The specific meaning of the above terms in the present embodiment can be understood in a specific case by those of ordinary skill in the art.

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

In one embodiment of the present application, the operator may be prompted with logic to indicate the status of the wedge masking system:

after the flow machine equipment is stopped, an operator sets the flow machine equipment to an overhaul mode, and after confirming that the vehicle is safe, the short-circuit choke plug on the flow machine equipment is pulled out to expose the female port. At this time, the first delay on timer starts counting down, the system stops internal signal being set, and the self-locking circuit is broken.

If the first time-delay timer is finished, the operator still does not insert the power plug J1 of the wedge-masking vehicle into the female port of the flow machine device, or the flow machine device does not receive the connection signal YXQ _connect_status for other reasons, for example, when the device is in the remote mode, the ALARM signal agv_alarm_output (24 v positive) is OUTPUT.

If the first time delay on timer finishes counting down, the operator pushes the wedge masking vehicle, the power plug J1 of the wedge masking vehicle is inserted into a female port on the flow machine equipment, at the moment, the power source positive signal AGV_24V+ and the power source negative signal AGV_24V- (24V positive and negative electrodes) are connected, the wedge masking vehicle is electrified, and the connecting signal YXQ _CONNECT_STATUS (24V positive) is transmitted to the flow machine equipment by the wedge masking vehicle.

When the connection signal YXQ _connect_status is received by the streaming apparatus and the streaming apparatus is not in the remote mode, the second delay pass timer starts counting down.

If the position sensor detects that the mask car is in place and receives the confirmation of the operator before the countdown of the second delay on timer is finished, the flow machine equipment receives a ready signal YXQ _lock_status and OUTPUTs a normal operation signal AGV_CHECKSTATUS_OUTPUT.

If the second time delay on timer is finished and the operator is not confirmed, or the in-place detector does not detect that the wedge vehicle is in place, the flow machine equipment cannot receive the ready signal YXQ _lock_status, and at the moment, the flow machine equipment OUTPUTs an ALARM signal AGV_ALARM_OUTPUT. And when an alarm is received, the abnormal state of the wedge masking system is indicated, and operators can carry out maintenance, debugging and the like to remove the abnormality.

After the worker releases the abnormal state, the worker can connect the RESET signal YXQ _reset to the flow machine equipment to release the alarm.

After the operation is completed, the operator removes the wedge masking vehicle and pulls out the power plug J1. If the power plug J1 is removed, the flow machine equipment is in a remote mode, and an ALARM signal AGV_ALARM_OUTPUT is OUTPUT; if the power plug J1 is not in the remote mode after being unplugged, the short-circuit choke plug is reinserted into the female port of the reflow device, then the reflow device is adjusted to a required mode, and system setting is carried out, so that all faults can be reset by the system setting.

The remote mode refers to an automatic operation mode of the flow machine equipment, and is different from a manual mode and a maintenance mode, and in the remote mode, an operator is not allowed to carry out operations such as maintenance on a vehicle.

Specifically, the above-described operating logic may be implemented by the circuit shown in fig. 1:

after the operator inserts the power plug J1 of the masking wedge into the female port on the streamer device, the power positive signal AGV_24V+ and the power negative signal AGV_24V-are used to power the signal interaction module, and then the connection signal YXQ _CONNECT_STATUS is transmitted to the streamer device by the masking wedge.

When the position sensor detects the signal 1AB1 that the anti-wind wedge is in place and confirms that the switch 1AS2 is closed, the streamer device receives the ready signal YXQ _lock_status. Specifically, the position sensors may be provided at both sides of each swing arm 30, but the present application is not limited thereto; the application also does not limit the detection mode of the position sensor, as long as the position of the swing arm can be accurately fed back.

When the streamer device OUTPUTs a normal operation signal agv_checksettatus_output, the second acoustic loop is turned on, specifically, for example, green normally-on light is turned on, and the signal is displayed to an operator through the acoustic-optical device 23.

When the streamer device OUTPUTs an ALARM signal agv_alarm_output, the first relay 1AK1 OUTPUTs a normally open contact, and the first loop is turned on, specifically, for example, the red blinking light 1AH2 and the buzzer 1AH3 are triggered, and displayed to an operator through the acousto-optic device 23. Subsequently, the first relay 1AK1 realizes electrical self-locking through the second relay 1AK2 to continuously emit red blinking light and beeping sound.

When the RESET signal YXQ _reset is connected to the mobile phone, the normally closed contact of the RESET switch 1AS1 is opened, and then each loop where the red blinking lamplight 1AH2 and the buzzer 1AH3 are located is also opened, and the red blinking lamplight 1AH2 and the buzzer sound are stopped.

Through above-mentioned electrical design, can improve equipment degree of automation, ensure personnel's safety.
