Description
Technical Field
[0001] This invention belongs to the technical field of centralized control center power distribution system, specifically relating to a microcomputer-based anti-misoperation interlocking system applied to centralized control center power distribution systems. Background Technology
[0002] The microcomputer-based anti-misoperation interlocking system of the power distribution system of the centralized control center refers to the use of computer technology, communication technology, and automatic control technology. Through a preset five-prevention rule library and on-site interlocking system, it comprehensively monitors and makes logical judgments on the operation of electrical equipment in the substations under the jurisdiction of the centralized control center, prevents various misoperation accidents, and ensures the safe operation of the power system.
[0003] Chinese patent application number 201821943959.9 discloses an intelligent integrated anti-misoperation interlocking system for power distribution networks. The system is fixedly connected to the anti-misoperation host via an external measurement interface and incoming line unit within a GSN2 high-voltage live display device. A high-resistance detection circuit detects whether the device is energized, and the detection result is transmitted to a computer key. The data center server within the anti-misoperation host analyzes the detection data, and the analysis result is displayed on a passive live display. The system unlocks when the code on the GSN2 high-voltage live display device matches the code on the wireless coded electromagnetic lock; otherwise, it fails to unlock. The anti-misoperation host can also store operation results for easy retrieval, and a power module provides power to the entire system.
[0004] The aforementioned existing technology has the following problems: the GSN2 high-voltage live display device and the wireless coded electromagnetic lock use a fixed code matching, which is easy to crack and steal by technical means, leading to illegal unlocking.
[0005] Therefore, a microcomputer-based anti-misoperation interlocking system for power distribution systems in centralized control centers is designed to solve the above problems. Summary of the Invention
[0006] To address the problems mentioned in the background section, this invention provides a microcomputer-based anti-misoperation interlocking system for power distribution systems in centralized control centers. This system features randomly generated and unpredictable unlocking passwords that cannot be cracked, stolen, or copied through technical means, thus eliminating the possibility of unauthorized unlocking.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a microcomputer-based anti-misoperation interlocking system applied to a centralized control center power distribution system, comprising: The module is designed to construct a primary independent detection module, a secondary verification detection module, and an unlocking module for the operation equipment of the power distribution system in the centralized control center. The detection module uses a primary independent detection module and a secondary verification detection module to detect the energization status of each operating device in the central control center's power distribution system, and determines the final energization status of each operating device based on the detection results of both. The unlocking request module allows staff to input unlocking requests for the operation equipment of the central control center's power distribution system, triggering the unlocking request. The microcomputer module receives the energization status detection results of each operating device in the power distribution system of the central control center. When it receives an unlocking request from the unlocking module, it searches for the energization status of the operating device requesting the unlocking. If the operating device is energized, the unlocking request is rejected. If the operating device is not energized, an unlocking command is randomly sent to the unlocking module. The unlocking module allows staff to unlock the door by sending an unlocking command.
[0008] Furthermore, the unlocking module of the construction module includes a camera unlocking module, a control module, a storage module, a display module, and a password unlocking module. The camera unlocking module captures an image of the staff's face and an image of the staff's ID before unlocking. The storage module pre-stores the facial information of specific unlocking operators of the central control center's power distribution system. The control module compares the facial images. The display module displays the sent unlocking command. The password unlocking module collects the unlocking password after unlocking.
[0009] Furthermore, the specific detection steps of the detection module include: The primary independent testing module independently tests the energization status of each operating device in the central control center's power distribution system. The secondary verification testing module uses a random binary search method to test the energization status of each operating device in the central control center's power distribution system. The test results of the primary independent testing module and the secondary verification testing module are compared. If they are the same, the result is taken as the final energization status of each operating device in the central control center's power distribution system. If they are different, maintenance personnel are assigned to inspect and repair both the primary independent testing module and the secondary verification testing module.
[0010] Furthermore, the secondary verification detection module of the detection module uses a random binary search method to detect the energization status of each operating device in the centralized control center power distribution system, including the following steps: Based on the detection results of an independent detection module, each operating device in the power distribution system of the centralized control center is divided into two groups. It is then determined whether there are any unpowered operating devices among the divided operating devices. If no unpowered operating devices are found, the detection of that group of operating devices is discarded. If an unpowered operating device is found, it is determined whether that unpowered operating device is located in the divided position. If the unpowered operating device is located in the divided position, its power status is detected again. If the unpowered operating device is not located in the divided position, the division is repeated, and this process is repeated until the end, thus detecting the power status of all operating devices.
[0011] Furthermore, during the maintenance of the independent testing module and the secondary verification testing module, the working steps of the independent testing module and the secondary verification testing module include: Based on the detection results of the primary independent detection module and the secondary verification detection module, identify the operating equipment with discrepancies. Then, check and determine the fault status of the primary independent detection module and the secondary verification detection module. Disconnect the primary independent detection module or the secondary verification detection module with a fault, and perform normal detection through the normal primary independent detection module or the secondary verification detection module to avoid prolonged downtime.
[0012] Furthermore, the specific steps for the unlocking request module to input an unlocking request through the unlocking module include: The control module compares the captured image containing the staff's face with the stored image. If the image exists, an unlocking request is triggered; otherwise, no unlocking request is triggered.
[0013] Furthermore, the specific steps for the microcomputer module to randomly send unlocking commands to the unlocking module include: The microcomputer module receives an image with the staff ID taken by the camera unlocking module before unlocking. It randomly selects any three numbers from the staff ID in the image and randomly combines them. The combination with the current timestamp and the randomly combined numbers is used as the unlocking password, i.e. the unlocking command, and sent to the unlocking module.
[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention includes an unlocking request module, a microcomputer module, and an unlocking module. The unlocking request is initiated by the camera unlocking module, which captures an image of the operator's face before unlocking. The control module compares the captured image of the operator's face with a pre-stored image of a specific unlocking operator's face in the storage module. If a match is found, the unlocking is automatically triggered. The unlocking module captures an image of the operator's ID before unlocking, randomly selects any three numbers from the operator's ID in the image, and randomly combines them. The combination of the current timestamp and the randomly combined numbers is sent as the unlocking password. After the display module displays the password, the password unlocking module checks whether the input unlocking password matches. If they match, the lock is unlocked. Compared with existing technologies, the unlocking password is randomly generated and has uncertainty, making it impossible to crack, steal, or copy through technical means, thus eliminating the possibility of illegal unlocking.
[0015] 2. The present invention sets up a detection module, which includes a primary independent detection module and a secondary verification detection module. This not only improves the accuracy of detection, but also allows the two modules to replace each other in case of failure, reducing downtime. Attached Figure Description

The specific steps of the detection module 2 include: The primary independent testing module independently tests the energization status of each operating device in the central control center's power distribution system. The secondary verification testing module uses a random binary search method to test the energization status of each operating device in the central control center's power distribution system. The test results of the primary independent testing module and the secondary verification testing module are compared. If they are the same, the result is taken as the final energization status of each operating device in the central control center's power distribution system. If they are different, maintenance personnel are assigned to inspect and repair both the primary independent testing module and the secondary verification testing module. The secondary verification and testing module uses a random binary search method to detect the energization status of various operating devices in the central control center's power distribution system. The steps include: Based on the detection results of an independent detection module, each operating device in the power distribution system of the centralized control center is divided into two groups. It is then determined whether there are any unpowered operating devices among the divided operating devices. If there are no unpowered operating devices, the detection of that group of operating devices is discarded. If there are unpowered operating devices, it is determined whether the unpowered operating devices are located in the divided position. If the unpowered operating devices are located in the divided position, the power status of the operating devices is detected again. If the unpowered operating devices are not located in the divided position, the division is repeated again. This process is repeated until the end, and the power status of all operating devices is detected. During the maintenance process of the independent testing module and the secondary verification testing module, the working steps of the independent testing module and the secondary verification testing module include: Based on the detection results of the primary independent detection module and the secondary verification detection module, identify the operating equipment with discrepancies.

Unlock request module 3: When an employee has an unlock request for the operation equipment of the power distribution system in the central control center, the unlock request is triggered by inputting the unlock request through the unlock module. The unlocking module includes a camera unlocking module, a control module, and a storage module. The camera unlocking module captures an image of the operator's face before unlocking and sends it to the control module. The storage module pre-stores the facial information of specific unlocking operators in the central control center's power distribution system. The control module compares the captured image of the operator's face with the image in the storage module. If the image exists, an unlocking request is triggered; otherwise, no unlocking request is triggered. Microcomputer module 4 receives the energization status detection results of each operating device in the power distribution system of the central control center. When it receives an unlocking request from the unlocking module, it searches for the energization status of the operating device requesting the unlocking. If the operating device is energized, the unlocking request is rejected. If the operating device is not energized, an unlocking command is randomly sent to the unlocking module. The unlocking module includes a camera unlocking module, a display module, and a password unlocking module. The camera unlocking module takes an image with the staff ID before unlocking, the display module displays the sent unlocking command, and the password unlocking module collects the unlocking password after unlocking.

Unlocking module 5 allows staff to unlock the door by sending an unlocking command.
