The Research of Tunnel Roof Separation Monitoring Device Based on STC12C5A

Abstract

Tunnel roof separation monitoring is an important research content of tunnel supporting technology, it is of great significance to guarantee the safety of mine production. The traditional detection methods of roof separation have disadvantages of low precision, poor reliability, high cost, and the comprehensive analysis of measurement results is difficult. In the paper, a roof separation monitoring device based on STC12C5A is proposed. It has the core of STC12C5A single-chip microcomputer, and realizes the accurate measurement of displacement by using the fine drag-rope displacement sensor, and realizes the data communication and sharing by using bus interface. The device can achieve real-time, reliable monitoring of roof separation condition and also can make pre-caution to the possible production accident.

Construction and Application of On-Line Roof Separation Monitoring System Based on High-Precision FBG Indicator

“…It is therefore of vital importance to monitor roof separation to avoid the occurrence of roof accidents [1][2][3]. At present, means of monitoring roof separation mainly include on-line monitoring and the non-online monitoring method [3][4][5][6]. The non-online monitoring instrument represented by the mechanical roof separator is extremely dependent on artificial observation to collect separation information, which has the disadvantages of unavoidable personal error, discontinuous monitoring data, high human cost, and disability of real-time monitoring [7].…”
