Description

Technical Field

[0001] The present invention relates to the field of coal mining equipment communication, and in particular to an intelligent coal mining machine external remote setting system and method. Background Art

[0002] Coal mining machine is the main equipment in the process of coal mining. The new intelligent coal mining machine currently used has the functions of memory coal cutting and intelligent mining of process sections. In the actual mining process, the corresponding technical parameters are set according to the different conditions of each working face. With the change of the working face, the technical parameters need to be changed at any time according to the actual situation. The coal mining machine mainly uses the following three methods to change the technical parameters: 1. Use the human-machine interface of the coal mining machine equipment to interact with the PLC to set the intelligent parameters of the coal mining machine. The main disadvantage of this method is that it is necessary to stop the machine to open the coal mining machine cover. The coal dust is relatively large during work and it is not suitable to open the cover; 2. Through the upper computer communication setting, this method is far away from the coal mining machine. The configuration requires the upper computer, explosion-proof display, power supply, intrinsically safe keyboard, etc., which is large in size and cost, and the function is repeated with the control center. In addition, some manufacturers put the intelligent program of the coal mining machine in the upper computer. In this way, due to the long distance, the control instructions and the return data are more likely to be delayed, and the coal mining machine control is prone to large errors. 3. It is set up through a computer or a specially made single-chip microcomputer. Since it is a fixed device, it cannot be carried during normal work. Sometimes it needs to be taken separately when needed. Moreover, such equipment will not be equipped with multiple coal mining equipment. If problems occur and need to be changed, the fault tolerance rate is low and it cannot meet the intelligent requirements of unmanned work. Summary of the invention
