摘　　要：采用传统的单点土壤氡测试技术进行多点监测,工作效率低,还因氡气的释放与运移有一定的涨落,影响不同测点间数据的可比性。研制多参数土壤氡测量仪,并引入CAN(Controller Area Net-work)总线技术搭建局域测氡网络,实现多点同时测量,能满足区域氡水平调查、氡运移规律研究及工程地质异常区圈定等多领域的应用需求。系统样机的标定结果与商品化测氡仪作对比,体现出较好的一致性。It doesn＇t work efficiently to apply normal Radon detecting technique of single point to an area survey. Due to the swing of radon release and transportation, comparability for measurement results from vary places is poor. Radon in soil detectors with environmental parameters monitor was developed. Thanks to the techniques of Controller Area Network （CAN） bus, a radon detecting area network system was built up. These allow experimental data from vary places achieved at the same time, and can meet the requirement of vary application regions, such as area radon level survey, radon transportation rules study, and hot spot position in engineering or geology. Comparison was made between the results from the protocol system and a commercial radon instrument in calibration test. It shows a good agreement with each other.
