一种新的隧道照明系统控制策略

A hovel control strategy of tunnel illumination system

目的保证隧道的运营安全,减少运营成本。方法利用PLC及组态技术,将照明系统分为手动、分段时序以及自动的控制策略,通过缩小每级的亮度变化,在视觉上实现隧道照明的连续调光。结果不仅节约电能,而且提供了安全、舒适的隧道照明,保证了车辆的行驶安全。结论通过在陕西铁炉沟隧道照明系统中采用提出的新策略,验证了其可行性。

Aim In order to ensure the safety and low cost of the tunnel operation, the control scheme of tunnel illuminating system is proposed based on PLC and Configuration technique. Methods The proposed method divides the tunnel illuminating system into manual control, time-slice senquenee control and automatic control. Results The continuous adjustment of tunnel illumination in vision is achieved through reducing the change of brightness of each level. The proposed method is not only economic but also safe and comfortable. Conclusion The feasibility of the proposed method is shown by operation in Tielugou tunnel illuminating system.
