摘　　要：目前自动气象站使用的湿敏电容湿度传感器和铂电阻温度传感器通常安装在百叶箱内,由于环境风速和热辐射的直接影响,常常影响测量准确度。为了较好地解决传感器的通风和防辐射问题,采用强制通风和防辐射材质以及采用垂直风道方法,结合实际使用的传感器结构和条件要求,设计成功了内嵌于百叶箱里面安装的强制通风防辐射装置,既满足了气象观测规范要求,又易于实际业务安装使用。经过性能测试,结果表明,内嵌式强制通风防辐射装置的主要性能指标达到了设计要求。At present,the humidity sensitive capacitance humidity sensor and the platinum resistance temperature sensor used in the automatic weather station are usually installed in the shutter.In order to solve the problem of ventilation and radiation sensors,with forced ventilation and radiation protection material and the vertical wind tunnel method,combined with the sensor structure and the conditions of actual use requirements.The successful design of the forced ventilation is embedded in the louvered box installed inside the anti radiation device,not only meets the specification requirements of meteorological observation,practical and easy to install and use.Through the performance test,the results show that the main performance index of the embedded forced ventilation radiation protection device meets the design requirements.
