中文摘要：
为了解决工业现场设备通信电缆不利于组装和维护，提出了利用ZigBee网关将所有设备组成无线网络实现无线通信。利用zigBee协议栈应用层完成协议数据转换，基于地址映射表完成MODBUS站号和无线网络地址的匹配，实现MODBus和无线网络的网关功能，完成数据透明传输。实际测试表明，无线模块的发射功率、接受灵敏度、通信距离、误包率、速度满足工业应用的实时性安全性要求，改进网络性能比传统网络大大提升，已应用于实际PLC通信和参数配置中，可代替传统通信方式。
英文摘要：
In order to solve the communication cable in the industrial site equipment against assembly and maintenance,Zig- Bee gateway is used to assemble all equipment into a wireless network to realize wireless communications.The protocol data is transferred by the application layer of ZigBee protocol stack.Based on address mapping table the match is completed between MODBUS station number and wireless network address.Gateway functions are realized among MODBUS and wireless network.Data transparent transmission is completed.The actual test is made to prove that the transmitted power,accept sensi- tivity, communication distance, mistaken package rate, speed of wireless module meet industrial application of real-time security demands.The improved network performance compared to traditional network greatly ascends.The gateway has been applied in practical PLC communication and parameter configuration,and can replace the traditional way to communicate.
