摘要
针对工业无线通信和工业以太网发展情况,提出一种ZigBee/工业以太网网关。网关应用层采用Modbus/RTU主从式协议,以太网传输层采用UDP协议。文中介绍了网关硬件、软总体设计,重点介绍了Zigbee/Modbus地址映射和收发缓冲区设计。网关硬件设计基于Rabbit3000MCU和SZ05-ZBEEZigBee模块,软件设计基于DynamicC和μC/OS-Ⅱ实时操作系统。
In this paper, a gateway between ZigBee and Industrial Ethernet is presented for the development of Industrial Ethernet and industrial wireless communication. The Modbus/RTU master-slave communication protocol is integrated into the application layer, and the UDP protocol is applied in Ethernet transport layer . The overall framework of Software and hardware is introduced at first. Then the emphases is put on the technology which keep transmitting effectively, such as mapping ZigBee address from Modbus address ,the design of buffering and so on. The hardware is based on Rabbit3000 MCU and SZ05-ZBEE ZigBee module,the software design is based on Dynamic C and the μC/OS-U multi-task real-time scheduling system.
