Application Research On Freeway Tunnel Lighting Intelligent Power-saving Technology

In recent years,with the rapid development of highway in our country,a large number of mainly tunnels of freeway increases year by year,In order to ensure the safety and operation management needs,the tunnel electromechanical system set up more perfect function,The tunnel lighting is all the more important.But at the same time the tunnel lighting system for high power consumption,accounting for a large proportion of freeway operating costs,In the high consumption,effective energy saving energy saving is particularly important.The current freeway power grid operation is not so stable,And I can't precise to control of the power supply voltage,also,I can't do it accurately and on time control method for voltage regulation and voltage control,has caused a lot of energy waste,Lighting energy-saving automation is almost zero,So research,design,and promotion of new lighting power saving and monitoring automation management,effectively increase the power resource utilization is very timely and necessary.This article is according to the situation of Shaanxi province freeway tunnel lighting operation management method of the on-load voltage regulating,according to the research and development,designed a new type of lighting energy-saving monitoring automation system.The system integrates modern computer technology,ZIGBEE wireless network technology,measurement and control technology into an organic whole,to realize the automatic lighting intelligent management and energy saving.Through to the freeway tunnel lighting intelligent power saving and monitoring automation management system structure and working principle of analysis,Combined with the technical requirements and system functions of this system,Put forward the control strategy with fuzzy PID algorithm as the core,Designed the tunnel lighting intelligent monitor and control system for power saving of the main equipment of power saving cabinet,single lamp controller circuit diagram,terminal diagram,installation drawing,etc.Based on ZIGBEE wireless communication methods,the design of the monitoring center PC and intelligent electricity-saving ark,intelligent power saving ark and control circuit of communication between single lamp controller,Designed the monitoring automation system control interface,Finally,the system test for many lie longwan tunnel at a high speed.Through the data statistics and comparison,the system energy saving effect.Running through the freeway tunnel lighting test certificate,This article studies the design of tunnel lighting intelligent power saving and monitoring management automation system,the principle is correct,the desired research design goals,and the system runs stably,the test can meet the needs of the tunnel lighting energy saving.For highway tunnel lighting energy saving operation management puts forward a new train of thought.
