摘　　要：采用现场总线技术构建分布式监控通信网络系统,设计了基于AT89C52单片机的CAN总线控制器和RS-485通信节点硬件电路,介绍了CAN报文协议和MASTER-K120S系列PLC专用通信协议,并给出了通信软件的具体实现,连接计算机完成了数据的发送与接收。Fieldbus technology was used for constructing the distributed monitoring net system for communication. CAN bus controller and hardware circuit of RS-485 communication nods were designed using singlechip of AT89C52. CAN message protocol and special protocol of PLC of MASTER-K120S series were introduced and the specific implementation of communication software was provided. Sending and receiving data was completed through connecting the computer.
