detailed description

In order to make the objectives, technical solutions, and advantages of the present application clearer, some embodiments of the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, and are not used to limit the application.

The first embodiment of the present application relates to an access control system. As shown in FIG. 1, the access control system includes: a main control device 10, a door lock device 11, a cloud server 12, and at least one smart terminal 13; the main control device 10 is connected to the cloud server 12 and the door lock device 11, the smart terminal 13 is connected to the cloud server 12; the smart terminal 13 is used to send an unlock request to the main control device 10 through the cloud server 12 when in the first mode; the main control device 10 is used to When unlocking is requested, it is determined whether unlocking is permitted according to the unlocking request, and when it is determined that unlocking is permitted, the door lock device 11 is controlled to unlock. Among them, only one smart terminal 13 is shown in FIG. 1, but it is not limited thereto.

The implementation details of the access control system of this embodiment will be described in detail below. The following content is only provided for ease of understanding and is not necessary for implementing this solution.

The main control device 10 in this embodiment may be a small workstation, or may be an intelligent device such as a personal computer. The door lock device 11 may include a microcontroller, a mechanical lock, and a driving mechanism; the main control device 10 controls the door lock device 11 to unlock, specifically, the main control device 10 sends an unlock command to the microcontroller of the door lock device 11. When the controller receives the unlocking command, the mechanical lock is driven to open by the driving mechanism to realize the unlocking.

In an example, as shown in FIG. 2, there may be multiple communication modes between the cloud server 12 and the main control device 10, such as but not limited to the following two: wide area network WAN and narrowband Internet of Things NB-IOT. The communication method between the smart terminal 13 and the main control device can also be multiple. In addition to communicating based on the cloud server 13, it can also be based on short-range wireless transmission technology. Two short-range wireless transmission methods are shown in Figure 2. Bluetooth and wireless local area network WIFI; however, it is not limited to this, and other types of short-distance wireless transmission technologies such as infrared technology, microwave technology, etc. can be applied in this embodiment.

The smart terminal 13 may have a variety of different modes. In different modes, different communication paths are selected to send the unlock request to the main control device. In this embodiment, the smart terminal 13 may be in the first mode or the second mode.

When the smart terminal 13 is in the first mode, it sends an unlocking request to the cloud server 12 to send the unlocking request to the main control device 10 through the cloud server 12. When the cloud server 12 receives the unlocking request, it can choose any path of WAN or NB-IOT to send the unlocking request to the door lock device 11. In this way, when one of the paths is congested or cannot be connected, the other path can be selected to send the unlocking Request; so as to avoid affecting normal unlocking when one of the transmission paths is blocked or interrupted.

When the smart terminal 13 is in the second mode, it can send an unlock request to the main control device 10 based on the short-range wireless transmission technology; an independent WIFI device 14 (such as a router) is set in the WIFI path shown in FIG. To broaden the coverage of WIFI; however, it is not limited to this.

The door lock device 11 in this embodiment can be applied to various scenarios. For example, the door lock device 11 can be installed at the gates of public places such as movie theaters, factory warehouses, subways, etc.; or, it can also be installed on personal items such as safes. . Among them, when the door lock device 11 is installed on a movable device such as a safe, even if the movable device is stolen by criminals, it must be unlocked based on the master control device, and the movable device is stolen because it is far away from the master control device. The device cannot be connected with the main control device signal, so criminals cannot illegally unlock the mobile device by using software intrusion, which improves the security to a certain extent (in the prior art, when the short-range wireless communication technology is used to When the mobile device sends an unlock request, the microcontroller in the door lock device determines whether unlocking is allowed. Therefore, after the mobile device is not stolen, the microcontroller in the door lock device can be illegally unlocked by software intrusion) .

In this embodiment, the main control device 10 is configured to determine whether unlocking is permitted according to the unlocking request when receiving the unlocking request, and when it is determined that the unlocking is permitted, control the door lock device 11 to unlock. In an example, the master control device 10 may identify characteristic information according to the unlock request, and the characteristic information may include the identity information of the user who sent the unlock request; the master control device 10 obtains the access control authority corresponding to the user and at least determines whether it is allowed or not according to the obtained access control authority Unlock. Specifically, the master control device 10 may store the corresponding relationship between the user and the access control authority, and the master control device 10 obtains the corresponding access control authority of the user who sent the unlock request according to the corresponding relationship between the user and the access control authority. Among them, the user’s identity information can be, for example, the user’s account information as the only indicator of the user’s identity; the access control authority can be unlocking authority or no unlocking authority. When the user’s corresponding access control authority is unlocking authority, the master device It is determined that unlocking is allowed and the door lock device is controlled to unlock; when the user's corresponding access control authority is no unlocking authority, the master control device determines that unlocking is not allowed.

In another example, the characteristic information may include an unlocking password. The master control device 10 recognizes the unlocking password from the unlocking request, and determines whether the unlocking password is consistent with a preset standard password, and if it is consistent, it determines that unlocking is allowed.

In another example, the characteristic information may include the user's identity information and the unlocking password, and the master control device determines whether the unlocking password is consistent with the preset standard password when determining that the user's corresponding access control authority has unlocking authority; if If they are consistent, unlocking is allowed; otherwise, unlocking is not allowed.

It should be noted that this embodiment does not impose any restriction on the specific manner in which the master control device 10 determines whether to allow unlocking according to the unlocking request, and the above is only an example for description.

In this embodiment, the master control device determines whether unlocking is allowed, that is, the master control device 10 stores the core data for unlocking determination. The core data is the corresponding relationship between the user and the access control authority in the above example, the standard password, and the specific Unlocking judgment methods, etc.; in the prior art, cloud servers store these core data. Since the main control device in this case is equivalent to the edge node in the complex network structure, compared to the cloud server as the central node of the network, the edge node is more difficult to be illegally invaded, that is, the core data is safe in the edge node. The performance is higher, so this embodiment can improve the security of the access control system; in addition, the main control device as the edge node has to process relatively few services, and its processing speed will be relatively faster.

In an example, the permission type of the access control permission may include, but is not limited to, one or any combination of the following types: restricted location, restricted time, restricted access direction, and so on. Wherein, restricted location means that it has the unlocking authority only in a preset area; for example, the master control device 10 can be set to only allow the unlocking request of the smart terminal 13 to be received based on the short-range wireless technology, that is, the smart terminal 13 can only be unlocked in the vicinity The unlock request can only be sent within the distance (the coverage of short-range wireless technology). Time restriction means that the unlocking authority is only available within a preset time period; for example, the master control device 10 can be set to the preset time period, and the master control device 10 records the receiving time of the unlock request or the characteristic information of the unlock request Contains the sending time of the unlocking request recorded by the smart terminal 13. If the receiving time or the sending time is within a preset time period, unlocking is allowed. Restricted direction of passage means that only users are allowed to enter or leave. For an access control system that can pass in both directions, if there are two gate channels, corresponding to two directions of passage; after the user sends an unlock request, the master device will only unlock The gate in the direction that allows the user to pass.

It should be noted that, in addition to online unlocking, the access control system of this embodiment also supports offline unlocking such as NFC, fingerprint password, or digital password. That is, the door lock device can be equipped with NFC module, fingerprint recognition module, and input module as needed. And so on, so as to achieve offline unlocking.

The second embodiment of the present application relates to an access control system. The second embodiment is roughly the same as the first embodiment. The difference is that, in the second embodiment, please refer to FIG. 1 or FIG. Set up an event to notify the master control device to take action when a preset event occurs.

Specifically, the cloud server 12 may send an early warning signal to the main control device 10 when it detects that a preset event occurs, and the main control device 10 is also configured to enter the preset control mode when receiving the early warning signal. Among them, the cloud server 12 can monitor preset events through the network. The preset events can be some high-risk events, such as floods, earthquakes, celestial body impacts, fires and other major disasters; the preset control mode can be but not limited to the following methods: directly control the door The lock device is unlocked, or unconditionally unlocked; among them, unconditional unlock means that as long as the unlock request sent by the smart terminal 13 is received, the door lock device 11 is controlled to unlock. Or, in the preset control mode, the main control device 10 can also detect whether there is someone inside the door lock device 11, and if there is someone, control the door lock device 11 to unlock, wherein the main control device 10 can be pre-installed on the door lock Multiple sensors on the inner side of the device 11 are used to detect whether there are people inside the door lock device 11; the inner side of the door lock device 11 can be understood as, for example, the door lock device 11 is installed on the gate of a warehouse, and the inner side of the door lock device 11 refers to The internal space of the warehouse.

For example, when a flood disaster occurs, relevant departments may publish flood disaster information on certain network platforms, or network users may promptly notify other netizens on certain network platforms; the cloud server 12 can be preset to Information channels such as a network platform are monitored. When relevant information about a preset event is monitored, an early warning signal is sent to the main control device 10.

For another example, the door lock device 11 is installed on the gate of a warehouse, and various sensors are installed in a preset area around the warehouse to detect the surrounding environment. Various sensors include, for example, temperature detectors, smoke detectors, etc.; When a fire occurs in the area, various sensors will send out abnormal signals; when the cloud server 12 detects these abnormal signals, it determines that a preset event has occurred, and sends an early warning signal to the main control device 10.

The foregoing is only an example. This embodiment does not impose any restrictions on the specific types of preset events and their corresponding preset control modes, which can be set as required. In this embodiment, the cloud server can actively monitor the preset event, and notify the master control device when the preset event occurs, so that the master control device enters the preset control mode, which can meet the needs of more practical application scenarios.

In an example, the cloud server 12 includes a plurality of distributed sites; each distributed site is used to send an early warning signal to the main control device 10 when a preset event is detected. The main control device 10 is configured to enter a preset control mode when receiving an early warning signal sent by each distributed station. That is, the cloud server 12 is a distributed structure, and the master control device 10 enters the preset control mode only when it receives early warning signals from multiple distributed sites at the same time, so as to avoid monitoring errors of individual distributed sites and causing misjudgments as much as possible , Higher reliability.

The third embodiment of the present application relates to an access control system. The third embodiment is roughly the same as the first embodiment. The difference is that, as shown in FIG. 3, the smart terminal 13 may include an administrator terminal 13-1 and a common user terminal. 13-2. The number of administrator terminals 13-1 and ordinary user terminals 13-2 in Fig. 3 is only an example, and is not limited thereto. If the ordinary user terminal 13-2 does not have the unlocking authority when an emergency event occurs, the ordinary user terminal 13-2 can send an emergency unlock request to the administrator terminal 13-1; the administrator terminal 13-1 is used to request the emergency unlock The authentication is performed and the authenticated emergency unlocking request is sent to the main control device 10; the main control device 10 controls the door lock device 11 to unlock after receiving the authenticated emergency unlocking request. Among them, FIG. 3 only illustrates the transmission path for the ordinary user terminal 13-2 to send the emergency unlock request through the administrator terminal 13-1 in the event of an emergency, but it is not limited to this. The ordinary user terminal 13-2 The unlocking request can also be sent to the main control device 10 through the cloud server 12 or based on the short-range wireless transmission technology.

In this embodiment, the access control authority corresponding to the normal user terminal 13-2 and the administrator terminal 13-1 are different. The administrator terminal 13-1 has a higher access control authority, that is, the master control device 10 can be set to allow unlocking as long as it receives an emergency unlock request authenticated by the administrator terminal 13-1. The ordinary user terminal 13-2 does not have the unlocking authority of the door lock device, or the access authority of the ordinary user terminal 13-2 includes restricted types such as location restriction or time restriction, which causes the ordinary user terminal 13 -2 does not have unlock permission. Therefore, when an ordinary user terminal 13-2 finds that an emergency event occurs, it needs to request unlocking from the master device 10 through the administrator terminal 13-1.

For example, the door lock device 11 is installed on the gate of a warehouse, the access control account used by the warehouse administrator corresponds to the administrator terminal 13-1, and the access control account used by the warehouse cargo handler corresponds to the ordinary user terminal 13-2; The access control authority of personnel includes the type of time restriction, and the unlocking authority is only available during working hours (for example, the time period from 8 am to 4 pm). When warehouse cargo handlers find that an emergency event occurs during non-working hours and the warehouse manager is not on site, the emergency event is for example someone calling for help in the warehouse. The warehouse cargo handler can send an emergency unlock request to the normal user terminal 13-2. After the warehouse administrator’s administrator terminal 13-1 and the warehouse administrator’s administrator terminal 13-1 authenticate the emergency unlock request, it sends the certified emergency unlock request to the master control device 10, and the master device 10 receives it After the authenticated emergency unlock request, the door lock device 11 is controlled to unlock. Among them, when the administrator terminal 13-1 receives the emergency unlock request, it can automatically authenticate and send the certified emergency unlock request to the main control device 10; or it can remind the warehouse administrator to perform manual authentication and send the certified emergency unlock request. The unlock request is sent to the master control device 10.

It should be noted that the third embodiment may also be an improvement on the basis of the second embodiment.

The fourth embodiment of the present application relates to an access control system. The fourth embodiment is substantially the same as the first embodiment. The difference is that in the fourth embodiment, as shown in FIG. 4, the access control system further includes a smart terminal 13 The auxiliary positioning device 15; the smart terminal 13 is also used to obtain the positioning information of the smart terminal 13 through the auxiliary positioning device 15 when in the first mode, and the unlock request includes the positioning information.

Among them, the auxiliary positioning device 15 is, for example, but not limited to satellites, and the smart terminal 13 can, but is not limited to, perform GPS positioning to obtain positioning information; all types of auxiliary positioning devices 15 that enable the smart terminal 13 to obtain positioning information belong to the protection of this embodiment. range.

When the smart terminal 13 is in the first mode, it sends an unlock request to the main control device 10 through the cloud server 12, which can realize remote unlocking; however, for some users, the access control authority is set and the location is restricted; The positioning device 15 obtains the user's positioning information, and integrates the positioning information into the unlock request and sends it to the master control device; thus, the master control device 10 can make an unlock permission judgment for these location-restricted users based on the unlock request sent by the cloud server 12.

It should be noted that the fourth embodiment may also be an improvement on the basis of the third embodiment.

The fifth embodiment of the present application relates to an access control system. The fifth embodiment is substantially the same as the fourth embodiment. The difference is that in the fifth embodiment, as shown in FIG. 5, the access control system further includes The storage device 16 of 10; the master control device 10 is also used to generate an unlock record of the unlock request after judging whether unlocking is permitted according to the unlock request, and store the unlock record in the storage device 16; wherein the unlock record includes at least: master control device 10 The identity information of the user who sent the unlock request identified according to the unlock request, and whether the unlock was successful.

In this embodiment, whether the unlocking is successful in the unlocking record may be: the result determined by the master control device 15 according to the access control authority, that is, whether unlocking is permitted or not allowed; wherein, when the master control device 10 determines that unlocking is permitted and controls the door After the lock device 11 is unlocked, the door lock device 11 may also send feedback information indicating successful unlocking to the main control device 10, and when the main control device 10 receives the feedback information indicating successful unlocking, it determines that the unlocking is successful. The unlock record in this embodiment may also include the time when the master control device receives the unlock request, the time when the door lock device is controlled to unlock (if unlocking is allowed), etc., which can be set as required.

In an example, the permission type of the access permission can also include anonymous permission; the master control device 10 first identifies whether the user’s access permission includes anonymous permission, if the user’s access permission includes anonymous permission, then no unlock record will be generated; if the user’s If the access control authority does not include the anonymous authority, an unlock record is generated. That is, for some users with anonymous permissions, the master control device 10 will not record the process of their unlock request. In this embodiment, the types of user access control permissions are further enriched, which can meet the requirements of more practical application scenarios.

The sixth embodiment of the present application relates to an unlocking method of an access control system, which is applied to the main control device in the access control system. For the access control system, please refer to Figure 1 or Figure 2. The access control system also includes a cloud server, a door lock device and at least one smart terminal ; The smart terminal is used to send an unlock request to the main control device through the cloud server when in the first mode.

FIG. 6 shows a flowchart of the unlocking method of the access control system in this embodiment, and the details are as follows.

Step 101: Judge whether an unlock request is received; if yes, go to step 102; if not, repeat step 101.

Step 102: Determine whether to allow unlocking according to the unlock request; if yes, go to step 103; if not, end.

Step 103: Control the door lock device to unlock.

In an example shown in Fig. 7, step 102 specifically includes the following sub-steps:

Sub-step 1021, identifying characteristic information according to the unlock request; wherein the characteristic information includes at least the identity information of the user who sent the unlock request.

Sub-step 1022: Obtain the access control authority corresponding to the user.

In sub-step 1023, it is judged whether unlocking is allowed at least according to the acquired access control authority.

In this embodiment, the master control device determines whether unlocking is allowed. Therefore, the master control device stores the core data used for unlocking determination. In the prior art, the cloud server stores these core data (in the prior art, the cloud server Determine whether to allow unlocking); since the master control device in this case is equivalent to the edge node in the complex network structure, compared to the cloud server as the central node of the network, the edge node is more difficult to be illegally invaded, that is, the core data The security in the edge node is higher, so this embodiment can improve the security of the access control system; in addition, the main control device as the edge node has to process relatively few services, and its processing speed will be relatively faster.

It is not difficult to find that this embodiment is a method example corresponding to the first embodiment, and this embodiment can be implemented in cooperation with the first embodiment. The related technical details mentioned in the first embodiment are still valid in this embodiment, and in order to reduce repetition, they will not be repeated here. Correspondingly, the related technical details mentioned in this embodiment can also be applied in the first embodiment.

The seventh embodiment of the present application relates to an unlocking method of an access control system. The seventh embodiment is roughly the same as the sixth embodiment, except that the master control device can receive the early warning signal sent by the cloud server when a preset event occurs. And take measures.

Step 201, determine whether an unlock request is received; if yes, go to step 202; if not, repeat step 201.

Step 202, judge whether to allow unlocking according to the unlock request; if yes, go to step 203; if not, go to 204.

Step 203: Control the door lock device to unlock.

In step 204, it is determined whether an early warning signal sent by the cloud server when a preset event is detected is received; if yes, go to step 205; if not, step 204 is repeated.

Step 205: Enter a preset control mode.

Among them, step 201 to step 203 are substantially the same as step 101 to step 103 in the sixth embodiment, and will not be repeated here. The difference is that step 204 to step 205 are also included. It should be noted that steps 201 to step 203 are used to achieve access control unlocking, and steps 204 to step 205 are used to achieve access control when a preset event occurs. The order of execution of the two is not limited, that is, to achieve access control unlocking and to achieve preset event occurrence The access control at the time can be executed concurrently, which is only schematically illustrated in Figure 8.

In this embodiment, the cloud server can actively monitor the preset event, and notify the master control device when the preset event occurs, so that the master control device enters the preset control mode; that is, the master control device can use when the preset event occurs Pre-set access control can meet the needs of more practical application scenarios.
