BRIEF DESCRIPTION OF DRAWINGS

[0015] Figure 1 is a simple structure diagram of the system of the application. DETAILED DESCRIPTION

[0016] As shown in Figure 1 , the wireless key online intelligent anti-misoperation locking system comprises an anti-misoperation host 1, a communication adapter 2, a computer key 3 and an anti-misoperation lock 4. The anti-misoperation host 1 runs a power safety management system software and is provided with a graphic operation ticket expert system for simulating and pre-rehearsing and real-time anti-misoperation logic judgment. The anti-misoperation host 1 further comprises a monitoring host 5 for monitoring the operation of the entire wireless key online intelligent anti-misoperation locking system. The communication adapter 2 is connected to the anti-misoperation host 1 and is responsible for offline data exchange and computer key charging. The computer key 3 receives the operation ticket sent by the graphic operation ticket expert system of the anti-misoperation host 1 through wireless communication, executes the unlocking and detection of the anti-misoperation lock 4 and supports voice prompt and black box operation recall. The anti-misoperation lock 4 comprises an electrical coded lock and a mechanical coded lock for forced locking of five-prevention equipment. The wireless key online intelligent anti-misoperation locking system supports online, offline and mixed operation modes, realizes multi-task parallel operation and real-time synchronization of the equipment state.

[0017] The graphic operation ticket expert system is an intelligent decision module embedded in the anti-misoperation host and can be realized by using a logic verification algorithm based on topology analysis. The compliance verification sequence of the operation steps is generated in advance to find potential operation conflicts in the simulation and pre-rehearsal stage. The real-time anti-misoperation logic judgment function dynamically corrects the execution conditions of the operation instructions by continuously receiving the equipment state feedback data. The wireless communication mode can select the 5G communication protocol to ensure high-bandwidth and low-latency data transmission. The multi-task parallel operation is realized through a task queue management mechanism, for example, the tasks of different operation areas are allocated to independent processing threads. The real-time synchronization of the equipment state adopts a heartbeat detection mechanism, for example, the equipment state register is polled once every 500 milliseconds.

[0018] Specifically, the graphic operation ticket expert system of the anti-misoperation host computer generates a virtual operation sequence before operation, and verifies the rationality of the operation logic through topology analysis. When actually executed, the computer key receives dynamically updated operation instructions through the wireless network, and simultaneously returns the lock status information to the anti-misoperation host computer. If the detected device status does not match the expected status, the anti-misoperation logic judgment module immediately terminates the relevant operation steps, and sends an alarm instruction to the computer key. The communication adapter takes over data transmission when the wireless network is interrupted, and maintains the basic anti-misoperation function. When performing the unlocking operation, the computer key verifies the lock code through the radio frequency identification technology, and simultaneously records the operation time stamp and the operator identity information. The electric code lock of the anti-misoperation lock is suitable for devices that need to be remotely controlled, such as circuit breaker operating mechanisms, while the mechanical code lock is suitable for scenes without power supply, such as outdoor disconnectors.

[0019] Compared with the prior art, the traditional system only supports offline single-task sequential operation, while the present scheme realizes dynamic adjustment of the operation process through the online mode. In the prior art, the device status update depends on manual confirmation, while in the present scheme, the information lag is eliminated through the automatic state synchronization mechanism. The traditional computer key only serves as an instruction execution terminal, while the computer key in the present scheme has the functions of state acquisition and logic verification. The existing anti-misoperation lock adopts a single locking mode, while in the present scheme, the appropriate locking device is selected according to the device characteristics, thereby improving the locking reliability.

[0020] Through the above technical scheme, the present application solves the problem that the traditional system cannot respond to the device status change in real time, and avoids the risk of misoperation caused by asynchronous information. The multi-task parallel processing mechanism shortens the waiting time of complex operations, and improves the efficiency of switching operation. The flexible switching between online and offline modes ensures the continuity of system operation, and prevents operation interruption caused by communication failure. The bidirectional interaction mechanism of the device status enhances the accuracy of the anti-misoperation logic judgment, and ensures that the operation steps strictly match the actual status on site.

[0021] The present application also includes a ground wire management module for realizing forced locking and real-time acquisition of a temporary ground wire, which comprises a ground wire controller, an intelligent locking pile, an intelligent ground wire clamp and a state ground wire lock. The ground wire controller manages the forced locking of the ground wire storage location, and the state ground wire lock outputs the ground wire hanging / dismantling state information to the computer key 3. When the ground wire is hung, the computer key reads the intelligent ground wire clamp identity; when the ground wire is dismantled, it is confirmed that the conductor end has been dismantled; the system forcibly locks the ground wire storage location to prevent random use. The process of hanging the ground wire is as follows: the anti-misoperation software of the anti-misoperation host computer 1 issues a ticket, the ground wire controller unlocks the locking pile, takes the ground wire, the computer key 3 reads the ground wire clamp identity, identity confirmation, unlocks the state ground wire lock, and hanging confirmation; the process of dismantling the ground wire is as follows: the conductor end is dismantled, the computer key reads the identity, identity confirmation, the lock is unlocked, and then dismantling confirmation is made.

[0022] Wherein, the ground wire controller is a device for controlling the locking state of the ground wire storage location, which can be implemented by an electronic lock with a logic control unit, and the ground wire storage location is unlocked or locked by receiving the instruction of the anti-misoperation host, so as to ensure that the access permission of the ground wire is controlled. The intelligent locking stake is a locking mechanism installed at the ground wire storage location, which can be implemented by an electromagnetic lock or a mechanical interlocking device, and the physical locking of the ground wire storage location is realized through linkage with the ground wire controller, so as to prevent unauthorized access to the ground wire. The intelligent ground wire clamp is a ground wire connecting component integrated with an identity recognition module, which can be implemented by an RFID tag or a two-dimensional code, and the identity uniqueness of the ground wire is verified through scanning by the computer key, so as to avoid misconnection. The stateful ground wire lock is a locking device that can real-time feedback the connection or disconnection state, which can be implemented by a mechanical lock with a position sensor, and an operation feedback signal is generated by detecting the connection state of the ground wire clamp and the conductor end, so as to ensure the integrity of the operation process. The anti-misoperation software billing is to generate an operation instruction with logical constraints through the power safety management system, which can be implemented by an electronic billing module based on a rule engine, and is used to ensure that the operation steps comply with the five-prevention logic. The ground wire controller unlocks the locking stake, which is to control the opening and closing of the mechanical lock through wireless signals, such as an electromagnetic drive device, which is used for remote management of the physical locking state. The stateful ground wire lock is a smart lock integrated with a position sensor, such as a built-in microswitch, which is used to real-time feedback the ground wire connection state. The identity confirmation is to verify the equipment code through radio frequency identification technology, such as the interaction between the RFID tag and the reader, which is used to prevent misoperation of non-designated equipment.

[0023] Specifically, the ground wire management module implements forced locking on the storage location through the ground wire controller, and only after the authorization of the anti-misoperation host, the intelligent locking stake is unlocked to allow access to the ground wire. When connecting the ground wire, the computer key needs to scan the identity information of the intelligent ground wire clamp, and after verification, the stateful ground wire lock is unlocked to complete the connection operation, at this time the ground wire lock uploads the connection state to the system in real time. When removing the ground wire, the system forcibly requires to disconnect the conductor end first, and then the computer key scans the identity of the ground wire clamp and confirms that the conductor end has been removed, and then the ground wire lock is unlocked to complete the removal operation. The whole process forms a closed-loop control through identity verification and state feedback, ensuring the standardization and state synchronization of the ground wire operation. In the process of connecting the ground wire, the anti-misoperation software generates an operation ticket containing the ground wire position information, which avoids the risk of live connection through system logic verification. After receiving the unlocking instruction, the ground wire controller releases the mechanical constraint of the locking stake, and the operator takes out the ground wire, and the computer key automatically reads the electronic identification code of the ground wire clamp and compares it with the preset information in the operation ticket. When the identity matches, the stateful ground wire lock is unlocked to allow connection, and the connection state is uploaded to the anti-misoperation host in real time. In the removal process, it is forcibly required to disconnect the conductor end first, and the physical constraint of the operation sequence is used to prevent the ground wire from being closed. The computer key verifies the identity of the ground wire again in the removal stage, ensuring that the operation object is consistent with the system record, and avoiding leaving the ground wire not removed.

[0024] Compared with the prior art, the traditional system relies on manual checking of the ground wire state and cannot limit the random use of the ground wire, and there is a risk of misoperation. The scheme realizes physical locking through the ground wire controller and the intelligent locking pile, combines identity recognition and state monitoring technology, and puts the ground wire operation into the anti-misoperation logic closed loop management to eliminate human intervention loopholes. The traditional ground wire operation relies on manual checking of equipment identification and operation sequence, and there is a risk of misconnection and omission. The scheme dynamically binds the operation steps and system instructions through the linkage mechanism of electronic identity verification and mechanical locking to eliminate human judgment errors. The existing system cannot obtain the ground wire state in real time, and the sensor data of the state ground wire lock and the real-time interaction of the anti-misoperation host realize the whole process monitoring of the operation process.

[0025] Through the above technical scheme, the application realizes the forced locking management of the ground wire storage location, prevents unauthorized use, ensures the uniqueness of the ground wire connection object through identity verification, avoids the risk of misconnection, ensures that the conductor end is disconnected before the ground wire is removed through real-time state acquisition and operation sequence forced verification, and prevents live operation accidents. The operation state is synchronized with the system in real time, solving the problem of lack of dynamic monitoring in traditional ground wire management. In addition, the application solves the misconnection problem caused by invisible state in ground wire operation, reduces the misoperation rate to below the system fault tolerance threshold through identity verification and operation sequence forced constraint. At the same time, the standardized process reduces the manual verification link, shortens the ground wire connection and removal operation time by about 40%, and significantly improves the switching operation efficiency. The automatic storage of operation records and the state synchronization function provide complete data chain for accident tracing.

[0026] In the application, the power safety management system software is PSM70 power safety anti-misoperation management system. PSM70 power safety anti-misoperation management system is a standardized software platform verified by the industry, which has built-in pre-simulation algorithm and real-time anti-misoperation judgment rule, and can realize multi-task parallel processing through a graphic operation ticket expert system. Specifically, a modular data architecture design can be adopted to ensure the real-time of device state synchronization and operation instruction transmission. The standardized anti-misoperation logic judgment system is an operation logic verification mechanism based on a unified rule library, which can automatically detect logical errors in operation steps through a built-in conflict recognition algorithm. Specifically, a predefined five-prevention device locking strategy can be used to realize data consistency in mixed operation mode.

[0027] Further, the computer key 3 receives the information of the anti-misoperation host 1 through 5G wireless communication. Through 5G wireless communication, high-speed data transmission is realized through enhanced mobile broadband characteristics, and the real-time of instruction transmission is guaranteed through ultra-reliable low-latency communication characteristics, providing bottom-layer communication support for power equipment state synchronization.

[0028] The five-prevention equipment includes but is not limited to circuit breakers, disconnectors, grounding knife switches, and net door equipment. The circuit breaker is a switching device used to cut off or connect the main circuit in the power system, which can be realized by using a switch locking box or a direct current electrical coding lock to avoid load switching operation by forced locking. The disconnector is a non-current-carrying device used to form an obvious breaking point, which can be realized by using software locking or remote locking to prevent live operation of the isolation breaking point. The grounding knife switch is a mechanical switch used for equipment grounding, which can be realized by using a locking device to ensure that the grounding device cannot be mistakenly closed in a live state. The net door equipment is a protective device for live intervals in a substation, which can be realized by using a mechanical coding lock to prevent personnel from mistakenly entering a live area.

[0029] When the wireless key online intelligent anti-misoperation locking system adopts an online mode, real-time transmission is realized through 5G; when a fault occurs, an offline mode is adopted to exchange data through an adapter. The anti-misoperation lock 4 selects according to different scenes in the following manner: A switch locking box or a direct current electrical coding lock is used for a circuit breaker; Software locking or remote locking is used for a disconnector and a grounding knife switch; A mechanical coding lock is combined with a temporary grounding pile for a temporary grounding point.

[0030] The above scheme can meet the safety requirements of different equipment.

[0031] The operation information recorded by the black box function includes executed items, operation time, and misoperation warning, and the storage time is greater than or equal to 10 years.

[0032] The black box function is a tamper-proof storage module for operation process data, which can be realized by combining an embedded memory with a real-time clock chip, and is used to record key node information in the operation process. The executed item is an identifier of a specific step completed in an operation ticket, which can be realized by using a two-dimensional code scanning or RFID identification technology, and is used to verify whether the operation steps are executed in the predetermined order. The operation time is an accurate time stamp corresponding to each operation step, which can be realized by GPS time service or network time protocol synchronization, and is used to establish the association between the operation time sequence and the device state change. The misoperation warning is an alarm signal triggered when the anti-misoperation logic is violated, which can be realized by combining a preset logic judgment rule with sensor feedback, and is used to capture illegal operation behavior in real time. The storage time is greater than or equal to 10 years, which is the minimum retention period requirement of the data storage medium, and can be realized by using an industrial-grade flash memory chip with a redundant backup mechanism, and is used to meet the statutory time limit requirement of the power industry accident traceability.

[0033] Through the technical scheme, the application realizes complete recording and long-term storage of operation process data, and when an incorrect operation accident occurs, the operation process can be accurately restored by calling the stored data, thereby providing an objective basis for accident cause analysis. Accurate recording of operation time can assist in optimizing the switching operation process and shortening the operation interval time. The immediate recording function of the incorrect operation warning can strengthen the standard awareness of the operator and reduce the incidence of human error.

[0034] Finally, it should be emphasized that the above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
