The meteorological shutter is a protective device for installing a temperature and humidity instrument. Its inner and outer parts should be white. The meteorological louver box has the functions of preventing direct radiation of the sun to the instrument and reflected radiation of the ground to the instrument, protecting the instrument from being influenced by strong wind, rain, snow and the like, enabling the sensing part of the instrument to be properly ventilated and truly sensing the change of the temperature and the humidity of the outside air. The meteorological louver box is widely installed on a meteorological observation field of a meteorological station network. At present, a single platinum resistor air temperature sensor is used for measuring air temperature in ground meteorological observation service. The platinum resistance air temperature sensor measures temperature by utilizing the characteristic that the self resistance of metal platinum changes along with the change of the temperature, and the accuracy and the stability of the platinum resistance air temperature sensor depend on the characteristic of a platinum resistance element. A commonly used platinum resistance air temperature sensor uses a Pt100 resistor, the resistance value at 0 ℃ is 100 Ω, and the rate of change of the resistance is about 0.385 Ω/° c.
Only one air temperature sensor collects air temperature, and once the air temperature sensor is in failure, lightning or environmental influence or the like to cause observation data loss and influence the integrity of the data, the air temperature on the ground cannot be accurately acquired.
