Figure 1 As shown, the method specifically comprises the following steps:

[0027] Step S102: acquiring linkage data information of the primary and secondary monitoring systems of the substation, and generating a trigger signal based on the linkage data information.

[0028] Step S104, based on preset rules and strategies, screening the patrol points and front-end devices corresponding to the trigger signal.

[0029] Step S106, managing and organizing the control mode of the front-end device based on the hybrid execution mode.

[0030] Step S108, based on the control mode, dynamically lock the corresponding front-end device during the linkage execution, and verify the ownership relationship of the control instructions during the linkage execution.

[0031] Step S110, when the linkage status of the front-end device is task completion or locking time is over, unlocking the front-end device.

[0032] Optionally, in the embodiment of the present invention, the front-end device includes: an integrated camera system or a front-end video host and peripheral devices, a camera and a pan / tilt device, etc. It mainly realizes the functions of information collection, two-way transmission, control, etc. of audio, video, data, alarm and status.

[0033] Optionally, in an embodiment of the present invention, the front-end device related controls include: pan / tilt control, preset position control, video control, image acquisition control and audio control, etc.

[0034] In an optional implementation manner provided by the present embodiment, the linkage data information includes: a master device remote control preset signal, a master device position change signal, a master and auxiliary device monitoring over-limit signal, a master and auxiliary device monitoring alarm signal, and online monitoring data.

[0035] Specifically, the main equipment linkage information includes: remote control preset linkage information of primary equipment; position change signal linkage information of primary equipment such as circuit breakers, isolating switches, and grounding switches; non-electrical quantity alarm signal linkage information of primary equipment such as main transformers and circuit breakers; total alarm signal linkage information after the fusion of single primary equipment; protection action tripping signal linkage information.

[0036] The linkage information of auxiliary equipment includes: remote control start command linkage information of lighting, fans, air conditioners, water pumps and other equipment; remote signal change signal linkage information of fire protection, security electronic fence, access control failure and other equipment; various online monitoring, SF6, oxygen and other telemetry alarm signal linkage information.

[0037] Specifically, step S102 also includes the following steps:

[0038] Step S1021, directly generating a trigger signal for the master device remote control preset signal, the master device position change signal, the master and auxiliary device monitoring over-limit signal, and the master and auxiliary device monitoring alarm signal;

[0039] Step S1022, analyzing data features based on online monitoring data and preset judgment conditions, and generating a trigger signal when the trend change of the data features exceeds a preset threshold range or the data features are abnormal.

[0040] Specifically, a trend analysis is performed on the online monitoring data, and the defect trend, fault characteristics and defect nature are analyzed based on the input data and the preset judgment conditions set in advance, and then a linkage trigger signal is generated; a comprehensive analysis is performed on the online monitoring data, as well as the input data and the preset judgment conditions set in advance, and the characteristics of the online monitoring data are analyzed. If the trend change exceeds a certain threshold range or there is an obvious abnormality, a linkage trigger signal is generated.

[0041] In an optional implementation provided by an embodiment of the present invention, the preset judgment condition includes using historical data for trend analysis to determine the status and performance changes of the front-end device. Data comparison items can be customized based on the number of comparisons with historical data. For example, Figure 2 is a data trend comparison configuration diagram provided according to an embodiment of the present invention, such as Figure 2 As shown, the comparison rules include greater than, greater than or equal to, equal to, less than, and less than or equal to.

[0042] Specifically, the preset rules and strategies include relationship mapping and data screening;

[0043] Relationship mapping includes: a many-to-many relationship between patrol points and front-end devices, and a one-to-one relationship or a one-to-many relationship between trigger signals and patrol points.

[0044] In the embodiment of the present invention, one linkage trigger signal can establish one or more patrol points; one front-end device can establish multiple patrol points, and at the same time, one patrol point can correspond to multiple front-end devices for patrol inspection. The present invention automatically sorts out the relationship between the patrol points and front-end devices that have been set, and the linkage trigger signal and the patrol points.

[0045] Data screening includes: based on the patrol points and relationship mapping configured by the trigger signal, screening the patrol points and front-end devices corresponding to the trigger signal.

[0046] In the embodiment of the present invention, the hybrid execution mode includes a serial control execution mode and a parallel control execution mode. Specifically, step S106 also includes the following steps:

[0047] Step S1061, when one front-end device corresponds to multiple patrol points, the execution mode of the front-end device is a serial control execution mode;

[0048] Step S1062, when each front-end device performs patrol point, the execution mode of the front-end device is the parallel control execution mode.

[0049] In the embodiment of the present invention, the efficiency of linkage control can be improved through a hybrid execution mode of serial and parallel execution. The hybrid mode allows multiple tasks to be executed simultaneously, while retaining the flexibility of executing tasks in sequence, thereby better meeting the needs of different linkage operations and improving the overall response speed and performance of the system.

[0050] Specifically, in step S108, the related front-end devices during the linkage execution are dynamically locked, including: dynamically locking the related front-end devices during the linkage execution according to the corresponding hybrid mode.

[0051] Specifically, when it comes to executing patrol equipment, a lock signal and lock time are sent to prevent other control interference.

[0052] Modules transmit messages through the message bus. The interactive content is in JSON format. The sending device lockout is specified as follows:

[0053] {

[0054] "CommandType":"Request",

[0055] "SessionID":"000024",

[0056] "InstanceID":"00002",

[0057] "From":"WebService",

[0058] "To":"SrvVideoCtl",

[0059] "Time":"20240527140401997",

[0060] "Command":"LinkageLock",

[0061] "Body":{

[0062] "DeviceID":"17126256272771",

[0063] "Duration":"60"

[0064] }

[0065] }

[0066] Equipment not involved in the patrol remains unlocked to ensure optimal use of system resources.

[0067] Specifically, in step S108, the attribution relationship of the control instructions during the linkage execution is verified, and the following steps are also included:

[0068] Step S1081, when executing the control instruction of the front-end device, checking the locking state of the front-end device and the InstanceID of the control instruction;

[0069] Step S1082, if the front-end device is in a locked state, check whether the InstanceID of the control instruction belongs to the intelligent linkage instance; if yes, allow the control instruction to execute, if not, refuse to execute the control instruction.

[0070] Specifically, first control and record the InstanceID of each control module; when executing the control instruction of the front-end device, first check the blocking state. If the front-end device is in the blocking state, further verify whether the InstanceID of the control instruction belongs to the intelligent linkage instance. If the verification passes and it belongs to the linkage task, it is allowed to execute; otherwise, it is rejected.

[0071] Optionally, if the front-end device is not in a locked state, the control function can be executed regardless of the InstanceID of the control instruction.

[0072] Specifically, when the linkage state of the front-end device is task completion or the locking time is over, the front-end device is unlocked to restore it to a normal operating state.

[0073] In an optional implementation provided by an embodiment of the present invention, the control instruction for actively unlocking the front-end device is sent as follows:

[0074] {

[0075] "CommandType":"Request",

[0076] "SessionID":"000024",

[0077] "InstanceID":"00002",

[0078] "From":"WebService",

[0079] "To":"SrvVideoCtl",

[0080] "Time":"20240527140401997",

[0081] "Command":"LinkageUnLock",

[0082] "Body":{

[0083] "DeviceID":"17126256272771"

[0084] }

[0085] Optionally, the method provided by the embodiment of the present invention further includes: if the linkage module of the remote intelligent patrol system fails or crashes, unlocking the front-end device.

[0086] From the above description, it can be seen that the present invention provides a front-end device control method for intelligent linkage of substations, which has an efficient device management and scheduling mechanism, simplifies control operations, and improves overall operating efficiency; at the same time, it has the function of autonomously locking and unlocking devices to ensure the stability and continuity of the system.

[0090] The strategy analysis module 20 is used to screen the patrol points and front-end devices corresponding to the trigger signal based on preset rules and strategies.

[0091] The management and organization module 30 is used to manage and organize the control mode of the front-end device based on the hybrid execution mode.

[0093] The unlocking control module 50 is used to unlock the front-end device when the linkage state of the front-end device is task completion or locking time is over.

[0094] Specifically, the unlocking control module 50 is also used to unlock the front-end device if the linkage module of the remote intelligent patrol system fails or crashes.

[0095] Optionally, the system provided by the embodiment of the present invention further includes a central control module 60 for overall coordination and control.

[0096] In an optional implementation provided by an embodiment of the present invention, inter-module message communication adopts the Kafka publish-subscribe mode, which is suitable for one-to-many communication and is often used in scenarios such as event processing, logging, and real-time notification.

[0097] Furthermore, the inter-module message communication mode helps decouple modules and improve the scalability and maintainability of the system.

[0098] Specifically, the communication process defines:

[0099] Each module communicates messages between modules through subscription and publishing channels.

[0100] Through the publish-subscribe model, each module can flexibly subscribe and publish messages to achieve one-to-many communication.

[0101] Message transmission adopts the Kafka publish-subscribe model, which supports large-scale, high-throughput message publishing and subscription.

[0102] Structured messages are encapsulated in a unified JSON format to ensure the uniformity, readability, and ease of parsing of the messages.

[0103] Optionally, in an embodiment of the present invention, the structured message is encapsulated in a unified JSON format to ensure uniformity, readability and ease of parsing of the message.

[0104] Specifically, the use of the JSON format enables messages to maintain a consistent structure and format when transmitted between modules, making it easier for different modules to parse and process data, thereby improving the reliability and maintainability of the system.

[0105] Specifically, the application protocol definition is shown in Table 1:

[0106] Table 1 Application protocol definition table

[0107]

[0108]

[0109] Specifically, the application protocol parameters are explained:

[0110] Command type: According to the message function, JSON can be divided into the following categories: message request (Request), message response (Response), emergency report (Message), and heartbeat interaction (Heartbeat).

[0111] Instance number: the instance ID of the module. The instance ID is allocated and managed by the central control module 60. The unit module sends the instance ID of the registration message to the central control module 60. When the service is interrupted, it needs to be re-acquired.

[0112] Session sequence number: The request message is incremented by 1 each time, and the response message needs to bring back the session sequence number in the request message to identify the request and response transactions.

[0113] Command instruction name: Different command instructions are specified according to different control functions.

[0114] Time: The time when the message is sent, in the format of "yyyyMMddHHmmssZZZ".

[0115] Specifically, the Json protocol format:

[0116] {

[0117] "CommandType":"Request",

[0118] "InstanceID":"00001",

[0119] "SessionID":"00001",

[0120] "From":"xxx",

[0121] "To":"xxx",

[0122] "Command":"xxx",

[0123] "Time":"yyyyMMddHHmmssZZZ",

[0124] "Body":{

[0125] "param1":"value1",

[0126] "param2":"value2"

[0127] },

[0128] "ResBody":{

[0129] "param3":"value3",

[0130] "param4":"value4"

[0131] },

[0132] "Result":true,

[0133] "ResultCode":200

[0134] }

[0135] Table 2 Response result coding definition table

[0136] Response result code definition 100 Need to resend 200 success 400 reject 500 mistake

[0137] Optionally, in an embodiment of the present invention, each unit module sends registration, heartbeat and other interactive information to the central control module 60, and the central control module 60 responds after receiving the message. The registration-heartbeat request response process is as follows: Figure 4 shown.

[0138] Specifically, each unit module sends registration information to the central control module 60, and the central control module 60 provides a unique instance ID as an identifier. At the same time, a registration success or failure message is returned.

[0139] If the registration is successful, each unit module will carry the instance ID and send heartbeat information to the central control module 60 at regular intervals to indicate that the module is operating normally.

[0140] The central control module 60 is responsible for real-time management of the instance ID. If the heartbeat message is not sent for three times, it is considered that the link of the unit module is interrupted and the unit module needs to be re-authenticated and registered.

[0141] Optionally, in the embodiment of the present invention, the unit module performs message interaction through the assigned instance ID in daily operation. All messages adopt the standard JSON protocol format, including message request, response, burst report and heartbeat interaction.

[0142] The communication between the modules is more standardized and efficient. At the same time, the central control module 60 can flexibly manage and coordinate the working status of each unit module to ensure the stability and continuity of the system.
