Description

Technical Field

[0001] This invention relates to the field of low-level lighting early warning system technology, and more specifically to an intelligent control system for a road lighting system. Background Technology

[0002] Existing road lighting systems can only control the lights to be turned on at set times by system control switches. When the lights are dim during the day, or when the natural light is bright at night, or when no one or other living beings are passing by, the turning on of the lights depends entirely on manual control. Especially at night when no one is passing by, the existing lighting control system is prone to misjudgments due to occasional fluctuations in the light threshold (such as a dim and bright state) and instantaneous fluctuations (in conjunction with software delay judgment), which often leads to energy waste. Summary of the Invention

[0003] To address the intelligent control problem of road lighting systems, this patent provides an intelligent control system for road lighting systems. Light shines on a photosensor, which converts the light signal into a voltage signal. When the voltage is above a threshold value, a stable level output is generated. When the voltage is below the threshold value, a hysteresis mechanism is used to generate a stable level output in the next cycle. This output is sent to a smart control board to control the state of the lighting lamps. This patent includes the following: an intelligent control system for a road lighting system, comprising a lighting system, a photosensor system, and a smart control board; the photosensor system and the smart control board are electrically connected.

[0004] The lighting system includes a lighting lamp and an infrared sensing module; the lighting lamp, infrared sensing module, and intelligent control board are electrically connected; the infrared sensing module detects and identifies whether a pedestrian is passing by and transmits the signal to the intelligent control board, which determines whether to activate the light sensing system based on the signal transmitted by the infrared sensing module.

[0005] The aforementioned photosensor system detects the intensity of natural light, converts it into a voltage signal, and transmits the voltage signal to the intelligent control board;

[0006] The intelligent control board controls the lighting system via an input voltage signal. When the voltage signal exceeds a set threshold, it generates a stable output level to avoid misjudgments caused by fluctuations in the ambient light threshold and momentary fluctuations (in conjunction with software delay judgment), thus achieving stable control of the lighting status. When the voltage falls below the threshold, a stable output level is generated in the next cycle through hysteresis, and the intelligent board controls the lighting status based on the output level.

[0007] Preferably, the lighting system of the intelligent control system of the road lighting system is a street lamp.

[0008] This invention solves the problem of controlling the normal operation of lighting fixtures through photoelectric detection and intelligent control when ambient brightness fluctuates within a critical range. It is particularly useful for early warning products that control lighting status by judging ambient light, avoiding misjudgments caused by fluctuations in the critical range of ambient light (such as a dim-bright state) and instantaneous fluctuations (due to software delay judgment). This achieves intelligent and stable control. Attached Figure Description

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0011] Figure 2 This is a hardware block diagram of the low-position lighting early warning system of this patent. Detailed Implementation

[0012] The present invention will be further described in detail below with reference to the embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0013] Example:

[0014] like Figure 1 , 2 As shown, the example device in this embodiment consists of a photoelectric detection intelligent control board, a lighting lamp, and an inspection port. Figure 2 This patent presents only a portion of the structure shown in the diagram, which is a complete hardware control logic diagram. The device is placed at an intersection and uses a photoelectric sensor module on the intelligent control board (see diagram). Figure 2 The main control unit connects to a light sensor to detect ambient brightness and accurately determine the surrounding light level, thus triggering the device to operate promptly when the ambient brightness falls below a certain threshold. Once operational, the infrared sensor module (infrared detection) identifies pedestrians and, through intelligent detection, links with the device's intelligent control system. Figure 2The lighting control chip on the electronic control board connects to the lighting lamp to turn on the lamp, and activates the speaker to play a safety warning voice to alert pedestrians, ensuring safety. The main function of 433 is the linkage function. Generally, at least two devices are placed at intersections. The two devices are locally linked through the buttons in the 433 module. When one device is working, the other device will work synchronously. The function of 4G is to transmit the information in the device to the cloud service through the network, facilitating real-time access and invocation. The button at the maintenance port can adjust the brightness of the lighting lamp (adjust the brightness according to the environment to prevent being too bright and dazzling and affecting pedestrians' passage), and the button on the main control board can change the working mode of the device (constant on or induction on, switching different working modes according to the on-site environment).
