【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。更多还原

【Abstract】 Using three meteorological factors such as temperature, average wind speed,relative humidity measured by automatic weather station in real-time 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.更多还原
