Description

Bidirectional access control system and control method thereof

Technical Field

Background

Currently, with the improvement of people's safety consciousness, an access control system for managing personnel to enter and exit is increasingly applied to various fields such as daily life, travel and work, for example, the access control system can be applied to the entry and exit management of communities, companies, subway stations, parks and other scenes.

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

Therefore, the control system of the two-way access control in the prior art can be used for the situation that the access control equipment is opened reversely or one of the users cannot pass.

For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The following describes in detail the bidirectional entrance guard control system and the control method thereof provided in the embodiments of the present application with reference to the drawings.

Fig. 1 is a schematic structural diagram of a bidirectional entrance guard control system provided in an embodiment of the present application, and as shown in fig. 1, the system includes a first identity authentication device 110 and a second identity authentication device 120; the first identity authentication device 110 is connected with the second identity authentication device 120, the second identity authentication device 120 is connected with the access control device of the two-way access control, and the second identity authentication device 120 controls the access control device to be opened. In a 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 identity authentication device 110 is configured to authenticate the identity of a user passing through the bidirectional channel in a first direction, and send a first door opening request to the second identity authentication device 120 after the authentication is passed; the first door opening request is used for requesting a user passing in a first direction to open a door, and the first door opening request carries identification information in the first direction;

the second identity authentication device 120 is configured to receive a first door opening request, add the first door opening request to a door opening request queue, authenticate the identity of a user passing through the two-way entrance guard in a second direction, add the second door opening request to the door opening request queue after authentication is passed, and control the entrance guard device of the two-way entrance guard to open the door for the user passing through the first direction or the second direction according to the arrangement sequence of the door opening requests in the door opening request queue; the second door opening request is used for requesting to open a door for a user passing in a second direction, and the second door opening request carries identification information in the second direction.

The identification information of the first direction and the second direction may be a direction name or a number. In addition, in the embodiment of the application, any one direction of the two-way access control can be used as a first direction, and the other direction is correspondingly used as a second direction.

In this embodiment of the present application, the first identity authentication device 110 does not have the authority to control the opening of the access control device, and both passing directions control the opening of the access control device through the second identity authentication device 120, so that the situation that when both passing directions have the user to pass, the access control device is reversely opened, or the user cannot pass 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 a specific embodiment, if the first authentication device 110 and the second authentication device 120 are both face recognition devices, in this embodiment of the present application, the first authentication device 110 is specifically configured to:

collecting face images of users passing from a first direction, and carrying out identity authentication on the users based on the face images;

the second authentication device 120 is specifically configured to:

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

In a specific embodiment, based on a specific application scenario of the two-way access control, the background management platform may issue personnel information with a passing right to the first identity authentication device 110 and the second identity 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 a specific implementation, whether the first identity authentication device 110 or the second identity authentication device 120 collects a face image, extracts a face feature in the face image, calculates a similarity value of the face feature and each face feature stored in the face feature, detects whether a face feature with the similarity value being greater than or equal to a set threshold exists, and if so, passes the identity authentication of the user.

Note that, in the embodiment of the present application, in the second authentication device 120, the first door opening request and the second door opening request are both 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, where the earlier the acquisition time, the more forward the arrangement in the request queue. Accordingly, in this case, the second authentication device 120 is specifically configured to:

and determining arrangement positions of the first door opening request and the second door opening request in a 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 authentication device 120 may add the acquired door opening request to the end position of the door opening request queue every time a door opening request is acquired, or may add the door opening request acquired in the period of time to the door opening request queue every time a set time interval is set.

For ease of understanding, the following examples are presented.

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 identity authentication device 120 receives the first door opening request 3 sent by the first identity authentication device 110 in 31 min 20 seconds at 9 am, generates the second door opening request 2 in 31 min 21 seconds at 9 am, and determines from the acquisition time of the first door opening request 3 and the second door opening request 2, 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 adds the first door opening request 3 and the second door opening request 2 to the door opening request queue according to the determined positions, and the arrangement of the door opening request queue formed by the second identity authentication device is shown in fig. 2 (a).

Of course, in addition to 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 may be determined according to the traffic of people in the first direction and the second direction, and the first door opening request and the second door opening request may be 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:

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

The time periods corresponding to the time periods may be equal or unequal, and the division of the time periods may be divided according to traffic data passing in the first direction and the second direction in an application scenario corresponding to the two-way access control system. For example, if the two-way access control system is applied to company access management, the traffic flow of people entering the company is obviously more than the traffic flow of people exiting the company in the working period, and the traffic flow of people exiting the company is obviously more than the traffic flow of people entering the company in the working period. Thus, one may take 7:30-9:30 as a time period, 9:30-12:00 as a time period, 12:00-1:30 as a time period, 1:30-5:30 as a time period, 5:30-6:30 as a time period, and 6:30 as a time period to 7:30 as a time period in the next morning from 6:30 to 7:30 as a time period in the next morning. Of course, the time periods divided herein are merely exemplary and are not to be construed as limiting the embodiments of the present application.

In the specific implementation, when the arrangement rule is determined according to the traffic data passing in the first direction and the second direction in each time period, the direction with more traffic and the direction with less traffic in the time period can be arranged according to the set proportion.

For example, continuing with the above example, during the period of time 7:30-9:30, the first direction (direction of entering the company) is significantly more people than the second direction (direction of exiting the company), in which case at least 5 first door opening requests may be inserted into the door opening request queue every consecutive order in order to relieve traffic pressure in the first direction without delaying the staff entering the company. One possible arrangement is shown in fig. 2 (b). In the queuing 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 am, no obvious difference exists between the traffic data passing in the first direction and the traffic data passing in the second direction, 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 this embodiment of the present 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 may be preset based on the traffic rules in the application scenario, so that the arrangement rules corresponding to the time periods are directly called in the corresponding time periods to perform the arrangement of the first door opening request and the second door opening request.

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

After the second door opening request is generated, the second identity authentication device 120 determines whether at least five first door opening requests have been continuously inserted into the door opening request queue from the last generation of the second door opening request to the current moment, if yes, the second door opening request generated at the current moment is added to the end position of the door opening request queue; otherwise, continuing to add the received first door opening request to the door opening request queue until counting is started from the generated second door opening request, and adding the second door opening request to the door opening request queue after five first door opening requests continuously exist in the door opening request queue.

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

In the embodiment of the application, the acquired first door opening requests and second door opening requests are arranged according to the arrangement rules corresponding to the time periods by setting the arrangement rules of the first door opening requests and the second door opening requests in the different time periods, so that users in the traffic peak direction can be allowed to pass continuously as far as possible, the traffic pressure in the traffic direction in the traffic peak period can be relieved, the traffic efficiency in the direction is ensured, and the waiting time of the users in the direction is reduced.

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

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

and after controlling the access control equipment to open the door for the user passing in the first direction, controlling the access control equipment to execute the operation of entering the stop authentication mode, wherein the time length of entering the stop authentication mode is the second time length.

Specifically, when the user passes through the second direction, the second identity 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, the door opening request is added to a door opening request queue, the second identity authentication device 120 controls the door access device to open according to the arrangement sequence of the door opening requests in the door opening request queue, when the second door opening request is received, the second identity authentication device 120 controls the door access device to open the door of the user passing through the second direction, and in order to prevent collision in the process that the user passes through the second direction, the user is not allowed to pass through the first direction, so that an authentication stopping instruction can be sent to the first identity authentication device 110, after the first identity authentication device 110 receives the instruction, the operation of entering the authentication stopping mode is executed, and when the time length of entering the authentication stopping mode reaches the first time length, the identity authentication stopping mode is entered 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 a certain direction of the two-way entrance guard is a traffic peak period 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 authentication stopping mode can be prolonged, so that a user in the traffic peak period can continuously pass, and the traffic pressure in the direction is relieved. Because the traffic data passing from the first direction and the second direction are different in different time periods, the values of the first time length and the second time length are different for different time periods.

For example, continuing to use the example, in the time period of 7:30-9:30, the number of users passing from the first direction is larger, and the number of users passing from the second direction is smaller, so that in order to relieve the passing pressure in the first direction, the users passing in the first direction need to pass continuously as much as possible, and therefore the value of the second time length can 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 be all determined by the second identity authentication device 120. Thus, the second authentication device 120 is also specifically configured to:

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

Specifically, when dividing the time period, a time point at which the traffic data passing from the first direction and the second direction changes significantly may be taken as a division point of the time period. For example, continuing the above example, for the two-way entrance guard system applied to the gate of the company, the entrance guard system is at the peak of work in a period of 7:30-9:30, the traffic of people entering the company is obviously more than the traffic of people exiting the company, and after 9:30, no great difference exists between the traffic of people entering the company and the traffic of people exiting the company, so that 9:30 can be used as a dividing point of the period.

In the implementation, the values of the first time length and the second time length can be determined according to the ratio of the traffic data passing from the first direction to the traffic data passing from the second direction in each time period. For example, if the ratio of the traffic passing from the first direction to the traffic passing from the second direction is 10:1 in a certain period of time, 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 traffic of people passing from the first direction is significantly more than the traffic of people passing from the second direction, the first direction is determined as the main traffic direction of the two-way 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 identity authentication device to enter the authentication stopping mode is longer, and the user in the first direction can continuously pass within the time period, thereby relieving the traffic pressure in the first direction; similarly, if the traffic of people passing from the second direction is significantly greater than the traffic of people passing from the first direction in a certain period of time, the second direction is determined to be the main traffic direction of the two-way entrance guard system, and the first direction is the auxiliary traffic direction.

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

In this embodiment of the present application, the specific values of the first time length and the second time length in each time period may be determined by the second identity authentication device 120 in a unified manner, 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 when the second authentication device 120 sends an instruction to the first face device to stop authentication, the first time length still needs to be carried in the instruction, so that the size of data sent by the second authentication device 120 to the first authentication device 110 may be reduced, thereby reducing data transmission delay and improving data transmission speed.

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

after controlling the access control equipment to open a door for a user passing in a 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 the stop authentication mode, and a first time length of entering the stop authentication mode is stored in the first authentication device 110;

In this case, the first authentication device 110 is also specifically configured to:

In this implementation manner, a series of values with different sizes may be stored in the first identity authentication device 110 and the second identity authentication device 120 in advance, where the first identity authentication device 110 may select, according to a set rule, a value of a first time length from the pre-stored values, and the second identity authentication device 120 may select, according to the set rule, a value of a second time length from the pre-stored values, according to the first direction and the second direction, respectively.

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

In addition, it should be noted that, in the embodiment of the present application, whether the first authentication device 110 or the second authentication device 120, after entering the stop authentication mode, in order to facilitate the current waiting user to know that the waiting is still needed, the countdown operation is performed. Specifically, the remaining duration of the current identity authentication stopping mode may be broadcasted in a voice broadcast mode, or the remaining duration of the current identity authentication stopping mode may be displayed in a screen display mode, and the specific form may be set according to an application scenario, which is not limited in this embodiment of the present application.

Specifically, the above determination of the traffic data passing from the first direction and the second direction in each time period may be at least implemented in the following two ways:

first, acquiring historical traffic data of an application scene corresponding to a two-way access control system in a period of time, determining division of time periods in the application scene based on the historical traffic data, and determining traffic data passing from a first direction and a second direction in each time period.

Secondly, acquiring people flow images passing through the first direction and the second direction and acquired by the image acquisition equipment, determining the people flow rule passing through 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 the current people flow data passing through the first direction and the second direction based on the people flow images in each time period.

In addition, in the implementation, the first door opening request carries identification information of the user passing in the first direction, and the second door opening request carries identification information of the user passing in the second direction; the identification information can be specifically information such as employee numbers of users, identification card numbers of the users, names and addresses of the users and the like.

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

after controlling the access control equipment to open a door for a user passing in a first direction, sending first prompt information to the first identity authentication equipment so that the first identity authentication equipment displays the first prompt information or broadcasts the first prompt information; the first prompt message is used for prompting successful door opening of the identified user passing from the first direction;

after controlling the access control equipment to open the door for the user passing in the second direction, generating second prompt information, and displaying the second prompt information or broadcasting the second prompt information; the second prompt message is used for prompting successful door opening of the identified user passing from the second direction.

Specifically, one possible form of the first prompt information and the second prompt information may be "successful in opening the door to the XX user".

In this embodiment of the present application, the first prompt information and the second prompt information each include identification information of the user, so that when a plurality of users wait for passing in a certain direction, the user a can be prevented from passing the identity authentication, but the user B passes.

In order to facilitate understanding of the bidirectional entrance guard control system provided in the embodiments of the present application, the following description will take the first identity authentication device 110 as a first face recognition device, the second identity authentication device 120 as a second face recognition device as an example, and the bidirectional entrance guard control system is described in connection with a specific application scenario.

As shown in fig. 3, an application scenario of the system provided in the embodiment of the present application is schematically shown, where a two-way access control system is installed at a corporate entrance and exit, a first face recognition device is installed in a first direction (a direction of entering a corporation) of the two-way access control system, a second face recognition device is installed in a second direction (a direction of exiting the corporation), and a first time length is set to 5 seconds and a second time length is set to 60 seconds in a morning shift time period (e.g., between seven and one half in the morning).

When an employee A enters a company from a first direction of a two-way entrance guard, a first face recognition device collects face images of the employee A, identifies the employee A based on the collected face images, verifies whether the employee A is an employee of the company, determines employee information of the employee, sends a first door opening request for the employee A to a second face recognition device after the identification is passed, adds the first door opening request to a door opening request queue after the second face recognition device receives the first door opening request sent by the first face recognition device, and sequentially controls a gate to be opened according to the arrangement sequence of all door opening requests in the door opening request queue, and controls the gate to open the door for the employee A after the first door opening request is completed. And after the control gate opens the door for the staff A, the control gate stops the face recognition, and the time length for stopping the face recognition is 60 seconds. During the period, the first face recognition device continuously carries out face recognition on staff needing to enter the company.

In addition, in this embodiment, after the second face recognition device controls the gate to open the door for the employee a, a first prompt message of "successfully opening the door for the employee a" needs to be sent to the first face recognition device, and specifically, the first face recognition device may display the first prompt message, or may broadcast the first prompt message through voice.

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

In addition, after the control gate opens the door for the staff B, the second face recognition device generates a second prompt message of "successfully opening the door for the staff B", and displays or broadcasts the second prompt message.

According to the bidirectional access control system provided by the embodiment of the application, the first identity authentication equipment does not have the authority for controlling the access control equipment to be opened, and the access control equipment is controlled to be opened by the second identity authentication equipment in two passing directions, so that the situation that when two passing directions are all provided with users to pass through, the access control equipment is reversely opened, or one of the access control equipment cannot pass through is avoided.

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

step 402, when the first identity authentication device is in an authentication mode, identity authentication is performed on a user passing through a first direction of the two-way entrance guard.

Step 404, if the authentication is passed, sending a first door opening request to a second identity authentication device arranged in a second direction of the two-way door access, so that the second identity authentication device adds the first door opening request into a door opening request queue, controlling the door access device of the two-way door access to open according to the arrangement sequence of the door opening requests in the door opening request queue, and controlling the door access device to open the door of a user passing in the first direction when the first door opening request is rotated; the first door opening request is used for requesting a user passing in a first direction to open a door, and the first door opening request carries identification information in the first direction.

Generally, in order to prevent collision between a user passing from a first direction and a user passing from a second direction, the users in both directions are not allowed to pass simultaneously, so when the access control device is controlled to open a door for the user passing in the first direction, the second identity authentication device enters a stop authentication mode, and when the access control device is controlled to open a door for the user passing in the second direction, the first identity authentication device enters the stop authentication mode. The first authentication device authenticates a user who passes from the first direction only when in the authentication mode.

In the embodiment of the application, the first identity authentication equipment arranged in the first direction is only responsible for carrying out identity authentication on the user passing in the first direction, does not have the authority of controlling the opening of the access control equipment, and after the passing user passes the identity authentication, the second identity authentication equipment arranged in the second direction of the two-way access control equipment controls the access control equipment to open the door for the user passing in the first direction.

Generally, after the second identity authentication device controls the entrance guard to open the door for the user passing in the first direction, the second identity authentication device controls the second identity authentication device to enter a stop identity authentication mode, and similarly, after the second identity authentication device controls the entrance guard to open the door for the user passing in the second direction, the first identity authentication device is required to enter the stop identity authentication mode, and specifically, the stop authentication command can be sent to the first identity authentication device by the second identity authentication device.

Therefore, the method provided by the embodiment of the application further comprises the following steps:

receiving an authentication stopping instruction sent by the second identity authentication equipment, and executing an operation of entering an authentication stopping mode according to the instruction of the instruction; the instruction carries a first time length for the first identity authentication device to enter the authentication stopping mode.

The first time length is determined by the second identity authentication equipment according to the traffic data of the people passing in the first direction and the second direction. In a specific embodiment, because the traffic data of the first direction and the second direction are different in different time periods, 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, a specific value corresponding to the first time length in the time can be searched.

Of course, in other embodiments, the first time length may also be determined by the first authentication device, in this case, the instruction for stopping the authentication sent by the second authentication device to the first authentication device does not carry the first time length, and after the first authentication device receives the instruction sent by the second authentication device, the first time length may be directly acquired from the first authentication device. Because the values of the first time periods in different time periods are different, when the first time period is acquired, the time period corresponding to the current moment can be determined, and then the value of the first time period corresponding to the time period is searched.

In addition, when the first authentication device enters the stop authentication mode, a countdown operation is performed so that the user passing from the first direction knows the current waiting time period according to the countdown.

Specifically, in order to facilitate the user to know which user is going to open 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 going in the first direction, so as to prompt that the door is successfully opened for the XX user. Therefore, in the embodiment of the present application, the first door opening request carries identification information of the user passing in the first direction;

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

receiving first prompt information sent by second identity authentication equipment, and displaying the first prompt information or broadcasting the first prompt information; the first prompt message is used for prompting successful door opening of the identified user passing from the first direction.

The identification information of the user can be a work number, a card number, a house number, an identity card number and the like. One possible form of the first prompt may be "successful opening of the door to the XX user".

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

step 502, when a first face recognition device is in a face recognition mode, performing face recognition on a user passing through a first direction of a two-way entrance guard; if the face recognition passes, step 504 is performed, otherwise step 502 is continued to perform face recognition on the next user passing from the first direction.

Step 504, a first door opening request is sent to a 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.

In step 508, the second face recognition device adds the first door opening request to the door opening request queue, and controls the door access device to open according to the arrangement sequence of the door opening requests in the door opening request queue, and when the first door opening request is received, controls the door access device to open the door for the user passing from the first direction.

Step 510, the second face recognition device controls itself to enter a mode of stopping face recognition, and sends prompt information for indicating that the door opening for the user is successful to the first face recognition device.

In step 512, the first face recognition device receives the prompt information, and displays or broadcasts the prompt information.

It should be noted that, the method provided in the embodiment of the present application may implement each function of the first identity authentication device in the two-way access control system in the embodiment shown in fig. 1 to 3, where the specific implementation manner of each step may refer to the above embodiment, and the embodiment of the present application is not repeated.

According to the control method for the bidirectional entrance guard, the first identity authentication equipment does not have the right of controlling the entrance guard to open, and the entrance guard is controlled to open through the second identity authentication equipment in two passing directions, so that the situation that when two passing directions are all through by users, the entrance guard is opened reversely, or one of the two passing directions cannot be through by the users is avoided.

Corresponding to the bidirectional entrance guard control system provided in the embodiment of the present application, based on the same idea, the embodiment of the present application further provides a bidirectional entrance guard control method, which is applied to the second identity authentication device in the bidirectional entrance guard control system, fig. 6 is a third flowchart of a method of the bidirectional entrance guard control method provided in the embodiment of the present application, and the method shown in fig. 6 at least includes the following steps:

In the embodiment of the application, the users in the first direction and the second direction enter and exit through the same channel, so that in order to prevent collision, only the users in one direction can be allowed to pass at the same time, and therefore after the door is opened for the user in one direction, the other direction needs to enter a stop identity authentication mode. Therefore, after controlling the access control device to open the door for the user passing in the second direction, the method provided by the embodiment of the application further comprises the following steps:

sending an authentication stopping instruction to a first identity authentication device arranged in a first direction of the two-way access control, so that the first identity authentication device performs an operation of entering an authentication stopping mode after receiving the instruction; the instruction carries a first time length for the first identity authentication device to enter the authentication stopping mode.

Of course, if the second authentication device controls the access control device to open the door to the user passing in the first direction, the second authentication device needs to enter the stop authentication mode. Therefore, in the embodiment of the application, after controlling the access control device to open the door for the user passing in the first direction, the method further includes the following steps:

In this embodiment of the present application, the first time length is determined by the second identity authentication device, and because the traffic data of the first direction and the second direction are different in different time periods, the time periods may be divided according to the traffic data of the first direction and the second direction in different time periods, and the values of the first time length and the second time length in each time period may be determined respectively. In particular implementations, the first time period may be determined by:

determining traffic data passing from the first direction and the second direction in each time period; determining the value of the first time length in each time period according to the people flow data; wherein the time period is divided based on traffic data passing from the first direction and the second direction.

Of course, in some embodiments, the first time length may also be determined by the first authentication device, so that the instruction for stopping authentication sent to the first authentication device will not carry the first time length, thereby reducing the data transmission amount, reducing the data transmission delay, and improving the data transmission efficiency.

Likewise, in practice, the second length of time may be determined by:

determining traffic data passing from the first direction and the second direction in each time period; determining the value of the second time length in each time period according to the people flow data; wherein the time period is divided based on traffic data passing from the first direction and the second direction.

In addition, in the embodiment of the present application, the second door opening request carries identification information of the user passing in the second direction; therefore, after controlling the access control device to open the door for the user passing in the second direction, the method provided by the embodiment of the application further includes the following steps:

generating a second prompt message, and displaying the second prompt message or broadcasting the second prompt message; the second prompt message is used for prompting successful door opening of the identified user passing from the second direction.

In addition, the first door opening request sent by the first identity authentication equipment carries identification information of the user passing in the first direction; therefore, after controlling the access control device to open the door for the user passing in the first direction, the method provided by the embodiment of the application further includes the following steps:
