Description

Technical Field

[0001] This invention relates to the field of kitchen and bathroom appliance technology, specifically to a monitoring method and device for gas stoves, and a gas stove itself. Background Technology

[0002] For cooktops equipped with controllers, it's necessary to detect the pressed state of the ignition button. Related technologies use a connecting wire installed under the button to detect whether it's pressed, and the pressed state is determined by detecting whether the connecting wire is in contact. Specifically, if the ignition button is pressed, the connecting wire will make contact with the ignition button. Therefore, by checking if the connecting wire is conductive and generates a corresponding signal, it can be determined whether the ignition button is pressed. This detection method requires the connecting wire to be installed inside the cooktop, which is prone to inaccurate results due to loose connections. Summary of the Invention

[0003] In view of this, the present invention provides a gas stove monitoring method, device and gas stove to solve the problems of inaccurate detection results caused by the need to run connecting wires inside the stove for stove monitoring due to loose connections.

[0007] The gas stove monitoring method provided in this invention collects the battery voltage value of the gas stove and determines the status of the gas stove buttons based on changes in the battery voltage value. Since the voltage detection circuit is essential for gas stoves to detect remaining battery power, using this circuit in conjunction with the monitoring method of this invention effectively avoids the need for internal wiring to detect whether buttons are pressed, thus preventing inaccurate detection results due to loose connections. Furthermore, it reduces costs and effectively ensures the accuracy of gas stove button monitoring results.

[0013] The second moment is later than the first moment, and the interval between the second moment and the first moment is set to a period.

[0015] The gas stove monitoring method provided in this invention determines that the button is in a pressed state when the first difference between the first battery voltage value at a first moment and the second battery voltage value at a second moment is greater than a first threshold. This method fully utilizes the characteristic that the battery voltage value drops instantaneously and continuously when the button is pressed and the gas stove is ignited, thus quickly and accurately determining the button's pressed state.

[0017] Based on the battery voltage values ​​collected twice, determine whether the gas stove button is in the released state;

[0018] The two data collection times are the second time point and any time point after the second time point.

[0019] The gas stove monitoring method provided in this embodiment of the invention determines whether the gas stove button is in a released state based on two collected battery voltage values. It effectively judges the complete process of the button's state from being pressed to being released, which is beneficial for reasonable and effective monitoring of the gas stove.

[0020] In one optional implementation, determining whether the gas stove button is in a released state based on two collected battery voltage values ​​includes:

[0021] When the first difference between the third battery voltage value at the third moment and the second battery voltage value at the second moment is greater than the second threshold, the button is determined to be in the released state.

[0022] The third time point is later than the second time point;

[0023] The first threshold is greater than the second threshold.

[0024] In one alternative implementation, the method further includes:

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] This invention provides a method for monitoring a gas stove. It collects the battery voltage value of the gas stove and determines the status of the gas stove buttons based on changes in the battery voltage. Since the voltage detection circuit is essential for gas stoves to detect remaining battery power, using this circuit in conjunction with the monitoring method of this invention effectively avoids the need for internal wiring to detect button presses, thus preventing inaccurate results due to loose connections. Furthermore, it reduces costs and effectively ensures the accuracy of gas stove button monitoring results.

[0050] According to an embodiment of the present invention, a method for monitoring a gas stove is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0051] This embodiment provides a method for monitoring gas stoves, which can be used in gas stoves, etc. Figure 1 This is a flowchart of a gas stove monitoring method according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:

[0052] Step S101: Collect the battery voltage value of the gas stove at set intervals.

[0053] Specifically, the gas stove's battery powers its pulse igniter. When the gas stove is ignited, pressing the button sends an ignition pulse to the igniter. At this time, due to the large output current from the battery, the battery voltage drops noticeably for a short period. Releasing the button restores the battery voltage to its pre-ignition value.

[0054] Figure 2 This is a schematic diagram of the voltage detection circuit principle of the gas stove monitoring method according to an embodiment of the present invention, as shown below. Figure 2 As shown, based on the aforementioned battery voltage variation pattern of the gas stove, in this embodiment of the invention, a battery voltage detection point 203 can be set in the hardware circuit of the gas stove. A resistor R1 with a resistance of 330K is used to divide the voltage between the positive terminal 202 and the negative terminal of the battery. The battery voltage detection point 203 can be considered as a voltage divider point, which is connected to the analog-to-digital function port of the control chip 201 of the gas stove controller to collect the battery voltage data. A capacitor C1 with a capacitance of 0.1uF is also configured between the battery voltage detection point 203 and the ground terminal GND1. It should be noted that the resistance value of resistor R1 and the capacitance value of capacitor C1 can be set according to actual needs, and this invention does not limit them. Thus, by using the microcontroller peripheral function and AD conversion module (analog-to-digital conversion module) of the gas stove controller, the battery voltage value of the gas stove power supply battery can be periodically detected.

[0055] Step S102: Determine the status of the gas stove buttons based on the change in battery voltage.

[0056] Specifically, monitoring the ignition process of a gas stove can yield results such as... Figure 3 The diagram shows the changes in the battery voltage of the power supply battery, with the horizontal axis representing time and the vertical axis representing voltage. It can be observed that the battery voltage drops significantly when the button is pressed to ignite the gas stove. Within a certain time, it recovers to a fixed battery voltage value. Therefore, the state of the gas stove button can be determined based on the changes in the battery voltage.

[0057] The gas stove monitoring method provided in this invention collects the battery voltage value of the gas stove and determines the status of the gas stove buttons based on changes in the battery voltage value. Since the voltage detection circuit is essential for gas stoves to detect remaining battery power, using this circuit in conjunction with the monitoring method of this invention effectively avoids the need for internal wiring to detect whether buttons are pressed, thus preventing inaccurate detection results due to loose connections. Furthermore, it reduces costs and effectively ensures the accuracy of gas stove button monitoring results.

[0058] This embodiment provides a method for monitoring gas stoves, which can be used in gas stoves, etc. Figure 4 This is a flowchart of a gas stove monitoring method according to an embodiment of the present invention, such as... Figure 4 As shown, the process includes the following steps:

[0059] Step S401: Collect the battery voltage value of the gas stove at set intervals.

[0060] In one alternative implementation, the period is set to be less than or equal to 40 milliseconds.

[0061] For further details regarding step S401, please refer to [link / reference]. Figure 1 Step S101 of the illustrated embodiment will not be described again here.

[0062] Step S402: Determine the status of the gas stove buttons based on the change in battery voltage.

[0063] In an optional implementation, step S402 may include:

[0064] Step S4021: Based on the battery voltage values ​​collected in two consecutive steps, determine whether the button on the gas stove is in the pressed state.

[0065] Return to reference Figure 3 As can be seen, the battery voltage of the gas stove drops instantaneously from the state where the button is not pressed to the state where it is pressed. Therefore, the gas stove monitoring method provided in this embodiment of the invention sets a reasonable sampling period, and at set intervals, determines whether the gas stove button is in the pressed state based on the battery voltage values ​​of two adjacent samples, significantly improving the monitoring efficiency and accuracy of the gas stove.

[0066] In one alternative implementation, step S4021 may include:

[0067] Step a1: When the first difference between the first battery voltage value at the first moment and the second battery voltage value at the second moment is greater than the first threshold, the button is determined to be in the pressed state. Here, the second moment is later than the first moment, the second moment is spaced apart from the first moment by a set period, and the second battery voltage value is less than the first battery voltage value.

[0068] In one embodiment of the present invention, since the voltage change is minimal when the battery is fully charged and the button is pressed to ignite the gas stove, the voltage change increases as the battery level decreases. Therefore, when the battery is fully charged, the change in battery voltage from when the button is pressed to when it is pressed is detected, and a first threshold is set accordingly. In practical applications, to ensure accuracy and timeliness of the judgment, redundancy is usually considered, and the first threshold set for judging the button state as pressed is usually smaller than the actual measured battery voltage change value. For example, the value of the first threshold is A1. The gas stove controller can read the battery voltage value at millisecond intervals and, based on the change in battery voltage value, determine whether the difference between two adjacent battery voltage values ​​reaches A1. (Return to reference) Figure 3 The image shows the voltage change during a short period of time when a button is pressed and released. The horizontal axis is in milliseconds, and the vertical axis is in volts (V). Through actual measurement, assuming a fully charged battery, the voltage change when the button is pressed to start the ignition, compared to the voltage when the button is not pressed, is 0.09. Therefore, the value of the first threshold A1 can be less than 0.09; for example, A1 = 0.07.

[0069] The gas stove monitoring method provided in this invention determines that the button is in a pressed state when the first difference between the first battery voltage value at a first moment and the second battery voltage value at a second moment is greater than a first threshold. This method fully utilizes the characteristic that the battery voltage value drops instantaneously and continuously when the button is pressed and the gas stove is ignited, thus quickly and accurately determining the button's pressed state.

[0070] In an optional implementation, step S402 further includes:

[0071] Step S4022: Based on the two collected battery voltage values, determine whether the gas stove button is in the released state. The two collection times are any time after the second time.

[0072] For example, refer back to the reference. Figure 3Before the 80th millisecond, the battery voltage fluctuation is small, and the change in battery voltage does not reach the first threshold, so the button is not determined to be pressed. At the 90th millisecond, a voltage decrease is detected, and the difference between two adjacent battery voltage measurements is greater than the first threshold. Therefore, the gas stove button can be determined to be pressed at this time. Furthermore, after the 110th millisecond, a battery voltage rebound is detected. Thus, after determining that the gas stove button is pressed, the button's state can be further determined to be released based on the two collected battery voltage values. Since the rate of battery voltage rebound is slower than the rate of battery voltage drop when the button is pressed, the two data collection times are either the second time point or any time after the second time point. The second time point is the time when the button was determined to be pressed in the aforementioned steps.

[0073] In one optional implementation, step S4022 includes:

[0074] Step b1: When the first difference between the third battery voltage value at the third time and the second battery voltage value at the second time is greater than the second threshold, the button is determined to be in the released state. Here, the third time is later than the second time, and the first threshold is greater than the second threshold.

[0075] The gas stove monitoring method provided in this embodiment of the invention determines whether the gas stove button is in a released state based on two collected battery voltage values. It effectively judges the complete process of the button's state from being pressed to being released, which is beneficial for reasonable and effective monitoring of the gas stove.

[0076] Step S403: When it is determined that the state of the gas stove button has changed, a reminder is issued.

[0077] In an optional implementation, step S403 may include:

[0078] Step S4031: When the button is in the pressed state, issue the first reminder.

[0079] In step S4032, when the button is in the released state, a second reminder is issued.

[0080] For example, for gas stoves that require product function responses based on button presses, when a button press is detected, functions such as displaying certain icons, sounding a buzzer, or wirelessly sending a press signal may be used.

[0081] Here, the first and second reminders can be different icons, different buzzer sounds, or different wireless communication messages. This invention does not impose specific limitations on this.

[0082] It should be noted that steps S4031 and S4032 above can be configured to execute one or both steps according to actual needs.

[0083] The gas stove monitoring method provided in this invention provides an alert when it detects a change in the state of the gas stove's buttons, thus fully ensuring the safety and controllability of gas stove use.

[0084] This invention maintains the controller's ability to detect button presses through the aforementioned detection method, while effectively simplifying the connection lines and enhancing the reliability of the gas stove.
