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。

Abstract:

Using three meteorological factors such as temperature, average wind speed, relative humiditymeasured 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 op toelectronic isolation circuit, which would realize the goal of the wind sensor antifreezeing p rotection in automatic weather station.

Key words: automatic weather station, antifreezing;wind sensor}RS232 interface, singlechip, circuit design
