【摘要】：矿区掠夺性开采使矿区的生态环境严重恶化，大气环境遭到严重污染，对矿区的大气环境进行监测和保护逐渐受到人们重视，建立矿区大气环境监测系统来对矿区大气环境的实时监控和预警保护，来保护矿区大气环境，保证矿区的开采能够可持续发展。本系统利用传感器对矿区的环境参数进行监测采集，利用GPS定位技术对监测终端进行实时定位，并在终端利用ARM技术开发嵌入式系统，对采集数据信息和GPS信息进行储存、处理和管理，对监测终端的工作运行进行控制，并通过GPRS技术根据程序功能设定自动传送数据给后台数据管理系统，也可以监测终端通过GPRS接收后台发布的指令，并对执行的功能任务进行优先权选择，优先执行紧急监测任务，GPRS技术实现后台管理系统对监测终端的远程控制和数据传输。后台管理系统在GIS技术支持下实现整个矿区大气环境监测系统的地图化、可视化呈现，建立空间数据库，结合ORACLE技术对数据库进行管理，，利用WebService技术和ADO.NET技术连接数据并进行调用处理，实现对整个矿区大气环境进行实时监测，信息查询、处理等。本文针对监测终端的GPS定位精度进行深入研究，通过相位平滑伪距差分定位算法来提高GPS定位精度，设计周跳探测的方法，进一步提高定位精度，确保监测终端的采集数据的有效性，只有对监测数据进行具体的地理信息描述，才能实现对矿区大气环境的精确监测，有效帮助相关部门根据监测数据制定有效的合理措施，防止大气环境污染，保护矿区大气环境。
[Abstract]:Predatory mining in mining area has caused serious deterioration of ecological environment and serious pollution of atmospheric environment in mining area. People pay more and more attention to monitoring and protection of atmospheric environment in mining area. The atmospheric environment monitoring system of mining area is established to monitor and protect the atmospheric environment in real time and early warning, to protect the atmospheric environment of mining area and to ensure the sustainable development of mining area. The system uses sensors to monitor and collect environmental parameters of mining area, real-time positioning of monitoring terminal by GPS positioning technology, and the embedded system is developed by arm technology in the terminal to store the collected data and GPS information. Processing and managing, controlling the operation of the monitoring terminal, automatically transmitting data to the background data management system according to the program function set by GPRS technology, also monitoring the terminal to receive the instructions issued by the background through GPRS. In addition, priority is given to the functional tasks carried out, and the emergency monitoring task is given priority to the GPRS technology to realize remote control and data transmission to the monitoring terminal in the background management system. With the support of GIS technology, the background management system can realize the mapping, visual presentation, establishment of spatial database and management of the whole mine atmospheric environment monitoring system with Oracle technology. Web Service technology and ADO.NET technology are used to connect data and transfer the data to realize the real-time monitoring, information query and processing of the atmospheric environment of the whole mining area. In this paper, the GPS positioning accuracy of the monitoring terminal is deeply studied, and the GPS positioning accuracy is improved by using the phase smoothing pseudo-range differential positioning algorithm, and the cycle slip detection method is designed to further improve the positioning accuracy. To ensure the validity of the data collected by the monitoring terminal, only by describing the monitoring data with specific geographical information, can the precise monitoring of the atmospheric environment in the mining area be realized, and relevant departments can be effectively helped to formulate effective and reasonable measures according to the monitoring data. To prevent atmospheric pollution and protect atmospheric environment in mining area.
