Description

Technical Field

[0001] The present invention relates to the technical field of lighting control systems, and in particular to a digital intelligent lighting control system. Background Art

[0002] The development of digital intelligent lighting control systems stems from the limitations of traditional lighting systems in energy management, operational efficiency, and scenario adaptability. Early lighting control relied on manual operation or simple timers, resulting in energy waste and delayed response times. With breakthroughs in the Internet of Things (IoT), 4G / 5G communications, cloud computing, and big data technologies, lighting systems are gradually evolving towards intelligent and networked systems. For example, by integrating sensors such as photosensors and infrared sensors, the system can sense ambient light intensity and occupant activity in real time, enabling dynamic dimming and zoned control. Furthermore, wireless communication technologies (such as 4G) allow managers to remotely monitor device status and adjust lighting strategies, significantly improving response speed and management reach. At the algorithmic level, the application of adaptive control models and machine learning techniques enables the system to optimize energy consumption based on historical data, reducing operating costs. This technology has now expanded into smart cities, industrial plants, and commercial buildings, becoming a core infrastructure for achieving green and low-carbon goals.

[0003] In existing technologies, when using sensors to collect data on pedestrian flow, data collection often relies on single sensors such as photosensors and infrared sensors. When using infrared sensors, the principle is to count dynamic pedestrian flow based on the number of times infrared rays are blocked, which has the limitation of falsely inflating the count due to stationary people. When using photosensors, sudden changes in ambient lighting (such as cloud cover and vehicle light interference) can cause abnormal fluctuations in the photosensitivity value, resulting in missed detections.

[0019] The present invention provides a digital intelligent lighting control system with the following beneficial effects:

[0020] 1. The aerial infrared sensor array acquisition module counts dynamic human traffic based on the number of infrared ray obstructions. However, resident personnel can inflate the count, resulting in data collection errors. The ground-based photosensitive sensor array acquisition module identifies the number of people moving by blocking ground lights, causing a change in the resistance of the photosensors next to the lights. However, sudden changes in ambient lighting (such as cloud cover, vehicle light interference, and obstructions) can cause abnormal fluctuations in the photosensor resistance, resulting in missed detections. Collaborative monitoring of the two can achieve dual verification and reduce false positives.

[0021] 2. The dual-modal data acquisition module collects pedestrian flow data in real time and transmits it back to the data processing center, capable of generating density heat maps and predicting pedestrian flow trends. When the pedestrian flow exceeds the threshold, the module activates adjacent backup lighting areas to form an evacuation guidance path. When the pedestrian flow is below the threshold, the module turns off lighting in non-core areas to reduce power consumption.

[0022] 3. The aerial infrared sensor array acquisition module can be used to correct the data of the ground photosensor array acquisition module. Due to sudden changes in ambient light (such as cloud cover, vehicle light interference, and debris cover), the photosensitive resistance value may fluctuate abnormally, resulting in missed detection of the ground photosensor array acquisition module. At this time, the infrared receiver can take a picture of the abnormal resistance value at the ground photosensor array acquisition module and transmit it back to the data processing center. The computer will determine the cause of the abnormal resistance value and change the coefficient in the algorithm formula to correct it, thereby further improving the accuracy of pedestrian flow data collection.

[0023] 4. The backup lighting control device can manually adjust the lighting area and has a preset function, which facilitates manual control and adjustment of lighting equipment and areas when the dual-modal data acquisition module is abnormal. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] like Figure 1As shown, in this embodiment, based on the digital intelligent lighting control system, it includes:

[0035] Dual-modal data acquisition module for collecting real-time pedestrian flow data;

[0036] Data processing center 4 is used to process the pedestrian flow data collected in real time by the dual-modal data acquisition module; data processing center 4 can generate density heat maps and predict pedestrian flow trends; when the pedestrian flow exceeds the threshold, adjacent backup lighting areas are activated to form evacuation guidance paths; when the pedestrian flow is less than the threshold, lighting in non-core areas is turned off to reduce power consumption;

[0037] and lighting control devices, which are directly controlled by the data processing center and can also be manually controlled by a backup lighting control device 5;

[0038] The dual-modal data acquisition module includes an aerial infrared sensor array acquisition module 1 and a ground-based photosensitive sensor array acquisition module 2. The aerial infrared sensor array acquisition module 1 counts dynamic human flow based on the number of infrared ray obstructions, while the ground-based photosensitive sensor array acquisition module 2 identifies the number of people walking by blocking a ground lamp 23 by stepping on it, causing a change in the resistance of a photosensitive sensor 24 next to the lamp 23.

[0039] In specific implementations, the aerial infrared sensor array acquisition module 1 counts dynamic human traffic based on the number of infrared ray obstructions. However, resident personnel can lead to an inflated count, resulting in data collection errors. The ground-based photosensitive sensor array acquisition module 2 identifies the number of people walking by blocking the ground lamp 23, causing a change in the resistance of the photosensitive sensor 24 next to the ground lamp 23. However, sudden changes in ambient lighting (such as cloud cover, vehicle light interference, and obstruction by debris) can cause abnormal fluctuations in the photosensitive resistance, resulting in missed detections. The coordinated monitoring of the two can achieve double verification and reduce false positives.

[0040] As an implementation method in this embodiment, the human flow algorithm formula of the aerial infrared sensor array acquisition module 1 is as follows: ;in, , represents the blocking state of the i-th infrared ray at time t; The preset weights are adjusted according to the position of infrared rays;

[0041] The human flow algorithm formula of the ground photosensitive sensor array acquisition module 2 is as follows: ;in, , represents the resistance change of the jth photosensitive unit; , is the preset confidence level of the stampede event based on the resistance change rate;

[0042] The pedestrian flow algorithm formula of the dual-modal data acquisition module is: , where α and β are preset coefficients.

[0043] As an implementation method in this embodiment, please refer to Figure 2 The aerial infrared sensor array acquisition module 1 includes a fixing part 11, on which a plurality of infrared emitting parts 12 are provided. An infrared receiving part 13 is provided on the upper part of the infrared emitting part 12. The infrared receiving part 13 is connected to one end of a wire 3, and the other end of the wire 3 is connected to a data processing center 4; the infrared receiving part 13 detects the blocking state of the infrared rays of the infrared emitting part 12, and then transmits the data to the data processing center 4 through the wire 3, thereby achieving the technical effect of monitoring the flow of people.

[0044] In the specific implementation, the fixing part 11 is a common facility such as a fence, a sculpture, a trash can, etc., which is convenient for the installation and debugging of the infrared transmitter 12, ensuring the installation angle and installation position of the infrared transmitter 12, and further improving the monitoring accuracy of the flow of people; the infrared receiver 13 is a camera with an infrared receiving function, and the angle of the infrared receiver 13 is adjustable, which is convenient for adjusting the monitoring range of the flow of people. This technology is an existing technology and will not be disclosed in detail here.

A plurality of floor lamps 23 and a photosensitive sensor 24 are arranged in the mounting grooves 22; the photosensitive sensor 24 is connected to one end of the wire 3, and the other end of the wire 3 is connected to the data processing center 4; when pedestrians step on the ground photosensor array acquisition module 2, they will temporarily block the floor lamp 23 installed in the ground photosensor array acquisition module 2. When the floor lamp 23 is blocked, the light reflected by the soles of the pedestrians will cause the amount of light entering the photosensitive sensor 24 to increase, and the resistance value of the photosensitive sensor 24 changes, thereby reflecting the number of people walking.

[0046] In specific implementation, sudden changes in ambient light (such as cloud cover, vehicle light interference, and debris obstruction) may cause abnormal fluctuations in the photoresistance value, resulting in missed detection. At this time, the infrared receiver 13 can take a picture of the abnormal resistance value at the ground photosensitive sensor array acquisition module 2 and transmit it back to the data processing center 4. The computer will determine the cause of the abnormal resistance value and change the coefficient in the algorithm formula to correct it, thereby further improving the accuracy of pedestrian flow data collection.

The three modes of the main clamping block 63, namely mode 1, mode 2, and off mode, are adjusted by changing the position of the main clamping block 63 within the three main switch slots 51.

[0048] In a specific implementation, a total damping member 66 is provided at the contact portion between the total limit plate 65 and the total switch limit slot 53, which can enhance the damping and frustration feeling when pulling the total button 61 to drive the total card block 63 to move in the three total switch card slots 51, thereby ensuring the accuracy of the movement of the total card block 63.

[0049] As an implementation method in this embodiment, please refer to Figure 4-Figure 7 The disconnect switch 7 includes a disconnect button 71.

[0051] As an implementation method in this embodiment, please refer to Figure 4 and Figure 8The main switch 6 also includes a main switch mode indicator light 67 and a main switch mode indicator light 68, and the sub-switch 7 also includes a sub-switch indicator light 77; the circuit diagram of the main switch mode indicator light 67, the main switch mode indicator light 68 and the sub-switch indicator light 77 is as shown in FIG. Figure 8 As shown, when the main block 63 is in the mode 1 position, that is, S 总 With LED 总1 Connected, at this time the main switch mode 1 indicator light 67 and all sub-switch indicator lights 77 are lit, each sub-switch 7 is in the lit state; when the main card block 63 is in mode 2 position, that is, S 总 With LED 总2 When the main switch mode 1 indicator light 68 is connected, the main switch mode 2 indicator light 68 lights up, and each sub-switch 7 can be adjusted independently by the position of the sub-switch block 73 in the sub-switch slot 54.
