Multi-sensor communication method used for tire pressure detection

Abstract

The invention provides a multi-sensor communication method used for tire pressure detection. The multi-sensor communication method includes the following steps that pressure sensors in four tires of an automobile are marked, a front left wheel is marked to be A, a front right wheel is marked to be B, a rear left wheel is marked to be C, and a rear right wheel is marked to be D; a wireless communication module is used for giving out commands without identify characteristics to the pressure sensors of the tire A, the tire B, the tire C and the tire D; and after the pressure sensor A, the pressure sensor B, the pressure sensor C and the pressure sensor D receive the commands without the identify characteristics, setting of time delay data is conducted according to characteristics of the pressure sensor A, the pressure sensor B, the pressure sensor C and the pressure sensor D, the time delay data are marked to be a, b, c and d correspondingly; and the time delay data set for pressure sensor A, the pressure sensor B, the pressure sensor C and the pressure sensor D are compared, when the condition of a>b>c>d is met, determining of the time delay data is conducted respectively, and when the condition of a>b>c>d is not met, the third step is conducted, and setting of the time delay data is conducted again.

Description

technical field [0001] The invention relates to a multi-sensor communication method for tire pressure detection, which belongs to the technical field of tire pressure detection. Background technique [0002] With the progress of the industrial economy, automobiles have begun to be used in large quantities. During the use of automobiles, traffic accidents may be caused due to low tire pressure or leakage, and 70% of traffic accidents on expressways are caused by punctures; The tire pressure monitoring system is a wireless transmission technology, which uses a high-sensitivity miniature wireless sensor device fixed in the car tire to collect data such as car tire pressure and temperature when driving or stationary, and transmits the data to the cab. In the host computer, relevant data such as tire pressure and temperature are displayed in digital form in real time, and when the tire is abnormal, it will remind the driver to give an early warning in the form of buzzer or voice,...

[0002] With the progress of the industrial economy, automobiles have begun to be used in large quantities. During the use of automobiles, traffic accidents may be caused due to low tire pressure or leakage, and 70% of traffic accidents on expressways are caused by punctures; The tire pressure monitoring system is a wireless transmission technology, which uses a high-sensitivity miniature wireless sensor device fixed in the car tire to collect data such as car tire pressure and temperature when driving or stationary, and transmits the data to the cab. In the host computer, relevant data such as tire pressure and temperature are displayed in digital form in real time, and when the tire is abnormal, it will remind the driver to give an early warning in the form of buzzer or voice, so as to ensure that the pressure and temperature of the tire are maintained. Within the standard range, it can reduce the probability of puncture and tire damage, reduce fuel consumption and damage to vehicle components; in the prior art, there are multiple sensors that interfere with each other during the communication process with the tire pressure detection device, which is not conducive to the tire pressure of the car. Stable and accurate communication, which leads to the inability to perform good communication when performing automobile tire pressure detection, which is very inconvenient to use, and will cause great safety hazards to people's driving, and cannot better meet people's needs, so There is a need for a multi-sensor communication method for tire pressure detection
