The utility model has the characteristics of as follows:
(1) the problem of unreliable and lagging of manual monitoring current is fundamentally solved, manual operation is changed into automatic operation, the overload condition of each device can be timely and accurately reflected, advanced control of coal quantity is more accurate, the coal quantity is more uniform, controllability of a production process is stronger, and stability is higher.
(2) Through setting up the dual alarm system of reputation, the degree of distinguishing is higher, and adaptability is stronger. When the loudspeaker of the Beck communication system cannot give an early warning to the fully mechanized coal mining face due to the reasons of faults and the like, the driver of the coal discharger and the coal mining machine can judge whether the equipment is overloaded or not through the light of the alarm lamp, so that the fault tolerance rate of the system is improved.
(3) The traditional manual early warning mode uses a 'buzzing' early warning sound, and the specific overload of which equipment is not achieved, and the command directivity is unclear. The instructions may be confused by a coal cutter driver or a coal cutter, which causes uneven coal quantity control of the front and rear conveyors and affects the stability and continuity of coal production. Through system transformation and application, the voice of the Beck controller is transmitted to the whole fully mechanized coal mining face through a communication loudspeaker, and the command is clear and convenient to execute.
