Description

Technical Field

[0001] This invention relates to the technical field of intelligent aquarium control, specifically to a semiconductor bidirectional temperature-controlled aquarium control circuit and method with integrated voice control. Background Technology

[0002] Currently, commercially available aquarium control devices generally suffer from the following technical defects:

[0003] The temperature control function is limited and lacks precision. Existing solutions mostly use independent heating rods or compressor cooling modules, which can only achieve unidirectional heating or unidirectional cooling, and cannot achieve bidirectional temperature regulation on a single actuator. Even some high-end products are equipped with both heating and cooling systems, but their control logic is independent on / off control, lacking the closed-loop continuous adjustment capability based on PID algorithms. This results in large water temperature fluctuations, making it difficult to meet the survival needs of aquarium organisms such as ornamental fish, aquatic plants, and corals that require a constant temperature environment.

[0004] The functional modules are highly discrete, resulting in low system integration. The cooling module, heating module, circulating water pump driver, lighting driver, and emerging voice interaction components all exist as independent controllers, lacking a unified information exchange and control scheduling mechanism between the modules. This discrete architecture directly leads to complex wiring during installation, bulky size, numerous power adapters, high overall hardware costs, and difficulties in troubleshooting, severely impacting the product's applicability and user experience in desktop and miniaturized application scenarios.

[0005] Intelligent interaction methods are lagging behind. The vast majority of products still rely on physical buttons, knobs, or infrared remote controls for parameter setting, lacking localized voice recognition and linkage control functions. The few solutions that support remote control via mobile APP generally suffer from problems such as cumbersome network configuration processes, high control latency, and limited functionality when offline, failing to provide a natural and convenient contactless intelligent management experience.

[0006] There is a market gap in ultra-miniaturization and desktop ecosystem integration. Currently, there is no mature, integrated control system for miniature aquariums designed for compact spaces such as office desks and bedside tables. This system unifies the functions of semiconductor bidirectional temperature control, multi-stage filtration, intelligent lighting, voice interaction, automatic feeding, and air purification through a single main control logic. Existing technologies are either incomplete or bulky, failing to meet consumers' urgent demand for highly integrated and intelligent desktop aquarium products.

[0007] Based on this, the present invention provides a control circuit and method for an integrated voice-controlled semiconductor bidirectional temperature-controlled aquarium. Summary of the Invention

[0008] To address the problems mentioned in the background art, this invention provides an integrated voice-controlled semiconductor bidirectional temperature-controlled aquarium control circuit and method. Regardless of whether the functional circuits are physically integrated on the same PCB, as long as the single master control scheduling logic of this invention is followed, ultra-miniaturization and optimization of hardware costs can be achieved, effectively solving the pain points of traditional aquarium equipment stacking, messy wiring, and difficult maintenance.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] The integrated voice-controlled semiconductor bidirectional temperature-controlled aquarium control circuit includes:

[0011] Main control unit, power management unit, temperature acquisition unit, semiconductor cooling and heating drive unit, water pump drive unit, lighting drive unit and sound control unit;

[0012] The main control unit is electrically connected to the temperature acquisition unit, the semiconductor cooling and heating drive unit, the water pump drive unit, the light drive unit, and the sound control unit, respectively.

[0013] The main control unit is used to uniformly schedule and control various functional units to achieve cooling, heating, closed-loop constant temperature maintenance, water pump operation adjustment, lighting adjustment, and intelligent control based on voice commands for aquarium water.

[0014] Furthermore, the semiconductor cooling and heating drive unit adopts an H-bridge bidirectional drive circuit structure to drive the semiconductor cooling chip to switch between cooling mode and heating mode.

[0015] Furthermore, the main control unit is equipped with a PID control algorithm module, which is used to adjust the semiconductor cooling and heating drive unit according to the comparison result of the water temperature fed back by the temperature acquisition unit in real time and the set target temperature to achieve precise constant temperature control.

[0016] Furthermore, the voice control unit is used to receive and recognize external voice commands and transmit the recognition results to the main control unit. The main control unit performs control operations on water temperature setting, cooling / heating mode switching, water pump operation status and light status according to the recognition results.

[0017] Furthermore, the temperature acquisition unit includes a digital temperature sensor or an analog thermistor.

[0018] Furthermore, the water pump drive unit includes a MOS transistor drive circuit, and the water pump drive unit supports speed control of the water pump through a pulse width modulation signal.

[0019] Furthermore, the lighting drive unit supports pulse width modulation dimming control, which is used to realize the brightness adjustment and on / off control of the lamp.

[0020] A method for integrating a sound-controlled semiconductor bidirectional temperature-controlled aquarium control circuit, applied to an integrated sound-controlled semiconductor bidirectional temperature-controlled aquarium control circuit, includes the following steps:

[0021] The system performs initialization operations after power-on;

[0022] The temperature acquisition unit collects the water temperature data in the aquarium in real time and transmits the water temperature data to the main control unit.

[0023] The main control unit compares the received water temperature data with the preset target temperature, and controls the semiconductor cooling and heating drive unit to perform cooling operation, heating operation, or maintain the current state to achieve constant temperature control based on the comparison result.

[0024] The voice control unit recognizes the user's voice commands and transmits the recognized command information to the main control unit. The main control unit executes the corresponding function operation according to the command information. The function operation includes at least one of the following: water pump operation adjustment, light status adjustment, and temperature control parameter adjustment.

[0025] The system monitors abnormal circuit conditions in real time during operation and executes preset protection actions when an abnormality is detected.

[0026] Compared with existing technologies, the integrated voice-controlled semiconductor bidirectional temperature-controlled aquarium control circuit and method provided by this invention breaks through the industry status quo that traditional solutions require independent controllers for each functional module (temperature control, filtration, lighting, voice, feeding, and purification). By constructing a star control topology centered on a single master controller, it deeply integrates six subsystems—semiconductor bidirectional temperature control drive, water pump speed regulation, lighting dimming, voice control interpretation, automatic feeding triggering, and air purification start / stop—under a single control logic. Regardless of whether the functional circuits are physically integrated on the same PCB, as long as the single master controller scheduling logic of this invention is followed, ultra-miniaturization and hardware cost optimization can be achieved, effectively solving the pain points of traditional aquarium equipment stacking, messy wiring, and difficult maintenance.

[0027] By utilizing an H-bridge bidirectional drive circuit to control the current flow of the same thermoelectric cooler (TEC), hardware reuse for both cooling and heating functions is achieved without adding a separate heating rod. Compared to the existing technology where the cooler can only cool and the heating rod can only heat, this invention not only simplifies the hardware structure and reduces material costs, but also dynamically adjusts the drive power through the PID algorithm module built into the main control unit. This allows for precise control of aquarium water temperature fluctuations within a very small threshold range (e.g., ±0.5℃), ensuring the stability of the aquarium's living environment and avoiding the temperature overshoot and energy waste caused by traditional relay-based temperature control.

[0028] By embedding the voice control unit as a standard functional module into the main control and scheduling system, users no longer need to operate physical buttons or mobile apps. They only need to issue natural voice commands (such as "feed," "purify," and "turn on the lights"), and the main control unit can automatically recognize and synchronously schedule the feeding motor, purifier generator, and lighting PWM signals. This integrated voice linkage mechanism simplifies aquarium management from tedious manual operations to a single sentence, greatly improving the product's intelligence level and user convenience, making it especially suitable for modern desktop applications that prioritize a high-tech feel.

[0035] The main control unit is electrically connected to the temperature acquisition unit, the semiconductor cooling and heating drive unit, the water pump drive unit, the lighting drive unit, and the sound control unit, respectively.

[0036] The main control unit is used to uniformly schedule and control various functional units to achieve aquarium water cooling, heating, closed-loop constant temperature maintenance, water pump operation adjustment, lighting adjustment, and intelligent control based on voice commands.

[0037] Specifically, the main control unit, serving as the control center and data processing core of the entire system, is implemented using a microcontroller (MCU) or a microprocessor (MPU). This main control unit internally contains complete control logic and PID algorithm modules.

[0038] Power Management Unit: Used to convert external input voltage to different voltage levels (such as 5V, 3.3V, 12V) required by various functional units, and provides overvoltage, overcurrent and surge protection;

[0045] Air purification execution interface: Reserved interface for negative ion generator or mini fan drive, for connecting air purification module.

[0046] This invention breaks through the industry standard where each functional module (temperature control, filtration, lighting, voice, feeding, and purification) requires an independent controller. By constructing a star control topology centered on a single master controller, it deeply integrates six subsystems—semiconductor bidirectional temperature control drive, water pump speed regulation, lighting dimming, voice control interpretation, automatic feeding triggering, and air purification start / stop—under a single control logic. Regardless of whether the functional circuits are physically integrated on the same PCB, as long as the single master controller scheduling logic of this invention is followed, ultra-miniaturization and optimized hardware costs can be achieved, effectively solving the pain points of traditional aquarium equipment stacking, messy wiring, and difficult maintenance.

[0047] Specifically, the semiconductor cooling and heating drive unit adopts an H-bridge bidirectional drive circuit structure to drive the semiconductor cooling chip to switch between cooling mode and heating mode.

[0048] By utilizing an H-bridge bidirectional drive circuit to control the current flow of the same thermoelectric cooler (TEC), hardware reuse for both cooling and heating functions is achieved without adding a separate heating rod. Compared to the existing technology where the TEC can only cool and the heating rod can only heat, this invention not only simplifies the hardware structure and reduces material costs, but also dynamically adjusts the drive power through the PID algorithm module built into the main control unit. This allows for precise control of aquarium water temperature fluctuations within a very small threshold range (e.g., ±0.5℃), ensuring the stability of the aquarium's living environment and avoiding the temperature overshoot and energy waste caused by traditional relay-based temperature control.

[0049] Specifically, the main control unit is equipped with a PID control algorithm module, which is used to adjust the semiconductor cooling and heating drive unit based on the comparison between the water temperature fed back by the temperature acquisition unit in real time and the set target temperature to achieve precise constant temperature control.

[0050] Specifically, the voice control unit is used to receive and recognize external voice commands and transmit the recognition results to the main control unit. The main control unit performs control operations on water temperature setting, cooling / heating mode switching, water pump operation status and light status according to the recognition results.

[0051] By embedding the voice control unit as a standard functional module into the main control and scheduling system, users no longer need to operate physical buttons or mobile apps. They only need to issue natural voice commands (such as "feed," "purify," and "turn on the lights"), and the main control unit can automatically recognize and synchronously schedule the feeding motor, purifier generator, and lighting PWM signals. This integrated voice linkage mechanism simplifies aquarium management from tedious manual operations to a single sentence, greatly improving the product's intelligence level and user convenience, making it especially suitable for modern desktop applications that prioritize a high-tech feel.

[0052] Specifically, the temperature acquisition unit includes a digital temperature sensor or an analog thermistor.

[0053] Specifically, the water pump drive unit includes a MOS transistor drive circuit, and the water pump drive unit supports speed control of the water pump through pulse width modulation signals.

[0054] Specifically, the lighting driver unit supports pulse width modulation dimming control, which is used to adjust the brightness of the lamps and control their on / off states.

[0055] Specifically, the main control unit is electrically connected to all units (temperature acquisition, semiconductor cooling and heating drive, water pump drive, lighting drive, voice control, automatic feeding interface, and air purification interface) to form a star control topology centered on a single main control unit. The main control unit performs unified timing scheduling and power allocation for each unit based on its internally fixed comprehensive decision-making algorithm, thereby achieving integrated intelligent control with multiple tasks running concurrently without interference.

[0056] The specific implementation of semiconductor bidirectional temperature control: The semiconductor cooling and heating drive unit integrates an H-bridge bidirectional drive circuit structure. The main control unit outputs a direction control signal and a PWM power signal based on the calculated temperature difference, controlling the conduction timing of the MOSFETs in the H-bridge. When current flows forward through the semiconductor cooling chip, cooling mode is achieved; when the main control unit controls the H-bridge to switch the current flow direction, the same semiconductor cooling chip switches to heating mode without adding an additional heating rod. Combined with the PID control algorithm module built into the main control unit, the system can control water temperature fluctuations within a very small threshold range (such as ±0.5℃), achieving truly precise bidirectional constant temperature.

[0057] The specific implementation of voice control and multi-device linkage control: The voice control unit has a built-in local offline voice recognition engine or recognizes commands through a cloud interface. When the user issues voice commands such as "turn on the lights", "set the water temperature to 26 degrees", "feed once", or "turn on the purifier", the voice control unit converts the recognition result into a digital command and transmits it to the main control unit. The main control unit coordinates the corresponding execution unit actions according to the command type. For example, after receiving the "feed" command, the main control unit will drive the stepper motor connected to the automatic feeding execution interface to rotate a specific angle to achieve quantitative feeding; after receiving the "purify" command, it will drive the air purification execution interface to start the negative ion generator to improve the desktop air environment.

[0058] The auxiliary functions are implemented as follows: the water pump drive unit uses MOS transistors to realize electronic switching and PWM speed regulation, so that the filtered water flow can be steplessly adjusted; the light drive unit also supports PWM dimming and can be used with the timer of the main control unit to realize the simulation of sunrise and sunset gradient; the temperature acquisition unit is compatible with digital (such as DS18B20) or analog (NTC thermistor) sensors, which facilitates the selection of materials for different cost options.

[0059] This invention uses a single master control logic as its core hub. Through the deep integration of current flow, data flow, and control flow, it provides an innovative aquarium control solution with ultra-small size, integrated cooling and heating energy saving, intelligent voice interaction, and full-ecosystem management. It has extremely high commercial promotion value and industry-leading significance.

[0062] After the system is powered on, it performs an initialization operation. Upon power-up, the main control unit first executes a self-test program, including reading preset factory parameters, checking the status of each sensor, and calibrating the clock reference. After initialization, the system defaults to intelligent temperature control and safety monitoring mode.

[0063] The temperature acquisition unit collects real-time water temperature data in the aquarium and transmits the water temperature data to the main control unit.

[0064] The main control unit compares the received water temperature data with the preset target temperature, and controls the semiconductor cooling and heating drive unit to perform cooling operation, heating operation, or maintain the current state to achieve constant temperature control based on the comparison result.

[0065] The voice control unit recognizes the user's voice commands and transmits the recognized command information to the main control unit. The main control unit executes the corresponding function operation according to the command information. The function operation includes at least one of the following: water pump operation adjustment, light status adjustment, and temperature control parameter adjustment.

[0066] The system monitors abnormal circuit conditions in real time during operation and executes preset protection actions when an abnormality is detected.

[0067] In summary, this invention deeply integrates six subsystems—semiconductor bidirectional precise temperature control, water circulation, multi-mode lighting, local voice interaction, automatic feeding, and air purification—through a unified scheduling approach using a single master control logic. This highly integrated control architecture not only achieves ultra-miniaturization of hardware but, more importantly, establishes a new standard for intelligent aquarium management, effectively addressing the industry pain points of traditional solutions such as equipment stacking, isolated control, and fragmented user experience.
