Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present invention, as the achievement, functional features, and advantages of the present invention are further described with reference to the embodiments, with reference to the accompanying drawings.
The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a method for adjusting signal transmission of a door in a door according to an embodiment of the present invention includes:
s1: identifying an opening and closing state of a door in a preset door, and switching the color of a preset signal lamp based on the opening and closing state, wherein the opening and closing state specifically comprises opening or closing of a small door;
s2: judging whether the color of the signal lamp is matched with the power-on color of the door in the preset door or not;
s3: if yes, a preset transmitting end is applied to transmit a corresponding signal, a preset relay is activated within a preset period based on the signal received by a preset receiving end, and the power supply is output by the relay to enable the door-in-door to execute an instruction corresponding to the signal, so that the self-adaptive control of the single opening and closing state of the door-in-door is completed;
S4: judging whether the door in the door has an open-close working state at least twice or more in a preset period;
s5: if not, detecting the electric quantity state of the door in the door, interrupting the electric connection of the transmitting end and the receiving end to the door in the door for a short time based on the suspension of the opening and closing working state, and simultaneously controlling the transmitting end to output a power-off signal to the receiving end so as to disconnect the power supply output of the relay.
In this embodiment, the system switches the conversion colors of the signal lamps preset on the door based on different opening and closing states by identifying the preset opening and closing states of the door in the door, and then judges whether the conversion colors match the preset power-on colors or not so as to execute the corresponding steps; for example, when the system determines that the converted color cannot match the preset power-on color, the system considers that the conversion color of the signal lamp can be possibly caused by inaccurate state detection of the magnetic induction switch, the position and the sensitivity of the sensor can be calibrated, meanwhile, the color perception of the sensor and the signal lamp can be influenced by the change of the ambient illumination, if the ambient illumination condition changes, the threshold value of the sensor needs to be adjusted to adapt to different illumination conditions, so that the converted color of the signal lamp can be matched with the preset power-on color, and the situation that the relay cannot provide power output due to color mismatch is avoided; for example, when the system determines that the conversion color can be matched with the preset power-on color, the system sends out a small door operation signal by using a preset transmitting port of the door in the door, meanwhile, the preset receiving end receives the small door operation signal, the receiving end needs to activate a preset relay within a preset time period, otherwise, the relay needs to re-receive the small door operation signal after the preset time period passes to output a power supply, the power supply is output into the small door of the door in the door through the relay, so that the small door has temporary power for executing instructions, the door in the door can execute the signal instruction received by the signal instruction, and the self-adaptive instruction control under the single opening and closing state of the door in the door is completed; then the system judges whether the door in the door is continuously in a working state or not so as to execute corresponding steps; for example, when the system determines that the door in the door is in a continuous working state at present, the system keeps the continuous working state of the door in the door based on the fact that the door in the door has the electric quantity capable of supporting the door in the door to finish executing instructions, until the door in the door finishes all instructions to be executed or the system recognizes that the door in the door has the condition of insufficient electric quantity, the system stops receiving signal instructions of the door in the door, and after all instructions to be executed are executed, the door in the door is subjected to short power-off protection and battery replacement, so that the relay is prevented from accidentally outputting power to the door in the door during the battery replacement, accidental occurrence of the electric appliance is avoided, and the door in the door can be made to enter the working state again after the replacement is completed; for example, when the system determines that the door in the door is not continuously in a working state, the system detects the residual electric quantity of the door in the door, and after the door in the door stops working state, the electric connection of the transmitting end and the receiving end to the door in the door is interrupted for a short time, so that the door in the door can be in a closed state in a period of time when the small door is in a non-working state, the door in the door is in a standby state with the lowest power consumption, and when the system detects that the electric quantity of the door in the door is insufficient, a power-off signal is output to the receiving end through the transmitting end, so that the relay cuts off the power supply output, the door in the door is replaced by a battery in time, and the working efficiency of the door in the door is prevented from being influenced.
The device is triggered by the magnetic induction switch, when the small door is closed, the switch is closed, the door transmitting end device in the trigger door transmits a signal to the receiving end device, after the receiving device receives the signal, the receiving device returns to the transmitting device after processing is finished, and the transmitting device can enter a dormant state; when the small door is opened, the magnetic switch is opened, the wireless device is triggered to send a small door opening signal to the receiving device, the receiving device replies a signal to the transmitting device after receiving the signal, and the transmitting device can enter a periodic dormancy state; actively sending a query state signal when the receiving device is powered on, closing a default small door switch if no reply of the transmitting device is received within 3 seconds, and updating the state of the receiving device according to the reply of the transmitting device if the reply signal is received; through the workflow, the door-in-door equipment can realize low-power consumption standby for the maximum time because the small door is in the closed state for more than 95 percent of time.
In this embodiment, after step S3 of activating the preset relay in the preset period of time based on the signal received by the preset receiving end by applying the corresponding signal sent by the preset transmitting end, the method further includes:
s301: synchronizing pre-collected early warning signals to the door-in-door, wherein the early warning signals include, but are not limited to, fire signals, earthquake signals and toxic gas disasters;
S302: judging whether the early warning signal is matched with a hidden danger instruction preset in the door;
s303: if yes, the transmitting end is overridden to transmit the early warning signal to the receiving end, and the operation of the relay is interrupted through the receiving end.
In this embodiment, the system synchronizes the pre-collected early warning signal into the door-in-door, and then the system judges whether the early warning signal can generate potential safety hazard to the door-in-door or not, so as to execute the corresponding steps; for example, when the system judges that the early warning signal is a toxic gas disaster, potential safety hazards cannot be generated to the door in the door, the system can adjust the signal lamp of the door in the door to be white with special color, so that people in the door in the way know that the disaster occurring in the current environment cannot have potential hazards to the operation of the door in the door, and the door in the door can be used for escaping or refuge; for example, when the system determines that the early warning signal is a fire signal, the fire can generate potential safety hazard to the door in the door, at this time, the system can send the signal without a transmitting end and directly transmit the early warning signal to a receiving end, so that the receiving end sends a power-off instruction to a relay, and the power-off protection instruction is executed for the door in the door, thereby avoiding people from escaping or taking refuge by using the door in the door under the current disaster environment and avoiding accidents caused by the operation of the door in the door.
In this embodiment, the step S3 of performing adaptive control of the single open/close state of the door in the door by using the relay output power to enable the door in the door to execute the instruction corresponding to the signal further includes:
s31: receiving a secondary signal sent by the transmitting end based on the signal instruction being executed;
s32: judging whether the secondary signal conflicts with the signal instruction being executed or not;
s33: if yes, correcting the current instruction to be executed of the door in the door based on the priority of different signal instructions, wherein the different signal instructions specifically comprise state inquiry, a timing switch and a request switch.
In this embodiment, the system receives and interprets the secondary signal sent again by the transmitting end based on the signal instruction being executed by the current gate, and then determines whether the secondary signal collides with the signal instruction being executed, so as to execute the corresponding step; for example, when the system determines that the secondary signal does not collide with the signal instruction being executed, the system executes the signal instruction being executed together with the signal instruction corresponding to the secondary signal, for example, one signal instruction indicates "open door", the other signal instruction indicates "start alarm", and simultaneously, the two signals are sent to realize the operations of opening door and starting alarm, the working state of the door in the door is not influenced during the operation, and the alarm effect can be also achieved; for example, when the system determines that the secondary signal collides with the signal command being executed, the system corrects the current command to be executed of the door based on the priority of different signal commands, such as the command a (open door) and the command B (close door) are received simultaneously during the closing of the door.
In this embodiment, in step S5 of detecting the state of charge of the door in the door, the method further includes:
s51: identifying the color rendering degree of the signal lamp, and acquiring the residual electric quantity of the signal lamp based on the color rendering degree;
s52: judging whether the residual electric quantity is larger than a preset available electric quantity value or not;
s53: if not, the signal lamp is flashed through the transmitting end to generate a replacement battery prompt for the signal lamp, and the flashing times of the signal lamp are correspondingly adjusted based on the consumption duration of the residual electric quantity.
In this embodiment, the system obtains the residual electric quantity of the LED signal lamp according to the color rendering degrees of different degrees by identifying the color rendering degrees of the LED signal lamp, and then judges whether the residual electric quantity is greater than the available electric quantity value in the daily working state of the door in the door so as to execute the corresponding steps; for example, when the system determines that the remaining power can be greater than the available power value, the system keeps monitoring the remaining power of the signal lamp and continues to use the signal lamp to operate with the door in the door until the power of the signal lamp cannot support the signal lamp to continuously emit lights with different colors, i.e. the remaining power is insufficient to continue to operate; for example, when the system determines that the remaining power is not greater than the available power value, the system flashes the LED signal lamp through the transmitting end to generate a power shortage prompt that the signal lamp needs to replace a battery, the signal lamp still maintains color presentation of different instructions during flashing, but the power shortage cannot be continuously presented or the presentation duration is shorter, so that the situation that the signal lamp still maintains high-power-consumption work to enable the power of the signal lamp to be quickly reduced due to the fact that the power of the signal lamp is still low is avoided, the presentation duration of the signal lamp can be reduced linearly, the signal lamp can be kept for enough operation duration to complete the presentation of the remaining color until a worker performs battery replacement when the power of the signal lamp is low, and when the remaining power of the signal lamp is less and less, the number of flashes of the signal lamp is more and more frequent at the moment, namely, the worker is reminded of immediately stopping door operation and performing battery replacement for the signal lamp, and the door in the door cannot normally execute signal instructions through the signal lamp is avoided.
In this embodiment, before step S5 of simultaneously controlling the transmitting end to output a power-off signal to the receiving end and disconnecting the power output of the relay, the method further includes:
s501: stopping the door-in-door from receiving the signal instruction and stopping the instruction execution of the door-in-door;
s502: judging whether a door in the door has a residual instruction to be executed or not;
s503: if not, closing the door-in-door, disconnecting the power supply, and replacing the battery of the door-in-door.
In this embodiment, the system cuts off the gate in the gate to receive any signal instruction before cutting off the power output of the relay, and simultaneously stops the gate in the gate to continue to execute the signal instruction, and then determines whether the gate in the gate has a residual instruction to be executed, so as to execute the corresponding step; for example, when the system determines that the door in the door still has residual instructions to be executed, the system sets a warning mechanism to inform a user or an operator of insufficient battery power in advance when the battery power is nearly exhausted, and sets an instruction cache in a control logic of the door in the door to store the instructions to be executed, so that even if the battery power is exhausted, the instructions to be executed can be temporarily stored in the cache, and the instructions to be executed can still be normally executed after the battery replacement is completed; for example, when the system determines that there are no remaining instructions to be executed on the door-in-door, the system ensures that the door-in-door system is in a closed state before battery replacement, thereby preventing any accidental operation or interference, and requiring a power-off operation before battery replacement is performed, ensuring that no electric shock is suffered when the battery is replaced.
In this embodiment, the step S1 of identifying the open-close state of the door in the preset door and switching the color of the preset signal lamp based on the open-close state includes:
s11: the current running color of the signal lamp is obtained by sending a query signal through the transmitting end;
s12: judging whether the running color accords with a preset working color or not;
s13: if not, a communication bridge is added between the door-in-door and the signal lamp, so that the communication connection between the door-in-door and the signal lamp is enhanced.
In this embodiment, the system sends a query signal through the transmitting end to obtain the color content currently presented by the signal lamp, and then the system judges whether the color content currently presented accords with the preset working color of the door in the door or not, so as to execute the corresponding steps; for example, when the system determines that the currently presented color content can meet the preset working color of the door in the door, the system considers that the door in the door and the signal lamp can play a linkage role at present, for example, the color of the signal lamp corresponding to the door opening instruction set in the door is green, as long as the color presented by the signal lamp is green, a person needing to see the corresponding signal lamp prompt through the door in the door enters the door in the door, for example, the color of the signal lamp corresponding to the door closing instruction set in the door is red, and as long as the color presented by the signal lamp is red, the person needing to see the corresponding signal lamp prompt through the door in the door needs to wait for the instruction before entering the door in the door; for example, when the system determines that the currently presented color content cannot conform to the preset working color of the door-in-door, the system considers that the door-in-door cannot generate linkage action with the signal lamp at present, the system adds a communication bridge between the door-in-door and the signal lamp, strengthens the communication connection established between the door-in-door and the signal lamp, ensures that the transmission distance and the signal strength of the signal lamp are enough, and the door-in-door can receive the signal, if necessary, can also adjust the position of the signal lamp or increase a signal amplifier, so that the door-in-door and the signal lamp can play the linkage action, and the condition that a person waiting to pass through cannot know the working state of the door-in-door at present through the signal lamp is avoided.
In this embodiment, before step S1 of identifying the open-close state of the door in the preset door and switching the color of the preset signal lamp based on the open-close state, the method further includes:
s101: based on a preset magnetic induction switch and an LED signal lamp, generating an execution instruction of the door-in-door by applying a pre-recorded programming code;

s103: if so, controlling the on-off of an LED signal lamp connected to the GPIO pin by setting the output state of the GPIO pin, and detecting the state of a gate-in-gate device connected to the GPIO pin by reading the input state of the GPIO pin.
In the embodiment, the system generates the execution instructions of the door in the door by applying the pre-recorded programming codes based on the magnetic induction switch and the LED signal lamp pre-arranged in the door, and then the system judges whether the execution instructions can interact through the GPIO pin pre-arranged in the door so as to execute the corresponding steps; for example, when the system determines that the execution instructions cannot interact through the GPIO pins provided in advance, the system needs to ensure that the connection of the GPIO pins is correct, and ensure that the cables and the connections between the door and the related devices are inserted into correct pin positions by checking the cables and the connections between the door and the related devices, and meanwhile, if the GPIO pins are used for configuration, for example, an input or output mode is selected, so that the configuration of the pins is matched with the system requirements, the incorrect pin configuration can cause the incapacity of interaction, and finally, the electrical parameters (voltage, current and the like) of the GPIO pins are matched with the requirements of the door and the related devices in the door, and the incorrect electrical parameters can cause communication failure; for example, when the system determines that the execution instructions can interact through the GPIO pins provided in advance, the system can identify the opening and closing states of the doors in the doors through programming, and switch the colors of the signal lamps according to the states.
Note that specific examples of executing code using python are as follows:

import RPi.GPIO as GPIO
import time
# set GPIO pin
GPIO pin connected with sensor_pin=17# magnetic induction switch

if door_status= gpio.low: # gate off state
print ('door closed, LED turns green')
GPIO. Output (led_pin, GPIO. HIGH) # Green LED
else: # door open status
print ('door open, LED turns red')
GPIO. Output (led_pin, GPIO. Low) # Red LED
Sleep (1) # time delay 1 second continue detection
except KeyboardInterrupt:

print ('program has ended')
if __name__ == "__main__":
main()
The above code assumes that the magnetically sensitive switch and LED signal light are connected to the GPIO pin, and the comments in the code have explained the function of each step, and the system can be adapted as appropriate to the specific hardware and configuration required.
Referring to fig. 2, a signal transmission adjusting system for a door in a door according to an embodiment of the present invention includes:
the switching module 10 is configured to identify an open-close state of a door in a preset door, and switch colors of preset signal lamps based on the open-close state, where the open-close state specifically includes opening or closing a small door;
the judging module 20 is configured to judge whether the color of the signal lamp matches the power-on color of the door in the preset door;
the execution module 30 is configured to, if yes, apply a preset transmitting end to send a corresponding signal, activate a preset relay in a preset period based on the signal received by a preset receiving end, and enable the door-in-door to execute an instruction corresponding to the signal through the relay output power supply, so as to complete adaptive control of a single open-close state of the door-in-door;
a second judging module 40, configured to judge whether the door in the door has an open-close working state at least twice or more within a preset period of time;
and the second execution module 50 is configured to detect an electric quantity state of the door in the door if not, interrupt the electric connection of the transmitting end and the receiving end to the door in the door for a short time based on the suspension of the open-close working state, and simultaneously control the transmitting end to output a power-off signal to the receiving end, and disconnect the power output of the relay.
In this embodiment, the switching module 10 switches the conversion colors of the signal lamps on the door in advance based on different opening and closing states by identifying the current opening and closing states of the door in advance, and then the judging module 20 judges whether the conversion colors match the preset power-on colors or not to execute the corresponding steps; for example, when the system determines that the converted color cannot match the preset power-on color, the system considers that the conversion color of the signal lamp can be possibly caused by inaccurate state detection of the magnetic induction switch, the position and the sensitivity of the sensor can be calibrated, meanwhile, the color perception of the sensor and the signal lamp can be influenced by the change of the ambient illumination, if the ambient illumination condition changes, the threshold value of the sensor needs to be adjusted to adapt to different illumination conditions, so that the converted color of the signal lamp can be matched with the preset power-on color, and the situation that the relay cannot provide power output due to color mismatch is avoided; for example, when the system determines that the converted color can match the preset power-on color, the execution module 30 sends out a small door operation signal by using a preset transmitting port of the door, meanwhile, the preset receiving end receives the small door operation signal, the receiving end needs to activate a preset relay within a preset period, otherwise, the relay needs to re-receive the small door operation signal after the preset period passes to output power, the relay outputs the power into the small door of the door, so that the small door has temporary power for executing instructions, and at the moment, the door in the door can execute a signal instruction received by the signal end, and the self-adaptive instruction control under the single opening and closing state of the door in the door is completed; the second judging module 40 judges whether the door in the door is in a working state continuously so as to execute the corresponding steps; for example, when the system determines that the door in the door is in a continuous working state at present, the system keeps the continuous working state of the door in the door based on the fact that the door in the door has the electric quantity capable of supporting the door in the door to finish executing instructions, until the door in the door finishes all instructions to be executed or the system recognizes that the door in the door has the condition of insufficient electric quantity, the system stops receiving signal instructions of the door in the door, and after all instructions to be executed are executed, the door in the door is subjected to short power-off protection and battery replacement, so that the relay is prevented from accidentally outputting power to the door in the door during the battery replacement, accidental occurrence of the electric appliance is avoided, and the door in the door can be made to enter the working state again after the replacement is completed; for example, when the system determines that the door-in-door is not continuously in the working state, the second execution module 50 detects the residual electric quantity of the door-in-door, and after the door-in-door stops working state, the electric connection of the transmitting end and the receiving end to the door-in-door is interrupted for a short time, so that the door-in-door can be in a closed state under the period of the small door in the non-working state, and the door-in-door is in the standby state with the lowest power consumption.
In this embodiment, further comprising:
the synchronization module is used for synchronizing pre-collected early warning signals to the door-in-door, wherein the early warning signals comprise but are not limited to fire signals, earthquake signals and toxic gas disasters;
the third judging module is used for judging whether the early warning signal is matched with a hidden danger instruction preset in the door or not;
and the third execution module is used for sending the early warning signal to the receiving end by exceeding the transmitting end if yes, and interrupting the operation of the relay through the receiving end.
In this embodiment, the system synchronizes the pre-collected early warning signal into the door-in-door, and then the system judges whether the early warning signal can generate potential safety hazard to the door-in-door or not, so as to execute the corresponding steps; for example, when the system judges that the early warning signal is a toxic gas disaster, potential safety hazards cannot be generated to the door in the door, the system can adjust the signal lamp of the door in the door to be white with special color, so that people in the door in the way know that the disaster occurring in the current environment cannot have potential hazards to the operation of the door in the door, and the door in the door can be used for escaping or refuge; for example, when the system determines that the early warning signal is a fire signal, the fire can generate potential safety hazard to the door in the door, at this time, the system can send the signal without a transmitting end and directly transmit the early warning signal to a receiving end, so that the receiving end sends a power-off instruction to a relay, and the power-off protection instruction is executed for the door in the door, thereby avoiding people from escaping or taking refuge by using the door in the door under the current disaster environment and avoiding accidents caused by the operation of the door in the door.
In this embodiment, the execution module further includes:
the receiving unit is used for receiving the secondary signal sent by the transmitting end based on the signal instruction being executed;
a judging unit, configured to judge whether the secondary signal collides with the signal instruction being executed;
and the execution unit is used for correcting the instruction to be executed of the door in the current door based on the priority of different signal instructions if the instruction is, wherein the different signal instructions specifically comprise a state inquiry, a timing switch and a request switch.
In this embodiment, the system receives and interprets the secondary signal sent again by the transmitting end based on the signal instruction being executed by the current gate, and then determines whether the secondary signal collides with the signal instruction being executed, so as to execute the corresponding step; for example, when the system determines that the secondary signal does not collide with the signal instruction being executed, the system executes the signal instruction being executed together with the signal instruction corresponding to the secondary signal, for example, one signal instruction indicates "open door", the other signal instruction indicates "start alarm", and simultaneously, the two signals are sent to realize the operations of opening door and starting alarm, the working state of the door in the door is not influenced during the operation, and the alarm effect can be also achieved; for example, when the system determines that the secondary signal collides with the signal command being executed, the system corrects the current command to be executed of the door based on the priority of different signal commands, such as the command a (open door) and the command B (close door) are received simultaneously during the closing of the door.
In this embodiment, the second execution module further includes:
the acquisition unit is used for identifying the color rendering degree of the signal lamp and acquiring the residual electric quantity of the signal lamp based on the color rendering degree;
the second judging unit is used for judging whether the residual electric quantity is larger than a preset available electric quantity value or not;
and the second execution unit is used for flashing the signal lamp through the transmitting end to generate a replacement battery prompt for the signal lamp if not, and correspondingly adjusting the flashing times of the signal lamp based on the consumption duration of the residual electric quantity.
In this embodiment, the system obtains the residual electric quantity of the LED signal lamp according to the color rendering degrees of different degrees by identifying the color rendering degrees of the LED signal lamp, and then judges whether the residual electric quantity is greater than the available electric quantity value in the daily working state of the door in the door so as to execute the corresponding steps; for example, when the system determines that the remaining power can be greater than the available power value, the system keeps monitoring the remaining power of the signal lamp and continues to use the signal lamp to operate with the door in the door until the power of the signal lamp cannot support the signal lamp to continuously emit lights with different colors, i.e. the remaining power is insufficient to continue to operate; for example, when the system determines that the remaining power is not greater than the available power value, the system flashes the LED signal lamp through the transmitting end to generate a power shortage prompt that the signal lamp needs to replace a battery, the signal lamp still maintains color presentation of different instructions during flashing, but the power shortage cannot be continuously presented or the presentation duration is shorter, so that the situation that the signal lamp still maintains high-power-consumption work to enable the power of the signal lamp to be quickly reduced due to the fact that the power of the signal lamp is still low is avoided, the presentation duration of the signal lamp can be reduced linearly, the signal lamp can be kept for enough operation duration to complete the presentation of the remaining color until a worker performs battery replacement when the power of the signal lamp is low, and when the remaining power of the signal lamp is less and less, the number of flashes of the signal lamp is more and more frequent at the moment, namely, the worker is reminded of immediately stopping door operation and performing battery replacement for the signal lamp, and the door in the door cannot normally execute signal instructions through the signal lamp is avoided.

a fourth judging module, configured to judge whether a door in the door has a remaining instruction to be executed;
and the fourth execution module is used for closing the door in the door and disconnecting the power supply for receiving if not, and replacing the battery in the door.
In this embodiment, the system cuts off the gate in the gate to receive any signal instruction before cutting off the power output of the relay, and simultaneously stops the gate in the gate to continue to execute the signal instruction, and then determines whether the gate in the gate has a residual instruction to be executed, so as to execute the corresponding step; for example, when the system determines that the door in the door still has residual instructions to be executed, the system sets a warning mechanism to inform a user or an operator of insufficient battery power in advance when the battery power is nearly exhausted, and sets an instruction cache in a control logic of the door in the door to store the instructions to be executed, so that even if the battery power is exhausted, the instructions to be executed can be temporarily stored in the cache, and the instructions to be executed can still be normally executed after the battery replacement is completed; for example, when the system determines that there are no remaining instructions to be executed on the door-in-door, the system ensures that the door-in-door system is in a closed state before battery replacement, thereby preventing any accidental operation or interference, and requiring a power-off operation before battery replacement is performed, ensuring that no electric shock is suffered when the battery is replaced.

In this embodiment, the system sends a query signal through the transmitting end to obtain the color content currently presented by the signal lamp, and then the system judges whether the color content currently presented accords with the preset working color of the door in the door or not, so as to execute the corresponding steps; for example, when the system determines that the currently presented color content can meet the preset working color of the door in the door, the system considers that the door in the door and the signal lamp can play a linkage role at present, for example, the color of the signal lamp corresponding to the door opening instruction set in the door is green, as long as the color presented by the signal lamp is green, a person needing to see the corresponding signal lamp prompt through the door in the door enters the door in the door, for example, the color of the signal lamp corresponding to the door closing instruction set in the door is red, and as long as the color presented by the signal lamp is red, the person needing to see the corresponding signal lamp prompt through the door in the door needs to wait for the instruction before entering the door in the door; for example, when the system determines that the currently presented color content cannot conform to the preset working color of the door-in-door, the system considers that the door-in-door cannot generate linkage action with the signal lamp at present, the system adds a communication bridge between the door-in-door and the signal lamp, strengthens the communication connection established between the door-in-door and the signal lamp, ensures that the transmission distance and the signal strength of the signal lamp are enough, and the door-in-door can receive the signal, if necessary, can also adjust the position of the signal lamp or increase a signal amplifier, so that the door-in-door and the signal lamp can play the linkage action, and the condition that a person waiting to pass through cannot know the working state of the door-in-door at present through the signal lamp is avoided.
