Abstract
The invention discloses a vehicle dangerous material detecting system. The vehicle dangerous material detecting system is characterized by comprising a micro processor module, a wireless communication unit, a watchdog circuit, a GPS positioning unit and an input module. A gas sensitive sensor is connected with the micro processor module through a signal processing module, the micro processor module communicates with a remote public security system through the wireless communication unit, the input module and the GPS positioning unit are connected with the micro processor module, and the output end of the watchdog circuit is connected with the input end of the micro processor module. According to the vehicle dangerous material detecting system, the concentration of combustible gas in a vehicle is detected through the gas sensitive sensor, a driver and passengers in the vehicle are prompted through a voice alarm, the concentration information is transmitted to the remote public security system through the wireless communication unit, and therefore policemen can effectively handle the event in time; the system can be restarted when crashing, and the use failure rate is greatly reduced.
Description
Technical field
The invention discloses a kind of vehicle risk quality testing examining system, belong to bus safe driving technical field.
