Through the steps, the equipment locking subsystem can monitor the working state of the substation equipment, and lock and unlock the equipment according to the instruction information of the background monitoring center. Thus, unauthorized personnel can be prevented from operating the equipment, and the safety and the integrity of the equipment are protected.

Specifically, the device monitoring module is internally provided with a unique identification code, the background monitoring center pre-stores the unique identification codes of all the device monitoring modules and the position information data of the monitored substation devices, the background monitoring center identifies the device locking subsystem through the unique identification codes and determines the position information of the monitored substation devices,

The unique identification code is a 64-bit code in practical application, and is matched through a background monitoring center, so that when a certain transformer substation equipment is abnormal, the unique identification code can be accurately positioned, and a worker can make corresponding measures in time.

The device monitoring module is internally provided with unique identification codes, and the background monitoring center pre-stores the unique identification codes of all the device monitoring modules and the position information data of the monitored substation devices, so that the identification of the device locking subsystem and the determination of the position information of the corresponding substation devices can be realized.

The specific implementation mode is as follows:

the equipment monitoring module is internally provided with a unique identification code: each equipment monitoring module is provided with a unique identification code for distinguishing different equipment monitoring modules. This code may be a unique string or number of 64 bits in length to ensure uniqueness.

The background monitoring center stores coding and position information data: the background monitoring center pre-stores unique identification codes of all equipment monitoring modules and position information data of monitored substation equipment. These data may be stored in a background database for subsequent identification and localization.

And the background monitoring center matches the received identification codes according to the pre-stored data and determines the position information of the monitored substation equipment.

The access terminal is an important component in the monitoring system and is used for uploading reservation identity information data, maintenance substation equipment number data and access time interval data to the background monitoring center.

The specific implementation mode is as follows:

uploading function of the access terminal: the access terminal can be intelligent electronic equipment such as a smart phone or a fixed terminal, and the access terminal can upload reservation identity information data, maintenance substation equipment number data needing to be operated and access time interval data to the background monitoring center. Such data may be uploaded by means of an application or web page, etc.

Reservation operation of the entrant: in practical application, an entering person needs to initiate an entering reservation of a relevant transformer substation on an entering person terminal. The entrant fills in the identity information of the reservation, selects the number of the maintenance substation equipment needing to be operated and enters the time interval. The system can verify and match preset information content, ensure that only the entrants with specified identities are in a specified time interval, and only specified maintenance substation equipment can be operated.

Only if the verification is passed, the background monitoring center sends feedback information to the terminal of the entering person, and the entering person is allowed to enter the transformer substation in a specified time interval.

Through the steps, the terminal of the entering person realizes the functions of uploading reservation identity information data, maintaining substation equipment number data and entering time interval data to the background monitoring center. In this way, the system can accurately control the identity verification and equipment locking of the entrant, ensure that only the appointed identity entrant in the reserved time interval can pass the verification and release the locking of the corresponding equipment.

The principle of the mode is that the verification and the matching of reservation identity information and equipment numbers are realized through the information interaction between the terminal of the entering person and a background monitoring center, so that only the entering person with legal identity can enter the transformer substation and the locking of corresponding equipment is released. The method improves the accuracy of the identity of the entrant and the control capability of the system on the equipment, thereby ensuring the safe operation of the transformer substation and the protection of the equipment.

Specifically, the background monitoring center includes:

the memory is used for storing unique identification codes of all equipment locking subsystems in the transformer substation;

the data processing module is used for sending feedback information to the entrance guard verification subsystem according to the data information uploaded by the entrance terminal by the main control module; transmitting unlocking information to the equipment locking subsystem; the device locking subsystem is used for identifying the device locking subsystem and judging whether the device monitoring data are abnormal or not;

The data processing module processes and stores the uploaded information, the comparison processing of the uploaded data is realized through the data processing module, and the traditional manual verification is replaced by adopting a system automatic verification mode, so that the manpower resource requirement is reduced.

The background monitoring center is a core component of the substation unmanned guard monitoring system and comprises a background wireless communication module, a memory, a data processing module and an alarm module.

The specific implementation mode is as follows:

background wireless communication module: and the background wireless communication module performs wireless information interaction with the access control verification subsystem, the equipment locking subsystem and the access terminal. It is responsible for receiving and transmitting relevant information and ensuring smooth communication between the subsystems.

A memory: the memory is used for storing unique identification codes of all equipment locking subsystems in the transformer substation. These codes are used to identify the device locking subsystem and match the device location information to enable accurate localization of the problem device in the event of an anomaly.

And a data processing module: the data processing module is a main control module of the background monitoring center and processes according to the data information uploaded by the terminal of the entering person. The system sends feedback information to the access control verification subsystem to confirm the identity verification result of the entering person. At the same time, it sends unlocking information to the device locking subsystem, indicating unlocking of the corresponding device. In addition, the data processing module is also responsible for identifying the equipment locking subsystem and judging whether the equipment monitoring data has abnormality or not.

And an alarm module: and the alarm module alarms according to the judgment result of the data processing module. If the conditions such as abnormal monitoring data or identity verification failure of the equipment are found, the alarm module triggers corresponding alarms so as to take measures in time for processing.

The background monitoring center can receive, process and store information from each subsystem and the terminal of the entrant through the cooperative work of the background wireless communication module, the memory, the data processing module and the alarm module. The method can compare and process the uploaded data, and replaces the traditional manual verification by adopting a system automatic verification mode, so that the requirement on human resources is reduced.

The principle of the mode is that the background monitoring center is used as a center for data processing and control, so that information interaction and processing of the access control verification subsystem, the equipment locking subsystem and the access terminal are realized. The method can improve the efficiency and accuracy of data processing, give an alarm in time to process abnormal conditions, and ensure the safe operation of substation equipment and the timely processing of the abnormal conditions.

Specifically, the data processing module matches the identity information data uploaded by the entrance guard verification subsystem and the time data uploaded by the entrance guard verification subsystem according to the reserved identity information data and the entering time interval data uploaded by the entrance guard terminal, and if the matching is successful, the data processing module sends feedback information to the entrance guard verification subsystem; if the match fails, not as a result,

The entrance guard verification subsystem can trigger the entrance guard of the entrance guard verification subsystem to open according to the feedback information.

The data processing module firstly judges whether the time data corresponding to the entry time interval data and the uploaded identity information data are matched or not, if the time data are not in the pre-designated entry time interval range, the data processing module judges that the matching is failed, when judging that the time data corresponding to the identity information data are in the pre-designated entry time interval range, the data processing module further matches the identity information data with the reserved identity information data, and if judging that the data are matched, the data processing module sends feedback information; if the failure occurs, the failure is not taken as the result.

The data processing module is used for matching the reservation identity information data and the entry time interval data uploaded by the entry terminal, and the identity information data and the uploaded time data uploaded by the access verification subsystem. The specific implementation mode is as follows:

data matching: the data processing module firstly judges whether the time data corresponding to the time interval entering data and the uploaded identity information data are matched or not. If the entering time interval data is not in the pre-designated time range, namely does not accord with the specified entering time period, the matching is failed and is not used.

Identity information matching: if the time data corresponding to the uploaded identity information data in the time interval is in a pre-designated time range, the data processing module further matches the identity information data with the reserved identity information data. If the identity information data and the reserved identity information data are successfully matched, namely the identity verification is passed, the data processing module sends feedback information to the access verification subsystem.

The feedback information triggers the entrance guard: and the entrance guard verification subsystem triggers the opening work of the entrance guard according to the feedback information sent by the data processing module. If the identity verification is passed, the access verification subsystem performs an access opening operation, and allows an entering person to enter the transformer substation.

The principle of the method is that the data processing module is used for matching and verifying the data uploaded by the access control verification subsystem and the access terminal, so that the access terminal is ensured to meet the requirements of reservation identity and access time. If the matching is successful, namely the identity information and time of the entering person meet the requirements, the data processing module sends feedback information to the entrance guard verification subsystem to trigger the opening work of the entrance guard. Therefore, only authenticated personnel can enter the transformer substation within a specified time, and safety and accuracy are improved.

Through the mode, the data processing module can timely verify the identity and time of the entrant, so that only people meeting the conditions can enter the transformer substation, and the effect and accuracy of access control verification are improved. Meanwhile, the load of the access control verification subsystem is reduced by the mode, so that the access control verification subsystem only needs to execute the operation of opening the access control, and the response speed and the working efficiency of the system are improved.

Specifically, the data processing module sends unlocking information to the corresponding equipment locking subsystem according to the maintenance substation equipment number data uploaded by the access terminal, wherein after the access verification subsystem triggers the access opening work, the background monitoring center sends the unlocking information.

The data processing module only unlocks the substation equipment corresponding to the pre-uploaded maintenance substation equipment number, that is, the substation equipment with the pre-assigned equipment number can be operated, and other equipment is locked, so that the phenomenon that other substation equipment is operated under the condition that maintenance personnel cannot find the equipment, and the stable operation of the substation equipment is affected is avoided.

And the data processing module is matched with the equipment number uploaded in advance according to the maintenance substation equipment number data uploaded by the access terminal. The specific implementation mode is as follows:

Data matching: and the data processing module matches the maintenance substation equipment number data uploaded by the access terminal with the equipment number uploaded in advance. The data processing module triggers an unlocking operation only when the service substation equipment number matches the pre-assigned equipment number successfully.

Unlocking information transmission: and after receiving the successfully matched serial number data of the maintenance substation equipment, the background monitoring center sends unlocking information to the corresponding equipment locking subsystem. This means that only the substation equipment corresponding to the pre-assigned equipment number can be unlocked, and the other equipment is still in a locked state.

Device locking: and the equipment locking module is used for operating and locking all substation equipment with equipment numbers which are not pre-designated under the condition that the unlocking information is not received. In this way, only substation equipment matched with the pre-designated equipment number can be unlocked, and other equipment cannot perform relevant setting or operation behaviors.

In this way, the data processing module only performs unlocking operation on the pre-designated equipment number according to the maintenance substation equipment number data uploaded by the access terminal. Therefore, the operation of other substation equipment can be avoided under the condition that the maintenance personnel cannot perceive, and the stable operation and the safety of the substation equipment are ensured.

The principle of the method is that the data processing module is used for matching and verifying the number data of the maintenance substation equipment, and only the equipment number which is successfully matched can trigger the transmission of unlocking information, so that only the substation equipment with the pre-designated equipment number can operate. Therefore, unauthorized operation of equipment by non-maintenance personnel can be effectively prevented, and stable operation of substation equipment is ensured.

Specifically, after the entrance guard verification subsystem executes entrance guard opening work, the equipment locking subsystem synchronously starts to monitor the working state of the non-maintenance substation equipment, the equipment locking subsystem records the working state of the non-maintenance substation equipment at the initial time and continuously uploads equipment monitoring data in real time, and the background monitoring center identifies the equipment monitoring data and alarms after abnormal work setting is identified.

In order to reduce unnecessary data generated by the equipment locking subsystem under the condition of not manually entering the transformer substation, the data processing burden of a background monitoring center is increased, the working state of transformer substation equipment is monitored only after an entering person enters the transformer substation, and the transformer substation is required to be monitored.

After the access control verification subsystem executes the access control opening work, the equipment locking subsystem starts to monitor the working state of the non-maintenance substation equipment, and the specific implementation mode is as follows:

initial state record: and after the access control verification subsystem triggers the access control opening work, the equipment locking subsystem records the initial working state of the non-maintenance substation equipment. These initial states include operating parameters of the device, operating conditions, etc.

Uploading real-time data: the equipment locking subsystem continuously uploads the equipment monitoring data to the background monitoring center in real time. These data reflect the operating state changes of the non-maintenance substation equipment.

Abnormality identification and alarm: the background monitoring center identifies and analyzes the equipment monitoring data, and when abnormal working state setting is identified, an alarm mechanism is triggered. These anomalies may include equipment failure, abnormal operation, and the like.

In order to reduce unnecessary data volume and background processing burden, the working state of the substation equipment is monitored only after entering the transformer substation equipment. This means that real-time monitoring data of the device is only recorded and uploaded when an entry into the substation is made. Furthermore, the present solution is mainly concerned with monitoring of the entrances, since the substations are often already equipped with conventional equipment monitoring systems, which are already capable of performing the necessary monitoring of the environment and the operating state of the substation equipment.

The principle of the scheme is that the working state of non-maintenance substation equipment is monitored in real time through the equipment locking subsystem, and data is uploaded to a background monitoring center for analysis and identification. Therefore, abnormal working states can be found in time, an alarm mechanism is triggered, and safe operation of substation equipment is ensured.

The specific implementation mode is that the equipment locking subsystem records the initial state and continuously uploads real-time data, and the background monitoring center analyzes and abnormally identifies the data to realize monitoring of non-maintenance substation equipment. The scheme has the effects of improving the monitoring capability of the working state of the transformer substation equipment, ensuring the stable operation of the equipment, and alarming in time when abnormality occurs so as to ensure the safety of the transformer substation.

Specifically, the access control verification subsystem is also used for collecting the leaving information of the entrant and uploading the leaving information to a background processing center for storage, the background processing center sends the full-member locking information to the equipment locking subsystem, and all the equipment locking subsystems are restored to the operation locking state of the substation equipment.

The entrance guard verification subsystem collects corresponding leaving information when an entering person leaves, the entrance guard verification subsystem uploads data, locking information is sent to the equipment locking subsystem through the background processing center, all transformer substation equipment is locked again, and the transformer substation equipment waits for the next opening.

The entrance guard verification subsystem collects corresponding leaving information when an entering person leaves, uploads the information to the background processing center for storage, and triggers subsequent operation, and the specific implementation mode is as follows:

leaving information collection: the entrance guard verification subsystem collects corresponding departure information, such as departure time, departure position and the like, when an entering person leaves the substation.

Uploading and storing data: and the access control verification subsystem uploads the collected leaving information to a background processing center for storage and processing. The background processing center will correlate and analyze this information with other data.

And (3) sending locking information: the background processing center sends full-member locking information to the device locking subsystem. This means that all the device locking subsystems will receive this information and, on command, lock the substation devices again, i.e. restore all the devices to the locked state.

Through the mode, the access control verification subsystem can collect corresponding leaving information when an entering person leaves, and upload the information to a background processing center for storage and subsequent operation. And the background processing center sends full-member locking information to the equipment locking subsystem according to the collected information, so that all the equipment is ensured to be in an operation locking state and wait for the next opening.

The principle of the scheme is that the exit information is collected through the access verification subsystem and uploaded to the background processing center, and the background processing center triggers the whole person locking operation according to the information. This ensures that after the entry leaves, all devices are re-locked to prevent unauthorized operation.

The specific implementation mode is that the entrance guard verification subsystem collects and uploads leaving information when an entering person leaves, and the background processing center sends a locking instruction to the equipment locking subsystem according to the collected information, so that full-member locking of substation equipment is achieved. The scheme has the effects that all equipment is in an operation locking state under the condition that no entrant exists, and the safety and stability of substation equipment are guaranteed.
