Description

Technical Field

[0001] The present application relates to the technical field of data display of heat-not-burn appliances, and in particular to a method, system, terminal device and heat-not-burn appliance for displaying a temperature curve of a heating element. Background Art

[0002] When the heating-not-burning appliance is started, the heating element will be heated and controlled according to the stored target temperature curve, thereby baking the aerosol to generate the matrix. At present, the heating element is usually subjected to PID temperature control, where P represents proportional control, I represents integral control, and D represents differential control. When it is detected that the actual temperature of the heating element is much different from the target temperature, the current output power of the heating element is controlled by outputting power signals with different PWM duty cycles, so that the actual temperature of the heating element is as close to the target temperature as possible. When it is found that the PID temperature control effect is not good, the PID parameters of the appliance can be adjusted and the firmware can be recompiled and burned. However, the user cannot intuitively understand whether the current PID parameter adjustment can optimize the temperature control trend, that is, whether the actual temperature curve can be made closer to the target temperature curve after adjusting the PID parameters.

[0037] In the following description, for the purpose of illustration rather than limitation, specific details such as specific system structures, technologies, etc. are proposed, so as to thoroughly understand the embodiments of the present application. However, it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details. In other cases, the detailed description of well-known systems, devices, circuits and methods is omitted to prevent unnecessary details from hindering the description of the present application. In addition, in the description of the present application specification and the attached claims, the terms "first", "second", "third" etc. are only used to distinguish the description, and cannot be interpreted as indicating or suggesting relative importance.

[0038] Heat-not-burn appliances usually perform PID temperature control on the heating element, which can make the actual temperature of the heating element as close to the target temperature as possible. However, when the temperature control effect is not good and the PID parameters need to be adjusted, the user cannot intuitively understand whether the current PID parameter adjustment can optimize the temperature control trend. To address this problem, the embodiments of the present application provide a temperature curve display method, system, terminal device and heat-not-burn appliance for a heating element, which can enable the user to intuitively understand whether the current PID parameter adjustment can optimize the temperature control trend. For more specific technical implementation details of the embodiments of the present application, please refer to the various embodiments described below.

[0039] like Figure 1 , which is a schematic diagram of a temperature curve display system for a heating element provided in an embodiment of the present application. Figure 1 The system shown includes a terminal device and a heat-not-burn appliance, wherein the terminal device serves as a host computer, which may specifically be various types of devices such as a laptop computer, a tablet computer, a desktop computer, a mobile phone, a wearable device, a netbook, a personal digital assistant (PDA) or a large-screen TV; the heat-not-burn appliance serves as a slave computer, which may be an appliance of any type or model. Figure 2 It is a schematic diagram of the structure of a heating without burning device provided in an embodiment of the present application. Figure 2 The heating without burning appliance shown includes a control mainboard, a heating element and a battery module, and the control mainboard is electrically connected to the heating element and the battery module respectively. Among them, the heating without burning appliance can interact with the host computer through the control mainboard, obtain the PID parameters sent by the host computer and perform PID temperature control on the heating element. The heating element can be heated up under the control of the control mainboard to bake the aerosol generation matrix, and the battery module is used as a power source to provide electrical energy. The terminal device and the heating without burning appliance can establish a communication connection in various wired or wireless ways. As an example, a serial port line can be used to establish a communication connection, and one end of the serial port line is connected to the COM port of the terminal device, and the other end is connected to the control mainboard of the heating without burning appliance. The terminal device can interact with the heating without burning appliance and send the set PID parameters to the heating without burning appliance. The heating without burning appliance can perform PID temperature control on the heating element according to the sent PID parameters and record the corresponding actual temperature curve. After that, the terminal device can obtain the actual temperature curve and display it on the screen. About Figure 1 For the specific working principle of the system shown, please refer to the method embodiment described below.

[0040] See also Figure 3 , shows a method for displaying a temperature curve of a heating element provided in an embodiment of the present application, comprising:

[0041] 301. The terminal device sends the target PID parameter to the heating-not-burning appliance;

[0042] The terminal device is used as a host computer, and the heating-not-burning appliance is used as a slave computer. Before implementing the method provided in the embodiment of the present application, it is necessary to first establish a communication connection between the terminal device and the heating-not-burning appliance to complete data interaction. The terminal device and the heating-not-burning appliance can establish a communication connection through various wired or wireless methods such as a serial port line, a USB line, Bluetooth, and a network, and the embodiment of the present application does not limit this. As an example, a serial port line can be used to connect the terminal device and the heating-not-burning appliance, one end of the serial port line is connected to a COM port of the terminal device, and the other end is connected to the control motherboard of the heating-not-burning appliance. After the terminal device configures the corresponding channel number (i.e., the connected COM port number), a communication connection with the heating-not-burning appliance can be established, thereby completing data interaction.

[0043] In actual operation, an application software for adjusting PID temperature control parameters and displaying temperature curves can be pre-installed in the terminal device. Through the software interface of the application software, the user can perform various operations such as selecting a connection port, setting PID parameters to be sent to the device, reading the current PID parameters from the device, reading the target temperature curve from the device, reading the actual temperature curve from the device, setting the color of the curve display, viewing the displayed temperature curves, and viewing the PID parameters corresponding to each temperature curve.

[0044] As an example, Figure 4 The figure is a schematic diagram of a software interface provided by an embodiment of the present application. Figure 4The software interface shown includes different areas such as PID parameter input area, curve color setting area, channel number setting area, function selection area, historical PID parameter display area, curve display area and information display area. Among them, the PID parameter input area is used to input the PID parameters that need to be sent to the appliance, including parameter P, parameter I and parameter D; the curve color setting area is a drop-down box, which can be used to select the color of the actual temperature curve corresponding to the sent PID parameters when displayed in the software interface, such as black, blue and purple, etc.; the channel number setting area is used to select the corresponding channel number, for example, if the serial port line is connected to the COM3 of the terminal device and the heating but not burning appliance respectively, the channel number COM3 is selected to correctly establish the communication connection; the function selection area is used to select the operation that needs to be performed currently, which may include different operations such as importing parameters, reading parameters and reading from the device. Importing parameters is used to send the set PID parameters to the appliance, reading parameters is used to obtain the PID parameters currently used by the appliance, and can be displayed in the historical PID parameter display area accordingly, and reading from the device is used to obtain the temperature curves stored in the register flash of the appliance, which may include the target temperature curve and the actual temperature curve; the historical PID parameter display area is used to display the various groups of PID parameters that the appliance has used; the curve display area can be used to superimpose the target temperature curve and various different actual temperature curves; the information display area can be used to display the color and PID parameters corresponding to each actual temperature curve.

[0045] If the temperature control effect obtained by the PID parameters currently used by the heating without combustion appliance is not good, the user can modify the PID parameters through the above software interface of the terminal device. Specifically, the adjusted PID parameters can be entered as the target PID parameters in the PID parameter input area. By clicking "Import Parameters", the terminal device can send the target PID parameters to the heating without combustion appliance.

[0046] In one implementation of the embodiment of the present application, before the terminal device sends the target PID parameter to the heating non-combustion appliance, it also includes:

[0047] The terminal device determines the target PID parameters and curve colors set by the user through the software interface.

[0048] Through the above software interface, users can set the target PID parameters and corresponding curve colors that they want to send to the heating-not-burning appliance. Specifically, users can input parameters P (mainly used for heating slope), I (mainly used for error elimination) and D (mainly used for advance adjustment) in the PID parameter input area to determine the target PID parameters; click the drop-down box in the curve color setting area and select a color to determine the curve color. The curve color corresponds to the target PID parameter, and the actual temperature curve of the appliance obtained using the target PID parameter will be displayed in this curve color.

[0049] In one implementation of the embodiment of the present application, the terminal device can read the PID parameters currently used by the heating-without-combustion appliance and display the PID parameters on the software interface so that the user can easily view the PID parameters currently configured for the appliance. Specifically, when the user wants to obtain the PID parameters currently used by the heating-without-combustion appliance, after connecting the terminal device to the heating-without-combustion appliance and correctly selecting the channel number, click the "Read Parameters" button in the above software interface, so that the terminal device will read the currently used PID parameters stored in the register flash of the heating-without-combustion appliance and display the PID parameters in the historical PID parameter display area of ​​the software interface.

[0050] 302. The heating-not-burning appliance performs PID temperature control on the heating element according to the target PID parameter during the next heating, and records a first actual temperature curve of the heating element corresponding to the target PID parameter;

[0051] After receiving the target PID parameters sent by the terminal device, the heating non-combustion appliance will recompile and burn the firmware and store the target PID parameters in the register flash. In this way, the appliance will perform PID temperature control on the heating element according to the target PID parameters when heating next time, and record the actual temperature curve of the heating element corresponding to the target PID parameters in real time. The actual temperature curve is recorded as the first actual temperature curve.

[0052] The basis of PID temperature control is P proportional control, I integral control can be used to eliminate steady-state errors but may increase overshoot, and D differential control can speed up the response speed of large inertia systems and reduce overshoot trends. When the user presses the start button of the heating-not-burning appliance and the appliance starts to heat, the heating body will heat up at full power output, thereby minimizing the heating time. The heating module of the control mainboard will synchronously call the heating body temperature calculation function, calculate the actual temperature of the current heating body in real time to obtain the actual temperature curve, which can be stored in the register flash of the appliance for terminal equipment to read. When performing PID temperature control, if it is found that the difference between the actual temperature of the heating body and the target temperature exceeds a certain threshold (for example, 30°C), the current output power of the heating body can be controlled by outputting power signals with different PWM duty cycles, so that the actual temperature of the heating body is as close to the target temperature as possible, and the actual temperature curve coincides with the target temperature curve as much as possible.

[0053] In one implementation of the embodiment of the present application, the heating-without-combustion appliance performs PID temperature control on the heating element according to the target PID parameter during the next heating, including:

[0054] After receiving the target PID parameters sent by the terminal device, the heating non-combustion appliance feeds back the parameter reception success information to the terminal device and starts heating, and performs PID temperature control on the heating element according to the target PID parameters.

[0055] After receiving the target PID parameters sent by the terminal device, the heating-not-burning appliance can immediately feedback the terminal device with the parameter reception success information (for example, a corresponding character string) and automatically start heating, and perform PID temperature control on the heating element according to the target PID parameters. That is, the user does not need to manually press the start button, and the appliance adopts the self-starting mode, which can effectively simplify the user operation and improve the operational efficiency of PID parameter adjustment and implementation.

[0056] 303. The terminal device obtains a first actual temperature curve through the heating non-combustion device, and displays the first actual temperature curve on a software interface.

[0057] The terminal device can obtain the first actual temperature curve stored in the heating-without-combustion device and display the first actual temperature curve in the above software interface. In actual operation, the first actual temperature curve recorded by the heating-without-combustion device will be stored in the register flash. The user can click the "Read from Device" button in the function selection area of ​​the above software interface, so that the terminal device will read the first actual temperature curve stored in the register flash of the device and display the first actual temperature curve in the curve display area of ​​the above software interface. Since the target temperature curve of the heating-without-combustion device is known, the displayed first actual temperature curve can be compared with the target temperature curve to know whether the first actual temperature curve obtained by adjusting the PID parameters (i.e., the target PID parameters) is closer to the target temperature curve, so as to understand whether the current PID parameter adjustment can optimize the temperature control trend.

[0058] In one implementation of the embodiment of the present application, displaying the first actual temperature curve on the software interface includes:

[0059] The terminal device displays the first actual temperature curve in the curve color in the software interface.

[0060] When the user sets the target PID parameters issued through the above software interface, the user can also select the color of the actual temperature curve corresponding to the target PID parameters when displayed in the software interface. For example, if the user selects black, the first actual temperature curve is a black curve, if the user selects blue, the first actual temperature curve is a blue curve, and so on. Through this setting, the user can easily distinguish the actual temperature curves corresponding to different PID parameters according to the color of the curve.

[0061] In one implementation of the embodiment of the present application, the method further includes:

[0062] The terminal device displays the corresponding relationship information between the curve color and the target PID parameter in the information display area of ​​the software interface.

[0063] The above software interface also has an information display area, which can be used to display the color and PID parameters corresponding to each actual temperature curve. For example, if the actual temperature curve of the target PID parameter is a black curve, the corresponding relationship between black and the target PID parameter will be displayed in the information display area of ​​the software interface. If the actual temperature curve of the target PID parameter is a blue curve, the corresponding relationship between blue and the target PID parameter will be displayed in the information display area of ​​the software interface. Through this setting, users can intuitively view the PID parameters corresponding to the actual temperature curve of each color.

[0064] In one implementation of the embodiment of the present application, the method further includes:

[0065] (1) The terminal device obtains the target temperature curve of the heating element by heating the non-combustion device;

[0066] (2) The terminal device displays the target temperature curve on the software interface.

[0067] The heating-without-combustion appliance will pre-store the target temperature curve of the heating element. The terminal device can read the target temperature curve through the heating-without-combustion appliance and display the target temperature curve in the above software interface. Specifically, the target temperature curve is stored in the register flash of the heating-without-combustion appliance. The user can click the "Read from device" button in the above software interface, so that the terminal device will read the target temperature curve stored in the register flash of the appliance, and can display the target temperature curve in the curve display area of ​​the above software interface. As an example, the target temperature curve and the actual temperature curve can be superimposed and displayed simultaneously in the curve display area, so that the user can more intuitively view the difference between the actual temperature curve and the target temperature curve, and judge whether the currently adjusted PID parameters can make the actual temperature curve closer to the target temperature curve, that is, whether the temperature control direction can be optimized.

[0068] Figure 5 is a schematic diagram of an actual temperature curve and a target temperature curve superimposed and displayed in a software interface, provided in an embodiment of the present application, by Figure 5 It can be seen that the actual temperature curve and the target temperature curve are superimposed and displayed in the curve display area, and the user can intuitively view the difference between the actual temperature curve and the target temperature curve. Through the information display area at the bottom right of the software interface, the color (blue) corresponding to the actual temperature curve and the PID parameters (P = 25, I = 0.5, D = 30) can be viewed.

[0069] In an implementation of the embodiment of the present application, after the terminal device obtains the first actual temperature curve and the target temperature curve through the heating non-combustion appliance, it also includes:

[0070] (1) If the difference between the first actual temperature curve and the target temperature curve exceeds a set threshold, the terminal device adjusts the target PID parameter and sends the adjusted target PID parameter to the heating-not-burning appliance to obtain a second actual temperature curve of the heating element corresponding to the adjusted target PID parameter;

[0071] (2) The terminal device displays the target temperature curve, the first actual temperature curve, and the second actual temperature curve in a curve display area of ​​the software interface.

[0072] If the difference between the first actual temperature curve and the target temperature curve exceeds the set threshold, that is, the overlap of the two curves is low, it means that the effect of PID temperature control using the target PID parameters is not good, and the target PID parameters need to be adjusted. After adjusting the target PID parameters, the terminal device can send the adjusted target PID parameters to the heating-without-combustion appliance in the same way. The heating-without-combustion appliance will perform PID temperature control on the heating element according to the adjusted target PID parameters during the next heating, and record the actual temperature curve of the heating element corresponding to the target PID parameters in real time. The actual temperature curve is recorded as the second actual temperature curve. The second actual temperature curve is also stored in the register flash of the appliance. The user can click the "Read from device" button in the function selection area of ​​the above software interface, so that the terminal device will read the second actual temperature curve stored in the register flash of the appliance, and can display the second actual temperature curve in the curve display area of ​​the above software interface. Specifically, the terminal device can superimpose the target temperature curve, the first actual temperature curve and the second actual temperature curve in the curve display area of ​​the software interface, so that the user can more intuitively understand whether the current PID parameter adjustment can optimize the temperature control trend, and what specific impact the adjustment of a certain PID parameter will have on the actual temperature curve, etc. For example, if the second actual temperature curve is closer to the target temperature curve than the first actual temperature curve, it can be considered that the current adjustment of the target PID parameter is appropriate and can optimize the temperature control trend. On the contrary, if the second actual temperature curve deviates more from the target temperature curve than the first actual temperature curve, it can be considered that the current adjustment of the target PID parameter is inappropriate and will worsen the temperature control trend. It can be seen that the terminal device can set different PID parameters multiple times and send them to the heating-without-combustion appliance. The heating-without-combustion appliance performs heating once under each PID parameter to obtain a corresponding actual temperature curve, that is, the number of actual temperature curves corresponds to the number of heating times of the appliance. Assuming that N different PID parameters are set, the appliance can obtain N actual temperature curves after N heatings. The N actual temperature curves and the target temperature curve can be superimposed and displayed in the curve display area of ​​the software interface. Different actual temperature curves can be drawn in different colors for users to distinguish.

[0073] There are two implementation methods for adjusting the target PID parameters. The first is manual adjustment by the user: the user can modify the target PID parameters in a targeted manner according to the difference between the current actual temperature curve and the target temperature curve, and then input the modified target PID parameters through the PID parameter input area in the above software interface, and send it to the heating-not-burning appliance. The second is automatic adjustment. The terminal device can detect the specific difference between the current actual temperature curve and the target temperature curve, such as whether the actual temperature curve is higher or lower than the target temperature curve, whether the actual temperature curve has excessive curve fluctuations compared to the target temperature curve, and so on. Then, the terminal device can determine the appropriate modification direction based on the specific difference, and then automatically generate the adjusted target PID parameters, and send them to the heating-not-burning appliance. For example, if the terminal device detects that the actual temperature curve has excessive curve fluctuations compared to the target temperature curve, the parameter I in the target PID parameter can be appropriately lowered.

[0074] Figure 6 This is a schematic diagram of an embodiment of the present application that provides a superimposed display of two actual temperature curves and a target temperature curve in a software interface. Figure 6 It can be seen that the two actual temperature curves are superimposed on the target temperature curve and displayed in the curve display area. The black actual temperature curve corresponding to the PID parameters (P=20, I=0.5, D=80) is closer to the target temperature curve than the blue actual temperature curve corresponding to the PID parameters (P=25, I=0.5, D=30). That is, the temperature control effect of the PID parameters (P=20, I=0.5, D=80) is better, so it is determined that the PID parameter adjustment from (P=25, I=0.5, D=30) to (P=20, I=0.5, D=80) can optimize the temperature control trend.

[0075] In the technical solution of the embodiment of the present application, the terminal device interacts with the heating-without-combustion appliance as a host computer. The terminal device can send the adjusted target PID parameters to the heating-without-combustion appliance. The heating-without-combustion appliance will perform PID temperature control on the heating element according to the target PID parameters during the next heating, and record the first actual temperature curve of the heating element corresponding to the target PID parameters. Afterwards, the terminal device can obtain the first actual temperature curve through the heating-without-combustion appliance and display the first actual temperature curve in the software interface. Through such a setting, the user can intuitively view the actual temperature curve obtained after adjusting the PID parameters in the software interface of the terminal device, and by comparing whether it is closer to the target temperature curve of the appliance, it can be understood whether the current PID parameter adjustment can optimize the temperature control trend.

[0076] To facilitate understanding of the temperature curve display method of the heating element provided in the embodiment of the present application, an actual application scenario is listed below.

[0077] like Figure 7 FIG. 1 is a schematic diagram of the operation flow of the method for displaying the temperature curve of a heating element provided in an embodiment of the present application in an actual application scenario. Figure 7 In the application scenario shown, first connect the upper and lower computers, that is, establish a communication connection between the terminal device and the heating-without-combustion appliance. Specifically, you can use a serial port line to connect the COM port of the appliance and the terminal device, open the corresponding application software on the terminal device, and select the corresponding channel number through the software interface to complete the connection. By clicking the "Read Parameters" button in the software interface, you can obtain the PID parameters currently used by the heating-without-combustion appliance and display them in the historical PID parameter display area. By clicking the "Read from Device" button in the software interface, you can obtain the target temperature curve of the heating-without-combustion appliance and the actual temperature curve recorded by the heating-without-combustion appliance, and display them in the curve display area of ​​the software interface. By clicking the "Import Parameters" button in the software interface, the user can send the set PID parameters to the heating-without-combustion appliance, and in addition, the display color corresponding to the actual temperature curve can be selected through the curve color drop-down box. The appliance starts heating according to the sent PID parameters and records the current actual temperature curve. The terminal device can obtain the actual temperature curve and display the actual temperature curve in the curve display area of ​​the software interface with the corresponding color. Next, the difference between the current actual temperature curve and the target temperature curve can be compared to determine whether the two curves are highly overlapped. If they are highly overlapped, it means that the PID parameters currently used by the appliance are appropriate, and the PID parameters can be used to continue to control the temperature of the heating element of the appliance; if they are not highly overlapped, it means that the PID parameters currently used by the appliance are not appropriate. At this time, the heating of the appliance can be stopped, and the PID parameters can be reasonably adjusted according to the trend of the curve. By clicking the "Import Parameters" button on the software interface, the adjusted PID parameters can be sent to the heating-not-burning appliance. The heating-not-burning appliance will control the temperature of the heating element according to the adjusted PID parameters during the next heating, thereby obtaining the actual temperature curve corresponding to the adjusted PID parameters, and repeating the same process. Obviously, through such a setting, the user can use the software interface of the terminal device to intuitively view the actual temperature curves corresponding to each adjusted PID parameter, compare the difference between these actual temperature curves and the target temperature curve, and accurately determine whether the current PID parameter adjustment can optimize the temperature control trend.

[0078] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution.
