[0085] By constructing these safety warning models, the large-span abandoned mine cable structure photovoltaic power station system of the present invention can achieve comprehensive monitoring and early warning of the photovoltaic power station, effectively improving the safety of the power station.

[0086] A data analysis unit is used to receive data collected by a data collection terminal, obtain real-time large-span abandoned mine cable structure data, real-time environmental data, real-time photovoltaic module performance data, real-time safety monitoring data and real-time system operation status data, substitute the real-time large-span abandoned mine cable structure data into a large-span abandoned mine cable structure safety warning model to obtain large-span abandoned mine cable structure safety warning data, substitute the real-time environmental data into an environmental data safety warning model to obtain environmental data safety warning data, substitute the real-time photovoltaic module performance data into a photovoltaic module performance safety warning model to obtain photovoltaic module performance safety warning data, substitute the real-time safety monitoring data into a safety monitoring warning model to obtain safety monitoring warning data, substitute the real-time system operation status data into a system operation safety warning model to obtain system operation safety warning data;

[0087] The data analysis unit receives the data collected by the data acquisition end in real time in the large-span abandoned mine cable structure photovoltaic power station system of the present invention, and processes and analyzes the data to obtain the current safety status and potential risks of the power station. The following is the specific workflow of the data analysis unit:

[0088] The data analysis unit first receives various real-time data from the data acquisition end, including large-span abandoned mine cable structure data, environmental data, photovoltaic module performance data, safety monitoring data and system operation status data.

[0089] The received data will be classified according to its type, such as real-time large-span abandoned mine cable structure data, real-time environmental data, etc.

[0090] The classified data will be temporarily stored in the corresponding buffer area and preprocessed, such as denoising and formatting, to ensure the quality and consistency of the data.

[0091] The data analysis unit will load various trained safety warning models from the model library, including the safety warning model of large-span abandoned mine cable structure, the environmental data safety warning model, etc.

[0092] Then, the preprocessed real-time data is substituted into the corresponding early warning model. For example, the real-time large-span abandoned mine cable structure data is substituted into the cable structure safety early warning model to evaluate the safety of the current cable structure.

[0093] Through model calculations, the data analysis unit generates various safety warning data. For example, the cable structure safety warning model outputs the current safety status score or potential risk level of the cable structure. Similarly, the environmental data safety warning model analyzes real-time environmental data, predicts the possible impact of extreme weather conditions on the power station, and generates corresponding warning information.

[0094] The data analysis unit also receives preset warning thresholds, such as cable structure safety thresholds, environmental safety thresholds, etc.

[0095] The generated warning data is compared with these thresholds to determine whether the current power plant status reaches or exceeds the warning level.

[0096] If any warning data reaches or exceeds the preset threshold, the data analysis unit will organize and summarize the warning information and transmit it to the background control terminal and the user's mobile terminal through the communication connection.

[0097] Through the real-time data processing and analysis capabilities of the data analysis unit, the large-span abandoned mine cable structure photovoltaic power station system of the present invention can achieve comprehensive monitoring and early warning of the power station safety, effectively improving the safety of the power station.

Then, the early warning unit will integrate and summarize these data to form a comprehensive safety early warning data information that reflects the current safety status of the power station.

[0101] Based on the data aggregation, the early warning unit will evaluate the aggregated security warning data according to the preset warning level standards to determine the current security warning level. The warning level may include different levels such as minor, moderate, and severe, so that relevant personnel can intuitively understand the severity of security risks.

[0102] Based on the determined warning level, the warning unit will generate specific warning information, including warning type, warning level, warning time, warning reason and recommended response measures.

[0103] The early warning unit sends the generated safety warning data information to the backend control terminal and the user mobile terminal in a timely manner through the communication connection. The backend control terminal is usually a platform for power station managers to monitor the operation status of the power station, while the user mobile terminal may be a portable device such as a mobile phone or tablet of the power station manager or relevant responsible person.

[0190] Through the above-mentioned working process of the data analysis unit, the large-span abandoned mine cable structure photovoltaic power station system of the present invention can realize the real-time reception, classification, preprocessing and early warning judgment of various types of data, and provide timely and accurate early warning information for the safe operation of the system.

[0191] Specifically, in the photovoltaic power station system for a large-span abandoned mine cable structure of the present invention, the early warning unit is also used for:

[0192] The safety warning data information is compared with the preset safety data error range value. If there is a value greater than the preset safety data error range value in the safety warning data information, the warning model corresponding to the value greater than the preset safety data error range value is marked as a model to be optimized.

[0193] Specifically, in the photovoltaic power station system for a large-span abandoned mine cable structure of the present invention, the early warning unit is also used for:

[0194] Obtain the historical data of the model to be optimized and the optimization target corresponding to the model to be optimized, optimize the model to be optimized using a genetic algorithm based on the historical data of the model to be optimized and the optimization target corresponding to the model to be optimized, obtain the optimized model, and replace the optimized safety warning model with the optimized model.

[0195] In further refining the photovoltaic power station system for large-span abandoned mine cable structures described in the present invention, the functions of the early warning unit are expanded, and it is not only responsible for generating early warning signals based on safety early warning data information, but also responsible for optimizing and updating the model.

[0196] The early warning unit receives the safety early warning data information from the data analysis unit, and compares the safety early warning data information with the preset safety data error range value. If it is found that the safety early warning data information contains a value greater than the preset safety data error range value, it means that the current model may have inaccurate predictions or performance degradation problems.

[0197] For early warning models that produce values ​​greater than the preset safety data error range, the early warning unit marks them as models to be optimized, which means that these models need further optimization to improve their prediction accuracy and performance.

[0198] The early warning unit obtains the historical data of the model to be optimized, including its past prediction results, actual observations, and possible error analysis; at the same time, it clarifies the optimization goals of the model to be optimized, such as improving prediction accuracy, reducing false alarm rate or missed alarm rate, etc.

[0199] The optimization model to be optimized is optimized using optimization algorithms such as genetic algorithms. Genetic algorithms search for optimal solutions by simulating natural selection and genetic mechanisms and are suitable for complex optimization problems. During the optimization process, the early warning unit will continuously adjust the model parameters or structure based on the historical data and optimization goals of the model to be optimized in order to seek performance improvements.

[0200] When the optimized model is obtained, the early warning unit will replace it with the corresponding early warning model in the current system; at the same time, the early warning unit will also record the process and results of the model optimization to facilitate further model improvement or optimization in the future.

[0201] Through the above-mentioned model optimization function of the early warning unit, the large-span abandoned mine cable structure photovoltaic power station system of the present invention can ensure that the early warning model used always maintains the best performance, thereby more effectively monitoring and warning of potential safety risks.

[0202] The technical solution of the present invention solves the problem that the prior art cannot provide early warning for the safety of the support system, resulting in potential safety hazards of the support system under extreme weather conditions by:

[0203] The present invention provides a comprehensive large-span abandoned mine cable structure photovoltaic power station system, including a control device end, a data acquisition end, an equipment end, a background control end and a user mobile end. This design enables the system to comprehensively monitor and manage all aspects of the photovoltaic power station.

[0204] The data acquisition end includes a variety of sensors, such as displacement sensors, stress sensors, temperature sensors, humidity sensors, and light intensity sensors, which can monitor the environmental parameters in the mine and the performance data of photovoltaic modules in real time. Current and voltage monitors and power monitors are installed on the photovoltaic modules to obtain real-time performance data of the photovoltaic modules. Cameras and infrared detectors are also installed in the mine for security monitoring to prevent illegal intrusion and potential safety hazards.

[0205] The control device receives data from the data acquisition end, and processes and analyzes the data. Five databases (the first to fifth databases) are established to store different types of data, such as large-span abandoned mine cable structure data, environmental data, photovoltaic module performance data, safety monitoring data, and system operation status data. These data are used to build multiple safety warning models, including a large-span abandoned mine cable structure safety warning model, an environmental data safety warning model, a photovoltaic module performance safety warning model, a safety monitoring warning model, and a system operation safety warning model.

[0206] The data analysis unit substitutes the real-time data into the corresponding warning model to obtain various types of safety warning data. The warning unit summarizes these warning data and compares them with the preset warning threshold. If the threshold is exceeded, a safety warning message is generated. The safety warning information is transmitted to the background control terminal and the user mobile terminal in real time, so that relevant personnel can respond quickly and take necessary measures.

[0207] The early warning unit will also compare the safety warning data information with the preset safety data error range value. If a large error value is found, the corresponding early warning model will be marked as a model to be optimized. The optimization method such as genetic algorithm is used to train and optimize the model to be optimized to improve the accuracy and reliability of the early warning.

[0208] Through the above technical means, the present invention effectively solves the problem that the prior art cannot provide early warning for the safety of the support system, and can issue early warnings in time under extreme weather conditions to ensure the safe and stable operation of the photovoltaic power station.
