[Abstract]:In recent years, with the rapid development of electronic technology and fieldbus technology, more and more new technologies have been applied in the field of ship automation. It can accurately and reliably monitor the engine working process. If there is a fault, the system can send out sound and light alarm according to the setting, and provide the safety protection mechanism. The network control system based on fieldbus has become the development direction of the marine mainframe remote control system, which has certain significance for the continuous promotion of ship automation and digitization, and for improving the automation technology of the main engine monitoring system. According to a scientific research project, by analyzing the requirements of the system, the specific functions of different modules, and then comparing the more popular bus technology at home and abroad in detail, the paper determines the required technical parameters. The fault standard and CAN bus are selected as the channel of information exchange between modules. According to the functional requirements of the main engine monitoring system and the collecting characteristics of the control signal and alarm signal, the CAN network is designed, which is composed of the bridge, the centralized control room and the engine room controller. And its application layer protocol accords with SAE J1939 protocol based on CAN bus. On the basis of determining the whole network, the system is divided into independent modules, and according to the function of each independent module, the intelligent node of the host monitoring system is designed. This paper first introduces the overall structure of the monitoring system and the overall structure of the module designed in this paper, and then analyzes the pin function and CAN function of the Infineon XC2267M chip. Finally, the CAN bus communication interface circuit of the module, the important pulse signal of diesel engine, the acquisition of analog signal and switch signal, the conditioning circuit of storage and transmission, the LCD display circuit and the peripheral circuit of single chip microcomputer are designed by modularized design method. Finally, referring to the SAE J1939 protocol, the paper uses CANoe bus simulation software to extract the diesel engine CAN bus network information, analyzes the hardware-in-the-loop simulation test, and verifies the rationality and feasibility of the system circuit design.
