Traffic energy management and control method and system

Abstract

The invention provides a traffic energy management and control method, comprising the following steps that: acquisition equipment sends a signal to a centralized controller; the signal as a feedback signal enters into a central control room for difference comparison after being converted into a digital signal by the centralized controller, and a feedforward signal of a prediction model is corrected according to a difference; and an energy management decision system makes a decision according to the calculation result, and an intelligent fuzzy control system sends an instruction to the centralized controller and controls corresponding controlled equipment according to a protocol information execution instruction. The invention also discloses a system for realizing the traffic energy management and control method, and the system comprises the central control room, communication equipment, the acquisition equipment and the controlled equipment and also comprises the centralized controller. In the invention, the aims of safety, environment friendliness and minimum energy consumption are achieved in operation management by combining weather conditions, brightness outside a cavity, a traffic condition in a tunnel and traffic flow characteristics of a road section and the tunnel through scientific control and management.

Description

technical field [0001] The invention relates to the technical field of traffic management and control, in particular to a traffic energy management and control method and system. Background technique [0002] With the rapid development of my country's economy, the construction projects of highways and highway tunnels are increasing day by day. By the end of 2009, the number of highway tunnels in my country had increased to 3.942 million meters, including 190 extra-long tunnels with a total length of 821,100 meters and 905 long tunnels with a total length of 1.5007 million meters. my country has become one of the countries with the most, most complex and fastest-growing road tunnels in the world. Operation issues such as tunnel safety, management, and energy are becoming more and more prominent. Tunnel safety monitoring and cost control management have become important issues for the normal operation of highway tunnels in terms of safety and energy conservation. Since the 19...

AI Technical Summary

Problems solved by technology

The ability to realize automatic lighting control is very limited. Usually, due to the limitation of wiring circuits, only 2 or 3 levels of manual or automatic control can be achieved. For parameters such as weather, vehicle speed, traffic flow, etc., the maximum value is only considered in the design stage. In the end, the length and illuminance of each section of lighting are always at the maximum value

For time-varying parameters such as weather, vehicle speed, and traffic flow, it is impossible to adaptively modulate the lighting of the entire tunnel macroscopically.

Therefore, there is a large amount of waste of electric energy in the tunnel lighting system of this traditional design and use at present.

[0007] 2. The contradiction between energy saving and safety in the existing tunnel lighting control operation is prominent

[0009] 3. There is a contradiction between energy saving and tunnel monitoring in the operation of tunnel lighting control

At present, the management of longer and more complex tunnels only meets the requirements of safety monitoring, and most of the tunnels do not even meet the requirements of safety monitoring. It is basically impossible to realize energy-saving management and optimization in operation.
