Problems solved by technology

The disadvantage is that it only depends on the traffic flow to judge. If the traffic flow changes irregularly, the frequent adjustment of street light brightness will affect the service life
Publication No. CN202014396U patent "Intelligent Energy-Saving Switch Controller for Road Lighting Lamps" has the advantage that the switching time of the controller can be selected according to different regions, climates and seasons, and the actual conditions of different roads, and the idea of ​​seasonal control is proposed. The disadvantage is that it is still not sure whether the lighting conditions meet the requirements; the patent of publication number CN201230391Y "LED street lamp time division control device" divides 24 hours a day into several time periods, different time periods generate pulses of different widths, and the pulse control drive circuit lights up the LED Light, the advantage lies in the introduction of multi-level control of LED street light brightness and the concept of time division, the disadvantage lies in the lack of centralized control
Publication No. CN101861027A patent "Intelligent Centralized Control System for Street Lamps" proposes to use master-slave nodes to realize centralized control, realize overall control, local control and individual control of lighting terminals, and control the full brightness, half brightness, and Extinguish the control of the three states, but lack of effective control strategy, the degree of intelligence is not high

Embodiment 1

[0079] Example 1: figure 1 It is a structural diagram of the control system of the present invention. The intelligent sensing road LED lighting controller is composed of two parts: the regional loop controller LTU and the field node controller RTU. figure 1 Demonstrated the multi-segment lighting joint control of multiple vehicles. Among them, 24 is the first road section, 25 is the second road section, and 26 is the third road section. Each road section has a regional loop controller and multiple field node controllers, and each field node controller controls a street lamp. As can be seen:

[0080] (1) On the first road section, only one vehicle is currently driving. According to the current speed of the vehicle, the LED street lamps at the position of the car and its front and rear all have high illumination, and the remaining LED street lamps on the first road section have low illumination.

[0081] (2) In the third road section, there is only one car driving at prese...

Abstract

The invention relates to an intelligent road-perceiving LED (Light-Emitting Diode) illuminating controller. The intelligent road-perceiving LED illuminating controller comprises a zone loop controller and a site node controller, wherein the zone loop controller comprises a power module, a control core, a clock module, a human-computer interaction module, a control module selector, a system setting module, a diagnosis interface, a communication module, a traffic information acquisition module, an external information acquisition module and a display module interface; the site node controller comprises a power module, a control core, a clock module, an LED light adjusting module, a human-computer interaction module, a control interface, a system setting module, a diagnosis interface, a communication module and a display module interface; the site node controller is in two-way wireless connection with the zone loop controller; and each site node controller is connected with a corresponding LED illuminator. The intelligent road-perceiving LED illuminating controller has the advantages that the brightness of streetlamps at the road sections related to vehicle driving is controlled according to the positions of vehicles without influence on the streetlamps at the other road sections, so that the energy consumption can be greatly reduced; and the specific illumination values of the LED streetlamps and the illumination switching among the LED streetlamps are related to the current speeds of the vehicles in real time.

Description

technical field [0001] The invention relates to an intelligent perception road LED lighting controller. Background technique [0002] In the field of road lighting, most of the existing technical literature introduces high-pressure sodium lamp road lighting systems. In terms of control strategy, the road lighting management systems in most cities in China are still using simple timing control methods. These systems generally have limitations such as difficulty in feeding back street lamp operating status information and remote control, and basically have no power-saving effect. [0003] Compared with traditional high-pressure sodium lamps, LED light sources have higher energy-saving effects, and the power consumption is half of traditional light sources with the same lighting effect. In terms of lifespan, LED light sources usually have a lifespan of 50,000-100,000 hours, can be started instantly, and support continuous dimming. With the maturity of semiconductor materials...
