摘要
为了降低楼宇建筑中的照明用电量,针对绿色节能照明的领域,提出了一种简便可靠的建筑节能照明控制系统及其控制方法。该系统由上位机、网关、可控硅调光模块、灯、PLC和光照度传感器组成。其中PLC、可控硅调光模块、灯和光照度传感器形成一个闭环控制系统,光照度传感器将室内区域中的实际平均照度反馈至PLC,PLC将根据目标控制量和照度反馈值运用PID算法计算输出控制量,可控硅调光模块根据输出控制量对电灯进行控制,从而实现灯光亮度调节。通过该照明控制系统的控制,室内照度的实际值快速达到照度设定值并且基本不受外界光照的影响,达到了节能的效果,同时能让室内照度始终维持在合理舒适的状态。
In order to reduce the lighting electricity consumption of buildings, this paper introduces asimple and reliable energy-sewing lighting control system of building and the control method. The systemconsists of PC, gateway, silicon controlled dimmer module, lamps, PLC and illuminance sensors. The PLC,silicon controlled dimmer module, lamps and illuminance sensor constitute a closed-loop control system.The illuminance sensor feedbacks the illumination of the indoor to PLC, then PLC calculates the controloutput with PID algorithm, finally the silicon controlled dimmer module modulates the illumination of lampsaccording to the control output of PLC. With the lighting control system, the indoor illumination maintainsin a reasonable and comfortable condition without the impact of light from outdoor. It＇s in line with the requirementsof building energy efficiency.
