Design of Continuous Monitoring System for Pressure,Temperature and Humidity in Radon Exhalation Rate Measurement Chamber

为研究氡析出率测量与气压温度湿度气象参数的关系,提出一种采用nRF2401无线网络进行数据传送的气压温度湿度气象参数的远程监测系统。该系统由6个气压温度湿度数据测量点、nRF2401无线通信模块和数据管理模块组成。系统监控流程是每个测量点测量数据经nRF2401无线通信模块发送数据,再经数据管理模块的nRF2401无线接收端接收采样数据,完成信息存储和处理。实验结果表明,该系统总体方案结构合理,软硬件设计切实可行,具有灵活的扩充性和伸缩性,能够满足氡析出率测量室气压温度湿度连续监测的需要。

In order to research the relationship between radon exhalation rate and meteorological parameters like pressure, temperature and humidity, a remote monitoring system for those meteorological parameters is raised,in which the wireless network nRF2401 is adopted to transmit data. Composed of 6 measuring points for pressure,temperature and humidity measurements, the wireless communication module nRF2401 and a data management module,the system uses nRF2401 module to sent the data each measuring point has monitored, then the receiving terminal in the data management module receives the data and finishes data storage and processing. Our experiment suggests that the overall structure of the system is rational, and the software and hardware are practical. With flexible expansion and scalability,the system can meet the requirement of continuous monitoring for pressure,temperature and humidity in a radon exhalation rate measurement chamber.
