Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a key box control method, device, system and readable storage medium. Background Art

[0002] At present, some fire doors in unmanned computer rooms are opened and closed by mechanical keys. Mechanical keys rely on manual handover and safekeeping, which are prone to security risks such as loss and theft. In addition, remote computer rooms, such as township / village-level computer rooms, are located in remote areas and have old doors. If the door lock structure is forcibly modified or an intelligent access control system is deployed, high construction costs will be incurred.

[0003] In view of the above situation, the industry generally tends to install a wireless network-based key box to store mechanical keys, so as to achieve low-cost management of keys entering and exiting the computer room, while avoiding the need to modify the computer room door. However, this wireless network-based key box unlocking control method has a significant defect: it is highly dependent on the stability of the wireless network. Once the network is unstable or the signal coverage is incomplete, it may lead to unlocking failure, which in turn affects the daily operation and maintenance efficiency of the computer room. More importantly, in the case of extremely strict requirements for internal network security management in the computer room environment, relying on an external network for unlocking control may bring potential security risks.

[0060] Application Overview

[0061] At present, there are many key box products based on wireless networks in the prior art, but they mainly have the following problems:

[0062] 1. Insufficient communication capability: Currently, key box products based on wireless networks lack intranet control capabilities and cannot be connected to the computer room digital system (such as the power environment monitoring platform);

[0063] 2. Dependence on external networks: The current operation mode of key box products based on wireless networks (i.e. unlocking control) needs to be run on the Internet (external network), but the current operation and management of the computer room is run in the enterprise intranet. According to the communication industry and the company's computer room network security management specifications, the operation and management system of the computer room is not allowed to be interconnected between the internal and external networks, which does not comply with the intranet security management specifications.

[0064] In response to the above technical problems, the present application provides a key box control method, device, system and readable storage medium. By adopting a key box with an integrated RS485 communication bus interface, stable communication between the RTU and the key box is achieved, and remote unlocking instructions sent after encryption by the power environment monitoring platform can be received and responded to without relying on an external network, thereby achieving unlocking without relying on an external network, effectively avoiding unlocking failures and security risks that may be caused by external network dependence, ensuring the stability and security of the computer room door lock control, and at least solving the problem that the existing unlocking control method of the key box based on the wireless network requires external network support to complete unlocking, which is prone to cause unlocking failures or security risks.

[0065] After introducing the basic principles of the present application, various non-limiting embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0066] Embodiment 1:

[0067] This embodiment provides a key box control method, which is applied to a key box, wherein the key box integrates an RS485 communication bus interface, such as Figure 1 As shown, the method includes:

[0068] Step S101: using the RS485 communication bus interface to receive the encrypted remote unlocking instruction sent by the RTU (Remote Terminal Unit) data acquisition unit via the RS485 communication bus, wherein the encrypted remote unlocking instruction is generated by the power environment monitoring platform according to the remote unlocking request after receiving the remote unlocking request triggered by the user based on the front-end interface, and sent to the RTU data acquisition unit via the intranet.

[0069] Specifically, the user triggers the remote unlocking request by single-clicking, double-clicking, long pressing, or touching the preset object in the front-end interface of the power environment monitoring platform. Preferably, the user triggers the remote unlocking request by single-clicking the preset object, wherein the preset object can be any form such as a button, text, or picture. For example, the preset object can be a button, and the title on the button can be: "Remote Unlocking" and so on, to prompt the user to click the button to achieve remote unlocking. The power environment monitoring platform receives the remote unlocking request triggered by the user, and generates an encrypted remote unlocking instruction according to the remote unlocking request, and sends the encrypted remote unlocking instruction to the RTU data acquisition unit through the intranet.

[0070] Specifically, the RTU data acquisition unit receives the encrypted remote unlocking command sent by the power environment monitoring platform through the intranet, and sends the encrypted remote unlocking command to the key box through the RS485 communication bus. The key box uses the RS485 communication bus interface to receive the encrypted remote unlocking command sent by the RTU data acquisition unit through the RS485 communication bus.

[0071] It is worth mentioning that the present invention integrates an RS485 communication bus (preferably Wiegand26 protocol) interface on the key box, so that during the unlocking control process, encrypted remote unlocking instructions can be transmitted through the intranet platform (that is, the power environment monitoring platform), thereby eliminating the need to rely on an external network and ensuring data security.

[0072] Step S102: According to the encrypted remote unlocking instruction, the housing door of the key box is controlled to open.

[0073] It should be noted that the encrypted remote unlocking instruction includes: the user identification of the user, the timestamp of triggering the remote unlocking request, the device code of the key box and the dynamic key.

[0074] In an optional embodiment, controlling the housing door of the key box to open according to the encrypted remote unlocking instruction specifically includes:

[0075] Decrypting the encrypted remote unlocking instruction using a preset decryption key to obtain the user identifier, the timestamp, the device code and the dynamic key;

[0076] Verifying the user identifier, the timestamp, the device code, and the dynamic key;

[0077] In response to the verification result being successful, the housing door of the key box is controlled to open.

[0078] Specifically, the key box uses a preset decryption key to decrypt the encrypted remote unlocking instruction, obtains the user ID of the user, the timestamp that triggers the remote unlocking request, the device code of the key box, and the dynamic key, and verifies the following contents based on the user ID, the timestamp, the device code, and the dynamic key: a. the validity of the timestamp, b. the user authority, and c. the legitimacy of the dynamic key. After the verification is passed, the outer shell door of the key box is controlled to open.

[0079] In an optional embodiment, the key box includes: a smart lock controller and an electromagnetic lock, and the control of opening the housing door of the key box specifically includes:

[0080] The smart lock controller generates a DO (Digital Output) control signal and sends the DO control signal to the electromagnetic lock;

[0081] After receiving the DO control signal, the electromagnetic lock generates magnetic attraction by energizing the coil, driving the lock tongue to retract, so that the housing door of the key box is opened.

[0082] Specifically, the smart lock controller generates a DO control signal and sends the DO control signal to the electromagnetic lock through the drive circuit. After the electromagnetic lock receives the DO control signal sent by the smart lock controller, the electromagnetic lock coil is energized to generate magnetic attraction, driving the lock tongue to retract, and the key box housing door automatically pops open.

[0083] In an optional embodiment, after controlling the opening of the housing door of the key box according to the encrypted remote unlocking instruction, the method further includes:

[0084] The RS485 communication bus interface is used to send a status code indicating successful unlocking to the RTU data acquisition unit, so that the RTU data acquisition unit sends the status code to the power environment monitoring platform through the intranet, and the power environment monitoring platform displays information indicating that the key box status is opened in the front-end interface according to the status code, and pops up a prompt for successful operation.

[0085] Specifically, the key box uses the RS485 communication bus interface to send a status code to the RTU data acquisition unit, where the status code is used to indicate successful unlocking. The RTU data acquisition unit receives the status code sent by the key box using the RS485 communication bus, and sends the status code to the power environment monitoring platform through the intranet. The power environment monitoring platform receives the status code sent by the RTU data acquisition unit through the intranet, and based on the status code, displays information indicating that the key box status is open in the front-end interface, and pops up a prompt that the operation is successful.

[0086] In an optional embodiment, the method further includes:

[0087] Receiving, by using the RS485 communication bus interface, a local unlocking command for instructing to open the key box, which is sent by the RTU data acquisition unit via the RS485 communication bus, wherein the local unlocking command is obtained and sent by the RTU data acquisition unit in response to a password input by a user on site being correct;

[0088] According to the local unlocking command, the housing door of the key box is controlled to open.

[0089] Specifically, in response to the password input by the user on site being correct, the RTU data acquisition unit obtains a local unlocking command for instructing to open the key box corresponding to the password input by the user on site, and sends the local unlocking command to the key box through the RS485 communication bus. The key box uses the RS485 communication bus interface to receive the local unlocking command sent by the RTU data acquisition unit through the RS485 communication bus, and controls the opening of the outer shell door of the key box based on the local unlocking command.

[0090] In a specific embodiment, Figure 2 As shown, the intelligent controlled key box product of the present invention relies on the dynamic environment monitoring system equipment and the intranet network platform. Through the real-time database acquisition module, Wiegand26 protocol port driver module, remote intelligent metropolitan area network VPN (Virtual Private Network) networking module, and on-site intelligent RTU data acquisition module of the platform, it has the network conditions for connecting to the key box near the computer room door. The key box product of the present invention has an integrated RS485 communication bus (Wiegand26 protocol) interface, which is connected to the 485 port of the on-site intelligent RTU data acquisition unit (four-core network cable).

[0091] like Figure 3 As shown, the key box product of the present invention is composed of an embedded smart lock controller, an electromagnetic lock for realizing door opening control, a key box cabinet (box) and a communication interface bus, wherein:

[0092] The embedded smart lock controller integrates a receiving module and a micro-control unit. The receiving module is used to receive the input password data and transmit it to the micro-control unit. After the micro-control unit processes the data, it is transmitted to the computer room digital system (such as the dynamic environment monitoring platform).

[0093] The door opening control electromagnetic lock uses electric current to generate suction, thereby driving the electromagnetic lock silicon steel sheet to open and close.

[0094] The communication interface bus is a channel for transmitting data. The present invention utilizes the RS485 communication bus (Wiegand26 protocol) interface to connect with the 485 port of the on-site intelligent RTU data acquisition unit, and transmits data through the intranet platform to ensure data security.

[0095] Specifically, the key box product of the present invention provides a dual-control implementation method combining remote intranet control unlocking + on-site password input unlocking, wherein the specific operation steps of the key box control method corresponding to the remote intranet control unlocking are:

[0096] Step 1. User login and permission authentication

[0097] Specifically, the operation portal: the staff accesses the power environment monitoring platform (dynamic environment platform) through the enterprise intranet, enters the personal account and verification code (two-factor authentication) to complete the login. Permission verification: the platform automatically matches the list of operable computer rooms according to the account permissions, and displays the key box devices within the authorized scope.

[0098] Step 2. Target key box selection and command issuance

[0099] Specifically, device positioning: In the dynamic environment platform interface, search for the key box to be unlocked by the room number, geographic location or device ID. Instruction generation: After clicking the "remote unlocking" button, the platform calls the encryption module to generate an unlocking instruction containing the following information:

[0100] a. Operator ID (that is, the user's user ID) and timestamp (that is, the timestamp that triggered the remote unlock request)

[0101] b. Target key box device code

[0102] c. One-time dynamic key (encrypted based on SM4 algorithm)

[0103] Step 3. Command transmission and protocol analysis

[0104] Specifically, the intranet transmission path: the encrypted command is transmitted to the RTU data acquisition unit in the target computer room through the enterprise intranet VPN tunnel. Protocol conversion: after receiving the command, the RTU forwards the command to the embedded smart lock controller of the key box through the RS485 communication bus (supporting Wiegand26 protocol).

[0105] Step 4. Command verification and security processing

[0106] Specifically, decryption and verification: The smart lock controller uses the preset decryption key to decrypt the instruction and verify the following:

[0107] a. Timestamp validity (to prevent replay attacks)

[0108] b. Operator authority (matching the dynamic ring platform authorization list)

[0109] c. Legality of dynamic key (compared with the key generated by the platform)

[0110] Exception handling: If the verification fails, the controller records the exception log and feeds back the "unlocking denied" status code to the RTU via the RS485 bus.

[0111] Step 5. Electromagnetic lock drive and control signal output

[0112] Specifically, signal triggering: after verification, the micro-control unit of the smart lock controller generates a DO control signal, which is sent to the electromagnetic lock module through the drive circuit. Electromagnetic lock action: after the electromagnetic lock coil is energized, it generates magnetic attraction, drives the lock tongue to retract, and the key box housing door automatically pops open (mechanical structure linkage).

[0113] Step 6. Status feedback and logging

[0114] Specifically, real-time feedback: After the electromagnetic lock is opened, the smart lock controller sends the "unlocking success" status code to the RTU through the RS485 bus, and the RTU synchronizes the status to the dynamic ring platform. Platform display: The target key box status in the dynamic ring platform interface is updated to "opened", and a prompt for successful operation pops up. Log archive: Complete operation records (including operator, time, device ID, command ciphertext, verification results) are stored in the platform database to support audit tracing.

[0115] It should be noted that this embodiment also includes abnormal scenario processing, network interruption: if the intranet communication is abnormal, the dynamic environment platform prompts "failed to send the command" and triggers the automatic retry mechanism (up to 3 times). Device offline: when the key box controller is offline, the RTU reports the "device does not respond" alarm, and the platform generates a work order to notify the operation and maintenance personnel to check on site.

[0116] It is worth mentioning that Figure 4 As shown, the staff remotely sends a remote control command (i.e., a remote unlocking instruction) in the internal system, and utilizes the localized network management function innovatively realized by the present invention, with the network conditions of the intranet and the key box near the machine room door being connected to each other, the intelligent door opening password controller (i.e., the intelligent lock controller) can receive the remote unlocking information sent by the internal system through the RS485 communication bus (Wiegand26 protocol), and after verifying that the data inside the system is correct, it outputs a DO control signal to the door opening control electromagnetic lock, and the door opening control electromagnetic lock opens the door opening mechanism, and the user can open the key box housing door and take out the spare key hidden inside.

[0117] Specifically, Figure 5 As shown, the specific operation steps of the key box control method corresponding to the on-site password input unlocking are:

[0118] The staff enters the password on site or scans the QR code on the box. After receiving the password input, the intelligent door opening password controller will securely transmit it to the intranet VPN network platform through the fully physically isolated microsystem gateway of the dynamic environment system platform. After the verification and permission of the intranet monitoring platform are correct, it outputs a DO control signal to the door opening control electromagnetic lock. The door opening control electromagnetic lock opens the door opening mechanism, and the user can open the key box outer door and take out the spare key hidden inside.

[0119] It is worth mentioning that the key box product of the present invention is directly connected to the dynamic environment monitoring system based on the RS485 communication bus (supporting Wiegand26 and other protocols) interface and communication capabilities, without the need for external network interconnection. The present invention supports remote intranet commands + on-site password input dual verification to improve security. The present invention is based on a low-cost modified key box (integrated RS485 communication bus interface), and realizes digital management through intranet remote control of the key box without the need to modify the computer room door. The present invention realizes key box command transmission and verification based on the enterprise intranet to ensure data security. The present invention combines remote commands with on-site passwords to adapt to scenarios without external networks. The present invention is based on RS485 bus integration and is directly connected to the computer room equipment through the Wiegand26 protocol, without the need for additional network modification. The present embodiment has fully physically isolated communications to ensure intranet data security and complies with network security specifications in the communications industry.

[0120] The key box control method provided by the embodiment of the present invention is based on a key box integrated with an RS485 communication bus interface. The method first uses the RS485 communication bus interface to receive an encrypted remote unlocking instruction sent by a remote terminal unit RTU data acquisition unit through an RS485 communication bus, wherein the encrypted remote unlocking instruction is generated by a power environment monitoring platform according to the remote unlocking request triggered by a user based on a front-end interface after the power environment monitoring platform receives the remote unlocking request, and sends it to the RTU data acquisition unit through an intranet; then, according to the encrypted remote unlocking instruction, the outer shell door of the key box is controlled to open. The present invention realizes stable communication between the RTU and the key box by adopting a key box integrated with an RS485 communication bus interface. It can receive and respond to the remote unlocking command sent by the power environment monitoring platform after encryption without relying on an external network, thereby realizing unlocking without relying on an external network, effectively avoiding the unlocking failure and security risks that may be caused by external network dependence, ensuring the stability and security of the computer room door lock control, and solving the problem that the existing unlocking control method of the key box based on the wireless network requires external network support to complete the unlocking, which is easy to cause unlocking failure or security risks.

[0121] Embodiment 2:

[0122] This embodiment provides a key box control method, which is applied to a remote terminal unit (RTU) data acquisition unit, such as Figure 6 As shown, the method includes:

[0123] Step S201: Receive the encrypted remote unlocking instruction sent by the power environment monitoring platform through the intranet, wherein the encrypted remote unlocking instruction is sent after the power environment monitoring platform receives the remote unlocking request triggered by the user based on the front-end interface and generates the encrypted remote unlocking instruction according to the remote unlocking request.

[0124] Specifically, when a user triggers a remote unlocking request by single-clicking, double-clicking, long pressing, or touching a preset object in the front-end interface of the power environment monitoring platform, the power environment monitoring platform receives the remote unlocking request triggered by the user, and generates an encrypted remote unlocking instruction based on the remote unlocking request, and sends the encrypted remote unlocking instruction to the RTU data acquisition unit through the intranet. The RTU data acquisition unit receives the encrypted remote unlocking instruction sent by the power environment monitoring platform through the intranet.

[0125] Step S202: sending the encrypted remote unlocking instruction to the key box via the RS485 communication bus, so that the key box controls the opening of the housing door of the key box according to the encrypted remote unlocking instruction, wherein the key box integrates an RS485 communication bus interface.

[0126] Specifically, the encrypted remote unlocking instruction is sent to the key box via the RS485 communication bus. The key box uses the RS485 communication bus interface to receive the encrypted remote unlocking instruction sent by the RTU data acquisition unit via the RS485 communication bus, and controls the shell door of the key box to open based on the encrypted remote unlocking instruction.

[0127] In an optional embodiment, after sending the encrypted remote unlocking instruction to the key box via the RS485 communication bus, the method further includes:
