Embodiment Construction
[0032] Such as Figure 4 As shown, the automatic control system for coal mine ground production of the present invention is provided with (PLC) respectively at No. 1 transfer point 14, No. 2 transfer point 15, gangue bin 12, buffer coal bunker 23, loading coal bunker 31 stations and the control center Controller, the controller includes a processor module, a long-distance communication module and a short-distance communication module. The communication cable is connected to the remote communication module of the control center,
[0033] The processor module of each station receives the status signal fed back by the sensor device in the production process, sends control signals to the controlled equipment in the production process, receives the control data of the host computer, and exchanges data with the host computer.
[0034] The communication cable connection between the remote communication modules connects the controlled equipment and sensor devices scattered throughout...

The invention discloses an automatic ground production control system for a coal mine. Controllers are respectively arranged at a control center and various stations of a first transfer point 14, a second transfer point 15, a gangue bin 12, a surge coal bunker 23 and a loading coal bunker 31 and comprise processor modules, remote communication modules and short-range communication modules, the short-range communication modules of the various stations are connected with controlled devices and sensor devices by communication cables in local production procedures, the remote communication modules of the various stations are connected with the remote communication modules of the control center by communication cables, the processor modules of the various stations receive state signals fed by the sensor devices in the local production procedures, transmit control signals to the controlled devices in the local production procedures and receive control data of upper computers, and data are exchanged among the processor modules of the stations and the upper computers. The automatic ground production control system has the advantages that monitoring for three relatively independent production portions is unified, accordingly, the reliability of a field bus control mode can be improved, and control strategies can be assuredly reliably executed in severe working environments.
Description
technical field [0001] The invention relates to a control system for industrial equipment, in particular to a control system for coal mine production equipment. Background technique [0002] The surface production process of coal mines can be divided into three relatively independent parts: gangue treatment, raw coal buffer and loading buffer, such as figure 1 As shown, the gangue treatment part mainly includes coal feeder 901A, conveyor belt 902A, conveyor belt 902, conveyor belt 903, conveyor belt 904, electro-hydraulic push rod and other conveyor belts and other auxiliary equipment. The lump gangue in the auxiliary well skip bin 11 is transported to the No. 1 transfer point 14 through the coal feeder 901A through the transport belt 902A, and at the No. 1 transfer point 14 together with the coal preparation plant gangue transported by the transport belt 902, it is transported by the transport belt 903 Transported to No. 2 transfer point 15, then transported to the gangue ...
