comprises a sending chip and an antenna; the display module comprises a touch displayer, the singlechip, a wireless receiving circuit and the power supply, and the display module is mounted in an automobile cab; the four measurement modules communicate with the display module in a radio frequency manner. The measurement modules of the tire pressure monitoring system provided by the invention are high in precision and reliability and low in power consumption in the operational process, and can run steadily for a long time; moreover, a touch display screen can be used as a man-machine interaction interface, and thus, users are helped to set parameters, check monitoring data and synchronously monitor pressure and temperature of tires.

Description

technical field [0001] The invention relates to a tire pressure monitoring system, which belongs to the technical field of detection. Background technique [0002] Since human civilization entered the industrial age, automobiles have gradually become the most important means of transportation in the world. How to ensure driving safety has always been the focus of attention. During the high-speed driving of a car, tire failure is the most worrying and difficult to prevent for all drivers, and it is also one of the important reasons for sudden and vicious traffic accidents. According to statistics, 70% of traffic accidents on expressways in China are caused by blown tires, while in the United States this proportion is as high as 80%. Traffic accidents caused by low or high tire pressure account for 10% of the total. %. 85% of the pressure drop is the process of "slow puncture", and 95% of the tire blowout is because the tire is overloaded under the condition of insufficient ...
