The invention is described in further detail below with reference to specific embodiments.
The channel gate visitor management system is shown in fig. 1 and comprises a channel gate 1, wherein the channel gate 1 comprises a first body 11, a second body 12, a gate 3, a face recognition device 4, a first passing sensor 5, a second passing sensor 6 and a controller (not shown in the figure), the first body 11 and the second body 12 are arranged oppositely, and a pedestrian channel 2 is arranged between the first body 11 and the second body 12.
The two gates 3 are arranged in the pedestrian passageway 2, the pedestrian passageway 2 is normally closed, the two gates 3 are respectively provided with one driving mechanism 7, and the driving mechanisms 7 of the two gates 3 are respectively arranged on the first body 11 and the second body 12. It should be noted that the driving mechanism 7 drives the gate 3 to rotate by using a servo motor, which is a conventional technology and is not described herein again.
The first passing sensor 5 is arranged at the entrance of the pedestrian passage 2 and used for detecting passing objects entering the pedestrian passage 2 and the number of the passing objects; the second passing sensor 6 is arranged at the installation position of the gate 3, and the second passing sensor 6 is located at a position higher than the top of the gate 3 and is used for detecting passing objects passing through the gate 3 and the number of the passing objects, namely detecting passing objects passing through the pedestrian passage 2 and the number of the passing objects. In this embodiment, the first traffic sensor 5 and the second traffic sensor 6 both employ infrared photoelectric sensors, which include an infrared light emitter and an infrared light receiver aligned with each other, wherein the infrared light emitter is installed on the first body 11, and the infrared light receiver is installed on the second body 12 (fig. 1 shows only the infrared light receiver installed on the second body 12 of the first traffic sensor 5 and the infrared light receiver installed on the second body 12 of the second traffic sensor 6 due to the problem of viewing angle), that is, the infrared light emitter and the infrared light receiver are respectively installed on two sides of the pedestrian passageway 2, and the infrared light emitter emits infrared light to the infrared light receiver in a normal state. When an object enters the entrance of the pedestrian passage 2 and blocks a light path between the infrared light emitter and the infrared light receiver of the first passing sensor 5, the infrared light receiver of the first passing sensor 5 outputs a control signal to realize that the object enters the entrance of the pedestrian passage 2; when an object passes through the gate 3, namely the object passes through the pedestrian passageway 2 and blocks a light path between the infrared light emitter and the infrared light receiver of the second traffic sensor 6, the infrared light receiver of the second traffic sensor 6 outputs a control signal, so that the object passing through the pedestrian passageway 2 is detected.
In this embodiment, the Controller is electrically connected to the face recognition device 4, the first traffic sensor 5, the second traffic sensor 6, and the driving mechanism 7 of the two gates 3, and the Controller is a Programmable Logic Controller (PLC), which is a digital Logic Controller for automation control. The controller comprises a computer-readable storage medium and a processor, which are connected to each other, wherein a computer program is stored on the computer-readable storage medium, and when the computer program is executed by the processor, the method for managing visitor to the channel gate as shown in fig. 2 is implemented, and the specific flow is as follows A, B, C, D, E, F, G, H, I.
A. Shooting a real-time picture at an entrance of a pedestrian passageway 2 by using a face recognition device 4 and recognizing a first face image of a visitor from the real-time picture;
in this embodiment, the face recognition device 4 includes a camera 41 and a display screen 42, the shooting direction of the camera 41 faces the entrance of the pedestrian passageway 2, and the recognition direction of the face recognition device 4 faces the entrance of the pedestrian passageway 2. When the face recognition device 4 works, the camera 41 is used for shooting a real-time picture at the entrance of the pedestrian passageway 2, the face image of a visitor is recognized from the real-time picture, the real-time picture is displayed on the display screen, and the visitor can move the face of the visitor after checking the real-time picture so as to display the face image in the center of the real-time picture, so that the face recognition is facilitated. When the channel gate visitor management system works, the controller shoots a real-time picture at the entrance of the pedestrian channel 2 by using the face recognition device 4, and when a visitor prepares to pass through the pedestrian channel 2, the visitor can come to the entrance of the pedestrian channel 2, and then the first face image of the visitor can be recognized by the controller from the real-time picture shot by the face recognition device 4.
B. And C, judging whether the visitor has the passing authority according to the first face image, if not, executing the step C, and if so, executing the step D, E, F.
In this embodiment, a plurality of white list face images allowing passage are stored in advance in a computer readable storage medium of the controller. After the first face image of the visitor is identified, the controller compares the first face image with a plurality of pre-stored white list face images one by one in similarity, and judges whether a white list face image with similarity reaching a preset similarity value (for example, 90%) exists in the plurality of white list face images: if the white list face image with the similarity reaching the preset similarity value does not exist, the controller judges that the visitor does not have the passing permission, and under the condition, the controller executes the following step C; if the white list face image with the similarity reaching the preset similarity value exists, the controller judges that the visitor has the passing authority, and under the condition, the controller executes the following step D, E, F.
C. The gate 3 is kept in a state of closing the pedestrian passageway 2.
In the case where it is determined that the visitor does not have the passage authority, the controller causes the two gates 3 to maintain the state of closing the pedestrian passageway 2, preventing the visitor from passing through the pedestrian passageway 2.
D. The gate 3 is made to open the pedestrian passageway 2 for visitors to pass through.
Under the condition that the visitor is judged to have the passing authority, the controller enables the two driving mechanisms 7 to drive the two gates 3 to rotate to open the pedestrian passage 2 for the visitor to pass.
E. The first traffic sensor 5 detects traffic entering the pedestrian passageway 2 and the number thereof, and the second traffic sensor 6 detects traffic passing through the pedestrian passageway 2 and the number thereof.
During the gate 3 opens the pedestrian passageway 2 for visitors to pass, the controller detects the passing objects entering the pedestrian passageway 2 and the number thereof using the first pass sensor 5, and detects the passing objects passing through the pedestrian passageway 2 and the number thereof using the second pass sensor 6. At this time, the visitor entering the pedestrian passageway 2 through the entrance of the pedestrian passageway 2 enables the first passing sensor 5 to detect the passing object, and the visitor enables the second passing sensor 6 to detect the passing object through the gate 3.
F. And judging whether a second face image of other people can be recognized from the real-time picture, if so, executing the following step G, and if not, executing the following step H.
During the period that the gate 3 opens the pedestrian passageway 2 for visitors to pass, the controller judges whether a second face image of other people can be identified in the real-time picture shot by the face recognition device 4, if yes, the controller means that a person is behind the visitors, so the controller executes the following step G, and if not, the controller means that no person is behind the visitors, so the controller executes the following step H.
G. And judging whether the distance between other people and the face recognition device 4 is smaller than a preset threshold value according to the size of the second face image, if not, executing the following step H, and if so, executing the following step I.
It should be noted that, the closer a person is to the face recognition device 4, the larger the size of the face image recognized by the face recognition device 4 is, so that, in the case that the face recognition device 4 recognizes a second face image of another person, the controller analyzes the distance between the other person and the face recognition device 4 according to the size of the second face image in the real-time frame, and can determine whether the distance is smaller than a preset threshold (for example, 1 meter). If the distance is not less than the preset threshold, it means that the other person is not too close to the face recognition device 4, and the other person does not enter the entrance of the pedestrian passageway 2, it can be concluded that the other person is not a following person who wants to follow the visitor through the pedestrian passageway, but a person who is queued behind the visitor, so the controller executes the following step H; if the distance is less than the preset threshold, it means that the other person is too close to the face recognition device 4 and the other person has entered the entrance of the pedestrian passageway 2, it can be concluded that the other person is a trailing person who wants to follow the visitor through the pedestrian passageway 2, so the controller performs the following step I.
H. And (4) judging whether the second traffic sensor 6 detects traffic, if so, executing the following step H1, and if not, executing the following step H3.
H1, determining whether the number of passing objects detected by the second passing sensor 6 is equal to the number of passing objects detected by the first passing sensor 5, if yes, executing the following step H2, and if not, executing the following step H3;
h2. Returning the gate 3 to the condition closing the pedestrian passage 2;
h3. keeps gate 3 in the state of opening pedestrian passageway 2, and then step H is repeatedly performed.
Under the condition that no person exists behind the visitor or other persons exist behind the visitor but the visitor is not a following person (namely, the distance between the other person and the face recognition device 4 is judged to be not less than a preset threshold value according to the size of the second face image of the other person), if the visitor does not carry luggage, only the visitor enters the entrance of the pedestrian passage 2, so that the first passing inductor 5 detects a passing object (visitor), and the controller judges whether the second passing inductor 6 detects the passing object or not, specifically: if the second passing sensor 6 does not detect the passing objects, the visitor does not pass through the pedestrian passageway 2, at the moment, the controller judges that the number (0) of the passing objects detected by the second passing sensor 6 is not equal to the number (1) of the passing objects detected by the first passing sensor 5, so that the controller enables the gate 3 to keep the state of opening the pedestrian passageway 2 for the visitor to pass through, then the step H is repeatedly executed, and whether the number of the passing objects detected by the second passing sensor 6 is equal to the number of the passing objects detected by the first passing sensor 5 is continuously judged; if the second passing sensor 6 detects a passing object, it means that the visitor has passed through the pedestrian passageway 2, and at this time, the second passing sensor 6 detects a passing object, the controller determines that the number (1) of the passing objects detected by the second passing sensor 6 is equal to the number (1) of the passing objects detected by the first passing sensor 5, so that the controller makes the gate 3 return to the state of closing the pedestrian passageway 2 to wait for the next visitor.
Nobody in visitor rear, or visitor rear someone but this person is not under the condition of trailing personnel, if the visitor carried luggage article, then the visitor can be drawn luggage article and get into pedestrian passageway 2's entrance, so first passing inductor 5 can detect two passerby (visitor and luggage article), and the controller judges this moment whether passing inductor 6 detects the passerby, specifically: if the second passing sensor 6 does not detect the passing objects, the visitor does not pass through the pedestrian passageway 2, at the moment, the controller judges that the number (0) of the passing objects detected by the second passing sensor 6 is not equal to the number (2) of the passing objects detected by the first passing sensor 5, so that the controller enables the gate 3 to keep the state of opening the pedestrian passageway 2 for the visitor to pass through, then the step H is repeatedly executed, and whether the number of the passing objects detected by the second passing sensor 6 is equal to the number of the passing objects detected by the first passing sensor 5 is continuously judged; if the second passing sensor 6 detects a passing object, it means that the visitor has passed through the pedestrian passageway 2, but the baggage item carried by the visitor has not passed through the pedestrian passageway 2 at this time, the controller determines that the number (1) of passing objects detected by the second passing sensor 6 is not equal to the number (2) of passing objects detected by the first passing sensor 5, so that the controller causes the gate 3 to keep the state of opening the pedestrian passageway 2, then repeatedly executes step H, and continuously determines whether the number (2) of passing objects detected by the second passing sensor 6 is equal to the number (2) of passing objects detected by the first passing sensor 5 until the second passing sensor 6 detects a second passing object, it means that the baggage item carried by the visitor has passed through the pedestrian passageway 2, at this time, the controller determines that the number (2) of passing objects detected by the second passing sensor 6 is equal to the number (2) of passing objects detected by the first passing sensor 5, so that the controller causes the gate 3 to return to the state of closing the pedestrian passageway 2, and wait for the next visitor.
