These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0079] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0080] Before introducing the embodiments of the present application, the application background of the embodiments of the present application is first explained:

[0081] With the digital and intelligent transformation of the power industry, various technical means have emerged, providing more optional means for daily safety inspections of various equipment in panel cabinets. Online monitoring of panel cabinet door locks and switch status can effectively reduce the workload of safety inspections of equipment in panel cabinets and improve inspection efficiency. Especially for on-site operations, it can better prevent staff from going to the wrong panel cabinet intervals and mistakenly opening panel cabinet doors, thereby improving the safety of daily operation and maintenance.

[0082] In the prior art, the following three methods are mainly used to control the cabinet lock:

[0083] (1) Relying on manual inspection to manage the cabinets is inefficient, error-prone, labor-intensive, and unable to achieve real-time monitoring and implementation records.

[0084] (2) Based on the manual maintenance of the traditional information management platform, manual regular maintenance records are kept of the panel information such as the panel number, name, and substation to which it belongs, which are used for the setting, viewing, maintenance and query of panel information. However, the traditional information management platform uses a wired network or an unencrypted wireless network to transmit the panel unlocking information.

[0085] In summary, the unlocking information transmission of the existing screen cabinet lock control method is unsafe and the unlocking efficiency is low.

[0086] Therefore, how to improve the unlocking efficiency of the cabinet lock control and the security of unlocking information transmission has become a technical problem that needs to be solved urgently.

[0087] In view of the technical problems existing in the prior art, the inventors of this application have the following ideas. For the problem of low security of unlocking information transmission, the Wireless Local Area Network Authentication and Privacy Infrastructure (WLAN Authentication and Privacy Infrastructure, WAPI) protocol can be used for two-way authentication and encrypted transmission of information data. At the same time, the cabinet central control device sends the encrypted biometric information input by the user to the cabinet lock control device, and then the cabinet lock control device encrypts and transmits the verification result with the permission to open the operation to the cabinet central control device after verification, so that the cabinet central control device controls the electromagnetic lock unit to unlock, realizing the automatic unlocking of the cabinet and solving the problem of low unlocking efficiency of the existing cabinet lock control method. At the same time, the cabinet lock control device can obtain the Radio Frequency Identification (RFID) tag information of the devices in the cabinet, so as to judge the state of the devices in the cabinet.

[0088] Figure 1 The schematic diagram of the architecture of the cabinet lock control provided by the embodiment of this application is as Figure 1 shown. The architecture includes a cabinet lock control device, a cabinet central control device, an electromagnetic lock unit, and an RFID reader.

[0089] In a possible implementation, the cabinet lock control device is arranged outside the cabinet, the cabinet central control device is arranged on the surface of the cabinet, the electromagnetic lock unit is arranged on the surface of the cabinet, and the RFID reader is arranged inside the cabinet.

[0090] Next, the technical solutions of this application will be described in detail through specific embodiments. It should be noted that these specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0091] It is worth noting that the application fields of the cabinet lock control method, system, and electronic device of this application are not limited.

[0092] Among them, the execution subject of this application is an electronic device, which can be specifically a cabinet central control device or a cabinet lock control device.

[0093] Figure 2 The flowchart of the cabinet lock control method provided by the embodiment of this application is Figure 1 as Figure 2 shown. This method is applied to the cabinet central control device and may include the following steps:

[0094] Step 11. In response to the biometric information to be verified input by the user, a connection verification request is sent to the cabinet lock control device via a wireless communication method based on the WAPI protocol.

[0095] Among them, the connection verification request carries the identifier of the cabinet central control device.

[0096] In this step, in response to the biometric information to be verified input by the user, the cabinet central control device sends a connection verification request to the cabinet lock control device via a wireless communication method based on the WAPI protocol to ensure the security during the subsequent transmission of the biometric information to be verified and prevent the biometric information to be verified from being tampered with or leaked during the transmission process.

[0097] Exemplarily, the biometric information to be verified may include fingerprint information, face information, iris information, etc. The connection verification request contains the identifier of the cabinet central control device (such as device ID, unique identifier, etc.). The identifier of the cabinet central control device is used to identify which specific cabinet central control device the user requests for connection verification, ensuring that the subsequent cabinet lock control device can accurately identify and verify the connection verification request of the cabinet central control device corresponding to the biometric information to be verified.

[0098] Among them, after receiving the connection verification request from the cabinet central control device, the cabinet lock control device checks whether the request source is credible and confirms that the request comes from a legitimate device. The cabinet lock control device will send an authentication challenge message to the cabinet central control device. After receiving the authentication challenge message sent by the cabinet lock control device, the cabinet central control device verifies it and generates a corresponding response message, and then sends the response message back to the cabinet lock control device. The cabinet lock control device performs the identity verification of the connection verification request. Through the above two-way identity authentication process, the cabinet central control device and the cabinet lock control device will mutually verify their identities to ensure that both devices are real and credible.

[0099] Step 12. After receiving that the connection verification request is passed, the biometric information to be verified is sent to the cabinet lock control device.

[0100] Among them, the biometric information to be verified is used to enable the cabinet lock control device to determine the verification result of whether the user has the permission to open the electromagnetic lock unit in the cabinet central control device.

[0101] In this step, after receiving the instruction that the connection verification request sent by the cabinet lock control device is passed, the cabinet central control device sends the biometric information to be verified input by the user to the cabinet lock control device, and the cabinet lock control device generates the verification result of whether the user has the permission to open the electromagnetic lock unit in the cabinet central control device.

[0102] Optionally, sending the biometric information to be verified to the cabinet lock control device in Step 12 includes the following implementation:

[0103] Step 1: Encrypt the biometric information to be verified according to the shared key.

[0104] The shared key is jointly determined based on the first key of the cabinet control device and the second key of the cabinet lock control device;

[0105] In this implementation, to ensure that the biometric information to be verified is not stolen or tampered with during transmission, it is necessary to encrypt this transmission data. The shared key jointly determined by the first key of the cabinet control device and the second key of the cabinet lock control device is used to encrypt the biometric information to be verified.

[0106] The cabinet control device and the cabinet lock control device exchange the public key in the first key of the cabinet control device and the public key in the second key of the cabinet lock control device through an open communication channel, and then use their own private keys and the public keys of the other party to generate a shared key. This shared key can be used for encryption and decryption operations of subsequent data transmission. The characteristic of the shared key is that only the cabinet control device and the lock control device can know and use it, and unauthorized external users cannot decrypt it.

[0107] Exemplarily, the first key of the cabinet control device is usually generated and stored in a hardware security module, including a first public key and a first private key, which are respectively used for encryption and decryption of information in the cabinet control device. The second key of the cabinet lock control device is usually generated and stored in a hardware security module, including a second public key and a second private key, which are respectively used for encryption and decryption of information in the cabinet lock control device.

[0108] Step 2: Send the encrypted biometric information to be verified to the cabinet lock control device.

[0109] In this implementation, the encrypted biometric information to be verified is sent to the cabinet lock control device through the WAPI protocol. Since the information has been encrypted, even if the information is intercepted during transmission, unauthorized users cannot decrypt and read the content.

[0110] After receiving the encrypted biometric information to be verified, the cabinet lock control device will decrypt the encrypted information using the previously generated shared key. Only the cabinet lock control device can successfully decrypt the information using this shared key, and other devices cannot decrypt this data, thus ensuring the privacy and security of the transmitted data.

[0111] Step 13: After the received verification result indicates that the user has the permission to open the electromagnetic lock unit in the cabinet control device, control the electromagnetic lock unit to open.

[0112] In this step, after the cabinet control device receives the verification result indicating that the user has the permission to open the electromagnetic lock unit, it controls the electromagnetic lock unit to open.

[0113] Before this step, the cabinet lock control device compares the biometric information to be verified with the user biometric information in the database to generate a corresponding verification result. The specific implementation process will be described in detail in the following Figure 4 corresponding embodiment part.

[0114] Among them, the central control device of the cabinet and the electromagnetic lock unit are both arranged on the outer surface of the cabinet, and the electromagnetic lock unit can also be arranged inside the central control device of the cabinet.

[0115] Optionally, the cabinet lock control method provided by the embodiment of the present application may further include the following implementation:

[0116] Step 1: If it is detected that the electromagnetic lock unit does not open within the first preset duration after receiving the verification result, generate a first prompt message.

[0117] Among them, the first prompt message is used to indicate that the unlocking times out.

[0118] In this implementation, if the central control device of the cabinet detects that the electromagnetic lock unit does not successfully open within the first preset duration after the received verification result indicates that there is an unlocking permission, the central control device of the cabinet will generate a first prompt message, indicating that the electromagnetic lock fails to complete the unlocking operation as expected, and it is necessary to check the status of the electromagnetic lock or re-perform the verification.

[0119] In a possible implementation, the first preset duration can be 1 minute, and the first prompt message can be a voice broadcast. The voice broadcast content can be "Unlocking timeout, please check the status of the electromagnetic lock".

[0120] Step 2: If it is detected that the electromagnetic lock unit does not close within the second preset duration after opening, generate a second prompt message.

[0121] Among them, the second prompt message is used to indicate that the door lock closing is abnormal.

[0122] In this implementation, if the electromagnetic lock unit still does not close within the second preset duration after opening, the system will generate a second prompt message to remind that the door lock closing is abnormal, which indicates that the electromagnetic lock fails to close correctly within the specified time, and there may be a problem that the cabinet door is not fully closed or the electromagnetic lock itself is faulty.

[0123] In a possible implementation, the second preset duration can be 20 minutes, and the second prompt message can be a voice broadcast. The voice broadcast content can be "The door lock closing is abnormal, please ensure that the cabinet door has been correctly closed".

[0124] Step 3: If it is detected that the electromagnetic lock unit is opened, but the verification result indicating that the user has the permission to open the electromagnetic lock unit in the central control device of the cabinet is not obtained, generate a third prompt message.

[0125] Among them, the third prompt message is used to indicate an abnormal unlocking.

[0126] In this implementation, if the electromagnetic lock is successfully opened, but the control device in the cabinet fails to obtain the verification result and cannot confirm whether the user has the unlocking permission, the control device in the cabinet will generate a third prompt message to indicate an abnormal unlocking, reminding the user that there may be a permission verification problem or an abnormal operation, so as to ensure the security and normal operation of the cabinet.

[0127] In a possible implementation, the third prompt message can be a voice broadcast, and the voice broadcast content can be "Abnormal unlocking, unable to confirm the operation permission".

[0128] The cabinet lock control method provided by the embodiments of the present application is applied to the control device in the cabinet. The method first responds to the biometric information to be verified input by the user, and sends a connection verification request to the cabinet lock control device through a wireless communication method based on the WAPI protocol. The connection verification request carries the identifier of the control device in the cabinet. Then, after receiving that the connection verification request is passed, the biometric information to be verified is sent to the cabinet lock control device. The biometric information to be verified is used to enable the cabinet lock control device to determine the verification result of whether the user has the permission to open the electromagnetic lock unit in the control device in the cabinet. Finally, after receiving the verification result indicating that the user has the permission to open the electromagnetic lock unit in the control device in the cabinet, the electromagnetic lock unit is controlled to open. This technical solution verifies the connection between the control device in the cabinet and the cabinet lock control device by sending a connection verification request carrying the identifier of the control device through the WAPI protocol, and then sends the biometric information to be verified to the lock control device to verify whether the user has the permission to operate the electromagnetic lock unit. When the verification result confirms that the user has the opening permission, the control device in the cabinet controls the electromagnetic lock unit to open. By combining the wireless communication of the WAPI protocol and the biometric information verification, the security and unlocking efficiency of the cabinet lock control are improved.

[0129] Based on the above embodiments, Figure 3 is a flowchart of the cabinet lock control method provided by the embodiments of the present application Figure 2 As Figure 3 shown, this method is applied to the control device in the cabinet, and this method may include the following steps:

[0130] Step 21, in response to the device information viewing request sent by the cabinet lock control device through a wireless communication method based on the WAPI protocol, obtain the identification information of at least one device in the control device in the cabinet.

[0131] Among them, for each piece of identification information, the identification information is the ultra-high frequency RFID tag information of the device;

[0132] In this step, the cabinet lock control device sends a device information viewing request through the WAPI protocol to request the relevant device identification information in the cabinet central control device. After receiving this request, the cabinet central control device retrieves the devices in the cabinet using an RFID reader according to the device information viewing request and obtains the identification information of at least one device. The cabinet central control device can quickly and accurately provide the identification information of these devices to the cabinet lock control device to ensure the real-time and high-efficiency transmission of the identification information data.

[0133] In a possible implementation, the cabinet lock control device periodically sends a device information viewing request, which can be once every hour.

[0134] Exemplarily, the identification information of each device is represented by a UHF RFID tag, and the RFID tag contains a unique identifier of the device, which can accurately identify the identity and status of each device.

[0135] In a possible implementation manner, the RFID reader is set inside the cabinet to scan and obtain the UHF RFID tag information on the devices in the cabinet, and then the RFID reader transmits the identification information of each device to the cabinet central control device by means of wireless transmission or wired transmission.

[0136] Step 22: Send the identification information of at least one device to the cabinet lock control device.

[0137] In this step, after obtaining the device identification information, the cabinet central control device sorts out this information and sends the identification information of the device back to the cabinet lock control device through a wireless communication method based on the WAPI protocol.

[0138] Among them, through the wireless communication method based on the WAPI protocol, it is ensured that the identification information is transmitted to the cabinet lock control device in a short time, avoiding communication delays or interruptions during the signal transmission process, so as to ensure that the cabinet lock control device can respond in time, enhancing the signal transmission collaborative working efficiency between the cabinet central control device and the cabinet lock control device, and improving the reliability and intelligent level of the cabinet lock control method.

[0139] The cabinet lock control method provided by the embodiment of the present application is applied to the central control device in the cabinet. This method first responds to the device information viewing request sent by the cabinet lock control device through the wireless communication mode based on the WAPI protocol, obtains the identification information of at least one device in the cabinet central control device. For each piece of identification information, the identification information is the ultra-high frequency RFID tag information of the device, and then sends the identification information of at least one device to the cabinet lock control device. In this technical solution, the cabinet central control device receives the device information viewing request from the cabinet lock control device through the wireless communication based on the WAPI protocol, and after obtaining the identification information of the devices in the cabinet central control device, sends this identification information back to the cabinet lock control device, realizing the remote identification and management of each device in the cabinet, and improving the automation and accuracy of the internal device management of the cabinet.

[0140] Based on the above embodiment, Figure 4 is the flow schematic of the cabinet lock control method provided by the embodiment of the present application Figure 3 , as Figure 4 shown, this method is applied to the cabinet lock control device and may include the following steps:

[0141] Step 31: Obtain the connection verification request sent by the cabinet central control device through the wireless communication mode based on the WAPI protocol.

[0142] Among them, the connection verification request carries the identification of the cabinet central control device, and the connection verification request is triggered by the cabinet central control device based on the biometric information to be verified input by the user;

[0143] In this step, in response to the biometric information to be verified input by the user, the cabinet central control device uses the WAPI protocol to send a connection verification request carrying the identification of the cabinet central control device to the cabinet lock control device. This request contains the identification of the cabinet central control device and is used to identify the identity of the cabinet central control device.

[0144] Exemplarily, the identification of the cabinet central control device can be information such as the device serial number and the device installation address.

[0145] Step 32: Determine the device identification that is consistent with the identification of the cabinet central control device in the device identification library, and determine that the connection verification request passes.

[0146] Among them, at least one allowed device identification is pre-stored in the device identification library;

[0147] In this step, after the cabinet lock control device receives the verification request from the cabinet central control device, it will query the device identification library in the cabinet lock control device to check whether the identifier included in the verification request of the cabinet central control device matches the records in the identification library. If the corresponding identifier is found and it is confirmed that the cabinet central control device is a registered legal device, it indicates that the verification request is passed and the cabinet central control device can continue with subsequent operations.

[0148] Among them, if no identifier matching the identifier of the cabinet central control device is found in the device identification library, or the cabinet central control device is marked as illegal, the cabinet lock control device will reject the connection verification request and the cabinet central control device cannot continue to connect.

[0149] Step 33: Send a connection verification request passed to the cabinet central control device and obtain the biometric information to be verified;

[0150] In this step, after the verification request of the cabinet lock control device is passed, the cabinet lock control device will send a response to the cabinet central control device to confirm that its identity verification is passed, and then obtain the biometric information to be verified of the user.

[0151] Among them, the biometric information to be verified may include fingerprint images, facial recognition data or other biometric information, which is used to further confirm the identity of the initiator of the operation request (i.e., the user).

[0152] Step 34: Determine the verification result of whether the user has the permission to open the electromagnetic lock unit in the cabinet central control device according to the biometric information to be verified;

[0153] In this step, the cabinet lock control device will compare the biometric information to be verified collected by the cabinet central control device to confirm whether the user corresponding to the biometric information to be verified matches the biometric information of a certain legal user stored in the database. If the biometric information matches and the user has the permission to open the electromagnetic lock, the verification result is verification success.

[0154] Among them, if the biometric information does not match or the user's permission does not meet the requirements, the verification result is verification failure, and the cabinet central control device will prevent the electromagnetic lock unit from unlocking.

[0155] Exemplarily, the content of biometric information matching may include the matching of fingerprint textures, the recognition of facial features, etc., and the biometric information matching method may be a biometric comparison algorithm.

[0156] Step 35: Send the verification result to the cabinet central control device, and the verification result indicates that the user has the permission to open the electromagnetic lock unit in the cabinet central control device, so that the cabinet central control device controls the electromagnetic lock unit to open.

[0157] In this step, if the verification is passed, the cabinet lock control device will send a verification result to the cabinet central control device, informing that the user corresponding to the biometric information to be verified has passed the identity verification and has the permission to operate the cabinet lock. After receiving the verification result, the cabinet central control device will trigger the unlocking action of the electromagnetic lock unit by controlling the switching mechanism of the electromagnetic lock unit, thereby enabling the user to open the cabinet.

[0158] Among them, the verification result will include clear permission authorization, allowing the user to perform the operation of opening the electromagnetic lock unit. According to the verification result, it can be ensured that only authorized users can operate the electromagnetic lock unit, preventing unauthorized users from performing illegal operations.

[0159] Optionally, sending the verification result to the cabinet central control device in step 35 can be implemented as follows:

[0160] Step 1: Encrypt the verification result according to the shared key.

[0161] Among them, the shared key is jointly determined based on the first secret key of the cabinet central control device and the second secret key of the cabinet lock control device;

[0162] In this implementation, in order to prevent the verification information from being stolen or tampered with during the transmission process and ensure the security of the transmitted information, the cabinet lock control device will encrypt the verification result using the shared key.

[0163] Exemplarily, the first secret key of the cabinet central control device in the above step is usually generated and stored in the hardware security module, including a public key and a private key, which are respectively used for encrypting and decrypting information. The second secret key of the cabinet lock control device is usually generated and stored in the hardware security module, including a public key and a private key, which are respectively used for encrypting and decrypting information.

[0164] Among them, the shared key here is also the shared key in the first implementation method of sending the biometric information to be verified to the cabinet lock control device in step 12, and is used to encrypt the verification result.

[0165] In a possible implementation method, the encryption method of the shared key can be a standard symmetric encryption algorithm to ensure the integrity and confidentiality of the verification result data.

[0166] Step 2: Send the encrypted verification result to the cabinet central control device.

[0167] In this implementation, the cabinet lock control device will send the encrypted verification result to the cabinet central control device through a wireless communication method based on the WAPI protocol. After receiving the encrypted data, the cabinet central control device decrypts the data using the shared key to obtain the verification result.

[0168] Among them, the central control device in the cabinet executes operations according to the decrypted verification result, such as opening the electromagnetic lock unit.

[0169] The cabinet lock control method provided by the embodiment of the present application is applied to a cabinet lock control device. The method first obtains a connection verification request sent by a central control device in the cabinet obtained through a wireless communication method based on the WAPI protocol. The connection verification request carries the identifier of the central control device in the cabinet. The connection verification request is triggered by the central control device in the cabinet based on the biometric information to be verified input by the user. Then, an identifier consistent with the identifier of the central control device in the cabinet is determined in the device identifier library, and it is determined that the connection verification request passes. At least one allowed connection identifier is pre-stored in the device identifier library. A connection verification request passed is sent to the central control device in the cabinet, and the biometric information to be verified is obtained. According to the biometric information to be verified, a verification result of whether the user has the permission to open the electromagnetic lock unit in the central control device in the cabinet is determined. Finally, the verification result is sent to the central control device in the cabinet. The verification result indicates that the user has the permission to open the electromagnetic lock unit in the central control device in the cabinet, so that the central control device in the cabinet controls the electromagnetic lock unit to open. Through this technical solution, by receiving the connection verification request from the central control device in the cabinet, after the cabinet lock control device confirms that the device identifier in the verification request is valid in the device identifier library, the user biometric information is obtained and verified, it is judged whether the user has the permission to operate the electromagnetic lock unit, and finally the verification result is fed back to the central control device to control the unlocking operation of the electromagnetic lock unit. Through the method of combining biometric information verification and device identifier verification, it is ensured that the user can operate the electromagnetic lock unit only after the permission verification passes, improving the security, accuracy and automation management efficiency of the cabinet lock control operation.

[0170] On the basis of the above embodiment, Figure 5 is the process schematic of the cabinet lock control method provided by the embodiment of the present application Figure 4 as Figure 5 shown. The method is applied to a cabinet lock control device and further includes the following steps:

[0171] Step 41: Send a device information viewing request to the central control device in the cabinet through a wireless communication method based on the WAPI protocol;

[0172] In this step, in order to obtain the detailed information of the devices in the device, the cabinet lock control device sends a device information viewing request to the central control device in the cabinet through the WAPI protocol at a preset time interval, for instructing the central control device in the cabinet to return the information related to the devices.

[0173] Among them, the device is an electronic device arranged in the cabinet, which can be a lock, a sensor, a switch, etc.

[0174] In a possible implementation, the preset time interval can be 1 hour.

[0175] Step 42: Receive the identification information of at least one device in the cabinet central control device.

[0176] Among them, for each piece of identification information, the identification information is the ultra-high frequency RFID tag information of the device.

[0177] In this step, after the cabinet central control device receives the device information viewing request, it will return the identification information of the internal devices in the cabinet obtained by the cabinet central control device according to the request content, which is used to help the cabinet lock control device identify and verify the status and functions of each device.

[0178] Among them, the identification information of the device may include the unique identifier of the device, the status or configuration-related information of the device. The identification information (that is, the ultra-high frequency RFID tag information) is stored in the ultra-high frequency RFID tag, and the RFID reader can be used to obtain the identification information stored in the ultra-high frequency RFID tag.

[0179] In a possible implementation, the RFID reader is set at a position inside the cabinet where all the RFID tags of the devices can be scanned and obtained.

[0180] Optionally, the cabinet lock control method provided by the embodiments of the present application further includes the following implementation:

[0181] Step 1: Obtain at least one of the first prompt information, the second prompt information, and the third prompt information sent by the cabinet central control device through the wireless communication method based on the WAPI protocol;

[0182] In this implementation, the cabinet lock control device obtains at least one of the first prompt information, the second prompt information, or the third prompt information sent by the cabinet central control device through the WAPI protocol. Each type of prompt information has different contents to help users and cabinet administrators understand the working status of the device.

[0183] In a possible implementation, at least one of the first prompt information, the second prompt information, and the third prompt information is displayed on the cabinet central control device.

[0184] Step 2: Forward at least one of the first prompt information, the second prompt information, and the third prompt information to the user terminal;

[0185] Among them, the first prompt information is used to indicate that the unlocking times out, the second prompt information is used to indicate that the door lock is abnormally closed, and the third prompt information is used to indicate that the unlocking is abnormal.

[0186] In this implementation, the cabinet lock control device forwards the prompt information received from the cabinet central control device to the user's terminal device (such as a mobile phone, tablet computer or other terminal). The user terminal will display these prompt information to remind the user of the specific anomalies or events corresponding to the prompt information, so that the user can timely learn about the status of the cabinet.

[0187] The cabinet lock control method provided by the embodiment of the present application is applied to a cabinet lock control device. The method first sends a device information viewing request to the cabinet central control device based on the wireless communication method constructed by the WAPI protocol, and then receives the identification information of at least one device in the cabinet central control device. For each identification information, the identification information is the ultra-high frequency RFID tag information of the device. This technical solution effectively realizes the remote viewing and identification of device information in the cabinet central control device based on the wireless communication method of the WAPI protocol. Using the ultra-high frequency RFID tag information as the device identification can accurately identify the identity of each device, improve the automation degree and accuracy of the internal device management and monitoring of the cabinet. At the same time, this method reduces the risk of manual operation and enhances the security and efficiency of the internal device management of the cabinet.
