| Along with our country economy growing, there is a strong demand for coal in China. But coal production environment is very bad, so coal mine accidents often happen. The country attach great importance to coal mine safety and adopt a series of measures to strengthen safety in production and management. Many coal mines have been equipped with coal mine safety monitoring system, to some extent, this effectively prevent the occurrence of major accidents. But most of the coal mines can not monitor underground personnel and environment. Especially, if some key positions and key working are out of supervision control, it will cause security risks. In addition, there will bring great difficulties for search and rescue once accidents happen because of the complex terrain of downhole.This system which be mentioned in this paper is just designed base on above reasons. The system realizes miner moving status query and downhole environment condition’s real-time monitoring which is as multi-management system. According to the software engineering design idea, the personnel positioning and environment monitoring system based on the analysis of the demand, object-oriented software development methods will be adopted. It will conclude Zigbee network technology, MEMS sensor technology, the Java programming language and SQL Server2008 database related technologies.System mainly completes miner personnel positioning, miner moving trajectory, personnel distribution status query and environment monitoring of coal mine include temperature, humidity and gas. It also achieves personnel information registration, hardware inspection, statistics and so on. System has gone through the actual operation and test, it can realize real-time positioning and collect the environment data in real-time, the alarm information can be displayed on the client. This will meet the demand of the actual business of coal mine safety production and greatly improve the work efficiency. |
