Design and Realization of CAN Bus in a Marine Data Monitoring System

In view of actual requirement of remote data monitoring in the marine environment,a hardware and software method of data monitoring system for marine is developed,which is based on the fast and mixed MCU.Using C8051F040 and its built-in function modules as the core of the control system and CAN-bus for the connection of each sensor nodes can form the network of the field sensor nodes,and display real-time the data through host computer.The result shows that the monitoring system can transmit under the rate of 9 600 bit/s normally,stable and applicable in real-time.It has a broad application prospects in the marine environment.
