DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] To make the content of the present invention easier to be clearly understood, the following will further elaborate on the present invention according to the detailed implementation manners and in combination with the drawings.

[0017] Figure 1 It is a schematic flowchart of the intelligent acoustic-optic alarm method based on the integrated main and auxiliary substation platform provided by the embodiment of the present application. The method specifically includes the following steps: Step S101: Obtain alarm data during the operation of different subsystems of the substation.

[0018] Specifically, the platform data center realizes the collection and aggregation of main and auxiliary alarm data of all substations within the jurisdiction. Among them, the data types include not only traditional four-remote signals, but also various types of data such as video, access control, fire protection, and on-line monitoring.

[0019] Among them, the platform data center application divides different applications distributed in various places and stations into security zone 1, security zone 2, and security zone 3 through single-mode optical fiber. Security zone 1 is the production control area, and security zones 2 and 3 are the management areas. Security zone 1 mainly accesses the integrated automation system and the SVC control system. Security zone 2 accesses data such as on-line monitoring, electric quantum subsystem, protection information substation, and fire protection. Security zone 3 accesses data such as video, access control, and inspection robots. Security zone 1 and security zone 2 are isolated from each other in one direction through a forward isolation device to ensure data security; security zone 2 and security zone 3 are isolated through a firewall.

[0020] Step S102: Process the alarm data and determine whether an alarm operation needs to be executed.

[0021] Specifically, a custom programming method is adopted to manage alarm data in ways such as condition triggering, parameter setting, linkage control, remote control, linkage video, telemetry signal merging, fault location and diagnosis, abnormal data processing, and dead data fitting.

[0022] The alarm data processing adopts a hierarchical progressive data processing method, including data input layer → custom script parameter setting → trigger by conditions → linkage control (remote control management, linkage video capture) → linkage information feedback → merge telemetry signals → fault location → diagnostic analysis → abnormal data processing, dead data fitting → processed signal output. See Figure 2 , and the specific operation steps are as follows: First, receive multi-source original alarm data, such as sensor signals, equipment status codes, etc. Then, configure dynamic parameters and rules through custom programming, trigger linkage control according to conditions, and integrate multi-modal data. Subsequently, perform fault diagnosis and data repair. Finally, output the structured management results and feedback signals.

[0023] Among them, the logic of custom programming parameter setting is as follows: The parameter setting module provides programmable configuration parameters such as dynamic thresholds and linkage rules. The condition trigger module continuously matches alarm data with preset conditions (such as over-limit values and mutation rates) to generate alarm events with tags. Linkage control adopts a multi-branch collaborative processing method. The parallel execution logic includes device linkage control (automatically operating associated devices according to the alarm type), remote control instructions (sending operation commands to remote terminals through MQTT / Modbus protocols), and linkage video capture (triggering the monitoring system to record the on-site video of the event and binding it to the alarm log for storage). The collaboration rule is that multi-branch control instructions are determined by priority (such as fire alarms taking precedence in device linkage) to avoid instruction conflicts.

[0024] The progressive processing of remote signal merging and fault diagnosis specifically includes the following steps: a. Data integration: The remote signal merging module aggregates heterogeneous data such as device status, sensor data, and video records to generate timestamped structured logs.

[0025] b. The integrated data is sequentially executed: topological mapping to locate the fault point → AI model to diagnose the fault type → abnormal data cleaning / annotation → dead data fitting compensation.

[0026] c. Abnormal handling closed-loop: The diagnosis result is fed back to the parameter setting module to optimize subsequent trigger conditions (such as adjusting the failure tolerance of sensors).

[0027] Step S103: Perform hierarchical processing on the alarm data that needs to execute alarm operations to determine the risk level corresponding to the alarm data.

[0028] Specifically, first, add accident cause tags to each piece of alarm data. Classify according to the accident cause into protection trip accidents, grounding accidents, power factor anomalies, voltage over-limit, reverse power supply, demand alarm, and three-phase load imbalance. Then, perform automated configuration and hierarchical classification of alarm strategies on the processed alarm information. Classify into three types according to the accident type level: level one, level two, and level three. Among them, level one represents major emergency accidents with the highest priority, level two represents emergency accidents with the second highest priority, and level three represents general accidents with the lowest priority.

[0029] Step S104: Determine the corresponding alarm execution element based on the risk level corresponding to the alarm data and control its operation.

[0030] Specifically, distribute control instructions to the corresponding alarm execution elements according to the level of the alarm data. The alarm execution elements include alarm light control elements, alarm sound control elements, alarm hosts, and alarm photon signs.

[0031] When the risk level corresponding to the alarm data is level one, the alarm light control element is controlled to flash red; the alarm sound control element is controlled to broadcast the alarm content at the first frequency, and at the same time the alarm sound control element triggers the light strips on the duty desk and the duty room to flash red; the alarm host is controlled to display the accident location, alarm content, and the corresponding equipment video of the alarm linkage, and the duty personnel manually confirm the alarm signal; the alarm photon board is controlled to push the alarm category as "major emergency accident", and before the on-site accident signal is released, the alarm sound and light content of the duty room cannot be restored by pressing the reset button.

[0032] When the risk level corresponding to the alarm data is level two, the alarm light control element is controlled to flash yellow; the alarm sound control element is controlled to broadcast the alarm content at the second frequency, and at the same time the alarm sound control element triggers the duty seat desk and the duty room light strip to flash yellow; the alarm host is controlled to display the accident location, alarm content and alarm linkage corresponding equipment video, the duty personnel manually confirm the alarm signal, and the alarm photon board is controlled to push the alarm category as "emergency accident".

[0033] When the risk level corresponding to the alarm data is level three, the alarm host is controlled to display the alarm information, and the on-duty personnel can enter the alarm history list after manual confirmation in batches.

[0034] Figure 3 A schematic diagram of an intelligent sound and light alarm system based on a main and auxiliary integrated platform of a substation provided in an embodiment of the present application. The system includes: a platform data center module, an alarm data management module, an alarm classification module, and an alarm intelligent distribution module.

[0035] Specifically, the platform data center module is used to obtain alarm data during the operation of different subsystems in the substation. The platform data center application uses single-mode optical fiber to divide different applications distributed in various places and stations into safety zone 1, safety zone 2 and safety zone 3. Safety zone 1 is the production control area, and safety zone 2 and safety zone 3 are management areas. Safety zone 1 is mainly connected to the integrated automation system and SVC control system. Safety zone 2 is connected to online monitoring, power subsystem, security substation, fire protection and other data. Safety zone 3 is connected to video, access control, inspection robot and other data. Safety zone 1 and safety zone 2 are isolated from each other through a forward isolation device to ensure data security; safety zone 2 and safety zone 3 are isolated by a firewall.

[0036] The alarm data management module is used to process the alarm data and determine whether an alarm operation needs to be performed.

[0037] The alarm classification module is used to classify the alarm data that needs to perform alarm operations and determine the risk level corresponding to the alarm data.

[0038] The alarm intelligent distribution module is used to determine the corresponding alarm execution element based on the risk level corresponding to the alarm data and control its operation. Among them, the alarm execution element includes the alarm light control element, the alarm sound control element, the alarm host and the alarm photon sign.

[0039] Specifically, the alarm intelligent distribution module is used to control the alarm light control element to flash red when the risk level corresponding to the alarm data is level one; control the alarm sound control element to broadcast the alarm content using the first frequency, and at the same time, the alarm sound control element triggers the duty seat and the duty room light strip to flash red; control the alarm host to display the accident location, alarm content, and the corresponding equipment video of the alarm linkage, and the duty personnel manually confirm the alarm signal; control the alarm photon board to push the alarm category as "major emergency accident", and the alarm sound and light content of the duty room cannot be reset by pressing the reset button before the on-site accident signal is released; when the risk level corresponding to the alarm data is level two, control the alarm light control element to flash yellow; control the alarm sound control element to broadcast the alarm content using the second frequency, and at the same time, the alarm sound control element triggers the duty seat and the duty room light strip to flash yellow; control the alarm host to display the accident location, alarm content, and the corresponding equipment video of the alarm linkage, and the duty personnel manually confirm the alarm signal, and control the alarm photon board to push the alarm category as "emergency accident"; when the risk level corresponding to the alarm data is level three, control the alarm host to display the alarm information, and the duty personnel can enter the alarm history list after manual batch confirmation.

[0040] Therefore, the technical solution of the present application defines alarm signal data management, alarm signal stratification and classification, alarm signal distribution, and alarm signals, so as to effectively solve the problem that the original alarm signals are cluttered and cannot serve as warnings and rapid disposal, thereby ensuring safe, stable and efficient operation of the power system.
