Description of drawings
Accompanying drawing 1 is the catenation principle block diagram of roof pressure detection system according to the invention;
Accompanying drawing 2 is the sketch map of pressure broken line graph of the present invention;
Accompanying drawing 3 is the sketch map of pressure block diagram of the present invention.
The specific embodiment
Referring to accompanying drawing 1, it has described a preferred embodiment based on coal-face roof pressure detection system (it comprises hydraulic support electrohydraulic control system) in the roof pressure figure display analysis method of coal-face propelling degree according to the invention.Comprise hydraulic support, bracket controller, pressure sensor, stroke sensor, signal adapter and monitoring host computer.Coal-face has a plurality of hydraulic supports to form along the arrangement of work plane order; Be used for supporting the coal work top board; Wherein all be provided with a bracket controller, a stroke sensor and at least one pressure sensor on every hydraulic support; Each pressure sensor, stroke sensor are electrically connected through the bracket controller on connector and the same hydraulic support respectively, and each bracket controller is connected in series through connector, are provided with a signal adapter at face end; One end is connected with a bracket controller through connector, and the other end is connected with the monitoring host computer of crossheading through connector.Each bracket controller is except that the basic function action of controlling this; Also gather pressure sensor and stroke sensor data on this; After working surface hydraulic support top plate supporting pressure data in collecting pressure sensor and the hydraulic support in the stroke sensor were passed run-length data, each bracket controller was encoded to above-mentioned data, adds the information of hydraulic support therein; Pressure and run-length data with to each hydraulic support are distinguished; Then, each bracket controller is the above-mentioned signal adapter that sends through coded data, signal adapter with above-mentioned data transaction be the discernible signal of monitoring host computer and with this signal forwarding to monitoring host computer.
Data Dynamic monitoring face propelling degree and face roof pressure that monitoring host computer sends according to signal adapter; Analyze cyclically-varying situation through DAS or other attainable mode along with the propulsioning face roof pressure of work plane; And draw pressure broken line graph or pressure block diagram according to the cyclically-varying situation of face roof pressure; Through pressure broken line graph or pressure block diagram judgment task face top plate supporting pressure trend, the top plate supporting pressure of top plate supporting pressure changing, the identical or close propelling degree of different hydraulic support etc. when different propellings are spent like same hydraulic support.
Like the working pressure broken line graph, in the operating process of reality, coal-face is after coal-winning machine whenever cuts a cutter; On monitoring host computer, will receive the passing stroke and the top plate supporting pressure data of full face hydraulic support; Pass stroke average and top plate supporting pressure mean values through calculating work plane, a new coordinate point on the picture of monitoring host computer, occurs, the abscissa of this point is that work plane is passed stroke average; Ordinate is a face roof abutment pressure average; This coordinate point and a last coordinate point coupled together with straight line form a broken line,, just formed a pressure broken line graph with the advance of the face like this along with the passing of work plane.When this curve exceeds the picture scope, the broken line graph of progress picture is at first partly shifted out picture, keep latest data can be retained on the picture always.The example of pressure broken line graph is referring to accompanying drawing 2.
Like the working pressure block diagram, coal-face will be received the passing stroke and the top plate supporting pressure data of full face hydraulic support on monitoring host computer after coal-winning machine whenever cuts a cutter, and each hydraulic support uses a post to represent; Have how many hydraulic supports just in block diagram, to place how many posts, post is arranged in order by the physical location of hydraulic support, and promptly its abscissa is the sequence of positions of expression hydraulic support; Its ordinate is represented working surface hydraulic support passing stroke, and it is longer to pass big its post of hydraulic support of stroke, and it is shorter to pass little its post of hydraulic support of stroke; The size of the top plate supporting pressure of each hydraulic support representes that through the different colours or the shade of each post pressure is big more, and color is dark more; As use the black and white colour system to represent, and the hydraulic support that top plate supporting is bigger, the color of its post will be more black; And the less hydraulic support of top plate supporting, the color of its post will be whiter, distinguish with this; As use various colors, and the bigger hydraulic support of top plate supporting then, the color of its post is used the expression of dark system; And the less hydraulic support of top plate supporting, the color of its post is used the expression of light color system, to form pressure size expression intuitively; Like this, along with the propelling of work plane has formed one by a plurality of different colours and color of the same race and the pressure block diagram that the post of the different colours depth constitutes.Like this along with the passing of work plane; Just formed one with advance of the face shape; And can observe propelling pressure changes in distribution situation along with entire working surface; Observe every hydraulic support along with advance of the face pressure changing, help analyzing roof pressure situation of change and the Changing Pattern of hydraulic support in whole coal cutting process.The example of pressure block diagram is referring to accompanying drawing 3.
The above; Be merely the preferable specific embodiment of patent of the present invention; But the protection domain of patent of the present invention is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that patent of the present invention discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of patent of the present invention.
