Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing monitoring system cannot capture the roof change signal in time and reflect the roof disaster situation more comprehensively and accurately, so the early warning effect is relatively poor. Therefore, the present invention provides a roof disaster monitoring system. The data is more timely and can capture roof motion signals more accurately, and can form comprehensive early warning indicators, with better early warning effects

Abstract

The invention provides a roof disaster monitoring system, comprising a ground server (1), network exchangers (2), intrinsically safe monitoring substations (3) and a plurality of sensors (4), wherein the network exchangers (2) are connected with the ground server (1); the intrinsically safe monitoring substations (3) are connected with the network exchangers (2); the sensors (4) are connected with the intrinsically safe monitoring substations (3); and controllers (5) are installed on the sensors (4) respectively, and used for controlling the sampling period of each sensor (4) and processing collected data, so that the constant-value and fixed-time sampling is realized. The roof disaster monitoring system provided by the invention not only can ensure that a roof motion signal is captured in time for more timely pre-alarm about a roof disaster, but also causes no affection on the transmission speed and no additional memory loads even in the cases of a great number of the collected data.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a coal mine roof disaster monitoring system. Background technique [0002] Roof accident is the most serious coal mine disaster that threatens the safety of coal mine production. Although my country's efforts to shut down small coal mines with serious safety hazards have been strengthened year by year, roof support technology has also been improved day by day, and monitoring technology has also been popularized and applied. However, roof accidents still occur frequently. In addition to the lack of understanding of the characteristics of coal seam pressure in the western mining areas that have been heavily mined, an important reason is the lack of more comprehensive, accurate and timely monitoring data to guide coal mine safety production. [0003] At present, in our country, although the mine pressure monitoring system or roof monitoring system has been widely used in the field of coal mine...
