Temperature and air pressure monitoring system of car tire based on wireless technology of ZigBee

Abstract

The invention discloses a temperature and air pressure monitoring system of a car tire based on the wireless technology of ZigBee. According to incomplete statistics, traffic accidents caused by tire burst in highways of China take up 70% of the total number of the traffic accidents, and therefore great losses are caused to life and properties of people. According to the temperature and air pressure monitoring system of the car tire based on the wireless technology of the ZigBee, various fields such as wireless transmission, embedded type system on chip and automation control are combined, a control system of car tire air pressure, temperature real-time wireless monitoring and automatic spraying and cooling based on the technology of the ZigBee is designed, and a set of technical supports are provided so as to solve the problem of car tire burst hazards. The temperature and air pressure monitoring system of the car tire based on the wireless technology of the ZigBee comprises four portions including sense collection, wireless transmission and receiving, control treatment and an automatic spray cooling device, wherein the collection portion is composed of a temperature sensor, a pressure sensor and a flow sensor, a wireless ZigBee system on chip CC2530 chip is adopted by the wireless transmission receiving portion and the control processing portion is connected with a vehicle-mounted display screen, a stereo and setting keys, and the automatic spray device is composed of a water tank, an intelligent water meter, a water guiding pipe, a control switch and a water spray nozzle. The temperature and air pressure monitoring system of the car tire based on the wireless technology of the ZigBee has the advantages of being widely applicable to the field of automobiles, low in cost and power consumption, high-efficient, wireless-automation and the like.

Description

technical field [0001] The invention relates to an automobile tire temperature and air pressure monitoring system based on ZigBee wireless technology. The invention belongs to the field of wireless network communication technology, on-chip embedded system and automatic control system. Background technique [0002] With the development of the world economy and the continuous increase of basic investment, the improvement of road facilities and the sharp increase of expressway mileage have greatly increased the average speed of road traffic. This has undoubtedly brought huge benefits to the country and the people. wealth. But at the same time, traffic accidents, especially tire blowout accidents and brake deviation accidents caused by tire pressure differences have also increased rapidly, causing great losses to people's lives and property. According to incomplete statistics, traffic accidents caused by blown tires on domestic expressways account for 70% of the total number o...

Problems solved by technology

[0012] The patent number is: 200410086295.5, which designs a device for wirelessly monitoring tire pressure and temperature, but it also has obvious defects. The wireless transmitting and receiving device shares the antenna of the car radio, which is easy to cause interference. Complete the need to stop work when the temperature is low, in addition, it only provides a monitoring device, but does not propose how to automatically solve the treatment of this hazard
