Description

Technical Field

[0001] The present invention relates to the technical field of substation monitoring and dispatching, and in particular to a substation silent monitoring and dispatching system and method. Background Art

[0002] The statements in this section merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] With the continuous development of artificial intelligence, many substations have gradually replaced manual inspections with intelligent robots and video capture equipment, achieving unmanned substation operation. By applying advanced technologies such as edge computing and big data artificial intelligence, the convenience of intelligent inspections has been improved, the risks of on-site operations have been reduced, and the level of intelligence in substation operation and maintenance management has been enhanced.

[0004] However, according to the inventors' understanding, the use of intelligent robots and video acquisition equipment to replace manual labor to complete substation equipment inspection work still has the following technical problems:

[0005] (1) The task execution method in the substation is to perform periodically according to the inspection specifications. When there is no inspection, the video acquisition equipment, including the acquisition equipment carried by the machine, is in an idle state, resulting in a waste of resources.

[0006] (2) Video equipment may have problems such as black and white screen, image color cast, low contrast, image interference, image too dark, excessive image, etc. due to network abnormalities, unstable device firmware or external interference. At this time, after the online patrol system performs the patrol task and captures the image, it will cause the patrol result analysis to fail or be wrong, reducing the accuracy of the patrol.

[0007] (3) The substation is a high-risk scene with dense power equipment and many dangerous factors. Video surveillance and manual inspections are generally used to monitor the behavior of personnel and environmental factors in the station. However, there are many video surveillance devices in the station, and the collected video data is relatively large. The staff in the station will not check the surveillance video all the time. Therefore, it is easy to miss the safety hazards in the station due to negligence or untimely inspection. Summary of the Invention

[0008] In order to address the deficiencies of the prior art, the present invention provides a silent monitoring and dispatching system and method for a substation. Without affecting the normal operation of the inspection tasks within the station, the system utilizes the inspection equipment within the station to complete the identification and early warning of abnormal personnel behavior, environmental abnormalities, video equipment abnormalities, etc., thereby realizing real-time monitoring and dynamic identification of abnormal factors within the station, saving manpower and material resources, avoiding hidden dangers and accidents caused by negligence or untimely manual inspection, and overcoming the deficiencies of the prior art.

[0009] In order to achieve the above object, the present invention adopts the following technical solutions:

[0026] After the task scheduling subsystem receives the silent monitoring task request, if there is an inspection task currently being executed, the task scheduling subsystem takes the food equipment that is not in the task and puts it into the first thread container, and then takes out the video equipment that has completed the inspection task and puts it into the second thread container;

[0027] After completing the inspection requirements of a video device in the inspection task, determine whether the video device is in the silent monitoring task. If so, put the device into the second thread container;

[0028] The silent monitoring thread sequentially takes the devices in the first thread container and the second thread container to complete the detection until the container is empty;

[0029] Complete this silent monitoring mission.

[0030] Furthermore, after the task scheduling subsystem receives the silent monitoring task request, if there is no inspection task currently being executed;

[0031] Put all video devices of the silent monitoring task into the first thread container and set the second thread container to empty;

[0032] The silent monitoring thread sequentially takes the devices in the first thread container and the second thread container to complete the detection until the container is empty;

[0049] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0050] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0051] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0052] In the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.

[0053] Example 1:

[0054] like Figure 1 and 2 As shown, embodiment 1 of the present invention provides a substation silent monitoring and dispatching system, the structure of which includes:

[0055] The task scheduling subsystem, including the data storage center, scheduling unit and monitoring unit, realizes the concurrent scheduling of inspection tasks and silent monitoring tasks, ensuring that the silent monitoring tasks are completed without affecting the patrol tasks within the station.

[0056] Patrol processing subsystem, including:

[0057] The inspection host, network DVR, video equipment, and robotic devices are connected via a switch. Routers and security access devices can also be added as needed. The inspection backend is responsible for model management, message distribution, task execution, real-time data analysis and storage, pattern recognition, and file storage. The DVR aggregates HD video from fixed points and robotic devices for video monitoring and storage. The robots, including outdoor wheeled robots and indoor track-based robots, support autonomous inspection capabilities such as autonomous navigation, offline detection, automatic retesting, and autonomous return to home in the event of an abnormality.

[0058] The video analysis subsystem includes a video acquisition unit and a video recognition unit. The video acquisition unit uses the video equipment installed in the substation to monitor the personnel, environment, and video equipment in key areas of the station. The video recognition unit uses the video recognition algorithm based on the collected video information to perform online analysis of the abnormal characteristics of the personnel, environment, and video equipment in the substation, and sends the analysis results to the early warning subsystem.

[0059] The early warning subsystem includes early warning analysis and early warning confirmation. Upon receiving abnormality messages from the video analysis system, the early warning analysis module determines the type and level of the warning and conducts secondary data mining and analysis based on big data, further categorizing and processing warnings by region. The warning results are sent to the patrol processing system interface to prompt the user. After the user processes the warning information, the patrol processing system sends a warning cancellation message to the early warning subsystem. The warning confirmation module then cancels the alarm status of the warning device and stores it in the database.

[0060] The early warning subsystem will also conduct in-depth mining of the early warning information. First, based on the early warning information of different monitoring devices, it will analyze the early warning records of each device to form monthly, quarterly, and annual reports. In fact, based on the different early warning levels, it will analyze the probability of different early warning types to form monthly, quarterly, and annual reports. Combining the above information, it will form an equipment health status table and an environmental behavior analysis table for station personnel.

[0061] Example 2:

[0062] like Figure 3 As shown, embodiment 2 of the present invention provides a substation silent monitoring and scheduling method, which specifically includes the following steps:

[0063] Step 3-1: The silent monitoring service initiates a silent monitoring task request to the task scheduling system.

[0064] Step 3-2: After receiving the silent monitoring task request, the task scheduling system first determines whether there is a remote intelligent inspection task being executed in the current system.

[0065] Step 3-3: After judgment, if the inspection task exists, go to step 3-4; if not, go to step 3-10.

[0066] Step 3-4: The scheduling system takes all the video devices in the silent monitoring task and puts them into thread container 1, and then removes the patrol devices included in the current inspection task to form the current executable video device set of the silent monitoring system.

[0067] Step 3-5: Query the video devices whose inspection tasks have been completed and put them into thread container 2.

[0068] Step 3-6: After the current inspection task thread completes the inspection instruction and inspection content of each video device in the inspection task, it determines whether the video device is in the silent monitoring task.

[0069] Step 3-7: After determination, it is included in the silent monitoring task, and proceed to step 3-8.

[0070] Step 3-8: The scheduling system places the video device into thread container 2.

[0071] Step 3-9: The silent monitoring task thread sequentially takes the video devices in thread container 1 and container 2 to perform video acquisition according to the silent monitoring configuration until both containers are empty, completing this silent monitoring task.

[0072] Step 3-10: The scheduling system places all video devices of the silent monitoring task into thread container 1, sets container 2 to empty, and enters step 3-9 until the silent monitoring task is completed.

[0073] Step 3-11: When the task scheduling system receives the station inspection task request sent by the inspection processing system.

[0074] Step 3-12: After receiving the inspection task request, the task scheduling system first determines whether there is a silent monitoring task being executed in the current system.

[0075] Step 3-13: After judgment, if a silent monitoring task exists, proceed to step 3-14; if not, proceed to step 3-16.

[0076] Step 3-14: The scheduling system places the video device whose silent monitoring task is not completed into thread container 1.

[0077] Step 3-15: Query the video devices included in this inspection task and remove them from thread container 1.

[0078] Perform steps 3-6 to 3-9 in sequence to complete this silent monitoring task. During the execution of the silent monitoring task, it is executed in parallel with the inspection task, and the silent monitoring task is completed without affecting the operation of the inspection task.
