Abstract Freezing rain in high altitude areas often causes the sensor of wind direction and wind speed to be frozen,which leads to lack of detection data.Based on the powerful function of the single chip microcomputer (SCM),an automatic heating device is designed for anti-freezing the wind direction and wind speed sensor.The SCM is used as the core controller of the entire device design,mainly including the modules of SCM control circuit,relay driver circuit,temperature acquisition circuit,electric wire control circuit and temperature display circuit etc.Through simulation test and field measurement,it is proved that the system runs reliably and effectively and solves the problem of freezing the wind direction and wind speed sensor in winter.
