The intelligent maintenance, inspection and evaluation system for wind farms according to claim 3 is characterized in that: The evaluation subsystem (3) further comprises an equipment evaluation module (302), which monitors various components in the power plant according to data obtained by the inspection subsystem (2) and the monitoring module (102), and performs equipment evaluation on the reasons for non-compliance when the project evaluation module (301) evaluates that the components do not meet the standards, so as to identify whether the reasons are equipment factors, wherein the equipment evaluation module (302) is composed of an environmental factor (302a), an equipment factor (302b) and a verification module (303c); Environmental factors (302a): The surrounding environment is detected by various sensors in the monitoring module (102), and environmental-related data such as "temperature", "illuminance", "illuminance angle", "time", "wind force", "wind direction" and other data are integrated. When the project evaluation module (301) determines that the power generation production at the current stage does not meet the standards, the surrounding environmental factors (302a) are judged to comprehensively obtain the causes of the production failure; Equipment factor (302b): The inspection subsystem (2) identifies and judges various indicators of the equipment, compares the reasonable operating temperature, current and other parameters of the equipment, integrates the parameters that are different from the reasonable operating parameters and records them as equipment factors (302b), and determines whether the production device has a fault by integrating and counting the equipment factors (302b), thereby comprehensively deriving the causes of non-compliance with production standards; Verification module (303c): By integrating the above-mentioned environmental factors (302a) and equipment factors (302b), it determines the situation that may cause the project evaluation to fail to meet the standards, and records the environmental factors (302a) and equipment factors (302b) at the time of the failure when the failure occurs or the standards are not met. After completing the recording, the environmental factors (302a) and equipment factors (302b) that caused the failure or the project failed to meet the standards for multiple times are compared to integrate and determine the cause of the failure.

6. The intelligent maintenance, inspection and evaluation system for wind farms according to claim 1 is characterized in that: The monitoring module (102) contains multiple signaling effects after receiving data: a real-time monitoring (102a) program, a power prediction (102b) program and a fault alarm (102c) program; Real-time monitoring (102a): by recording and counting data every second and generating reports based on time, staff can access the reports through the console (101a) or mobile application (101b) to detect data fluctuations in a timely manner; The power forecast (102b) is: compared with the current power through the monitoring module (102a) and its daily report record, and recorded according to the time period of year, month, day, hour, minute and second, so as to integrate the fluctuation law of daily power generation and compare it with the current power according to the law prediction; Among them, the fault alarm (102c) is: when the data detected by the real-time monitoring (102a) program and the power prediction (102b) program show a large fluctuation, the control console (101a) and the mobile application (101b) in the control terminal (101) are used to notify the staff to carry out maintenance and repair in time.
