Study on Monitoring and Control System of Vehicle-Mounted Rig Based on CAN Bus

The monitoring and control system based on CAN bus was designed in order to implement the data reliable transmission between all nodes in the control system of the vehicle-mounted rig. Firstly, the hardware structure of the monitoring system was designed in the paper, and two CAN network was built, which one CAN network used CANopen protocol and the other used J1939 protocol and CAN2.0B protocol, that it saved the resource of hardware and software. Secondly, all CAN protocols , program flow chart and software with Labview were designed in detail. The application results of the actual engineering showed that it realized the function of data transmission with each console and real-time monitoring.
