Technical Field

[0001] This application relates to the field of electrical automation equipment safety technology, and in particular to a method, device, electronic device and storage medium for controlling a password lock on an electrical automation equipment. Background Technology

[0002] With the development of automation technology, electrical automation equipment is widely used in various fields such as industry and agriculture, and is closely related to industrial production.

[0003] Currently, the vast majority of electrical automation equipment still uses traditional mechanical locks for security management. Mechanical locks present significant inconvenience and security risks. In emergencies, if the administrator does not have the key with them, unnecessary property loss may occur; conversely, if the administrator's key is stolen and misused, it could also cause substantial property damage and security risks. Therefore, replacing the mechanical locks on electrical automation equipment with combination locks can improve the equipment's security.

[0004] However, during use, combination locks may still pose security risks due to issues such as going offline, password theft, or the user not having the corresponding unlocking authority. Summary of the Invention

[0008] Based on the first communication state, determine the unlocking strategy of the target combination lock on the target electrical automation equipment;

[0009] Control the target combination lock based on the unlocking strategy.

[0010] In one possible implementation, the method further includes:

[0011] If the first communication state indicates that a communication connection exists, then the unlocking strategy of the target combination lock is determined to be online unlocking;

[0012] If the first communication state is no communication connection, then the unlocking strategy of the target combination lock is determined to be offline unlocking.

[0013] In one possible implementation, the method further includes:

[0014] If the unlocking strategy is offline unlocking, then obtain the second communication status of other electrical automation equipment that has already established a communication connection with the equipment control center;

[0015] Query the pre-stored location coordinates of all electrical automation equipment;

[0016] Based on location coordinate information, other electrical automation devices that have a communication connection in the second communication state and are closest to the target electrical automation device are used as communication relay stations;

[0018] In one possible implementation, the method further includes:

[0019] Establish a communication connection between the communication relay station and the target electrical automation equipment;

[0022] Furthermore, based on the password lock unlocking command sent by the user terminal, the electronic terminal corresponding to the current user is determined, and a first random password is sent to the electronic terminal.

[0023] In one possible implementation, the method further includes:

[0024] The receiver receives a second password sent by the user terminal, which is a combination of the first random verification code and the original password according to a preset rule, and also receives a second random password sent by the user terminal.

[0025] Compare the second random password with the first random password to see if they are the same, and verify the second password;

[0026] If the second random password is the same as the first random password, and the second password is verified, then the target password lock is opened based on the second password, and access control is applied to the current user.

[0027] In one possible implementation, the method further includes:

[0028] If the unlocking strategy is online unlocking, the original password is obtained through the user terminal, which includes an electronic terminal or a combination lock control panel.

[0029] The original password is verified, and the user's operation permissions are determined based on the original password after the verification is successful.

[0030] Based on access permissions, unlock and control the target combination lock.

[0031] In one possible implementation, the method further includes:

[0032] Each user's identity information, along with their original password and access permissions, are pre-stored in a chain on the cloud storage terminal.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] To facilitate understanding of the embodiments of this application, the following will provide further explanation and description with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this application.

[0051] Figure 1 This application provides a flowchart illustrating a method for controlling a combination lock in an electrical automation device, as shown in the embodiments below. Figure 1 As shown, the method specifically includes:

[0052] S11. In response to the password lock opening command sent by the user terminal, obtain the first communication status between the target electrical automation equipment to be unlocked and the equipment control center.

[0053] In this embodiment of the application, when a user (e.g., an equipment administrator) wants to open a target electrical automation device, if the user and the target electrical automation device are on the same site, they can directly access it through the control panel of the password lock on the device, such as... Figure 3 As shown, the "Enter Password" command (password lock opening command) is triggered; or, if the user and the target electrical automation equipment are not in the same location, the password lock opening command can be sent to the equipment control center via an electronic terminal (e.g., mobile phone, computer, etc.).

[0054] Furthermore, in response to the lock opening command sent via the two user terminals mentioned above, the control center sends a random message to the target electrical automation equipment to be unlocked to obtain the first communication status between the target electrical automation equipment and the control center. The first communication status includes whether a communication connection exists or not, i.e., whether the target lock of the target electrical automation equipment is online or offline. If the control center receives a return message from the target electrical automation equipment in response to the random message, it indicates that the first communication status is that a communication connection exists, i.e., the target lock of the target electrical automation equipment is online. If the control center does not receive a return message from the target electrical automation equipment in response to the random message within a preset time period, it indicates that the first communication status is that a communication connection does not exist, i.e., the target lock of the target electrical automation equipment is offline.

[0055] S12. Based on the first communication state, determine the unlocking strategy of the target combination lock on the target electrical automation equipment.

[0056] In this embodiment, different first communication states can be pre-set to correspond to different unlocking strategies for the target combination lock. For example, if the first communication state is that a communication connection exists, the unlocking strategy for the target combination lock is determined to be online unlocking; if the first communication state is that a communication connection does not exist, the unlocking strategy for the target combination lock is determined to be offline unlocking.

[0057] S13. Control the target combination lock based on the unlocking strategy.

[0058] If the unlocking strategy is online unlocking, the target combination lock can be opened according to the online unlocking scheme. If the unlocking strategy is offline unlocking, a series of security verifications, including identity verification and password verification, will be performed on the current user according to the offline unlocking scheme. The target combination lock will be opened only after the security verifications are successful. Specific control methods for the target combination lock are detailed in [link to details]. Figure 2 The corresponding embodiments are described in detail, and will not be elaborated here.

[0059] The combination lock control method for electrical automation equipment provided in this application responds to a combination lock opening command sent by a user terminal, obtains the first communication status between the target electrical automation equipment to be unlocked and the equipment control center; determines the unlocking strategy of the target combination lock on the target electrical automation equipment based on the first communication status; and controls the target combination lock based on the unlocking strategy. Compared with existing electrical automation equipment, which may encounter security risks such as offline operation, password theft, and mismatch between user permissions and identities during combination lock use, this method selectively adopts different online or offline unlocking methods according to the communication status between the electrical automation equipment and the control center, and sets a series of security verification conditions for offline unlocking to ensure the security of the electrical automation equipment.

[0060] Figure 2 This is a flowchart illustrating a method for controlling a password lock in the offline state of electrical automation equipment, as provided in an embodiment of this application. Figure 2 As shown, the method specifically includes:

[0061] S21. If the unlocking strategy is offline unlocking, then obtain the second communication status of other electrical automation devices that have established a communication connection with the equipment control center.

[0062] In this embodiment, the identity information of each user (e.g., device administrator, security officer, user with unlocking authority, etc.) and the corresponding original password and operation permissions (e.g., unlocking permission, password modification permission, etc.) can be pre-stored in a chain on a cloud storage terminal. The blockchain, being immutable, ensures information security by storing each user's identity information and corresponding original password and operation permissions within it, using encryption methods and access control mechanisms. Furthermore, the user's identity information can be determined based on the original password entered by the user; and the user's operation permissions can be determined based on the identity information.

[0063] Furthermore, through the above Figure 1 After determining that the unlocking strategy is offline unlocking, the method described herein sends random messages to other electrical automation devices that have already established a communication connection with the equipment control center to obtain the second communication status of the other electrical automation devices. The second communication status includes whether a communication connection exists or not.

[0064] S22. Query the location coordinate information of all pre-stored electrical automation equipment.

[0065] S23. Based on the location coordinate information, other electrical automation devices that have a communication connection in the second communication state and are closest to the target electrical automation device are used as communication relay stations.

[0066] In this embodiment, the location coordinates of all electrical automation devices corresponding to the control center can be stored in advance on the cloud storage terminal. After obtaining the second communication status of other electrical automation devices, the location coordinates of all electrical automation devices stored on the cloud storage terminal can be queried.

[0067] Other electrical automation devices that have a communication connection in the second communication state and whose location coordinates are closest to the target electrical automation device are used as communication relay stations.

[0068] S24. Establish a communication connection between the communication relay station and the target electrical automation equipment.

[0069] In this embodiment, all electrical automation devices are also connected by communication. After confirming the communication relay station, the device control center can send a communication connection establishment command to the communication relay station to establish a communication connection between the communication relay station and the target electrical automation device. The communication connection establishment command carries a communication connection establishment password. After receiving the communication connection establishment command, the communication relay station sends the communication connection establishment password to the target electrical automation device, so that the target electrical automation device can establish a communication connection with the communication relay station based on the communication connection establishment password.

[0070] S25. Use a random code generator to generate a first random password and a first random verification code.

[0071] The equipment control center is equipped with a random code generator, which can generate random passwords and random verification codes. The random password is used to verify the current user's identity and generate a new password, while the random verification code is used to activate the corresponding indicator light on the PLC controller of the target electrical automation equipment, allowing the current user to recompile a new unlocking password based on the indicator light.

[0072] S26. Through the communication connection between the communication relay station and the target electrical automation equipment, send the first random verification code to the target electrical automation equipment to turn on the corresponding indicator light of the PLC controller set on the target electrical automation equipment.

[0073] In this embodiment, the corresponding indicator light of the PLC controller can be a light box composed of multiple lights, for example, a total of 10 lights, each light corresponding to a number. The number of lights that are lit indicates which number, and the lighting order is consistent with the random verification code. For example, if the random verification code is 4356, then the light representing the number 4 will flash first, then the light representing the number 3 will flash, then the light representing the number 5 will flash, and finally the light representing the number 6 will flash.

[0074] Alternatively, if it's a 4x10 lightbox, each row of lights corresponds to the numbers 1-10, and the lit light indicates which number it represents. For example, if the random verification code is 4356, then the fourth light in the first row will be lit, the third light in the second row will be lit, the fifth light in the third row will be lit, and the sixth light in the fourth row will be lit.

[0075] This allows the current user to clearly know the first random verification code.

[0076] S27. Furthermore, based on the password lock opening command sent by the user terminal, the electronic terminal corresponding to the current user is determined, and a first random password is sent to the electronic terminal.

[0077] In this embodiment, the user sends a password lock unlocking command to the device control center via an electronic terminal (e.g., mobile phone, computer, etc.). This unlocking command may carry terminal device information of the electronic terminal. Based on this information, the device control center sends a first random password generated by a random code generator to the electronic terminal corresponding to the current user. In this case, if an unauthorized user maliciously unlocks the lock, they will not see the first random password because they do not have an electronic terminal, thus mitigating security risks.

[0078] S28. Receive a second password sent by the user terminal, which is a combination of the first random verification code and the original password according to a preset rule, and receive the second random password sent by the user terminal.

[0079] In this embodiment, a new password generation rule can be preset. For example, the first two digits (43) of the first random verification code (4356) can be combined with the original password (8975) and the last two digits (56) of the first random verification code to generate a second password (43897556). Furthermore, after the current user's electronic terminal receives the first random password sent by the device control center, the user re-enters the first random password through the electronic terminal, and the electronic terminal sends the first random password (second random password) entered by the user to the device control center.

[0080] S29. Compare whether the second random password is the same as the first random password, and verify the second password.

[0081] The equipment control center compares the second random password with the first random password to see if they are the same, and verifies whether the second password is formed by combining the first random verification code and the original password according to preset rules.

[0082] S210. If the second random password is the same as the first random password, and the second password is verified, then the target password lock is opened based on the second password and access control is applied to the current user.

[0083] If the second random password is the same as the first random password, and the second password is verified, the target password lock is opened based on the second password, and access control is applied to the current user. Specifically, access control is applied to the current user based on their assigned operation permissions according to their identity information.

[0084] It should be noted that in the above-mentioned method for controlling the password lock in the offline state of electrical automation equipment, if the password or verification code fails to pass verification at any stage, the unlocking process can be terminated and an alarm can be triggered.

[0085] In another embodiment of this application, a method for controlling a combination lock in the online state of electrical automation equipment is also provided, comprising: if the unlocking strategy is online unlocking, obtaining the original password through a user terminal, wherein the user terminal includes an electronic terminal or a combination lock control panel; verifying the original password, and after the original password is verified, determining the current user's operating permissions based on the original password; and unlocking and controlling the target combination lock based on the operating permissions. When the user enters the original password incorrectly a predetermined number of times, the unlocking process can be terminated and an alarm can be triggered. After one incorrect entry of the original password, a facial recognition function can also be added to ensure that the current user is a legitimate user.

[0086] The combination lock control method for electrical automation equipment provided in this application responds to a combination lock opening command sent by a user terminal, obtains the first communication status between the target electrical automation equipment to be unlocked and the equipment control center; determines the unlocking strategy of the target combination lock on the target electrical automation equipment based on the first communication status; and controls the target combination lock based on the unlocking strategy. Compared with existing electrical automation equipment, which may encounter security risks such as offline operation, password theft, and mismatch between user permissions and identities during combination lock use, this method selectively adopts different online or offline unlocking methods according to the communication status between the electrical automation equipment and the control center, and sets a series of security verification conditions for offline unlocking to ensure the security of the electrical automation equipment.
