Dangerous goods vehicle monitoring system based on Beidou satellite navigation and locating

The invention relates to a dangerous goods vehicle monitoring system based on Beidou satellite navigation and locating. The dangerous goods vehicle monitoring system based on Beidou satellite navigation and locating comprises a vehicle-mounted terminal system and a vehicle-mounted dangerous goods monitoring scheduling system, wherein data communication between the vehicle-mounted terminal system and the vehicle-mounted dangerous goods monitoring scheduling system is achieved through a network communication module, the vehicle-mounted terminal system comprises a first Beidou communication sending and receiving module, a first GSM/GPRS sending and receiving module, a vehicle sensing data collection module, an image monitoring module, a voice broadcast module used for being externally connected with a voice broadcast device or a horn, and a microcontroller. The dangerous goods vehicle monitoring system based on Beidou satellite navigation and locating has the advantages that a management center can carry out real-time monitoring, scheduling and united management when dangerous goods vehicles are in the moving state, a user can clearly learn about the positions of the dangerous goods vehicles in a real-time mode on an electronic map, the instantaneous speeds of the dangerous goods vehicles can be displayed, and information, such as overspeed records and illegal routes, of drivers can be stored in a central database.
