Research On Shading Control System In Intelligent Building

As energy sources scarcity of the world and the continuous appearance of slap-up building, using inartificial energy by means of reasonably and efficiently was catching more and more people's attention.This article illuminated the feasibility and ingenuity of intelligent shading control system based on LonWorks field bus from researching the actuality of shading technique both home and abroad,and developed the shutter control device's hardware, software and the upper monitoring system, which achieved the intelligent building shading control. The following sections were the main points of this article.1. Hardware and software design and exploitation of the intelligent control device based on LonWorks technology. Every device whose core is Neuron 3150 control module could control 2~3 shading shutters.2. Software design of the synthetically control device, which forecast the elevation and azimuth of the sun based on insert value weight arithmetic.3. Monitor Control system design of the upper machine, which has both administrator and user pattern subsystem based on Visual Basic 6.0 and LNS interface technology.4. Forecast the elevation of the sun based on ANN. The forecasting capability of RBF ANN was considered rather better than the insert value weight arithmetic and BP ANN through the results of experiment.The research ultimately developed an intelligent shading control system under the lab conditions, which achieved shutter's intelligent control using the elevation and azimuth of sun and fire warning signal as parameter, and supported user manual control as well. In a word, the system made an efficient use of sunlights.
