Description

Technical Field

[0001] This utility model relates to the field of lighting control technology, specifically to an intelligent control system for plaza lighting at highway toll stations based on traffic flow. Background Technology

[0002] A toll booth is a facility used to collect tolls from passing vehicles. Toll roads or toll-equipped interchanges must have toll booths. There are generally two types of locations for toll booths: one is directly on the main road, also known as a roadblock, often used at the start and end points of a main road toll section; the other is located at the junction or connecting road of an interchange, generally used at grade-separated interchanges between main road toll sections to control the entry and exit of vehicles from the intersecting road onto the main road.

[0003] In related technologies, the lighting control system of toll stations is used to control the lighting facilities of the toll plaza. This system turns on or off at fixed time periods, such as at night, dusk, and dawn. This continuous operation of the toll station lighting facilities results in a waste of electricity. Moreover, in special weather conditions, the lighting facilities need to be manually turned on, leading to problems such as untimely and unintelligent operation of the lighting facilities.

[0004] Based on this, this utility model proposes an intelligent control system for plaza lighting at highway toll stations based on traffic flow. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 2 The present invention provides the following technical solution: a smart control system for plaza lighting at highway toll stations based on traffic flow, the system comprising: a system main controller, an entrance photoelectric sensor, an exit photoelectric sensor, a receiver, an entrance high-mast light controller, and an exit high-mast light controller;

[0027] The photoelectric sensor at the entrance and the photoelectric sensor at the exit are used to sense vehicles at the entrance and exit of the toll station, respectively, and send the sensed signals to the receiver.

[0028] The receiver is used to send the signals sensed by the photoelectric sensor at the entrance and the photoelectric sensor at the exit to the main control system;

[0029] The main control system generates a first control signal based on the signal sent by the receiver, and sends the first control signal to the high mast light controller at the entrance or the high mast light controller at the exit.

[0030] The high mast light controller at the entrance or exit adjusts the brightness of the high mast light according to the first control signal.

[0031] For example, the main control system sends control signals to the high-mast light controller to turn the high-mast lights on or off according to preset daytime and nighttime time periods. During daytime, the high-mast lights are turned off, and during nighttime, they are turned on. At night, the brightness of the high-mast lights is generally maintained at a relatively dim level, such as 20%. When the photoelectric sensor at the entrance ramp detects an approaching vehicle, the brightness of the entrance high-mast light gradually increases to 90% and is maintained for a preset time based on traffic flow, for example, 10 minutes at a traffic flow of 5 vehicles per minute. When the photoelectric sensor at the exit ramp detects an approaching vehicle, the brightness of the exit high-mast light gradually increases to 90% and is maintained for a preset time, then automatically adjusts back to 20% brightness. In this way, the lights illuminate according to the vehicles: photoelectric sensors installed at the ramps detect passing vehicles in advance, causing the high-mast lights to change brightness accordingly. Furthermore, through entrance / exit zone control, only the brightness of the high-mast lights on the entrance or exit side changes based on the vehicle's direction of travel, minimizing power consumption.

[0032] Preferably, the main control system includes: a receiving module, a processing module, and a transmitting module; wherein, the receiving module is used to receive signals transmitted by the receiver;

[0033] The processing module is used to generate a first control signal based on the signal from the receiver, and the first control signal is used to control the brightness of the high mast light;

[0034] The sending module is used to send the first control signal to the high mast light controller at the entrance or the high mast light controller at the exit.

[0035] Preferably, the high mast light controller includes: a power switching module, a brightness adjustment module, and a switch module; wherein the switch module is used to turn on the entrance high mast light, and the brightness adjustment module is used to adjust the brightness of the high mast light.

[0036] Preferably, the system further includes: a visibility sensor for real-time sensing of air visibility, sending the sensed visibility information to a receiver, the receiver receiving the visibility information, the main control system generating a second control signal based on the visibility information, and the high mast light controller controlling the brightness of the high mast light based on the second control signal.

[0037] For example, in rainy, snowy, or foggy weather, the visibility sensor sends the detected signal to the system's main controller via a receiver. When the visibility is lower than a preset value, the main controller determines the brightness of the high-mast lights based on the visibility information, controlling the lights to turn on and adjust their brightness to correspond to the visibility level. For instance, in normal weather, if a vehicle is detected, the high-mast lights are adjusted from a "dimmed" state to 90% brightness. In abnormal weather, if a vehicle is detected, the high-mast lights are adjusted from a "dimmed" state to 100% brightness.

[0038] Preferably, the high mast light controller communicates with the main control system via wired or wireless means, the receiver communicates with the main control system via wired or wireless means, and the photoelectric sensor and visibility sensor communicate with the receiver via wired or wireless means.

[0039] For example, both photoelectric sensors and visibility sensors have wireless communication modules that transmit the detected signals to a receiver wirelessly.

[0040] Preferably, the photoelectric sensor at the entrance and the photoelectric sensor at the exit are installed on the side of the entrance ramp and the exit ramp, respectively. Preferably, the mains power supply provides power to the high-mast light controller and the high-mast light.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
