Mobile Wind Speed and Wind Direction Measurement System of Train Vehicle

Abstract

In order to solve the ground fixed wind station can not fully measure the wind field along the railway, mobile wind speed and direction measurement system of train vehicle is required. Which need to be addressed is with the vehicle moves, the result of the measurement system is integrated wind speed, there is a need for measured wind and direction for transformation to get the real result. And the measurement system is installed on the roof of the train, the appropriate measurement method to avoid high-voltage interference is very important. The paper designed a mobile wind speed and direction measurement system by using pore air pressure measure wind speed and direction, realized speed and position measurement through the GPS module, and completed measurement of wind speed and direction data calibration and transmission by microprocessor.
