Description

Technical Field

[0001] The present invention relates to the technical field of lighting control, and more particularly to an induction lamp linkage control system. Background Art

[0002] As an intelligent, energy-saving and environmentally friendly lighting device, the application scenarios of induction lamps mainly include various lighting occasions in the home, such as bathrooms, corridors, stairs, kitchens, etc.; commercial places, such as shops, offices, hotels, hospitals, etc.; public places such as underground garages, subway stations, airports, parks, etc. The existing technologies of induction lamps include infrared sensing, microwave sensing, voice-controlled sensing, light-controlled sensing, etc.

[0003] Under normal conditions, the sensor light is off when it does not receive a sensing signal. When a person walks into the range of the scene, the sensor lights within the range are simply triggered by a certain technology to receive the signal and light up according to the brightness and color temperature parameters set by the sensor light itself. The installation position of each sensor light and the scene position can easily cause the light in some locations to be too dark or too bright, and each sensor light cannot be linked to each other. If the sensing function of the sensor light is reduced, it is easy for the sensor light to fail to light up and fail to meet the lighting effect requirements. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a sensor light linkage control system. This sensor light linkage control system, by establishing a sensor light linkage network, can realize correction and control of the lights in the network according to the light distribution in the scene and whether there is an auxiliary light source, so as to achieve the best lighting effect.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An induction lamp linkage control system includes an edge induction lamp arranged at the edge of a wall and a top induction lamp arranged at the top of a wall, and further includes:

[0007] A sensing signal acquisition module, which acquires a sensing signal collected by a sensor provided in the edge sensing light as a triggering sensing signal of the edge sensing light;

[0008] A sensor information acquisition module, which acquires the brightness value and illumination range below respectively acquired by the sensor provided in the top induction lamp as illumination information and illumination area information, wherein the illumination information corresponds to the illumination area information one by one;

[0009] A light source identification module, which compares the illumination information with a preset brightness threshold N1 to obtain an illumination area under the abnormal brightness value, wherein the illumination area includes a bright illumination area corresponding to a large abnormal brightness value and a low illumination area corresponding to a small abnormal brightness value;

[0010] The light correction module calculates the overlap between the range of the bright illumination area and the illumination range of the top sensor light in the low illumination area, compares the overlap with a preset overlap threshold N2, and outputs a gradual reinforcement strategy or a sudden reinforcement strategy for the top sensor light according to the comparison result.

[0011] Furthermore, it also includes an illumination anomaly verification module, which defines the top sensor light corresponding to the illumination bright area as the auxiliary light position, defines the top sensor light corresponding to the edge sensor light that triggers the sensing signal as the lighting light position, marks the coordinate points of the auxiliary light position and the lighting light position in the preset three-dimensional scene, and calculates the distance value between the auxiliary light position and the lighting light position based on the coordinate points, compares the distance value with the preset distance threshold N3, and outputs the reinforcement sudden change strategy or the reinforcement ignore strategy of the top sensor light corresponding to the auxiliary light position based on the comparison result.

[0012] Furthermore, the photometric correction module includes a brightness model building submodule and a brightness enhancement matching submodule.

[0013] The brightness model construction submodule inputs a number of historical data into the neural network in proportion for training, verification and testing to obtain a brightness reinforcement model, wherein the historical data includes the height of the top sensor light, the reinforcement brightness value of the top sensor light and the brightness value below;

[0014] The enhanced brightness matching submodule matches the illumination information through a brightness enhancement model to obtain an enhanced brightness value.

[0015] Furthermore, the illumination abnormality verification module uses the image acquired in the external camera system as real-time image information, and determines whether there is an auxiliary light source through a bright spot recognition strategy according to the real-time image information. If there is, a coincidence comparison instruction is output, otherwise, a coincidence ignore instruction is output;

[0016] The bright spot identification strategy includes a bright spot analysis step and a bright spot screening step.

[0017] The bright spot analysis step is to obtain a grayscale image through grayscale processing according to the real-time image information, select pixel values ​​with a large number of identical pixel values ​​as background pixels, and mark pixel values ​​with a large deviation from the background pixels as bright spot pixels;

[0018] The bright spot screening step maps the bright spot pixels in a preset scene three-dimensionally to obtain bright spot position coordinates, and compares the bright spot position coordinates with the position coordinates of the edge sensing light. If they coincide, the output bright spot is the edge sensing light, otherwise, the output bright spot is the auxiliary light source.

[0019] Furthermore, it also includes a linkage control module, which determines the walking direction of the pedestrian according to the real-time image information through a behavioral dynamic analysis strategy, estimates the walking trajectory of the pedestrian according to the walking direction, and pre-controls the opening of the next edge sensor light and the top sensor light based on the walking trajectory.

[0020] Furthermore, the sensor information acquisition module obtains the distance value collected by the sensor provided in the top induction light as the direct distance;

[0021] The photometric correction module inputs the direct distance into the brightness enhancement model and indexes it to obtain the enhanced brightness value of the top sensor light.

[0022] Furthermore, it also includes a height calculation module, which matches the actor target through the target detection model according to the real-time image information, maps the coordinates of the actor target in the preset three-dimensional scene, determines the relative position of the top sensor light and the actor target, and calculates the vertical distance between the top sensor light and the actor target as the direct distance.

[0023] Furthermore, the sensing signal acquisition module includes a sensing signal verification submodule.

[0024] The sensing signal verification submodule compares the coordinates of the target actor mapped in the preset three-dimensional scene with the position coordinates of the edge sensing light, and determines whether the comparison result is the same as the interval distance converted by the sensing signal. If they are the same, a normal instruction is output; otherwise, an edge sensing light sensing correction instruction is output.

[0025] Furthermore, the linkage control module calculates the walking speed of the actor target based on the coordinates of the actor target mapped in the three-dimensional space of the preset scene within a certain period of time, controls the lighting time of subsequent top sensor lights in the walking trajectory based on the walking speed, and superimposes the lighting time of subsequent top sensor lights based on the walking speed.

[0026] Furthermore, the reinforcement gradual change strategy reflects that the brightness of the top sensor light gradually increases, the reinforcement sudden change strategy reflects that the brightness of the top sensor light instantly increases, and the reinforcement ignoring strategy reflects that the top sensor light ignores turning on.

[0027] The beneficial effects of the present invention are as follows: by setting the edge sensing lights and the top sensing lights to work together, the system can more accurately sense and respond to the lighting changes of the edge sensing lights. When the lighting of the edge sensing lights is insufficient or needs to be adjusted, the system can automatically adjust the lighting intensity of the top sensing lights to ensure that the lighting effect reaches the best state; in addition, the light source recognition module is used to identify areas with abnormal brightness, and low illumination areas and high illumination areas are obtained. The overlap between the high illumination areas and the illumination range of the top sensing lights at the target position of the actor is then judged, so as to provide a reinforcement sudden change strategy or a reinforcement ignore strategy. The purpose is to avoid excessive overlap between the two at the illumination angle when the actor target holds the auxiliary light source, resulting in the top sensing light suddenly lighting up suddenly and damaging the eyes of the actor target.

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0033] In a normal state, the sensor light is off when it does not receive a sensing signal. When a person walks into the scene range, the sensor lights within the range are simply triggered by a certain technology to receive a signal and light up the sensor lights themselves according to the parameter brightness and color temperature set. The installation position of each sensor light and the scene position may easily lead to the situation that the light in some positions is too dark or too bright, and each sensor light cannot be linked. If the sensing function of the sensor light is reduced, it may easily lead to the sensor light not being able to light up and the lighting effect requirement cannot be met. Therefore, the present invention designs such a sensor light linkage control system, such as Figure 4As shown, it includes edge sensor lights arranged at the side of the wall and top sensor lights arranged at the top of the wall. For example, in an indoor corridor in a public area, the top sensor light is located at the center of the ceiling of the corridor and irradiates downward. The edge sensor light is located at the bottom edge of the wall of the corridor. The edge sensor light and the top sensor light are arranged in a group. One top sensor light may correspond to one or two edge sensor lights, such as Figure 1 As shown, it also includes:

[0034] The sensing signal acquisition module obtains the sensing signal collected by the sensor (infrared sensor or microwave sensor) installed in the edge sensing light as the sensing signal for triggering the edge sensing light. When the person walks to point A, the edge sensing light A1 triggers the sensing signal, which is sent to the central system unit, and then controls the edge sensing light A1 to light up.

[0035] The sensor information acquisition module obtains the brightness value and illumination range below collected by the sensor (such as a photosensitive sensor) in the top sensor light as illumination information and illumination area information. The illumination information corresponds to the illumination area information one by one, such as Figure 4 As shown, the edge sensor lights are marked with A1 and A2, and the top sensor lights are marked with B1, B2, B3, B4, B9 and B10, among which B1, B2, B3, B4 are located in front of A, and B9 and B10 are located behind A. When the edge sensor light A1 is on, the top sensor light B1 or the top sensor light Bn simultaneously or separately collects the brightness value of the surroundings of the actor A, which is defined as the lower brightness value. The illumination range is defined according to the brightness value. The surroundings of the actor A can be divided into area C and area D according to the brightness value, that is, the brightness value corresponding to area C is x (lm), and the brightness value corresponding to area D is y (lm).

[0036] The light source recognition module compares the illumination information with the preset brightness threshold N1 to obtain the illumination area under the abnormal brightness value. The illumination area includes the bright illumination area corresponding to the large abnormal brightness value and the low illumination area corresponding to the small abnormal brightness value. The brightness value x and the brightness value y are compared with the brightness threshold N1. Under normal circumstances, the actor A is located at A, and the brightness value x in area C should be the same or close to the brightness threshold N1. If it is less than the brightness threshold N1, it means that the edge sensor lamp A1 is damaged. At this time, the top sensor lamp will increase the power to compensate for the light, so that the brightness of each area in the corridor is the same; its role is to set the edge sensor lamp and the top sensor lamp to work together, so that the system can more accurately perceive and respond to the light changes of the edge sensor lamp, when the light of the edge sensor lamp is insufficient or needs to be adjusted;

[0037] Of course, person A can be located in different positions, and the distance detection can be performed on him based on the edge sensing light A1 to determine the distance from person A to match the brightness thresholds in different areas. Assuming that the brightness value y in area D is greater than the brightness threshold N1, it can be preliminarily determined that person A is holding an auxiliary light source, such as a mobile phone, a flashlight, etc.

[0038] The luminosity correction module, when the auxiliary light source is identified and analyzed, that is, according to the overlap between the range of the calculated bright illumination area (area D) and the illumination range of the top sensor light in the low illumination area (the illumination range of the top sensor light B1), the overlap is compared with the preset overlap threshold value N2, and the reinforcement gradual change strategy or the reinforcement sudden change strategy of the top sensor light is output according to the comparison result, wherein the reinforcement gradual change strategy reflects that the brightness of the top sensor light gradually increases, and the reinforcement sudden change strategy reflects that the brightness of the top sensor light increases instantly. When the overlap between the two is greater than the overlap threshold value N2, it means that the auxiliary light source is illuminating the area under the feet, which is closer to the actor A and is located within the range of the top sensor light B1. The lighting mode of the top sensor light B1 should be gradually enhanced. If it is directly enhanced instantly, it is easy to cause the actor A to feel uncomfortable instantly. When the overlap between the two is less than the overlap threshold value N2, it means that the auxiliary light source may be shining forward, and the area D of the auxiliary light source may be located in the lighting area corresponding to the top sensor light B3. At this time, the top sensor light B3 can be controlled to be instantly enhanced and lit.

[0039] The function of the light source correction module is to identify the area with abnormal brightness through the light source recognition module, obtain the low illumination area and the high illumination area, and then judge the overlap between the high illumination area and the illumination range of the top sensor light at the target position of the actor, so as to give a reinforcement sudden change strategy or a reinforcement ignore strategy. Its purpose is to avoid that when the actor target holds the auxiliary light source at the illumination angle, the two overlap too much, causing the top sensor light to suddenly light up and damage the actor target's eyes.

[0040] like Figure 1As shown, it also includes an illumination abnormality verification module, which defines the top sensor light corresponding to the bright illumination area as the auxiliary light position, defines the top sensor light B1 corresponding to the edge sensor light A1 that triggers the sensing signal as the lighting light position, marks the coordinate points of the auxiliary light position and the lighting light position in the preset three-dimensional scene, and calculates the distance value between the auxiliary light position and the lighting light position according to the coordinate points (if the corridor length is defined as the y-axis, the width is defined as the x-axis, and the height is defined as the y-axis, then the distance value should be the distance in the y-axis direction), and compares the distance value with the preset distance threshold N3. At this time, the distance threshold N3 should only consider that the illumination range of area D and the top sensor light B1 does not overlap at all. According to the comparison result, the reinforcement sudden change strategy or the reinforcement ignore strategy of the top sensor light corresponding to the auxiliary light position is output, wherein the reinforcement ignore strategy reflects that the top sensor light is ignored to be turned on. For example, when the actor A holds a flashlight and the illumination bright area of ​​the flashlight is at the end of the corridor, it is too far away from the actor A. At this time, even if the illumination bright area is detected, the system also outputs that the corresponding top sensor light is ignored to be turned on.

[0041] like Figure 1 As shown, the photometric correction module includes a brightness model building submodule and a reinforcement brightness matching submodule.

[0042] The brightness model construction submodule divides several historical data (the height of the top sensor light, the enhanced brightness value of the top sensor light, and the brightness value below) into a training set, a validation set, and a test set according to a ratio of 7:2:1. The training set is used to train a multi-layer neural network (such as a multi-layer perceptron MLP, a convolutional neural network CNN, or a recurrent neural network RNN) so that it can learn the relationship between brightness, height, and enhanced brightness to obtain a brightness enhancement model. The model is then verified by the validation set to evaluate the performance of the model and avoid overfitting. Finally, the model is tested by the test set to ensure the accuracy and reliability of the model during application. In addition, an update submodule can be designed to periodically update the model.

[0043] The enhanced brightness matching submodule matches the brightness value collected by the top sensor light through the brightness enhancement model to obtain the enhanced brightness value of the top sensor light that needs to be turned on. In addition, the sensor information acquisition module can be used to obtain the distance value collected by the sensor built into the top sensor light as the direct distance. The light correction module inputs the direct distance into the brightness enhancement model to obtain the enhanced brightness value of the top sensor light.

[0044] Since the data collected by the photosensitive sensor is affected by the installation position and angle, there may be omissions or inaccuracies. Figure 2As shown, in the illumination abnormality verification module, surveillance cameras are generally installed in public corridors, so the image obtained from the external camera system is used as real-time image information. According to the real-time image information, the bright spot recognition strategy is used to determine whether there is an auxiliary light source. If so, a coincidence comparison instruction is output, otherwise, a coincidence ignore instruction is output;

[0045] Among them, the highlight identification strategy includes a highlight analysis step and a highlight screening step.

[0046] The bright spot analysis step is to obtain a grayscale image through grayscale processing based on the real-time image information, wherein the grayscale image only contains brightness information but not color information, and selects pixel values ​​with more identical pixel values ​​as background pixels, that is, in a grayscale image, the area with more identical pixel values ​​is the background area, that is, the dark area. When the pixel value of a certain place is different from the background pixel, it means that the area is an auxiliary light source, that is, the pixel value with a large deviation from the background pixel is marked as a bright spot pixel;

[0047] The bright spot screening step is firstly to map the bright spot position, mapping the identified bright spot pixels in the preset scene three-dimensional to obtain the bright spot position coordinates. Similarly, the position of the edge sensor light is also mapped in the preset scene three-dimensional;

[0048] Secondly, position coordinate comparison: compare the position coordinates of the bright spot with the position coordinates of the edge sensor light. According to the position coordinate comparison result, determine whether the bright spot is generated by the edge sensor light or the auxiliary light source. If the position of the bright spot coincides with or is close to the position of the edge sensor light, the output bright spot is the edge sensor light. If the position of the bright spot is obviously inconsistent with the position of the edge sensor light, the output bright spot is the auxiliary light source.

[0049] Through the above-mentioned bright spot analysis steps and bright spot screening steps, the system can accurately identify the bright spots in the image and determine whether these bright spots are generated by edge sensor lights or auxiliary light sources, so as to ensure the verification of the analysis of the auxiliary light source and avoid the system from misjudging and incorrectly controlling the turning on of the top sensor light. In addition, it can also ensure the turning on brightness value of the top sensor light and ensure that the lighting in the corridor is uniform.

[0050] Since traditional induction lights are installed separately, each induction light will light up alone only when it triggers a sensing signal. Therefore, in order to realize the control of the induction lights, the system also includes a linkage control module, which determines the walking direction of pedestrians through a behavior dynamic analysis strategy based on real-time image information. The behavior dynamic analysis strategy includes pedestrian detection. In the acquired image, the target detection algorithm is used to detect pedestrians and give the pedestrian's position in the preset three-dimensional scene;

[0051] Walking direction judgment: By analyzing the posture, facial orientation or position changes of the person in continuous frame images, the walking direction of the pedestrian can be judged;

[0052] Walking trajectory prediction, based on the walking direction through the prediction algorithm to estimate the walking trajectory of pedestrians, helps to know in advance the areas that the person may reach; then according to the walking trajectory, some sensor lights in the trajectory can be controlled to light up synchronously. During the person's walking process, the trajectory is monitored and updated to control the turning on or off of the sensor lights, avoiding unnecessary lighting waste, thereby achieving energy saving and consumption reduction effects, and the sensor lights in the target area can be turned on in advance to facilitate the person's walking.

[0053] In addition, the linkage control module calculates the walking speed of the actor's target according to the coordinates mapped in the preset scene three-dimensionally within a certain period of time, controls the lighting time of the subsequent top sensor lights in the walking trajectory according to the walking speed, and superimposes the lighting time of the subsequent top sensor lights according to the walking speed. For example, if the system uniformly controls the turning-on time of the top sensor lights to be 60s, when the actor is located at the top sensor light B1, B1 lights up and lasts for 60s. At this time, the walking trajectory also estimates that the top sensor lights B2, B3 and B4 on the walking trajectory are all lit up for an initial 60s. According to the actor's walking speed, the top sensor lights B2 and B3 are delayed and superimposed so that when the actor walks to the illumination range of the top sensor lights B2 and B3, the lighting time of the top sensor lights B2 and B3 can still last for 60s. In addition, according to the actor's position monitoring, if the actor continues to be located below the top sensor light B2, the sensor light B2 is controlled to continue to cycle for 60s. The system ensures the continuity of lighting and avoids lighting blind spots caused by delayed lighting of the sensor lights.

[0054] Since the height of the person determines the distance between the eyes and the light source, the taller the person is, the more dazzling the light source will be. Figure 3 As shown, it also includes a height calculation module, which matches the actor's target through the target detection model according to the real-time image information, maps the coordinates of the actor's target in the preset three-dimensional scene, determines the relative position of the top sensor light and the actor's target, and calculates the vertical distance between the top sensor light and the actor's target as the direct distance, wherein the direct distance is used as the reinforced brightness value of the top sensor light outputted into the model, with the purpose of enabling the system to provide personalized lighting experience according to the actor's height (or the distance between the eyes and the light source), avoiding the discomfort caused by the glare of the light source, and realizing intelligent control of the lighting system, which can automatically adjust the lighting status according to the real-time situation.

[0055] The sensing signal acquisition module includes a sensing signal verification submodule.

[0056] The sensing signal verification submodule compares the coordinates of the actor's target mapped in the preset three-dimensional scene with the position coordinates of the edge sensing light, and determines whether the comparison result is the same as the interval distance converted from the sensing signal (converting the physical signals detected by the sensing light, such as light intensity changes, infrared signals, etc., into digital signals or distance values). If they are the same or within an acceptable error range, a normal instruction is output. The normal instruction indicates that the sensing signal is accurate, or that the system is currently in a normal state. Otherwise, an edge sensing light sensing correction instruction is output. The correction instruction indicates that the sensitivity, position or calibration parameters of the sensing light need to be adjusted to improve the accuracy of the sensing signal.

[0057] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
