In order to improve the efficiency of on-board and fault detection of refueling vehicle for military group vehicles, a state monitoring system of refueling vehicle based on on-board multi-source data acquisition is designed. On the basis of collecting on-board data information, Beidou navigation system and various sensing devices are installed, and the running status of the vehicle itself and on-board equipment is visualized by using on-board networks such as CAN bus, Bluetooth and display and control terminals, so as to realize visual vehicle scheduling. The test results show that the system can display the status of vehicles and on-board equipment in real time, and the command center can carry out remote monitoring and command dispatch.
