The paper,first of all,gives a discussion on the necessity of strengthening the security supervision system,and a brief introduction to the function of CAN bus.The supervision system consists of a number of intelligent nodes and topper computers.The intelligent nodes perform the function to collect field data;and the topper computers perform the function to alarm irregularities.The paper also provides a circuit of hardware and list of software for the overall structure of the system and for the intelligent nodes.In addition,the paper illustrates the construction of the nodes,and points out the items of attention when designing.Furthermore,through simulation test and by analyzing the reliability of CAN bus and the percentage of the bus,the paper provides reference data for the design of the system.In the final step,the paper proves that the adoption of the CAN-based security supervision system structure is a better choice.
