摘要
针对传统瞬时土壤测氡仪灵敏度低、体积大、数字化程度不高等缺点,研制出一种新型基于ARM7的GPS定位瞬时便携式土壤测氡仪。设计了全新的数据采集与控制电路,在保持测量准确性的同时,提高了仪器的灵敏度、数据采集精度和处理速度;软件设计引入嵌入式操作系统uc/OS-II,提高了仪器的稳定性和可操作性。野外测试结果表明,该仪器能够稳定、准确、快速地采集、处理数据,适用于地质和水文勘查中氡气浓度的定量测量。
At present, portable instruments for radon measurement are large in volume, poor in meas- urement sensitivity and digitized degree. We have designed a new portable instrument for radon measure- ment with GPS, new data acquisition and control circuit based on ARMT. It has higher sensitivity, accuracy and velocity. Embedded operation system （uc/OS-II） was used in software design for increasing stability and operability. The results of field assay showed that the instrument can be used for radon measurement in geologic and hydrographic survey.
