The principle of work of the dust falling in coal mining system that the present embodiment provides is as follows:
Signal trigger element 107 can be connected with the negative pole of the first light-emitting diode 116 of the input end of optic coupler 109, when detecting device 101 detects that transport plane is light condition, signal trigger element 107 produces low level signal, now the negative pole of the first light-emitting diode 116 is low level, the just very high level of the first light-emitting diode 116, therefore, first light-emitting diode 116 is switched on, the NPN type triode 117 also conducting with the conducting of the first light-emitting diode 116 of the mouth of optic coupler 109, by PNP type triode 113, the working current in the coil of relay 110 is amplified again, drive the contact action of relay 110.The open contact 122 of relay 110 is closed, normally closed contact 123 disconnects, now relay 110 exports a make contact signal to controller 103, controller 103 stops after receiving make contact signal providing power supply to switch 104, switch 104 cuts out, switch 104 cuts out and atomising installation 105 and water service 106 is disconnected, and water service 106 stops supplying water to atomising installation 105, and atomising installation 105 stops atomizing de-dusting.
When detecting device 101 detects that transport plane is loading condition, signal trigger element 107 produces high level signal, now the positive pole of the first light-emitting diode 116 and negative pole are high level, first light-emitting diode 116 ends, NPN type triode 117 is in off state, then PNP type triode 113 is also in off condition, no current is by the coil of relay 110, be failure to actuate in the contact of relay 110, the open contact 122 of relay 110 is still for often to open, normally closed contact 123 is still normally closed, now relay 110 exports a break contact signal to controller 103, there is provided power supply to after controller 103 receives break contact signal switch 104, switch 104 is opened, atomising installation 105 and water service 106 conducting, water service 106 supplies water to atomising installation 105, atomising installation 105 starts atomizing de-dusting.
In above-mentioned example, signal trigger element 107, when transport plane is in light condition, produces low level signal, when transport plane is in loading condition, produces high level signal.Certainly, signal trigger element 107 also can be set to when transport plane is in light condition, produce high level signal, first light-emitting diode 116 is ended, thus make relay 110 export break contact signal, and controller 103 stops after receiving break contact signal providing power supply to switch 104, switch 104 cuts out, and atomising installation 105 and water service 106 disconnect.And when transport plane is in loading condition, signal trigger element 107 produces low level signal, make the first light-emitting diode 116 conducting, thus make relay 110 export make contact signal, and controller 103 provides power supply to switch 104 after receiving make contact signal, switch 104 is opened, atomising installation 105 and water service 106 conducting.
