Description
Technical field
The present invention relates to a kind of monitoring system, particularly a kind of coal mine roof plate disaster monitoring system.
Background technology
Roof accident is to threaten the most serious colliery disaster of Safety of Coal Mine Production.Though closing down the dynamics in the serious little colliery of potential safety hazard, China strengthens year by year; The roof timbering technology is also promoted day by day; Monitoring technology is also in the application that constantly puts it over; Yet roof accident still frequently takes place, and this increases in a large number, ore deposit, the mine of western coal seam pressure characteristics of a large amount of inputs exploitations are understood the reason such as less except the high strength stope, and important reasons lacks exactly more comprehensively more accurately more timely that monitored data instructs Safety of Coal Mine Production.
At present, in China,,, and fail to play a key effect in fact to instructing Safety of Coal Mine Production also to be in the status, edge though mine pressure monitoring system or top board monitoring system have obtained extensive use in the field, colliery.Wherein reason mainly concentrates on 2 points: the one, and data acquisition is oversize blanking time; Data volume for fear of gathering is too big; The time in sampling interval of monitoring system setting only can be satisfied the polling period requirement of the shortest 30s, causes in time capturing the movement of roof variable signal, and real-time is poor; The 2nd, the warning index that detection system provides directly is used to estimate the top board disaster even only provides initial data very little, estimates the top board disaster through virgin stress or displacement data, and does not form warning index, causes evaluation conclusion unilateral, even loses accurate.For example; Patent CN201236722Y discloses a kind of top board dynamic monitoring system, and monitoring system comprises fully-mechanized mining working surface hydraulic support monitoring subsystem, back and surrounding rock separation layer monitoring subsystem, the leading bearing stress monitoring subsystem of coal petrography and roadway surrounding rock bolt support stress monitoring subsystem four sub-systems.What this monitoring system adopted still is the routine data acquisition mode, and real-time property is poor; This monitoring system has just enlarged horizontal monitoring range simultaneously; Improve the top board monitoring accuracy with more Monitor Sub-Station of Less; Fail to develop depth, form more comprehensively the accurately warning index of reflection top board disaster situation, still relatively poor to the early warning effect of top board disaster.
Summary of the invention
Technical problem to be solved by this invention is that existing monitoring system can't more in time catch top board variable signal and reflection top board disaster situation more comprehensively accurately; Thereby the early warning effect is relatively poor, for this reason, the invention provides a kind of top board disaster monitoring system; Image data is more timely; More can accurately catch the movement of roof signal, and can form comprehensive warning index, the early warning better effects if.
The technical scheme that the present invention adopts is following:
A kind of top board disaster monitoring system; Comprise ground-based server, the network switch, intrinsic safety type Monitor Sub-Station of Less and some sensors, the said network switch is connected with said ground-based server, and said intrinsic safety type Monitor Sub-Station of Less is connected with the said network switch; Said sensor is connected with said intrinsic safety type Monitor Sub-Station of Less; Said sensor is equipped with controller, in order to the sampling period of control sensor with to the processing of image data, realizes the definite value timing sampling.The concrete implication of definite value timing sampling promptly is to set a less sampling period earlier, and the cycle can be merely a millisecond magnitude, samples according to setting the sampling period then; During each sampling with sampled value with preestablish threshold values relatively; If greater than threshold values, then carry out record, if less than threshold values as new data; Then abandon not record, threshold values is confirmed according to the actual conditions of work plane.
In above-mentioned top board disaster monitoring system, said controller comprises power management part, single-chip microcomputer, storage area, bus control circuit and digital-to-analogue conversion part.
In above-mentioned top board disaster monitoring system, said ground-based server is equipped with the warning index analysis software.Working surface hydraulic support working resistance, ahead work face bearing pressure, roadway surrounding rock stress, roadway roof absciss layer and anchor shaft anchor cable stress and so on physical quantities real time data are after sensor monitors obtains; Be transferred to ground-based server at last through Monitor Sub-Station of Less, the network switch, store in the database on the ground-based server.The warning index analysis software that is installed on the ground-based server will in time access monitored data automatically from database; Computational methods and calculated with mathematical model according to preset go out each warning index value; Estimate top board disaster state according to the warning index value, and provide different early warning signals.Warning index can comprehensive and accurate reflection top board disaster state, warning index comprises the working surface hydraulic support setting load, increases the resistance rate, between the safety valve unlatching rate, hydraulic pressure before and after post lack of uniformity and work plane press step pitch etc.
In above-mentioned top board disaster monitoring system, the said network switch has more than two, is connected to form ethernet ring network between the network switch, connects through optical fiber between the said network switch.
In above-mentioned top board disaster monitoring system, be connected with more than one intrinsic safety type Monitor Sub-Station of Less on the said network switch, be connected through transmission cable between said intrinsic safety type Monitor Sub-Station of Less and the said network switch.
In above-mentioned top board disaster monitoring system, be connected with more than one sensor on the described intrinsic safety type Monitor Sub-Station of Less, sensor is pressure sensor or displacement transducer.
Technique scheme of the present invention is compared prior art and is had the following advantages:
1. top board disaster monitoring provided by the invention system; Comprise ground-based server, the network switch, intrinsic safety type Monitor Sub-Station of Less and some sensors; Controller is installed on the sensor, has realized regularly definite value sampling, therefore; Not only can guarantee in time to catch the movement of roof signal, but also can not influence transmission speed too much and increase the storage burden because of image data.
2. top board disaster monitoring provided by the invention system; Its ground-based server is equipped with the warning index analysis software; Can in time monitored data be formed warning index, through comprehensive warning index data top board disaster state is provided the early warning indication, so the early warning effect be more accurately more comprehensive.
3. top board disaster monitoring provided by the invention system; Can form ethernet ring network between the network switch of its connection; And use optical fiber to connect, therefore can let the transmission speed of monitored data faster, greatly the real-time of the assurance top board disaster alarm of degree.
4. top board disaster monitoring provided by the invention system; Can connect more than one Monitor Sub-Station of Less on the network switch; Can also connect more than one sensor on each Monitor Sub-Station of Less, therefore can monitor wider movement of roof state, reach the better early warning effect of top board disaster.
