Description

Technical Field

[0001] The invention relates to the technical field of landscape lamp energy-saving control, in particular to an energy-saving control system for garden landscape lamps. Background Art

[0002] Landscape lighting refers to outdoor lighting projects that have both lighting functions and artistic decoration and beautification functions. Landscape lighting can be divided into road landscape lighting, garden landscape lighting, and architectural landscape lighting. In the field of garden landscape lighting, the existing landscape light control technology mainly relies on preset time control and simple light sensing control. Among them, the time control method usually turns on and off the landscape lights according to fixed times. Specifically, it turns on at a fixed time in the evening and turns off at a fixed time in the early morning. Simple light sensing control sets a single light threshold. When the ambient light is lower than the threshold, the landscape light is turned on, and when it is higher than the threshold, it is turned off.

[0003] In actual applications, the length of day and night is different in the four seasons. Special weather such as rainy days can cause sudden changes in the sky. The existing fixed time control cannot be adjusted according to the actual changes in ambient brightness. It is easy for the landscape lights to turn on at dawn and not turn on at dusk, which in turn causes energy waste and insufficient lighting.

[0004] In addition, existing light sensing controls can usually only turn landscape lights on and off, and cannot dynamically adjust light intensity based on real-time changes in ambient brightness and the importance of brightness to the current landscape viewing area. As a result, when ambient brightness is high, landscape lights still illuminate at a fixed high intensity, resulting in unnecessary energy consumption. When ambient brightness is low, sufficient lighting brightness cannot be provided, making it impossible to achieve precise energy-saving control, and also resulting in energy waste.

[0005] Therefore, those skilled in the art provide a garden landscape lamp energy-saving control system to solve the problems raised in the above background technology. Summary of the invention

[0006] The technical problem solved by the present invention is to provide an energy-saving control system for garden landscape lamps, so as to flexibly adapt to environmental changes, dynamically adjust light intensity, and achieve the effect of precise energy-saving strategies.

[0007] To solve the above problems, the present invention provides the following technical solutions: A garden landscape lamp energy-saving control system, comprising landscape lamps arranged in various landscape areas of the garden for lighting; A control system is installed and connected inside the landscape lamp; The control system is provided with a data acquisition module, a data processing module and a control execution module; The data acquisition module transmits the currently acquired ambient brightness in real time, the ambient brightness reference preset and stored therein, the maximum light intensity, and the viewing characteristics of the landscape area to the data processing module; The data processing module outputs determination condition information to the control execution module according to the currently acquired ambient brightness and the maximum light intensity; The control execution module controls the landscape lamp to enter a trigger mode including a sleep mode and an illumination mode according to the determination trigger condition set by the system and the determination condition information; When the landscape lamp enters the illumination mode, the data processing module obtains the real-time light intensity according to the determination condition information, the maximum light intensity, and the viewing characteristics of the landscape area; The control execution module receives the real-time light intensity and controls the landscape lamp to adjust the real-time light intensity.

[0008] Further: The maximum light intensity can be directly obtained on the product of the landscape lamp, and the maximum light intensity is entered into the data acquisition module.

[0009] Further: The data acquisition module internally includes an ambient brightness sensor and a data storage device; The ambient brightness sensor: is used for measuring the currently acquired ambient brightness of each landscape area in the garden landscape in real time and transmitting the currently acquired ambient brightness to the data processing module; The data storage device: is used for storing the maximum light intensity and the preset ambient brightness reference, as well as the operation state data of the landscape lamp formed by the acquisition and processing of the data acquisition module and the data processing module.

[0010] Further: A computing device and a judgment trigger are fixedly connected inside the data processing module; The judgment trigger: is used for judging the trigger mode triggered by the determination condition information according to the determination trigger condition, and the determination trigger condition includes yes and no; The computing device: is used for receiving the currently acquired ambient brightness, the ambient brightness reference, and the maximum light intensity; According to and by using the currently acquired ambient brightness and the ambient brightness reference, the determination condition information is obtained; When the determination trigger condition is yes, according to the determination condition information and the maximum light intensity, the preliminary light adjustment intensity is obtained. Since the determination trigger condition is yes, the determination condition information that the currently acquired ambient brightness is lower than the ambient brightness reference is obtained. Subtracting the determination condition information from the constant 1, the first adjustment intensity lower than the ambient brightness reference is obtained. Multiplying the first adjustment intensity by the maximum light intensity, the preliminary light adjustment intensity is obtained; Based on the initially adjusted light intensity, the determination condition information, and the ornamental characteristics of the landscape area, obtain the real-time light intensity for finally controlling the landscape light, that is, multiply the second adjusted intensity obtained by multiplying the determination condition information by the ornamental characteristics of the landscape area by the initially adjusted light intensity for secondary adjustment to obtain the real-time light intensity.

[0011] Furthermore: The ornamental characteristics of the landscape area are set in the range of 0 - 1 according to the importance of the lights used for viewing in each landscape area initially set in the garden. Specifically, when the light intensity required for viewing in the landscape area is low, the ornamental characteristics of the landscape area are made close to 0, and when the light intensity required for viewing in the landscape area is high, the ornamental characteristics of the landscape area are made close to 1; The specific process of triggering the trigger mode based on the determination trigger condition is as follows: When the determination trigger condition is yes, it is used for the lighting mode where the current ambient brightness is lower than or equal to the ambient brightness reference; When the determination trigger condition is no, it is used for the sleep mode where the current ambient brightness is higher than the ambient brightness reference.

[0012] Furthermore: The internal of the control execution module includes a relay control device and a dimming device; The relay control device: is used to control the landscape light to enter the trigger mode including the sleep mode and the lighting mode according to the determination trigger condition determined by the judgment trigger; The dimming device: is used to control and adjust the light intensity of the landscape light according to the real-time light intensity obtained by the calculation device.

[0013] Furthermore: The ambient brightness reference is set according to the test parameter information before the landscape light is put into use. The specific implementation steps are as follows: S1: Recruit test volunteers to conduct continuous one-week environmental perception tests in the evening and on rainy days; S2: The data acquisition module real-time collects and records the ambient brightness during the test stage when the volunteers perceive that the landscape light is needed for auxiliary lighting; S3: The data processing module receives the ambient brightness during the test stage and obtains the average value according to the number of records, that is, the ambient brightness reference.

[0014] The effects of the above solution are as follows: The present invention uses a data acquisition module to sense the current ambient brightness in real time, and combines it with the maximum light intensity and ambient brightness benchmark stored therein. First, it determines the triggering conditions for the landscape lights. Among them, when the current ambient brightness drops below the ambient brightness benchmark, the landscape lights are automatically turned on, and when it exceeds the ambient brightness benchmark, the landscape lights are turned off. Such a setting enables the system to flexibly control the turning on and off of the landscape lights according to the actual ambient brightness, regardless of the changes in the day-night duration in different seasons or the special weather such as rainy or cloudy days, and improves the accuracy of lighting and the energy-saving effect.

[0015] After the landscape lights are turned on, based on the magnitude of the determination condition information and the viewing characteristics of the landscape area, the preliminary adjusted light intensity and the real-time light intensity of the landscape lights are respectively obtained. This dynamic adjustment mechanism can accurately adjust the light intensity of the landscape lights according to the real-time changes in the ambient brightness and the importance of the lights required for viewing in the landscape area, achieving precise energy-saving control. In this way, according to the subtle changes in the ambient brightness and the different viewing requirements of the landscape area, the working state and light intensity of the landscape lights can be adjusted in a timely manner, and energy waste can be minimized to improve the energy utilization efficiency.

[0016] Figure 1 is a schematic diagram of the overall structure of the energy-saving control system for this garden landscape light; Figure 2 is a schematic diagram of the step flow for setting the test parameter information in the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely introduced in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] Embodiment 1, please refer to Figure 1 and Figure 2 , an energy-saving control system for a garden landscape light, including landscape lights arranged in each landscape area of the garden for lighting; A control system is installed and connected inside the landscape light; A data acquisition module, a data processing module, and a control execution module are arranged inside the control system; The data acquisition module transmits the currently collected ambient brightness, the pre-set and stored ambient brightness benchmark, the maximum light intensity, and the viewing characteristics of the landscape area to the data processing module; The data processing module outputs determination condition information to the control execution module according to the current ambient brightness and the maximum light intensity; The control execution module controls the landscape light to enter a trigger mode including a sleep mode and a lighting mode according to the determination trigger conditions set by the system and the determination condition information; When the landscape lamp enters the lighting mode, the data processing module obtains the real-time illumination intensity according to the determination condition information, the maximum illumination intensity, and the viewing characteristics of the landscape area. The control execution module receives the real-time illumination intensity and controls the landscape lamp to adjust the real-time illumination intensity. Since the maximum illumination intensity can be directly obtained on the product of the landscape lamp and is entered into the data acquisition module, the maximum illumination intensity can be directly used in the energy-saving control of the garden landscape lamp for calculation to assist in the energy-saving adjustment of the illumination intensity. Different specifications of landscape lamps have different maximum illumination intensities. When installing the landscape lamp, the product manual of the landscape lamp can also be referred to to select the maximum illumination intensity required for the current garden landscape. The data acquisition module internally includes an ambient light sensor and a data storage device. Ambient light sensor: It is used to measure the current ambient brightness of each landscape area in the garden landscape in real time and transmit the current ambient brightness to the data processing module. Data storage device: It is used to store the maximum illumination intensity, the preset ambient brightness reference, and the operation status data of the landscape lamp formed by the acquisition and processing of the data acquisition module and the data processing module. Among them, it is worth noting that the ambient light sensor, as a part of the data acquisition module, is used to measure the current ambient brightness of each landscape area in the garden landscape in real time. It converts the analog signal collected through serial communication into a digital signal and then transmits it to the data processing module. The characteristics of strong anti-interference ability and long transmission distance of serial communication are suitable for use in outdoor environments such as gardens. The data storage device stores information such as the maximum illumination intensity, the ambient brightness reference, and the operation status data of the landscape lamp. The data storage device and the data processing module are connected by Ethernet. The control execution module internally includes a relay control device and a dimming device. Relay control device: It is used to control the landscape lamp to enter the trigger mode including the sleep mode and the lighting mode according to the determination trigger condition determined by the judgment trigger. Dimming device: It is used to control and adjust the illumination intensity of the landscape lamp according to the real-time illumination intensity obtained by the calculation device.

[0019] In this embodiment, by means of the ambient light sensor to collect the current ambient brightness and the data processing module to calculate the determination condition, the control execution module can flexibly control the startup and shutdown of the landscape lamp according to the actual environment, avoiding energy waste.

[0020] Subsequently, using the size of the determination condition information and the maximum light intensity stored in the data storage unit, the preliminary light adjustment intensity is obtained, enabling reasonable dimming when the landscape light is started and improving energy utilization efficiency.

[0021] Finally, further combining the real-time current ambient brightness and the viewing characteristics of the landscape area, the real-time light intensity is dynamically and precisely adjusted through the dimming device, so that the entire system can achieve efficient energy-saving lighting under the coordination of the data acquisition module, the data processing module, and the control execution module. Among them, the ambient brightness benchmark conforms to the human eye visual characteristics and can optimize the energy-saving effect.

[0022] In addition, according to the landscape light determination condition information and the specific determination direction of the determination trigger condition, the control execution module controls the start and stop of the landscape light through the relay control device. When the landscape light enters the lighting mode, the relay closes and the landscape light turns on. When the landscape light enters the sleep mode, the relay opens and the landscape light turns off. The control system adjusts the light intensity of the landscape light through the dimming device according to the calculated real-time light intensity of the landscape light. The dimming device can adopt pulse width modulation technology to convert the control signal into appropriate voltage and current, thereby achieving precise adjustment of the landscape light intensity.

[0023] Please refer to Figure 1 and Figure 2 , a computing device and a judgment trigger are fixedly connected inside the data processing module; The judgment trigger: is used to determine the trigger mode triggered by the determination condition information according to the determination trigger condition, and the determination trigger condition includes yes and no; The computing device: is used to receive the current ambient brightness, the ambient brightness benchmark, and the maximum light intensity; According to and using the current ambient brightness and the ambient brightness benchmark, the determination condition information is obtained; When the determination trigger condition is yes, according to the determination condition information and the maximum light intensity, the preliminary light adjustment intensity is obtained; According to the preliminary light adjustment intensity, the determination condition information, and the viewing characteristics of the landscape area, the real-time light intensity for finally controlling the landscape light is obtained; Among them, it should be noted that the judgment trigger in the data processing module determines and triggers the start and stop of the landscape light according to the determination condition obtained by the computing device, and it transmits digital signals to the relay control device in the control execution module through the GPIO interface.

[0024] The relay control device controls the landscape lights to enter the sleep mode or the lighting mode according to these signals. After the computing device in the data processing module calculates the real-time illumination intensity of the landscape lights, the corresponding control signals are transmitted to the dimming device in the control execution module through the pulse width modulation interface.

[0025] The PWM signal can accurately control the voltage / current output by the dimming device, thereby achieving precise adjustment of the illumination intensity of the landscape lights. In addition, the specific triggering mode triggered based on the determined trigger condition is as follows: When the determined trigger condition is yes, it is used for the lighting mode where the current ambient brightness is lower than and equal to the ambient brightness reference. When the determined trigger condition is no, it is used for the sleep mode where the current ambient brightness is higher than the ambient brightness reference.

[0026] The calculation formulas calculated using the computing device are as follows: ; ; ; Where: QP is the determination condition for judging whether to start the landscape lights; L is the current ambient brightness of each landscape area in the garden landscape measured in real time by the ambient brightness sensor; L0 is the ambient brightness reference preset and stored in the data acquisition module; LQ1 is the preliminary adjusted illumination intensity adjusted according to the determination condition and the maximum illumination intensity; LQ max is the maximum illumination intensity preset and stored in the data acquisition module; LQ2 is the real-time illumination intensity of the landscape lights controlled by the control execution module through signal reception and processing; g is the landscape area viewing feature of the current landscape area preset and stored in the data acquisition module.

[0027] In this embodiment, first, when the determined trigger condition is yes, it indicates that the current ambient brightness is lower than and equal to the ambient brightness reference, that is, L ≤ L0, which also means that the current natural light is not sufficient to support viewing in the garden. When the determined trigger condition is no, it indicates that the current ambient brightness is greater than the ambient brightness reference, that is, L > L0, which also means that the current natural light is sufficient to support viewing in the garden. And the reference value is set to 1 because when the current ambient brightness is equal to the ambient brightness reference, that is, L = L0, the determination result is exactly 1, thus forming a direct trigger mechanism for convenient trigger control of the landscape lights.

[0028] It should be noted that combines the determination condition QP for judging whether to start the landscape light and the maximum light intensity LQ preset in the data acquisition module max to calculate the preliminary light intensity adjustment LQ1.

[0029] When L is close to L0, the landscape light does not need to provide too high a light intensity, and LQ1 decreases accordingly. When L is much lower than L0, the landscape light needs to provide a higher light intensity, and LQ1 increases accordingly. In this way, the light intensity can be reasonably adjusted according to the ambient brightness when the landscape light is started, avoiding waste of energy. Among them, the maximum light intensity LQ of the landscape light is considered max This actual parameter makes the calculated preliminary light intensity adjustment LQ1 neither exceed the maximum capacity of the lamp nor fail to meet the basic lighting requirements under different ambient brightnesses.

[0030] Adding a square root operation in makes the adjustment of the light intensity smoother, avoiding large fluctuations in the landscape light intensity when the ambient brightness changes slightly. This is because the human eye's perception of light intensity is not linear, and the square root operation is more in line with the human eye's visual characteristics and can provide a more comfortable lighting experience. If QP is directly used to adjust the light intensity, then when the ambient brightness changes slightly, the light intensity of the landscape light will fluctuate greatly, resulting in unstable lighting effects and discomfort to the human eye. In addition, the viewing feature g of the landscape area is set to take values in the range of 0-1 according to the importance of the lights used for viewing in each landscape area initially set in the garden. Specifically, when the light intensity required for viewing in the landscape area is low, the viewing feature of the landscape area is made close to 0, and when the light intensity required for viewing in the landscape area is high, the viewing feature of the landscape area is made close to 1; After adding a square root operation to the real-time light intensity LQ1, the growth and decay rates of the function will slow down, making the adjustment of the light intensity smoother. Specifically: When the ambient brightness slowly increases, using the square root operation can avoid a sharp drop in the light intensity of the landscape light, but rather decrease at a relatively gentle speed, making the change in the lighting effect more natural. The human eye's perception of light intensity is not linear, but closer to a logarithmic relationship. The square root function can, to a certain extent, simulate the human eye's perception characteristics of light changes; When the change in the ambient brightness is small, the human eye is less sensitive to the change in light intensity, while when the change in the ambient brightness is large, the human eye is more sensitive to the change in light intensity. Through the square root operation, the adjustment of the light intensity of the landscape light can be matched with the human eye's visual characteristics, providing a more comfortable lighting experience while ensuring energy conservation; In the evening of actual application, after the landscape lights are turned on, if the sky clouds disperse and the sky gradually brightens, the current ambient brightness L will increase, and the value of the determination condition QP will increase. The value of will also increase, but due to the effect of the square root operation, the increase amplitude is relatively small. At this time, the real-time illumination intensity LQ2 of the landscape lights will decrease at an appropriate speed to adapt to the change of the ambient brightness, avoid over-illumination, and thus achieve the purpose of energy conservation. Therefore, multiplying the determination condition QP under the square root and the preliminary illumination adjustment intensity LQ1 can dynamically adjust the real-time illumination intensity LQ2 of the landscape lights. After the landscape lights are turned on, with the real-time change of the ambient brightness, the illumination intensity can be accurately adjusted to minimize energy waste and achieve the purpose of energy conservation.

[0031] Example two, please refer to Figure 2 , the ambient brightness benchmark is set according to the test parameter information before the landscape lights are put into use. The specific implementation steps are as follows: S1: Recruit test volunteers to conduct continuous one-week environmental perception tests in the evening and on rainy and cloudy days respectively; S2: The data acquisition module real-time collects and records the ambient brightness during the test stage when the volunteers perceive that the environment needs landscape lights for auxiliary lighting; S3: The data processing module receives the ambient brightness during the test stage and calculates the average value based on the number of records, which is the ambient brightness benchmark; The specific calculation formula is as follows: ; Among them: N is the number of records of the need for landscape lights for auxiliary lighting during the continuous one-week environmental perception test, and L0 i is the ambient brightness during the test stage of the need for landscape lights for auxiliary lighting recorded during the continuous one-week environmental perception test; In this embodiment, recruiting test volunteers to conduct continuous one-week environmental perception tests in the evening and on rainy and cloudy days respectively is because these time periods and weather conditions cover the typical scenarios that the garden landscape lights will face and can simulate different ambient brightness situations that the landscape lights will encounter in actual use; And taking the moment when the volunteers perceive that the environment needs landscape lights for auxiliary lighting as the data collection point fully considers the actual visual needs of people. The set ambient brightness benchmark is more in line with people's expectations for lighting when moving in the garden and can ensure that the landscape lights are turned on in time when lighting is really needed.

[0032] In addition, a one-week continuous test was conducted and data were recorded, ensuring a sufficient sample size. By recording the environmental brightness during the test phase when volunteers perceived the need for landscape lighting assistance multiple times, the data became more representative and reliable. The data processing module received the environmental brightness during the test phase and obtained the average value as the environmental brightness benchmark based on the number of records. This statistical method can effectively reduce the influence of individual abnormal data and make the environmental brightness benchmark better reflect the reasonable lighting requirements under general circumstances.

[0033] Thus, the landscape lighting control system can more accurately determine when to turn on and off the landscape lights. When the environmental brightness drops below this benchmark, it controls the landscape lights to enter the lighting mode, and when it exceeds the benchmark, it controls the landscape lights to enter the sleep mode, avoiding the situations of lights still being on at dawn and lights not being on at dusk that may occur in traditional control methods, improving the energy utilization efficiency and reducing energy waste.

[0034] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be subject to the scope defined by the claims.
