Description

Technical Field

[0001] The present application relates to the technical field of energy-saving lighting equipment control, and more specifically, to an energy-saving lighting equipment and method for a smart sheep house. Background Art

[0002] With the popularization of energy-saving and environmental protection concepts, energy-saving lighting equipment control has been widely used. This control technology uses intelligent sensors, the Internet of Things and automated control systems to achieve precise control of lighting equipment to reduce energy consumption and reduce operating costs. In agricultural production, traditional lighting equipment has high energy consumption and low light efficiency, and it is difficult to meet the needs of energy conservation, emission reduction and precise lighting. Therefore, in the application of new agricultural technologies such as smart sheep houses, energy-saving lighting equipment control technology is particularly important. It can automatically adjust the lighting according to the environmental parameters in the sheep house to ensure the healthy growth of the sheep in a suitable lighting environment.

[0003] In the existing energy-saving lighting equipment control, the control of energy-saving lighting equipment aims at efficiently utilizing light energy and reducing energy consumption. It adopts a variety of technical means to work together. Through light source regulation, the brightness of the light source is dynamically adjusted according to the ambient light intensity or demand. Timing control is used to realize the timed start and stop of lighting equipment. Area division control is adopted to independently adjust the light source or reflective equipment for different areas to achieve precise lighting. However, in order to realize the intelligent control layout of smart sheep houses, it is usually necessary to consider a more complex spatial layout. It is difficult for traditional direct light sources to evenly cover the target area, resulting in uneven light distribution in the target illumination area (that is, some areas are too bright, and other areas are too dark), thereby reducing the illumination effectiveness of energy-saving lighting equipment. Therefore, how to accurately guide the light in the target lighting area with complex spatial layout, so as to improve the illumination effectiveness of energy-saving lighting equipment has become a difficult problem faced by the industry.

DETAILED DESCRIPTION

[0018] In order to better understand the technical solution of the present application, the technical solution of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] refer to Figure 1, which is an exemplary flow chart of a lighting control method according to some embodiments of the present application. The lighting control method 100 is used to control the lighting of an energy-saving lighting device set in a smart sheep house. The energy-saving lighting device includes a plurality of movable reflectors. The method mainly includes the following steps: In step 101, a main reflector and an auxiliary reflector for illuminating the target lighting area in an energy-saving lighting device are determined according to the position information of the target lighting area in the smart sheep house.

[0020] In this application, the target lighting area refers to the area in the smart sheep house that needs to be illuminated. In specific implementation, the target lighting area can be, for example, a semi-enclosed sheep house area. In the smart sheep house, the environment of the sheep house is intelligently adjusted through automatic control of fans, lights, sprinklers, outdoor shading and other equipment. Special lighting control is required for semi-enclosed sheep houses to adapt to the activities and rest needs of the flock, so as to achieve the most suitable and healthiest growth environment.

[0021] It should be noted that the smart sheep house in this application refers to a new breeding model that uses modern scientific and technological means to integrate informatization, automation, and intelligence into the design and management of sheep houses. Relying on cutting-edge technologies such as the Internet of Things, artificial intelligence, and big data, it provides ranchers with refined management tools and significantly improves breeding efficiency and quality.

[0022] It should also be noted that the reference Figure 2 , this figure is a schematic diagram of the structure of the reflector in the energy-saving lighting device, the reflector structure schematic diagram includes a reflector on the inner backlight surface and a reflector on the outer light-receiving surface, wherein the main reflector is in the reflector on the outer light-receiving surface, and the auxiliary reflector is in the reflector on the inner light-receiving surface. When irradiating the target irradiation area, it is mainly achieved through the cooperation of the main reflector and the auxiliary reflector.

[0023] The reflector in the energy-saving lighting device in the present application includes a backlight reflector and a light-receiving surface reflector. The backlight reflector refers to a reflector whose light-receiving surface faces away from the irradiation direction of the light source component in the energy-saving lighting device, and the light-receiving surface reflector refers to a reflector whose light-receiving surface faces the irradiation direction of the light source component in the energy-saving lighting device.

[0024] In some embodiments, the following steps may be used to determine the main reflector and the auxiliary reflector in the energy-saving lighting device for illuminating the target lighting area according to the position information of the target lighting area in the smart sheep house, namely: Acquire the orientation information of the target lighting area and the center position point of the light source component in the energy-saving lighting device; Connecting the center position point of the target lighting area in the orientation information with the center position point of the light source component in the energy-saving lighting device to obtain an illumination reference line of the target lighting area; marking a plurality of candidate reflectors in the energy-saving lighting device based on the illumination reference line; Identify the candidate reflector with the light receiving surface closest to the light source component from all the candidate reflectors as the main reflector for illuminating the target lighting area in the energy-saving lighting device; A backlight surface candidate reflector closest to the light source component is identified from all candidate reflectors as an auxiliary reflector for illuminating a target illumination area in the energy-saving lighting device.

[0025] In a specific implementation, the position information of the target lighting area and the center position point of the light source component in the energy-saving lighting device are obtained through a camera, and the position information includes the center position point and the direction angle of the target lighting area.

[0026] It should be noted that the illumination reference line in this embodiment represents a reference line for determining the incident path of the light source component of the lighting device. This reference line can help the system accurately control the distribution of light and ensure that specific areas in the sheep house receive appropriate lighting.

[0027] In some embodiments, the following steps may be specifically adopted to mark multiple candidate reflectors in the energy-saving lighting device based on the illumination reference line, namely: Calculating the vertical distance from each reflector in the energy-saving lighting device to the illumination reference line; For each reflector, the vertical distance corresponding to the reflector is compared with a vertical distance threshold, reflectors whose vertical distances are less than the vertical distance threshold are extracted, and the extracted reflectors are used as candidate reflectors in the energy-saving lighting device, thereby obtaining multiple candidate reflectors in the energy-saving lighting device.

[0028] In a specific implementation, first, the vertical distance from each reflector in the energy-saving lighting device to the illumination reference line is calculated by Euclidean distance; secondly, for each reflector, the vertical distance corresponding to the reflector is compared with a vertical distance threshold, and the reflectors whose vertical distances are less than the vertical distance threshold are extracted; finally, the extracted reflectors are used as candidate reflectors in the energy-saving lighting device, and then multiple candidate reflectors in the energy-saving lighting device are obtained. It should be noted that, in this embodiment, the vertical distance threshold represents a pre-set standard vertical distance for screening out candidate reflectors, which can be set specifically according to actual needs and is not limited here.

[0029] In a specific implementation, a light-receiving surface candidate reflector that is closest to the light source component is identified from all candidate reflectors as the main reflector for illuminating the target lighting area in the energy-saving lighting device, that is, all light-receiving surface candidate reflectors are screened from all candidate reflectors, the center distance from each light-receiving surface candidate reflector to the light source component is calculated, the light-receiving surface candidate reflector corresponding to the smallest center distance is extracted, and the extracted light-receiving surface candidate reflector is used as the main reflector for illuminating the target lighting area in the energy-saving lighting device.

[0030] It should be noted that the main reflector in the present application refers to a main reflector that reflects light. By determining the main reflector, the light emitted by the light source can be effectively collected and reflected to accurately illuminate the target lighting area.

[0031] In a specific implementation, a backlight candidate reflector that is closest to the light source component is identified from all candidate reflectors as an auxiliary reflector for illuminating a target lighting area in the energy-saving lighting device, that is, all backlight candidate reflectors are screened from all candidate reflectors, the center distance from each backlight candidate reflector to the light source component is calculated, the backlight candidate reflector corresponding to the smallest center distance is extracted, and the extracted backlight candidate reflector is used as an auxiliary reflector for illuminating the target lighting area in the energy-saving lighting device.

[0032] It should be noted that the auxiliary reflector in the present application refers to a reflector that assists the main reflector in reflecting light. By determining the auxiliary reflector, the light emitted by the light source can be collected and reflected more accurately to accurately illuminate the target lighting area. By determining the main reflector and the auxiliary reflector, control conditions can be provided for accurately controlling the direction and energy distribution of the light.

[0033] In step 102, the lateral distance and vertical distance between the light source component and the main reflector in the energy-saving lighting device are determined, an illumination path of the light source component is constructed through the lateral distance and the vertical distance, and a first deflection angle of the main reflector in the energy-saving lighting device is determined according to the illumination path and the initial posture characteristics of the main reflector.

[0034] In some embodiments, the lateral distance and vertical distance between the light source component and the main reflector in the energy-saving lighting device may be determined by the following steps, namely: Obtaining the center position coordinates of the light source component in the energy-saving lighting device and the center position coordinates of the main reflector; Determine the lateral distance between the light source component and the main reflector in the energy-saving lighting device according to the horizontal coordinate value in the center position coordinate of the light source component and the horizontal coordinate value in the center position coordinate of the main reflector; The vertical distance between the light source component and the main reflector in the energy-saving lighting device is determined according to the vertical coordinate value in the center position coordinate of the light source component and the vertical coordinate value in the center position coordinate of the main reflector.

[0035] In a specific implementation, first, the center position coordinates of the light source component in the energy-saving lighting device and the center position coordinates of the main reflector are obtained; then, the absolute difference between the horizontal coordinate value in the center position coordinates of the light source component and the horizontal coordinate value in the center position coordinates of the main reflector is calculated, and the calculated absolute difference is used as the lateral distance between the light source component in the energy-saving lighting device and the main reflector; finally, the absolute difference between the vertical coordinate value in the center position coordinates of the light source component and the vertical coordinate value in the center position coordinates of the main reflector is calculated, and the calculated absolute difference is used as the vertical distance between the light source component in the energy-saving lighting device and the main reflector. In addition, in other embodiments, other calculation methods can be used to calculate the lateral distance and vertical distance between the light source component in the energy-saving lighting device and the main reflector, which are not limited here.

[0036] It should be noted that the lateral distance described in the present embodiment represents the distance between the light source component and the main reflector in the horizontal direction; the vertical distance described in the present embodiment represents the distance between the light source component and the main reflector in the vertical direction. By determining the lateral distance and the vertical distance, the distribution and illumination area of ​​light can be accurately controlled, the lighting efficiency and uniformity can be improved, and it can be ensured that the target lighting area obtains the appropriate light intensity, which helps to avoid light waste and uneven lighting problems.

[0037] In some embodiments, the irradiation path of the light source component is constructed by using the lateral distance and the vertical distance by specifically adopting the following steps, namely: Get the preset path planning function; The lateral distance and the vertical distance are input as input parameters into the path planning function, and the path planning function outputs the irradiation path of the light source component.

[0038] In specific implementation, first, a preset path planning function can be obtained through the illumination control database of the energy-saving lighting equipment in the smart sheep house. The path planning function is: the result of the path planning function is equal to the arithmetic square root of the sum of the squares of the two input parameter values. In this embodiment, the path planning function represents a function for planning the lighting path, which can be pre-stored in the illumination control database of the energy-saving lighting equipment in the smart sheep house; then, the lateral distance and the vertical distance are input as input parameters into the path planning function, and the output result of the path planning function is used as the illumination path of the light source component. In addition, in other embodiments, other calculation methods can be used to calculate the illumination path of the light source component, which is not limited here.

[0039] It should be noted that the illumination control database of the energy-saving lighting equipment in the intelligent sheep house in this embodiment refers to a system for storing and managing data related to lighting control. The illumination path of the light source component in this application represents the path of light propagation to the surface of the target object, that is, the propagation path of the light emitted by the light source component. By determining the illumination path, it can be ensured that the light is directly irradiated to the area that needs to be illuminated, thereby reducing light waste, improving lighting efficiency, and achieving energy saving.

[0040] In some embodiments, reference Figure 3 As shown in FIG. 1 , this figure is an exemplary flow chart of determining the first deflection angle according to some embodiments of the present application. In this embodiment, the first deflection angle of the main reflector in the energy-saving lighting device is determined according to the illumination path and the initial posture characteristics of the main reflector, which can be implemented by the following steps: First, in step 1021, the initial posture feature of the main reflector is obtained, and the initial posture feature includes the plane normal vector and the horizontal deflection angle of the main reflector; Next, in step 1022, a reflection vector of the primary reflector when reflecting light is determined according to the plane normal vector and the illumination path; Then, in step 1023, a reference angle between the incident direction of the light of the light source component in the energy-saving lighting device and the reflection direction of the main reflector is calculated according to the reflection vector and the illumination path; Finally, in step 1024, a first deflection angle of a main reflector in the energy-saving lighting device is determined by using the reference angle and the horizontal deflection angle.

[0041] In the specific implementation, firstly, the plane normal vector and horizontal deflection angle of the main reflector are obtained as initial posture features by means of a three-axis accelerometer and a gyroscope installed on the main reflector, and the initial posture features represent the posture values ​​of the initial state of the main reflector, that is, the geometric space position and direction of the main reflector relative to the device coordinate system before the deflection adjustment; secondly, the reflection vector of the main reflector when reflecting the light is calculated based on the geometric law of light reflection, that is, the reflection vector of the main reflector when reflecting the light is determined by the dot product of the path vector of the illumination path and the plane normal vector, and the illumination path is the reflection vector of the main reflector when reflecting the light. The path vector of the illumination path is a vector representation of the path that the light travels from the light source component to the surface of the target object, that is, a numerical value that characterizes the illumination path, and the reflection vector represents a vector that describes the propagation direction of the reflected light. Further, through the angle relationship between the reflection vector and the path vector of the illumination path, the reference angle between the incident direction of the light source component and the reflection direction of the main reflector is calculated using an inverse cosine function. Finally, the absolute difference between the horizontal deflection angle and the reference angle is calculated, and the absolute difference calculation result is used as the first deflection angle of the main reflector in the energy-saving lighting device.

[0042] It should be noted that the first deflection angle of the main reflector in the present application represents the angular deflection of the main reflector. In the energy-saving equipment control of the smart sheep house, by determining the first deflection angle, the focus and irradiation direction of the light can be accurately controlled, which is very important for improving lighting efficiency and beam quality. The correct deflection angle can ensure that the light is concentrated on the target area, reduce the scattering and waste of light, and avoid the problem of uneven light distribution in the lighting area of ​​the smart sheep house due to the complex spatial layout.

[0043] In step 103, the main reflector is controlled to deflect according to the first deflection angle. When the main reflector is deflected to a predetermined angle, a second posture feature of the main reflector is extracted, and multiple edge radial distances between the auxiliary reflector and the outer edge of the target illumination area are determined.

[0044] In some embodiments, the main reflector is controlled to deflect according to the first deflection angle. When the main reflector is deflected to a predetermined angle, the second posture feature of the main reflector is extracted by the following steps, namely: generating a first angle control signal of the main reflector in the energy-saving lighting device according to the first deflection angle; Based on the first angle control signal, the servo motor in the main reflector is driven to deflect, and the deflection angle of the main reflector is collected in real time. When the main reflector is deflected to a predetermined angle, the second posture feature of the main reflector is extracted.

[0045] In specific implementation, first, a first angle control signal of the main reflector is automatically generated according to the calculated first deflection angle, and the first angle control signal is input into the servo control system to drive the servo motor connected to the main reflector to realize the deflection operation. During the deflection process, the current deflection angle is monitored by a real-time angle sensor (such as a rotary encoder or an angle position sensor) installed on the main reflector. When it is monitored that the deflection angle of the main reflector reaches a predetermined angle, the second posture feature of the main reflector is extracted by the posture sensor, including a new plane normal vector, a horizontal deflection angle and a light incident direction.

[0046] It should be noted that, in this embodiment, the first angle control signal represents a signal for adjusting the angle size in the main reflector. By determining the first angle control signal, the main reflector can be effectively adaptively deflected to improve the effectiveness of lighting; the second posture feature in this application represents the posture value of the main reflector after angle deflection, that is, the geometric spatial position and direction of the main reflector relative to the device coordinate system after the deflection adjustment.

[0047] In some embodiments, the following steps may be used to determine the radial distances between the auxiliary reflector and the outer edge of the target illumination area, namely: Extract all outer edge contour points of the target lighting area; Obtaining the center position coordinates of the auxiliary reflector; The distance between each outer edge contour point and the coordinates of the center position of the auxiliary reflector is calculated, and the calculated distance is used as the edge radial distance, thereby obtaining multiple edge radial distances between the auxiliary reflector and the outer edge of the target illumination area.

[0048] In the specific implementation, first, all outer edge contour points of the target lighting area are extracted through edge detection algorithms (such as Canny, Sobel); the central position coordinates of the auxiliary reflector are obtained by using a position information sensor; the distance between each outer edge contour point and the central position coordinates of the auxiliary reflector is calculated by Euclidean distance, and the calculated distance is used as the edge radial distance, thereby obtaining multiple edge radial distances between the auxiliary reflector and the outer edge of the target lighting area.

[0049] It should be noted that, in this embodiment, the outer edge contour point represents the contour point on the boundary of the target lighting area, and the outer edge contour point defines the precise boundary of the target lighting area, which is crucial to ensure that the light is effectively confined to a specific area and to avoid light overflowing to places where lighting is not required; the edge radial distance in this application refers to the straight-line distance between the outer edge contour point of the target lighting area and the center position of the auxiliary reflector. By calculating the edge radial distance, the angle and position of the auxiliary reflector can be adjusted to ensure that the outer edge of the target lighting area can also obtain uniform lighting.

[0050] In step 104, a reflection path of the auxiliary reflector is constructed by combining all edge radial distances with the center point of the target lighting area, and then a second deflection angle of the auxiliary reflector in the energy-saving lighting device is determined according to the reflection path and the second posture feature.

[0051] In some embodiments, the reflection path of the auxiliary reflector is constructed by combining all edge radial distances with the center position point of the target illumination area, and the following steps can be used, namely: Calculating the distance from the center position point of the target illumination area to the center position point of the auxiliary reflector to obtain the center distance; Compare and analyze each edge radial distance with the center distance to obtain a distance deviation value corresponding to each edge radial distance; The edge radial distance corresponding to the minimum distance deviation is extracted from all distance deviation values, and the extracted edge radial distance is used as the reflection path of the auxiliary reflector.

[0052] In specific implementation, first, the distance from the center position point of the target illumination area to the center position point of the auxiliary reflector is calculated by Euclidean distance to obtain the center distance, and the center distance represents the distance between the two center points; secondly, the difference between each edge radial distance and the center distance is calculated to obtain the distance deviation value corresponding to each edge radial distance, and the distance deviation represents the deviation amount of the two distances; finally, the edge radial distance corresponding to the minimum distance deviation is extracted from all distance deviation values, and the extracted edge radial distance is used as the reflection path of the auxiliary reflector.

[0053] It should be noted that the reflection path in the present application refers to the path of light reflected by the auxiliary reflector, that is, the path of the light source after being reflected by the auxiliary reflector and finally reaching the target lighting area. The reflection path describes the process of light reflection on the surface of the auxiliary reflector. By determining the reflection path, the energy-saving lighting equipment can be effectively guided to make efficient light distribution adjustments, thereby ensuring that the light is concentrated on the target lighting area, reducing light scattering and waste, and thus avoiding regional differences in uneven light distribution.

[0054] In some embodiments, the second deflection angle of the auxiliary reflector in the energy-saving lighting device may be determined according to the reflection path and the second posture feature by using the following steps, namely: Extracting a reference incident vector of the main reflector from the second posture feature; Calculating a reference reflection vector of the auxiliary reflector based on a reference incident light direction of the primary reflector; A second deflection angle of the auxiliary reflector in the energy-saving lighting device is determined according to a reference reflection vector of the auxiliary reflector and the reflection path.

[0055] In the specific implementation, first, the illumination incident direction is extracted from the second posture feature, and the illumination incident direction is used as a reference incident vector, the reference incident vector represents an incident vector for reference, that is, an incident vector incident from the main reflector to the auxiliary reflector; secondly, based on the law of reflection, that is, the incident angle is equal to the reflection angle, the reference reflection vector of the auxiliary reflector is calculated according to the reference incident vector of the main reflector, the reference reflection vector represents a reflection vector for reference, that is, a reflection vector reflected from the auxiliary reflector to the target lighting area; finally, the angle between the reference reflection vector of the auxiliary reflector and the path vector of the reflection path is calculated by means of vector dot product, and the calculated angle is used as the second deflection angle of the auxiliary reflector in the energy-saving lighting device.

[0056] It should be noted that the second deflection angle in the present application represents the angular deflection of the auxiliary reflector. In the energy-saving equipment control of the smart sheep house, the auxiliary reflector needs to accurately irradiate the reflected light to the target lighting area.
