[0018] In the embodiment, three coal bunkers 7 are respectively arranged in front of and behind reversible matching bunker conveyor 2, and the conveyor needs to complete remote automatic unloading function on six coal bunkers according to the control signal of the upper computer in the control room.

When the Hall proximity sensor 4 moves to the first coal bunker 7 along with the conveyor, the height of the magnetic steel 6 on the monitoring plate is kept consistent with the height of the first Hall proximity sensor 4, and the PLC control system 8 defines the address of the first Hall proximity sensor 4 as 1; when the Hall proximity sensor 4 moves to the second coal bunker 7, the height of the magnetic steel 6 is kept consistent with the height of the second Hall proximity sensor 4, and the address is defined as 2; when the Hall proximity sensor 4 moves to the third coal bunker 7, the height of the magnetic steel 6 is kept consistent with the height of the third Hall proximity sensor 4, and the address is defined as 3. Similarly, the three Hall proximity sensors 4 installed at the end of reversible matching bunker conveyor 2 are respectively defined as addresses 4, 5 and 6.
