Design of a Direct TPMS System Based on SP37

Article Preview

Abstract:

This paper introduces the TPMS installation method and system composition, and on this foundation, a kind of scheme of the TPMS emitter based on the SP37 chip is proposed. Monitor use the microprocessor and TDA5230 chip to realize the wireless data receiving, and this paper details the key technology in the hardware and software design. The actual test results show that, sensitivity of the wireless data receiving of the system not less than -105dBm, and the system works stability when speed of car is 80 ~100 km/h.
