DCS (data communication system) control system based on wireless monitoring of coal road roof separation layer

Abstract

The invention provides a DCS (data communication system) control system based on wireless monitoring of a coal road roof separation layer. The DCS control system comprises a wireless network and a plurality of monitoring subsystems. Each monitoring subsystem is provided with a digital-analog transmission module and a plurality of monitoring points. Each monitoring point is provided with a sensor. All sensors in the same monitoring subsystem communicate with a data processor which receives and processes data by the aid of the digital-analog transmission module. The data processor communicates with a main controller through the wireless network. An output end of the main controller is electrically connected with a main server arranged on a coal-mine monitoring master station through an exchanger. By the DCS control system, wiring is reduced, information of the monitoring subsystems of various production coal mines is shared and comprehensively analyzed and processed, and resources are shared. Centralized management, operation and display are realized, while functions, load and hazardousness are decentralized, and dual purposes of on-site early warning and remote real-time monitoring are achieved.

Description

technical field [0001] The invention relates to a DCS control system, in particular to a DCS control system based on wireless monitoring of coal roadway roof separation. Background technique [0002] In coal mine production, the roadway surrounding rock will be delaminated due to the tension and shear damage of external force, especially the roof delamination is more likely to occur in the roadway supported by bolts. With the improvement of production capacity, the increase of mining intensity and the shift to deep mining, the problem of roof safety has become more and more prominent. Among all kinds of coal mine accidents, roof accidents still rank first. When the roof separation exceeds a certain range, it means that the roof is in an unstable state. If support measures are not taken in time, malignant roof accidents such as roof fall will occur, which is directly related to the safety of the staff and whether the production activities can be carried out smoothly.

AI Technical Summary

Problems solved by technology

However, it is necessary to manually observe and measure the readings of the roof abscission layer and establish a ledger; and the data can only be obtained in the working area. danger to workers; and because the mining roadway in the working face of the roadway is very long, it is impossible for the observers to accurately grasp the changes of each roof delamination instrument every day, that is, the automatic monitoring and data transmission of the roof delamination cannot be realized, so the staff cannot Take corresponding measures in time to prevent roof instability, and sudden damage will inevitably occur, which will bring hidden dangers to the safe production of coal mines

[0004] In addition, at present, the monitoring system for the hydraulic support of the fully mechanized mining face in the coal mine, the monitoring system for the roof of the roadway and the surrounding rock separation layer, the monitoring system for the advanced support stress of coal and rock, the monitoring system for the bolting support stress of the surrounding rock of the roadway, etc., and its monitoring methods They are all independent, so the monitored data cannot be comprehensively analyzed and processed; the delamination and deformation monitoring devices of each field connection have many deficiencies such as difficulty in laying cables underground, many cables, and difficult maintenance; independent monitoring, which also restricts the sharing of resources in the entire mining area
