| Summary: | Tire pressure monitoring system (TPMS) can be effective in preventing tire burst. However, traditional TMPS mostly uses the combination of pressure sensor, microcontroller and radio frequency (RF) transmitter, with excessive discrete components, low integration, poor reliability and high power consumption. The use of special TPMS sensor chip SP37 to design tire pressure monitoring module can overcome these shortcomings. Direct-type tire pressure monitoring module was designed based on SP37, and central receiving module was designed using microcontroller ATMEGA16 and RF receiving chip MC33594. Thus, the real-time monitoring of tire pressure and temperature is achieved. SP37 working mode can be flexibly configured via software, and power management implemented by low-frequency arousal technology and software greatly reduces system power consumption. Moreover, integrated RF transmitter improves anti-interference capability to protect communication reliability. |
