摘要
由于CAFe装置温度监测点需求众多,若采用有线监测方式会产生大量的信号传输线缆,加剧装置周围的布线繁杂程度并且会导致其他设备故障排除困难,因此需要采取无线化的温度监测方式。文中设计一套基于ZigBee技术的无线温度监测系统,主要由数据采集层、传输控制层和用户层组成。系统通过使用ZigBee无线数传电台E180-DTU模块将多个温度监测点拓扑成一个无线传感器网络,并由串口服务器接入EPICS控制网,使用StreamDevice设备支持开发IOC程序对网络中各节点温度进行获取与发布,最后通过上层客户端对温度监测数据进行全局实时显示与报警。通过设置不同的无线网络拓扑结构,该系统能够非常容易地应对不同规模的温度监测需求。目前该样机系统已用于加速器上RFQ和MEBT段的温度监测,并且扩展监测了设备机房的多个环境温度监测点位,具有一定的应用价值。
Due to the large demand for temperature monitoring points in CAFe devices,a large number of signal transmission cables will be generated if wired monitoring method is adopted,which will increase the complexity of wiring around the device and lead to difficulties in troubleshooting other devices.Therefore,wireless temperature monitoring method should be adopted.A wireless temperature monitoring system based on ZigBee technology is designed,which is mainly composed of data acquisition layer,transmission control layer and user layer.In the system,ZigBee wireless data transmission station E180-DTU module is used to topology multiple temperature monitoring points into a wireless sensor network(WSN),which is connected to the EPICS(experimental physics and industrial control system)control network by the serial port server.Then,the StreamDevice is used to support the development of IOC(input/output controller)program,so as to obtain and issue the temperature of each node in the network.Finally,the upper-layer client is used to perform global real-time display and alarm of the temperature monitoring data.By setting up different wireless network topologies,the system can easily cope with the temperature monitoring needs of different scales.At present,the prototype system has been used for the temperature monitoring of the RFQ(radio frequency quadrupole)and MEBT(medium-energy beam-transport)sections of the accelerator,and has been extended to monitor several ambient temperature monitoring points in the equipment room,so it has a certain application value.
