Programmable upper computer automatic follow-up method

Abstract

The invention discloses a programmable upper computer automatic follow-up method. 1, an upper computer queries the database to obtain an effective automatic follow-up parameter model; 2, judging whether the obtained automatic follow-up parameter model is valid or not, and if it is an effective automatic follow-up parameter model, carrying out the third step; if the parameter model is invalid, theparameter model is edited and created through the graphical interface, and then saved to the database for the third step; 3, the parameter model of the automatic follow-up machine is load by the uppercomputer; 4, the automatic follow-up parameter model is simulated and operated, and whether the running result is correct is checked; if the result is correct, step 5 is carried out and otherwise, the second step is repeated; 5, real-time data of that shearer, the conveyor and the hydraulic support is obtained by the upper computer; 6, the upper computer sends an action control instruction to thebracket controller; 7, whether the action of the hydraulic support is complete is judged; if completed, end; otherwise step 6 is repeated. The invention has the advantages of achieving continuous, safe and efficient mining of the fully mechanized mining face.

Description

technical field [0001] The invention relates to an automatic follow-up method for a host computer, in particular to a programmable automatic follow-up method for a host computer. Background technique [0002] There are five natural disasters of water, fire, gas, coal dust and roof in the fully mechanized mining face of coal mines, which always threaten the life safety and occupational health of coal miners. Therefore, it is an urgent need for coal mine safety production to liberate coal miners from dangerous, harsh and noisy working environments. [0003] The hydraulic support automatic follower technology uses the support controller as the core control unit. By obtaining the cutting process section of the shearer, the coal cutting direction, the traction speed, the cutting height of the left and right drums, the relative position of the shearer and the hydraulic support, Parameters such as the absolute position of the shearer are logically processed by the support controll...

Problems solved by technology

[0004] At present, the support controller is used to complete the automatic follow-up process in the fully mechanized mining face. However, the support controller has limited processing and storage capabilities, and cannot perform complex logic judgments and store a large amount of historical and process data.

At the same time, the auto-following parameters that can be modified by the support controller are limited, and the program is relatively solidified; the geological conditions of different fully mechanized mining faces are quite different, and the geological conditions of the same fully mechanized mining face will also change during the mining process. In the actual situation, adjust the automatic follow-up parameters from time to time, or update the support controller program, and debug and modify. These operations require technicians to go underground to complete, and the efficiency is low.
