[0046] The gate of the MOS tube Q3 is electrically connected with one end of the resistor R11 and one end of the resistor R10 respectively, the other end of the resistor R11 is electrically connected with the wireless Bluetooth WiFi dual-mode module, the source of the MOS tube Q3 is electrically connected with the other end of the resistor R10, one end of the resistor R6 and one end of the resistor R4 respectively, the other end of the resistor R4 is grounded, the other end of the resistor R6 is electrically connected with one end of the resistor R5, the other end of the resistor R5 is electrically connected with the wireless Bluetooth WiFi dual-mode module, the drain of the MOS tube Q3 is electrically connected with one end of the inductor L2 and the anode of the diode D1 respectively, the other end of the inductor L2 is electrically connected with one end of the capacitor C6, the anode of the diode D2 and the fourth pin of the connector J1 respectively, the cathode of the diode D1 is electrically connected with the other end of the capacitor C6, the cathode of the diode D2 and the third pin of the connector J1 respectively and the cathode of the diode D1, the other end of the capacitor C6, the cathode of the diode D2 and the third pin of the connector J1 are all connected with a 12V power supply, the opposite ends of the thermistor NTC are electrically connected with the first pin of the connector J1 and the second pin of the connector J1 respectively, the third pin of the connector J1 and the fourth pin of the connector J1 are electrically connected with two ends of the water pump respectively.

[0047] As can be seen from the above description, the resistor R4 is a sampling resistor, when the MOS tube Q3 is turned on, the current flowing through the water pump motor will flow through the MOS tube Q3 and the resistor R4 to GND; when the water pump motor stalls, the current will increase, and the voltage drop on the resistor R4 will also increase; the wireless Bluetooth WiFi dual-mode module can determine whether the water pump motor stalls by reading the voltage value on the resistor R4 through the ADC;

[0060] Please refer to Figure 4 , the infrared surplus detection module 2 further comprises resistors R13 and R14, one end of the resistor R13 is electrically connected with one end of the resistor R14 and the base of the transistor Q1 respectively, the other end of the resistor R13 is electrically connected with the eleventh pin of the chip U1, and the other end of the resistor R14 is grounded.

[0065] The detection principle of whether the feeder is installed or not depends on the infrared emitting tube and the infrared receiving tube in the feeder, and the specific analysis is as follows:

[0066] When the feeder is not installed, IRLED+ is connected to the 3.3V power supply through the resistor R55 (120 ohms), so it is 3.3 high level, so that the transistor Q2 is turned on, and the collector output of the transistor Q2 is always low level.

[0067] When the feeder is installed, IRLED+ and IRLED- are connected with the infrared emitting tube, and the system will turn on the infrared emitting tube for 100ms every 5 seconds through IR_SEND. During the conduction period, IRLED- is close to 0V, and the voltage across the infrared emitting tube is 1.2-1.3V, so the potential of IRLED+ is 1.2-1.3V. After the voltage is divided by the resistors of 100k and 47k, it is not enough to turn on the transistor Q2, so the collector of the transistor Q2 becomes high level. That is to say, when the feeder is installed, the WSQ_DET port will receive a 100ms high pulse every 5 seconds.

[0068] WSQ_DET determines whether the feeder is installed or not by whether it receives a 100ms high pulse.

[0069] The aquarium further comprises a water pump 5 and a locked-rotor detection module 4, and the locked-rotor detection module 4 is electrically connected with the wireless Bluetooth WiFi dual-mode module 1 and the water pump 5 respectively.

[0071] The gate of the MOS tube Q3 is electrically connected with one end of the resistor R11 and one end of the resistor R10, the other end of the resistor R11 is electrically connected with the wireless Bluetooth WiFi dual-mode module 1, the source of the MOS tube Q3 is electrically connected with the other end of the resistor R10, one end of the resistor R6 and one end of the resistor R4, the other end of the resistor R4 is grounded, the other end of the resistor R6 is electrically connected with one end of the resistor R5, the other end of the resistor R5 is electrically connected with the wireless Bluetooth WiFi dual-mode module 1, the drain of the MOS tube Q3 is electrically connected with one end of the inductor L2 and the anode of the diode D1, the other end of the inductor L2 is electrically connected with one end of the capacitor C6, the anode of the diode D2 and the fourth pin of the connector J1, the cathode of the diode D1 is electrically connected with the other end of the capacitor C6, the cathode of the diode D2 and the third pin of the connector J1, and the cathode of the diode D1, the other end of the capacitor C6, the cathode of the diode D2 and the third pin of the connector J1 are all connected with a 12V power supply, the opposite ends of the thermistor NTC are electrically connected with the first pin of the connector J1 and the second pin of the connector J1 respectively, and the third pin of the connector J1 and the fourth pin of the connector J1 are respectively and correspondingly electrically connected with two ends of the water pump 5.

[0072] The resistor R4 is a sampling resistor, when the MOS tube Q3 is turned on, the current flowing through the water pump motor will flow through the MOS tube Q3 and the resistor R4 to the GND, when the water pump motor is blocked, the current will become larger, and the voltage drop on the resistor R4 will become larger, the chip U1 can judge whether the water pump motor is blocked by reading the voltage value on the resistor R4 through the ADC;

[0073] The resistor R6 and the capacitor C5, and the resistor R5 and the capacitor C2 form two-stage RC filtering, so that the voltage drop of the resistor R4 is more stable and accurate;

[0074] The resistor R11 is a current limiting resistor of the gate of the MOS tube Q3;

[0075] The resistor R10 is connected between the gate and the source of the MOS tube Q3, and functions to ensure that it is in an off state when there is no control signal, that is, to avoid causing false operation.

[0077] The gear of water pump 5 (a small motor 3 in essence) is controlled by PWM pulse signal, and the duty cycle of PWM is changed to change the voltage value supplied to water pump 5;

[0078] The power supply of water pump 5 shown in the figure has two loops, when PWM is high level, MOS tube Q3 is turned on, loop one is taken; when PWM is low level, MOS tube Q3 is not turned on, loop two is taken;

[0079] D1 is a freewheeling diode, because the voltage across the capacitor cannot change abruptly, the current in the inductor cannot change abruptly, so the capacitor C6 and the inductor L2 in the figure are just using the characteristics of capacitor and inductor, so that the water pump 5 can rotate more smoothly when the two loops are switched.

[0080] In loop one in the figure, the current flows through sampling resistor R4 (1 ohm 1% precision), and there is a voltage U across resistor R4, because one end is grounded at 0V, the potential at the other end is U, U is sent to the ADC port of chip U1 after two-pole RC filtering;

[0081] When working normally, the current is small, U is small, and chip U1 reads a small value;

[0082] When water pump 5 stalls, the current becomes large, U becomes large, and the value read by ADC becomes large; a suitable threshold value is set to determine whether water pump 5 stalls, if it stalls, the system stops water pump 5 from continuing to rotate, and reports to the APP end, so that the user knows to exclude the stall reason.

[0086] In order to generate alternating magnetic field, so the control signal needs to use PWM wave (BUZ_PWM4), instead of high level; Resistor R49 is a current limiting resistor, 1K can flow about 2.6mA current, through the transistor Q8 transistor amplification, drive the internal electromagnetic coil; When PWM is low, transistor Q8 is not conductive, diode D12 is to provide a discharge circuit for the electromagnetic coil, otherwise the coil will produce high voltage between the two ends;

[0087] Capacitor C26 is a power filter; Resistor R48 can speed up the discharge speed of the base of transistor Q8, so that the PWM waveform is better.

[0088] The aquarium is also provided with a lamp panel interface module 7, which is electrically connected with the wireless Bluetooth WiFi dual-mode module 1.
