Embodiment 1

[0039] The embodiment of the present invention provides an automatic coal discharge control system based on video surveillance image recognition, such as figure 1 Shown, comprise support controller 101, hydraulic support 102, rear scraper conveyor 103 and pan-tilt camera 104, wherein:

[0040] The support controller 101 is used to control the action of the hydraulic support 102, by controlling the action of the tail beam and the flashboard of the hydraulic support 102 to control the tail beam to lower the coal; the rear scraper conveyor 103 is arranged on The rear portion of the tail beam of the hydraulic support 102 accepts the coal lowered by the tail beam; the pan-tilt camera 104 is arranged on the tail beam, and it includes a first camera section and a second camera section; The first imaging unit is arranged along the coal conveying direction parallel to the rear scraper conveyor 103, which acquires the coal conveying process image of the rear scraper conveyor; The coal ...

Embodiment 2

[0046] The automatic coal discharge control system based on video surveillance image recognition provided by this embodiment, such as figure 2 As shown, it may also include a two-speed hydraulic valve 105, a travel sensor 106 and an inclination sensor 107. in:

[0047] The two-speed hydraulic valve 105 is arranged on the liquid supply passage of the hydraulic support 2, and the support controller 101 controls the two-speed hydraulic valve 105 to be placed in the slow position, and the hydraulic support 102 starts at the first speed action; when the support controller 101 controls the two-speed hydraulic valve 105 to be placed in the fast position, the hydraulic support 102 operates at a second speed; the second speed is greater than the first speed.

[0048] The stroke sensor 106 is arranged on the plate cylinder and the rear slide cylinder of the hydraulic support 102, and is used to obtain the stroke of the hydraulic support 102 according to the action of the cylinder, and...

Abstract

The invention provides a video monitoring image identification-based automatic coal caving control system. According to the video monitoring image identification-based automatic coal caving control system, a pan-tilt-zoom camera is arranged on a tail beam, and comprises a first shooting part and a second shooting part; the first shooting part is arranged on a coal conveying direction parallel to aback scraper plate conveyer to obtain the coal conveying process images of the back scraper plate conveyer; the second shooting part is arranged in a direction vertical to the coal conveying direction of the back scraper plate conveyer to obtain coal conveying images of the back scraper plate conveyer, and determine the coal conveying amount and coal ash content of coal on the back scraper plateconveyer; the pan-tilt-zoom camera is used for sending the coal conveying process images, the coal conveying amount and coal ash content of coal on the back scraper plate conveyer to an upper computerfor checking by monitors. The video monitoring image identification-based automatic coal caving control system is capable of direction expanding monitoring range of operating personnel to a back coalcaving working face, and avoiding influences of coal and gangue identification and coal thickness change factors caused by geological condition change on coal caving control process.

Description

technical field [0001] The invention relates to the technical field of underground thick coal seam mining automation, in particular to an automatic coal discharge control system based on video surveillance image recognition. Background technique [0002] At present, through the automatic control of the hydraulic support and the shearer, the coal mining face has realized the mining of the working face with few people or even no one. However, due to major technical problems such as coal gangue identification, the coal mining face has not been solved, and the coal is discharged at the rear. There is no effective way to observe, and the change of the top coal cannot be grasped, which makes the transparency of the coal discharge operation process low, the production environment is complicated, and the dust is large. Low efficiency, high cost, low recovery rate and other problems. At the same time, due to improper control during the coal discharge process, it is easy to cause pers...
