Bibliography:The principle of measurement of wind speed and direction using ultrasonic time-of-flight was introduced. The design of mobile ultrasonic anemometer based on ARM-Linux and CPLD was described. The method of ultrasonic anemometer based on S3C6410 and EPM570T100C5 was given. The driving circuit, signal conditioning circuit, Linux transplantation and the software design were introduced. The experiment results show that the system can accurately measure wind speed and direction. It also has others advantages such as good reliability.
