In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, a fish tank control system based on a single-chip microcomputer includes a control module, which is electrically connected to a display module, a heating module, an oxygenation module, a water exchange module, a lighting module and a feeding module respectively. The control module, display module, heating module, oxygenation module, water exchange module, lighting module and feeding module are also electrically connected to a power supply module respectively.

[0022] Combine Figure 3 Specifically, the control module includes a single-chip microcomputer 2 (the model of single-chip microcomputer 2 is STC59C52), a crystal oscillator, a voltage stabilizing circuit, GPIO pins, a connector, and a reset circuit. The display module includes a display 3 (the model of display 3 is LCD1602). Display 3 is connected to single-chip microcomputer 2 via a parallel interface. The data line and control line of display 3 are connected to single-chip microcomputer 2 via appropriate pins. When the system is running, display 3 can display important parameters such as the current water temperature, light intensity, and water level status. At the same time, display 3 will also display the execution status of tasks such as timed oxygen flushing, timed feeding, and timed water changes. Display 3 also provides a simple operation interface. Users can use buttons on display 3 to perform some basic setting operations, such as setting timing parameters, switching to manual control mode, etc. In this way, users can intuitively understand the system status and parameters and conveniently perform operations and settings.

[0023] The heating module includes a first relay 4, a heater and a temperature sensor 8 (the model of the temperature sensor 8 is DS18B20). The temperature sensor 8 is electrically connected to the single-chip microcomputer 2. The single-chip microcomputer 2 is electrically connected to the first relay 4 and the heater. The temperature sensor 8 detects the water temperature in the fish tank and transmits the signal directly to the single-chip microcomputer 2. The single-chip microcomputer 2 turns on or off the heater by controlling the first relay 4. When the water temperature is lower than the set temperature threshold, the first relay 4 will be triggered and the heater will be powered on. Once the temperature reaches the set value, the first relay 4 will be disconnected and heating will stop. This can ensure that the fish in the fish tank are always at a suitable temperature and ensure the survival of the fish.

[0024] The oxygenation module includes a second relay 5 and an oxygen pump. The single chip microcomputer 2 is electrically connected to the second relay 5 and the oxygen pump. The single chip microcomputer 2 controls the second relay 5 to turn on or off the oxygen pump to ensure that the fish is always in an environment with suitable oxygen content and ensure the survival of the fish.

[0025] Combine Figure 4 Specifically, the water change module includes a drain pump, a third relay 6, a water suction pump, a fourth relay 7, a low water level sensor 9 and a high water level sensor 10. The low water level sensor 9 and the high water level sensor 10 are respectively installed at the bottom and the top of the inner wall of the fish tank. The low water level sensor 9 and the high water level sensor 10 are electrically connected to the single-chip microcomputer 2. The single-chip microcomputer 2 is electrically connected to the third relay 6 and the drain pump. The single-chip microcomputer 2 is also electrically connected to the fourth relay 7 and the water suction pump. The low water level sensor 9 and the high water level sensor 10 send a signal to the single-chip microcomputer 2. After receiving the signal, the single-chip microcomputer 2 controls the third relay 6 to open or close the drain pump. After receiving the signal, the single-chip microcomputer 2 can also control the fourth relay 7 to open or close the water suction pump.

[0026] The lighting module includes a photoresistor 11 (the photoresistor 11 is an existing product, its model is GL5506), an analog-to-digital conversion chip 12 and a lighting lamp 13. The single-chip microcomputer 2 is electrically connected to the photoresistor 11 through the analog-to-digital conversion chip 12 (the model of the analog-to-digital conversion chip 12 is ADC0832), and the photoresistor 11 is electrically connected to the lighting lamp 13. The analog output signal of the photoresistor 11 is connected to the analog input port of the single-chip microcomputer 2 through the analog input pin of the analog-to-digital conversion chip 12. In order to ensure the stability and anti-interference ability of the signal, a suitable filtering circuit is added between the photoresistor 11 and the analog-to-digital conversion chip 12 to reduce noise interference. The single-chip microcomputer 2 controls the lighting lamp 13, so that when the light is dim, the lighting lamp 13 illuminates the fish tank.

[0027] The feeding module includes a drive motor 14 (the drive motor 14 is a 5-wire 4-phase stepper motor of model 28BYJ-48), a motor chip 15 (the model of the motor chip 15 is ULN2003) and a feeding device. The IO port of the single-chip microcomputer 2 is connected to the input pin of the motor chip 15 to send a pulse signal to the drive motor 14. The output end of the drive motor 14 is connected to the feeding device. The single-chip microcomputer 2 controls the drive motor 14 through the motor chip 15, so that the fish tank can be fed regularly.

[0028] Combine Figure 5 Specifically, the first relay 4, the second relay 5, the third relay 6 and the fourth relay 7 are all parts of the same model.
