Building horizontal outer sun shield plate automatic control device having ventilation function and control method therefor

Abstract

The invention discloses a building horizontal outer sun shield plate automatic control device having a ventilation function and a control method therefor. The building horizontal outer sun shield plate automatic control device comprises a sensor assembly, an A / D converter, a PLC controller, a PLC controller, a sun shield plate and a ventilation sheet; the sensor assembly is used for collecting corresponding signals in real time, analog signals are converted into digital signals via the A / D converter, the digital signals are transmitted to the PLC controller, the PLC controller is used for performing logic signal processing operation according to the received real-time sensor signals, and therefore angle change control over the sun shield plate and the ventilation sheet can be finally realized. According to the building horizontal outer sun shield plate automatic control device having the ventilation function and the control method therefor, automatic control is realized via application of the PLC to a sun shield plate device, a ventilation opening and the ventilation sheet are mounted on the sun shield plate in the sun shield plate device, a sun shielding function and the ventilation function can be fulfilled, and balance between sun shielding and ventilation is attained.

Description

technical field [0001] The invention belongs to the field of building devices, and in particular relates to an automatic control device and a control method for a building horizontal external sunshade with a ventilation function. Background technique [0002] Energy-saving buildings started earlier in developed countries in Europe. The main measures are: improving the thermal insulation performance of building structures, adopting energy-saving equipment, and maximizing the use of natural energy. The natural energy referred to is mainly solar energy, and the utilization of solar energy is mainly reflected in the sunshade system of the building. After years of practice and development, developed countries in Europe have developed many sunshade products with different forms and characteristics. [0003] (1) The strip-shaped sunshade can be fixed according to the sunshine conditions in different regions and the requirements of different parts of the building. By choosing keels...

AI Technical Summary

Problems solved by technology

[0012] (1) The level of automation is not high, which reduces people's quality of life;

[0013] (2) It cannot be linked with other systems of the building, and network control cannot be realized;

[0014] (3) There is no good control of the incident sunlight

At the same time, the external sun visor of the building will directly transfer the radiant heat absorbed by itself to the external wall, which will easily cause a flow of hot air under the sun visor, thereby accelerating the transfer of heat to the interior.
