Background

With the rapid development of artificial intelligence technology, entrance guard devices based on face recognition have been widely used in residential districts and the like. The face access control device generally comprises an access control device, face recognition equipment, a control processing system and the like, wherein the access control device comprises a motor reducing mechanism, a movable door and the like. In practical application, a person who needs to enter or exit a cell respectively enters and recognizes face information by face recognition equipment inside and outside a cell entrance guard, after the face recognition is correct (namely, the face information of the person is recorded in a subsystem of the face recognition equipment), a control processing system (outputting a positive and negative pole power supply) of an entrance guard device can automatically control a motor reducing mechanism to work to open a movable door of the entrance guard (after the movable door moves backwards to a stop point, a limit switch at the rear side of the movable door outputs a signal to a signal input end of the control processing system, the control processing system stops outputting the power supply, the movable door stops moving), after a certain time, the control processing system of the entrance guard device automatically controls the motor reducing mechanism to work to close the movable door of the entrance guard (outputting the positive and negative pole power supply, after the movable door moves forwards to the stop point, the limit switch at the front side of the movable door outputs a signal to the signal input end of the, the control processing system stops outputting the power supply, and the movable door stops moving), so that the next person can get in and out of the cell in preparation.

As shown in fig. 1 and 2, after the 36V power supply output by pins 3 and 4 at two ends of the power supply output of the regulated power supply a1 in the body of the human face access control device enters two ends of the power supply input of the two sets of photoelectric switches a7 and A8, the two sets of photoelectric switches a7 and A8 are in a power-on working state. In practical application, a person who needs to enter or exit a cell advances to enter and identify face information of the person through the face recognition device A2 (7) inside and outside the cell entrance guard, after the face recognition is correct (namely, the face information of the person is entered into the subsystem of the face recognition device A2), the output signal of the face recognition device A2 (7) enters the signal input end of the control processing system A3 of the entrance guard device, therefore, the control processing system A3 (outputting a positive and negative pole power supply) can automatically control the motor speed reduction mechanism M (8) to work to open the movable door 102 of the entrance guard, after a certain time, the control processing system A3 of the entrance guard device automatically controls the motor speed reduction mechanism M to work to close the movable door 102 of the entrance guard (outputting a negative and positive pole power supply), and preparation is made for the next person to enter or exit the cell. When the first path of power output end of the door opening and control processing system A3 outputs a positive and negative pole power supply to enter the positive and negative pole power input end of the motor speed reducing mechanism M, the power supply can enter the two ends of the power input end of the pyroelectric detection mechanism positioned at the rear end of the movable door post 101 through the unidirectional conduction of the diodes VD4 and VD5, and then the pyroelectric detection mechanism is in an electrified working state. When the door is opened, before no one enters the range of a detecting head of the pyroelectric detecting assembly A5, no output is provided for the 3 feet of the pyroelectric detecting assembly A5, then the relay K1 continues to keep the power-off state, the control power supply input end and the normally closed contact end of the relay are communicated, the first path of positive power supply output end of the control processing system A3 is communicated with the positive power supply input end of the motor reducing mechanism M, the motor reducing mechanism M continues to drive the movable door 102 to be opened, until the movable door 102 is fully opened, after the movable door 102 moves backwards to a dead point, a limit switch at the rear side of the movable door outputs a signal to the signal input end of the control processing system A3, the control processing system stops outputting the power supply, and the movable door stops moving. In practical situations, when the movable door 102 is opened, a person in a cell enters the front (2 meters) of the range of a detecting head of the pyroelectric detecting assembly a5, the high level output by the pin 3 of the pyroelectric detecting assembly a5 is subjected to voltage reduction and current limitation by the resistor R2 and enters the base of the NPN triode Q2, the NPN triode Q2 is conducted, the collector of the NPN triode Q2 outputs the low level and enters the negative power input end of the relay K1, and then the relay K1 is in a power-on state, and the control power input end and the normally-closed contact end of the relay are opened, so that the first path of positive power output end of the processing system A3 and the positive power input end of the motor speed reducing mechanism M are opened, the motor speed reducing mechanism M loses power and does not drive the movable door 102 to be opened, and. Meanwhile, the low level output by the collector of the NPN triode Q1 is unidirectionally conducted through a diode VD, and is subjected to voltage reduction and current limitation through a resistor R3 to enter the base of the NPN triode Q3, the NPN triode Q3 is conducted, the collector outputs the low level to enter the negative power input end of the relay K2, and then the relay K2 is electrified to pull in the control power input end and the normally open contact end to be closed. Because the positive power supply input ends of the buzzer B and the prompting lamp H are connected with the normally open contact end of the relay K2, when a person approaches the rear end of the movable door 102 for 2 m in the door opening process, the buzzer B can make a loud prompting sound and the luminous prompting lamp H together prompt the person in the community not to go forward continuously, and collision is prevented. When people in a community hear the prompting sound and see that the prompting lamp H emits light and retreats and the movable door 102 and the pyroelectric detection assembly A5 are separated, the 3 feet of the pyroelectric detection assembly A5 stop outputting, and then the buzzer B and the prompting lamp H lose power and save electric energy (the light emitting surface of the prompting lamp H is positioned outside the element box). When the personnel in the community recover to the position beyond the front 2 meters of the probe of the intermittent pyroelectric detection assembly A5, no output is provided for the 3 feet of the pyroelectric detection assembly A5, then the relay K1 is in a power-off state, the control power supply input end and the normally closed contact end of the relay K1 are communicated between the first positive power supply output end of the control processing system A3 and the positive power supply input end of the motor speed reducing mechanism M, the motor speed reducing mechanism M further continues to drive the movable door 102 to be opened until the movable door 102 is fully opened, the movable door 102 moves backwards to a stop point, the limit switch at the rear side of the movable door outputs a signal to the signal input end of the control processing system, the control processing system stops outputting the power supply, and the movable door stops moving.

As shown in fig. 1 and 2, in practical application, the control processing system A3 of the door control device automatically controls the motor deceleration mechanism M to operate to close the movable door 102 (outputting negative and positive power) of the door control device, so as to prepare for the next person to enter and exit the cell, when the output power of the second power output end of the door control processing system A3 enters the input end of the negative and positive power of the motor deceleration mechanism M, the power will be conducted by the diodes VD2 and VD3 in one way to enter the input ends of the pyroelectric detection mechanism at the front side end of the movable door pillar 101, and then the pyroelectric detection mechanism is in an energized operating state; when the door is closed, before no one enters the range of a probe of the pyroelectric detection assembly A4, no output is generated at pin 3 of the pyroelectric detection assembly A4, the relay K continues to keep a power-off state, the control power input end and the normally closed contact end of the relay K are communicated between the positive electrode of the second path of positive power output end of the control processing system A3 and the positive power input end of the motor speed reducing mechanism M, the motor speed reducing mechanism M continues to drive the movable door 102 to be closed until the movable door 102 is completely closed, after the movable door 102 moves forwards to a stop point, a limit switch on the front side of the movable door outputs a signal to the signal input end of the control processing system, the control processing system stops outputting the power, and the movable door stops moving. In practical situations, when the movable door 102 is closed, a person outside the cell enters the front of the range of a detecting head of the pyroelectric detecting assembly a4 (about 2 meters, the person may collide with the closed movable door when going forward continuously), a high level output by a pin 3 of the pyroelectric detecting assembly a4 is reduced in voltage and limited in current through the resistor R1 and enters the base of the NPN triode Q1, the NPN triode Q1 is conducted, a collector thereof outputs a low level and enters the input end of the negative power supply of the relay K, the relay K is in a powered state, the input end of the control power supply and the normally closed contact end of the relay K are open, so that the output end of the second path of the positive power supply of the control processing system A3 and the input end of the positive power supply of the motor reducing mechanism M are open, the motor reducing mechanism M loses power and does not drive the movable door 102 to. Meanwhile, the low level output by the collector of the NPN triode Q1 is unidirectionally conducted through a diode VD1, and is subjected to voltage reduction and current limitation through a resistor R3 to enter the base of the NPN triode Q3, the NPN triode Q3 is conducted, the collector outputs the low level to enter the negative power input end of the relay K2, and then the relay K2 is electrified to attract the control power input end and the normally open contact end to be closed. Because the positive power supply input ends of the buzzer B and the prompting lamp H are connected with the normally open contact end of the relay K2, when a person approaches the front end of the movable door 102 for 2 m during closing, the buzzer B can make a loud prompting sound and the luminous prompting lamp H together prompt people inside and outside a cell not to continue to move forward, and collision is prevented. When people outside the community hear the prompting sound and see that the prompting lamp H emits light and retreats and the movable door 102 and the pyroelectric detection assembly A4 are separated, the output of the pin 3 of the pyroelectric detection assembly A4 stops, and then the buzzer B and the prompting lamp H lose power and save electric energy. When the personnel outside the community recovers to be beyond 2 meters in front of the probe of the intermittent pyroelectric detection assembly A4, no output is generated at the pin 3 of the pyroelectric detection assembly A4, the relay K loses the power state, the control power supply input end and the normally closed contact end of the relay K are communicated between the second path of positive power supply output end of the control processing system A3 and the positive power supply input end of the motor speed reducing mechanism M, the motor speed reducing mechanism M continues to drive the movable door 102 to be closed, and when the movable door 102 is completely closed and moves forwards to a stop point, the limit switch at the front side of the movable door outputs a signal to the signal input end of the control processing system, the control processing system stops outputting the power supply, and the movable door stops moving.

As shown in fig. 1 and 2, the photoelectric switches a7 and A8 are transversely installed at the lower ends of the front side and the rear side of the movable door, so that no matter people enter or exit a cell, and when a vehicle collides with the movable door, infrared light beams transversely emitted by one set of photoelectric switch a7 or A8 can be blocked, and then 3 feet of one set of the two sets of photoelectric switches a7 or A8 output high levels to enter the positive power input end of the annunciator B, so that the annunciator B in the duty room can emit loud prompt sounds, so that a duty person can timely know the field situation, and the loss of a manager caused by the fact that the manager does not know the movable door. The models of the diodes VD, VD1, VD2, VD3, VD4 and VD5 are 1N 4007; the resistances of the resistors R1, R3 and R3 are 100K, 100K and 47K respectively; the indicator light H is an indicator light with the voltage of 36V (an LED light with a DC-DC voltage reduction and stabilization module can be adopted); the buzzer B, B2 is an active continuous audible alarm with model SFB-55 and working voltage DC 36V; the model numbers of NPN triodes Q1, Q2 and Q3 are 9013; relays K, K1, K2 are DC36V relays.
