Description

TECHNICAL FIELD

[0001] The present application relates to the field of parameter control, and more particularly, to a PID parameter control device, method, equipment and storage medium of a heating non-combustion appliance. BACKGROUND

[0002] In the field of heating non-combustion appliances, with the wide application of such products in the market, the optimization of their working performance has attracted high attention. During the operation of these appliances, temperature control is a crucial link, which directly affects the use effect and user experience of the products.

[0003] At present, the heating non-combustion appliance generally adopts PID algorithm to adjust the temperature during work, so that the appliance can stably run at the set temperature. PID algorithm can effectively regulate and control the temperature in theory, but in actual application, due to the obvious differences in structure, heating body and other aspects of the heating non-combustion appliances involved in different projects, the key parameters such as heat transfer characteristics and thermal inertia of each appliance are different. This means that the PID parameters need to be adjusted separately for different appliances. In actual operation, this adjustment process is extremely tedious, and technicians need to spend a lot of time and effort to adjust the parameters one by one.

[0004] Since the debugging work depends on manual operation, manual adjustment is often limited by the experience, skill level and environmental factors of the operator, and it is difficult to accurately determine the optimal PID parameter value, so that the temperature control is not accurate enough, resulting in uneven heating, local overheating or large temperature fluctuations of the heating non-combustion appliance, and thus reducing the quality and reliability of the product.

[0058] The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0059] The scheme of the present application can be implemented based on a terminal with data processing capability, which can be a computer, a cloud, a server, etc.

[0060] Next, the technical solutions in the embodiments of the present application will be described in detail with reference to the drawings.Figure 1 The PID parameter control method of the heating non-combustion appliance can include the following steps:

[0061] Step S1: In the PID parameters for controlling the heating non-combustion appliance, one of the parameters that has not been modified is selected as a new target parameter, the parameter range corresponding to the target parameter value is obtained, the middle value of the parameter range is taken as a temporary modification value, the heating non-combustion appliance is heated, and the temperature difference between the current temperature of the heating non-combustion appliance and the preset temperature is calculated.

[0062] It can be understood that the PID parameters include three parameters (P, I, and D), and the temperature of the appliance will be different after the value of any one of the three parameters is changed. Therefore, the three parameters need to be optimized and adjusted to stabilize the temperature control of the appliance.

[0063] Specifically, the PID parameter control method can be to control the target parameters one by one, so the parameters that have been controlled do not need to be taken as target parameters, and the uncontrolled parameters can be selected as target parameters for control.

[0064] For example, the parameter range corresponding to the P value is 10-300, and the middle value of the parameter range is 155. Therefore, 155 can be taken as a temporary modification value. After the heating non-combustion appliance is heated using the P value, the actual temperature is recorded and compared with the preset temperature to calculate the temperature difference.

[0065] Step S2: Update the parameter range based on the temporary modification value to obtain a new parameter range.

[0066] The new parameter range is a subset of the parameter range before updating.

[0067] Specifically, the temporary modification value can be taken as one boundary of the new parameter range. For example, the parameter range corresponding to the P value is 10-300, and 155 is taken as a temporary modification value. The new parameter range can be 155-300 or 0-155. Whether it is 155-300 or 0-155, it belongs to the subset of 10-300.

[0068] Step S3: Select a new temporary modification value from the parameter range, based on the temperature of the heating non-combustion appliance after being heated at the temporary modification value and the temperature difference, narrow the parameter range, and when the span of the parameter range after being narrowed is not greater than a preset span threshold, determine the final control value of the target parameter.

[0069] Specifically, after the second time of heating the appliance, the temperature difference between the current temperature and the preset temperature is calculated again, and the temperature differences before and after are compared, and the parameter range is further reduced according to the temperature differences before and after. The way to reduce the parameter range can be based on the size change relationship of the temperature differences before and after, such as fixing the lower limit of the parameter range and reducing half of the parameter range if the temperature difference is larger than the last time, and fixing the upper limit of the parameter range and reducing half of the parameter range if the temperature difference is smaller than the last time.

[0070] It can be understood that the preset span threshold value can represent the degree that any determination of the control value in the parameter range does not cause a significant change in the temperature difference, so when the span after the parameter range is reduced is not greater than the preset span threshold value, the final control value of the target parameter can be determined.

[0071] Step S4: determining whether there is an uncompleted modified parameter in the PID parameter, if yes, returning to execute step S1, if not, completing the modification of the PID parameter and saving each final control value of the PID parameter, and stopping heating the heat-not-burn appliance.

[0072] The PID parameter control method of the heat-not-burn appliance provided in the embodiment determines the parameter range in each PID parameter of the heat-not-burn appliance, selects the middle value in the parameter range to heat the appliance, obtains the temperature of the appliance, calculates the initial temperature difference between the temperature of the appliance and the preset temperature, reduces the parameter range, selects the middle value again to heat the appliance, compares the size of the temperature differences and reduces the parameter range again, so that when the span after the parameter range is reduced is not greater than the preset span threshold value, the final control value is determined. As can be seen, for each PID parameter of the heat-not-burn appliance, the parameter range is continuously reduced, and at the same time, the temperature difference after the parameter range is reduced each time is as small as possible, so that the final control value of the PID parameter in the parameter range with a very small span is quickly determined, and the efficiency and accuracy of the temperature control of the heat-not-burn appliance are improved.

[0073] In some embodiments of the present application, the process of step S3: selecting a new temporary modification value from the parameter range, reducing the parameter range based on the temperature of the heat-not-burn appliance after heating at the temporary modification value and the temperature difference, and determining the final control value of the target parameter when the span after the parameter range is reduced is not greater than the preset span threshold value is introduced as shown in Figure 2 The process can include:

[0074] Step S31: taking the middle value of the parameter range as a new temporary modification value, heating the heat-not-burn appliance, and calculating the temperature difference between the current temperature of the heat-not-burn appliance and the preset temperature.

[0075] For example, when the latest parameter range of P value is 155-300, the intermediate value is 227.5, and then P value = 227.5 can be taken as a new temporary modification value, the heat-not-burn appliance is heated, and then the temperature difference between the current temperature of the heat-not-burn appliance after heating and the preset temperature is calculated again.

[0076] Step S32: Based on the temperature difference and the temperature difference after the previous adjustment of the target parameter, the parameter range is narrowed and updated to obtain a new parameter range.

[0077] It can be understood that since the appliance is heated twice by the P value, two temperature differences are generated before and after, and then the two temperature differences before and after can be compared, and then the new parameter range is determined according to the comparison result.

[0078] Specifically, if the temperature difference is less than the temperature difference after the previous adjustment of the target parameter, the temporary modification value is taken as the lower limit of the parameter range, and the upper limit of the parameter range is taken as the upper limit of the parameter range, to determine the new parameter range.

[0079] For example, if the temperature difference is less than the temperature difference after the previous adjustment of the target parameter, the current temporary modification value 227.5 of the P value can be taken as the lower limit of the parameter range, and the upper limit (300) of the parameter range 155-300 can be taken as the upper limit of the parameter range, to obtain a new parameter range of 227.5-300.

[0080] If the temperature difference is greater than the temperature difference after the previous adjustment of the target parameter, the temporary modification value is taken as the upper limit of the parameter range, and the upper limit of the parameter range is taken as the lower limit of the parameter range, to determine the new parameter range.

[0081] For example, if the temperature difference is greater than the temperature difference after the previous adjustment of the target parameter, the current temporary modification value 227.5 of the P value can be taken as the upper limit of the parameter range, and the lower limit (155) of the parameter range 155-300 can be taken as the lower limit of the parameter range, to obtain a new parameter range of 155-227.5.

[0082] Step S33: Determine whether the span of the parameter range is greater than a preset span threshold, if yes, return to execute step S31, and if no, execute step S34.

[0083] Specifically, the preset span threshold can be determined according to the specific PID parameter, and the preset span threshold of different PID parameters can be different, for example, the preset span threshold corresponding to the P value can be 5.

[0084] Step S34: Determine that the temporary modification value is the final control value of the target parameter.

[0085] It can be understood that when the target parameter is found through multiple range narrowing, the temperature difference between the temperature of the heating appliance after the target parameter obtains the current temporary modification value and the preset temperature tends to be stable, and therefore the temporary modification value can be determined as the final control value of the target parameter.

[0086] The PID parameter control method for the heat-not-burn appliance provided by the embodiment can quickly and accurately find the control value of the target parameter that tends to stabilize the temperature for the heating working condition by continuously narrowing the parameter range of the target parameter, selecting the control value in the parameter range, and performing the heating test.

[0087] Considering that there are two directions for updating the parameter range of the target parameter before the second heating of the appliance, some embodiments of the present application further introduce the process of step S2: the temperature difference between the temperature of the heating appliance after the target parameter obtains the current temporary modification value and the preset temperature tends to be stable, which can include the following two cases:

[0088] First, the temporary modification value is used as the lower limit of the parameter range, and the upper limit of the parameter range is used as the upper limit of the parameter range to determine a new parameter range.

[0089] For example, the initial range of P value is 10-300, and the temporary modification value is 155. Then, the upper limit 300 of the range 10-300 can be used as the lower limit of the parameter range, and 155 can be used as the lower limit of the parameter range to determine a new parameter range of 155-300.

[0090] Second, the temporary modification value is used as the upper limit of the parameter range, and the lower limit of the parameter range is used as the lower limit of the parameter range to determine a new parameter range.

[0091] For example, the initial range of P value is 10-300, and the temporary modification value is 155. Then, the lower limit 10 of the range 10-300 can be used as the lower limit of the parameter range, and 155 can be used as the upper limit of the parameter range to determine a new parameter range of 10-155.

[0092] It can be understood that since the heating appliance cannot be determined in which parameter range tends to be stable after being heated in any one of the two cases, the heating appliance can be heated in both cases, and then the temperature after heating is compared with the preset temperature to obtain the temperature difference corresponding to the two cases, and then the case with smaller temperature difference is selected as the required step.

[0093] In some embodiments of the present application, in the step S1 of selecting one of the unmodified parameters as a new target parameter, obtaining the parameter range corresponding to the target parameter value, taking the middle value of the parameter range as a temporary modification value, heating the heating non-combustion appliance, and calculating the temperature difference between the current temperature and the preset temperature of the heating non-combustion appliance, the process of heating the heating non-combustion appliance is introduced, which can include:

[0094] In response to the start debugging instruction of the heating non-combustion appliance, in the PID parameter for controlling the heating non-combustion appliance, one of the unmodified parameters is selected as a new target parameter, the parameter range corresponding to the target parameter value is obtained, the middle value of the parameter range is taken as a temporary modification value, the heating non-combustion appliance is heated, and the temperature difference between the current temperature and the preset temperature of the heating non-combustion appliance is calculated.

[0095] Specifically, the PID parameter control process of the heating non-combustion appliance can be triggered to execute by a key or a serial port custom instruction. When the heating non-combustion appliance needs to be adjusted, the user can press the key to send a start debugging instruction of the heating non-combustion appliance to the terminal, so that the heating non-combustion appliance starts debugging, thereby eliminating the need for manual adjustment and waiting for the completion of the debugging to obtain the optimal PID parameter.

[0096] In order to improve the user experience of the PID parameter debugging control function, the PID parameter control method of the heating non-combustion appliance provided by the present application can further include:

[0097] When the modification of the PID parameter is completed, the indicator light flashes to inform the user that the PID parameter of the heating non-combustion appliance has been debugged and modified.

[0098] It can be understood that the user can be prompted by the flashing indicator light without manually checking whether the PID parameter debugging process is completed, thereby improving the user experience of the PID parameter debugging control function.
