Abstract

The invention belongs to the technical field of remote control communication of a coal mining machine and provides a bidirectional communication remote control device for the coal mining machine. The bidirectional communication remote control device comprises a bidirectional remote controller and a wireless communication isolation module, wherein the bidirectional remote controller is provided with a display unit, a first wireless communication unit, a first data processing unit and a keyboard; the wireless communication isolation module comprises a second wireless communication unit, a second data processing unit, a photoelectric isolation device and a communication port; the bidirectional remote controller is used for giving a remote control instruction and a data refreshing instruction according to information input by the keyboard, and sending the instructions to the wireless communication isolation module; the wireless communication isolation module is used for sending the remote control instruction to an upper computer and obtaining data according to the remote control instruction and the data refreshing instruction, and transmitting the data back to the bidirectional remote controller, and the data is displayed through the display unit. The invention further provides a communication method of the bidirectional communication remote control device. By adopting the bidirectional communication remote control device, bidirectional communication of the remote controller and the upper computer can be realized; the bidirectional communication remote control device can be widely applied to the field of the coal mining machine.

Description

technical field [0001] The invention relates to the technical field of remote control communication of coal shearers, specifically a two-way remote control communication system which can not only realize the wireless remote control operation of the coal shearer, but also realize the wireless readback and display of various data of the coal shearer. Background technique [0002] The shearer is the key core equipment of fully mechanized coal mining face, and its parameter display system is one of the important parts of the shearer system, and it is an intuitive window for miners to understand the performance of the equipment. Knowing the operating parameters of the equipment at any time is the basic guarantee for the safe operation of the coal mining machine, and has a great impact on the safe production of the fully mechanized mining face. [0003] Compared with previous shearers, common shearers are equipped with parameter display devices, which map the operating data of the...

AI Technical Summary

Problems solved by technology

The addition of the display device provides convenience for the production of the miners, but there are still some shortcomings, which become a hidden danger for the safe operation of the coal mining machine and the safe production of the coal mine.

[0004] 1. On the working face with large dip angle and thin coal seam, it is extremely inconvenient for miners to walk inside the support, and it is even more difficult to watch the display window during the fully mechanized mining process, which may easily cause hazards such as falls and bruises;

[0005] 2. On the working face with large mining height, the shearer, scraper machine, and support are relatively large-scale equipment, which makes the support far away from the shearer, and the information on the display device cannot be seen clearly during the fully mechanized mining process. When technical needs must be checked, the shearer must be stopped, which reduces production efficiency;

[0006] 3. The main interface of the traditional display device displays fewer parameters, which makes it impossible for miners to grasp detailed information, which can easily cause equipment damage due to overload
