摘要
传统的煤矿安全监测是依靠布局在特定点的传感器采集信号,通过有线传输的方式传输到控制中心,这种方式存在大量的测量盲区,不能依靠系统对危险进行预警,出现误判与漏判的现象;提出基于改进Apriori的煤矿安全预警系统设计方法,结合TT-CAN总线技术与无线传感网络技术去除井下测量盲点,保证数据的实时性,在软件设计阶段使用关联规则对影响煤矿安全生产的因素进行关联,识别相关性,实现对煤矿的安全性的多角度预警;实验证明这种关联故障诊断方法故障的判别准确率在83%以上,无线网络的数据传输丢包率低于0.18%,数据延时低于1.3s,性能稳定,具有很强的实用性。
Abstract; The traditional coal mine safety monitoring is depend on the layout in the specific point of sensors to collect signal, through the cable transmission to the control center, this kind of means there are a lot of measuring blind area, can＇t rely on home system for risk early warning, appear miscarriage of alarm or false alarm. Based on the improved Apriority coal mine safety early warning system design method, combined with the TT CAN bus technology and wireless sensor network technology to remove downhome measurement blind spot, to en- sure that the data of real time, in software design phase using association rules of safety production in coal mine influence factors linked, i- dentification, and to realize the correlation to the coal mine safety early warning of angles. Experiments prove this association fault diagnosis methods fault discriminant accuracy rate in more than 83 V00, wireless network data transmission packet loss rate lower than 0. 18M, data de lay less than 1. 3 s, stable performance, strong practicability.
