Development and Test of Software Method to Achieve Constant-Temperature-Difference Control for Thermal Wind Sensor
摘要
Abstract
A software method for controlling constant temperature difference(CTD)mode for the thermal wind sen⁃sor has been presented. As control unit,MCU is utilized to sample ambient temperature and chip temperature and adjust the power for output in order to maintain the state of CTD. The experiment shows that by means of the soft⁃ware method for control,the thermal wind sensor could almost maintain the output constant during the temperature range from-20℃to 40℃. Besides,it can measure the wind speed during 0~20 m/s with relative error less than 8%which has a response speed of less than 15 seconds.关键词
