摘要
简要介绍了胎压监测系统(TPMS)的组成,提出了一种基于新型传感器SP37的胎压监测系统。该系统采用SP37和MAX1473作为无线收发芯片,详细阐述了其软件和硬件设计中的关键技术。实际测试效果表明,该系统接收灵敏度可达到-100 dBm,高速跑车时速100 km时工作稳定。
This paper briefly introduces the structure of Tyre Pressure Monitoring System （TPMS）, and puts forward a kind of TPMS based on new sensor SP37. It adopts SP37 as the transmitter and MAX1473 as the receiver and further on it illustrates the key technology in the hardware and software design in detail. The actual test result indicates the sensitivity of system can reach-100dBm, and the system works steadily when velocity of car is 100km/h.
