Wireless tire pressure monitoring system based on single chip microcomputer
Abstract:Vehicles is the most important means of transport. In recent years, every year a large number of cars in the manufacture and put into use, and the pace of manufacturing is still accelerating. The increase of vehicles, the frequency of traffic accidents caused by more and more high, which because of vehicle tires burst caused by the largest proportion of traffic accidents, so early detection of abnormal tire pressure tires to reduce the probability of vehicle tire failure to improve the car Of the driving safety is of great significance. In recent years, with the development of microelectronics, computers, automatic control, sensors and other technologies, automation technology is more and more widely used in many traditional industries, completely changed the traditional mode of production. More and more engineers and scholars have applied the new technology in the control system,
In this paper, a variety of industries in the field of automation solutions, combined with NRF24l01 wireless transmission module, based on microprocessor-based tire pressure monitoring system design. The temperature and pressure of the tire are detected and transmitted to the host computer by the MCU and the temperature transmitter and the pressure transmitter. The host computer receives the information and displays it through the LCD, and makes judgments and warnings on whether the information is abnormal.
Key words:MCU; tire pressure; NRF24l01; temperature sensor; pressure transmitter
