Each monitoring point in the target energy storage micro-grid corresponds to a video acquisition module, specifically, a plurality of monitoring points can correspond to one video acquisition module, and the video acquisition module can acquire the video of each corresponding monitoring point.

The photovoltaic power generation monitoring module can monitor the operation condition of the monitoring point position in the photovoltaic power generation system, and first operation data of each photovoltaic power generation monitoring point position are collected in real time. Here, the first operation data may be power generation current data, power generation voltage data, etc., the power generation current data may be collected by setting a current transformer at the photovoltaic power generation monitoring point location, and the power generation voltage data may be collected by setting a voltage transformer at the photovoltaic power generation monitoring point location.

The energy storage device monitoring module can monitor the operation condition of the monitoring point position in the energy storage system, and collect the second operation data of the monitoring point position of each energy storage device in real time. Here, the second operation data may be operation state data, operation temperature data, or the like. The working state data can be monitored through a voltmeter arranged at the monitoring point of the energy storage equipment, and particularly, the line voltage of the energy storage equipment can be monitored; the operation temperature data can be monitored through a temperature sensor arranged at the monitoring point position of the energy storage device, and the temperature sensor can be a patch temperature sensor and the like.

Here, the third operation data may be battery voltage data, battery temperature data, charge-discharge state data, or the like. The battery voltage data can be monitored through a voltmeter arranged at a battery pack monitoring point; the battery temperature data can be monitored by a temperature sensor arranged at a battery pack monitoring point, and the temperature sensor can be a patch temperature sensor and the like; the charge and discharge state data can be obtained by comparing current battery voltage data with historical battery voltage data.

The intelligent control terminal can receive the first operation data, the second operation data and the third operation data in real time, and meanwhile, the first operation data, the second operation data and the third operation data can be recorded, so that the operation condition of each monitoring point position can be analyzed conveniently. In addition, the intelligent control terminal can also carry out arrangement analysis on the first operation data, the second operation data and the third operation data, so as to obtain information to be displayed. The information to be displayed can comprise operation information and reminding information. The operation information is used for reflecting real-time operation conditions of the electronic elements corresponding to the monitoring points, and the reminding information is used for reflecting abnormal operation conditions of the electronic elements corresponding to the monitoring points.

The visual terminal can directly display the information to be displayed generated by the intelligent control terminal, so that a worker can directly read the operation data corresponding to each monitoring point position on the visual terminal, and timely know whether the operation of each monitoring point position is abnormal or not. In addition, the visual terminal can display the target display information according to the user requirement. Specifically, the visual terminal may be an interactive terminal, and the user may select a display category related to the requirement by clicking a mouse, touching a screen, or the like, and then the visual terminal may generate user input data according to a clicking operation, a touching operation, or the like of the user, determine target display information from information to be displayed according to the user input data, and display the target display information. Here, the operation information in the information to be displayed may be operation data corresponding to each monitoring point directly, and the reminding information may be reminding data corresponding to the abnormal monitoring point directly, for example, a device name, a device position, etc. corresponding to the abnormal monitoring point. In addition, the running information in the information to be displayed can be an identification list of each monitoring point, the reminding information can be an identification list of an abnormal monitoring point, and the like, so that a user can select information to be checked in further detail from the list by clicking a mouse, touching a screen, and the like, and at the moment, the visual terminal can take the information selected by the user as target display information according to the input data of the user, and display the target display information.

The video acquisition module can have a portrait identification function, in a specific operation process, the video acquisition module does not always monitor the surrounding environment, and only after receiving a monitoring instruction sent by the intelligent control terminal, the video acquisition module indicates that an maintainer is about to overhaul, and then the video acquisition module starts to monitor the surrounding environment. The monitoring instruction is generated by the intelligent control terminal after receiving the first reminding information returned by the client of the target maintainer, wherein the first reminding information can be related reminding information for indicating that the target energy storage micro-grid has maintenance requirements and requiring the target maintainer to go to maintenance. After receiving the monitoring instruction, the video acquisition module can start to monitor the surrounding environment, and when the human image is monitored in the surrounding environment, the video acquisition module indicates that the target maintainer has previously overhauled at the moment, and then video acquisition can be started at the moment. In addition, the video acquisition module can also receive an acquisition end instruction sent by the intelligent control terminal, wherein the acquisition end instruction is generated after the intelligent control terminal receives an overhaul completion instruction sent by a target overhaul personnel through the client, and the acquisition end instruction can be sent to the video acquisition module. After the video acquisition module receives the acquisition end instruction and ends video acquisition, a video file corresponding to the acquired video can be sent to the intelligent control terminal.

The intelligent control terminal can receive the video file and store the video file at the same time so as to be used later. The intelligent control terminal can also extract multi-frame images to be analyzed from the video file according to preset rules. Here, each frame of image to be analyzed is used for determining the corresponding maintenance action of the target maintenance personnel, so the preset rule can be an image extraction time interval determined according to the statistical analysis rule, and under the image extraction time interval, the frame number of the image to be analyzed can be ensured not to be excessive, so that the subsequent analysis calculation amount is large, and all the maintenance actions corresponding to the target maintenance personnel can be almost captured. The image extraction time interval may be determined according to the change time of the overhaul actions, for example, the time required for changing from one overhaul action to the next is generally a, and then the image extraction time interval is slightly smaller than the time a, so that the image to be analyzed obtained by extraction according to the image extraction time interval may include each overhaul action of the target overhaul personnel. The image extraction time interval may be specifically extracted from the historical service video. In addition, the preset rule can also be that the images are analyzed frame by frame according to an image similarity comparison algorithm, and when the image difference between the next frame of image and the current frame of image is larger than a preset threshold value, the next frame of image is taken as an image to be analyzed; otherwise, deleting the next frame image. For example, the first frame image is image 1, the second frame image is image 2, if the image difference between image 2 and image 1 is smaller than the preset threshold, image 2 is deleted, then the image difference between image 3 and image 1 is calculated, if the difference between image 3 and image 1 is larger than the preset threshold, then image 3 is reserved, then the image difference between image 4 and image 3 is calculated, and so on, the finally reserved image is the image to be analyzed. Here, the image similarity comparison algorithm may be a histogram algorithm, a gray-scale image algorithm, or the like.

After obtaining the multi-frame images to be analyzed, the images to be analyzed can be sequentially input into a preset fault identification model according to the occurrence sequence, and then the target fault type of the first reminding information is obtained. Specifically, the preset fault recognition model may include an image description text generation sub-model, a text fusion sub-model and a fault recognition sub-model. Wherein the image description text generation sub-model may be an IMG2 LLM model, and the input of the model is the image to be analyzed and a preset problem, in particular, the preset problem may be "what action is being performed by a target maintainer in the graph? After that, the image description text generation sub-model can output a corresponding image description text according to the image to be analyzed, wherein the image description text can comprise descriptions of actions being executed by the target maintainer. After the image description text corresponding to each frame of the image to be analyzed is obtained, the image description text can be sequentially input into a text fusion sub-model, and the image description text corresponding to each frame of the image to be analyzed is fused through the text fusion sub-model to generate a complete description text of the video file. The text fusion sub-model may be any model with text fusion function, and is not required here. After the complete description text is obtained, the complete description text is input into a fault recognition sub-model, action features in the complete description text are extracted through the fault recognition sub-model to form a target feature set, similarity calculation is conducted on the target feature set and preset feature sets corresponding to each preset fault, and preset faults corresponding to the closest preset feature sets are used as target fault types corresponding to the video files, namely target fault types corresponding to the first reminding information. Here, the action feature may be any word or the like describing the service action of the service person. According to the embodiment of the application, the corresponding target fault type of each overhaul is directly determined through the recorded video file, and compared with the determination of the target fault type according to the fault type reported by an overhaul worker, the real fault of the equipment can be more accurately determined, the condition that the real fault of each equipment cannot be identified due to the fact that the overhaul worker reports the fault at will is avoided, and the embodiment of the application is beneficial to the real fault statistics of the equipment, is convenient for the follow-up determination of the equipment improvement problem and the like. It should be noted that the preset fault recognition model can be obtained through training according to the historical overhaul video file, so that the recognition accuracy of the preset fault recognition model can be greatly improved through targeted training.

In addition, the video acquisition module can start to acquire video after receiving the monitoring instruction, can end video acquisition after receiving the acquisition end instruction sent by the intelligent control terminal, and then sends a video file corresponding to the acquired video to the intelligent control terminal. The intelligent control terminal can receive the video file, store the video file at the same time, and extract multi-frame images to be analyzed from the video file according to a preset rule. After obtaining the multi-frame images to be analyzed, the images to be analyzed can be sequentially input into a preset fault identification model according to the occurrence sequence, and then the target fault type of the first reminding information is obtained. The embodiment of the application automatically collects, monitors, early-warning analyzes and comprehensively visualizes the data of each link in the running process of the energy storage micro-grid, can help related staff to master the running condition of the energy storage micro-grid in time, has good use convenience, is convenient for the related staff to quickly carry out fault positioning, and is beneficial to improving the inspection efficiency; meanwhile, related staff can conveniently and timely identify abnormal operation conditions, and the abnormal operation conditions are arranged and treated in advance, so that the operation stability of the energy storage micro-grid can be greatly improved.

In addition, the intelligent control terminal can generate second operation information according to the first operation data, the second operation data and the third operation data. Specifically, the intelligent control terminal may acquire first historical data corresponding to the first operation data in a preset time period, where the preset time period may be a time period indicated by a time length from the current time, for example, the current time is three afternoon and the time length is 1 day, and the preset time period may be three afternoon yesterday to three afternoon. After the first historical data is obtained, the first operation trend graph can be drawn by using the first historical data and the first operation data. Since the first operational data is acquired in real time, the first operational trend graph is also updated in real time. Likewise, the intelligent control terminal may also draw a second operational trend graph and a third operational trend graph. In addition, the first operation trend chart, the second operation trend chart and the third operation trend chart can be used as second operation information to be displayed on the visual terminal. Through show the second operation information on visual terminal, can make relevant staff directly know the historical operation data and the operation change trend condition that each monitoring point position corresponds, the condition of convenient timely discovery operation trend is unusual.

The intelligent control terminal can also identify abnormal operation data in the first operation data, the second operation data and the third operation data in real time, for example, a set value is preset for each data in the operation data, for example, the first operation data can comprise power generation current data, power generation current thresholds can be preset for different photovoltaic power generation monitoring points, and if the power generation current data indicates that the power generation current corresponding to a certain photovoltaic power generation monitoring point is greater than the power generation current threshold, the power generation current data can be identified as the abnormal operation data. When the intelligent control terminal identifies the abnormal operation data, a target monitoring point position and abnormal occurrence time corresponding to the abnormal operation data can be obtained.

Here, different preset fault types may be preset, where each preset fault type corresponds to a monitoring point, for example, when the working state data is abnormal operation data, the monitoring point corresponding to the working state data is an energy storage device monitoring point, and the preset fault type may be a line fault or the like. And then, the first fault information can be used as second reminding information and can be directly displayed on the visual terminal or displayed on the visual terminal according to the user requirement.

When the third operation data comprises the charge and discharge state data and the charge and discharge state data is abnormal operation data, the fact that the monitoring point position corresponding to the charge and discharge state data has faults is indicated at the moment, the intelligent control terminal can update the second fault times corresponding to the monitoring point position, and meanwhile second fault information can be generated according to the preset fault types and the abnormal occurrence time corresponding to the charge and discharge state data.

For example, the position can be found on a preset electronic map according to the position of the target device, and the target monitoring point corresponding to the position is marked with the target device name, wherein the target device names and the devices are in one-to-one correspondence. Then, the intelligent control terminal can update the first reminding information according to the marked preset electronic map, and the updated first reminding information can comprise the marked preset electronic map and the abnormal occurrence time.

Specifically, the intelligent control terminal can receive check-in information sent by the overhauling personnel through the client, and can determine corresponding target equivalent personnel according to the check-in information. Thereafter, attendance information may be generated from the check-in information.

After the intelligent control terminal generates the first reminding information, whether the target current person is in the preset position range of the target energy storage micro-grid or not can be judged according to the current position information of the target current person at the moment, if the target current person is in the preset position range of the target energy storage micro-grid, whether the target current person is executing the task can be further judged, if the task is not executing, the target current person can be used as a target maintainer at the moment, and the first reminding information is sent to a client corresponding to the target maintainer. According to the embodiment of the application, the attendance information is automatically generated through the intelligent control terminal, the target maintainer is determined according to the checked-in target equivalent personnel, and the target equivalent personnel positioned in the preset range of the target energy storage micro-grid is selected as the target maintainer, so that the overhaul efficiency can be effectively improved.

Then, the first score can be calculated by using the overhaul duration information and the target fault types together, specifically, different overhaul level grades can be preset for different target fault types, each overhaul level grade can correspond to an overhaul duration range and a corresponding preset score, when the overhaul duration indicated by the overhaul duration information of the target overhaul personnel hits a certain overhaul duration range of the target fault type, the first score can be determined according to the corresponding preset score of the overhaul duration range. The first score enables knowledge of the maintenance level of the target maintenance person. Then, the second score may be determined according to the cumulative number of overhauls on the same day, specifically, the more the cumulative number of overhauls on the same day, the higher the second score. And finally, according to the first score and the second score, directly adding to obtain the current maintenance score corresponding to the target maintenance personnel, or obtaining the current maintenance score corresponding to the target maintenance personnel in a weighted addition mode. After the current maintenance score is obtained, the current maintenance score of the target maintenance personnel can be dynamically updated by utilizing the current maintenance score and the historical maintenance score of the target maintenance personnel.

After the fourth historical data and the plurality of fifth historical data are obtained, a preset fault prediction model can be utilized to extract data features corresponding to the fourth historical data, and in addition, the preset fault prediction model can be utilized to extract data features corresponding to each fifth historical data. In particular, the data characteristic may be an amplitude variation characteristic, a frequency variation characteristic, or the like. For the monitoring points with the same type of faults, the data features corresponding to the historical operation data in the preset time before the faults occur are higher in similarity, so that the feature similarity between the data features corresponding to the fourth historical data and the data features corresponding to each fifth historical data can be calculated. The number of feature similarities is the same as that of the fifth history data. And then, taking the history fault corresponding to the fifth history data with the highest feature similarity as a target prediction fault corresponding to the fourth history data.

Because the historical faults corresponding to the fifth historical data are overhauled, the maintenance method corresponding to the fifth historical data with the highest feature similarity can be obtained as the target maintenance method, and then the reminding information and the target maintenance method are sent to the client of the target maintenance personnel together, so that the target maintenance personnel can directly maintain according to the target maintenance method, and the maintenance efficiency can be greatly improved.

According to the embodiment of the application, the historical operation data of the similar point positions are obtained, then the abnormality of the monitoring point positions corresponding to the reminding information is determined through the historical faults corresponding to the historical operation data, and then the faults corresponding to the reminding information are maintained according to the maintenance method corresponding to the historical faults, so that fault maintenance references are provided for target maintenance personnel, and maintenance efficiency is improved.

When an inquiry confirmation instruction is received, a historical maintenance record of a target equipment name corresponding to the first reminding information is obtained, wherein the historical maintenance record comprises a historical fault type and/or a historical maintenance time;

and returning the historical maintenance record to the client.

In this embodiment, if the client side successfully receives the first reminding information, the first reminding information may be successfully fed back to the intelligent control terminal to receive the success information, and then the intelligent control terminal may send target inquiry information to the client side, so as to confirm whether the target maintainer needs to check the historical maintenance record of the monitoring point through the target inquiry information. After the client receives the target inquiry information, the target inquiry information can be displayed on the client, when the user wants to view the historical maintenance record, the user can correspondingly click a confirmation icon or a confirmation button, and then the client can correspondingly generate an inquiry confirmation instruction and return the inquiry confirmation instruction to the intelligent control terminal. After receiving the inquiry confirmation instruction, the intelligent control terminal can acquire the target equipment name corresponding to the first reminding information and the historical maintenance record corresponding to the target equipment name, wherein the historical maintenance record can be the type of the historical fault, the historical maintenance time and other information, and then the historical maintenance record can be returned to the client. According to the embodiment of the application, the target inquiry information is sent to the client to actively inquire whether the target maintainer needs to check the historical maintenance record, compared with the situation that the target maintainer can only manually check the historical maintenance record of the target equipment at present, the method and the device can facilitate the target maintainer to select and check the historical maintenance record directly through the confirmation icon or the confirmation button displayed on the pushed target inquiry information, and can help the target maintainer to quickly know the corresponding historical maintenance condition of the equipment, so that the maintenance experience of the target maintainer is greatly improved.
