[0055] S400: Obtain historical data of each monitoring area, analyze the historical data, and output prediction results.

[0056] In this embodiment, the regional distribution data of the new energy station is first obtained, the new energy station is divided into multiple monitoring areas, and the sensor data of each monitoring area is received; the sensor data includes real-time power generation, power generation time curve, sunshine intensity, and sunshine intensity time curve. Then, according to the sensor data, the safety monitoring indicators of each monitoring area are calculated, and the integrated indicator data of the new energy station is fused and output. Then, the indicator safety threshold is established, and the integrated indicator data is compared and judged with the indicator safety threshold, and the judgment result is output. Finally, the historical data of each monitoring area is obtained, the historical data is analyzed, and the prediction result is output; the efficiency of obtaining monitoring results is improved, thereby ensuring the stable operation of the new energy station.

[0057] Furthermore, in the step of obtaining the regional distribution data of the new energy station, dividing the new energy station into a plurality of monitoring areas, and receiving the sensor data of each monitoring area, the specific process of dividing the monitoring area is as follows:

[0058] S101: Obtain basic information of new energy stations; the basic information includes station name, geographical location, and installed capacity;

[0059] S102: Using geographic information technology, marking the collected station information on a map to form a regional distribution map of new energy stations;

[0060] S103: determining the boundaries of the monitoring area on the area distribution map, and generating multiple monitoring areas;

[0061] S104: assigning identification data to each monitoring area; wherein the identification data includes area boundaries, name, and installed capacity.

[0062] In this embodiment, the basic information of the new energy station is first obtained; the basic information includes the station name, geographical location, and installed capacity; then, the collected station information is marked on the map using geographic information technology to form a regional distribution map of the new energy station; then, the boundaries of the monitoring area are determined on the regional distribution map to generate multiple monitoring areas; finally, identification data is assigned to each monitoring area; the identification data includes the regional boundaries, name, and installed capacity.

Then, according to the safety monitoring requirements of the new energy station, the monitoring indicators are determined; the monitoring indicators include equipment temperature indicators, environmental humidity indicators, and smoke concentration indicators. For each monitoring indicator, the value of each monitoring indicator is calculated.

[0073] In this embodiment, first, according to the monitoring target, key sensitive indicators such as equipment temperature, ambient humidity, and smoke concentration are identified. Then a safe threshold range is set for each sensitive indicator, and the threshold range is the indicator safety threshold. Then the indicator data monitored in real time is compared with the indicator safety threshold to obtain the comparison result. When the indicator data exceeds the safety threshold, the alarm mechanism is triggered, and the relevant personnel are notified by sound, light, text message, email, etc. On the monitoring interface or platform, the judgment results are intuitively displayed in the form of charts, dashboards, etc., including abnormal indicators, abnormal time, abnormal degree and other information. According to the judgment results, guide the relevant personnel to take corresponding measures to deal with it. After receiving the alarm, the relevant personnel should immediately handle the exception according to the judgment results and handling suggestions to ensure the safe operation of the new energy station. With the changes in the operating conditions of the new energy station or the update of safety regulations, the safety threshold needs to be adjusted and optimized regularly to ensure its accuracy and applicability.

[0074] Furthermore, in the step of obtaining historical data of each monitoring area, analyzing the historical data, and outputting prediction results:

Then, a statistical description method is used to draw a trend analysis chart to observe the trend of data changes over time; wherein the statistical description method includes mean, median, and standard deviation; the trend analysis chart includes drawing a line chart and a time series chart. According to the characteristics of the data and the analysis requirements, a suitable prediction model is selected, such as linear regression, time series analysis, machine learning algorithm, etc.; the prediction model is trained using historical data, and the model parameters are adjusted to improve the prediction accuracy; the trained model is applied to new data, and the prediction results are output. The prediction results are compared with the actual situation to verify the accuracy of the model. The model is optimized according to the verification results to improve the prediction performance; the current monitoring prediction results are predicted based on the historical data and output.
