[0028] As shown in Figure 1 A solar art control system comprises:

[0029] comprises:

[0030] An energy acquisition component and a display component, wherein the energy acquisition component adopts an animal-shaped design and comprises the following modules:

[0031] A moving module, which is a base of the energy acquisition component and has movable tracks or wheels and moves by receiving signals from a central processing module through independent double motors;

[0032] A light-seeking module, which is installed on the moving module, can scan the surrounding environment at 360 degrees, and is a module with light source recognition capability through a photosensitive chip, and is used to determine the light intensity by the external brightness, automatically mark the light intensity ranking, and then send it to the central processing module;

[0033] A sound detection module, which is installed on the moving module and has a microphone and a sound wave sensor, can receive sound waves and analyze the sound wave content, identify non-environmental sound waves and send them to the central processing module;

[0034] A central processing module, which is installed on the moving module, uses a computer CPU for information processing, receives signals from the light-seeking module and the sound detection module, and makes corresponding judgments according to the signals, and after the judgment is completed, the judgment basis is to confirm the light gathering point with the shortest straight line distance, then analyze the obstacles in the straight line, and cut the obstacles with the straight line, compare the length of the two ends of the cut obstacles to the length of the straight line, select the side with the shortest length as the bypass point, then connect the bypass point as the moving track of the moving module, and finally send the execution command to the moving module;

[0035] A solar module, which is installed on the top of the moving module and has a solar panel, can receive light energy to generate electric energy;

[0036] The positioning module is installed on the moving module and has a positioning function, and can record the moving track and upload it to the central processing module, so as to perform a rollback action according to the moving track.

[0037] The display component includes:

[0038] The fixed display module adopts the shape of the home of the corresponding animal of the energy acquisition component, is fixed at a preset position, and is provided with a propaganda pattern, and is mainly used for display.

[0039] The energy acquisition component and the display component both include:

[0040] The energy storage module is installed inside the moving module and the fixed display module, and adopts a battery pack to store electric energy.

[0041] The electric energy transmission module is divided into a sub-assembly and a parent assembly, the sub-assembly is installed on the moving module, the parent assembly is installed on the fixed display module, and the sub-assembly has the function of transmitting electric power to the parent assembly in one direction.

[0042] When the product is used, the visual recognition module is driven to rotate by the holder, the photosensitive chip on the visual recognition module marks the high-brightness area, the visual recognition module picks up the terrain, and the terrain information is transmitted to the central processing module, the ORB-SLAM3 software and the PCL cloud point library in the central processing module are cooperated to quickly scan and establish a grid terrain, and the grid terrain is stored in the central processing module for subsequent calling, after the terrain is established and the light area is calibrated, according to the nearest principle, the central processing module connects the position of the moving module to the position of the nearest light area, analyzes whether there is an obstacle in the connection line, and the determination of the obstacle is that the maximum passing height of the moving module is greater than the obstacle, that is, the obstacle is determined, at this time, two situations will occur:

[0043] One is no obstacle, and a moving command is issued to the moving module;

[0044] Two is that there is an obstacle in the middle, and the algorithm is intervened: taking the contact point of the connection line and the obstacle as a dividing point, then cutting the obstacle, then calculating the maximum distance L 左 and L 右 on both sides of the dividing point to the obstacle, then comparing L 左 and L 右 , taking the smaller one as the bypass point, then connecting again, and calculating the shortest moving distance after several times, and when the bypass point is added, the overall moving distance is greater than the distance of the straight line to another light area, then another light area is also substituted into the calculation, and finally the shortest moving distance is taken as the moving path, and is sent to the moving module to move the moving module;

[0045] After the energy acquisition component moves to the light area, the solar power panel charges the energy storage module under the illumination of light. When the electricity in the energy storage module is charged to the preset value, the central processing module sends a return instruction to the moving module, and mobilizes the recorded moving track in the positioning module to make the moving module move reversely to return to the display module. Thus, the charging process of the artwork is completed. However, when a new obstacle appears in the return path, the algorithm is intervened again to avoid the obstacle, thereby ensuring normal return.

[0046] The 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 moving module and is connected in parallel with the sub-kit, is used for monitoring the internal electric energy of the energy storage module, and sends a signal of normal state or power shortage state to the central processing module according to the energy storage amount. One end of the active charging module is connected to the power supply, and the active charging module has a positioner, which continuously sends a position signal to the passive charging module. The normal state is marked as a default mode, and the power shortage state is marked as the highest behavior instruction. The central processing module needs to interrupt other signal actions when receiving the power shortage state signal, and executes the action of the passive charging module approaching the active charging module to charge. This setting is the highest priority, which ensures that the energy acquisition component can be directly charged by the external power supply when the electric energy is lower than the threshold value, and avoids the energy acquisition component from stopping without charging.

[0047] The sound module is also included, which is arranged in a ring shape through a multi-channel microphone array, and the built-in core algorithm is as follows:

[0048] Sound source positioning is achieved through the TDOA algorithm through the time difference At of the same sound reaching different microphones and the distance d between the microphones through the formula: sinθ=At*v / d, wherein v is the sound speed. The direction of the sound source is obtained by taking the animal head of the acquisition component as the normal line. Then, the distance S from the sound emitting point to the energy acquisition component is obtained through the beam forming algorithm and the frequency offset Af.

[0049] Adaptive noise reduction, by using LMS algorithm to learn the environment sound in real time, and subtract the background environment sound from the sound obtained from the microphone, to highlight the target sound to highlight the target sound source positioning, in the absence of prominent target sound is determined to be no signal; wherein the LMS algorithm is: extraction device in the surrounding sound signal, every 5 seconds for recording, then compare the signal band in two records, signal band close to the environment sound X, while deleting the environment sound in the first group, then set the LMS weight, through the real-time adjustment of the environment sound X after filtering the output Y, then extract the sound received by the microphone and form the mixed signal D after filtering, at this time through D-Y can get the protruding target sound signal E, then determine the target sound signal, set the sensitivity Z, compare the size of E and Z, when E≥Z, it is determined to have target.

[0050] Whether or not, when the signal satisfies ΔS / Δt<0 and Δf>0 at the same time, it is determined that the object is close, 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 <1 is determined as a near signal, and the near signal information is sent to the central processing module, the central processing module commands the moving module to transfer to the hiding place, the hiding place here is the dim light area, which is marked by the light seeking module according to the light intensity; when S / S 阈 >1 is determined as a far signal.

[0051] When the sound module receives the no signal determination issued by the sound detection module, the sound module plays the pre-recorded cheerful sound at this time, the sound module volume gradually decreases and finally disappears when the sound detection module detects a far signal, the sound module plays the pre-recorded urgent and nervous sound when the sound detection module detects a near signal.

[0052] The system uses the combination of the moving module, the light seeking module, the sound detection module, the central processing module, the solar module, the energy storage module, the positioning module and the electric energy transmission module to form a whole, and then the appearance is designed to form the appearance of a small animal. The fixed display module is set to the appearance of a small animal's home. When the internal electric energy of the fixed display module is consumed, the electric energy of the fixed display module decreases. At this time, the other modules disguised as small animals can go out to collect electric energy, so as to realize the visual effect of small animals going out to forage, and pause after abnormal sound appears in the outside world to imitate the effect of small animals going out to forage at all times. After the sound approaches, the visual effect of fleeing is formed, further realizing the mimicry effect, and further playing the pre-recorded sound to better imitate the sound effect of small animals producing different psychological fluctuations at different times, so as to obtain the state of small animals at this time through sound effect, and better realize the interactive effect.

[0053] The CPU built-in algorithm logic of AI deep learning is: environmental dynamic perception, obstacle detection and avoidance, path optimality judgment, and corresponding balance of calculation efficiency.

[0054] The environmental dynamic perception adopts a grid model, uses visual recognition to determine passable and impassable areas, and marks the grid in three forms: passable, impassable, and uncertain. The judgment of impassable and uncertain is that the impassable marking with continuity transition to the passable area is determined as an impassable area, and the abrupt small area with the passable area is determined as uncertain. The grid density of the impassable area is reduced, i.e., the grid is enlarged, and the uncertain needs to be updated and revised in the subsequent perception. Then the grid terrain is established, and the grid terrain data is transmitted to the CPU.

[0055] A reward mechanism is established to strengthen the strategy of avoiding obstacles in the learning process by punishing collision behavior. A reward function is designed in combination with distance changes to optimize the algorithm. The algorithm is as follows: when the distance to the obstacle is less than the safety threshold, the punishment is triggered immediately; the punishment is increased after touching the obstacle; when the number of collisions is too high, the highest level of punishment is imposed and the path is re-planned. At the same time, the punishment is remembered and continued. When the same position is punished multiple times, the past punishments are superimposed. Rewards are given after successfully passing through. The reward is based on the more optimal solution of the path, i.e., the shorter the distance, the higher the reward.

[0056] The DQN algorithm is used to estimate the value of actions through the grid, and then the strategy of not being punished before is combined to further improve the operation speed to achieve path optimality judgment. The grid is numbered, and each cell represents the current position. Each position corresponds to four actions. The wrong action will be punished, and the correct action will be rewarded. At the same time, the estimated action score is calculated, i.e., the reward is given to the direction close to the destination, and the closer to the destination, the higher the reward score. At the same time, the optimal solution reward is established, i.e., the total path is shorter than the original path, and a higher reward will be obtained. An experience library is established to store the paths after rewards, and the paths after rewards are arranged in order of score to be retrieved when experience is reused. Experience updating deletes and updates the experience that changes the decision in the process of retrieving experience.

[0057] Further model optimization: introduce LSTM time series model to process dynamic environmental data, enhance the robustness of the model to environmental changes, optimize the reward function, consider path smoothness and energy consumption factors, grid line smooth segment quantization straight line composition, reduce retrieval operation, and at the same time establish the operation amount and moving speed ratio, bind in inverse proportion that the less the operation amount, the faster the moving speed, to increase the running speed.
