Research And Implementation Of Environmental Adaptive Building Shading Intelligent Algorithm

With the development of society in recent years,people's living standards are constantly improving,and they are increasingly concerned about establishing a healthy and comfortable office shading environment.The traditional office shading roller shutter system is basically manual mode,bad adaptability,low energy efficiency and poor comfort degree.According to the shortcomings of traditional building shading,this paper applies intelligent shading algorithm to control system to realize the intelligent building shading control system based on the environment self-adaptation.In this paper,the author firstly describes the development status of building shading,and studies the characteristics and development of shading technology at home and abroad.The author gives the frame structure and concrete implementation scheme of the system on the basis of the requirements of modern building shading system and developing different control algorithms aiming to three outdoor sky models.The author also analyzes the factors that influence the height of electric roller shutter,and puts forward the control algorithm of roller shutter and its application in intelligent building are further.Setting up space computing model,constructing simulation model based on DIALux,using Java function to calculate the height of roller shutter which under the model,so that the author gets its trajectory calculation data and simulation data,and knows the higher precision that roller shutter can achieve through the contrast analysis.Regarding the window as a light source which uniformly distributed on cloudy day,intensity of illumination,by measuring the window using calculation formula of Lambertain radiator by measuring the window illumination to get desktop illumination calculation formula.Making sure the error between the calculated value and simulation value can be controlled to less than 10%.On sunny days,control the curtain height according to the sun's position.The height of the roller shutter is calculated rely on the sun position and Lambertian radiator on mix day,and choose the final height of the curtain based on regulation.The control algorithm can make the office meet the standard illumination requirements while making full use of the sunlight.Apart from this,it is energy saving,practical and high precision.Finally,the intelligent control system of building sun shading is given software realization,and making a test to function of client.The result shows that the system can receive the parameter information of the client,and saves the information into the database to get the high value data of the roller shutter.The system client and server interface are easy to operate,stable and practical,and meet the design requirements of the system.
