Description

Technical Field

[0001] This disclosure relates to the field of smart aquarium technology, and more specifically, to a mobile digital human ecological aquarium. Background Technology

[0002] With the development of smart homes and aquarium equipment, fish tanks are no longer just used as simple water containers, but are gradually evolving towards intelligent functions such as water quality monitoring, temperature regulation, automatic filtration, lighting adjustment, and remote control. Existing smart fish tanks typically monitor and regulate the aquarium environment by incorporating components such as temperature sensors, water quality sensors, filtration devices, heating devices, or oxygen supply devices, thereby reducing the difficulty of daily maintenance for users.

[0003] However, existing aquariums are typically fixed structures, and their overall weight is considerable when filled with water. When users need to change the water, clean the aquarium, adjust its placement, or change the viewing position, it often requires a significant amount of manpower, and their mobility is poor. Furthermore, the internal landscaping of traditional aquariums usually relies on real aquatic materials such as aquatic plants, artificial rocks, gravel, and backdrops. When users wish to change the viewing scene or adjust the aquarium's style, they need to purchase or disassemble internal components, which is not only cumbersome but can also easily disrupt the stability of the aquarium's ecosystem.

[0004] Furthermore, existing aquariums have limited ability to perceive the condition of fish and their surrounding environment. Users typically rely solely on visual observation of fish activity, making it difficult to promptly detect abnormal behavior, external lesions, or abnormal water parameters. When users are not near the aquarium, it is also difficult to obtain timely information such as water temperature, water quality, pH, dissolved oxygen, ammonia nitrogen levels, fish numbers, and activity levels. For users lacking professional aquarium breeding experience, it is often difficult to promptly identify the causes of abnormalities and take effective maintenance measures during fish farming and aquarium ecosystem maintenance. Summary of the Invention

[0023] Research has found that existing aquariums are typically fixed structures, and their overall weight is considerable when filled with water. When users need to change the water, clean the aquarium, adjust its placement, or change the viewing position, it often requires a significant amount of manpower, and their mobility is poor. Furthermore, the internal landscaping of traditional aquariums usually relies on real aquatic materials such as aquatic plants, artificial rocks, gravel, and backdrops. When users want to change the viewing scene or adjust the aquarium's style, they need to purchase or disassemble internal components, which is not only cumbersome but can also easily affect the stability of the aquarium's ecosystem.

[0024] Furthermore, existing aquariums have limited ability to perceive the condition of fish and their surrounding environment. Users typically rely solely on visual observation of fish activity, making it difficult to promptly detect abnormal behavior, external lesions, or abnormal water parameters. When users are not near the aquarium, it is also difficult to obtain timely information such as water temperature, water quality, pH, dissolved oxygen, ammonia nitrogen levels, fish numbers, and activity levels. For users lacking professional aquarium breeding experience, it is often difficult to promptly identify the causes of abnormalities and take effective maintenance measures during fish farming and aquarium ecosystem maintenance.

[0025] Based on the above research, this disclosure provides a mobile digital human ecological fish tank. By integrating a mobile base, a transparent display device, a digital human interaction system, an environmental sensing module, an ecological adjustment module, and a communication module into the main body of the fish tank, the fish tank can intelligently monitor, interactively display, ecologically adjust, and move its position according to the water condition, fish condition, lighting conditions, and indoor space environment. This improves the ease of use of the fish tank, enriches the viewing experience, helps users understand the condition of the fish and water in a timely manner, and provides maintenance suggestions or performs corresponding adjustment operations in abnormal situations, thereby enhancing the ecological maintenance effect, interactive experience, and intelligence level of the fish tank.

[0026] To facilitate understanding of this embodiment, a mobile digital human ecological fish tank disclosed in this disclosure will first be described in detail.

[0027] See Figures 1-2 As shown, Figure 1 This is one of the schematic diagrams of a mobile digital human ecological fish tank provided in this embodiment of the disclosure. Figure 2 This is a second schematic diagram of a mobile digital human ecological fish tank provided in an embodiment of this disclosure.

[0028] Specifically, this disclosure provides a mobile digital human ecological fish tank, which includes a fish tank body, a mobile base, a transparent display device, an environmental sensing module, an ecological regulation module, a control module, and a communication module.

[0029] The system comprises: a main aquarium body for housing water, fish, and the internal landscape; a movable base positioned beneath the main aquarium body for moving the aquarium body within the indoor space; a transparent display device located on at least one side of the main aquarium body for displaying a digital human image, interactive information, or virtual scenes while the user views the actual interior of the aquarium; an environmental sensing module for collecting environmental status data of the interior and exterior of the aquarium body; an ecological regulation module for regulating the ecological environment within the aquarium body according to control commands from the control module; a control module for analyzing environmental status data and controlling the movable base, transparent display device, and ecological regulation module to work collaboratively based on the analysis results; and a communication module for enabling data interaction between the mobile digital human ecological aquarium and the user terminal or server.

[0030] Here, the main body of the aquarium can be made of high-strength transparent materials, such as transparent acrylic, to ensure good light transmission and aesthetics. The overall shape of the aquarium main body can be square, rounded square, or irregularly shaped, depending on the usage scenario and appearance requirements. A cable management channel can be provided on the side of the aquarium main body to accommodate the connecting cables between the transparent display device, environmental sensing module, ecological regulation module, and control module, thereby reducing exposed cables and improving the overall appearance consistency and safety of use.

[0031] In some embodiments, the top of the aquarium body may include a first top region and a second top region. The first top region may be an electronic component mounting area, and the first top region is provided with an electronic component mounting sealing structure. The electronic component mounting sealing structure is used to accommodate, shield, or protect electronic components such as microphone arrays, cameras, top light sensor modules, controllers, communication modules, and cable interfaces. The electronic component mounting sealing structure remains closed under normal use to reduce the impact of moisture, water droplets, dust, or accidental external contact on the electronic components; when it is necessary to repair, inspect, replace, or maintain the circuit of the electronic components, the electronic component mounting sealing structure can be opened.

[0032] Here, the second top area serves as a daily operation area, equipped with a daily operation switch. This switch is used to activate the system when the user performs feeding, water changes, cleaning, adjusting the aquarium's internal landscape, or other routine maintenance. This effectively separates the electronic component maintenance area on the top of the aquarium from the user's daily operation area. Users do not need to open the sealed structure of the electronic components during feeding, water changes, or cleaning, thus improving the waterproof and moisture-proof reliability of the electronic components and reducing the risk of daily operations affecting the area where the electronic components are located.

[0033] In the embodiment shown in the accompanying drawings, one side of the top of the aquarium body can be configured as a sealed portion, corresponding to an electronic component mounting sealing structure; the other side of the top of the aquarium body can be configured as a switchable portion, corresponding to a daily operation switch structure. The sealed portion and the switchable portion can be arranged in sections along the width, length, or other directions of the aquarium body, and this application does not limit this arrangement.

[0034] The top of the aquarium can also be equipped with one or more of the following components: a filter, a temperature sensor, an oxygen supply system, a microphone array, a camera, and a top light sensor, in order to collect and adjust the internal ecological environment and user interaction status of the aquarium.

[0035] Furthermore, the mobile base is positioned below the main body of the aquarium and may include a chassis, a set of wheels, a drive motor, a bottom mainboard, and bottom sensors. The chassis supports the main body of the aquarium and the water within it. The wheels, driven by the drive motor, move forward, backward, turn, or stop. The bottom mainboard can connect to a control module to receive movement control commands from the control module and drive the wheels to move along a preset or user-specified route. The bottom sensors may include one or more of the following: a bottom light sensing module, a distance sensor, a collision sensor, a posture sensor, or a ground obstacle detection sensor. These sensors are used to collect environmental information around or below the mobile base to support obstacle avoidance, path planning, and safety control during movement.

[0036] Furthermore, the transparent display device can be fitted and installed on the front or other visible side of the aquarium body. The transparent display device can be a transparent screen used to display a moving digital human figure, aquarium status information, virtual backgrounds, fishkeeping tips, maintenance suggestions, or a user interface. Because the transparent display device has light-transmitting properties, users can see the digital human figure or virtual scene displayed on the transparent display device while viewing the real fish and landscape inside the aquarium, thus achieving a superimposed display of the real aquarium landscape and virtual digital content.

[0037] For example, transparent display devices can display underwater coral backgrounds, natural aquatic plant backgrounds, holiday-themed backgrounds, or other virtual scenes according to user selection. They can also use digital human figures to report water temperature, water quality, fish health status, or maintenance suggestions to users.

[0038] Furthermore, the environmental perception module may include a water sensing unit, a light sensing unit, an image acquisition unit, and an obstacle perception unit. The water sensing unit collects water quality data such as water temperature, water quality, pH, dissolved oxygen, and ammonia nitrogen levels within the aquarium. The light sensing unit may include a top light sensor module and a bottom light sensor module to collect light intensity data at different locations within the aquarium to determine if the lighting is suitable for fish or for the user's viewing. The image acquisition unit may include an internal fish tracking camera and an external space monitoring camera. The internal fish tracking camera collects images or videos of fish to identify their number, activity level, appearance, or abnormal behavior. The external space monitoring camera collects images of the indoor space to help create an indoor map, identify changes in furniture and objects, and detect moving obstacles. The obstacle perception unit collects information about obstacles along the movement path for the control module to assess obstacle avoidance and movement safety.

[0039] Furthermore, the ecological regulation module may include one or more of the following: a heating unit, an oxygenation unit, a filtration unit, a lighting unit, and an ambient lighting unit. The heating unit heats the aquarium water when the temperature is below the target range; the oxygenation unit supplies oxygen to the water when dissolved oxygen levels are insufficient; the filtration unit circulates and filters the water to maintain stable water quality; and the lighting unit or ambient lighting unit adjusts the lighting environment or displays an atmosphere within the aquarium. The ecological regulation module can be connected to the control module. When the control module determines that the aquarium's ecological environment is abnormal based on water condition data or fish condition data, the control module can control the corresponding ecological regulation module to perform operations such as heating, oxygenation, filtration, or lighting adjustment.

[0040] Furthermore, the control module can be located on top of the aquarium body, inside the movable base, or in the mounting cavity between the aquarium body and the movable base. The control module is connected to the movable base, the transparent display device, the environmental sensing module, the ecological regulation module, and the communication module. The control module receives environmental status data collected by the environmental sensing module and analyzes and processes this data to determine the water condition, fish condition, lighting condition, movement safety condition, and user interaction condition within the aquarium body. The control module also generates corresponding control commands based on the analysis results.

[0041] For example, when the water temperature, pH, dissolved oxygen, or ammonia nitrogen levels are abnormal, the control module can control the ecological regulation module to make corresponding adjustments; when the fish activity is abnormal or the fish show signs of disease, the control module can control the transparent display device to display digital human reminder information and push maintenance suggestions to the user terminal through the communication module; when the current lighting is unsuitable or the user needs to adjust the position of the aquarium, the control module can control the movable base to move the main body of the aquarium to the target position.

[0042] Furthermore, the communication module may include a wireless communication unit, which can establish a communication connection with the user terminal using Wi-Fi, Bluetooth, or other wireless communication methods. The user terminal can be a smartphone, tablet, smart speaker, or other smart home control device. Users can view the water temperature, water quality, number of fish, fish activity level, historical trend data, and equipment operating status within the aquarium through the user terminal. They can also send control commands to the control module through the user terminal to adjust the digital human figure or virtual scene displayed on the transparent display device, control the ecological regulation module to perform heating, oxygenation, filtration, or lighting adjustments, or control the movable base to move to a designated position.

[0043] It should be noted that the communication module can also communicate with the server to obtain fish farming knowledge, fish disease prevention and control knowledge, weather information or indoor lighting information to assist in judgment, and provide data support for the control module to generate maintenance suggestions, movement strategies and interactive content.

[0044] In some embodiments, the main body of the aquarium can be made of transparent acrylic material to ensure high structural strength and good light transmittance. The shape of the main body can be an irregularly shaped, rounded square structure, so that the aquarium can accommodate water and fish while also having a good aesthetic appeal. Cable routing channels can be provided on the sides of the main body, located in recessed areas on the left and right sides of the main body and covered by an external cover.

[0045] Here, the cables connecting the transparent display device, environmental sensing module, ecological regulation module, and control module can be routed within the cable management channel, thus avoiding exposed cables that could affect the aquarium's appearance and reducing the risk of cables getting damp, pulled, or accidentally bumped. A switchable sealing structure can be installed on the top of the aquarium body, allowing users to feed, change water, clean, inspect, or replace internal aquarium components. When closed, the sealing structure reduces water sloshing and the entry of external dust into the aquarium body, improving safety and stability during use.

[0046] In some embodiments, the environmental sensing module may include a water sensing unit, a light sensing unit, an image acquisition unit, and an obstacle sensing unit. The water sensing unit may be located inside the aquarium body or near the filter structure on top of the aquarium body, and is used to collect water state data such as water temperature, water quality, pH, dissolved oxygen, and ammonia nitrogen levels. The light sensing unit may include a top light sensing module and a bottom light sensing recognition module. The top light sensing module is used to collect the light intensity above or around the aquarium body, and the bottom light sensing recognition module is used to assist in recognizing changes in light near the movable base, thereby determining whether the current location of the aquarium meets the suitable lighting conditions for fish.

[0047] Here, the image acquisition unit can include an internal fish tracking camera and an external space monitoring camera. The internal fish tracking camera is used to acquire images of fish inside the aquarium to identify the number of fish, their activity level, and their appearance. The external space monitoring camera is used to acquire images of the indoor space to create an indoor space map, identify newly added furniture items, and obstacles in the movement path. The obstacle perception unit can be installed on the outside of the mobile base or the main body of the aquarium to collect information such as the distance to obstacles, the height of obstacles, the width of obstacles, or the slope of the ground in the movement path.

[0048] In some embodiments, the control module can create an indoor space map based on external space obstacle data collected by external space monitoring cameras and obstacle perception units. The indoor space map may include passable areas, impassable areas, areas where the target is frequently present, restricted access areas, viewing and lighting areas, and charging base areas. Upon initial use or when a new scene is introduced, the control module can control the movable base to move the aquarium body within the indoor space to obtain indoor layout information and determine the positions of walls, furniture, doors, windows, obstacles, and the charging base based on this information.

[0049] Users can manually mark indoor space maps using user terminals or transparent display devices. For example, they can mark areas where they want the fish tank to stay permanently, or restricted areas where entry is prohibited. The control module can update the indoor space map based on user markings, enabling the mobile digital human-shaped ecological fish tank to move and stay according to user preferences.

[0050] In some embodiments, since the aquarium body contains water, the impact of water sloshing on the overall stability needs to be considered when the movable base moves the aquarium body. The control module can determine the chassis attitude angle and the amplitude of water sloshing when the aquarium body passes over obstacles or sloping sections based on the obstacle height, slope, width, wheel track of the movable base, and the current water level of the aquarium body.

[0051] Specifically, if the control module determines that the current water level is too high or the slope of the obstacle is too steep, it can limit the moving speed of the mobile base or output a prompt message to the user to lower the water level. If the mobile base reaches a preset distance from the obstacle, the control module can control the mobile base to slow down in advance to reduce the amplitude of water surface sloshing when passing the obstacle. If the amplitude of water surface sloshing exceeds a preset sloshing threshold, the control module can control the mobile base to stop moving forward or perform a reverse movement, and replan the movement route, while outputting an abnormal movement prompt to the user through a transparent display device or user terminal. In this way, the risk of the aquarium body tipping over, overflowing, or violent water sloshing during the movement can be reduced.

[0052] In some embodiments, when the control module controls the movable base to move the aquarium body, it can limit not only the moving speed of the movable base but also its moving acceleration. Moving acceleration can include linear acceleration, deceleration, directional acceleration, and lateral acceleration due to changes in path curvature. Since the aquarium body contains water, the water surface is prone to significant sloshing when the movable base suddenly starts, decelerates, turns rapidly, or traverses bumpy sections. Therefore, the control module can limit the rate of change of the movable base's speed and directional acceleration based on the chassis attitude angle, the amplitude of water surface sloshing, the current water level, and information about obstacles along the path.

[0053] Specifically, when the control module detects obstacles or slopes ahead on the movement route, it can control the mobile base to enter a smooth deceleration state in advance, gradually reducing its speed according to preset acceleration limits, rather than abruptly decelerating when approaching obstacles. Furthermore, when the mobile base needs to change direction, the control module can prioritize using small-curvature turns to adjust the route, reducing lateral acceleration during the turn. If the control module detects that the liquid surface sloshing is close to or exceeds a preset sloshing threshold, it can further reduce the movement speed, reduce acceleration, stop moving, or replan the movement route. This reduces the risk of water sloshing, overflow, or tipping during the movement of the aquarium, improving the stability and safety of the water-carrying movement process.

[0054] In some embodiments, the preset acceleration limit rule can be determined based on at least one of the following: the current water level of the aquarium body, the size of the aquarium body, the wheel track of the movable base, the height of the obstacle, the slope, the path curvature, and the amplitude of water surface sloshing. When the current water level is higher, the path slope is greater, the obstacle height is higher, or the path curvature is greater, the control module can set lower speed and acceleration limits to reduce the amplitude of water sloshing.

[0055] In some embodiments, the control module can determine the light intensity and duration of illumination at the current location of the aquarium based on external light data. When the control module detects that the light intensity at the current location is lower than the suitable light threshold for fish and the duration exceeds a preset time threshold, it can control the movable base to move the aquarium body to a supplementary lighting point or a viewing lighting point; when the control module detects that the light intensity at the current location is higher than the suitable light threshold for fish and the duration exceeds a preset time threshold, it can control the movable base to move the aquarium body to a shaded point or a charging base point.

[0056] The locations for supplemental lighting, shaded areas, and viewing lighting can be automatically determined by the system based on the indoor space map, window positions, and historical lighting data, or they can be manually marked by the user on the indoor space map. If the control module detects a large number of movable obstacles, such as people, pets, or other robots obstructing the aquarium's lighting or affecting movement safety, it can control the mobile base to avoid the obstacles. If the obstacles are too dense to move safely, it can control the mobile base to stop and send a waiting instruction message to the user terminal.

[0057] In some embodiments, the control module can identify the number of fish, their activity level, and their appearance based on images or videos captured by an internal fish tracking camera. Specifically, the control module can perform target detection or image recognition on the fish images to determine the fish's position, swimming trajectory, activity frequency, and appearance characteristics within the aquarium, and determine the fish's activity level based on the distance the fish travels, its swimming speed, or its stationary state within a preset time period. The control module can also compare the captured images of the fish's appearance with preset images of healthy or abnormal fish to identify whether the fish have any appearance abnormalities, such as abnormal body surface, abnormal scales, abnormal behavior, or other suspected disease characteristics.

[0058] Here, when the control module detects abnormalities in the fish's appearance or activity level, it can control the transparent display device to show digital alerts and send fish health tips and maintenance suggestions to the user terminal via the communication module. Maintenance suggestions may include isolation and observation, water changes, water temperature adjustment, increased oxygen supply, water quality checks, or reference to relevant fish disease prevention and control information.

[0059] In some embodiments, the ecological regulation module may include a heating unit, an oxygenation unit, a filtration unit, a lighting unit, and an ambient lighting unit. The heating unit may be located inside the aquarium body or connected to a water circulation pipeline for regulating the aquarium water temperature; the oxygenation unit provides oxygen to the water inside the aquarium body; the filtration unit may be located on the top or side of the aquarium body for circulating and filtering the aquarium water; and the lighting unit or ambient lighting unit may be located on the top or inside of the aquarium body for providing lighting or ambient lighting for the interior of the aquarium.

[0060] Specifically, the control module can determine whether the aquarium's ecological environment is abnormal based on water temperature, water quality, pH, dissolved oxygen, ammonia nitrogen levels, or fish activity. When an abnormality is detected, the control module can first output maintenance suggestions through a transparent display device and the user terminal, and wait for user feedback. If no user feedback is received within a preset waiting time, the control module will automatically control the corresponding ecological adjustment module to perform adjustment operations based on the type of abnormality. For example, when the water temperature is below the target temperature range, the control module controls the heating unit to work; when the dissolved oxygen level is below the target dissolved oxygen range, the control module controls the oxygenation unit to work; when the water quality or ammonia nitrogen level is abnormal, the control module controls the filtration unit to strengthen filtration; when the lighting conditions are abnormal, the control module controls the lighting unit or ambient lighting unit to adjust the lighting status.

[0061] In some embodiments, the control module can also record historical operating data of the aquarium. This historical operating data may include at least one of the following: water temperature change data, water quality change data, pH change data, dissolved oxygen change data, ammonia nitrogen change data, fish population change data, fish activity change data, light intensity change data, movement route data, and user control records. The control module can generate trend charts based on the historical operating data and display them via a transparent display device or user terminal. Users can understand the changing trends of the aquarium's ecological environment based on the trend charts, thereby adjusting feeding, water changes, lighting, or equipment operation strategies. The control module can also predict abnormal conditions based on historical operating data, such as proactively alerting users to perform water changes or filter maintenance based on trends of water quality deterioration.

[0062] In some embodiments, the communication module can connect to the user terminal via Wi-Fi, Bluetooth, or other wireless communication methods. The user terminal can have an application installed corresponding to the mobile digital human aquarium. Users can remotely view the aquarium's operating status, environmental data, fish status data, historical trend data, and device alarm information through the application, and can also control the mobile digital human aquarium through the application. For example, users can control the transparent display device to change the digital human's appearance or virtual scene, control the ecological regulation module to perform heating, oxygenation, filtration, or lighting adjustments, or control the mobile base to move to a designated location. The communication module can also establish a communication connection with a server to obtain fishkeeping knowledge, fish disease prevention and control knowledge, weather information, and local light duration information. The control module can combine the information returned by the server to generate interactive content for the digital human, fish care suggestions, or mobile control strategies.

[0063] In some embodiments, the transparent display device can be used to implement digital human interactive display. The digital human interactive display can include status reporting, anomaly alerts, fishkeeping knowledge explanations, maintenance process guidance, and virtual scene demonstrations. When a user is near the device, the control module can detect the user's interaction needs through a microphone array, camera, or other user sensing devices, and control the transparent display device to display a digital human image to interact with the user. For example, the digital human can report the current water temperature, water quality, fish activity level, fish quantity, or device operating status to the user; when an anomaly is detected in the aquarium, the digital human can prompt the user to perform maintenance operations via voice or text. The transparent display device can also display underwater corals, natural aquatic plants, or other virtual backgrounds according to the user's selection, allowing the virtual scene to be overlaid with the real fish and landscape inside the aquarium, thereby enriching the viewing experience of the aquarium.

[0064] See Figure 3 As shown, Figure 3 This is a schematic diagram of the interactive logic flow of a mobile digital human ecological fish tank provided in an embodiment of this disclosure.

[0065] S101. Obtain spatial perception data of the indoor space where the mobile digital human ecological fish tank is located, and construct an indoor space map based on the spatial perception data. The indoor space map includes at least one of a movable area, a restricted access area, a target dwelling area, a charging base area, and a viewing and lighting area.

[0066] S102. Obtain environmental status data of the main body of the fish tank, wherein the environmental status data includes at least one of water status data, fish status data, light status data, and movement path status data.

[0067] S103. Determine the aquarium's operating status based on the environmental status data. The aquarium's operating status includes at least one of the following: aquatic ecological status, fish health status, current location lighting status, and movement safety status.

[0068] S104. Generate a corresponding execution strategy based on the fish tank's operating status. The execution strategy includes at least one of the following: digital human interaction display strategy, virtual scene display strategy, ecological regulation strategy, motion control strategy, and user prompt strategy.

[0069] S105. Based on the execution strategy, control the transparent display device to display digital human interactive content and / or virtual scenes, control the ecological regulation module to regulate the ecological environment inside the fish tank body, and / or control the mobile base to move the fish tank body to the target position.

[0070] In practical implementation, the mobile digital human ecological fish tank can be equipped with a mobile digital human interaction system. This system can run within the control module, or it can operate collaboratively with a server or user terminal. The mobile digital human interaction system comprehensively processes the indoor spatial environment, the fish tank's ecological environment, the fish's condition, and user interaction needs. Based on the processing results, it controls the mobile base, transparent display device, ecological regulation module, and communication module to perform corresponding actions.

[0071] Specifically, when the mobile digital human-themed aquarium enters a new indoor scene for the first time, or when a user triggers a new scene import operation, the control module can control the mobile base to move the aquarium body around the indoor space, collecting indoor space data through external cameras, base sensors, and light sensors. This indoor space data can include wall locations, furniture locations, door and window locations, ground obstacle locations, slope sections, charging base locations, and indoor lighting distribution information. Based on the collected indoor space data, the control module constructs an indoor space map and marks accessible areas, restricted access areas, areas where the target is usually located, viewing and lighting areas, and charging base areas on the map.

[0072] Here, users can also manually adjust the indoor space map via the user terminal or transparent display device, such as marking the desired permanent location of the fish tank, the location where the fish tank should be kept out of reach, or suitable viewing spots. The control module updates the indoor space map based on the user's markings to ensure that subsequent movement control better meets the user's needs.

[0073] Furthermore, when constructing the indoor space map, the control module can combine the positions of doors and windows, the light intensity collected by the light sensor module, and the location and weather information obtained from the server to determine the lighting conditions at different points in the indoor space. Based on the suitable lighting conditions for different fish species, the control module can determine supplementary lighting points, shaded areas, and viewing lighting points on the indoor space map. Therefore, when the current location of the aquarium is under-lit or over-lit, the mobile digital human-shaped ecological aquarium can proactively move to a suitable location according to the fish's needs, rather than passively accepting changes in lighting at a fixed position.

[0074] In some embodiments, when controlling the movement of the mobile base, the control module can plan a movement route from the current location to the target location based on an indoor space map. During the movement, the control module continuously collects movement path status data through an external camera and base sensors, and identifies ground obstacles, slope sections, moving obstacles, and passage widths in the path.

[0075] Here, when there are obstacles or sloping sections in the movement route, the control module can determine the chassis attitude angle and liquid surface sway amplitude when the aquarium body passes through the obstacle or sloping section based on the height, width, and slope of the obstacle, the wheel track of the moving base, and the current water level of the aquarium body. If the current water level is high or the liquid surface sway amplitude may exceed a preset threshold, the control module can limit the moving speed of the moving base and prompt the user to lower the water level through a transparent display device or user terminal. If the actual liquid surface sway amplitude exceeds the preset sway threshold during movement, the control module can control the moving base to stop moving forward or backward, replan the movement route, and output a movement anomaly prompt to the user. This improves the safety of moving the aquarium with water.

[0076] In some embodiments, the control module can collect the light intensity and duration of light at the current location through the light sensing module at the top of the aquarium and the light sensing recognition module at the bottom, and compare the light intensity and duration of light with the suitable light conditions for the current fish.

[0077] Specifically, when the light intensity at the current location is below the suitable light threshold for fish and the duration exceeds a preset time threshold, the control module can determine supplementary lighting points or viewing lighting points based on the indoor space map, and control the movable base to move the aquarium body to those points. When the light intensity at the current location is above the suitable light threshold for fish and the duration exceeds a preset time threshold, the control module can determine shaded areas or charging base areas based on the indoor space map, and control the movable base to move the aquarium body to those points.

[0078] It should be noted that if the control module detects that movable obstacles such as crowds, pets, or other robots are blocking the light or affecting the safety of movement, it can control the mobile base to perform obstacle avoidance actions; if the density of obstacles exceeds a preset density threshold, it will control the mobile base to stop and send a waiting instruction message to the user terminal.

[0079] In some embodiments, the control module can periodically acquire fish images or videos through an internal fish tracking camera, and determine the number of fish, their activity level, and their appearance based on these images or videos. Specifically, the control module can perform target recognition on the fish images to obtain the location and number of fish targets; track fish targets in consecutive image frames to obtain fish movement trajectories; and determine the swimming distance, swimming speed, dwell time, and activity frequency of the fish within a preset time period based on the fish movement trajectories, thereby determining the fish activity level. The control module can also extract fish appearance features and compare these features with preset healthy fish features or abnormal fish features to identify whether the fish have any appearance abnormalities. For example, when abnormalities in scales, body surface, posture, or activity are detected in the fish, the control module can determine that the fish's health status is abnormal.

[0080] In some embodiments, when the control module determines that the fish's health status is abnormal, it can generate fish health alert information and corresponding maintenance suggestions, control the transparent display device to display the digital human reminder content, and simultaneously push the abnormality alert to the user terminal through the communication module. Maintenance suggestions can be determined based on the type of abnormality, and may include adjusting water temperature, increasing oxygen supply, checking water quality, changing water, isolating and observing fish, reducing feeding, or referring to relevant fish disease prevention and control knowledge.

[0081] Furthermore, the control module can connect to the server via the communication module to obtain fish farming knowledge or disease prevention and control knowledge corresponding to the current fish species, abnormal appearance characteristics, and water condition data, and transform the acquired knowledge into digital human interactive content, which is then displayed to the user through a transparent display device.

[0082] In some embodiments, the control module can continuously or periodically collect water state data such as water temperature, water quality, pH, dissolved oxygen, and ammonia nitrogen levels within the aquarium via a water sensing unit, and compare this data with the suitable water parameter ranges for the corresponding fish species. When at least one of the following conditions—water temperature, water quality, pH, dissolved oxygen, ammonia nitrogen, and fish activity—is abnormal, the control module can first output maintenance suggestions through a transparent display device and the user terminal, and then wait for user feedback. If user feedback is received within a preset waiting time, the control module can execute the corresponding operation based on the user feedback; if no user feedback is received within the preset waiting time, the control module can automatically control the ecological regulation module to perform corresponding actions based on the type of abnormality.

[0083] For example, the system can control the heating unit when the water temperature is below the target range; control the oxygen generation unit when the dissolved oxygen level is below the target range; control the filtration unit when the water quality or ammonia nitrogen level is abnormal; and control the lighting unit or ambient lighting unit to adjust the lighting status when the lighting conditions are unsuitable. Therefore, even when the user cannot handle abnormal situations in a timely manner, the system can still perform basic maintenance on the aquarium's ecosystem.

[0084] In some embodiments, the transparent display device can be used to display a digital human figure, aquarium status information, a virtual scene, and an interactive interface. Users can select the digital human figure, interactive flow, or virtual scene through a user terminal, voice commands, touch operation, or other interactive methods. The control module controls the transparent display device to display the corresponding digital human figure or virtual scene based on the user's selection, allowing the virtual scene to be overlaid with the real fish and real landscape within the aquarium.

[0085] For example, transparent displays can show backgrounds of underwater corals, aquatic plants, holiday themes, or other decorative elements, thus altering the visual effect of the aquarium without changing the actual aquascape inside. Digital avatars can be used to report current water temperature, water quality, fish numbers, fish activity levels, equipment status, and maintenance recommendations to users. They can also be used to explain fishkeeping knowledge or guide users through maintenance procedures.

[0086] In some embodiments, when the user is near the mobile digital human aquarium, the control module can identify the user's interaction needs through a microphone array, camera, or other user sensing devices, and control the transparent display device to perform local digital human interaction. When the user is far from the device, the control module can establish a communication connection with the user terminal through the communication module, enabling the user to remotely view the aquarium status and control the aquarium equipment through the user terminal. The user terminal can display water temperature, water quality, pH, dissolved oxygen, ammonia nitrogen, number of fish, fish activity, historical trend charts, and abnormal prompts. The user can also send control commands through the user terminal to control the transparent display device to change the digital human image or virtual scene, control the ecological regulation module to perform heating, oxygenation, filtration, or lighting adjustment, or control the mobile base to move to a designated location.

[0087] In some embodiments, the mobile digital human-themed aquarium can also be linked with other smart home devices. For example, when a smart door lock, door magnetic sensor, or home control device detects that a user has returned home, it can send a home arrival notification to the control module. After receiving the home arrival notification, the control module can control the transparent display device to display a digital human greeting and simultaneously display or broadcast a fish tank status report. The fish tank status report may include at least one of the following: daily water status, fish status, equipment operating status, anomaly handling records, and maintenance suggestions. Thus, the mobile digital human-themed aquarium can not only be used as a fish tank but also as a smart home interaction terminal to provide users with anthropomorphic information services.

[0088] In some embodiments, the control module can record historical operating data of the aquarium, which may include at least one of the following: water condition data, fish condition data, lighting condition data, movement route data, ecological regulation records, user control records, anomaly alert records, and maintenance and handling records. The control module can generate aquarium ecological environment change trends based on the historical operating data and display them in chart form via a transparent display device or user terminal. Users can understand water quality changes, water temperature changes, fish activity changes, and equipment operation status based on these trends, thereby adjusting feeding, water changes, lighting, filtration, or movement strategies. The control module can also determine whether there is a continuous deterioration trend in the aquarium's ecological environment based on historical operating data and issue early warnings to the user before any anomalies occur.

[0089] This disclosure provides a mobile digital human-themed ecological fish tank. By integrating a mobile base, a transparent display device, a digital human interaction system, an environmental sensing module, an ecological adjustment module, and a communication module onto the main body of the fish tank, the fish tank can intelligently monitor, interactively display, ecologically adjust, and relocate based on water conditions, fish conditions, lighting conditions, and indoor space environment. This improves the ease of use of the fish tank, enriches the viewing experience, helps users understand the status of fish and water in a timely manner, and provides maintenance suggestions or performs corresponding adjustment operations in abnormal situations, thereby enhancing the ecological maintenance effect, interactive experience, and level of intelligence of the fish tank.
