Monitoring method and device of vehicle tyre data

Abstract

A vehicle tire data monitoring method and a monitoring device thereof relate to the technical field of wireless sensing and monitoring. The monitoring device comprises a tire monitoring module and a central module; the tire monitoring module is arranged in the tire; the central module is arranged in the vehicle; the tire monitoring module comprises sensors which comprise a pressure sensor, an acceleration sensor and a temperature sensor, a 8-bit RISC which centralizes the various data collected by the sensors and transmits the data to a RF emission module, the RF emission module and a TPMS special battery; the central module comprises a power management module which provides the central module with power for long time working, an EEPROM module, a RF receiving module, an SCM used for processing the data collected by the RF receiving module, a display module, a keyboard, an alarm module and a serial port communication module. The vehicle tire data monitoring method and a monitoring device thereof achieve to know the situation of the tire at any time, reinforce the safety of the vehicle during the running process and avoid a traffic accident from happening.

Description

technical field [0001] The present invention relates to the technical field of wireless sensor monitoring, and in particular to a new type of automobile tire pressure monitoring system, which mainly realizes the automatic monitoring of parameters such as the real-time air pressure and temperature of automobile tires, and once an abnormal situation occurs in the tire, an alarm is immediately notified to notify the driver . Background technique [0002] According to statistics, 70% to 80% of traffic accidents on expressways are caused by tire blowouts. How to prevent tire blowouts has become an important issue for safe driving. According to the analysis of relevant experts, maintaining the standard tire pressure for driving and finding the tire leak in time are the key to preventing tire blowout, and TPMS will undoubtedly be an ideal tool. TPMS is the English abbreviation of "Tire Pressure Monitoring System", which is mainly used for real-time automatic monitoring of tire pre...

Problems solved by technology

[0003] At present, TPMS is mainly divided into two types: one is based on wheel speed TPMS (WSB TPMS, indirect TPMS), this system uses the wheel speed sensor of the automobile ABS system to compare the speed difference between tires to achieve The purpose of monitoring tires, the main disadvantage of this type of system is that it cannot judge the situation of two or more tires being out of air at the same time and the situation of speed exceeding 100km per hour; the other is TPMS based on pressure sensor (PSB TPMS, 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 high or too low, the system will automatically alarm
