Description

Technical Field

[0001] The invention discloses a solar craft control system, belonging to the field of solar control systems. Background Art

[0002] Solar handicrafts are products that use solar energy to display art. The core of solar handicrafts is to use solar power generation groups to convert natural light energy into electrical energy to supplement the energy for the dynamic display of handicrafts. This not only conforms to the concept of environmental protection, but also can enhance the display effect through light and shadow and dynamic changes. It is widely used in furniture decoration, commercial display, science education and other scenarios.

[0003] Existing solar-powered crafts are mostly fixed in an integrated form, where the solar power generation module and the display unit are integrated into an inseparable whole and fixed in a specific location. This design prevents the crafts from adjusting their posture and position according to environmental changes, and can easily lead to visual fatigue after long-term display. Furthermore, their functions are often triggered manually, lacking active interaction with the environment. This makes it difficult to form dynamic feedback between the observer and the craft, significantly reducing its appeal.

[0004] A new solution is now proposed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a solar craft control system in order to solve the above problems.

[0006] The present invention achieves the above-mentioned purpose through the following technical solutions, a solar craft control system, comprising: Energy acquisition components and display components. The energy acquisition component adopts an animal-shaped design and includes the following modules: The mobile module is the base of the energy acquisition component and has movable tracks or wheels. It moves by receiving signals from the central processing module through independent dual motors. The light-seeking module is installed on the mobile module and can scan the surrounding environment 360 degrees. It has the ability to identify light sources through a photosensitive chip. It is used to determine the light intensity based on the external brightness, automatically mark the light intensity ranking, and send it to the central processing module; The sound detection module is installed on the mobile module and has a microphone and a sound wave sensor. It can receive sound waves, analyze the sound wave content, identify non-environmental sound waves, and send them to the central processing module; The central processing module is installed on the mobile module, uses the computer CPU for information processing, receives signals from the light-seeking module and the sound detection module, and makes corresponding judgments based on the signals. After the judgment is completed, the judgment is based on the following: confirming the light gathering point with the shortest straight-line distance, then analyzing the obstacles in the straight line, and cutting the obstacles with the straight line. After cutting, compare the distance between the two ends of the obstacle cut to the straight line, select the side with the shortest length as the detour point, and then connect the detour point as the end point, and use the connection line as the movement trajectory of the mobile module, and finally send the execution command to the mobile module; The solar module is installed on the top of the mobile module and has a solar panel that can receive light energy to generate electricity; The positioning module is installed on the mobile module and has a positioning function. It can record its own movement trajectory and upload it to the central processing module for retraction according to the movement trajectory. The display components include: The fixed display module adopts the shape of the home of the animal corresponding to the energy acquisition component, is fixed in a preset position, and is provided with a promotional pattern, and is mainly used for external display.

[0007] Preferably, both the energy acquisition component and the display component include: The energy storage module is installed inside the mobile module and the fixed display module and uses a battery pack to store electrical energy; The power transmission module is divided into a sub-kit and a mother-child kit, wherein the sub-kit is installed on the mobile module and the mother-child kit is installed on the fixed display module. The sub-kit has the function of transmitting power to the mother-child kit in one direction.

[0008] Preferably, the light-seeking module uses a visual recognition camera and a pan-tilt head that drives the camera to rotate 360 ​​degrees. It identifies the surroundings through the internal photosensitive chip of the vision, marks the area where the reflected light is concentrated, and sends the regional environmental information to the central processing module. The central processing module analyzes the optimal path based on the reflective area and environmental information, and then sends the movement information to the mobile module.

[0009] Preferably, it also includes a charging module, which is divided into a passive charging module and an active charging module. The passive charging module is installed on the mobile module and connected in parallel with the sub-kit, and is used to monitor the internal electric energy of the energy storage module and send a normal state or power-deficient state signal to the central processing module according to the electric energy reserve. One end of the active charging module is connected to the power supply, and the active charging module has a locator, which will continuously send position signals to the passive charging module.

[0010] Preferably, the normal state is marked as the default mode, the power-deficient state is marked as the highest action instruction, and the central processing module needs to interrupt other signal actions when receiving the power-deficient state signal, and execute the action of the passive charging module approaching the active charging module to charge.

[0011] Preferably, the sound detection module detects non-environmental sounds and identifies three types of signals: no signal, far signal and near signal, and sends the three signals to the central processing module. The central processing module makes the following decisions based on the three signals: when no signal is received, no action is taken; when a far signal is received, the mobile module remains silent, while the light-seeking module quickly scans the surrounding terrain, searches for a hidden spot and sends the location of the hidden spot to the central processing module; when a near signal is detected, the mobile module drives at full speed and quickly moves to the hidden spot.

[0012] Preferably, it also includes a sound module. When the sound detection module does not detect a signal, it is marked as no signal. At this time, the sound module plays a pre-recorded cheerful sound. When the sound detection module detects a distant signal, the volume of the sound module gradually decreases and finally disappears. When the sound detection module detects a near signal, the sound module plays a pre-recorded urgent and panic sound.

[0013] Preferably, an AI model with an optimization algorithm for enhancing autonomous learning capabilities is added to the internal algorithm of the central processing module.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: a fixed display module is set at a position that is easy to display, and the display components on the fixed display module will consume energy. At this time, an animal-like shape is formed by combining the remaining modules, and then the light source is found through the light-seeking module, and the animal moves to the light source. Then, the solar module absorbs light energy and converts it into electrical energy to charge the energy storage module. After charging to the threshold, the mobile module returns to the fixed display module according to the positioning record of the positioning module, and transmits electricity. Since external light will generate light of different intensities at different times and at different positions, the central processing module calculates the position with the best light energy at this time, and then moves there through the mobile module, forming a visual effect of animals going out to find food, and allowing observers to have an enhanced interactive exploration fun.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] like Figure 1 As shown, a solar craft control system includes: include: Energy acquisition components and display components. The energy acquisition component adopts an animal-shaped design and includes the following modules: The mobile module is the base of the energy acquisition component and has movable tracks or wheels. It moves by receiving signals from the central processing module through independent dual motors. The light-seeking module is installed on the mobile module and can scan the surrounding environment 360 degrees. It has the ability to identify light sources through a photosensitive chip. It is used to determine the light intensity based on the external brightness, automatically mark the light intensity ranking, and send it to the central processing module; The sound detection module is installed on the mobile module and has a microphone and a sound wave sensor. It can receive sound waves, analyze the sound wave content, identify non-environmental sound waves, and send them to the central processing module; The central processing module is installed on the mobile module, uses the computer CPU for information processing, receives signals from the light-seeking module and the sound detection module, and makes corresponding judgments based on the signals. After the judgment is completed, the judgment is based on the following: confirming the light gathering point with the shortest straight-line distance, then analyzing the obstacles in the straight line, and cutting the obstacles with the straight line. After cutting, compare the distance between the two ends of the obstacle cut to the straight line, select the side with the shortest length as the detour point, and then connect the detour point as the end point, and use the connection line as the movement trajectory of the mobile module, and finally send the execution command to the mobile module; The solar module is installed on the top of the mobile module and has a solar panel that can receive light energy to generate electricity; The positioning module is installed on the mobile module and has a positioning function. It can record its own movement trajectory and upload it to the central processing module for retraction according to the movement trajectory. The display components include: The fixed display module adopts the shape of the home of the animal corresponding to the energy acquisition component, is fixed in a preset position, and is provided with a promotional pattern, mainly used for external display; Among them, there are both energy acquisition components and display components: The energy storage module is installed inside the mobile module and the fixed display module and uses a battery pack to store electrical energy; The power transmission module is divided into a sub-kit and a mother-child kit, wherein the sub-kit is installed on the mobile module and the mother-child kit is installed on the fixed display module. The sub-kit has the function of transmitting power to the mother-child kit in one direction.

[0018] When this product is in use, the visual recognition module is driven to rotate by the pan-tilt system. The photosensitive chip on the visual recognition module marks the high-brightness area. At the same time, the visual recognition module picks up the terrain and transmits the terrain information to the central processing module. The built-in ORB-SLAM3 software and PCL cloud point library of the central processing module are used to quickly scan and establish a gridded terrain, which is stored in the central processing module for subsequent calls. After the terrain is established and the light zone is calibrated, the central processing module connects the position of the mobile module to the position of the nearest light zone according to the principle of proximity. After the connection is completed, it analyzes whether there is an obstacle in the connection. The obstacle is judged as follows: if it is greater than the maximum pass height of the mobile module, it is judged as an obstacle. At this time, there are two situations: Once there are no obstacles, a movement command is issued to the mobile module; If there is an obstacle in the middle, the intervention algorithm is used: the point of contact between the connecting line and the obstacle is used as the dividing point, and then the obstacle is divided. Then the maximum distance L from the dividing point to both sides of the obstacle is calculated. 左 and L 右 , then compare L 左 and L 右 , take the endpoint with the smaller value as the detour point, then connect the line again, and calculate the shortest moving distance several times. If the overall moving distance after adding the detour point is greater than the distance to another light zone in a straight line, then the other light zone is also substituted into the calculation. Finally, take the shortest moving distance as the moving path and send it to the mobile module to move. After the energy acquisition component moves to the light area, the solar panel charges the energy storage module under the illumination of light. When the power in the energy storage module is charged to the preset value, the central processing module sends a return instruction to the mobile module and at the same time mobilizes the movement trajectory recorded in the positioning module to make the mobile module move in the opposite direction to prompt the energy acquisition component to return to the display module. In this way, the charging process of the handicraft is completed. However, if a new obstacle appears on the return path, the algorithm will be intervened again to avoid the obstacle to ensure normal return.

[0019] This product also includes a charging module, which is divided into a passive charging module and an active charging module. The passive charging module is installed on the mobile module and connected in parallel with the sub-kit. It is used to monitor the internal electrical energy of the energy storage module and send a normal state or power-deficient state signal to the central processing module according to the electrical energy reserve. One end of the active charging module is connected to the power supply. At the same time, the active charging module has a locator and will continuously send position signals to the passive charging module. The normal state is marked as the default mode and the power-deficient state is marked as the highest behavior instruction. When the central processing module receives the power-deficient state signal, it needs to interrupt other signal actions and execute the action of the passive charging module approaching the active charging module to charge. This setting has the highest priority to ensure that when the energy acquisition component has an electrical energy lower than the threshold, it can directly charge the energy through an external power supply to avoid the energy acquisition component stopping due to having nowhere to charge.

[0020] It also includes a sound module, which uses a ring-shaped multi-channel microphone array and has the following built-in core algorithms: Sound source localization uses the TDOA algorithm to calculate the time difference ∆t between the same sound reaching different microphones and the distance d between the microphones using the formula: sinθ = Δt * v / d, where v is the speed of sound and the direction of the animal's head camouflaged as the acquisition component is the normal. θ is the direction of the sound source. Then, using the beamforming algorithm and the frequency offset Δf, the distance S from the sound source to the energy acquisition component is calculated. Adaptive noise reduction uses the LMS algorithm to learn ambient sounds in real time and subtract the background sounds from the sounds captured by the microphone to highlight the target sound and locate the source of the prominent target sound. In the absence of a prominent target sound, it is determined that there is no signal. The LMS algorithm is as follows: the surrounding sound wave signal in the device is extracted, recorded every 5 seconds, and then the signal bands in the two recordings are compared. If the signal bands are close, it is marked as ambient sound X. At the same time, the ambient sound of the previous group is deleted, and then the LMS weight is set. The output Y of the filtered ambient sound X is adjusted in real time. Then, the mixed signal D formed by extracting the sound received by the microphone and filtering it is obtained. At this time, the prominent target sound signal E can be obtained through DY. The target sound signal is then judged, the sensitivity setting Z is calibrated, and the size of E and Z is compared. When E≥Z, it is determined that there is a target object.

[0021] When the signals satisfying ΔS / Δt<0 and Δf>0 are both satisfied, it is determined that an object is approaching. At this time, the distance S from the sound source to the energy acquisition component is compared with the preset distance S 阈 , when S / S 阈 When S / S is less than 1, it is judged as a near signal and the near signal information is sent to the central processing module. The central processing module instructs the mobile module to move to a hidden place. The hidden place here is a dim light area, which is marked by the light-seeking module according to the light intensity.阈 When >1, it is judged as a far signal.

[0022] When the sound module receives the no-signal judgment from the sound detection module, the sound module plays a pre-recorded cheerful sound. When the sound detection module sends a far signal, the volume of the sound module gradually decreases and finally disappears. When the sound detection module detects a near signal, the sound module plays a pre-recorded urgent and panic sound.

[0023] This system utilizes a combination of a mobile module, a light-seeking module, a sound detection module, a central processing module, a solar module, an energy storage module, a positioning module and an electric energy transmission module to form a whole, and then the appearance is designed to form the appearance of a small animal, and the fixed display module is set to the appearance of a small animal's home. When the internal power of the fixed display module is consumed and the power of the fixed display module is reduced, other modules disguised as small animals can go out to collect electricity, thereby achieving the visual effect of small animals going out to forage, and there will be a pause when there is an abnormal sound in the outside world, to imitate the effect of small animals going out to forage being alert to the outside world at all times, and a visual effect of fleeing will be formed when the sound approaches, further achieving the mimicry effect, and further by playing pre-recorded sounds, the sound effects of different psychological fluctuations of small animals at different times can be better imitated, so as to reversely deduce the state of the small animals at this time through the sound effects, thereby better achieving the interactive effect.

[0024] The AI ​​deep learning CPU built-in algorithm logic includes: dynamic environmental perception, obstacle detection and avoidance, path optimality judgment, computing efficiency and corresponding balance; The dynamic perception of the environment adopts grid modeling, uses visual recognition to identify the environment, determines the passable and impassable areas, and marks the grid into three forms: passable, impassable and uncertain. The impassable and uncertain are judged as follows: impassable areas with a continuous transition with the passable area are marked as impassable areas, and impassable areas with abrupt small areas that are impassable with the passable area are judged as uncertain. The density of the grid in the impassable area is reduced, that is, the grid becomes larger, and the uncertain needs to be updated and revised in subsequent perception, and then the grid terrain is established, and the grid terrain is digitized and transmitted to the CPU; A reward mechanism is established, and collision penalties are used to reinforce the strategy of avoiding obstacles during the learning process. A reward function is designed in combination with distance changes to achieve an optimization algorithm. The algorithm adopts the following approach: when the distance to the obstacle is less than the safety threshold, the penalty is triggered immediately, and the penalty is increased after touching the obstacle. When the number of collisions is too many, the highest level of penalty is imposed and the path is replanned. At the same time, the penalty is memorized and continued. When the same position is punished multiple times, the previous penalties are superimposed. Rewards are given after a successful passage. The reward is based on the better solution of the path, that is, the reward is given for shortening the total distance, and the greater the shortened distance, the higher the reward.

[0025] The DQN algorithm is used to estimate the action value through the grid, and then combine the previously unpunished strategy to further improve the calculation speed to achieve the optimality of the path judgment; the grids are numbered, and each grid represents the current position, that is, each position corresponds to 4 actions, incorrect actions will be punished, and correct actions will be rewarded. At the same time, the action score is estimated, that is, the direction close to the destination is rewarded, the closer to the destination, the more reward points, and the optimal solution reward is established. That is, the total travel path is less than the original path, and a higher reward will be obtained. At the same time, an experience library is established to store the paths after the reward is obtained, and the paths after the reward are arranged by score so that they can be retrieved when the experience is reused; the experience update deletes and updates the experience that has changed the decision during the experience retrieval process.

[0026] Further model optimization: Introducing the LSTM time series model to process dynamically changing environmental data, enhancing the model's robustness to environmental changes, optimizing the reward function, factoring in path smoothness and energy consumption, and using a quantized straight line composition with smoothed grid lines to reduce computational overhead. Simultaneously, establishing a ratio between computational load and movement speed, achieving an inverse proportional binding where less computational load equals faster movement speed, thus increasing operational speed.
