[0001] The present invention relates to the field of security technology, and in particular to a substation security system based on 5G communication. Background Art

[0002] The substation is an important infrastructure. Its performance not only directly affects the normal guarantee of people's livelihood electricity consumption, but also, considering its strong power properties, it will cause a great security threat if the substation equipment cannot be properly protected. Therefore, corresponding security measures are indispensable.

[0003] At present, the common security measures for substations are to set up a security room and have manual duty. This method has high requirements on the working status of the duty personnel, and there are many areas that need to be paid attention to. It is not only time-consuming and labor-intensive, but also difficult to achieve comprehensive monitoring. This traditional form of community protection alone obviously cannot meet the security needs of such important infrastructure. Therefore, it is necessary to set up an automated intelligent security system in key areas to achieve comprehensive and real-time security protection, and unmanned duty can also be achieved. Chinese patent publication number CN110853273B, the publication date is October 26, 2021, and the name is "Substation Security System". A substation security system is disclosed, including a controller and an electronic lock, a camera unit, an authentication unit and a server respectively connected to the controller signal, and mutually isolated power equipment rooms, inspection rooms and security rooms are set up. Through personnel detection and identification, irrelevant personnel can not access power equipment in a short time. However, the system provided by this patent still has the problem that the verification method for personnel is single and not flexible enough, and safety and door opening convenience cannot be taken into account. Summary of the invention

[0004] The present invention overcomes the problems of the prior art that the way of controlling the entry and exit of personnel is not flexible enough when performing security protection on substations, and that security and convenience cannot be taken into account at the same time, and provides a substation security system based on 5G communication. By setting up image detection equipment and access controllers for information collection and door opening and closing control, and cooperating with authentication control equipment that can flexibly identify personnel permissions and control access controllers, effective restrictions on entry of personnel are achieved, which can not only block irrelevant personnel from key areas, but also ensure that relevant personnel can easily enter the equipment control room to perform operations.

[0005] In order to achieve the above object, the present invention adopts the following scheme:

[0006] The substation security system based on 5G communication includes:

[0007] Equipment control room, which is equipped with protective doors, access controller with 5G communication module and image detection equipment;

[0008] An authentication control device, comprising a cloud authentication module with a 5G communication module and a local authentication module, wherein the cloud authentication module is connected to a cloud server, stores permission information and is synchronously loaded into the local authentication module, wherein the permission information includes the door opening permission of the staff and the authorization permission of the management personnel, wherein the authorization permission is used to grant or revoke the door opening permission, and the door opening permission is used to record whether the staff can trigger the access controller and the allowed door opening frequency;

[0009] The local authentication module is loaded with an image recognition program and continuously obtains detection data of the image detection device. The local authentication module switches between online mode and offline mode, wherein:

[0010] Offline mode operation process: When a person enters the door opening detection area, the local authentication module uses the image recognition program to identify and determine whether the person's information has been entered into the system. If it has been entered, the person's door opening authority information is retrieved. If the person has the door opening authority and has not reached the allowed door opening frequency, the access control controller is triggered to open the protective door and record the door opening time;

[0011] The operation process of online mode: Based on the operation process of offline mode, when the information of the detected person is not entered into the system or the allowed door opening frequency has been reached, the image information of the person is sent to the cloud authentication module through the 5G communication module and the manager is notified. The manager views the image information and chooses whether to grant the person temporary door opening permission.

[0012] Preferably, the access controller is provided with an inductive unlocking module and equipped with a corresponding number of inductive cards, and the authentication control device records the card information of each of the inductive cards, and the card information includes the card code, the staff member to whom it belongs, and the usage log information.

[0013] Preferably, the induction card is classified into a general authority card and a dedicated authority card according to the card code, and the induction unlocking module works as follows:

[0014] When an induction card is detected, the card information of the induction card is identified, the type of the induction card is identified according to the card code, and the following operations are selected:

[0015] If the induction card is a dedicated permission card, the image data of the image detection device is obtained to analyze whether the person information recorded in the card information is consistent with the person identified by the image detection. If they are consistent, the access control controller is triggered to open the protective door and the door opening time is recorded in the usage log information. If they are inconsistent, a warning of misuse of the induction card is issued;

[0016] If the induction card is a universal authority card, the image data of the image detection device is obtained and the cardholder information is identified, and then the access control controller is triggered to open the protective door, and the door opening time and cardholder information are recorded in the usage log information.

[0017] Preferably, the access controller is provided with an emergency password unlocking module, the password of the emergency password unlocking module is held by an important person, and when the correct password is entered, the access controller is immediately triggered to open the protective door, and the door opening event is recorded as an emergency event. When the access controller is communicated with the cloud authentication module, the recorded emergency event is sent as an alarm message to the cloud authentication module and the management personnel are notified to review or eliminate the alarm.

[0018] Preferably, the image recognition program of the local authentication module includes a face recognition module and a human posture recognition module, and the face recognition module is enabled to perform face recognition and identify the door opening authority only when the human posture recognition module recognizes that a person is facing the protective door.

[0019] Preferably, the equipment control room is also provided with an alarm controlled by the cloud authentication module. When the information of the detected person is not entered into the system or the allowed door opening frequency has been reached, and the manager chooses not to grant the person temporary door opening authority, the alarm will work until the person is driven out of the detection area. When the alarm is triggered, the person is assigned a blacklist status, and the image information of the person who has not been removed from the blacklist status can no longer trigger the authentication process of the authentication control device.

[0020] Preferably, the door opening detection area is provided with an infrared sensor, and the image detection device enters a sleep state if no new detection target is identified after completing a detection, and the image detection device is awakened only when the infrared sensor senses a human body entering the door opening detection area again.

[0021] The present invention includes at least the following beneficial effects: (1) Through the 5G communication cooperation between the cloud authentication module and the local authentication module, the personnel authority information can be quickly configured in the cloud authentication module and updated to the local authentication module in time, so as to accurately control the entry and exit of the equipment control room; (2) The cloud authentication module can store the original personnel authority information and record the changes of the newly added personnel authority information. When the local authentication module fails and loses data or the data expires, the personnel authority information can be quickly updated to the local authentication module after the maintenance is completed to ensure its normal operation; (3) The local authentication module independently stores the complete personnel authority information after the last update. Even if it is disconnected from the cloud authentication module, the authentication process can be completed independently, ensuring the function of normal control of personnel entry and exit; (4) The local authentication module can record the current unauthorized personnel and hand them over to the management personnel for decision-making. Important temporary staff can also enter the equipment control room normally to perform work with the remote permission of the management personnel without system authority, and the authority management is more flexible; (5) By setting the inductive unlocking module and the emergency password unlocking module, a more flexible control method and better emergency response guarantee can be achieved. DETAILED DESCRIPTION

[0022] The present invention is described in further detail below so that those skilled in the art can implement it according to the description.

[0023] The substation security system based on 5G communication provided by the present invention includes:

[0024] The equipment control room is equipped with a protective door, an access controller with a 5G communication module, and an image detection device. The important equipment control devices of the substation are concentrated in the equipment control room, which is the most important control center of the entire substation. The protective door adopts enhanced processing and its switch status is only directly controlled by the access controller. The image detection equipment is installed directly above or above the side of the protective door. The basic equipment includes at least one high-definition camera, and other auxiliary equipment such as scanning imaging instruments can be optionally equipped. Wireless communication can be carried out between all equipment with 5G communication modules and integrated modules.

[0025] An authentication control device, which includes a cloud authentication module with a 5G communication module and a local authentication module. The cloud authentication module is connected to a cloud server, stores permission information and is synchronously loaded into the local authentication module. The permission information includes the door opening permission of the staff and the authorization permission of the management personnel. The authorization permission is used to grant or revoke the door opening permission. The door opening permission is used to record whether the staff can trigger the access controller and the allowed door opening frequency. The cloud authentication module is connected to the cloud server and can access the cloud server anytime and anywhere through web pages, mobile terminals, etc. to view and maintain permission information, which is also convenient for management personnel to perform remote management. Both the cloud authentication module and the local authentication module have chips for caching and calculating data. In terms of data storage, the cloud authentication module serves as a data backup module for the local authentication module to a certain extent, providing a source of data update and recovery. In the authentication control device, each staff member and manager has an independent personal account. The staff account has only read-only functions such as viewing their own permissions and basic information. The manager account has authorization permissions. In addition to all the functions of the staff account, it also has functions such as managing staff permission information, temporary authorization, and processing alarm information. The manager has the authority to enter and exit the equipment control room by default. The frequency of door opening allowed in the door opening permission is set by the manager. As an example, if the frequency of door opening for a staff member is set to a maximum of 5 times a week and a maximum of 2 times a day, then he can only open the protective door 5 times in total in a week and 2 times a day. Once the number is reached in the corresponding period, he can no longer open the door directly.

[0026] The local authentication module is loaded with an image recognition program and continuously obtains detection data of the image detection device. The local authentication module switches between online mode and offline mode, wherein:

[0027] Offline mode operation process: When a person enters the door opening detection area, the local authentication module uses the image recognition program to identify and determine whether the person's information has been entered into the system. If it has been entered, the person's door opening authority information is retrieved. If the person has the door opening authority and has not reached the allowed door opening frequency, the access control controller is triggered to open the protective door and record the door opening time;

[0028] Online mode operation process: Based on the offline mode operation process, when the detected personnel information is not entered into the system or the permitted door opening frequency has been reached, the image information of the personnel is sent to the cloud authentication module through the 5G communication module and the management personnel are notified. The management personnel will view the image information and choose whether to grant the personnel temporary door opening authority. When new staff or temporary staff need to enter the equipment control room, the protective door can be opened by temporary authorization of the management personnel, and then the management personnel can choose whether to enter the staff information into the authentication control device afterwards, so as to realize flexible authorization management and ensure that the staff can enter the equipment control room normally for operation.

[0029] This substation security system cooperates with 5G communication by setting up a cloud authentication module and a local authentication module. It can quickly configure personnel authority information in the cloud authentication module and update it to the local authentication module in time, so as to accurately control the entry and exit of personnel in the equipment control room; the cloud authentication module can store the original personnel authority information and record the changes of the new personnel authority information. When the local authentication module fails and loses data or the data expires, the personnel authority information can be quickly updated to the local authentication module after maintenance to ensure its normal operation; the local authentication module independently stores the complete personnel authority information after the last update, and the authentication process can be completed independently even if it is disconnected from the cloud authentication module, ensuring the normal control of personnel entry and exit; the local authentication module can record the current unauthorized personnel and hand them over to the management personnel for decision-making. Important temporary staff can also enter the equipment control room normally to perform operations with the remote permission of the management personnel without system authority, and the authority management is more flexible.

[0030] In another technical solution, the access controller is provided with an inductive unlocking module and equipped with a number of corresponding inductive cards, and the authentication control device records the card information of each inductive card, the card information including the card code, the staff member, and the usage log information. The inductive unlocking module is also loaded with an image recognition program.

[0031] The induction card is classified into a general authority card and a dedicated authority card according to the card code. The induction unlocking module works as follows:

[0032] When an induction card is detected, the card information of the induction card is identified, the type of the induction card is identified according to the card code, and the following operations are selected:

[0033] If the induction card is a dedicated permission card, the image data of the image detection device is obtained to analyze whether the person information recorded in the card information is consistent with the person identified by the image detection. If they are consistent, the access control controller is triggered to open the protective door and the door opening time is recorded in the usage log information. If they are inconsistent, a warning of misuse of the induction card is issued;

[0034] If the induction card is a universal authority card, the image data of the image detection device is obtained and the cardholder information is identified, and then the access control controller is triggered to open the protective door, and the door opening time and cardholder information are recorded in the usage log information.

[0035] By using the induction unlocking module and induction card, the protective door can be opened normally when the authentication control device fails. Both the exclusive permission card and the general permission card can record the information of people entering and leaving. Among them, the general permission card can be shared, but it still has a record effect for each user, which is convenient for tracing personnel information and can achieve more flexible control methods.

[0036] In another technical solution, the access controller is provided with an emergency password unlocking module, the password of which is held by an important person. When the correct password is entered, the access controller is immediately triggered to open the protective door, and the door opening event is recorded as an emergency event. When the access controller is connected to the cloud authentication module, the recorded emergency event is sent as an alarm message to the cloud authentication module and the management personnel are notified to check or eliminate the alarm. By setting up an emergency password unlocking module, better emergency response protection can be achieved.

[0037] In another technical solution, the image recognition program of the local authentication module includes a face recognition module and a human posture recognition module. Only when the human posture recognition module recognizes that a person is facing the protective door, the face recognition module is enabled to perform face recognition and identify the door opening authority. Through human posture recognition, the movement trend of the person is judged, and the face recognition and authentication process will not be triggered when the person is just passing by or leaving.

[0038] In another technical solution, the equipment control room is also provided with an alarm controlled by the cloud authentication module. When the information of the detected person is not entered into the system or the allowed frequency of door opening has been reached, and the manager chooses not to grant the person temporary door opening authority, the alarm works until the person is driven out of the detection area. When the alarm is triggered, the person is assigned a blacklist identity. The image information of the person whose blacklist identity has not been removed can no longer trigger the authentication process of the authentication control device. By triggering the alarm to drive away irrelevant personnel and add them to the blacklist, the blacklist is permanent or has a certain period of time, which can effectively prevent irrelevant personnel from continuously triggering the detection process in the detection area and affecting the normal operation of the system.

[0039] In another technical solution, the door opening detection area is provided with an infrared sensor, and the image detection device enters a sleep state if it does not recognize a new detection target after completing a detection, and wakes up the image detection device only when the infrared sensor senses a human body entering the door opening detection area again. The infrared sensor replaces the image detection device to wait for the target, and the image detection device does not need to continue working when no one is approaching, thereby reducing energy consumption.

[0040] The number of devices and processing scales described here are used to simplify the description of the present invention, and the application, modification and variation of the present invention will be obvious to those skilled in the art.

[0041] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
