Description

Technical Field

[0001] The present application relates to the field of access control technology, and in particular to an access control management system for a substation. Background Art

[0002] Key management is an important but often neglected link in the operation and management of substations. With the expansion of substation scale and technological advancement, the types and quantity of equipment inside substations are increasing, and the corresponding keys are also increasing. The traditional key management method, namely manual registration and allocation, can no longer meet the needs of modern substation management.

[0003] Since each location in the substation, such as the mechanism box door, ladder, high-voltage room door, protection cabinet door, monitoring cabinet door, terminal box door, and control cabinet door, etc., needs to be equipped with corresponding keys, and each employee has different keys according to their rank and position, which leads to great complexity and difficulty in key management. When equipment abnormalities occur and unlocking operations are required, the manual registration method is not only inefficient, but also prone to unclear records, omissions, wrong retrieval, and wrong return. This not only increases the workload, but also poses a safety hazard to key management.

[0004] Therefore, how to effectively manage and use these huge number of keys with different functions has become an urgent problem to be solved in substation management. Utility Model Content

[0005] Based on this, it is necessary to provide a door access management system that facilitates substation management.

[0036] In an exemplary embodiment, Figure 1 As shown, the present application provides a access control 8 management system for a substation, which includes multiple containers 2, electronic locks 4, access control cards 6, access control 8 and electronic devices 10. The multiple containers 2 are used to correspond to multiple devices of the substation, and the containers 2 include doors that can be opened or closed; the electronic locks 4 are used to open or close the doors of the containers 2; the access control 8 is arranged on the containers 2, the access control 8 is connected to the electronic lock 4, and the access control 8 includes a wireless reader, which is used to identify the access control card 6; the electronic device 10 is respectively connected to the wireless reader and the electronic lock 4.

[0037] Among them, the container 2 refers to a physical structure or space for accommodating or placing substation equipment. In the substation, these containers 2 can be various cabinets or rooms, which usually contain doors that can be opened or closed to protect, isolate or facilitate access to the internal equipment. For example, mechanism boxes, ladders, high-voltage rooms, protection cabinets, monitoring cabinets, terminal boxes, control cabinets, distribution cabinets, control rooms, etc. These containers 2 are isolated from the external environment by doors to ensure that only authorized personnel can enter or operate the equipment therein. Electronic locks 4 refer to locks that are electronically controlled to open and close. Electronic locks 4 can usually be operated by passwords, access cards 6, biometric technology or remote control. In the substation access control 8 management system, electronic locks 4 are installed on the doors of the containers 2 to lock or unlock the doors, thereby controlling access to internal equipment. The advantage of electronic locks 4 is that they can provide a higher level of security and flexibility, allowing system administrators to remotely authorize or revoke access rights. Access cards 6 refer to cards used for identity authentication and authorization, containing a unique identifier, such as an electronic tag RFID chip or a magnetic stripe, which can reflect the identity information of employees. In the substation access control 8 management system, employees or other authorized personnel will carry access control cards 6 and obtain access rights to specific containers 2 only after their identities are verified through wireless readers. The access control card 6 can set different access levels and time limits for different users. The access control 8 includes a wireless reader and other related electronic components for processing the authentication information of the access control card 6 and interacting with the electronic lock 4 to control the opening and closing of the door. The electronic device 10 refers to a computer or control unit in the access control 8 management system, which is used to process and manage data for the entire system. The electronic device 10 may include a central control system to monitor and control all electronic locks 4 and access control 8 points, record access logs, manage access control cards 6 and user permissions, and other related security functions. The electronic device 10 may be a dedicated access control 8 control panel, server or computer.

[0038] For example, the following can be constructed specifically: Figure 2The access control 8 management system of the substation shown in the figure. First, configure a computer as a server to deploy and manage the access control 8 management system. The server should be placed in a location that is easy to build a network and connect, and easy to maintain; and install the access control 8 management system on the server to manage all wireless readers, tag information and access control 8 permissions. Then, install wireless readers at different access control 8 locations in the substation (such as protection cabinet doors, control cabinet doors, distribution cabinet doors and monitoring cabinet doors, etc.), where the wireless readers can be placed near the access control 8 to facilitate reading the electronic tags on the employee access control cards 6. Connect all wireless readers to the server through the network to ensure the stability and real-time performance of data transmission. It should be noted that for the connection between the wireless reader and the server, a wired or wireless network connection can be used, depending on the specific environment and needs of the substation. Configure the parameters of each wireless reader in the access control 8 management system on the server, including the reading range (such as 1m, 0.5m, etc.), set the permissions of each electronic tag, and specify which electronic tags can match which wireless readers, so as to control the places that employees can enter. In the system, permissions are assigned to each employee's electronic tag, and the access control 8 that they can enter is specified. In order to ensure the rationality and uniqueness of the electronic tag permission assignment, the electronic tag permissions can be assigned based on the substation employee's biometric identity information, rank information, and position information included in the electronic tag to avoid confusion of permissions and security risks. After the above configuration is completed, the access control 8 management system needs to be tested and debugged to ensure that the wireless reader can correctly read the tag information and the access control 8 system can control the opening and closing of the door according to the permissions.

[0039] After the above-mentioned access control 8 management system is constructed, the substation employees can use the access card 6 to access and operate different areas of the substation based on the access control 8 management system. For example, when a substation employee needs to enter the high-voltage room for equipment inspection, he needs to carry the access card 6 and walk to the recognizable range of the wireless reader in front of the high-voltage room access control 8. When the wireless reader recognizes and obtains the electronic tag on the access card 6, it will transmit it to the electronic device 10. The electronic device 10 will verify the biometric identity information, rank information and position information of the substation employee reflected by the electronic tag, and if the verification is passed, confirm that the substation employee carrying the access card 6 has obtained access rights, control the electronic lock 4 to open and record the door opening operation, and the employee can directly twist the door handle to enter the high-voltage room for equipment inspection. When the employee has finished the equipment inspection, leaves the access control 8, closes the door casually, and leaves the recognizable range of the wireless reader, the access control 8 will automatically lock the door because the wireless reader does not recognize the access card 6 and the electronic tag. It should be noted that when the electronic device 10 performs verification based on the biometric identity information, rank information and position information of the substation employee reflected by the electronic tag, and if the verification fails, the electronic device 10 will control the electronic lock 4 to be in a closed state.

[0040] The access control 8 management system of the above-mentioned substation, the wireless reader and the electronic lock 4 are compactly designed and can be easily installed on the doors of the containers 2 of different sizes. The use of the access control card 6 eliminates the necessity of traditional keys and reduces the difficulty of managing physical keys. The system recognizes the access control card 6 through the wireless reader, automatically verifies the authority and controls the switch of the electronic lock 4, realizing keyless entry and efficient security management. Through the access control 8 management system software on the server, the administrator can easily configure and modify the parameters and permissions of each wireless reader, and the system supports remote operation, allowing the administrator to quickly respond to the need for permission changes, such as employee position changes or temporary access authorization. The uniqueness of the electronic tag and the high integration of the system ensure the accuracy and flexibility of permission allocation, avoiding confusion of permissions and security risks.

[0041] In an exemplary embodiment, the access control system 8 further includes a power module, which is connected to the wireless reader.

[0042] For example, a wireless reader requires a stable power supply to ensure that it works continuously and reliably, and the power module can provide stable current and voltage to avoid reader failure or performance degradation due to power fluctuations. Secondly, the power module has a power management function that can adjust the output power according to the needs of the reader, optimize energy consumption, and extend the service life of the reader.

[0043] In an exemplary embodiment, the access control system 8 further includes a wireless communication module. The wireless communication module is connected to the wireless reader by wired communication, and the wireless communication module is connected to the electronic device 10 by wireless communication.

[0044] Exemplarily, the wireless communication module refers to an electronic device for realizing wireless communication, such as a WIFI communication module, a 5G communication module, etc. It can connect the wireless reader in the access control system 8 with the electronic device 10 (such as a server or a control unit) to facilitate data transmission and processing. The wireless communication module is responsible for transmitting the access card 6 information (such as RFID tag information) read by the wireless reader to the electronic device 10 for processing. The wireless communication module and the wireless reader are connected by wired communication, which reduces the possibility of signal interference and transmission errors and ensures the stability and reliability of data transmission. The wireless communication module and the electronic device 10 are connected by wireless communication so that the electronic device 10 can remotely receive and process data without physical connection, which increases the flexibility and convenience of system deployment. Through the wireless communication module, the administrator can monitor the access control 8 status from a remote location, receive alarms and event reports, and configure and update the system.

[0045] In an exemplary embodiment, the access control management system 8 further includes an alarm module. The alarm module is connected to the electronic device 10.

[0046] Among them, the alarm module refers to an electronic device used to monitor and respond to abnormal situations (such as unauthorized door access, doors that have not been closed for a long time, etc.), including sensors, processors and alarm devices (such as buzzers, indicator lights or SMS / phone notifications), which are used to issue an alarm when an abnormality is detected.

[0047] Exemplarily, the alarm module can detect abnormal behavior of the access control 8 management system, such as unauthorized access attempts, abnormal door opening or closing behavior, etc. Once an abnormality is detected, the alarm module will immediately trigger an alarm and notify relevant personnel through an audible and visual alarm or other means so that timely measures can be taken. For example, assuming that in the access control 8 management system of a substation, when an employee attempts to enter a protected area during non-working hours, the alarm module will immediately detect this abnormal behavior. Subsequently, the alarm module will trigger an alarm, issue a warning through an audible and visual alarm, and record the alarm information at the same time. If the alarm is set to a remote alarm, the system will also automatically send a text message or phone notification to the duty personnel or security management personnel so that they can respond and take measures in time. Secondly, the alarm module can also output an alarm signal to the electronic device 10 when an emergency event (such as a fire) is detected, so that the electronic device 10 controls the electronic lock 4 to open. At this time, when the employee does not carry the access card 6 or the access card 6 carried is not authorized, he can also directly enter to handle the emergency event to avoid the situation getting out of control.

[0048] In an exemplary embodiment, the electronic device 10 is disposed at a preset position, where the preset position is a position where the electronic device 10 and a plurality of access control systems 8 meet the shortest wiring distance.

[0049] Exemplarily, setting the electronic device 10 at a preset position can minimize the wiring length, which can not only save cable costs, but also reduce the workload of installation and maintenance. The shorter wiring distance helps to reduce the attenuation and interference of the signal during transmission, thereby improving the stability and reliability of data transmission. The preset position takes into account the layout and structure of the entire system, so that the arrangement of components such as the electronic device 10, the access control 8 and the wireless reader is more reasonable and orderly, which helps to improve the overall performance of the system. For example, suppose that in the access control 8 management system of the substation, the electronic device 10 (such as a server or a control unit) is set in the control room of the substation, which is the preset position. This position is located in the central area of ​​the substation, which is convenient for connecting to all access control 8 positions. By setting the electronic device 10 at this position, the shortest wiring distance to all access control 8 can be achieved, thereby improving the performance and reliability of the system. In addition, the location of the control room also facilitates maintenance personnel to monitor and maintain the system to ensure the stable operation of the system.

[0050] In an exemplary embodiment, the wireless reader is used to identify the access card 6 within a preset distance from the receiving component 2, and the preset distance is a value within 0.5m-1m.

[0051] For example, the distance range of 0.5m-1m allows the wireless reader to identify the employee when he approaches the access control 8, avoiding reading errors caused by being too close. At the same time, this distance also avoids the problem of inaccurate reading caused by being too far away, because too far a distance may increase signal attenuation and affect the stability of reading.

[0052] In an exemplary embodiment, heat dissipation holes are provided on at least one surface of the accommodation component 2 .

[0053] For example, the heat dissipation holes allow the outside air to exchange with the hot air inside the equipment, which helps to remove the heat generated by the equipment and keep the internal temperature of the equipment within an appropriate range. For confined spaces such as protection cabinets and terminal boxes, the design of heat dissipation holes can improve the heat dissipation efficiency, reduce the heat accumulation inside the equipment, reduce the equipment temperature, reduce the failure and damage caused by overheating, and improve the overall reliability of the system.

[0054] In an exemplary embodiment, the accommodation component 2 includes at least one of the following: a mechanism box, a ladder, a high-voltage room, a protection cabinet, a monitoring cabinet, a terminal box, and a control cabinet.

[0055] It should be noted that the accommodation component 2 may also be other cabinets and indoor spaces of the substation, such as a distribution cabinet, a control room, etc., which will not be explained here by way of example.

[0056] In an exemplary embodiment, the access card 6 includes an RFID tag.

[0057] Among them, RFID technology allows contactless data exchange between the access card 6 and the reader. The user can complete identity authentication and authorization without physically touching the access card 6 to the reader, which improves the convenience of use and the reliability of the system. The RFID tag can be recognized by the reader within a certain distance. Even at a distance of several meters, the system can accurately determine the identity and access rights of the holder of the access card 6, which increases the security and monitoring capabilities of the system. Secondly, the use of RFID tags can integrate multiple security features, such as encryption, unique identification codes, etc., which makes it very difficult to forge or copy the access card 6, thereby enhancing the security of the system.

[0058] In one exemplary embodiment, the wireless reader is an RFID reader.

[0059] Among them, the RFID reader can quickly identify and read the information in the RFID tag, usually within a few hundred milliseconds, which is much faster than the traditional contact card or password typing method, thereby improving work efficiency and the efficiency of personnel flow. The RFID reader can read the RFID tag information contactlessly at a long distance. When the RFID reader is used in conjunction with the access card 6 including the RFID tag, employees can complete identity authentication and door unlocking 8 without directly contacting the access card 6 with the reader, which improves the user experience and the convenience of the system.
