Research on Engine Data Acquisition and Monitoring Based on PLC
This paper mainly analyzes the application of CAN bus to the ECU of natural gas engine using J1939 specification.Through the combing of the data flow and the analysis of the address configuration of the J1939 and 485 conversion modules,the PLC system can directly collect the data of the engine into the program through the 485 port,and then cooperate with the start-stop,speed regulation and other wiring of the engine to form a complete control system with operation,monitoring,alarm and protection for the engine.
