摘　　要：利用自动气象站实时测量的气温、平均风速、空气相对湿度3个气象要素作为基本参数,确定自动气象站风传感器冻结、融化的气象指标临界值,通过PC机RS232通讯接口和ATmega8型单片机、光电隔离驱动等电路控制风传感器防冻加热装置的自动运行,从而达到自动气象站风传感器防冻保护的目的。Using three meteorological factors such as temperature, average wind speed, relative humidity measured by automatic weather station in realtime as the basic parameters, the critical meteorological index for freezing and melting of wind sensor in automatic weather station was established. The wind - driven sensor antifreezing heating device was controlled for automatic operation through the PC - RS232 communication interface, ATmega8 - based single - chip and optoelectronic isolation circuit, which would realize the goal of the wind sensor antifreezeing protection in automatic weather station.
