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 power consumption in building construction, aiming at the field of green energy-saving lighting, a simple and reliable building energy-saving lighting control system and a control method thereof are proposed. The system consists of PC, gateway, SCR dimming module, lights, PLC and light intensity sensor. The PLC, SCR dimming module, lamp and light intensity sensor form a closed-loop control system. The light intensity sensor feeds back the actual average illuminance in the indoor area to the PLC. The PLC will calculate the output control according to the target control value and the illuminance feedback value by using the PID algorithm Volume, SCR dimming module based on the output control of the light control, in order to achieve light brightness adjustment. Through the control of the lighting control system, the actual value of the indoor illuminance quickly reaches the illuminance setting value and is basically unaffected by external light, which achieves the effect of energy saving while maintaining the indoor illuminance at a reasonable and comfortable state.
