[0054] The maintenance anti-misoperation management subsystem is used for anti-misoperation locking and permission control of device operation in a maintenance operation process, and sends operation information to the intelligent anti-misoperation host through the communication module.

[0055] In the embodiment, the intelligent anti-misoperation host is a system core control device, and is integrated with a communication module and a control module. Through data interaction and logic processing, unified control of each subsystem is realized. The communication module is responsible for data transmission (such as receiving state information and issuing control instructions) with each subsystem, and supports wired / wireless communication protocols (such as RFID and Bluetooth). The control module performs logic judgment on the collected device state based on preset anti-misoperation rules, and generates operation instructions or alarm information.

[0056] The primary equipment anti-misoperation subsystem is used for circuit breakers, disconnectors and other primary equipment. Through anti-misoperation locks and logic verification, technical support is provided to prevent misoperation, such as preventing misoperation of breaking / closing and closing with a grounding wire.

[0057] The grounding wire management subsystem tracks the whole process state of the grounding wire from leaving the warehouse to returning through intelligent grounding wire cabinets, state collectors and other devices, such as information monitoring of the whole process of the grounding wire in the warehouse, taking, hanging, removing and returning, and real-time interaction of the grounding wire state information with the anti-misoperation system as an anti-misoperation criterion. The grounding wire management subsystem includes a grounding management function module, a grounding wire management device, a grounding wire state collector, a warehouse position locking component, a grounding identity component, an intelligent grounding wire cabinet and other devices.

[0058] The unlocking key management subsystem is used for realizing directional authorization unlocking control and recording operation person, time and place information when the anti-misoperation device is abnormal or needs to be unlocked for operation and maintenance. The unlocking key management system includes an intelligent unlocking host, an intelligent unlocking key and other devices.

[0059] The secondary equipment anti-misoperation subsystem mainly aims at the lack of technical measures for secondary anti-misoperation in a substation, expands the secondary equipment anti-misoperation function on the basis of the primary equipment anti-misoperation, and is used for monitoring the state of hard pressure plates (physical switches) and soft pressure plates (software switches) in real time, and realizing online checking of the state of secondary pressure plate equipment, remote patrol and other functions on the basis of state monitoring. Meanwhile, the secondary anti-misoperation rules are improved, the secondary equipment is included in the switching operation order, the anti-misoperation check of secondary equipment operation and the anti-misoperation check of secondary equipment participating in the primary equipment operation are realized, the anti-misoperation lock of secondary equipment operation is realized on the basis of the anti-misoperation check of secondary equipment, and the random operation of personnel on secondary equipment and the occurrence of the situation of accidental touch and misoperation of secondary equipment are effectively prevented.

[0060] The maintenance anti-misoperation management subsystem mainly aims at the lack of technical measures for anti-misoperation in the maintenance operation process of a substation, expands the maintenance anti-misoperation function on the basis of the anti-misoperation system, such as locking the operation right of the equipment in the maintenance area to prevent the misoperation of non-maintenance personnel. The maintenance anti-misoperation management subsystem includes a maintenance anti-misoperation function module, a maintenance computer key, a maintenance locking accessory and a lock and other equipment. The functions of locking control, electrical secondary equipment control, maintenance isolation equipment operation right control and maintenance operation area equipment anti-misoperation control of a substation are realized.

[0061] Each subsystem monitors the state of equipment (such as the position of primary equipment, the state of grounding wire and pressure plate) in real time, uploads the state information to the intelligent anti-misoperation host through a communication module, the control module checks the state information based on anti-misoperation rules (such as "prohibition of closing with grounding wire"), the intelligent anti-misoperation host issues an operation permission to the subsystem after the check is passed, and the lock or alarm is triggered if the rules are violated.

[0062] Specifically, the intelligent anti-misoperation host as the core of the system is connected with the primary equipment anti-misoperation subsystem, the grounding wire management subsystem, the unlocking key management subsystem, the secondary equipment anti-misoperation subsystem and the maintenance anti-misoperation management subsystem through the communication module, and the control module realizes the acquisition of the state information of each subsystem and the logical control through the communication module. The primary equipment anti-misoperation subsystem controls the operation process through the preset anti-misoperation logic to avoid risks such as misoperation and load operation; the grounding wire management subsystem monitors the state information of the grounding wire in the whole process such as storage, use and connection, and uploads the information to the intelligent anti-misoperation host through the communication module as an important basis for anti-misoperation verification to prevent accidents such as closing with grounding wire; the unlocking key management subsystem implements directional authorization for unlocking operation, only allows unlocking in the specified scene, and returns the operation record to the intelligent anti-misoperation host to eliminate the risk of illegal unlocking; the secondary equipment anti-misoperation subsystem focuses on the state acquisition and anti-misoperation verification of the hard and soft pressure plates, and the state information collected by the subsystem is transmitted to the control module through the communication module to ensure the standardization of the secondary equipment operation; the maintenance anti-misoperation management subsystem locks and controls the device operation during maintenance operation, and synchronously uploads the operation information to the intelligent anti-misoperation host to prevent unauthorized operation or accidental operation of the running device. The data interaction loop is formed between each subsystem and the intelligent anti-misoperation host through the communication module, the control module performs comprehensive logical verification based on the state information of each subsystem, realizes the anti-misoperation control of the whole link of the power system operation, covers the key scenes such as switching, maintenance and secondary operation, and effectively fills the control blind area of the traditional anti-misoperation system.

[0063] In one of the embodiments, the intelligent anti-misoperation host is further connected with:

[0064] A network equipment anti-misoperation subsystem for physical protection of sensitive areas and network equipment;

[0065] A personnel access management subsystem for checking the identity and qualification of personnel and vehicles;

[0066] An instrument management subsystem for monitoring the entry and exit of safety tools and life cycle management.

[0067] In the embodiment, the intelligent anti-misoperation host is further connected with the network equipment anti-misoperation subsystem, the personnel access management subsystem and the instrument management subsystem through the communication module, which expands the coverage of anti-misoperation control and forms a more comprehensive safety protection system.

[0068] The network equipment error prevention subsystem is aimed at sensitive areas (such as communication rooms and battery rooms) and network equipment (such as switches and routers) in the substation, and realizes error prevention management through physical protection means; it includes intelligent door locks (area access control, cabinet locks), isolation locks, network port physical closure devices and other equipment, associates the access permissions of each area with business processes, realizes dynamic authorization, strictly limits personnel access to sensitive areas, and at the same time physically closes and marks the idle USB, LAN and other network ports to meet the requirements of information security management.

[0069] The personnel access management subsystem is used to verify the identity legitimacy and qualification validity of personnel and vehicles entering the station; it includes personnel qualification and vehicle management modules, face recognition devices, ID card readers, personnel access gates, license plate recognition cameras and vehicle access barriers and other equipment, compares the collected personnel ID information, face features and vehicle license plate information with the preset qualification database, and only allows personnel and vehicles that meet the conditions to enter and exit the substation, ensuring that operating personnel have the corresponding operating qualifications and preventing irrelevant personnel from entering by mistake.

[0070] The tool management subsystem focuses on the whole life cycle management of safety tools in the station, realizes warehouse state monitoring and life warning; it includes safety tool management function modules, intelligent detection devices, radio frequency antennas, electronic tags, intelligent safety tool cabinets, face access integrated machines and other equipment, identifies the warehouse state of safety tools by pasting electronic tags on safety tools and using radio frequency antennas and intelligent detection devices, records the number of uses, verification period and other information in combination with intelligent safety tool cabinets, and automatically issues a warning when the safety tools approach the expiration date or the verification is overdue, ensuring the use of qualified safety tools during operation.

[0071] Specifically, the network equipment error prevention subsystem, the personnel access management subsystem and the tool management subsystem all establish data interaction with the intelligent error prevention host through the communication module: the network equipment error prevention subsystem uploads the access state of sensitive areas and the closure state of network ports to the host as auxiliary criteria for personnel operation permissions; the personnel access management subsystem synchronizes the access records of personnel and vehicles to the host, and links with the operation permissions of the maintenance error prevention management subsystem to ensure that "authorized personnel operate in authorized areas"; the tool management subsystem transmits the state information of safety tools to the host and associates with the operation task for verification (such as checking whether the required safety tools are qualified before operation). The three subsystems cooperate with the aforementioned five subsystems, realize whole-chain error prevention from personnel access, equipment operation to tool use through the unified management of the intelligent error prevention host, and further improve the safety protection system of the substation.

[0072] In one of the embodiments, the secondary equipment error prevention subsystem includes:

[0073] The hard pressure plate detection module includes a Hall sensor connected with the hard pressure plate and a vibration detection unit, which are used for monitoring the position change state of a single hard pressure plate.

[0074] The soft pressure plate monitoring module is signal connected with the soft pressure plate monitoring module through the communication module, and is used for acquiring the state information of the position change of the soft pressure plate.

[0075] In the embodiment, the secondary equipment anti-misoperation subsystem realizes the full state monitoring of the secondary equipment (pressure plate type) through the cooperation of the hard pressure plate detection module and the soft pressure plate monitoring module, and provides accurate data support for the anti-misoperation check.

[0076] The hard pressure plate detection module is a state acquisition unit of the hard pressure plate (physical on-off switch), and is composed of a Hall sensor and a vibration detection unit. The Hall sensor outputs a position signal of "on" or "off" in real time by sensing the position change of the metal contact of the hard pressure plate. The vibration detection unit synchronously monitors the vibration amplitude and frequency of the hard pressure plate, and the data of the two are used for distinguishing the position change caused by normal operation and the misoperation caused by external vibration, so as to ensure the accuracy of state acquisition.

[0077] The soft pressure plate monitoring module is associated with the control loop of the soft pressure plate, and monitors the on-off state change of the soft pressure plate by sensing the remote control instruction (such as the on-off instruction issued by the background system). The state information acquired by the soft pressure plate monitoring module is transmitted to the control module of the intelligent anti-misoperation host through the communication module, and forms a complete data chain of the secondary equipment operation with the state of the hard pressure plate.

[0078] Specifically, when the operator performs the on-off operation on the hard pressure plate, the Hall sensor immediately captures the position change, and the vibration detection unit synchronously records the vibration characteristics (such as short-time vibration caused by operation strength) in the operation process, and transmits the data to the subsequent processing unit. For the soft pressure plate, when the background system issues an instruction such as "on #1 line protection soft pressure plate", the soft pressure plate monitoring module captures the instruction in real time and feeds back the current state, so that the control module accurately masters the logical switch state of the secondary equipment. The control module forms a closed loop with the intelligent anti-misoperation host: based on the physical state of the hard pressure plate and the logical state of the soft pressure plate, the control module combines the preset anti-misoperation rule (such as "when a certain protection soft pressure plate is on, the corresponding hard pressure plate must be on at the same time"), and checks the secondary operation, so as to prevent the risk of protection failure caused by misoperation or state mismatch.

[0079] In one of the embodiments, the secondary equipment anti-misoperation subsystem further includes:

[0080] The protection screen cabinet is integrated with several hard panels, a hard panel state collector and a graphic display module, and the graphic display module is used for displaying the on-off state of the hard panel in a graphic manner in real time.

[0081] The control module is signal connected with the hard panel state collector through a communication module, and is used for acquiring state information of the on-off position change of the hard panel; the hard panel state collector is electrically connected with the hard panel detection module, and the hard panel state collector comprises a state collection unit, a logic judgment unit and an audible and light alarm unit.

[0082] The state collection unit is used for receiving the change state data of the on-off position of the hard panel transmitted by the hard panel detection module.

[0083] The logic judgment unit is signal connected with the hard panel detection module, and is used for distinguishing whether the state change of the hard panel is caused by human operation or vibration.

[0084] The audible and light alarm unit is used for alarming when the misoperation is determined.

[0085] In the embodiment, the secondary equipment anti-misoperation subsystem is integrated with the protection screen cabinet and the hard panel state collector, the state processing and visual control of the hard panel are strengthened, and the anti-misoperation reliability of the secondary operation is further improved.

[0086] The protection screen cabinet is used as an installation and operation carrier of the hard panel, and is integrated with several hard panels, a hard panel state collector and a graphic display module; the graphic display module displays the current state of each hard panel in real time through dynamic icons (such as green for on and red for off), so as to facilitate the intuitive checking of the operator and reduce the error of manual inspection.

[0087] The hard panel state collector is used as an intermediate processing unit of the hard panel detection module and the intelligent anti-misoperation host, and the core comprises a state collection unit, a logic judgment unit and an audible and light alarm unit; the state collection unit receives the Hall sensor position signal and vibration detection data transmitted by the hard panel detection module, and performs preliminary filtering and format conversion; the logic judgment unit distinguishes "human operation" and "vibration misoperation" based on a preset algorithm (such as comparing the vibration frequency threshold value: the vibration frequency caused by operation is usually higher than the natural vibration); when the misoperation is determined, the audible and light alarm unit is immediately started (such as emitting a beeping sound and flashing a red warning light), and abnormal information is simultaneously uploaded to the intelligent anti-misoperation host through the communication module.

[0088] Specifically, when the hard pressure plate abnormally deviates due to equipment vibration: the Hall sensor of the hard pressure plate detection module outputs a position change signal, and the vibration detection unit records low-frequency and long-duration vibration data; the state acquisition unit transmits the two types of data to the logic judgment unit, which is determined as "vibration malfunction" through algorithm comparison, and then triggers the sound and light alarm unit to act, and the graphic display module synchronously flashes the icon corresponding to the hard pressure plate; after the control module of the intelligent anti-misoperation host receives the abnormal information, it immediately locks the operation permission of the related primary equipment (such as prohibiting the closing of the circuit breaker corresponding to the loop), until the operation and maintenance personnel confirm the processing. Through the visualization of the protection screen cabinet and the intelligent judgment of the hard pressure plate state acquisition device, the system realizes the whole-process management and control of "state acquisition-logic analysis-abnormal alarm-operation lockout" of the hard pressure plate, effectively solving the problem of "unclear state and difficult to find misoperation" in the operation of traditional secondary equipment.

[0089] In one of the embodiments, the vibration detection unit comprises a vibration detector and a timer electrically connected with the vibration detector.

[0090] In this embodiment, the vibration detection unit realizes accurate capture of the vibration state of the hard pressure plate through the cooperation of the vibration detector and the timer, and provides key data support for the logic judgment unit to distinguish between "manual operation" and "vibration malfunction".

[0091] The vibration detector, as the core sensing component, adopts a piezoelectric or electromagnetic sensor, which can detect the vibration amplitude and frequency of the hard pressure plate caused by external environment (such as equipment operation vibration and personnel touching) in real time, and convert the vibration signal into an electrical signal output; the timer is electrically connected with the vibration detector, and is used to record the duration of vibration (such as the start time, end time and total duration of vibration). The combination of the two data forms a "vibration feature matrix" (amplitude + frequency + duration), which provides multi-dimensional basis for subsequent judgment.

[0092] Specifically, when the hard pressure plate naturally vibrates due to equipment operation, the vibration detector will capture a signal with low amplitude, high frequency and long duration, and the timer will record the vibration duration (such as more than 30 seconds); when the operator manually operates the hard pressure plate, the vibration detector will detect a vibration signal with short duration (such as 1-2 seconds) and high amplitude (caused by the operation force), and the duration recorded by the timer will be significantly different from that of natural vibration. After these data are transmitted to the logic judgment unit of the hard pressure plate state acquisition device, the operation type can be accurately distinguished through a preset threshold (such as vibration duration < 5 seconds and amplitude > threshold to determine "manual operation"), avoiding misjudgment caused by simply relying on position signals, and improving the reliability of hard pressure plate state monitoring.

[0093] In one of the embodiments, the hard pressure plate detection module further comprises:

[0094] An operation indicator lamp circuit is electrically connected with the Hall sensor and the vibration detection unit, respectively.

[0095] The operation indicator lamp circuit comprises at least two color indicator lamps, and the operation indicator lamp circuit is electrically connected with the hard pad state collector.

[0096] In the embodiment, the hard pad detection module is additionally provided with an operation indicator lamp circuit, and the operation state and abnormal condition of the hard pad are intuitively fed back through the state change of the multi-color indicator lamp, thereby assisting the operator to quickly identify the problem.

[0097] The operation indicator lamp circuit is electrically connected with the Hall sensor, the vibration detection unit and the hard pad state collector of the hard pad detection module, and the core comprises at least two color indicator lamps (such as red, yellow and green), and different colors and flashing modes correspond to different states: red generally represents "current operation target" or "operation error", yellow represents "abnormal displacement (such as vibration malfunction)", and green represents "normal state".

[0098] Specifically, when the intelligent anti-misoperation host issues a hard pad operation task, the operation indicator lamp circuit receives the position signal of the Hall sensor, the red indicator lamp of the hard pad is always on, and the operator is prompted that "this is the pad to be operated currently"; after the operation is completed, the Hall sensor detects that the position is in place, the red indicator lamp is turned off, and the green indicator lamp is briefly turned on and then turned off (indicating that the operation is normal). If the operation is wrong (such as operating a non-instruction pad), the logic judgment unit of the hard pad state collector triggers a signal, the red indicator lamp of the hard pad flashes, and the sound and light alarm unit is linked to issue a prompt. When the vibration detection unit detects the displacement of the hard pad in a non-operation state (such as vibration malfunction), the yellow indicator lamp flashes, and abnormal information is uploaded to the intelligent anti-misoperation host at the same time, so that the operation and maintenance personnel can quickly locate the abnormal pad and shorten the checking time. Through the intuitive feedback of the indicator lamp, the system realizes the visual management of "operation guidance-state confirmation-exception warning", and reduces the failure rate of manual operation.

[0099] In one of the embodiments, the hard pad state collector is connected with a computer key through RFID.

[0100] In the embodiment, the hard pad state collector and the computer key establish wireless data interaction through RFID (radio frequency identification) technology, realize the verification of operation permission and the bidirectional transmission of operation information, and strengthen the anti-misoperation management and control of secondary equipment operation.

[0101] The RFID technology realizes non-contact communication between the RFID tag built in the hard platen state collector and the RFID card reader of the computer key through the RFID tag. The RFID tag stores the unique identification information (such as the number and the circuit to which the hard platen belongs) of the hard platen. The computer key pre-stores the operation task information (such as the hard platen number allowed to be operated and the operation sequence) issued by the intelligent anti-misoperation host.

[0102] Specifically, when the operator performs the hard platen operation, the computer key needs to be close to the hard platen state collector first. The computer key reads the RFID tag information and compares it with the pre-stored operation task. If the tag number matches the task (the permission verification is passed), the computer key sends the "operation allowed" signal to the hard platen state collector, and the red indicator light of the operation indicator light circuit is always on to prompt the operation. If the numbers do not match (operation error), the computer key immediately issues a beeping alarm, and the sound and light alarm unit of the hard platen state collector is started synchronously to prohibit the operation. After the operation is completed, the hard platen state collector returns the "operation completed" signal to the computer key through the RFID, and the computer key uploads the result to the intelligent anti-misoperation host to form an operation closed loop of "host-computer key-collector". This RFID interaction mode ensures that the operation is only performed within the authorized range, avoids no-instruction operation or wrong operation, and further improves the process control of the secondary equipment anti-misoperation.

[0103] In one of the embodiments, the intelligent anti-misoperation host is signal-connected with a mobile monitoring terminal. The mobile monitoring terminal is connected with the computer key through a Bluetooth module, and the mobile monitoring terminal is signal-connected with the soft platen monitoring module.

[0104] In this embodiment, the intelligent anti-misoperation host is signal-connected with the mobile monitoring terminal to build a multi-layer data interaction network of "host-terminal-site equipment", and improve the flexibility and real-time performance of the secondary equipment operation.

[0105] The mobile monitoring terminal as an intermediate interaction node has bidirectional communication capability. On the one hand, the mobile monitoring terminal is signal-connected with the intelligent anti-misoperation host to receive the operation task and anti-misoperation rule information issued by the host and feed back the site operation state. On the other hand, the mobile monitoring terminal is wirelessly connected with the computer key through the Bluetooth module to realize the short-distance transmission of the operation task (such as synchronizing the operation ticket information to the computer key). Meanwhile, the mobile monitoring terminal is signal-connected with the soft platen monitoring module to directly obtain the real-time state of the soft platen (such as the remote control instruction execution result) and reduce the data transmission link.

[0106] Specifically, when the secondary equipment operation is performed: the intelligent anti-misoperation host sends operation range, permission and other information to the mobile monitoring terminal, the terminal transmits the encrypted operation task (such as "put in #2 bus protection hard pressure plate") to the computer key through the Bluetooth module, ensuring the safety of task transmission; when the computer key performs the operation, the mobile monitoring terminal synchronously obtains the state of the associated soft pressure plate (such as "#2 bus protection soft pressure plate has been put in") from the soft pressure plate monitoring module, and transmits it back to the intelligent anti-misoperation host in real time, forming a closed loop of "host-terminal-computer key-equipment"; if the soft pressure plate state is abnormal (such as not acting according to the instruction) during the operation, the mobile monitoring terminal will immediately receive the abnormal signal from the soft pressure plate monitoring module, prompting the operator through sound and light, and feeding back to the host to trigger the lock to avoid the expansion of misoperation. The design solves the limitations of traditional wired transmission, facilitates the operator to flexibly check the state and receive tasks on site, and improves the efficiency and safety of secondary equipment operation.

[0107] In one of the embodiments, the intelligent anti-misoperation host is further provided with a pressure plate anti-misoperation logic generation module and an operation task generation module electrically connected with the pressure plate anti-misoperation logic generation module.

[0108] The anti-misoperation logic generation module is electrically connected with the hard pressure plate detection module and the soft pressure plate monitoring module respectively, and the operation task generation module is electrically connected with the hard pressure plate state collector.

[0109] In this embodiment, the intelligent anti-misoperation host realizes "rule automatic generation-task accurate issuance" of secondary equipment operation through the cooperation of the pressure plate anti-misoperation logic generation module and the operation task generation module, and strengthens the pertinence and executability of the anti-misoperation logic.

[0110] The pressure plate anti-misoperation logic generation module, as the rule core, is electrically connected with the hard pressure plate detection module and the soft pressure plate monitoring module, receives the state information of the two types of pressure plates (such as the physical position of the hard pressure plate and the logic state of the soft pressure plate) in real time, and generates special anti-misoperation logic (such as "prohibit operating the corresponding hard pressure plate when the soft pressure plate is not put in") based on the preset power regulations (such as "when a certain protection device is put in, the corresponding hard pressure plate and soft pressure plate must be put in synchronously").

[0111] The operation task generation module is electrically connected with the pressure plate anti-misoperation logic generation module, converts the anti-misoperation logic output by the pressure plate anti-misoperation logic generation module into specific executable operation tasks (such as "step 1: confirm that the #3 line soft pressure plate has been put in; step 2: put in the #3 line hard pressure plate"), and issues them to the hard pressure plate state collector through the communication module, providing clear guidance for on-site operation.

[0112] Specifically, when the hard pressure plate detection module detects that the "#3 line hard pressure plate is misoperated" (position signal is abnormal), and the soft pressure plate monitoring module feeds back that the "#3 line soft pressure plate is not put into", the pressure plate anti-misoperation logic generation module triggers the anti-misoperation logic ("soft pressure plate is not put into, hard pressure plate operation is invalid"), and transmits the logic rule to the operation task generation module; the operation task generation module generates a correction task of "immediately exit the #3 line hard pressure plate, and check the soft pressure plate state" according to this, and issues the correction task to the hard pressure plate state collector, which prompts the operator to execute through the linkage of the sound and light alarm unit, and returns the task execution result to the intelligent anti-misoperation host, so as to ensure that the secondary equipment operation strictly follows the anti-misoperation rule of "hard-soft pressure plate state matching", and avoids the protection misoperation or refusal caused by state conflict.

[0113] Referring to Figure 3 、 Figure 4 The application also relates to an operation method of a comprehensive intelligent anti-misoperation system, which is applied to the comprehensive intelligent anti-misoperation system and specifically comprises the following steps:

[0114] S10, determining an operation range through an intelligent anti-misoperation host to perform regional authorization;

[0115] S20, a control module receiving hard pressure plate state information and soft pressure plate state information sent by a secondary equipment anti-misoperation subsystem in real time;

[0116] S30, generating pressure plate anti-misoperation logic according to the hard pressure plate state information and the soft pressure plate state information, and generating an operation task based on the pressure plate anti-misoperation logic;

[0117] S40, issuing the operation task to an operation terminal;

[0118] S50, identifying a target device through the operation terminal, and executing corresponding operation after verification.

[0119] The operation method of the comprehensive intelligent anti-misoperation system disclosed in the embodiment realizes the whole-process anti-misoperation management and control of the secondary equipment operation through a five-step process based on the system architecture, and the specific steps are as follows:

[0120] S10, regional authorization: the intelligent anti-misoperation host delimits an operation range (such as the secondary equipment region of the #1 main transformer) according to the work type (such as "#1 main transformer maintenance"), and issues authorization instructions to a maintenance anti-misoperation management subsystem and a personnel access management subsystem through a control module, so that only authorized personnel are allowed to operate in the region, and irrelevant personnel are prevented from intervening.

[0121] S20, state collection: the control module receives the state data of the secondary device anti-misoperation subsystem in real time through the communication module: the hard pressure plate detection module uploads the hard pressure plate on-off position (verified by the Hall sensor and the vibration detection unit), the soft pressure plate monitoring module uploads the soft pressure plate remote control instruction execution result, and the complete state image of the secondary device is formed.

[0122] S30, logic and task generation: the control module calls the pressure plate anti-misoperation logic generation module, generates the anti-misoperation logic based on the state information received in S20 (such as "#1 main transformer maintenance, its protection hard pressure plate must be withdrawn"), and generates the specific operation task according to the logic (such as "step 1: withdraw the #1 main transformer differential protection hard pressure plate; step 2: confirm that the #1 main transformer differential protection soft pressure plate has been withdrawn").

[0123] S40, task issuing: the intelligent anti-misoperation host issues the operation task to the operation terminal (such as a computer key or a mobile monitoring terminal) through the communication module, and the task includes an encrypted device identifier, an operation sequence and an anti-misoperation verification rule (such as "must be executed according to step 1→step 2").

[0124] S50, on-site execution and verification: the operator uses the operation terminal (such as a computer key) close to the target device (such as a hard pressure plate state collector), the terminal identifies the device identifier through RFID, and compares it with the device identifier in the task; after verification, the terminal unlocks the operation permission (such as turning on the operation indicator light of the hard pressure plate), allowing the operator to perform the on-off operation; after the operation is completed, the terminal returns the result to the intelligent anti-misoperation host, and the control module checks whether the state meets the expectation, if not, the task is ended, if abnormal, an alarm is triggered and the subsequent operation is locked.

[0125] Specifically, assuming that in the #1 line maintenance operation of a certain 110kV substation:

[0126] S10: the host authorizes the operation permission of "#1 line secondary device area", only the computer key of the maintenance personnel can enter;

[0127] S20: the control module receives the state of "#1 line protection hard pressure plate on-off, soft pressure plate on-off";

[0128] S30: generate the logic "protection pressure plate must be withdrawn during maintenance", and the task is "withdraw #1 line protection hard pressure plate→withdraw soft pressure plate";

[0129] S40: issue the task to the computer key of the maintenance personnel;

[0130] S50: the computer key identifies the #1 line protection hard pressure plate collector, allows operation after verification, and feeds back the state to the host after the operation is completed, the host confirms that the pressure plate has been withdrawn, and the task is closed loop.

[0131] The method ensures the whole process of secondary equipment operation controllable and traceable through the standardized process of "authorization-collection-decision-execution-verification", and effectively reduces the risk of misoperation.
