It should be understood that these embodiments are provided only to enable those skilled in the art to better understand and implement the present invention, and are not intended to limit the scope of the present invention in any way. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0019] Those skilled in the art know that the embodiments of the present invention can be implemented as a system, device, apparatus, method or computer program product. Therefore, the present invention can be specifically implemented in the following forms, namely: complete hardware, complete software (including firmware, resident software, microcode, etc.), or a combination of hardware and software.

[0020] It should be noted that any number of elements in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.

[0021] Reference below Figure 1 , Figure 1 This is a flow chart of a matrix radar sensor light group management system provided by an embodiment of the present invention. Figure 1 As shown, a matrix radar sensor light group management system 100 includes: Step 101, setting a radar sensor light group in a matrix layout, and detecting targets in a coverage area through radar sensors; Step 102, obtaining radar detection data of targets within the coverage area; Step 103, based on the control differential equation of the matrix radar sensing light group, obtain the lighting control solution equation of the light group under the radar detection data; Step 104, based on the radar detection data of the target and the lighting control solution equation, obtain the lighting response of the target at different positions and select the one with the largest response value as the maximum lighting response; Step 105, obtaining the lighting efficiency and energy-saving effect of the light group based on the maximum lighting response and the lighting efficiency calculation equation and energy-saving effect calculation equation of the matrix radar sensing light group.

[0022] It should be noted that this embodiment describes a matrix radar sensor light group management system, which detects targets in the coverage area by setting up a matrix layout of radar sensor light groups. Here, the matrix layout means that the light group is composed of multiple LED lamp beads, and these lamp beads are arranged in a certain row and column arrangement to form a matrix structure. A radar sensor is a device that can emit and receive radar waves to detect the position and movement of a target.

[0023] Specifically, the system includes a row control unit and a column control unit, which are responsible for controlling the rows and columns of the light group respectively to achieve independent control of each LED lamp bead. The radar sensor is integrated with the light group, which means that the sensor is designed to be integrated with the light group, can directly detect targets in the coverage area, and adjust the lighting strategy of the light group according to the detection results. For example, the radar sensor can be set to increase the brightness when a moving target is detected, and reduce the brightness or turn it off when no target is detected.

[0024] Preferably, the brightness and on / off state of each LED lamp bead of the system can be dynamically adjusted according to the detection results of the radar sensor. This means that the system can adjust the lighting strategy in real time according to the specific location and movement trajectory of the target to achieve the best lighting effect and energy saving effect. For example, the system can preset different brightness levels and lighting modes to select the most appropriate lighting solution according to the distance and movement speed of the target.

[0025] Furthermore, the system can also further improve the speed and accuracy of lighting response through algorithm optimization, ensuring that energy consumption is minimized while meeting lighting needs.

[0026] In some embodiments, the layout of the radar sensor light group in a matrix layout is as follows: The light group is composed of multiple LED lamp beads, arranged in a matrix, and each LED lamp bead is independently controlled; The matrix-layout radar sensor light group includes a row control unit and a column control unit, which are used to control the rows and columns of the light group respectively; The radar sensor is integrated with the light group to detect targets in the coverage area and adjust the lighting strategy of the light group according to the detection results; The brightness and switch status of each LED lamp bead in the matrix-layout radar sensor light group are dynamically adjusted according to the detection results of the radar sensor.

[0027] It should be noted that this embodiment relates to a radar sensor light group with a matrix layout, which is composed of multiple LED lamp beads and arranged in a matrix, and each LED lamp bead is independently controlled. Here, the matrix arrangement means that the lamp beads are distributed in a certain row and column structure, similar to the pixel arrangement on an electronic display screen, and independent control means that each lamp bead can receive a control signal individually to adjust its brightness or switch state.

[0028] Specifically, this matrix-layout radar sensor light group includes a row control unit and a column control unit, which are used to control the rows and columns of the light group respectively. The row control unit is responsible for sending control signals to the LED lamp beads in each row, while the column control unit is responsible for sending control signals to the LED lamp beads in each column. The radar sensor is integrated with the light group, that is, the radar sensor is designed to be integrated with the light group, which can directly detect targets in the coverage area and adjust the lighting strategy of the light group according to the detection results. For example, the radar sensor can be configured to send a signal to the control unit when a target is detected to adjust the brightness of the LED lamp beads in the corresponding area.

[0029] Preferably, the brightness and switch state of each LED lamp bead of the matrix-layout radar sensor light group are dynamically adjusted according to the detection results of the radar sensor. This means that the system can adjust the lighting strategy in real time according to the specific location and movement trajectory of the target to achieve the best lighting effect and energy saving effect. For example, the system can preset different brightness levels and lighting modes to select the most appropriate lighting solution according to the distance and movement speed of the target.

[0030] Furthermore, the system can also further improve the speed and accuracy of lighting response through algorithm optimization, ensuring that energy consumption is minimized while meeting lighting needs. As an alternative, other types of sensors, such as infrared sensors or ultrasonic sensors, can be considered to adapt to different application scenarios and environmental conditions.

[0031] In some embodiments, radar detection data of targets within the coverage area is obtained by the following formula: (1); In the formula, The target in the coverage area is located at Radar detection data at is the amplitude of the detection signal, is the circular frequency of the detection signal, To detect the phase of the signal, For time.

[0032] It should be noted that this embodiment describes a method for obtaining radar detection data of a target within a coverage area. Here, radar detection data refers to data collected by a radar sensor about the position, speed, and other information of a target within a coverage area. This method calculates the radar detection data of a target at a position (x, y) by a specific formula, which involves parameters such as the amplitude, circular frequency, phase, and time of the detection signal.

[0033] Specifically, the amplitude in the formula refers to the strength of the radar signal, the circular frequency refers to the frequency of the radar signal, the phase refers to the time offset of the signal waveform, and the time is the time point of signal transmission and reception. These parameters together determine the characteristics of the radar signal and how it is used to detect and identify targets.

[0034] More specifically, in practical applications, these parameters can be adjusted according to the characteristics of the environment and the target to optimize the detection effect. For example, different amplitudes and frequencies can be set to adapt to the detection of targets at different distances and speeds.

[0035] Preferably, in order to improve the accuracy and reliability of the detection data, a variety of signal processing technologies can be used to optimize the acquisition process of radar detection data. For example, digital signal processing technology can be used to filter out noise and interference and improve the signal-to-noise ratio of the signal.

[0036] Furthermore, the detection accuracy can be improved by adjusting the radar sensor's transmit power and receiving sensitivity, as well as optimizing the algorithm. As an alternative, you can consider using the Doppler effect to measure the target's speed, or using frequency modulated continuous wave (FMCW) radar technology to improve the detection distance and speed resolution. The application of these technologies can further improve the system's performance and adapt it to a wider range of application scenarios.

[0037] In some embodiments, the control differential equation of the matrix radar sensor light group is: (2); In the formula, is the lighting brightness of the lamp group, and is the control parameter of the lamp group, is the coefficient of the detection signal’s influence on the lighting brightness, The target in the coverage area is located at Radar detection data at the site.

[0038] It should be noted that this embodiment relates to the control differential equation of the matrix radar sensing light group. This equation is a mathematical model used to describe how the lighting brightness of the light group changes with the control parameters. Here, the control differential equation is an equation that includes the lighting brightness of the light group (L), the control parameters (a and b), the coefficient of the influence of the detection signal on the lighting brightness (c), and the radar detection data (P(x, y)) of the target at the position (x, y) in the coverage area.

[0039] Specifically, the lighting brightness L in the control differential equation represents the brightness level of the light group, the control parameters a and b are variables used to adjust the response characteristics of the light group, the coefficient c is a parameter that describes the influence of the radar detection signal on the lighting brightness, and P(x, y) is the radar detection data of the target at a specific position.

[0040] More specifically, in actual settings, these parameters can be adjusted according to the specific characteristics of the light group and the application environment. For example, control parameters a and b can be set as constants related to the physical characteristics of the light group, while coefficient c can be adjusted according to the sensitivity of the radar sensor.

[0041] Preferably, in order to more accurately control the lighting brightness of the lamp group, the parameter settings in the control differential equation can be further refined. For example, more control parameters can be introduced to describe the lighting requirements under different environmental conditions, or an adaptive algorithm can be used to dynamically adjust these parameters.

[0042] Furthermore, advanced numerical methods can be considered to solve the control differential equations to obtain faster and more accurate lighting control strategies. As an alternative, intelligent control technologies such as fuzzy logic or neural networks can be considered to handle complex lighting control problems, which can better handle uncertainty and nonlinear problems and improve the overall performance and adaptability of the system.

[0043] In some embodiments, the lighting control equation of the light group under radar detection data is: (3); in, The lighting brightness of the matrix radar sensor light group. is the total order of the lighting model, is the illumination calculation coefficient of each order mode, which is a constant in the same order mode. is the natural frequency of the matrix radar sensor light group, is the phase of each mode.

[0044] It should be noted that this embodiment describes the lighting control solution equation of the light group under radar detection data. This equation is used to calculate the lighting brightness of the matrix radar sensing light group, which involves the total order of the lighting model, the lighting calculation coefficient of each order mode, the natural frequency of the matrix radar sensing light group, and the phase of each order mode. Here, the lighting control solution equation is a mathematical expression used to determine the lighting strategy of the light group based on the radar detection data.

[0045] Specifically, the total order of the lighting model in the lighting control solution equation refers to the number of modes considered in the model, which determines the complexity and accuracy of the lighting control. The lighting calculation coefficients of each order mode are constants that remain unchanged in the same order mode, and they are related to the physical characteristics and design parameters of the light group. The natural frequency of the matrix radar sensing light group refers to the natural vibration frequency of the light group when there is no external influence, and the phase of each order mode refers to the phase difference of the lighting response under different modes. In practical applications, these parameters can be measured experimentally or calculated based on the design parameters of the light group.

[0046] Preferably, in order to improve the accuracy and response speed of lighting control, the parameter settings in the lighting control solution equation can be further refined. For example, a higher precision sensor can be used to obtain radar detection data, or a more complex model can be used to improve the accuracy of the modal lighting calculation coefficient.

[0047] Furthermore, the working status of the light group can be monitored in real time, and the natural frequency and phase parameters can be dynamically adjusted to adapt to environmental changes and target movement. As an alternative, machine learning algorithms can be used to optimize the lighting control equations, automatically adjust parameters by learning historical data and environmental feedback, and improve the intelligence level of lighting control.

[0048] In some embodiments, based on radar detection data and a lighting control solution equation, obtaining lighting responses of a target at different positions and selecting the largest response value as the maximum lighting response includes: The radar detection data of the target in the coverage area obtained by formula (1) is used as the input of the lighting control solution equation (3). Equation (3) is solved to obtain the lighting response of the target at different positions, and the one with the largest response value is selected as the maximum lighting response.

[0049] It should be noted that this embodiment describes a process of obtaining the illumination response of a target at different positions based on radar detection data and the illumination control solution equation and selecting the one with the largest response value as the maximum illumination response. Here, illumination response refers to the degree to which an object is affected by illumination at a specific position, which is usually related to the illumination brightness and the position of the object.

[0050] Specifically, this process involves substituting radar detection data as input into the lighting control solution equation to calculate the lighting response of the target at various positions. These response values ​​reflect the illumination effect of the lighting system on the target at different positions. In actual operation, by setting different detection data inputs and solving the equation, a series of lighting response values ​​can be obtained. Then, by comparing these values, the maximum response value is selected, that is, the maximum lighting effect on the target at a certain position.

[0051] Preferably, in order to more accurately determine the maximum lighting response, the process can be further refined, for example, a higher precision radar detection device can be used to obtain more detailed target position information, or a more complex lighting control solution equation can be used to improve the accuracy of the calculation.

[0052] Furthermore, an optimization algorithm can be introduced to process a large amount of lighting response data and quickly find the maximum value. As an alternative, image processing technology can be used to analyze the lighting effect of the target and use visual feedback to assist in determining the maximum lighting response. This method can provide a more intuitive lighting effect evaluation.

[0053] In some embodiments, the lighting efficiency calculation equation of the matrix radar sensor light group is: (4); in, Radar sensing frequency The lighting efficiency under is the maximum lighting response, is the power consumption of the lamp group.

[0054] It should be noted that this embodiment involves a calculation equation for the lighting efficiency of a matrix radar sensing light group. This equation is used to calculate the lighting efficiency of the light group at a specific radar sensing frequency, which involves the maximum lighting response and the power consumption of the light group. Here, lighting efficiency refers to the ratio between the energy consumption and the lighting effect of the light group while providing sufficient lighting.

[0055] Specifically, the maximum lighting response in the lighting efficiency calculation equation refers to the strongest lighting effect on the target in all possible positions, while power consumption refers to the electrical energy consumed by the lamp group during operation. This equation evaluates the energy efficiency performance of the lamp group through these two parameters.

[0056] More specifically, in practical applications, the specific values ​​of these two parameters can be obtained by measurement or calculation, and they can be substituted into the equation to obtain the specific value of lighting efficiency. For example, if the maximum lighting response is 100 units and the power consumption is 50 watts, the lighting efficiency can be calculated based on these values.

[0057] Preferably, in order to calculate the lighting efficiency more accurately, the parameter settings in the lighting efficiency calculation equation can be further refined. For example, a high-precision sensor can be used to measure power consumption, or an advanced algorithm can be used to more accurately predict the maximum lighting response.

[0058] Furthermore, the impact of environmental factors, such as temperature and humidity, on lighting efficiency can be considered and taken into account in the calculation. As an alternative, the actual energy consumption data and long-term monitoring results of lighting effects can be used to calibrate the lighting efficiency calculation equation to improve its accuracy and practicality. This method can help users better understand the energy efficiency performance of lamp groups and provide data support for energy-saving optimization.

[0059] In some embodiments, the energy-saving effect calculation equation of the matrix radar sensor light group is: (5); In the formula, Radar sensing frequency Energy saving effect under is a constant, To motivate time, is the maximum lighting response.

[0060] It should be noted that this embodiment describes the energy-saving effect calculation equation of the matrix radar sensing light group. This equation is used to calculate the energy-saving effect of the light group at a specific radar sensing frequency, involving parameters such as constants, excitation time, and maximum lighting response. Here, the energy-saving effect refers to the difference between the energy consumption reduced by optimizing the lighting strategy and the original energy consumption.

[0061] Specifically, the constants in the energy-saving effect calculation equation refer to the fixed parameters used in calculating the energy-saving effect, which may be related to the specific characteristics of the lamp group or environmental conditions. The excitation time refers to the duration of the lamp group being activated within a certain period of time, and the maximum lighting response refers to the strongest lighting effect received by the target in all possible positions. These parameters together determine the energy-saving effect of the lamp group.

[0062] More specifically, in actual applications, specific values ​​of these parameters can be set according to the design and use environment of the lamp group, and they can be substituted into the equation to obtain specific values ​​of the energy-saving effect.

[0063] Preferably, in order to calculate the energy saving effect more accurately, the parameter settings in the energy saving effect calculation equation can be further refined. For example, a real-time monitoring system can be used to accurately measure the excitation time, or an advanced algorithm can be used to predict the maximum lighting response.

[0064] Furthermore, the impact of environmental changes in different time periods, such as changes in pedestrian and vehicle traffic, on energy-saving effects can be considered and taken into account in the calculation. As an alternative, the energy-saving effect calculation equation can be calibrated using actual energy consumption data and long-term monitoring results of historical lighting effects to improve its accuracy and practicality.

[0065] The above-mentioned embodiments of the present invention have the following beneficial effects: The matrix radar sensor light group management system described in the present invention can provide an efficient and energy-saving lighting solution. The system detects targets in real time through radar sensors and dynamically adjusts the lighting strategy according to the detection data, so that the lighting brightness and distribution are more in line with actual needs. This intelligent lighting control can not only reduce energy consumption, but also improve the response speed and accuracy of lighting, providing users with a more comfortable lighting environment. In addition, the system accurately calculates the lighting response by controlling differential equations and solving lighting control equations, ensuring that the maximum energy saving effect is achieved while meeting lighting needs.

[0066] The system design also includes quantitative analysis of lighting efficiency and energy-saving effects, which can provide users with intuitive data support to help them better understand and manage the energy usage of the lighting system. By precisely controlling the brightness and switch status of each LED lamp bead, the system can achieve more refined lighting management and further improve lighting efficiency and energy-saving effects. This lighting control strategy based on radar detection data enables the lighting system to adapt to different environments and needs more flexibly, and can provide an effective technical means to achieve green and energy-saving lighting.

[0067] Example 1 The following is an example of a specific application scenario. In a large underground parking lot, the parking lot area is large, vehicles and pedestrians pass frequently, and the traditional lighting method has high energy consumption and unsatisfactory lighting effect.

[0068] System layout: First, a matrix radar sensor light group consisting of 50×50 LED lamp beads is selected and evenly distributed on the ceiling of the parking lot. Each LED lamp bead can be controlled independently, and the row control unit and column control unit are responsible for controlling the rows and columns of the light group respectively. The radar sensor is tightly integrated with the light group to effectively detect vehicles and pedestrians in the coverage area.

The device includes a layout module, a data acquisition module, a control equation solving module, a response analysis module, and an efficiency and energy saving analysis module. Here, the layout module refers to a component for configuring and setting a matrix layout of radar sensor light groups, and the data acquisition module refers to a component for collecting radar detection data of targets within the coverage area.

[0082] Specifically, the layout module is responsible for setting the physical layout and connection method of the light group to ensure that each LED lamp bead can be arranged in a matrix and independently controlled. The data acquisition module contains a radar sensor for real-time detection and collection of the target's position and movement information. The control equation solving module uses the control differential equation to calculate the lighting control solution equation based on the collected data. The response analysis module analyzes the lighting response of the target at different positions based on the results of these equations and selects the position with the largest response value. Finally, the efficiency and energy saving analysis module calculates the lighting efficiency and energy saving effect of the light group based on the maximum lighting response and other related parameters.

[0083] Preferably, in order to improve the performance and flexibility of the management device, the functions and operation steps of each module can be further refined. For example, the layout module can integrate more sensors and actuators to support more complex lamp group configurations. The data acquisition module can adopt higher-precision radar technology to improve the accuracy of detection data. The control equation solving module can adopt more advanced algorithms, such as numerical optimization methods, to improve the solving speed and accuracy. The response analysis module can introduce machine learning technology to automatically identify and predict the lighting response of the target. The efficiency and energy-saving analysis module can integrate more environmental parameters, such as temperature and humidity, to more comprehensively evaluate the energy-saving effect. As an alternative, wireless communication technology can be considered to remotely monitor and manage lamp groups to improve the flexibility and scalability of the system.
