Abstract:This paper introduces a design pressure sensor based on SCM and MSP430F149 MPXY8020A direct type tire pressure testing system, including data to the data acquisition module and display module two parts. In improving the Motorola TPMS solution is presented, based on the principle of the main circuit design TPMS and software design method. This system can be set via keyboard tyres, alarm MPXY8020A through determination of each tire pressure, and the actual internal by rf modules will tire pressure data transmission to the outside in the data acquisition module, show the real-time display tire pressure. The research purpose is to achieve direct tire pressure monitoring system of data acquisition module and display module design. The task is to improve economic significance, car safety quality, enhance the safety performance of high-speed car, and to enhance the technical level and competitive products to domestic car cost more common characters of consumers, make consumer get more cost-effective products and services. Topics of social significance, effectively reduce the vehicle for tyre fault caused by the traffic accident, thus reducing the great economic losses and casualties.
