Tire pressure monitoring method based on wireless sensor

Abstract

The invention provides a tire pressure monitoring method based on a wireless sensor. The method comprises the following steps that a tire pressure sensor module collects tire pressure information in a vehicle and sends the tire pressure information to a WSN (Wireless Sensor Network) coordinator through a router; and after the tire pressure sensor module receives a wake-up command of the WSN coordinator, the tire pressure sensor module detects receiving data immediately, stores measured values after collection, encapsulates the data and sends the data to a monitoring chief platform through the WSN coordinator. According to the tire pressure monitoring method based on the wireless sensor, which is provided by the invention, the reliability and the real-time performance of the data in a wireless transmission process are enhanced, the node power consumption is reduced, the network lifetime is prolonged, and the reliable wireless data transmission is finally realized under the complicated electromagnetic environment in the vehicle.

Description

technical field [0001] The invention relates to information sensing and collection, in particular to a tire pressure monitoring method based on a wireless sensor. Background technique [0002] In recent years, my country's motor vehicle consumption demand has been strong, the process of motorization has been accelerating, and the annual production and ownership of domestic motor vehicles have continued to grow rapidly. Users have higher and higher requirements on the performance of motor vehicles, followed by the continuous improvement of related detection technologies for motor vehicles. At present, there are two methods for motor vehicle performance testing. One is the standard motor vehicle testing line for routine vehicle performance testing and safety testing, which requires a larger testing space and more testing equipment. The other is a portable on-board test equipment used for vehicle road testing that directly reflects the real-time conditions of the vehicle durin...
