The present invention discloses a combined wind power generation device. By sequentially arranging a wind tube type power generation component, a vertical axis power generation component and a vertical power generation component on a main shaft from top to bottom, the device can adapt to various complex environments. After wind blows in from the air inlet of the wind tube frame, the first fan blade of the first generator drives the inner rotor to rotate, and at the same time, the second fan blade drives the outer rotor to rotate, and the rotation directions are opposite. The present invention reasonably utilizes the effect of relative motion, greatly increases the relative motion rate of the rotor and the outer rotor, has a simple and reasonable structure, and effectively improves the utilization rate of wind energy. The wind tube type power generation component, the vertical axis power generation component and the vertical power generation component are combined on the same main shaft, and the device has stronger applicability to different environments, reasonably utilizes the effective space, and has the same power generation efficiency, but occupies less space, has high energy utilization, high power generation efficiency, and a large generator stability factor.

This invention relates to the field of parking space prediction and parking guidance technology, specifically to a service area remaining parking space prediction and parking guidance method based on time-series analysis. The method includes: obtaining a comprehensive stability coefficient based on the vehicle type and any parking space type; obtaining a highway traffic flow impact coefficient based on the number of vehicles on the highway heading to the service area that match the parking space type and the parking space's vacancy time, and the corresponding number of available parking spaces; obtaining a comparison benchmark based on the historical time period, traffic density, and dwell time corresponding to the current moment; obtaining a deviation degree of traffic flow dwelling pattern based on the comparison benchmark and a preset off-peak time benchmark; obtaining the probability that a vehicle will occupy an available parking space of a certain type based on the comprehensive stability coefficient, highway traffic flow impact coefficient, and traffic flow dwelling pattern deviation degree; and guiding the vehicle based on the comparison result between the probability and a preset threshold. Using this invention, parking space prediction and parking guidance can be performed with relatively high accuracy.
