Design And Implementation Of Radon Concentration Monitoring Software System Based On Cloud Server

Radon is a radioactive element.The alpha particles produced by the decay of radon and its progeny will cause internal radiation to the human respiratory tract,especially serious damage to lung cells,which leads to an increase in the probability of people suffering from lung cancer.As an important indoor air quality index,radon gas concentration monitoring is the prerequisite for removing radon and reducing radon in the high radon potential area.Conventional radon concentration monitoring instruments are mostly single-point measurement,and the data is stored in the instrument,the recovery workload is large,and the real-time and sharing of data is poor.Especially when multiple radon meters are used for regional continuous monitoring,the above problems are more prominent.Based on the GB 50325-2020 national standard,China University of Geosciences(Beijing)has developed a continuous radon meter with the Internet of Things function,which realizes the functions of radon concentration detection and remote data transmission.In this paper,combined with the hardware platform of the radon meter,a set of automated radon concentration monitoring software system is developed to realize the real-time collection of radon concentration monitoring data,cloud platform storage,data display and other functions,and to carry out the long-term continuous monitoring of regional radon concentration in the next step.Laid the foundation.The software system mainly includes three parts: TCP data collection and storage program,B/S software architecture Web application program,and C/S software architecture Android application program.The TCP data acquisition and storage program is based on the communication protocol of the radon meter,written using Socket programming,and deployed on the Alibaba Cloud server platform,using the My SQL database as the back-end data management container to realize the radon meter transmitting and storing data to the cloud through the wireless transmission module Server database.The web-side application uses Java Web development technology and is implemented using SSH(Spring+Struts2+Hibernate)open source framework programming.It includes 4 functional modules: instrument management,data management,user management,and Android management.The Android application program is programmed in Java language under the Android Studio platform,and uses the HTTP communication protocol to request data from the server.The data format is encapsulated in JSON.It includes three functional modules: user management,instrument management,and historical data query,enabling mobile phones and other mobile phones.The function of the terminal to monitor radon concentration data.Through laboratory testing,it is verified that the TCP data acquisition and storage program deployed on the cloud server can receive and store the radon concentration data sent by multiple radon meters at the same time.Use Load Runner automated testing software to perform functional and performance tests on the Web-side software.The software system functions are normal and the performance is up to expectations.The software system can remotely monitor radon concentration data information online,realize the Internet of things,radon concentration data sharing,and visualization of the radon meter hardware,and meet the expectations of distributed radon concentration monitoring data management,which can effectively improve the efficiency of radon measurement.
