Abstract

The invention discloses a tire safety detection system, and belongs to the field of automotive safety systems. The tire safety detection system comprises a wireless network sensor node and a network coordinator; the wireless network sensor node comprises an auxiliary microcontroller, a plurality of sensors and a radio frequency transmitter, wherein the sensors are connected with the auxiliary microcontroller, and the auxiliary microcontroller is connected with the radio frequency transmitter; the network coordinator comprises a main microcontroller, a bus interface module, a voice output module, a liquid-crystal display module and a radio frequency receiver, wherein the bus interface module, the voice output module and the liquid-crystal display module are respectively connected with the main microcontroller, and the main microcontroller is connected with the radio frequency receiver. According to the invention, the tire safety detection system uses a wireless communication technology, so that the cost and the power consumption of the system are greatly reduced, and the functions of monitoring the tire internal state in real time and carrying out abnormity alarming are realized.

Description

Technical field [0001] The invention relates to the field of automobile safety systems, in particular to a tire safety detection system. Background technique [0002] During the driving of the car, monitoring the tire pressure changes at any time is an essential function of the car safety system. [0003] At present, the tire pressure monitoring system (TPMS—Tire Pressure Monitoring System) is divided into a direct system and an indirect system. The indirect system uses ABS to determine tire pressure changes, and the system calibration is complicated. The direct system uses pressure and temperature sensors in each tire, and installs a wireless transmitter to send information such as pressure and temperature from the inside of the tire to the central receiving module. Although the cost of the direct system is slightly higher, it can measure the actual temperature and instantaneous pressure inside each tire at any time, determine the fault, and issue an alarm in real time, effectiv...
