Embodiment Construction

[0020] Referring to FIG. 1 , it is a block diagram of the tunnel lighting vehicle energy-saving control device of the present invention.

[0021] Such as Picture 1-1 Shown is the block diagram of the coil type vehicle detector; Figure 1-2 Shown is the block diagram of the lighting brightness adjustment principle.

[0022] The control device includes vehicle detectors arranged at the entrance or inside of the tunnel, switches and brightness controllers provided in the lighting system, and the vehicle detectors are connected by a communication network. When there is no vehicle passing through the tunnel, the vehicle detector does not detect a signal, the lighting at the tunnel entrance section is normally on, and the internal section is turned off or the brightness is lowered; when there is a vehicle in the tunnel passing the tunnel entrance vehicle detector, the trigger control device will switch the front section of the vehicle The lights are turned on at full brightness. ...

Abstract

The control apparatus comprises a vehicle detector located at the entrance of the tunnel or at the inside of the tunnel, and a switch and brightness controller set in the illuminating system. When there is no vehicle in the tunnel, the lamp at the entrance of the tunnel is opened, and the lamp at inside of tunnel is turn off and keeps in low brightness; when there is a vehicle passing through the detector of vehicle at entrance of tunnel, the trigger device will open all lamps in front of the vehicle. The apparatus uses induction coil type vehicle detectors, which are located at the entrance of tunnel, and is buried in the ground at each interval of 100-200m.

Description

technical field [0001] The invention relates to an energy-saving control device, more specifically to an energy-saving control device for vehicle tunnel lighting, which belongs to the field of control technology. Background technique [0002] Expressway tunnels are usually equipped with tunnel lighting systems for the safety of vehicles. [0003] For expressway tunnels, according to different vehicle speed levels, the lighting in the tunnel must reach a certain brightness. This is necessary to ensure the safe passage of vehicles through the tunnel. [0004] Since highway tunnels have mandatory lighting requirements, lighting electricity costs have always been the largest cost of highway tunnel operations. Also due to the mandatory lighting requirements of highway tunnels and the randomness of vehicles passing through the tunnels, the usual lighting energy-saving control methods such as controlling the lighting brightness according to time periods cannot be used for highway...
