Embodiment 1

[0029] Please refer to figure 1 shown. This embodiment provides a shearer cutting curve correction measurement method, including the following steps: control the shearer to perform preset path cutting work, and acquire and record the position information and attitude information of the shearer in real time to form memory data; record The real-time status of the conventional path when the shearer is mining coal, and compare the conventional path with the preset path; if the conventional path is different from the preset path, it will be manually corrected, and finally the shearer will cut according to the memory data.

[0030] In the above-mentioned embodiment, the shearer is controlled to perform the cutting work on the preset path (the preset path is the optimal path, the path with the maximum coal mining efficiency). When the operator controls the shearer to cut, the onboard controller Record the current position information and attitude information of the shearer in time, ...

Embodiment 2

[0044] Please refer to figure 2 shown. An embodiment of the present application provides an electronic device, including: at least one processor 1, at least one memory 2, and a data bus 3; wherein: the processor 1 and the memory 2 communicate with each other through the data bus 3; The program instructions executed by the processor 1, the processor 1 invokes the program instructions to perform the method.

[0045] If the functions are implemented in the form of software function modules and sold or used as independent products, they can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present application is essentially or the part that contributes to the prior art or the part of the technical solution can be embodied in the form of a software product, and the computer software product is stored in a storage medium, including Several instructions are used to make a computer device (which may be a personal computer, a...

Embodiment 3

[0047] An embodiment of the present application provides a non-transitory computer-readable storage medium, the non-transitory computer-readable storage medium stores a computer program, and the computer program enables a computer to execute a method.

[0048] In summary, the first aspect: the embodiment of the present invention provides a shearer cutting curve correction measurement method, including the following steps: controlling the shearer to perform preset path cutting work, and obtaining and recording the position of the shearer in real time Information and attitude information form memory data; record the real-time state of the conventional path of the shearer during coal mining, and compare the conventional path with the preset path; if the conventional path is different from the preset path, manually correct it, and finally the shearer according to Memory data for cutting.

[0049] In the above-mentioned embodiment, the shearer is controlled to perform the cutting w...

Abstract

The invention provides a method for correcting and measuring a mining and cutting curve of a coal mining machine, and relates to the technical field of coal rock cutting. According to the scheme, the method for correcting and measuring the mining and cutting curve of the coal mining machine comprises the following steps of controlling the coal mining machine to cut in a preset path, and obtaining memory data in real time; comparing a conventional path with the preset path; and performing manual correction if the conventional path is different from the preset path, and finally, enabling the coal mining machine to cut according to the memory data. On the premise that the working state of the coal mining machine is normal, frequent lifting of a rocker arm can be avoided, the smoothness of a top plate and a bottom plate is guaranteed, and the coal mining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of coal and rock cutting, in particular to a method for correcting and measuring the cutting curve of a coal shearer. Background technique [0002] The 2017 National Energy Consumption Report pointed out that the total consumption of coal energy resources in the country in 2017 accounted for 60.4% (4.49 billion tons) of the total energy consumption in the country. It can be seen that coal consumption is still the main force of my country's national energy consumption. However, the underground coal resources have not yet been automated and intelligently mined. The coal mining efficiency of the shearer and the service life of the shearer are the most prominent problems. [0003] At present, the coal mining method of coal shearers on the market is single, and it cannot identify the abnormal state of the drum when cutting rocks, and cannot make adaptive adjustments to the traction speed and drum height, and can...
