Abstract
In order to solve the problems of reliable and fast access to industrial Ethernet ring network of coal mine equipments,access communication system based on isolated CAN network is designed.It adopts ADM3052 for design of CAN physical layer transceiver.A detailed analysis is carried out about calculate control parameters so that the isolated CAN network can run at a high speed and CANopen protocol is used for CAN network application layer communication protocol.The system uses isolated CAN network for long distance serial communication.It guarantees real-time character and physical security of mine communication in harsh environment.
