s23, ordinary processing

Then, the signal/data processing unit in the control processing module is used for calling and classifying the signals transmitted by the data acquisition module and the environment monitoring module in real time and the data stored by the data storage unit, firstly, if the external environment humidity is in the proper range of the fan, when the signal receiving unit receives that the external environment temperature is higher than the set proper working temperature of the fan, then the heating/cooling unit can cool the inside of the cabin through the external air, if the external environment humidity is not in the proper range of the fan, the heating/cooling unit can heat/cool the blades, the cabin and the internal equipment of the cabin through self refrigeration/heating to ensure that the fan is in the proper working temperature, secondly, firstly, the signal/data processing unit is used for calling the data acquired by the environmental wind direction and speed detection unit, the pitch angle detection unit, the current detection unit, the voltage detection unit and the blade stress detection unit, then the collected data is compared and calculated with the data in the data storage unit through the signal/data processing unit, if the relative wind direction is not consistent with the value set in the data storage unit, the orientation of the cabin is calibrated by controlling the yaw protection unit through the signal output unit, if the stress of each blade is detected to be uneven by the blade stress detection unit, the data is processed through the signal/data processing unit on the basis of the data detected by the pitch angle detection unit and the strength of the wind force borne by the blade, in the process, if the stress of the blade is uneven, the angle of the blade is adjusted by controlling the pitch angle adjusting unit through the signal output unit, so that the maximum power generation is ensured under the premise that the range of the maximum wind force borne by the blade and the stress of the blade are even, thirdly, if the humidity inside the engine room detected by the temperature/humidity detection unit in the engine room is larger than the data for storage, then the exhaust dehumidification unit is controlled by the signal output unit to carry out exhaust dehumidification on the interior of the engine room, so that equipment in the engine room is ensured to work in a proper humidity environment, and fourthly, if the sand detection unit of the wind driven generator monitors that wind sand is overlarge, then the data provided by the wind speed detection unit and the pitch angle detection unit are processed and judged by the signal/data processing unit, if the wind sand is overlarge, the pitch angle of the blade can be adjusted by controlling the pitch angle adjustment unit by the signal output unit, so that the stress area of the blade is reduced, and meanwhile, the gear ratio adjustment unit is controlled to increase the gear ratio in the gear box, so that the rotating speed of the blade is reduced, and the centrifugal force borne by the tower barrel is reduced;

s24, emergency processing

If the environmental wind speed reaches the early warning level, then the data collected by the tower vibration detection unit and the cabin vibration unit are judged and processed through the signal/data processing unit, if the vibration amplitude and the frequency of the tower and the cabin are larger than the tolerance limits of the tower and the cabin, in order to avoid the influence of the blades on the tower, firstly the data fed back by the blade angle detection unit in the emergency protection module in real time are called to judge the included angle between the lowest blade and the ground, when the included angle between the blade and the ground reaches the designated range, then the blade separation unit is controlled through the signal output unit, so that the blades are separated from the cabin and the tower in a certain angle range direction in sequence, the blade is prevented from flying out to influence other fans, and meanwhile, the burden of the tower is reduced, therefore, the tower and the cabin can be reserved, in the process, if the tower topples in the tolerance limit range, then the data storage unit transmits the maximum amplitude and the frequency transmitted before the toppling of the tower to the data storage unit for storage for later analysis, and if no special reason exists, the set initial data in the data storage unit can be replaced;

s25, ecological environment protection treatment

Firstly, the signal/data processing unit calls data provided by a high-definition camera shooting unit stored by a data storage unit, if birds are close to the wind driven generator, the geographical position of a fan provided by a fan coordinate unit is firstly passed and matched with the corresponding high-definition camera shooting unit, so that a clear 3D model of the wind driven generator in a map can be obtained, then the birds are shot by the wind driven generator and the high-definition camera shooting units in the nearby wind driven generator at the same time, so that the flight route of the birds can be predicted, then the signal output unit controls the gear ratio adjusting unit in the wind driven generator adjacent to the downstream of the flight route to increase the gear ratio, so that the rotating speed of the blade can be reduced, the birds are prevented from being influenced, when the birds arrive at the downstream of the route, the shooting and the route prediction are continuously carried out, the new predicted route is used for carrying out iterative replacement on the old predicted route, and if the birds close to the large-scale migration of the wind farm are close, then the signal output unit starts the route predicting unit to stop the rotation of the blade, so that a safe migratory passageway for the birds can be opened and stopped.
