[0035] Specifically, the working principle and operation process of the system are as follows:

[0036] The gas flow rate detection valve working in cooperation with the magnetic sensor 3 is connected to the gas pipeline. When the gas flows through the gas flow rate detection valve, it drives the wheel inside the gas flow rate detection valve to rotate. The rotation speed of the wheel is the flow rate of the gas. The wheel is provided with a synchronously rotating magnet. When the magnet rotates, it triggers the magnetic sensor 3. Therefore, the magnetic sensor 3 combined with the gas flow rate detection valve can detect the gas flow rate and transmit the information to the main control circuit 1. The main control chip U1 can calculate the gas volume within a period of time according to the diameter data of the gas pipeline. At this time, the main control circuit 1 can adjust the speed of the main fan through the main fan control circuit 4 in combination with the set optimal air-fuel ratio to achieve matching adjustment of the air-fuel ratio and make the gas burn fully.

[0037] The current transformer connected to the power detection circuit 7 is set on the live wire or neutral wire of the AC220V input power supply. The current transformer can measure the magnitude of the current flowing through according to the principle of electromagnetic induction. The power detection circuit 7 receives and processes the current information measured by the current transformer and transmits it to the auxiliary control circuit 2. Since the mains voltage is constant, the auxiliary control chip U6 can calculate the power loss within a period of time according to the magnitude of the current;

[0038] The water flow meter consists of a sensor and a converter. It works based on Faraday's law of electromagnetic induction and is used to measure the volume flow of conductive liquids with a conductivity greater than 5μS / cm. It can fully measure the flow information of the tap water pipe over a period of time. The water volume information can be transmitted to the auxiliary control circuit 2 through the third information transmission circuit 8.

[0039] The main control circuit 1 and the auxiliary control circuit 2 interactively transmit information on gas consumption, electricity consumption and water consumption through the first information transmission circuit 5 and the second information transmission circuit 6, and then send the information to the user's mobile phone terminal through the wireless transmission circuit 9, or transmit it to the display screen for display, so that the user can accurately and completely grasp the gas consumption, water consumption and electricity consumption of the stove over a period of time.

[0040] Specifically, the main control circuit 1 and the auxiliary control circuit 2 include a main control chip U1 and an auxiliary control chip U6, respectively. The dual control chip structure formed by the main control chip U1 and the auxiliary control chip U6 can process various sensor information in parallel, thereby effectively improving the operating efficiency of the system and enhancing the feedback adjustment speed of the system. The main control chip U1 and the auxiliary control chip U6 are respectively provided with a program burning port JP5 and a program burning port J12. The main control circuit 1 and the auxiliary control circuit 2 are respectively electrically connected to a first information transmission circuit 5 and a second information transmission circuit 6 for interactively transmitting information.

[0041] The system also includes a voltage conversion circuit 10 for powering the auxiliary control module, the voltage conversion circuit 10 is electrically connected to a step-down circuit 13 for powering the main control module, and the step-down circuit 13 is electrically connected to the voltage conversion circuit 10 through the port JP1 of the first information transmission circuit 5 and the port J8 of the second information transmission circuit 6; the voltage conversion circuit 10 includes a first power supply circuit 11 for converting the DC24V power output by the power adapter into a DC5V power supply, and a second power supply circuit 12 for converting the DC24V power output by the power adapter into a DC3.3V power supply. In addition to powering the system, the voltage conversion circuit 10 also powers each functional sensor module through the corresponding connection port, and the step-down circuit 13 converts the transmitted DC5V voltage into a DC3.3V voltage for powering the chip in the main control module.

[0042] Specifically, the main control circuit 1 is electrically connected to a clock circuit 14 for associating with real time, and a data storage circuit 15 for storing data information of gas, water and electricity consumed by the stove within a set time period. The clock circuit 14 and the data storage circuit 15 can be associated with real time and expand the data space of the system, so that users can accurately and completely grasp the data information of each day, each month or even each year, so as to facilitate users to control the stove and kitchen and prevent waste of resources.

[0043] In addition, the main control circuit 1 is electrically connected to an indicator light circuit 16 for displaying the operating status of the feedback system.

[0044] Specifically, the auxiliary control circuit 2 is electrically connected to a spark fan control port 17 for outputting a spark fan operation control signal, the spark fan control port 17 is electrically connected to the spark fan and is electrically connected to a spark fan power supply circuit 18 for supplying power to the spark fan alone. The gas volume in the spark gas pipeline is fixed and does not need to be adjusted. Therefore, the speed of the spark fan can be directly set according to the optimal air-fuel ratio.

[0045] Specifically, the auxiliary control circuit 2 is electrically connected to a sensor module interface 19 for accessing a gas concentration detection module to determine whether the gas is leaking. In addition, the auxiliary control circuit 2 is electrically connected to a fourth information transmission circuit 20 for accessing a flameout protector to control the solenoid valve on the gas pipeline to disconnect the gas delivery under abnormal circumstances; when an abnormal situation such as the fire is extinguished or the stove is extinguished, the flame detection sensor in the flameout protector detects the abnormal situation. At this time, the flameout protector will be triggered, thereby controlling the solenoid valve on the gas pipeline to work to disconnect the gas delivery. At the same time, the flameout protector will be triggered. The signal is transmitted to the auxiliary control circuit 2 through the fourth information transmission circuit 20, and the auxiliary control circuit 2 transmits a signal to the main control circuit 1 to control the system to stop running, so that the main fan and the fire fan stop working; when the gas concentration detection module connected to the sensor module interface 19 detects a gas leak, the auxiliary control circuit 2 transmits a control signal to the flameout protector through the fourth information transmission circuit 20 to trigger the above-mentioned flameout protection program; after the flameout protector is triggered, the fuel valve on the stove needs to be reset to zero. After the abnormal situation is eliminated, the system can be restarted to resume use.

[0046] In addition, the auxiliary control circuit 2 is electrically connected to a fifth information transmission circuit 21 for connecting to a display screen. Since the display screen consumes a large amount of power, in order not to affect the power supply of other modules of the system, a display screen power supply circuit 22 that separately supplies power to the display screen can be set in the system and transmitted to the display screen through the port of the fifth information transmission circuit 21.

[0047] Specifically, the wireless transmission circuit 9 is a WiFi module, and the circuit structures of the first information transmission circuit 5, the second information transmission circuit 6, the third information transmission circuit 8, the fourth information transmission circuit 20 and the fifth information transmission circuit 21 are the same.
