[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: This invention incorporates a cloud platform, a battery management module, a data acquisition module, a wireless transmission module, a wind-solar switching module, and a debugging module. The cloud platform provides remote cloud-based data processing for the control system, centralizing data analysis and processing within the cloud platform, effectively reducing the number of data acquisition devices and lowering equipment costs. The battery management module manages batteries in partitions and isolations, facilitating subsequent battery selection and ensuring the selection of suitable energy storage batteries for debugging, comparing the charging efficiency of wind and solar power generation. The data acquisition module collects and processes battery and valve data. The wind-solar switching module handles the switching between wind and solar power.

[0017] In this invention, two batteries are reserved for the debugging module. These two batteries can be analyzed by their charge levels to eliminate the batteries with the highest and lowest charge levels, selecting the other two to ensure accurate charging efficiency assessment. This avoids the battery charge levels being too low or too high, which could affect the accuracy of subsequent analysis and judgment during debugging. When the battery charging efficiency is zero or there is a significant anomaly, the corresponding wind and solar batteries are swapped. If the charging efficiency of the swapped battery is still zero or there is a significant anomaly, it is determined that the battery has an abnormal fault, and other batteries are switched for debugging. The debugging module jumps every 30 minutes, with each debugging session lasting 5 minutes and data being checked every minute. The mode is switched only when five data points fully meet the requirements. If only three or four data points meet the requirements, the debugging time is extended by 3 minutes. The mode is switched only when at least two of these three data points meet the requirements. This effectively ensures the accuracy of the charging efficiency comparison between wind and solar power generation, thereby improving the accuracy of wind-solar hybrid switching.
