[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] The biometric identification-based identity and authority management method of the stability control device of the present invention comprises the following steps:

[0038] S1: The power dispatching control center enters the information of all plant-side stabilization control device operation and maintenance personnel through the stabilization control identity authority management module;

[0039] Furthermore, the information of the operation and maintenance personnel of the plant-side stabilization and control device includes but is not limited to name, role, biometric information, etc.

[0040] It is recommended to use a unified input format and limit the length of the name when collecting the name information of the operation and maintenance personnel to ensure that the information can be correctly recognized and used by the system. Avoid spelling errors or input errors that cause information confusion and ensure that the entered name information is accurate.

[0041] The roles of operation and maintenance personnel are divided into three categories, including: super administrator, regular operation and maintenance personnel and temporary operation and maintenance personnel.

[0042] Biometric information includes but is not limited to fingerprint feature information, facial feature information, finger / palm vein feature information, iris feature information, etc.

[0043] The corresponding biometric collector is used to collect the biometric information of the operation and maintenance personnel, and the information is processed, identified, and compared, and the processed information is saved in the corresponding biometric database.

[0044] S2: According to the business characteristics of different plant and station stabilization and control devices, configure the operation and maintenance personnel and operation permissions of different stabilization and control devices, and generate the personnel characteristic permission information associated with the stabilization and control devices in combination with the operation and maintenance personnel information;

[0045] The operating permissions of the stabilization and control device include the device operation and maintenance function permissions and biometric management permissions.

[0046] The device operation and maintenance functions include: device information viewing, operation information viewing, device pressure plate insertion and withdrawal, device software changes, device setting value modifications, device strategy table modifications, and transmission experiment.

[0047] Biometric management functions: turn on / off the biometric module, import biometric information, clear the biometric information database, identity and authority verification records, and biometric verification.

[0048] Different roles of the plant-side stabilization and control device operation and maintenance personnel correspond to different stabilization and control device operation permissions: the super administrator role can log in to the stabilization and control device and operate any function of the stabilization and control device; regular operation and maintenance personnel can log in to the stabilization and control device and perform stabilization and control device functions related to daily business; temporary operation and maintenance personnel can log in to the stabilization and control device and perform stabilization and control device functions related to temporary business.

[0049] The business characteristics of different plant and station stabilization and control devices require the configuration of operation and maintenance personnel and operating permissions for different stabilization and control devices based on the functional requirements of the plant and station operation and maintenance work. The super administrator should be the most trusted person in the plant and station management unit, and the regular operation and maintenance personnel should be the personnel in the plant and station management unit who are responsible for the daily operation and maintenance of the plant and station. Temporary operation and maintenance personnel should be the temporary identity permissions set by the manufacturer of the stabilization and control device due to temporary work such as debugging, regular inspection, troubleshooting, and modification of the device, based on the personnel, work content and time limit specified in the work ticket. Such identity permissions will be automatically eliminated when the time limit specified in the work ticket expires.

[0050] You can manually enter the time range of temporary operation and maintenance personnel to set their working hours, achieve flexible control of device time, and better meet business needs. At the same time, setting the maximum use time of temporary operation and maintenance personnel can limit the length of time they can operate on the equipment, which helps to ensure operational safety and optimize resource allocation. Managers can effectively supervise the work process, thereby improving work efficiency and ensuring safety.

[0051] When the temporary maintenance personnel exceed the set operation time limit, any attempt to operate the stability control device will result in failure, and a prompt will be given that the working time limit has been exceeded. After re-logging into the stability control device, the biometric recognition module will pass the verification, but the page will display the operation time limit range of the maintenance personnel and prompt that the login failed and is not within the operation time range.

[0052] S3: The personnel characteristic authority information is configured to the corresponding stabilization control device through confidential transmission;

[0053] Confidential transmission includes transmitting personnel characteristic authority information to the stabilization and control device through online transmission and offline transmission.

[0054] The online transmission method should adopt a communication method based on asymmetric encryption to transmit feature permission information. The encryption method includes but is not limited to SM2.

[0055] Offline transmission should use mobile encrypted media to store feature permission information, and trusted personnel should carry and load the configuration into the corresponding stabilization and control device.

[0056] In the identity authority management module, you can add, delete, and modify the associated stabilization and control devices. The associated stabilization and control devices involve the device name, plant name, and the device's coding identification. Among them, the device name and substation name can be modified, while the coding identification is the unique identification of the device and cannot be changed. By setting the association between the identity authority management module and the stabilization and control device, you can ensure accurate identification and management of the device, and facilitate necessary adjustments and positioning.

[0057] S4: When operating the stabilization and control device, the identity and authority of the personnel and the operating behavior are verified and recorded.

[0058] Furthermore, when operating the stabilization control device, identity and authority verification is performed on personnel and operating behaviors, including device login identity authentication, non-operation and maintenance personnel identity and authority authentication, non-current operator identity and authority authentication, and operation authority authentication.

[0059] Device login identity authentication: During the device login process, the legitimacy of the operator's identity is verified through the device identity authority authentication module. If an illegal person attempts to log in, the login behavior will be rejected and a prompt "Illegal person, login failed" will be displayed.

[0060] The device has a lock screen function. The operator can choose to log out or log in again at any stage by locking the screen. This operation will assume that the current operator has logged out. If you need to operate the device, you need to re-authenticate the device login.

[0061] Identity authentication for non-current personnel: When operation and maintenance personnel A successfully logs in through biometric recognition, and operation and maintenance personnel B tries to operate the device function at this time, after verification by the device identity authority authentication module, the operation behavior is rejected and the prompt "Not the current logged-in personnel, authorization denied" is displayed.

[0062] Operation authority authentication: When the operation and maintenance personnel successfully log in to the stability control device and try to operate the device across permissions, the operation behavior is rejected and a prompt "Operation failed, no operation authority" is displayed.

[0063] Furthermore, evidence storage means that when there is any operation on the device, the device identity and authority authentication module stores and records the personnel information, operation information and operation time of this operation, and this record can be traced back and viewed through the identity and authority verification record function in the biometric management function.

[0064] The operation and maintenance personnel of the stabilization and control device log in to the stabilization and control device and verify the identity and authority authentication module as follows:

[0065] When the stability control operation and maintenance personnel log in to the device, they first enter the function interface of the stability control device. If they are prompted that they are not logged in when trying to operate, the operation and maintenance personnel return to the login page through the lock screen function, and then verify the identity authority authentication module.

[0066] Authentication through the login device ensures that only authorized maintenance personnel can access and operate the stability control device, and records the user's access and operation records, making it easy to track and audit the operation behavior of maintenance personnel, thereby monitoring the use of the equipment. It improves the security, tracking and management of the stability control equipment, increases traceability, and helps to quickly identify the responsible person and solve the problem.

[0067] Biometric information recognition is performed through the biometric recognition module.

[0068] The biometric information of the operation and maintenance personnel is collected through the identity authorization authentication module, and the corresponding biometric information collector is used to obtain and process the biometric information data, which is then compared with the device biobank information.

[0069] When an illegal person tries to log in, the stability control device will refuse the login and prompt "illegal person, login failed".

[0070] The stability control device displays the identity and authority information of the operation and maintenance personnel, and successfully logs into the stability control device.

[0071] After the legitimate operation and maintenance personnel have been verified by the identity authority authentication module, the stabilization and control device will enter the operation and maintenance personnel identity information display page to display the personnel characteristic authority information of the currently logged-in operation and maintenance personnel.

[0072] The operation and maintenance personnel operate on the device function page to verify the identity and authority authentication module.

[0073] When entering the device function page, the operation and maintenance personnel will perform device identity authority authentication module verification when trying to operate the device function.

[0074] When the verification result shows that the current verification person does not match the current login person, the identity authentication of the stability control device fails and the operation is rejected. At the same time, the device prompts the message "Not the current login person, authorization is rejected."

[0075] When the operation and maintenance personnel lack operation authority, the identity authority authentication fails and the operation behavior is rejected. At the same time, the device prompts the message "Operation failed, no operation authority".

[0076] Operation and maintenance personnel operate device functions according to business needs.
