In an exemplary embodiment, as shown in fig. 1, the application provides a door control 8 management system of a transformer substation, wherein the door control 8 management system comprises a plurality of accommodating parts 2, an electronic lock 4, a door control card 6, a door control 8 and electronic equipment 10, the plurality of accommodating parts 2 are used for accommodating a plurality of equipment of the transformer substation correspondingly, the accommodating parts 2 comprise openable or closable doors, the electronic lock 4 is used for opening or closing the doors of the accommodating parts 2, the door control 8 is arranged on the accommodating parts 2, the door control 8 is connected with the electronic lock 4, the door control 8 comprises a wireless reader, the wireless reader is used for identifying the door control card 6, and the electronic equipment 10 is respectively connected with the wireless reader and the electronic lock 4.

Wherein the receiving part 2 refers to a physical structure or space for receiving or placing substation equipment. In a substation, these receptacles 2 may be various cabinets or rooms, which typically contain openable or closable doors for protecting, isolating or facilitating access to the internal equipment. Such as a mechanism box, ladder stand, plenum, protection cabinet, monitoring cabinet, terminal box, sink control cabinet, power distribution cabinet, control room, etc. These receptacles 2 are isolated from the external environment by doors, ensuring that only authorized personnel can access or operate the equipment therein. The electronic lock 4 is a lock device that controls unlocking and locking electronically. The electronic lock 4 may be operated by means of a password, access card 6, biometric technology or remote control, etc. In the substation access control 8 management system, an electronic lock 4 is mounted on the door of the housing 2 for locking or unlocking the door, thereby controlling access to the internal devices. An advantage of the electronic locks 4 is that they may provide a higher level of security and flexibility, allowing a system administrator to remotely grant or revoke access rights. The access card 6 is a card for authentication and authorization, and contains a unique identifier, such as an electronic tag RFID chip or a magnetic stripe, which can reflect the identity information of the employee. In the substation access control 8 management system, staff or other authorized personnel can carry the access control card 6, and access rights to the specific accommodating part 2 can be obtained after the identity is verified through the wireless reader. The access card 6 may set different access levels and time limits for different users. The access control 8 includes a wireless reader and other associated electronics for processing the authentication information of the access 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 door access 8 management system for processing and managing the data of the whole system. The electronic device 10 may include a central control system to monitor and control all electronic locks 4 and access points 8, record access logs, manage access cards 6 and user rights, and other related security functions. The electronic device 10 may be a dedicated access control 8 control panel, server or computer.

By way of example, an access control 8 management system of a substation as shown in fig. 2 can be built in particular. Firstly, a computer is configured as a server for deploying and managing an access control 8 management system, wherein the server is placed at a position which is easy to build a network and wire and convenient to maintain, and the access control 8 management system is installed on the server for managing all wireless readers, tag information and access control 8 authorities. Then, install wireless reader in the entrance guard 8 positions of transformer substation (such as protection cabinet door, control by converging cabinet door, distribution cabinet door and control cabinet door etc.), wherein, can place wireless reader near entrance guard 8 to the electronic tags on the staff's entrance guard card 6 of reading. All the wireless readers are connected to the server through a network, so that stability and instantaneity of data transmission are ensured, and it is required to be noted that wired or wireless network connection can be used for connection of the wireless readers and the server, and the connection is determined according to specific environments and requirements of the transformer substation. Parameters of each wireless reader are configured in an access control 8 management system on the server, including a reading range (such as 1m, 0.5m and the like), and authority of each electronic tag is set to specify which electronic tags can be matched with which wireless readers, so that places where staff can enter are controlled. In the system, rights are allocated to each employee's electronic tag, and an access control 8 into which the employee can enter is designated, wherein in order to ensure the rationality and uniqueness of the rights allocation of the electronic tag, the rights of the electronic tag can be allocated based on the biological identity information, the job level information and the post information of the substation employee included in the electronic tag, so as to avoid rights confusion and security risks. After the configuration is completed, the test and the debugging of the door control 8 management system are required to be carried out, so that the wireless reader can be ensured to correctly read the tag information, and the door control 8 system can control the opening and closing of the door according to the authority.

After the access control 8 management system is built, transformer substation staff can access and operate different areas of the transformer substation by using the access control card 6 based on the access control 8 management system. For example, when a substation employee needs to enter a high-pressure room for equipment inspection, the substation employee needs to carry the access card 6 to go to the identifiable range of the wireless reader before the high-pressure room access 8. When the wireless reader identifies and acquires the electronic tag on the access card 6, the electronic tag is transmitted to the electronic equipment 10, the electronic equipment 10 can verify the biological identity information, the job level information and the post information of the transformer substation staff reflected by the electronic tag, and under the condition that verification is passed, the transformer substation staff carrying the access card 6 is confirmed to obtain the permission, the electronic lock 4 is controlled to be opened and the door opening operation at this time is recorded, and the staff can directly twist the door handle to enter the high-pressure chamber for equipment detection. After the staff finishes detecting the equipment, leaves the entrance guard 8, closes the door by hand and leaves the identifiable range of the wireless reader, the entrance guard 8 can automatically lock the door because the wireless reader does not identify the entrance guard card 6 and the electronic tag. It should be noted that, when the electronic device 10 performs verification according to the biological identity information, the job level information and the post information of the substation employee reflected by the electronic tag, and if the verification fails, the electronic device 10 controls the electronic lock 4 to be in the closed state.

The entrance guard 8 management system of the transformer substation is compact in design, the wireless reader and the electronic lock 4 are convenient to install on doors of the accommodating parts 2 with different sizes, the necessity of a traditional key is eliminated by using the entrance guard card 6, the management difficulty of a physical key is reduced, the entrance guard card 6 is identified by the system through the wireless reader, the permission is automatically verified, the opening and closing of the electronic lock 4 are controlled, and keyless entry and efficient safety management are realized. Through the access control 8 management system software on the server, an administrator can easily configure and modify parameters and permissions of each wireless reader, and the system supports remote operations, allowing the administrator to quickly respond to permission changing requirements, such as employee position changes or temporary access authorizations. The uniqueness of the electronic tag and the high integration of the system ensure the accuracy and the flexibility of the authority allocation, and avoid the confusion and the security risk of the authorities.

In an exemplary embodiment, the access gateway 8 further comprises a power module. The power module is connected with the wireless reader.

Illustratively, a wireless reader requires a stable power supply to ensure continuous, reliable operation, while the power module is capable of providing a stable current and voltage, avoiding reader malfunction or performance degradation due to power supply fluctuations. And secondly, the power supply module has a power supply management function, can adjust output power according to the requirements of the reader, optimize energy consumption and prolong the service life of the reader.

In one exemplary embodiment, the access control 8 also includes a wireless communication module. The wireless communication module is in wired communication with the wireless reader and the wireless communication module is in wireless communication with the electronic device 10.

By way of example, the wireless communication module refers to an electronic device for implementing wireless communication, such as a WIFI communication module, a 5G communication module, and the like. It may connect a wireless reader in the access control 8 system with an electronic device 10, such as a server or control unit, to facilitate the transmission and processing of data. The wireless communication module is responsible for transmitting the information (such as RFID tag information) of the access card 6 read by the wireless reader to the electronic device 10 for processing. The wireless communication module is connected with the wireless reader through wired communication, so that the possibility of signal interference and transmission errors is reduced, and the stability and reliability of data transmission are ensured. The wireless communication module is connected with the electronic equipment 10 through wireless communication, so that the electronic equipment 10 can remotely receive and process data without a physical connection line, and the flexibility and convenience of system deployment are improved. Through the wireless communication module, an administrator can monitor the status of the door access 8 from a remote location, receive alarm and event reports, and configure and update the system.

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

The alarm module is an electronic device for monitoring and responding to abnormal conditions (such as unauthorized access to the entrance guard 8, long-time non-closed door, etc.), and comprises a sensor, a processor and alarm equipment (such as a buzzer, an indicator light or a short message/telephone notice), and is used for giving an alarm when the abnormal conditions are detected.

Illustratively, the alarm module is capable of detecting abnormal behavior of the door access 8 management system, such as unauthorized access attempts, abnormal door opening or closing behavior, and the like. Upon detection of an anomaly, the alarm module immediately triggers an alarm, notifying the relevant personnel via an audible-visual alarm or other means, so as to take timely action. For example, assume that in a substation access control 8 management system, when an employee attempts to enter a protected area during non-working hours, the alarm module immediately detects this abnormal behaviour. Then, the alarm module can trigger an alarm, and an alarm is sent out through the audible and visual alarm, and alarm information is recorded. If the alarm is set as a remote alarm, the system can also automatically send a short message or telephone notice to the attendant or security manager so that they can respond and take action in time. Secondly, the alarm module can also output an alarm signal to the electronic equipment 10 when an emergency (such as a fire disaster) is detected, so that the electronic equipment 10 controls the electronic lock 4 to be opened, and staff can directly enter to process the emergency when carrying no access card 6 or carrying the access card 6 without authority at the moment, thereby avoiding the situation out of control.

In one exemplary embodiment, the electronic device 10 is disposed at a preset location, which is a location where the electronic device 10 and the plurality of door guards 8 satisfy the shortest wiring distance.

Illustratively, locating the electronic device 10 in a predetermined location may minimize the wiring length, which may not only save cable costs, but may also reduce the amount of installation and maintenance effort. The shorter wiring distance is beneficial to reducing attenuation and interference of signals in the transmission process, so that the stability and reliability of data transmission are improved. The layout and the structure of the whole system are considered in the preset position, so that the arrangement of the components such as the electronic equipment 10, the access control 8 and the wireless reader is more reasonable and orderly, and the overall performance of the system is improved. For example, assume that in the access control 8 management system of a substation, an electronic device 10 (such as a server or a control unit) is provided in a control room of the substation, which is a preset location. This location is located in the central area of the substation, facilitating connection to all access control 8 locations. By placing the electronic device 10 in this position, the shortest wiring distance to all of the door guards 8 can be achieved, thereby improving the performance and reliability of the system. In addition, the position of the control room is convenient for maintenance personnel to monitor and maintain the system, and the stable operation of the system is ensured.

In an exemplary embodiment, the wireless reader is configured to identify the access card 6 within a predetermined distance from the receptacle 2, the predetermined distance being a value within 0.5m-1 m.

Illustratively, a distance range of 0.5m-1m allows the wireless reader to identify when an employee approaches the access control 8, avoiding reading errors due to too close a distance. At the same time, this distance also avoids the problem of inaccurate reading due to too far distance, which may increase signal attenuation, affecting the stability of the reading.

In an exemplary embodiment, the receiving part 2 is provided with heat dissipation holes on at least one side.

Illustratively, the heat sink allows the outside air to exchange with the hot air inside the device, helping to carry away the heat generated by the device, keeping the temperature inside the device within a suitable range. For airtight spaces such as a protection cabinet and a terminal box, through the design of the heat dissipation holes, the heat dissipation efficiency can be improved, the heat accumulation in equipment can be reduced, the temperature of the equipment can be reduced, faults and damages caused by overheating can be reduced, and the overall reliability of the system can be improved.

In one exemplary embodiment, the receptacle 2 comprises at least one of a mechanism box, a ladder stand, a plenum, a protective cabinet, a monitoring cabinet, a terminal box, a sink control cabinet.

It should be noted that the accommodating element 2 may also be other cabinets and indoor spaces of the transformer substation, such as a power distribution cabinet, a control room, etc., which are not illustrated here.

In one exemplary embodiment, access card 6 includes an RFID tag.

The RFID technology allows non-contact data exchange between the access card 6 and the reader, and a user can complete identity verification and authorization without physically contacting the access card 6 with the reader, so that the use convenience and the reliability of the system are improved. The RFID tag can be identified by the reader within a certain distance, and even if the RFID tag is beyond a few meters, the system can accurately judge the identity and the access right of the holder of the access card 6, so that the safety and the monitoring capability of the system are improved. Second, the use of RFID tags allows integration of various 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.

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

Wherein the RFID reader can quickly recognize and read information within the RFID tag, typically in hundreds of milliseconds, much faster than conventional contact cards or password entry, thereby improving the efficiency of work and personnel flow. The RFID reader can remotely read RFID tag information in a non-contact mode, the RFID reader is matched with the entrance guard card 6 comprising the RFID tag, personnel can complete identity verification and unlocking of the entrance guard 8 without directly contacting the entrance guard card 6 with the reader, and user experience and convenience of a system are improved.
