[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] like Figure 1 The diagram shows a flowchart of an interactive control method for a solar-powered sign according to an embodiment of the present invention. The solar-powered sign is installed on a support device and includes a solar panel, a light-emitting housing, and a traffic radar. The method includes: The light-emitting enclosure includes an enclosure 1, an mounting plate 3 fixedly installed inside the enclosure 1, an energy storage module 2 and a control circuit board fixedly installed on the mounting plate 3, multiple LED beads 10 fixedly installed on the control circuit board, a reflector 9 provided inside the enclosure 1, multiple reflective cavities provided on the reflector 9, the LED beads 10 located inside the reflective cavities, a guide assembly fixedly installed on the reflector 9, a spring 15 provided around the guide assembly, an electromagnet 13 fixedly installed on the reflector 9, a magnetic block 14 fixedly installed on the mounting plate 3, a sliding groove 11 provided inside the enclosure 1, a set of sliding seats 12 slidably arranged in the sliding groove 11, a set of refracting mirrors 8 rotatably installed on the sliding seats 12, two sets of swing adjustment components installed on the refracting mirrors 8, the swing adjustment components are used to change the distance and angle between the plane where the refracting mirrors 8 and the reflector 9 are located.

[0020] The S100 uses traffic radar to identify and locate vehicles in the lane, determine the position and distance of each vehicle within the monitoring range, and generate radar monitoring information.

[0021] In this step, traffic radar is used to identify and locate vehicles in the lanes. The traffic radar used is an 80GHz traffic radar, such as the MWR300 model. The traffic radar can detect vehicles in 4-6 lanes at the same time and has both detection and tracking capabilities. It has extremely low power consumption, less than 4W. The traffic radar determines the position of all vehicles within the detection range and identifies the vehicles. During the operation of the traffic radar, radar monitoring information is generated in real time.

[0022] S200 generates position prediction information for each vehicle based on radar monitoring information, and determines vehicle distribution data at various future times based on the position prediction information.

[0023] In this step, position prediction information for each vehicle is generated based on radar monitoring information. The radar monitoring information records the position of each vehicle at various historical moments. For example, a vehicle is at position A at time t0 and at position B at time t1, thus forming the historical movement trajectory of the vehicle. Based on the vehicle's movement trajectory, the vehicle's speed can be determined, and the predicted position of the vehicle in a short period of time in the future can be predicted to generate position prediction information. Each vehicle corresponds to a set of position prediction information. Based on the position prediction information, the position of each vehicle within the monitoring range at a certain time in the future can be determined, which is the vehicle distribution data.

[0024] S300 generates an illumination range adjustment curve and an illumination position adjustment curve based on vehicle distribution data, wherein the illumination range covers all vehicles.

[0025] In this step, an illumination range adjustment curve and an illumination position adjustment curve are generated based on vehicle distribution data. A set of vehicle distribution data corresponds to the vehicle distribution in the monitoring area at a certain time. In order to make effective use of the light of the solar sign, its irradiance range is controlled so that it covers all vehicles with the minimum area, that is, the minimum illumination range under the vehicle distribution data is obtained. Thus, the minimum illumination range corresponding to different times is obtained. The center of the minimum illumination range is the illumination position. Interpolation is used to supplement adjacent minimum illumination ranges, thereby generating continuous illumination range adjustment curves and illumination position adjustment curves.

[0026] The S400 controls the light emission of the light-emitting box based on the illumination range adjustment curve and the illumination position adjustment curve, and adjusts the illumination direction and illumination range of the light.

[0027] In this step, the light-emitting box is controlled to emit light based on the illumination range adjustment curve and the illumination position adjustment curve. The light-emitting box can adjust the illumination direction and illumination range of all the lamp beads as needed, so that the light of each lamp bead can be seen by the driver within the illumination range. The light of the lamp beads is concentrated within the illumination range, so it can work with lower illumination power and achieve the illumination following effect, and can continuously remind the driver.

[0028] In this embodiment, the illumination range is adjusted primarily by adjusting the position of the reflector 9. The entire solar-powered sign generates electricity through solar panels, which is stored in the energy storage module 2. A light sensor is installed on the housing 1. When the light intensity is lower than a preset value, illumination begins. At this time, the traffic radar is activated to sense the position of each vehicle in the lane, outputting illumination range adjustment curves and illumination position adjustment curves. Based on the size of the illumination range, the electromagnet 13 is energized. After being energized, the electromagnet 13 generates a magnetic field, which repels the magnetic block 14, thus changing the distance between the electromagnet 13 and the magnetic block 14. During this process, the guiding component guides the electromagnet 13, ensuring it moves only in a straight line. The reflector 9 is fixed to the electromagnet 13; therefore, when the electromagnet 13 moves, it will cause the reflector 9 to move synchronously. The LED beads 10 are fixed to the circuit board, and their position remains unchanged. Thus, as the reflector 9 moves, the distance between the inner wall of the reflective cavity and the LED beads 10 changes. The closer the LED beads 10 are to the inner wall of the reflective cavity, the larger the coverage area of ​​the light emitted by the LED beads 10 after reflection. Therefore, by adjusting the distance between the LED beads 10 and the inner wall of the reflective cavity according to the illumination area, the desired illumination can be achieved. The size of the illumination range is adjusted by changing the current of electromagnet 13, thereby generating magnetic fields of different intensities. This balances the magnetic force between electromagnet 13 and magnetic block 14 with the elastic force of spring 15, resulting in the desired illumination range. When adjusting the illumination position, two sets of swing adjustment components are moved synchronously, causing the refracting mirror 8 to deflect and translate relative to the plane of reflector 9. The swing adjustment components include a micro motor 4, a screw 6 rotatably mounted on the inner wall of housing 1, and a drive block 5 mounted on the screw 6. The screw 6 drives the drive block 5 to translate along the axis, while the micro motor 4 drives the screw 6 to rotate. A drive block 5 is rotatably mounted on the drive block 5. The clamping base 7 and the refracting mirror 8 are located between two sets of clamping bases 7. The clamping base 7 can slide relative to the refracting mirror 8. Two sets of micro motors 4 can drive the two sets of clamping bases 7 to translate. When the two move synchronously, the refracting mirror 8 will translate relative to the reflector 9. When the two move at different distances and in different directions, the refracting mirror 8 will deflect relative to the reflector 9. The refracting mirror 8 is used to guide the light to refract. When the refracting mirror 8 is tilted, the incident angle changes, while the refraction angle remains unchanged. Therefore, the direction of light emission also changes. By changing the position and angle of the refracting mirror 8, the light illumination position of each LED bead 10 can be adjusted.

[0029] like Figure 2 As shown, in a preferred embodiment of the present invention, the step of generating position prediction information for each vehicle based on radar monitoring information, and determining vehicle distribution data at future times based on the position prediction information, includes: S201, acquire radar monitoring information, and determine the historical location of each vehicle within the monitoring range based on the radar monitoring information.

[0030] In this step, the traffic radar scans the surrounding environment. Each scan generates a frame of point cloud data. Each frame contains multiple detection points, and each point contains distance, radial velocity, and azimuth. The target (i.e., vehicle) is identified through a clustering algorithm. The center point position, bounding box, and velocity vector of each target are calculated. Each target detected in the current frame is associated and matched with the target tracked in the previous frame. After a successful match, the target will obtain a unique tracking ID.

[0031] S202, generate the historical motion trajectory of each vehicle based on the historical location of the vehicle, and generate the predicted motion trajectory based on the historical motion trajectory.

[0032] In this step, the obtained historical location points are connected in chronological order to form the historical motion trajectory of the vehicle. Based on the historical trajectory of each vehicle, a set of predicted motion trajectories is generated. The predicted motion trajectory is a time-continuous path, that is, a predicted motion trajectory that starts from the current moment and ends at a certain point in the future (such as 5 seconds later), which is used to represent a series of predicted states at future moments.

[0033] S203, extract the predicted motion trajectory of each vehicle, determine the vehicle position at each future time based on the preset time step, and obtain vehicle distribution data.

[0034] In this step, the predicted trajectory is a continuous curve. A fixed time step is set, Δt = 0.5 seconds. Sampling is performed along the continuous predicted trajectory of each vehicle according to this time step to calculate the future position. For each future discrete time point, such as T+0.5s, T+1.0s, T+1.5s ... T+5.0s, the predicted position of each vehicle at that precise time is calculated based on the predicted trajectory. The predicted positions of all vehicles at the same predicted time are summarized to obtain the vehicle distribution data.

[0035] like Figure 3 As shown, in a preferred embodiment of the present invention, the step of generating an illumination range adjustment curve and an illumination position adjustment curve based on vehicle distribution data, wherein the illumination range covers all vehicles, includes: S301, extract vehicle distribution data corresponding to each time moment, determine the position of each vehicle at that time moment, and determine the minimum illumination range based on the position of the vehicle.

[0036] In this step, vehicle distribution data corresponding to each time point is extracted. Each prediction time point corresponds to a set of vehicle distribution data. The vehicle distribution data is used to record the predicted position of each vehicle at that prediction time. The minimum illumination range is a rectangular area. The length of the side of the rectangular area parallel to the lane is the first side length, and the length of the side of the rectangular area perpendicular to the lane is the second side length. The first side length is greater than the distance L between the front of the vehicle and the parking space of the rearmost vehicle. For example, if the first side length is 1.2L, the second side length is greater than the total width B of all lanes. For example, if the second side length is 1.2B, then the minimum illumination range is 1.2B*1.2L.

[0037] S302, determine the irradiation position at each moment based on the location of the center of the minimum irradiation range.

[0038] In this step, the illumination position at each moment is determined based on the location of the center of the minimum illumination range. The minimum illumination range is a rectangle, and the intersection of the diagonals is determined. This intersection is used as the illumination position corresponding to the minimum illumination range.

[0039] S303 performs interpolation based on adjacent minimum irradiation ranges and irradiation positions, and outputs continuous irradiation range adjustment curves and irradiation position adjustment curves.

[0040] In this step, interpolation is performed based on adjacent minimum illumination ranges and illumination positions. For example, if the prediction time interval corresponding to adjacent minimum illumination ranges is 0.5 seconds, that is, the minimum illumination range corresponding to time A1 is S1, the illumination range corresponding to time A2 is S2, and the illumination range corresponding to time A3 is S3. Using a smooth interpolation method, multiple predicted minimum illumination ranges and illumination positions are inserted between A1 and A2, and between A2 and A3, to output continuous illumination range adjustment curves and illumination position adjustment curves.

[0041] like Figure 4 As shown, in a preferred embodiment of the present invention, the step of controlling the light-emitting box to emit light based on the illumination range adjustment curve and the illumination position adjustment curve, and adjusting the illumination direction and illumination range of the light, includes: S401, based on the illumination range curve, continuously adjusts the radiation range of a single light source inside the light-emitting box so that the radiation range covers the corresponding illumination range.

[0042] In this step, the radiation range of a single light source inside the light-emitting box is adjusted based on the continuous adjustment curve of the illumination range curve. The illumination range curve is continuously sampled, and the sampling frequency is determined according to the endurance management strategy. When the energy storage module's power is higher than the threshold, a higher sampling frequency is used, i.e., the sampling interval is reduced. Conversely, the sampling frequency is reduced to reduce energy consumption. The illumination range corresponding to that moment is determined based on the sampled data.

[0043] S402, extract the irradiation position corresponding to each radiation range based on the irradiation position curve, and determine the irradiation angle based on the irradiation position.

[0044] In this step, the irradiation position corresponding to each radiation range is extracted based on the irradiation position curve. The corresponding irradiation position is determined according to the extracted irradiation range. The required irradiation angle is calculated based on the irradiation position and the installation position of the solar sign.

[0045] S403 controls the illumination direction of the light source based on the illumination angle adjustment, and controls the illumination direction of the light emitted by each light source.

[0046] In this step, the illumination direction of the light source is controlled based on the illumination angle adjustment to control the light-emitting box. The control is divided into two parts: the first part is to adjust the illumination range, and the second part is to adjust the illumination position. By adjusting the illumination range and the illumination position, the illumination range is always able to cover all vehicles within the monitoring range. The working power of the LED beads 10 is adjusted according to the size of the illumination range and the distance of the illumination position. The larger the illumination range, the greater the working power of the LED beads 10, and vice versa. The farther the illumination position, the greater the lighting power is used to achieve the purpose of energy saving. When there are no vehicles in the monitoring area, the maximum illumination range is used and the working power of the LED beads 10 is reduced, or the LED beads 10 is stopped from working. The LED beads 10 are only turned on again when the traffic radar is working and the traffic radar detects a vehicle.

The vehicle distribution prediction unit is used to extract the predicted motion trajectory of each vehicle, determine the vehicle position at each future time based on a preset time step, and obtain vehicle distribution data.

[0050] The control information generation module 300 is used to generate an illumination range adjustment curve and an illumination position adjustment curve based on vehicle distribution data, wherein the illumination range covers all vehicles.

[0051] The control information generation module 300 includes: The illumination range calculation unit is used to extract vehicle distribution data at each time, determine the position of each vehicle at that time, and determine the minimum illumination range based on the position of the vehicle. The illumination position calculation unit is used to determine the illumination position at each moment based on the location of the center of the minimum illumination range. The curve generation unit is used to perform interpolation based on adjacent minimum irradiation ranges and irradiation positions, and output continuous irradiation range adjustment curves and irradiation position adjustment curves.

[0052] The dynamic adjustment module 400 is used to control the light emission of the light-emitting box based on the irradiation range adjustment curve and the irradiation position adjustment curve, and to adjust the irradiation direction and irradiation range of the light.

[0053] The dynamic adjustment module 400 includes: The range adjustment unit is used to adjust the radiation range of a single light source in the light-emitting box based on the continuous adjustment curve of the illumination range curve, so that the radiation range covers the corresponding illumination range.
