Radiation-proof shield for adaptive air temperature/humidity measurement

Abstract

The invention discloses a radiation-proof shield for adaptive air temperature / humidity measurement, which comprises a solar pallet, a radiation-proof shield main body and a support, wherein a solar-cell panel is fixed on the solar pallet; the radiation-proof shield main body comprises an umbellate blade type radiation-proof shield, an air fan, a sensor and a control panel, wherein the top end of the umbellate blade type radiation-proof shield is fixedly connected with the solar pallet, and the umbellate blade type radiation-proof shield is formed into a surrounding airtight chamber structure through superposing a plurality of layers of white umbellate radiation-proof plates; the fan is arranged at the top end of the inside of the umbellate blade type radiation-proof shield; the sensor is arranged in the umbellate blade type radiation-proof shield; and the control panel is arranged on the umbellate blade type radiation-proof shield, connected with the solar-cell panel and the fan, and used for building a solar-cell photovoltaic model and an energy consumption evaluation model according to radiation values and adjusting the wind speed output of the fan. By using the radiation-proof shield disclosed by the invention, the natural ventilation and forced ventilation can be adaptively combined according to solar radiation, so that the radiation error caused by air temperature / humidity measurement can be minimized with the minimum energy consumption.

Description

technical field [0001] The invention relates to the technical field of temperature and humidity detection, in particular to an adaptive air temperature and humidity measurement radiation shield. Background technique [0002] In the measurement of air temperature and humidity in meteorology, agriculture and other fields, the direct radiation of the sun and the ground will cause errors in temperature measurement, and the influence of solar radiation is the most significant. Therefore, using louvers and radiation shields as carriers has become a conventional technical means for temperature and humidity detection. Radiation shields have the advantages of small size, light weight, and simple structure. As automatic weather stations are gradually equipped with meteorological observation networks and the urgent needs of environmental monitoring network construction, their applications are increasingly widespread. [0003] Most of the current radiation shields use natural ventilatio...

AI Technical Summary

Problems solved by technology

[0006] By adding fan forced ventilation radiation shields, many adopt barrel structure, no horizontal air circulation, uniform wind speed, comprehensive energy consumption is large, when power failure or fan failure only There is vertical ventilation, which can be regarded as a closed system in facilities and other environments, which has a great impact on the accuracy of temperature and humidity measurement

Part of the solar cell + storage battery method is just a simple integration of conventional technical means, the energy utilization rate is not high, and cannot meet the use of long-term rainy weather, and the bulky structure makes installation and maintenance inconvenient
