Research On The Running Parameter Monitoring System Of Main Power Unit Of Watercraft Based On Network

The main power unit of watercraft running normally or not is directly influence the navigation security and economics of watercraft. So it is important to monitor the running parameters of main power unit. With the development of watercraft scale-up and automatization, high performance monitoring system is required to monitor the running status of main power unit by using the testing technique, single-chip microprocessor technique and network technique.A running parameter monitoring system of main power unit of watercraft based on network communication is designed in this paper. Firstly, the current development status of watercraft monitoring system is introduced, and the main research work in this paper is presented. Analyzed the running parameter of main power unit of watercraft, the parameters measuring methods are introduced. In this paper a monitoring system design scheme is presented. The multi-module distributed system and the centralized-monitor computer are used to monitor the multi-parameter and multiple units. A data acquisition module with integration; modularization; intelligence and based on network communication is designed to acquire and process the field analog signal to digital signal and transmit the data to the centralized-monitor computer by network.The signal input; signal process and data acquisition circuits of the data acquisition module are designed and how to implement network communication in single chip microprocessor is the key part. Through single-chip microprocessor selecting, network communication hardware and software designing, Ethernet chip driver programming and register configuration programming, the single-chip microprocessor implements network data communication. The initialization configuration of the data acquisition module is completed by serial communication.The experiments and the debugging results show that the system can work normally and satisfy the design demands.
