现有的有线煤矿监测预警系统只能在主矿道中应用,而复杂的地下工作区域仍是监测预警的“盲区”。为了能够有效地解决这一问题并且减少事故的发生,本文提出了一种基于无线传感器网络和嵌入式平台的监测预警系统,通过传感器,对环境中CO、CH_4、温度、湿度、光强等值进行监测。该系统采用了IEEE802.11MAC协议CSMA/ CA,以及DCF模式。同时采用了MESH无线传感器网络分析与管理平台,利用此平台收集每一个节点的信息,进行数据汇聚与进一步数据分析,根据所收集的各节点数据自动生成相应图表和做出超限报警提示。
The existing wired coal mine monitoring and early warning system can only be applied in the main ore channel, while the complicated underground working area is still the “blind spot” for monitoring and warning. In order to effectively solve this problem and reduce the occurrence of accidents, this paper presents a monitoring and early warning system based on wireless sensor networks and embedded platforms. Through sensors, the environmental parameters such as CO, CH_4, temperature, humidity, light intensity Monitoring. The system uses the IEEE802.11MAC protocol CSMA / CA, and DCF mode. At the same time, MESH wireless sensor network analysis and management platform is used. With this platform, information of each node is collected, and data aggregation and further data analysis are performed. Corresponding graphs are automatically generated according to the collected data of each node, and alarm of exceeding limit is made.
