Vehicle Natural Gas Leakage Detection System Based on HWD32F103 Design

In order to ensure the safe operation of urban vehicles, a vehicle natural gas leakage detection system based on a domestically produced HWD32F103 microcontroller was designed. The system consists of a host, a set of leakage sensors, and temperature sensors. The sensors transmit the measured temperature and gas concentration information to the host through CAN communication, and display the measured data in real time through the TFT-LCD color screen on the host. The system has data storage, offline detection, and alarm functions. The experiment shows that the system can timely and accurately detect natural gas leaks and temperature anomalies in vehicles, ensuring the safety of the vehicle during operation.
