基于无线传感网的矿山井下通讯系统关键技术研究

基于无线传输协议,将无线通讯与有线通讯相结合,实现井下事故区域通讯系统的自愈,保障事故发生后矿井稳定的联络通讯、监测及定位;研究基于无线自组网技术与有线通讯相结合的自愈机理,开发可以自愈的通讯组件。文章基于码分多址的预约(ALOHA)防碰撞算法,结合传感网拓扑优化算法最优安置无线接收终端和路由,使传输监控系统达到传输最优目标。为井下监测、定位、通讯、安全预警、系统维护、跟踪、回放、查询、统计等重要数据和有用信息提供可靠传输支持,为井上营救提供重要依据。

Reserch on Underground Communication System Based on Wireless Sensor Networks

Based on the wireless transmission protocol,this article describes wireless communications and wired communications combine to achieve self-healing of the regional communications system for underground accidents,in order to protect the accident occurred the mine stable contact communication,monitoring and positioning.This paper presents self-healing mechanism based on a combination of wireless ad hoc networks and wireline communications,development communications components that can be self-healing.Based on the Anti-collision algorithm of the ALOHA,combined with the sensor network topology optimization algorithm for optimal placement of the wireless receiver terminal and routing,transmission control system to achieve optimal transmission target.Monitoring data and useful information can be provided to reliable transmission support when rescue.
