PLC在建筑外遮阳调控系统中设计与分析

摘要

采用PLC集成控制技术实现遮阳调控系统智能化。通过各种传感器实时自动检测光强、温度以及风力等变化，利用数学模型和建筑阴影模型，经多参量数据分析计算出合理的遮阳板角度，控制驱动电动机，统一调节建筑的室外遮阳板。利用PLC控制与遮阳板相结合，不仅可以有效减少建筑物供暖成本和空调的冷负荷，而且还可以最大限度地扩大建筑的自然采光。遮阳板的PLC控制系统可以在建筑节能领域发挥重要作用。%PLC integrated control technology is used in shading control system to realize the intelligence.This control system detects real-time data of light intensity,temperature and wind power by various sensors automatically and obtains data of appropriate shading angle through the analysis and computation of multiple parameters by using mathematical model and building shading model, then controls the drive motor to regulate building external shading together.The combination of PLC control and shading can not only reduce building heating costs and air conditioning cooling load,but also maximize the using of natural daylight.The PLC shading control system can play an important role in building energy saving area.
