摘要: 针对目前大多数顶板下沉监测仪存在的数据收集工作量大、顶板下沉数据无法上传地面等问题,文章提出了一种矿井顶板下沉信号远程传输系统的设计方案,详细介绍了系统的工作原理、数学模型,并确定了关键参数,同时给出了系统硬件电路设计。该系统将顶板下沉数据以频率信号的形式远程传输至矿井安全监测监控系统通信分站的模拟量接口,使得矿井安全监测监控中心可实时监测和采集各个监测点的顶板下沉状态和数据,提高了顶板下沉监测的连续性、真实性。现场运行表明,该系统易与矿井通信分站通信,各项运行指标完全满足煤炭行业所规定的国家标准。Abstract: To solve the existing problems of most roof descending monitors such as heavy workload of data collection and unable to upload roof descending data to surface, the paper proposed a design scheme of remote transmission system of mine roof descending signal.It introduced working principle,mathematic model of the system in details,and determined the key parameters as well as gave design of the hardware circuit of the system.The system can transmit the roof descending data with frequency signal mode to analog interface of communication substation of safety monitoring and control system of mine so as to the safety monitoring and control center of mine can monitor and collect state and data of roof descending of each monitored point in real-time,which improves continuity and reality of roof descending monitoring.The field operation showed that the system is easy to communicate with mine communication substation and each operation index can meet national standard ordained by coal industry.
