基于移动GIS的天然辐射环境数据采集平台研发

Research and Development of Natural Radiation Environment Data Acquisition Platform Based on Mobile GIS

针对天然辐射环境外业调查,采用常规纸质手薄模式的缺陷,提出一种利用移动GIS技术开发天然辐射环境移动数据采集平台的新方法,从需求分析、系统作业流程、总体架构设计、数据库设计、功能模块设计等方面论述系统设计原理。基于该系统设计原理,开发了广东省天然辐射环境数据采集平台,解决了天然辐射环境外业调查常规方式存在成本高、效率低、容易出错等问题。基于二维码技术将手持端的样品信息传输至辐射实验室LIMIS系统,手持端开发Grubbs法则剔除可疑值技术以减少数据误差。移动GIS技术可应用于天然辐射环境移动数据采集平台的研发,以提高信息采集的效率。

In view of the defects of using conventional paper hand thin model in the field investigation of natural radiation environment,we pro-posed a new method for developing mobile data collection platform of natural radiation environment,and discussed the system design principles from the aspects of requirement analysis,system operation flow,overall architecture design,database design and function module design.Based on the design principle of this system,we developed a data collection platform for natural radiation environment in Guangdong Province,which solved the problems of high cost,low efficiency and error-prone in the conventional way of investigation of natural radiation environment.Based on QR code technology,we transmitted the sample information of handheld end to the LIMIS system of radiation laboratory,and developed Grubbs law to eliminate suspicious value technology in handheld side to reduce data errors.Mobile GIS technology can be applied to the develop-ment and design of mobile data acquisition platform in natural radiation environment,and improve the efficiency of information collection.
