摘　　要：针对目前工业控制过程中有线通信成本较高、组网不够灵活的问题,采用ZigBee Pro协议,提出了一种低成本、高可靠性、低误码率的无线组网监控系统设计方案。该系统的无线部分以TI公司的CC2530为核心,由协调器、路由器和终端设备3部分组成,并通过协调器与上位机进行交互操作。同时,采用自定制协议,通过串口实现ZigBee网络与西门子S7-200 PLC自由口的通信。现场应用已取得较好的控制效果。Aiming at the current situation of wired communication in industrial control process, e. g. , high cost and inflexible of networking, the design strategy of a wireless monitoring system is proposed. The system uses ZigBee Pro protocol j and features low cost, high reliability and low bit error rate. With TI CC2530 as the core, the wireless part of the system is composed of three sections, i. e. , coordinator, router, and terminal device. The interaction with host computer is via coordinator. In addition j by adopting self-defined protocol, the communication between ZigBee network through serial port and Siemens S7-200 PLC free port is implemented. Better control effect is achieved in field application.
