Technical Field

The application relates to the technical field of entrance guard, in particular to a bidirectional entrance guard control system and a control method thereof.

Background

At present, with the improvement of safety awareness of people, access control systems for managing personnel to enter and exit are increasingly applied to various fields such as daily life, travel and work, for example, the access control systems can be applied to the entrance and exit management of scenes such as communities, companies, subway stations and parks.

The access control system adopted at the present stage can be a one-way access control system only allowing one-way passage, and can also be a two-way access control system allowing two-way passage. For a bidirectional access control system, authentication devices are installed in two directions, and the authentication devices in the two directions can control the access control equipment to be opened, namely, the user of the authentication device in each direction controls the access control equipment to open the door for the passing user in the direction. However, when the user passes through the two directions at the same time, the authentication devices in the two directions can control the access control device to be opened, that is, the access control device can receive two opening instructions at the same time. In this case, the access control device may only execute one of the opening commands, and the situation may occur that the user identity authentication in a certain direction passes, but the access control device is reversely opened, or the user cannot pass through in one direction.

Therefore, by using the control system of the bidirectional access control in the prior art, the situation that the access control equipment is reversely opened or a user cannot pass through one direction may occur.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The following describes a bidirectional access control system and a control method thereof according to an embodiment of the present application in detail with reference to the drawings.

Fig. 1 is a schematic structural diagram of a bidirectional access control system according to an embodiment of the present application, and as shown in fig. 1, the system includes a first authentication device 110 and a second authentication device 120; the first identity authentication device 110 is connected to the second identity authentication device 120, the second identity authentication device 120 is connected to the two-way access control device, and the access control device is controlled to be opened by the second identity authentication device 120. In specific implementation, the first authentication device 110 and the second authentication device 120 may be connected through a serial port, a network, or the like, and the access control device may be a gate.

Specifically, the first authentication device 110 is configured to perform identity authentication on a user passing through the bidirectional channel in a first direction, and send a first door opening request to the second authentication device 120 after the user passes the authentication; the first door opening request is used for requesting to open a door for a user passing in a first direction, and the first door opening request carries identification information of the first direction;

the second identity authentication device 120 is configured to receive the first door opening request, add the first door opening request to a door opening request queue, perform identity authentication on a user passing through the bidirectional door access in a second direction, add the second door opening request to the door opening request queue after the authentication is passed, and control the door access device of the bidirectional door access to open a door for the user passing through in the first direction or the second direction according to an arrangement sequence of the door opening requests in the door opening request queue; and the second door opening request is used for requesting to open a door for a user passing in the second direction, and the second door opening request carries identification information of the second direction.

The identification information of the first direction and the second direction may be direction names or numbers. In addition, in this application embodiment, any one direction of the bidirectional access control can be regarded as the first direction, and correspondingly, the other direction is regarded as the second direction.

In this embodiment of the application, the first authentication device 110 does not have the authority to control the access control device to open, and the two passing directions all control the access control device to open through the second authentication device 120, so that the situation that the access control device is reversely opened when the users pass through in the two passing directions is avoided, or the users cannot pass through in one direction is avoided. .

Specifically, the first authentication device 110 and the second authentication device 120 may be at least one of a face recognition device, a fingerprint recognition device, a card swiping device, and the like. In an embodiment, if the first authentication device 110 and the second authentication device 120 are both face recognition devices, in this embodiment, the first authentication device 110 is specifically configured to:

acquiring a face image of a user passing from a first direction, and performing identity authentication on the user based on the face image;

the second identity authentication device 120 is specifically configured to:

and acquiring a face image of the user passing from the second direction, and authenticating the user based on the face image.

In a specific embodiment, based on a specific application scenario of the bidirectional access control, the background management platform may issue the information of the person with the right of passage to the first authentication device 110 and the second authentication device 120 in advance. The person information includes at least identity information of the user, facial features of the user, and the like.

In specific implementation, regardless of the first identity authentication device 110 or the second identity authentication device 120, after the face image is collected, the face features in the face image are extracted, the similarity value between the face features and each stored face feature is respectively calculated, whether a face feature with a similarity value larger than or equal to a set threshold exists is detected, and if the face feature exists, the identity authentication of the user is passed.

It should be noted that, in the embodiment of the present application, in the second authentication device 120, both the first door opening request and the second door opening request are arranged in the same door opening request queue.

Specifically, each door opening request in the door opening request queue may be arranged according to the time sequence in which the second identity authentication device 120 acquires the door opening request, and the earlier the acquired time is, the earlier the door opening request is arranged in the request queue. Accordingly, in this case, the second authentication device 120 is specifically configured to:

and determining the arrangement positions of the first door opening request and the second door opening request in the door opening request queue according to the acquisition time of the first door opening request and the second door opening request, and adding the first door opening request and the second door opening request to the arrangement positions.

In a specific implementation, the second identity authentication device 120 may add the acquired door opening request to the tail position of the door opening request queue every time the second identity authentication device acquires a door opening request, or add the door opening request acquired in the period of time to the door opening request queue every set time interval.

For ease of understanding, the following description will be given by way of example.

Assuming that three door opening requests exist in the current door opening request queue, namely a first door opening request 1, a second door opening request 1 and a first door opening request 2 in sequence from front to back, the second authentication device 120 receives the first door opening request 3 sent by the first authentication device 110 at 31 minutes and 20 seconds at 9 am, the second door opening request 2 is generated at the above-mentioned 9 hours 31 minutes 21 seconds, and it can be determined from the acquisition timings of the first door opening request 3 and the second door opening request 2 that the first door opening request 3 should be arranged behind the first door opening request 2, the second door opening request 2 should be arranged behind the first door opening request 3, and adding the first door opening request 3 and the second door opening request 2 to the door opening request queue according to the determined positions respectively, wherein the formed arrangement schematic diagram of the door opening request queue is shown as the diagram in fig. 2 (a).

Of course, besides arranging the door opening requests in the door opening request queue according to the time sequence, the arrangement rules of the first door opening request and the second door opening request in the door opening request queue can be determined according to the pedestrian volume in the first direction and the second direction, and the first door opening request and the second door opening request are added to the door opening request queue according to the determined arrangement rules. Accordingly, in this case, the second authentication device 120 is specifically configured to:

and determining the arrangement rules of the first door opening request and the second door opening request in each time period according to the traffic data passing from the first direction and the second direction in each time period, and adding the first door opening request and the second door opening request acquired in the time period to a door opening request queue according to the arrangement rules corresponding to each time period.

The time periods can be divided according to the pedestrian volume data passing in the first direction and the second direction in the application scene corresponding to the bidirectional access control system. For example, if the bidirectional access control system is applied to company access management, the traffic flow entering the company is significantly greater than the traffic flow exiting the company during the work hours, and the traffic flow exiting the company is significantly greater than the traffic flow entering the company during the work hours. Thus, the morning of 7:30 PM to 9:30 PM, the afternoon of 12:00 PM to 1:30 PM, the afternoon of 1:30 PM to 5:30 PM, the afternoon of 5:30 PM to 6:30 PM, and the evening of 6:30 PM to the next morning of 7:30 PM may be used as a time slot. Of course, the time periods divided herein are only exemplary and do not constitute a limitation on the embodiments of the present application.

In specific implementation, when the arrangement rule is determined according to the pedestrian flow data passing from the first direction and the second direction in each time period, the direction with a large pedestrian flow and the direction with a small pedestrian flow in the time period can be arranged according to a set proportion.

For example, continuing with the example above, during the time period 7:30-9:30 early, the traffic in the first direction (entering the company) is significantly greater than the traffic in the second direction (exiting the company), in which case, to relieve traffic pressure in the first direction, the entry of the work crew into the company is not delayed, and in the door opening request queue, a second door opening request may be inserted for each consecutive queue of at least 5 first door opening requests. One possible arrangement is shown in fig. 2 (b). In the queue diagram shown in fig. 2(b), 5 first door-opening requests are queued between two second door-opening requests.

In the time period of 9:30-12:00 in the morning, the traffic data in the first direction and the traffic data in the second direction have no obvious difference, so that the first door opening request and the second door opening request can be added into the door opening request queue according to the sequence of the acquisition time.

In the embodiment of the application, the arrangement rules set in different time periods are different, and when the application is implemented, the arrangement rules corresponding to the time periods can be preset based on the traffic rules in the application scene, so that the arrangement rules corresponding to the time periods are directly called to perform the arrangement of the first door opening request and the second door opening request in the corresponding time periods.

In the above example, the second authentication device 120 may add the first door opening request and the second door opening request to the door opening request queue at least in the following two ways in the time period 7:30-9:30 earlier.

In the first mode, after the second identity authentication device 120 generates the second door opening request, it is determined whether at least five first door opening requests have been inserted into the door opening request queue at the current time since the second door opening request was generated last time, and if yes, the second door opening request generated at the current time is added to the tail position of the door opening request queue; and if not, continuously adding the received first door opening requests into the door opening request queue until counting is started from the generated second door opening request, and adding the second door opening request into the door opening request queue after five first door opening requests continuously exist in the door opening request queue.

In a second mode, after the second identity authentication device 120 generates the second door opening request, the second door opening request is added to the end position of the current door opening request queue, after the second identity authentication device 120 receives the first door opening request sent by the first identity authentication device 110, it is determined whether there are 5 consecutive first door opening requests in front of the second door opening request, if yes, the currently received first door opening request is added to the end position of the current door opening request queue, otherwise, the currently received first door opening request is added in front of the second door opening request at the end position.

In the embodiment of the application, the arrangement rules of the first door opening requests and the second door opening requests in different time periods are set, and the obtained first door opening requests and the second door opening requests are arranged according to the arrangement rules corresponding to the time periods, so that a user in a traffic peak direction can be allowed to pass continuously as much as possible, the traffic pressure in the traffic direction in the traffic peak period can be relieved, the traffic efficiency in the traffic direction can be ensured, and the waiting time of the user in the traffic peak direction can be shortened.

Since the two-way access control channel can be used for users in two directions to pass through, and only one-direction users can pass through at the same time in order to prevent collision, in the embodiment of the application, when the access control device is controlled to open the door for a user passing in the first direction, the passing user in the second direction cannot pass through, and at this time, the second identity authentication device 120 can be controlled to enter the stop identity authentication mode; when the door access is controlled to open the door for the user passing in the second direction, the user passing in the first direction cannot pass, and the first identity authentication device 110 can be controlled to enter the identity authentication stopping mode. Therefore, the second identity authentication device 120 is further specifically configured to:

after controlling the access control device to open the door for the passing user in the second direction, sending an authentication stop instruction to the first authentication device 110, so that the first authentication device 110 executes an operation of entering an authentication stop mode after receiving the instruction; wherein the instruction carries a first time length for the first authentication device 110 to enter the authentication stop mode;

Specifically, when the user passes through the second direction, the second authentication device 120 authenticates the identity of the user passing through the second direction, after the authentication passes, a second door opening request is generated, and the door opening request is added to the door opening request queue, the second authentication device 120 controls the door access device to open according to the sequence of the door opening requests in the door opening request queue, when the second door opening request is reached, the second authentication device 120 controls the door access device to open the door to the user passing through the second direction, since the user is not allowed to pass through the first direction in order to prevent collision during the passing through process of the user from the second direction, an instruction for stopping authentication can be sent to the first authentication device 110, after the instruction is received by the first authentication device 110, the operation of entering the stop authentication mode is executed, and when the time length of entering the stop authentication mode reaches the first time length, and entering the identity authentication mode again.

The specific values of the first time length and the second time length may be equal or unequal.

In some specific application scenarios, for example, when one direction of the bidirectional access control is in a traffic rush hour in a certain time period, in order to relieve the traffic pressure in the traffic direction, the time length for the other direction to enter the stop authentication mode may be prolonged, so that a user passing in the traffic rush hour direction may pass continuously, thereby relieving the traffic pressure in the direction. Because the pedestrian volume data passing from the first direction and the second direction in different time periods are different, the values of the first time length and the second time length are different aiming at different time periods.

For example, continuing to use the above example, in the time period from 7:30 to 9:30, the number of users passing in the first direction is large, the number of users passing in the second direction is small, and in order to relieve the passing pressure in the first direction, it is necessary to allow users passing in the first direction to pass continuously as much as possible, so the value of the second time length may be set to be larger than that of the first time length.

Specifically, the values of the first time length and the second time length in each time period may all be determined by the second identity authentication device 120. Therefore, the second identity authentication device 120 is further specifically configured to:

determining pedestrian volume data passing from a first direction and a second direction in each time period, and determining values of a first time length and a second time length in each time period according to the pedestrian volume data; wherein the time period is divided based on traffic data of people passing from the first direction and the second direction.

Specifically, in dividing the time period, a point in time at which traffic data of the person who has traveled from the first direction and from the second direction significantly changes may be taken as a division point of the time period. For example, continuing with the above example, for a two-way access control system applied to a doorway of a company, the traffic entering the company is significantly greater than the traffic exiting the company during the peak working hours of the day 7:30-9:30, and after 9:30, there is no large difference between the traffic entering the company and the traffic exiting the company, so that 9:30 can be used as a division point of the above time period.

In specific implementation, the values of the first time length and the second time length can be determined according to the ratio of the pedestrian volume data passing from the first direction to the pedestrian volume data passing from the second direction in each time period. For example, if the ratio of the pedestrian volume passing through from the first direction to the pedestrian volume passing through from the second direction is 10:1 in a certain time period, the values of the first time length and the second time length may be determined according to the ratio of the first time length to the second time length being 1: 10.

Of course, in another specific embodiment, if the flow of people passing through the bidirectional access control system from the first direction is significantly greater than the flow of people passing through the bidirectional access control system from the second direction, the first direction is determined as the main passing direction of the bidirectional access control system, and accordingly, the first time length takes a smaller value, and the second time length takes a larger value, so that the time for the second authentication device to enter the authentication stop mode is longer, and the user in the first direction can pass through the bidirectional access control system continuously in the period of time, thereby relieving the passing pressure in the first direction; similarly, if the traffic of the people passing from the second direction is obviously greater than the traffic of the people passing from the first direction in a certain time period, the second direction is determined as the main traffic direction of the bidirectional access control system, the first direction is the auxiliary traffic direction, in this case, the first time length takes a larger value, and the second time length takes a smaller value, so that the time for the first authentication device to enter the authentication stop mode is longer, and the users in the second direction can pass continuously in the time period, thereby relieving the traffic pressure in the second direction.

In the embodiment of the application, specific values of the first time length and the second time length are determined according to the traffic data passing from the first direction and the second direction, the value of the time length for the traffic direction with less traffic to enter the stop authentication mode is set to be larger, and the identity authentication equipment arranged in the traffic direction with more traffic can be allowed to continuously authenticate the passing user within the time length, so that the user in the traffic direction with more traffic can continuously pass within a longer period of time, and the traffic pressure of the traffic direction with more traffic is relieved.

In this embodiment of the present application, specific values of the first time length and the second time length in each time period may be determined uniformly by the second identity authentication device 120, so that the second identity authentication device 120 carries the first time length in the instruction sent to the first identity authentication device 110; of course, the first authentication device 110 may determine the value of the first time length in each time period, and the second authentication device 120 may determine the specific value of the second time length in each time period, so that it is avoided that the first time length is still carried in the instruction when the second authentication device 120 sends the instruction to stop the authentication to the first face device, and thus the size of the data sent by the second authentication device 120 to the first authentication device 110 may be reduced, thereby reducing the data transmission delay and increasing the data transmission speed.

In this case, the second identity authentication device 120 is specifically configured to:

after controlling the access control equipment to open a door for a user passing in the second direction, sending an instruction for stopping authentication to the first identity authentication equipment; wherein the instruction is for instructing the first authentication device to perform an operation of entering a stop authentication mode, and a first length of time to enter the stop authentication mode is stored in the first authentication device 110;

For example, in one embodiment, the prestored values are 2, 4, 6, 8, 10, and 12, and the set rule may be that when the ratio of the pedestrian volume data in the first direction and the second direction is greater than 50, the smallest value of the values is selected as the value of the first time length, the largest value of the values is selected as the value of the second time length, when the ratio of the pedestrian volume data in the first direction and the second direction is less than or equal to 50 and greater than 20, the second smallest value of the values is selected as the value of the first time length, the second largest value of the values is selected as the value of the second time length, and so on. Of course, this is merely an example and does not limit the embodiments of the present application.

In addition, in the embodiment of the present application, regardless of whether the first authentication device 110 or the second authentication device 120 enters the stop authentication mode, in order to facilitate the waiting time for the user to know that the user still needs to wait, a countdown operation is performed. Specifically, the remaining duration of the current stop authentication mode may be broadcasted in a voice broadcast manner, or the remaining duration of the current stop authentication mode may be displayed in a screen display manner, and the specific manner may be set according to an application scenario, which is not limited in the embodiment of the present application.

Secondly, acquiring pedestrian flow images which are acquired by the image acquisition equipment and pass from the first direction and the second direction, determining a pedestrian flow rule of passing from the first direction and the second direction in the current application scene based on the images, determining the division of time periods in the application scene according to the rule, and determining pedestrian flow data of passing from the first direction and the second direction based on the pedestrian flow images in each time period.

In addition, in specific implementation, the first door opening request carries identification information of a user passing in a first direction, and the second door opening request carries identification information of a user passing in a second direction; the identification information may specifically be information such as employee number of the user, identification number of the user, name of the user, address, and the like.

In this case, the second identity authentication device 120 is further specifically configured to:

Specifically, one possible form of the first prompt message and the second prompt message may be "the door opening is successful for XX user".

In the embodiment of the present application, the first prompt information and the second prompt information both include identification information of the user, so that when a plurality of users wait to pass in a certain direction, the situation that the user a passes the identity authentication, but the user B passes the pass can be prevented.

In order to facilitate understanding of the bidirectional access control system provided in the embodiment of the present application, the bidirectional access control system will be described below with reference to a specific application scenario, taking the first identity authentication device 110 as a first face recognition device and the second identity authentication device 120 as a second face recognition device as an example.

Fig. 3 is a schematic diagram illustrating an application scenario of the system provided in the embodiment of the present application, where an entrance guard system capable of two-way passage is installed at an entrance and an exit of a company, a first face recognition device is installed in a first direction (a direction entering the company) of the two-way entrance guard system, a second face recognition device is installed in a second direction (a direction exiting the company), the first time length is set to 5 seconds, and the second time length is set to 60 seconds during a morning work hours period (e.g., between half-morning and half-night).

When an employee A enters a company from a first direction of a two-way access control, a first face recognition device collects face images of the employee A, the employee A is recognized based on the collected face images, whether the employee A is an employee of the company is verified, employee information of the employee is determined, after the employee A passes the recognition, the first face recognition device sends a first door opening request for the employee A to a second face recognition device, after the second face recognition device receives the first door opening request sent by the first face recognition device, the first door opening request is added to a door opening request queue, the second face recognition device sequentially controls a gate to be opened according to the arrangement sequence of the door opening requests in the door opening request queue, and after the first door opening request is turned, the gate is controlled to open the employee A. And after the gate is controlled to open the door for employee A, the gate is controlled to stop face recognition, and the time length for stopping face recognition is 60 seconds. During the period, the first face recognition device continuously performs face recognition on the staff who need to enter the company.

In addition, in this embodiment, after the gate is controlled by the second face recognition device to open the door for the employee a, the first prompt information of "successfully open the door for the employee a" needs to be sent to the first face recognition device, specifically, the first face recognition device may display the first prompt information, and may also broadcast the first prompt information through voice.

Similarly, when the employee B leaves the company from the second direction of the two-way access control, the second face recognition device collects the face image of the employee B, carries out face recognition on the employee B based on the collected face image, verifies whether the employee B is the employee of the company, determines the employee information of the employee, generates a second door opening request after the recognition is passed, adds the second door opening request into a door opening request queue, sequentially controls the gates to be opened according to the arrangement sequence of the door opening requests in the door opening request queue, and controls the gates to open the doors for the employee B when the second door opening request comes. And after the gate is controlled to open the door for the employee B, sending an instruction for stopping the recognition to the first face recognition device, wherein the time length for stopping the face recognition carried in the instruction is 5 seconds, and after the first face recognition device receives the instruction, stopping the face recognition and the time length for stopping the face recognition is 5 seconds.

In addition, after the second face recognition device controls the gate to open the door for the employee B, second prompt information of 'successfully opening the door for the employee B' is generated, and the second prompt information is displayed or broadcasted.

The two-way access control system that this application embodiment provided, first authentication equipment does not possess the authority that control access control equipment opened, and two current directions all open through second authentication equipment control access control equipment, have avoided like this when two current directions all have the user to pass, and access control equipment is reverse to be opened, perhaps, the appearance of the unable current condition of one of them direction user.

Corresponding to the bidirectional access control system provided in the embodiment of the present application, based on the same idea, an embodiment of the present application further provides a control method of a bidirectional access control, which is applied to a first identity authentication device in the bidirectional access control system, fig. 4 is one of method flow charts of the control method of the bidirectional access control provided in the embodiment of the present application, and the method shown in fig. 4 at least includes the following steps:

and 402, when the first identity authentication device is in an authentication mode, authenticating the identity of a user passing from the first direction of the two-way access control.

Generally, in order to prevent a user passing through the first direction and a user passing through the second direction from colliding, the users in both directions are not allowed to pass through simultaneously, and therefore, when the door access control device is controlled to open the door to the user passing through the first direction, the second authentication device enters the stop authentication mode, and when the door access control device is controlled to open the door to the user passing through the second direction, the first authentication device enters the stop authentication mode. The first authentication device authenticates a user passing from the first direction only when in the authentication mode.

In the embodiment of the application, the first identity authentication device arranged in the first direction is only responsible for identity authentication of the passing user in the first direction, and does not have the authority of controlling the opening of the access control device.

The first time length is determined by the second identity authentication device according to the traffic data of the people passing in the first direction and the second direction. In a specific implementation manner, since the traffic data of the first direction and the second direction in different time periods are different, the time periods can be divided according to the traffic data, and the specific values of the first time length in different time periods are different. When the second identity authentication device sends the instruction to the first identity authentication device, the specific value corresponding to the first time length in the time can be searched.

In other embodiments, the first time length may also be determined by the first identity authentication device, in this case, the first time length is not carried in the instruction for stopping the identity authentication, which is sent to the first identity authentication device by the second identity authentication device, and after the first identity authentication device receives the instruction sent by the second identity authentication device, the first time length may be directly obtained from itself. Because the values of the first time length in different time periods are different, when the first time length is obtained, the time period corresponding to the current time can be determined, and the value of the first time length corresponding to the time period can be searched.

In addition, after the first identity authentication device enters the identity authentication stopping mode, countdown operation is performed, so that a user passing from the first direction can know the current waiting time length according to countdown.

Specifically, in order to facilitate the user to know which user is opening the door in which direction, the second identity authentication device sends first prompt information to the first identity authentication device after controlling the access control device to open the door for the user passing in the first direction, so as to prompt that the door is opened successfully for the XX user. Therefore, in the embodiment of the present application, the first door opening request carries identification information of a user passing in a first direction;

correspondingly, after sending the first door opening request to the second identity authentication device arranged at the second direction of the two-way access control, the method provided by the embodiment of the application further comprises:

The method provided by the embodiment of the present application will be described below by taking the first identity authentication device and the second identity authentication device as face recognition devices and performing face recognition on a passing user as an example. Fig. 5 is a second flowchart of a method of controlling a bidirectional door access according to an embodiment of the present application, where the method shown in fig. 5 at least includes the following steps:

step 502, when the first face recognition device is in a face recognition mode, performing face recognition on a user passing in a first direction of the two-way access control; if the face recognition is passed, executing step 504, otherwise, continuing to execute step 502, and performing face recognition on the next user passing from the first direction.

Step 504, a first door opening request is sent to the second face recognition device.

The first door opening request carries identification information of a first direction and identification information of the user.

In step 506, the second face recognition device receives the first door opening request.

And step 508, adding the first door opening request to a door opening request queue by the second face recognition device, controlling the door control device to open according to the arrangement sequence of the door opening requests in the door opening request queue, and controlling the door control device to open the door of a user passing from the first direction when the first door opening request comes.

According to the control method of the bidirectional access control, the first identity authentication device does not have the permission of controlling the access control device to be opened, the two passing directions control the access control device to be opened through the second identity authentication device, and therefore the situation that the access control device is reversely opened or the user cannot pass in one direction when the two passing directions pass through by the user is avoided.
