Description

Technical Field

[0001] This article relates to access control technology, and more particularly to an access control system control method and device, storage medium, and access control system. Background Technology

[0002] With the development of intelligent access control technology, public places such as office buildings, stadiums, campuses, and communities are beginning to use personnel identification devices combined with speed gates on a large scale to achieve personnel access management and control. The working principle of this solution is that personnel have preset permissions. When a person on the whitelist scans their face, the system compares their permissions and if approved, the gate opens. When an unauthorized person scans their face, the gate does not open and remains closed.

[0003] However, in application scenarios such as communities, there is often a need for electric bicycles to pass through. Electric bicycles travel at relatively high speeds, often requiring riders to stop at the speed gates, be successfully identified, and then pass through. This can cause congestion during rush hour in these communities. Furthermore, some electric bicycles are ridden at high speeds by riders with poor habits, often only braking at the gates. The personnel identification equipment may not be able to recognize them quickly enough, frequently resulting in damage to the gate's gate wings. Summary of the Invention

[0006] When a cyclist moving towards the gate is detected in the target area, an image of the cyclist is acquired. If the cyclist meets the passage conditions based on the image, the gate is opened.

If the image of the moving object is determined to be a cyclist, then a cyclist moving towards the gate is detected in the target area.

[0014] Track the cyclist's trajectory;

[0015] If a person who does not meet the passage conditions or whose passage conditions have not been determined enters the gate before the cyclist, the gate is closed.

[0016] In one exemplary embodiment, the access control system further includes a light curtain system, wherein detecting that a person who does not meet the access conditions or has not undergone access condition determination enters the gate before the cyclist includes:

[0017] The light curtain system detects that individuals who do not meet the passage conditions or whose passage conditions have not been determined, and they enter the gate before the cyclist.

[0039] This embodiment provides a method for detecting the movement and location information (including but not limited to direction of movement, speed of movement, location information, and trajectory of movement) of objects in front. It combines this with a personnel identification device to collect the type of the object (pedestrians and cyclists (including but not limited to those riding electric bikes, bicycles, motorcycles, scooters, etc.)) and the object's speed and direction of movement. When the object's speed reaches a preset value and it is identified as a cyclist, a long-distance image capture is initiated. Based on the captured image, if the passage conditions are met, the gate opens. This embodiment improves passage efficiency and avoids damage to the gate by pre-determining passage conditions and opening the gate when they are met.

[0040] Figure 1 This is a schematic diagram of an access control system provided for an exemplary embodiment. Figure 1 As shown, the access control system provided in this embodiment may include: a controller ( Figure 1 The system comprises a personnel identification device 1 (not shown), a turnstile, a radar module, and a light curtain system. The turnstile may include a turnstile body 2 and turnstile gate wings 7. The radar module may include a first radar sensor 3 and a second radar sensor 4. The light curtain system may include an upper light curtain unit 5 and a lower light curtain unit 6. The controller may be integrated with the turnstile body 2 or with the personnel identification device 1. The turnstile is a channel management device that can block or allow personnel to pass based on information from the personnel identification device 1, the radar module, and the light curtain system. The personnel identification device 1 may include an image acquisition device.

[0041] The controller is configured to control the personnel identification device 1, the turnstile, the radar module, and the light curtain system. For example, it controls the radar module to scan and receive motion and position information returned by the radar module; it controls the personnel identification device 1 to acquire images of objects and receives images returned by the personnel identification device 1; it controls the light curtain system to perform detection and receives detection information returned by the light curtain system; and it controls the state of the door wing 7 to open and close the turnstile. Based on the information reported by the radar module and the personnel identification device 1, when a cyclist moving towards the turnstile is detected in the target area, the controller acquires an image of the cyclist from the personnel identification device 1. Based on the image of the cyclist, if it is determined that the cyclist meets the passage conditions, the controller opens the turnstile (i.e., controls the door wing 7 to be in the open state).

[0042] The radar module is used to detect the motion and position information of objects in front of the radar module and send it to the controller; the motion and position information may include at least one of the following: motion direction, motion speed, position information, motion trajectory, etc.

[0043] The personnel recognition device 1 is used to acquire an image of an object according to the control of the controller, and send the image to the controller;

[0044] The light curtain system is used to scan the interior of the turnstile to detect whether an object has entered the interior. The interior of the turnstile is the passage area of ​​the turnstile.

[0045] In one exemplary embodiment, the gate body 2 may include a first gate body and a second gate body disposed opposite to each other. The first radar sensor 3 may be disposed on the first gate body, and the second radar sensor 4 may be disposed on the second gate body. The first gate body may include a top surface, a bottom surface, and a first to a fourth side surface, wherein the first side surface of the first gate body faces the second gate body, the second side surface is opposite to the first side surface, and the third and fourth side surfaces are adjacent to the first side surface. The first radar sensor 3 may be disposed on at least one of the third and fourth side surfaces of the first gate body, or the first radar sensor 3 may be disposed on the top surface. The second radar sensor 4 is disposed similarly. However, this embodiment is not limited to this; the first radar sensor 3 and the second radar sensor 4 may be disposed independently of the gate body 2, for example, disposed next to the gate body 2.

[0046] In one exemplary implementation, the personnel identification device 1 may be disposed on at least one of the top surfaces of the first gate body and the second gate body, or the personnel identification device 1 may be disposed independently of the gate body 2.

[0047] In one exemplary embodiment, the radar module may include only one radar sensor.

[0048] In one exemplary embodiment, the light curtain system may include only the upper light curtain unit 5 or the lower light curtain unit 6, or it may include more light curtain units.

[0049] Figure 1 The door wing 7 shown is for illustrative purposes only and could be other types of door wings.

[0050] Figure 2 A flowchart illustrating an access control system control method as provided in an exemplary embodiment. Figure 2 As shown, the access control system provided in this embodiment includes a turnstile, and the access control system control method includes:

[0051] Step 201: A rider moving towards the gate is detected in the target area;

[0052] Step 202: Obtain the image of the cyclist, and when the cyclist meets the passage conditions based on the image, control the gate to open.

[0053] The solution provided in this embodiment can detect cyclists in advance during their movement and open the gate in a timely manner when the passage conditions are met, which can improve passage efficiency and avoid damage to the gate.

[0054] In an exemplary embodiment, acquiring the image of the cyclist may involve acquiring the cyclist's facial image. If the cyclist is determined to be a person who can pass based on their facial image, then the passage conditions are met. For example, facial images or facial feature information of a whitelist of individuals (i.e., people who can pass) can be pre-stored, and the cyclist's facial image can be compared with the stored facial images or facial feature information.

[0055] In one exemplary embodiment, detecting a cyclist moving towards the gate in the target area includes:

[0056] If a moving object is detected in the target area, moving towards the gate and moving at a speed greater than a preset threshold, an image of the moving object is acquired. If the image of the moving object is determined to be a cyclist, then a cyclist moving towards the gate is detected in the target area.

[0057] In an exemplary embodiment, the area from the turnstile to a predetermined distance from the turnstile is divided into a first area 10 and a second area 20, where the first area 10 is located on the side of the second area 20 closer to the turnstile; the target area includes the second area 20. That is, in this embodiment, when a cyclist is detected in the second area 20, access permission is determined, and the turnstile is opened when the access conditions are met. The distance from the turnstile can be the distance from the radar module along the passage direction parallel to the inner channel of the turnstile, but is not limited to this; it can be the straight-line distance from the radar module.

[0058] In an exemplary embodiment, detecting a cyclist moving towards the gate in the target area includes: detecting a cyclist moving towards the gate when no moving object is detected in the first area 10, and detecting a cyclist moving towards the gate in the second area 20. The solution provided in this embodiment only performs subsequent access permission determination on cyclists in the second area 20 when no moving object is detected in the first area 10.

[0059] In an exemplary embodiment, when a cyclist moving towards the gate is detected in the second area 20, and the cyclist's image is used to determine that the cyclist meets the passage conditions, the gate is controlled to open; when multiple cyclists moving towards the gate are detected in the second area 20, and the images of the multiple cyclists are used to determine that all of the multiple cyclists meet the passage conditions, the gate is controlled to open; when there is a cyclist who does not meet the passage conditions, the gate is controlled to remain closed.

[0060] Figure 3 This is a schematic diagram illustrating a radar module detecting moving objects. Figure 3 As shown, the radar module detects the direction of movement of a moving object. If movement is detected in the direction of the radar module (i.e., the direction of the gate), the speed of the moving object is detected. When the speed reaches a preset threshold, the controller controls the personnel identification device to start long-distance image capture and determines the type of moving object (pedestrian or cyclist) based on the captured image.

[0061] If the object in front is determined to be a cyclist, long-distance image capture can be initiated (i.e., capture can be performed at a relatively far distance). The captured image is used to determine whether the passage conditions are met. If the passage conditions are met, the gate is opened. If the object in front is determined to be a pedestrian, long-distance image capture is not initiated, but close-range image capture can be initiated (i.e., capture can be performed at a relatively close distance). The captured image is used to determine whether the passage conditions are met. If the passage conditions are met, the gate is opened.

[0062] Figure 4A schematic diagram illustrating the division of a first region 10 and a second region 20 is provided for an exemplary embodiment. (See diagram below.) Figure 4 As shown, there is a first area 10 and a second area 20. The first area 10 is located in the second area 20 on the side closer to the radar (i.e., closer to the gate). The first area 10 is a close-range detection area, used to detect pedestrians, cyclists, etc. at close range. The second area 20 is a long-range detection area, used to detect pedestrians, cyclists, etc. at long range.

[0063] In an exemplary embodiment, the method further includes: detecting a moving object in the first region 10 with its direction of movement toward the gate, acquiring an image of the moving object, and controlling the gate to open when the moving object meets the passage conditions based on the image. The moving object may be a cyclist or a pedestrian. The solution provided in this embodiment can detect objects in advance during their movement and open the gate promptly when the passage conditions are met, thereby improving passage efficiency and avoiding damage to the gate.

[0064] In another exemplary embodiment, when a cyclist moving towards the gate is detected in the first area 10, an image of the cyclist is acquired. If the cyclist's image indicates that the cyclist meets the passage conditions, the gate is opened. When a pedestrian moving towards the gate is detected in the first area 10, the system can wait until the pedestrian stops in front of the personnel identification device before determining whether the pedestrian meets the passage conditions. That is, in this embodiment, only cyclists are pre-determined whether they can pass.

[0065] In an exemplary embodiment, the first area and the second area may not be distinguished. When a cyclist is detected entering the recognition range of the personnel recognition device and moving towards the gate, an image of the cyclist is acquired. If the cyclist meets the passage conditions based on the image, the gate is controlled to open.

[0066] In an exemplary embodiment, when there are moving objects in both the first area 10 and the second area 20, and the movement trajectories are all moving towards the gate, it means that the moving objects want to pass through the gate, and it is then determined whether the moving objects in the first area 10 can pass.

[0067] If there are no moving objects in the first area 10, but there are moving objects in the second area 20, and their speed is greater than or equal to a preset value, then it is determined whether the object is a cyclist. If so, and the trajectory of the cyclist is towards the gate, it means the object wants to pass through the gate, and the passage of the moving object in the second area 20 is then determined. If the moving object in the second area 20 is a pedestrian, no passage determination is made; the determination is made only after the pedestrian reaches the first area 10.

[0068] When there is a moving object in the first area 10 and its trajectory is moving towards the gate, and there is no moving object in the second area 20, it means that the moving object wants to pass through the gate. Then, it is determined whether the moving object in the first area 10 can pass.

[0069] Table 1 below shows the schematic diagram of moving object classification and priority image capture recognition in the first area 10 and the second area 20. The data in the table all represent the moving object's trajectory moving towards the gate.

[0070] Table 1. Classification of Moving Objects and Priority Image Capture Recognition Areas in Region 10 and Region 20 (First Region)

[0071]

[0072]

[0073] As shown in Table 1, when there is a moving object (either a pedestrian or a cyclist) in the first area 10, regardless of whether there is a moving object in the second area 20, only the moving object in the first area 10 is judged to determine whether it is passable. When there is no moving object in the first area 10, but there is a moving object in the second area 20, there are two cases: if the moving object in the second area 20 is a cyclist, then long-distance capture and judgment of whether it is passable are performed; if the moving object in the second area 20 is a pedestrian, then long-distance capture and judgment of whether it is passable are not performed.

[0074] In an exemplary embodiment, the first area 10 can be determined based on a preset cycling speed, the personnel identification response time of the access control system, and the preset margin of the access control system. The second area 20 can be determined based on the identification distance of the access control system and the first area 10. The personnel identification response time of the access control system can be the response time of the personnel identification device 1, and the identification distance of the access control system can be the identification distance of the personnel identification device 1. That is, the first area 10 and the second area 20 can be determined based on the following information: ① preset cycling speed (speed of electric bicycle, bicycle, etc.); ② response time of the personnel identification device 1; ③ identification distance of the personnel identification device 1; ④ margin reserved by the access control system.

[0075] For example, in application scenarios such as communities, the preset cycling speed is V = 20km / h (5.55m / s); the response time of personnel identification device 1 is t = 500ms; the identification distance of personnel identification device 1 is l = 0~10m; and the system's margin is k = 60%.

[0076] Calculate V*t / k = 5.55 m / s * 500 ms ÷ 60% = 4.625 m; then the first region 10 can be determined based on this value. For example, the first region 10 is a close-range detection region, divided into areas 0 to 5 meters away from the radar, i.e., L1 = 5 m; the second region 20 is a long-range detection region, divided into areas 5 to 10 meters away from the radar, i.e., L2 = 5 m.

[0077] The following example illustrates the technical solution disclosed herein.

[0078] Figure 5 A flowchart of an access control system control method provided as an exemplary embodiment. Figure 5 As shown, the access control system control method provided in this embodiment includes:

[0079] Step 501: Power on and initialize the gate device;

[0080] Step 502: The radar module detection area is divided into different blocks, namely, the first area 10 and the second area 20.

[0081] In another exemplary embodiment, the radar module may not detect the area, but directly determine the first area 10 and the second area 20 based on the relevant parameters of the first area 10 and the second area 20 configured in the system;

[0082] Step 503: The radar module detects moving objects in front;

[0083] Step 504: Determine if there is a moving object moving towards the gate. If yes, proceed to step 505; otherwise, return to step 503.

[0084] Step 505: Remove moving objects whose direction of movement is away from the gate;

[0085] Step 506: Count the areas to which the remaining moving objects belong, that is, count the areas to which the moving objects whose direction of movement is toward the gate belong;

[0086] Step 507: Determine whether there is a moving object in the first area 10 that is moving towards the gate. If there is, proceed to step 508; otherwise, proceed to step 509.

[0087] Step 508: Capture and identify moving objects in the first area 10, and determine whether the moving object meets the passage conditions. If it does, the gate opens; if it does not, the gate remains closed, and the process ends.

[0088] In the first area 10, the moving object can be a pedestrian or a cyclist.

[0089] Step 509: Determine whether there is a moving object in the second area 20 that is moving towards the gate. If there is, proceed to step 510; otherwise, proceed to step 512.

[0090] Step 510: The personnel recognition device acquires an image of a moving object and determines whether the moving object is a cyclist based on the image. If yes, proceed to step 511; otherwise, proceed to step 512.

[0091] Step 511: Capture and identify moving objects in the second area 20, and determine whether the moving object meets the passage conditions. If it does, the gate opens; if it does not, the gate remains closed, and the process ends.

[0092] In step 510, acquiring the image of the moving object can be acquiring the overall image of the moving object and determining whether it is a cyclist, for example, determining whether it matches an electric vehicle or a bicycle. In step 511, capturing and recognizing the moving object in the second region 20 can be capturing the facial image of the moving object in the second region 20 for facial recognition.

[0093] Step 512: No image capture or recognition is performed, and the process ends. That is, pedestrian access is not determined in the second area 20. Access is determined only after pedestrians enter the first area 10 and are detected.

[0094] When a moving object is detected as a cyclist moving towards the gate and the passage conditions are met, the gate opens; if someone suddenly cuts in, it is intended to allow quick passage without authentication (e.g., unauthorized personnel, etc.). Figure 6 As shown, the electric scooter rider is an authorized user, allowed to pass at a distance, but the pedestrian is an unauthorized user (intended to pass quickly without authentication), potentially leading to unauthenticated individuals passing through the gate. In one exemplary implementation, after determining that the rider meets the passage conditions based on the rider's image and controlling the gate to open, the system further includes:

[0095] Track the cyclist's trajectory;

[0096] If a person who does not meet the access requirements or whose access requirements have not been determined enters the gate before the cyclist, the gate will be closed. The solution provided in this embodiment can prevent unidentified persons or those who do not meet the access requirements from intruding, thus improving security.

[0097] In one exemplary embodiment, the access control system further includes a light curtain system, wherein detecting that a person who does not meet the access conditions or has not undergone access condition determination enters the gate before the cyclist includes:

[0098] The light curtain system detects that individuals who do not meet the passage conditions or whose passage conditions have not been determined, and they enter the gate before the cyclist.

[0099] The following is a specific example to illustrate this. Figure 7 A flowchart of an access control system control method provided as an exemplary embodiment. Figure 7 As shown, the access control system control method provided in this embodiment includes:

[0100] Step 701: The cyclist was successfully identified remotely and the gate was successfully opened remotely. That is, the cyclist was identified and passed through the second area 20, and the gate opened.

[0101] However, this embodiment is not limited to this; it could also be that the cyclist in the first area 10 is successfully identified.

[0102] Step 702: The radar module and the personnel identification device lock the location information of the cyclist, and the radar module performs trajectory tracking.

[0103] The radar module and the personnel identification device establish a coordinate connection to confirm their respective zero-point positions. Once the cyclist is successfully identified, the personnel identification device confirms the cyclist's position, and the radar module simultaneously records the cyclist's position information. Subsequently, the radar module is responsible for tracking the cyclist's trajectory information.

[0104] Step 703: The radar module and the light curtain system work together.

[0105] The radar module scans for moving objects.

[0106] Step 704: Determine if any unidentified person has arrived at the gate before the cyclist. If not, continue waiting; if so, proceed to step 705.

[0107] Based on the scanning results of the radar module and the trajectory information of the cyclists tracked by the radar module, it is determined whether any unidentified persons have arrived at the front of the gate before the cyclists.

[0108] Step 705: The unidentified person has reached the front of the gate (there are several possibilities in the future: moving away from the gate, remaining still, or moving closer to the gate). Determine whether the unidentified person's direction of movement is towards the gate. If not, continue to wait; if so, proceed to step 706.

[0109] Step 706: The radar module informs the light curtain system that unidentified personnel may be about to intrude.

[0110] Step 707: Determine whether the unidentified person has reached the inside of the turnstile (i.e., entered the turnstile). If not, continue to wait; if so, close the turnstile door wings to ensure that the unidentified person does not intrude, i.e., prevent the unidentified person from intruding.

[0111] Among them, determining that an unidentified person has entered the gate can be done by using a radar module to sense the unidentified person moving into the gate and by using a light curtain system to detect that the light curtain is being blocked.

[0112] The solution provided in this embodiment can identify unidentified intruders, ensuring that all personnel passing through are those who meet the access requirements, thereby improving security.

[0113] In one exemplary embodiment, access can be identified for unidentified persons. If the access conditions are met, the gate remains open; if the access conditions are not met, the gate is closed.

[0114] In one exemplary embodiment, the gate can be closed when an unidentified person has arrived in front of the gate before the cyclist, and the cyclist can be identified or the gate can be opened directly after the cyclist arrives in front of the gate.

[0115] In the solution provided by at least one of the above embodiments, radar technology is used to determine the type of moving object in front, enabling long-distance door opening, which can greatly improve traffic efficiency, alleviate congestion during rush hours, and reduce the frequent damage to gate wings.

[0116] like Figure 8 As shown, this embodiment of the present disclosure provides an access control system control device 80, including a memory 810 and a processor 820. The memory 810 stores a program, which, when read and executed by the processor 820, implements the access control system control method described in any of the above embodiments.
