Reform transform current gas circuit: the ore feeding pneumatic flat gate mainly sends ore materials in a feeding hopper to an ore feeding belt through the pneumatic flat gate, and the pneumatic gate valve consists of two paths of air inlet and two paths of air exhaust, as shown in figure 2. When the valve is opened, air is fed into one side of the cylinder to push the gate valve away from the other side for exhausting; when the gate valve is closed, the air is fed from the exhaust side to push the gate back, and the air is discharged from the air inlet side. At present, the gas circuit cannot be automatically controlled, manual operation is needed, and therefore, in order to achieve automatic control, the gas circuit needs to be firstly modified. Modifying the ore feeding gas circuit, breaking the existing main gas circuit to install two tee joints, respectively installing two new pipes, positioning the new valve opening side and valve closing side, and respectively installing a 1-inch electromagnetic valve on each of the two new pipes to close the control gas circuit when the electromagnetic valve is not powered; then, the old valve opening side and the old valve closing side are broken, a tee joint is respectively installed, and the two new pipes are introduced; two sextuple electromagnetic valves are respectively arranged at the two exhaust ends; when the valve is opened, exhausting air; similarly, when the valve is closed, the other valve exhausts; two proximity switches are needed for opening and closing the valve, so that the valve is ensured to be in place; the purpose of installing the tee joint on the original gas circuit is to keep a manual mode.

When the control system operation picture displays that the gate is closed, the gate opening operation is carried out through the upper operation picture of the control system, an air inlet electromagnetic valve installed on an air path is electrified, a valve is opened, air is fed into a pneumatic flat gate, a gate plate is pushed by air pressure, proximity switches are installed at the positions where the gate is opened to the proper position and closed to the proper position, the proximity switch is triggered when the gate is opened, and the gate opening operation is stopped in a linkage manner; the gate is opened. When the control system operation picture shows that the gate is opened, the gate closing operation is carried out through the upper part of the control system, the exhaust electromagnetic valve arranged on the gas circuit is electrified, the pneumatic flat gate exhausts, when the gate closing in place is triggered by the proximity switch, the gate closing operation is stopped in a linkage manner, and the gate is closed. The camera is installed in the mine workshop, the camera and the video machine are in transmission communication through the wireless video module, and the video machine is arranged in the control room.
