Description

Technical Field

[0001] The present application relates to the field of parameter control, and more specifically, to a PID parameter control device, method, equipment and storage medium for a heating-not-burning appliance. Background Art

[0002] In the field of heat-not-burn appliances, with the wide application of such products in the market, the optimization of their working performance has received great attention. In the operation of these appliances, temperature control is a crucial link, which directly affects the product's use effect and user experience.

[0003] At present, when heating-not-burning appliances are working, PID algorithms are generally used to adjust the temperature so that the appliances can operate stably at the set temperature. In theory, the PID algorithm can effectively regulate the temperature, but in actual applications, due to the obvious differences in structure, heating elements, etc. of heating-not-burning appliances involved in different projects, the key parameters such as heat transfer characteristics and thermal inertia of each appliance are different. This means that for different appliances, PID parameters need to be debugged separately. In actual operation, this debugging process is extremely cumbersome, and technicians need to spend a lot of time and energy to adjust the parameters one by one.

[0004] Since debugging work relies on manual labor, manual debugging is often limited by various conditions such as operator experience, skill level and environmental factors. It is difficult to accurately determine the optimal PID parameter value, which leads to inaccurate temperature control, uneven heating of heating non-combustion appliances, local overheating or large temperature fluctuations, thereby reducing product quality and reliability.

[0058] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0059] The present application solution can be implemented based on a terminal with data processing capabilities, which can be a computer, cloud, server, etc.

[0060] Next, combine Figure 1 The PID parameter control method of the heating-not-burning appliance of the present application may include the following steps:

[0061] Step S1: Among the PID parameters used to control the heat-without-combustion appliance, one of the parameters that has not been modified is selected as a new target parameter, and a parameter range corresponding to the target parameter value is obtained. The middle value of the parameter range is used as a temporary modification value, the heat-without-combustion appliance is heated, and the temperature difference between the current temperature of the heat-without-combustion appliance and the preset temperature is calculated.

[0062] It is understandable that the PID parameters include three parameters (P, I and D). When the value of any of these three parameters changes, the temperature of the heating device will be different. Therefore, these three parameters need to be optimized and adjusted to ensure stable temperature control of the device.

[0063] Specifically, the PID parameters may be regulated by regulating the target parameters one by one, so that the parameters that have been regulated no longer need to be used as target parameters, while the parameters that have not been regulated may be selected as target parameters for regulation.

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

[0065] Step S2: updating 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 the update.

[0067] Specifically, the temporary modification value can be used as one of the boundaries of the new parameter range. For example, if the parameter range corresponding to the P value is 10-300, and 155 is used as the temporary modification value, the new parameter range can be 155-300 or 0-155. Both 155-300 and 0-155 belong to the subset of 10-300.

[0068] Step S3: Select a new temporary modification value from the parameter range, narrow the parameter range based on the temperature of the heating without burning appliance after heating under the temporary modification value and the temperature difference, and determine the final control value of the target parameter when the span of the narrowed parameter range is not greater than the preset span threshold.

[0069] Specifically, after heating the appliance for the second time, the temperature difference between the current temperature and the preset temperature can be calculated again, and then the temperature difference between the two times can be compared. The parameter range can be further narrowed according to the temperature difference between the two times. The method of narrowing the parameter range can be based on the relationship between the size changes of the temperature difference between the two times. If the temperature difference is larger than the previous time, the lower limit of the parameter range is fixed and the parameter range is narrowed by half. If the temperature difference is smaller than the previous time, the upper limit of the parameter range is fixed and the parameter range is narrowed by half.

[0070] It can be understood that the preset span threshold can indicate the extent to which any control value can be determined within the parameter range without causing a significant change in the temperature difference. Therefore, when the span after the parameter range is narrowed is not greater than the preset span threshold, the final control value of the target parameter can be determined.

[0071] Step S4: Determine whether there are any parameters in the PID parameters that have not been modified. If so, return to execute step S1. If not, complete the modification of the PID parameters and save the final control values ​​of the PID parameters, and stop heating the heating burner.

[0072] The PID parameter control method of the heating-without-burning appliance provided in this embodiment determines the parameter range in each PID parameter of the heating-without-burning appliance, selects the middle value in the parameter range to heat the appliance, obtains the appliance temperature, and calculates the initial temperature difference between the appliance temperature and the preset temperature, and then narrows the parameter range, selects the middle value again to heat the appliance, compares the size of the two temperature differences and narrows the parameter range again, so that the span after the parameter range is narrowed is not greater than the preset span threshold, and then determines the final control value. It can be seen that for each PID parameter of the heating-without-burning appliance, the parameter range is continuously narrowed, and the temperature difference after each narrowing of the parameter range is made as small as possible, and the final control value of the PID parameter within the extremely small span parameter range is quickly determined, thereby improving the efficiency and accuracy of the temperature control of the heating-without-burning appliance.

[0073] In some embodiments of the present application, the above step S3: selecting a new temporary modification value from the parameter range, narrowing the parameter range based on the temperature of the heating-not-burning appliance after heating under the temporary modification value and the temperature difference, and determining the final control value of the target parameter when the span of the narrowed parameter range is not greater than the preset span threshold value is introduced, such as Figure 2 As shown, the process may include:

[0074] Step S31: using the middle value of the parameter range as a new temporary modification value, heating the heating without combustion appliance, and calculating the temperature difference between the current temperature of the heating without combustion appliance and the preset temperature.

[0075] For example, when the latest parameter range of the P value is 155-300, the middle value is 227.5, then the P value = 227.5 can be used as a new temporary modification value to heat the heating without burning appliance, and then the temperature difference between the current temperature after the heating without burning appliance and the preset temperature is calculated again.

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

[0077] It is understandable that since the device is heated twice through two P values, two temperature differences are generated before and after, so the two temperature differences before and after can be compared, and then the new parameter range can be determined based on the comparison result.

[0078] Specifically, if the temperature difference is less than the temperature difference after the target parameter was last adjusted, the temporary modified 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.

[0079] For example, if the temperature difference is less than the temperature difference after the target parameter was last adjusted, the current temporary modification value of the P value 227.5 can be used as the lower limit of the parameter range, and the upper limit (300) of the parameter range 155-300 can be used as the upper limit of the parameter range, resulting in a new parameter range of 227.5-300.

[0080] If the temperature difference is greater than the temperature difference after the target parameter was last adjusted, the temporary modified value is used as the upper limit of the parameter range, and the upper limit of the parameter range is used as the lower limit of the parameter range to determine a new parameter range.

[0081] For example, if the temperature difference is greater than the temperature difference after the target parameter was last adjusted, the current temporary modification value of the P value 227.5 can be used as the upper limit of the parameter range, and the lower limit (155) of the parameter range 155-300 can be used as the lower limit of the parameter range, resulting in 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 so, return to execute step S31, if not, execute step S34.

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

[0084] Step S34: Determine the temporary modified value as the final control value of the target parameter.

[0085] It is understandable that after multiple range reductions, it can be found that the temperature difference between the temperature of the heating device and the preset temperature after the target parameter obtains the current temporary modification value tends to be stable, so the temporary modification value can be determined as the final control value of the target parameter.

[0086] The PID parameter control method for a heating-not-burning appliance provided in this embodiment can quickly and accurately find the control value that makes the target parameter tend to a stable temperature for the heating condition by continuously narrowing the parameter range of the target parameter to select a control value within the parameter range for a heating test.

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

[0088] The first method is to use the temporary modified value as the lower bound of the parameter range and the upper bound of the parameter range as the upper bound of the parameter range to determine the new parameter range.

[0089] For example, if the initial range of the P value is 10-300 and the temporary modification value is 155, then the upper limit 300 of 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 the new parameter range to be 155-300.

[0090] The second method is to use the temporary modified value as the upper limit of the parameter range and the lower limit of the parameter range as the lower limit of the parameter range to determine the new parameter range.

[0091] For example, if the initial range of the P value is 10-300 and the temporary modification value is 155, then the lower limit 10 of 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 the new parameter range to be 10-155.

[0092] It is understandable that since it is not possible to determine within which parameter range the device tends to be stable after selecting any one of the situations to heat the device, the device can be heated for both situations, and then the heated temperature can be compared with the preset temperature to obtain the temperature difference corresponding to the two situations, and then the situation with the smaller temperature difference can be selected as the step to be executed.

[0093] In some embodiments of the present application, the above step S1: in the PID parameters used to control the heating without burning appliance, one of the parameters that has not been modified is selected as a new target parameter, a parameter range corresponding to the target parameter value is obtained, and the middle value of the parameter range is used as a temporary modification value. The heating without burning appliance is heated, and the temperature difference between the current temperature of the heating without burning appliance and the preset temperature is calculated. The process is introduced, and the process may include:

[0094] In response to a start debugging instruction for the heat-not-burning appliance, among the PID parameters used to control the heat-not-burning appliance, one of the parameters that has not been modified is selected as a new target parameter, and a parameter range corresponding to the target parameter value is obtained. The middle value of the parameter range is used as a temporary modification value, the heat-not-burning appliance is heated, and the temperature difference between the current temperature of the heat-not-burning appliance and the preset temperature is calculated.

[0095] Specifically, the PID parameter control process of the heating without burning device can be triggered and executed by a button or a custom serial port command. When the heating without burning device needs to adjust the PID parameters, the user can press a button to send a start debugging command of the heating without burning device to the terminal, so that the heating without burning device starts debugging, thereby eliminating the need for manual adjustment and waiting for the debugging to complete to obtain the optimal PID parameters.

[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 in the present application may also include:

[0097] When the modification of the PID parameters is completed, the prompt light flashes to inform the user that the PID parameters of the heating and burner have been debugged and modified.

[0098] It is understandable that by prompting the user by means of a flashing indicator light, the user can know whether the PID parameter debugging process is completed without the need for the user to manually check, thereby improving the user experience of the PID parameter debugging control function.

[0099] The following is a description of a device for implementing PID parameter control of a heating without burning appliance provided in an embodiment of the present application. The device for implementing PID parameter control of a heating without burning appliance described below and the method for implementing PID parameter control of a heating without burning appliance described above can be referenced to each other.
