现场总线架构土壤氡监测局域网

A Radon in soil Detecting Area Network Based on Field Bus

本文研制了一套利用CAN总线架构的土壤测氡系统,该系统与传统测氡设备相比,可实现几公里范围内的多点同时测量,不仅提高工作效率,还排除因测量时间不同引起的误差,增加了数据的可比性;开发了系统组建局域网所需的网络协议,具有组网灵活性强,兼容点名、广播等多种通讯形式及双主机结构等特点。本套系统特别适合区域氡水平调查、氡运移规律研究等领域的应用需求。

A radon detecting area network system based on Controller Area Network （CAN） bus was built up. Compared with traditional devices, This system allow experimental data from vary places in range of several kilometers achieved at the same time. So work efficiency and comparability for measurement result can be raised and error can be eliminated. A protocol applied area network was designed. It has the advantages of flexible networking and Double hosts. Broadcasting or spot-to-spot communication can be realized. The system can meet the requirement of vary application regions, such as area radon level survey , radon transportation rules study , and so on.
