【摘要】：巷道顶板的位移监测是煤矿安全生产中的重要问题。论文以无线传输方式为主完成了巷道顶板离层在线监测系统,为巷道顶板支护工作提供了可靠的技术支持。本课题设计的巷道顶板位移数据的采集与传输系统,分为三个主要部分：顶板离层仪节点、通信分站及上位机。顶板离层仪节点在巷道内每隔50m安装一个，定时采集顶板离层数据，并且各个节点以接力方式通过ZigBee或485混合传输的方式把数据传送至通信分站;每条巷道配置一台通信分站,存储本巷道内所有节点的离层数据并在本地显示,同时也通过以太网或485的方式与上位机进行数据通信;上位机汇集各巷道通信分站的离层数据,进行存储、管理及分析。本系统中的顶板离层仪节点电源以电池为主,低功耗成为设计中的主要制约因素,我们设计了定时休眠与唤醒的同步通信机制，成为节能的主要措施。实际工作中，每台通信分站最多可以连接64台顶板离层仪节点，可以满足3000m长的巷道顶板离层监控需求。顶板离层仪节点的位移测量精度达到5mm以内，在经过软硬件协同的低功耗设计后，平均每天的耗电量仅为2.63mAh，配备一颗2.4Ah锂电池供电，，使用时间可达1年。本课题设计的巷道顶板位移监测系统通过了重庆煤炭科学研究院的产品认证，目前已经在山西四候煤矿和王庄煤矿得到了应用。
[Abstract]:Displacement monitoring of roadway roof is an important problem in coal mine safety production. In this paper, wireless transmission is the main way to complete the online monitoring system of roadway roof separation, which provides reliable technical support for roadway roof support. The data acquisition and transmission system of roadway roof displacement is divided into three main parts: the node of roof separation device, the communication sub-station and the upper computer. Every 50 meters in the roadway, the node of the roof seperator collects the data of the roof layer at a fixed time, and each node transmits the data to the communication sub-station by ZigBee or 485 by way of relay, and each roadway is provided with a communication sub-station, The data of all the nodes in the roadway are stored and displayed locally. At the same time, the data communication with the host computer is carried out by Ethernet or 485. The upper computer collects the data of each roadway communication sub-station for storage, management and analysis. In this system, battery is the main power supply in the roof layer separation device, and low power consumption is the main restriction factor in the design. We have designed the synchronous communication mechanism of timing dormancy and wake-up, which has become the main measure of energy saving. In practice, each communication sub-station can connect up to 64 roof dissociator nodes, which can meet the monitoring requirement of roadway roof separation layer with a length of 3000 m. The displacement measurement accuracy of the top layer separation device is within 5mm. After the low power design of software and hardware cooperation, the average daily power consumption is only 2.63 mAh. it is powered by a 2.4Ah lithium battery, and the service time can be up to one year. The roadway roof displacement monitoring system designed in this paper has passed the product certification of Chongqing Coal Science Research Institute and has been applied in Shanxi Sihui Coal Mine and Wangzhuang Coal Mine.
