Description

Technical Field

[0001] The present disclosure relates to the technical field of intelligent lighting, and particularly to an intelligent lighting system. Background Art

[0002] A lighting system is a comprehensive device composed of light sources, luminaires, control devices, and supporting electrical and electronic components, aiming to provide a suitable lighting environment for places such as factory areas and campuses.

[0003] Traditional lighting systems usually rely on manual control, using a unified switching method to turn on or off the lights, and the brightness of the lights is fixed. This design is particularly likely to cause visual fatigue in indoor environments and may even damage eyesight. For outdoor lighting, due to the lack of intelligent control, the lights often remain on when there is no one, which not only causes energy waste but also is not conducive to environmental protection.

[0004] To solve this problem, people have started to adopt voice-controlled lighting systems, which automatically turn on or off the lighting by detecting sound signals of a certain intensity. Although this method can achieve the effect of turning off the lights when people leave to a certain extent and reduce energy waste, its judgment conditions are relatively single and are easily affected by misjudgment. For example, when there is non-human noise on-site, the lighting system may also be wrongly activated, resulting in unnecessary energy consumption.

[0005] Therefore, existing lighting systems face challenges such as energy waste, visual fatigue, misjudgment activation, and the inability to meet personalized lighting needs. Summary of the Utility Model

Detailed implementation manners

[0028] The following will further describe in detail the implementation manners of the present disclosure in conjunction with the accompanying drawings and embodiments. The detailed description and the accompanying drawings of the following embodiments are used to exemplarily illustrate the principles of the present disclosure, but cannot be used to limit the scope of the present disclosure. The present disclosure can be implemented in many different forms, not limited to the specific embodiments disclosed herein, but including all technical solutions falling within the scope of the claims.

[0029] These embodiments are provided by the present disclosure to make the present disclosure thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, the compositions of materials, numerical expressions, and numerical values set forth in these embodiments should be construed as merely exemplary, rather than as limitations.

[0030] Term Explanation:

[0031] The PLC controller, whose full name is Programmable Logic Controller, is a digital operating electronic system used for various types of machinery and production processes in automated control.

[0032] The HMI (Human-Machine Interface) human-machine interface refers to the interface for information interaction and communication between humans and machines.

[0033] Figure 1 It is a schematic structural diagram disclosed in the first embodiment of the intelligent lighting system of the present disclosure, as Figure 1 shown. The intelligent lighting system may include: a lighting module 1, a sensing module 2, a signal amplifier 3, and a PLC controller 4.

[0034] Among them, the sensing module 2 and the lighting module 1 are located in the same installation area; the input end of the signal amplifier 3 is connected to the output end of the sensing module 2 for enhancing the signal collected by the sensing module 2; the input end of the PLC controller is connected to the output end of the signal amplifier 3, and the output end of the PLC controller 4 is connected to the input end of the lighting module 1 for controlling the lighting module 1 according to the signal enhanced by the signal amplifier 3.

[0035] It should be noted that since the signal acquisition of the sensing module has a certain error range, directly using this signal is extremely likely to cause misjudgment in automatic control. Therefore, it is necessary to cooperate with a signal amplifier to filter and analyze this signal, making the collected signal more accurate, so as to avoid misjudgment activation.

[0036] For example, when the sensor detects human movement or other triggering conditions, it will send a signal to the PLC controller. If the distance between the sensor and the controller is far, or the signal is interfered during transmission, the signal amplifier can ensure that the signal is still clear and accurate when it reaches the controller, thus ensuring the response speed and reliability of the control system.

[0037] In some embodiments, the lighting module 1 may include one or more lamp groups, and the connection mode between one or more lamp groups is parallel.

[0038] In some embodiments, the sensing module 2 can be located in the same installation area as the lighting module 1 through the first layout and / or the second layout. Among them, the first layout can be integrated on the lighting module 1, and the second layout can be independently arranged in the installation area where the lighting module 1 is located.

[0039] Specifically, if it is outdoors, the sensing module can be integrated on the lighting module; if it is indoors, the lighting module can be installed on the ceiling indoors, and the sensing module can be installed on the wall indoors.

[0040] It should be noted that in an outdoor scenario, the lighting module can be a street lamp, which is usually arranged at intervals. Therefore, the sensing module can be integrated on the street lamp, so that in a night environment, when a pedestrian walks into the lighting range of the street lamp, the sensing module senses the pedestrian signal and the street lamp automatically lights up. In an indoor scenario, the lighting module can be an LED lamp, which is usually set up a lamp group in an area, and the range of a sensing module is limited. Therefore, the sensing module can be installed at multiple places on the indoor wall to achieve precise sensing.

[0041] In some embodiments, referring to Figure 2 As shown, the sensing module 2 includes an infrared sensor 21 and a photosensitive element 22. Among them, the infrared sensor 21 is used to collect the infrared induction signal in the installation area, and the photosensitive element 22 is used to collect the ambient light signal in the installation area.

[0042] It can be understood that when the infrared sensor obtains the infrared induction signal and the ambient light signal collected by the photosensitive element is lower than a certain threshold, it indicates that the ambient light in this area is relatively dark and there are pedestrians, so the light needs to be turned on for lighting.

[0043] In a feasible implementation manner, the sensing module 2 is located in the same installation area as the lighting module 1 through the first layout. For example, the lighting module 1 is arranged at the upper part of the installation area, and both the infrared sensor 21 and the photosensitive element 22 are integrated on the lighting module 1.

[0044] In another feasible implementation manner, the sensing module 2 is located in the same installation area as the lighting module 1 through the second layout. For example, the lighting module 1 and the photosensitive element 22 are arranged side by side at the upper part of the installation area, and multiple infrared sensors 21 are arranged at intervals around the installation area.

[0045] It should be noted that in a scenario where multiple infrared sensors are installed, when there are many pedestrians in the area, due to the intervals and shadows between pedestrians blocking some light, the brightness can be automatically increased according to the number of infrared sensors that obtain induction signals at the current moment to ensure clear vision and enhance safety. When there are few pedestrians in the area, that is, only a few or a single infrared sensor is triggered at the current moment, the brightness can be automatically decreased to save energy and maintain a suitable lighting environment.

[0046] In some embodiments, when the infrared sensor does not obtain an infrared induction signal or the ambient light signal obtained by the photosensitive element is greater than a certain threshold, the lighting device can be controlled to be turned off within a certain time or maintained in the off state.

[0047] The intelligent lighting system provided by the embodiments of the present disclosure can automatically control the startup and shutdown of the lighting device according to the induction signal. At the same time, in a scenario where multiple infrared sensors are installed, it can intelligently adjust the lighting brightness according to the actual pedestrian flow density and activity conditions, avoid resource waste, and meet the personalized lighting needs of users.

[0048] Figure 3 It is a schematic structural diagram disclosed in the second embodiment of the intelligent lighting system of the present disclosure. As Figure 3 shown, the intelligent lighting system may include: a lighting module 1, a sensing module 2, a signal amplifier 3, and a PLC controller 4, and a brightness adjustment module 5 is provided between the PLC controller 4 and the lighting module 1. The brightness adjustment module 5 is used to control the brightness intensity of the lighting module 1.

[0049] In some embodiments, referring to Figure 4 shown, the brightness adjustment module 5 includes a first brightness module 51, a second brightness module 52, a third brightness module 53, and a fourth brightness module 54.

[0050] Among them, the first brightness module 51 is used to turn on and make the brightness intensity of the lighting module 1 below 30%, the second brightness module 52 is used to turn on and make the brightness intensity of the lighting module 1 below 70%, the third brightness module 53 is used to turn on and make the brightness intensity of the lighting module 1 below 100%, and the fourth brightness module 54 is used to turn off and make the brightness intensity of the lighting module 1 0%.

[0051] The intelligent lighting system provided by the embodiments of the present disclosure can, through the fine control of the brightness adjustment module 5, intelligently adjust the brightness of the lighting module 1 according to actual needs and environmental changes to achieve a more energy-saving and comfortable lighting effect.

[0052] Figure 5 It is a schematic structural diagram disclosed in the third embodiment of the intelligent lighting system of the present disclosure. As Figure 5As shown in the figure, the intelligent lighting system may include: a lighting module 1, a sensing module 2, a signal amplifier 3, a PLC controller 4, and a manual control module 6.

[0053] Among them, the manual control module 6 is connected to the PLC controller 4 and is used to manually control the turning on or off of the lighting module 1.

[0054] The intelligent lighting system provided by the embodiments of the present disclosure realizes the flexibility and convenience of lighting control by combining automatic sensing technology and a manual control module. The manual control module 6 provides users with an option to directly control the lighting, enabling users to manually turn on or off the lighting module 1 according to the needs and preferences of the current scenario.

[0055] Figure 6 is a schematic structural diagram disclosed in Embodiment 4 of the intelligent lighting system of the present disclosure. As Figure 6 shown in the figure, the intelligent lighting system may include: a lighting module 1, a sensing module 2, a signal amplifier 3, a PLC controller 4, a monitoring module 7, and a display module 8.

[0056] Among them, the monitoring module 7 is connected to the PLC controller 4 and the lighting module 1, and is used to obtain the on / off state and fault information of the lighting module 1 and upload them to the PLC controller 4.

[0057] In some embodiments, the display module 8 is connected to the PLC controller 4 and is used to display the on / off state and fault information of the lighting module 1.

[0058] The PLC controller 4 cooperates with the monitoring module 7, which can not only batch control lighting devices, but also monitor the operation status of each lighting lamp in real time. Without increasing the workload of management personnel, it realizes intelligent adjustment control under the condition of meeting the lighting needs of personnel in a certain area.

[0059] The intelligent lighting system provided by the embodiments of the present disclosure enhances the monitoring and user interaction capabilities of the system by integrating the monitoring module 7 and the display module 8. The design of this system makes lighting control not only intelligent, but also more transparent and easy to manage.

[0060] Figure 7 is a schematic structural diagram disclosed in Embodiment 5 of the intelligent lighting system of the present disclosure. As Figure 7 shown in the figure, the intelligent lighting system is composed of a lamp group, a PLC controller, an infrared sensor, a photosensitive element, a lamp group integrated controller, a lamp group status monitoring module, a manual controller, and an HMI human-machine interaction controller, and realizes the function of automatically adjusting the light brightness and on / off of lighting devices in the area according to the actual density of personnel.

[0061] The following specifically describes the implementation process of the intelligent lighting system of the present disclosure.

[0062] In the embodiments of the present disclosure, first, according to the acquisition of external input signals (infrared sensors, photosensitive elements), they are transmitted to a signal amplifier for processing. Then the signals are transmitted to a PLC controller, and through data analysis, some interference signals are filtered out to avoid misjudgment of the PLC control logic caused by errors. Based on the processed signals collected, the density of people in the area (effective infrared induction signals) and the external light intensity of the area (the photosensitive element collects the light intensity of non-LED light sources outside) are judged, so as to determine whether to turn on the lighting equipment and match the light intensity (adjust the lighting equipment gear). Furthermore, automatic control of starting appropriate light in different scenarios is realized.

[0063] In addition, the intelligent lighting system of the present disclosure has a real-time feedback function. The lamp group status monitoring module can monitor the real-time operation of each lamp group. When the lamp group controller starts to control the lamp group, the lamp group status monitoring module will simultaneously receive the operation feedback signal of the lamp group.

[0064] If the control signal is inconsistent with the feedback signal, it indicates that there is a fault in the lamp group in this area. The PLC automatic control system can mark the feedback signals of different area lamp groups, and then through internal signal processing and calculation, the alarm information can be displayed on the monitoring display screen (HMI human-machine interaction controller) in real time for maintenance personnel to process and repair in time.

[0065] At the same time, the intelligent lighting system provided by the embodiments of the present disclosure also has manual control, which can forcibly control the on and off of all lighting equipment, ignoring any input signal control.

[0066] The intelligent lighting system provided by the embodiments of the present disclosure can realize functions such as turning off the lights when people leave under ordinary lighting conditions (the program can add a custom delay function for turning off the lights), proper matching of lighting brightness, manual forced control of on and off, and real-time feedback of the operating status of lighting equipment, meeting the personalized needs of users.
