Fig. 1 is a schematic structural diagram of a boarding bridge control device according to an embodiment of the present invention, the control device is applicable to a scenario where different types of safety boots are used in combination, referring to fig. 1, the boarding bridge control device includes a safety boot type selection module 110, a safety boot detection module 120, a first control module 130, a second control module 140, and a descent control module 150, the safety boot detection module 110 is configured to detect an action state of a safety boot and output an action signal from an output end thereof, and the safety boot type selection module 120 is configured to determine an access type of the safety boot according to a trigger signal; a first input end A1 of the first control module 130 is connected with the output end of the safety boot type selection module 110, a second input end A2 of the first control module 130 is connected with the output end of the safety boot detection module 120, a first input end B1 of the second control module 140 is connected with the output end of the safety boot type selection module 110, and a second input end B2 of the second control module 140 is connected with the output end of the safety boot detection module 120; the first control module 130 and the second control module 140 are configured to: when the first type of safety boot is connected, the first control module 130 is configured to output a first control signal CS1 when receiving the action signal; when a second type of safety boot is connected, the second control module 140 is configured to output a second control signal CS2 when receiving the action signal; the input end of the descent control module 150 is connected to the output end A3 of the first control module 130 and the output end B3 of the second control module 140, the output end of the descent control module 150 is connected to the boarding bridge 160, and the descent control module 150 is configured to control the boarding bridge 160 to descend according to the first control signal CS1 or the second control signal CS2.
Specifically, in the airport pickup process, the safety shoe is usually located below the opened cabin door, and when the airplane cabin door descends, the safety shoe is triggered, and the safety shoe detection module 120 can detect the action state of the safety shoe in real time, so as to output a corresponding action signal from its own output end, so as to serve as a basis for adjusting the descending height of the boarding bridge 160. However, the action signals generated by different types of safety boots in the same action state are different, so that the control of the subsequent boarding bridge 160 cannot work normally.
In this embodiment, the boarding bridge control apparatus is provided with a safety shoe type selection module 110 for judging the type of the selected safety shoe according to the trigger signal. Wherein different trigger signals correspond to different types of safety boots. For example, if the safety boot type selection module 110 determines that the accessed safety boot is a first type of safety boot, a first sub-signal is output and is respectively output to the first input terminal A1 of the first control module 130 and the first input terminal B1 of the second control module 140; if the safety boot type selection module 110 determines that the accessed safety boot is a second type of safety boot, a second sub-signal is output and is respectively output to the first input end A1 of the first control module 130 and the first input end B1 of the second control module 140. Meanwhile, the safety boot detecting module 120 inputs the action signals generated by the safety boot to the second input terminal A2 of the first control module 130 and the second input terminal B2 of the second control module 140, respectively. Here, the first type of safety boot may be a domestic safety boot, and the second type of safety boot may be an import safety boot.
The output terminal A3 of the first control module 130 and the output terminal B3 of the second control module 140 are both connected to an input terminal of the droop control module 150 to send control signals to the droop control module 150. In this embodiment, the first control module 130 may control the motion signal output by the first type of safety boot, and the second control module 140 may control the motion signal output by the second type of safety boot. For example, when the security boot type selection module 110 determines that the accessed security boot is a first type of security boot, the security boot type selection module 110 outputs a first sub-signal; when the safety boot detection module 120 detects the safety boot action, an action signal is output; the first control module 130 outputs a first control signal CS1 according to the first sub-signal and the motion signal, and the descending control module 150 controls the boarding bridge 160 to descend according to the first control signal CS1. When the safety boot type selection module 110 determines that the accessed safety boot is a second type of safety boot, the safety boot type selection module 110 outputs a second sub-signal; when the safety boot detection module 120 detects the safety boot action, an action signal is output; the second control module 140 outputs a second control signal CS2 according to the second sub-signal and the motion signal, and the descending control module 150 controls the boarding bridge 160 to descend according to the second control signal CS2.
The embodiment of the utility model provides a boarding bridge controlling means, through setting up the type that safety boots type selection module detected the safety boots that insert, safety boots type selection module exports corresponding sub-signal after the type of confirming safety boots, and first control module and second control module combine corresponding sub-signal to control the boarding bridge after receiving the action signal of safety boots detection module output. The first control module is used for outputting a first control signal when the safety boots of the first type are accessed so as to control the boarding bridge to descend through the descending control module, and the second control module is used for outputting a second control signal when the safety boots of the second type are accessed so as to control the boarding bridge to descend through the descending control module. Because the signals output by the safety boots of different types are different, the scheme controls the output of the safety boots of different types respectively through the first control module and the second control module so as to realize that the boarding bridge control device can be compatible with the safety boots of different types.
Optionally, fig. 2 is a schematic structural diagram of another boarding bridge control device according to an embodiment of the present invention, and with reference to fig. 2, on the basis of the foregoing technical solution, a communication end of the first control module 130 is in communication connection with a communication end of the second control module 140, so that the first control module 130 and the second control module 140 can cooperate with each other. The first control module 130 is further configured to transmit a first check signal JS1 to the second control module 140 when the second control module 140 outputs the second control signal CS2; the second control module 140 is further configured to transmit a second check signal JS2 to the first control module 130 when the first control module 130 outputs the first control signal CS1.

Under the condition that both the first control module 130 and the second control module 140 can be normally started, if the safety shoe type selection module 110 determines that the accessed safety shoe is the first type of safety shoe, the first control module 130 is configured to perform output control, and at the same time, the second control module 140 also responds to the output signal of the safety shoe type selection module 110 and sends a second check signal JS2 to the first control module 130 to check whether the input types of the safety shoes received by the two control modules are consistent. If the first control signal CS1 is identical to the second control signal CS, the first control module 130 outputs the first control signal CS1 in response to the first sub-signal output by the safety shoe type selection module 110 and the action signal output by the safety shoe detection module 120.
If the safety shoe type selection module 110 determines that the accessed safety shoe is the second type of safety shoe, the second control module 140 is configured to perform output control, and the first control module 130 also verifies the input of the safety shoe in response to the output signal of the safety shoe type selection module 110 and sends a first verification signal JS1 to the second control module 130 to verify whether the input types of the safety shoes received by the two control modules are consistent. If the signals are consistent, the second control module 140 outputs the second control signal CS2 in response to the second sub-signal output by the safety shoe type selection module 110 and the action signal output by the safety shoe detection module 120.
Alternatively, if not, the safety boot type selection module may be controlled to re-detect the type of the safety boot.
Optionally, if the first control module 130 and the second control module 140 detect that one of the two control modules cannot be normally started in the mutual inspection process, the normally started control module completes all subsequent control operations, so that redundancy of the system is increased, and stable operation of the control function can be continuously guaranteed when one of the two control modules fails. That is, when the first control module 130 fails and stops operating, the second control module 140 outputs the first control signal CS1 or the second control signal CS2 after receiving the operation signal. Alternatively, when the second control module 140 fails and stops operating, the first control module 130 outputs the first control signal CS1 or the second control signal CS2 after receiving the operation signal.
Optionally, in this embodiment, the first control module 130 and the second control module 140 may both be MCUs.
