A Method of Memory Cutting for Virtual Shearer

Abstract

The invention discloses a memory cutting method of a virtual coal cutter. The memory cutting method comprises the following steps: firstly generating a virtual top and base plate environment in a virtual reality engine Unity3d environment, then paving a virtual scraper conveyor on a virtual base plate as a track for the virtual coal cutter to operate, clicking the button of a virtual control panel to operate the virtual coal cutter, carrying out storage, analysis, processing and reading on operational data by a virtual controller in real time, and thus realizing memory cutting simulation for the coal cutter. According to the method, a new cutting technology algorithm can be quickly tested in different geological environments, and single-machine training of a coal cutter driver and concurrent operation of double persons can be realized.

Description

technical field [0001] The invention relates to a method for realizing memory cutting of a coal shearer in a virtual reality environment, in particular to a method for virtual simulation of the memory cutting technology of a coal shearer in real time under a virtual reality simulation engine Unity3d. Background technique [0002] The fully mechanized coal mining face is very dangerous, the labor intensity of the workers is high, and the automation level is low. Therefore, it is urgent to comprehensively improve the automation level of the fully mechanized mining equipment, and to develop in the direction of intelligence and unmanned. In this process, the shearer The memory truncation technique is particularly important. Since the current coal and rock identification technology has not yet been applied in industry, the method of memory cutting and manual intervention is generally adopted in the fully mechanized mining face as the mainstream mode for long-term operation of the...

Problems solved by technology

The advantage of the first method is that it can truly reflect the results, but it has great limitations: due to the high risk of underground coal mines, all test instruments are required to have explosion-proof, coal safety or intrinsic safety certification, this method is generally applicable to the industry of products Sexual application testing stage, not suitable for general experimental research

The second method, the physical model, is expensive and time-consuming. For a new method to be programmed into the control system, the cycle is longer, and a series of experiments and test systems are prepared. It is difficult to quickly verify the correctness of the method, and even after the method is wrong, The investment in the entire system was in vain, resulting in great economic losses

The third method uses the virtual prototype instead of the physical prototype to test and evaluate the shearer, but the reliability of the research results largely depends on the accuracy of the established mathematical model of the virtual prototype of the coal shearer, but in a memory Cutting technology in R&D phase, still showing potential for speed and accuracy

[0007] However, the defect of the above method is the lack of training and simulation of the shearer memory cutting method
