[0094] The preferred embodiments of the present invention will be described below with reference to the drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0095] An embodiment of the present invention provides a substation remote monitoring system, as Figure 1 shown, including:

[0096] An environmental monitoring module 1 for collecting monitoring data of the substation;

[0097] A video monitoring module 2 for collecting video data of the substation;

[0098] A data transmission module 3 for remotely transmitting the video data and the monitoring data to a management platform;

[0099] An abnormality judgment module 4 for judging whether there is an index abnormality in the substation based on the video data and the monitoring data. If it is judged that there is an index abnormality in the substation, the fault type is determined;

[0100] A visualization display module 5 for visually displaying the abnormal indexes to the user through the management platform;

[0101] Among them, the abnormality judgment module uses a fault type determination model pre-trained based on machine learning to determine the fault type according to the video data and the monitoring data.

[0102] The working principle and beneficial effects of the above technical solution are as follows:

[0103] The environmental monitoring module 1 sets up a temperature monitoring unit, a humidity monitoring unit, a particle monitoring unit, a current monitoring unit, a voltage monitoring unit, and a data fusion unit according to the index parameters, and respectively collects temperature data, humidity data, air particle data, current data, voltage data, etc. The environmental monitoring module 1 has multiple monitoring units, namely. The temperature monitoring unit collects temperature data through a temperature sensor. The humidity monitoring unit collects humidity data through a humidity sensor. The particle monitoring unit collects air particle data through a smoke sensor. The current monitoring unit collects current data through an ammeter. The voltage monitoring unit collects voltage data through a voltmeter. The data fusion unit is used to fuse the temperature data, humidity data, air particle data, current data, and voltage data to determine the monitoring data. The video monitoring module 2 is used to collect the video data of the substation. The data transmission module 3 remotely transmits the video data and the monitoring data to the management platform. The anomaly judgment module 4 judges whether there is an index anomaly in the substation according to the video data and the monitoring data. If it is judged that there is an index anomaly in the substation, then the anomaly index is determined. The visualization display module 5 is used to visually display the first analysis result and the anomaly index to the user. The environmental monitoring module 1 includes multiple monitoring units.

[0104] The training steps of the fault type determination model are as follows:

[0105] Collect the historical monitoring data and historical video data of the substation; In the substation environment, two types of data need to be collected first: video data and monitoring data. The video data can collect image information such as the operation of the camera equipment and the environmental status, and the monitoring data includes sensor data such as temperature, current, voltage, and equipment operation status.

[0106] Perform fault type annotation on the collected historical monitoring data and historical video data; Label the collected video data and monitoring data according to the known fault types. Usually, through experts or historical data, it is determined whether the data belongs to a certain fault type at a specific time point, such as "overload", "equipment failure", or "problems caused by environmental factors".

[0107] Use the historical monitoring data and historical video data after fault type annotation as the training dataset to train the fault type determination model. Use the labeled dataset to train the model to identify different fault types. Usually, optimization algorithms such as gradient descent method and stochastic gradient descent are used to minimize the loss function of the model, thereby optimizing the model parameters and making the performance of the model optimal on the training set.

[0108] In an embodiment of the present invention, a fault type determination model pre-trained based on machine learning is utilized to determine the fault type according to video data and monitoring data; various indicators of the substation are monitored in real time, and abnormal indicators are confirmed. Meanwhile, the abnormal data and the devices in the abnormal area are displayed through a visualization display module, facilitating maintenance by the user.

[0109] In one embodiment, the video monitoring module 2 includes:

[0110] The first moment video data unit is used to collect the first moment video data of the substation;

[0111] The second moment video data unit is used to collect the second moment video data of the substation after a future time period from the first moment;

[0112] The target locking unit is used to compare the first moment video data and the second moment video data to determine the shooting target;

[0113] The zoom adjustment unit is used to adjust the zoom factor of the video shooting so that the shooting target meets the zoom condition,

[0114] wherein the zoom condition is that the edge line of the video imaging corresponding to the shooting target in the video touches the set video boundary line;

[0115] The video acquisition unit is used to perform video acquisition on the substation when the edge line of the video imaging corresponding to the shooting target in the video touches the set video boundary line to obtain the video data of the substation.

[0116] The working principle and beneficial effects of the above technical solution are:

[0117] The first moment video data unit collects the first moment video data of the substation at time t 1 moment. The second moment video data unit collects the second moment video data of the substation after a set time period at time t 2Collect the video data of the substation at the second moment in real time. The target locking unit compares the video data at the first moment with the video data at the second moment, identifies the targets in the video, and determines the shooting targets. For example, the video data includes the transformer equipment, trees, and houses of the substation. Through comparison, it is determined that the shooting target is the transformer equipment of the substation. The zoom adjustment unit adjusts the zoom factor of the video shooting so that the shooting target meets the zoom condition. The zoom condition is that the edge line of the video imaging corresponding to the shooting target in the video touches the set video boundary line. For example, the edge line of the video of the transformer equipment of the substation touches the set video boundary line. Thus, the shooting target can be detected more precisely, thereby improving the video acquisition resolution of the video target. When the edge line of the video imaging corresponding to the shooting target in the video touches the set video boundary line, the video acquisition unit performs video acquisition on the substation to obtain the video data of the substation.

[0118] In the embodiment of the present invention, the video monitoring module collects videos, performs target recognition on the videos, and performs zooming, thereby improving the clarity of the video acquisition screen.

[0119] In one embodiment, the data transmission module 3 includes:

[0120] The index parameter sub-unit is used to determine the index parameters to be monitored for the substation;

[0121] The first transmission sub-unit is used to determine the first transmission sequence based on the index parameters;

[0122] Among them, the first transmission sequence includes a sequence header and several data storage parts corresponding to the index parameters;

[0123] The sequence header sub-unit is used to obtain the coordinates of the monitoring points of the substation and store the position point coordinates in the sequence header;

[0124] The second transmission sub-unit is used to obtain the monitoring data of the monitoring points of the substation and sequentially fill them into the data storage parts based on the first mapping relationship between the index parameters and the data storage parts to obtain the second transmission sequence;

[0125] The sequence detection sub-unit is used to detect whether the data storage parts in the second transmission sequence are filled. If the detection shows that they are not filled, it determines the blank data storage parts in the second transmission sequence, and based on the first mapping relationship, determines the index parameters corresponding to the blank data storage parts and supplements the monitoring data;

[0126] The sequence transmission sub-unit is used to send the second transmission sequence to the management platform if the detection shows that it is filled.

[0127] The working principle and beneficial effects of the above technical solution are as follows:

[0128] The index parameter subunit determines the index parameters to be monitored in the substation. For example, in this embodiment, the temperature and humidity of the substation need to be monitored. The first transmission subunit determines the first transmission sequence according to the index parameters such as temperature and humidity. The first transmission sequence includes a sequence header and two data storage parts. The sequence header is used to store the coordinates of the monitoring points in the substation. The two data storage parts are respectively used to store temperature data and humidity data. The sequence header subunit obtains the coordinates of the monitoring points in the substation and stores the position point coordinates into the sequence header. The first transmission sequence belongs to the transmission sequence of blank data. The second transmission subunit obtains the temperature monitoring data and humidity monitoring data of the monitoring points in the substation, and fills them into the data storage parts in turn based on the first mapping relationship between the temperature and humidity and the data storage parts, to obtain the second transmission sequence. The sequence detection subunit detects whether the data storage parts in the second transmission sequence are filled. If the detection shows that they are not filled, it determines the blank data storage parts in the second transmission sequence. For example, if it is found that the data storage part corresponding to the temperature is "null", it obtains the temperature monitoring data and writes it into the data storage part corresponding to the temperature. If there is no temperature monitoring data, it controls the temperature monitoring unit in the environmental monitoring module 1 to re-collect the temperature data of the monitoring points and write the temperature data into the data storage part corresponding to the temperature. If the detection shows that they are filled, the sequence transmission subunit sends the second transmission sequence to the management platform.

[0129] In the embodiment of the present invention, the data is transmitted to the management platform through the data transmission module 3, and by constructing the data transmission sequence, it is convenient to check for missing monitoring data, improves the monitoring effect, and prevents the loss of monitoring data.

[0133] wherein, the normal operation rule base includes the value ranges corresponding to several index parameters when the substation operates normally;

[0134] The anomaly judgment unit is used to judge whether the monitoring data of any point on the three-dimensional model of the substation is within the normal operation rule base based on the monitoring data;

[0135] The abnormal index unit is used to, if the monitoring data of any point on the three-dimensional model of the substation is outside the normal operation rule base, judge that the substation has an index anomaly, determine any point on the three-dimensional model as an abnormal point, and determine the abnormal index;

[0137] Anomaly region unit, configured to determine the anomaly region corresponding to the anomaly metrics based on all the anomaly points on the 3D model corresponding to the anomaly metrics;

[0138] Fault type unit, configured to determine the fault type based on the anomaly metrics.

[0139] The working principle and beneficial effects of the above technical solution are as follows:

[0140] The second mapping unit respectively constructs the 3D model of the substation and the 3D distribution map of the metrics. Based on the historical monitoring data of the substation, the rule base construction unit constructs a normal operation rule base. For example, according to the historical voltage monitoring data, it is obtained that the output voltage of the substation is less than 220V. The anomaly judgment unit judges according to the voltage monitoring data that the voltage monitoring data at point A in the substation is 240V, which is greater than 220V, so it is judged that the voltage at this point is abnormal. The anomaly metric unit determines that point A is an anomaly point and determines that the voltage is abnormal. Based on the anomaly metrics, the anomaly point unit determines all the anomaly points on the corresponding 3D model with a voltage greater than 220V, such as point B, point C, point D... Based on all the anomaly points on the 3D model corresponding to the anomaly metrics, the anomaly region unit determines the anomaly region E corresponding to the anomaly metrics, and the anomaly region E includes all the anomaly points on the 3D model. The fault type unit determines the fault type according to the voltage being greater than 220V, and determines the fault type of the reactor fault.

[0141] In the embodiment of the present invention, the fault type is determined through the anomaly judgment module 4, automatically realizing the judgment of the fault type of the substation, achieving early fault management, and improving the monitoring effect of the transformer substation.

[0142] In one embodiment, the second mapping unit includes:

[0143] 3D model sub-unit, configured to construct the 3D model of the substation based on the video data of the substation;

[0144] Metric 3D distribution sub-unit, configured to respectively determine the metric 3D distribution function corresponding to any one metric parameter based on the metric parameters and monitoring data of a number of substations, and determine the metric 3D distribution map based on the metric 3D distribution function;

[0145] Second mapping relationship sub-unit, configured to determine the second mapping relationship between the 3D model and the metric 3D distribution map based on the 3D model of the substation and the metric 3D distribution map; wherein, the metric 3D distribution function, the specific expression is:

[0146] S i =f x,y,z (a i )

[0147] In the formula, S i is the i-th index parameter b of the substation i corresponding index three-dimensional distribution function, a i is the i-th index parameter b i corresponding variable, n is the total number of index parameters, f x,y,z (a i ) is the three-dimensional distribution function of the i-th index parameter b i .

[0148] The working principle and beneficial effects of the above technical solution are as follows:

[0149] Based on the video data of the substation, the three-dimensional model subunit constructs a three-dimensional model of the substation. Based on the index parameters and monitoring data of several substations, the index three-dimensional distribution subunit respectively determines the index three-dimensional distribution function corresponding to any index parameter, and based on the index three-dimensional distribution function, determines the index three-dimensional distribution map. For example, the three-dimensional distribution function of voltage, the specific expression is:

[0150] S 1 = f x,y,z (V)

[0151] In the formula, S 1 is the three-dimensional distribution function of the voltage of the substation, V is the voltage variable, f x,y,z (V) is the three-dimensional distribution function of voltage.

[0152] Based on the three-dimensional model of the substation and the voltage index three-dimensional distribution map, the second mapping relationship subunit determines the second mapping relationship between the three-dimensional model and the index three-dimensional distribution map.

[0153] In the embodiments of the present invention, a three-dimensional model of the substation and an index three-dimensional distribution map are respectively constructed, and the second mapping relationship is determined, which can be displayed to the user through the management platform, facilitating the user to monitor.

[0179] Since there are high-voltage areas in the substation, it poses a danger to nearby people and animals. Therefore, in this embodiment, a certain safety warning range is set through the warning module to warn people or animals approaching the substation. The first target unit performs first target recognition on the video data of the substation to identify the first target. In this embodiment, the first target unit identifies electrician A, staff member B, and stranger C from the video data. The first warning unit determines whether electrician A and the staff member are safe personnel, and since stranger C is not a safe personnel, a first warning signal is issued. The second target unit performs clothing recognition on electrician A and staff member B. Electrician A is wearing anti-high-voltage electricity clothing, while B is wearing ordinary clothing. Based on clothing safety knowledge, the clothing standard unit constructs a clothing standard library. The second warning unit determines that A meets the clothing standard library, while B does not meet the clothing standard library, and then issues a second warning signal.

[0196] The maintenance control subunit is used to control the robot to perform maintenance on the substation according to the overall maintenance path.

[0197] The working principle and beneficial effects of the above technical solution are as follows:

[0198] Based on the retrieved corresponding maintenance plan, the maintenance area determination subunit determines the maintenance area H of the substation. The movement path subunit obtains the position M of the robot as the starting point of the robot movement path and determines the end point N of the robot movement path based on the midpoint position O of the maintenance area. Therefore, the robot movement path is MN. According to the retrieved corresponding maintenance plan and the end point N of the robot movement path, the maintenance path subunit determines the robot maintenance path NQ. The overall path determination subunit combines the robot movement path and the robot maintenance path to determine the overall maintenance path MNQ. The user controls the robot to perform maintenance on the substation according to the overall maintenance path through the maintenance control subunit.
