Control method, device and system of intelligent window

Abstract

The invention discloses a control method, a control device and a control system of an intelligent window. The control method comprises the following steps of: acquiring an initial sun-shading angle, an initial sun-shading height and an initial window opening position of the to-be-controlled intelligent window, and transmitting the initial sun-shading angle, the initial sun-shading height and the initial window opening position to a comprehensive comfort index model to obtain a target sun-shading angle, a target sun-shading height and a target window opening position, wherein the comprehensivecomfort degree index model comprises a thermal comfort degree index, a light comfort degree index, an air quality comfort degree index and a sound comfort degree index, the environment comfort degreeindexes are constructed according to a mechanism model of the to-be-controlled intelligent window, and the mechanism model is related to the shading angle, shading height and window opening position of the to-be-controlled intelligent window; and controlling the to-be-controlled intelligent window according to the target shading angle, the target shading height and the target windowing position. By adopting the control method, the target sun-shading angle, the target sun-shading height and the target windowing position are determined according to the initial sun-shading angle, the initial sun-shading height and the initial windowing position, and the to-be-controlled intelligent window is controlled under the condition of multi-environment factor coupling.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a control method, device and system for an intelligent window. Background technique [0002] The building's thermal environment, light environment, acoustic environment and air quality are connected through the window system between the interior and exterior of the building. Rule-Based Control (RBC, Heuristic Control) is the conventional approach and industry standard for skin system (window) control. RBC is based on the "IF (condition)-THEN (action)" rule and introduces expert knowledge into the control loop. RBC strictly depends on the correct selection of rules and related parameters, and can only respond to a single environment, that is, when a certain environmental physical parameter exceeds the limit, it will respond. [0003] RBC control encounters relevant limitations in the prediction of building behavior, because RBC is based on predefined rules, and usual...

Problems solved by technology

[0004] In view of this, the present invention provides a smart window control method, device and system to solve the problem that the existing smart window control process is based on predefined rules, and it is usually impossible to foresee all possible situations, although parameters can be (Offline simulation) and rule learning methods are improved, but they cannot solve the coupling of windows to multiple environmental factors, and it is difficult to realize the integrated control of ventilation and sunshade, resulting in the inability to give the optimal control strategy for the comprehensive comfort of the environment.
