Abstract
Description
Technical Field
[0001] This invention relates to the field of moxibustion equipment technology, specifically to a method, system, and storage medium for controlling the burning speed of moxa sticks. Background Technology
[0002] Moxibustion is an important component of traditional Chinese medicine. It involves stimulating acupoints on the body with the heat and medicinal properties generated by burning moxa sticks to warm and unblock the meridians, and to strengthen the body's resistance and expel pathogenic factors. The burning speed of the moxa stick directly determines the temperature and therapeutic effect during moxibustion, and is a key factor influencing its efficacy.
[0003] Currently, most moxibustion devices on the market (such as moxibustion boxes and moxibustion instruments) have very crude control over the burning speed. Common methods include: Ventilation adjustment: The oxygen supply is changed by manually opening and closing the ventilation holes on the device, thus roughly affecting the combustion rate. This method relies on user experience, is difficult to control precisely, and has a delayed response.
[0004] Fixed wind speed: A small fan provides a constant airflow, which cannot be dynamically adjusted according to the actual burning state of the moxa stick.
[0005] The above control methods all lack real-time monitoring of the moxa stick's combustion status. All controls are open-loop and cannot cope with combustion fluctuations caused by factors such as uneven moxa stick material and environmental changes. Secondly, manual or fixed-mode control methods cannot achieve stable and precise maintenance of the combustion speed, resulting in fluctuating moxibustion temperatures, affecting efficacy, and even posing a risk of burns. Finally, they cannot be linked with specific moxibustion treatment plans (such as the different heat stimulation intensities required for tonifying and reducing methods), and cannot achieve personalized and precise moxibustion treatment. Summary of the Invention
[0006] In view of this, in order to overcome the defects of the above-mentioned technology, the present invention provides a method, system and storage medium for controlling the burning speed of moxa sticks, so as to solve the technical problems of the existing technology that the control of moxibustion operation is rough, relies on manual labor and cannot accurately maintain the optimal burning state.
[0007] The technical solution of the present invention is as follows: The first objective of this invention is to provide a method for controlling the burning speed of moxa sticks, comprising the following steps: S1: Real-time combustion state information of the target moxa stick's burning area is acquired using a thermal imaging camera. This combustion state information includes the area of the burning surface. Maximum temperature and temperature distribution characteristics ; S2: Based on the combustion state information, calculate the current combustion rate using a pre-established combustion rate model. And determine the target combustion rate. 目 Deviation; The pre-established combustion rate model is as follows:
[0008] in, It is the current combustion rate. The combustion surface area is obtained through thermal imaging. It is the highest temperature of the combustion surface obtained through thermal imaging. It is a characteristic of temperature distribution. , , , These are model parameters; S3: Based on the deviation, generate control commands to adjust at least one combustion environment parameter acting on the target moxa stick, thereby controlling the combustion speed of the target moxa stick.
[0009] Furthermore, in step S2, the temperature distribution characteristics To calculate the standard deviation of pixel temperature within the combustion region:
[0010] in: It is the temperature of each pixel. It is the average temperature. It refers to the number of pixels.
[0011] Furthermore, in step S3, the adjustment of at least one combustion environment parameter acting on the target moxa stick specifically includes: Selectively adjust the air supply parameters of the air supply device and / or the mechanical pressure of the pressure application device; wherein the air supply parameters include at least one of wind force and wind direction.
[0012] Furthermore, in step S3, generating control commands based on the deviation specifically includes: S 31 The deviation is input to the proportional-integral-derivative controller to obtain the control quantity; S 32 : Generate control commands for adjusting the power of the air supply device and / or the pressure of the pressure application device based on the control quantity.
[0013] Furthermore, in step S3, when the deviation cannot be effectively corrected by adjusting the air supply parameters, the pressure application device is activated to apply controllable mechanical pressure to the unburned part of the moxa stick.
[0014] Furthermore, prior to step S1, the following steps are also included: S0: Receives the target burning speed setting value input by the user, or automatically matches the corresponding target burning speed based on the moxibustion treatment plan selected by the user.
[0015] A second objective of this invention is to provide a moxa stick burning speed control system for executing the moxa stick burning speed control method described above, the system comprising: The status monitoring module is used to acquire real-time combustion status information of the target moxa stick's burning area; The processing and control module is communicatively connected to the status monitoring module and is used to determine the current combustion speed and the deviation from the target combustion speed based on the combustion status information, and generate control commands based on the deviation. The execution module, which is communicatively connected to the processing and control module, is used to adjust at least one combustion environment parameter acting on the target moxa stick in response to the control command.
[0016] Furthermore, the status monitoring module is a thermal imaging camera; the processing and control module includes a processor and a memory, the memory stores a computer program, and the processor executes the computer program to implement the steps of the method described above; the execution module is an air supply device, used to change the wind force blowing towards the target moxa stick according to the control command.
[0017] Furthermore, the execution module also includes a pressure application device, which includes a stepper motor and a high-temperature resistant pressure plate connected to the stepper motor; the processing and control module is also used to generate a pressure control command when it is determined that the current combustion speed exceeds the target combustion speed and cannot be effectively corrected by adjusting the air supply device; the stepper motor responds to the pressure control command and drives the high-temperature resistant pressure plate to apply controllable mechanical pressure to the unburned part of the moxa stick.
[0018] A third objective of the present invention is to provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the method described above.
[0019] Compared with the prior art, the present invention has at least the following beneficial effects: The moxa stick burning speed control method in this invention uses a thermal imaging camera to simultaneously acquire the burning surface area A and the highest temperature T. maxThe temperature distribution characteristic (D) breaks through the limitations of traditional single parameters (such as measuring only temperature). The combination of these three factors upgrades the system's perception of the combustion state from a single dimension to a three-dimensional system, laying the foundation for subsequent precise control. The pre-established combustion rate model directly maps the physical characteristics of the combustion state (area, temperature) to the numerical value of the combustion rate, transforming the combustion rate from an empirical description into a calculable quantitative indicator. When the combustion rate deviates from the target value, the system automatically adjusts environmental parameters (such as increasing wind speed to reduce combustion rate, or decreasing pressure to increase combustion rate) without manual intervention, ensuring that the combustion rate remains stable within the target range and can cope with environmental disturbances (such as airflow). The system dynamically adjusts the burning speed to maintain consistency, taking into account variations in temperature and the inherent differences in moxa sticks (such as uneven density and composition fluctuations). This is particularly suitable for moxibustion treatment scenarios where high precision in heat output is required. The stable burning speed ensures uniform heat output during moxibustion, avoiding fluctuations in therapeutic effects caused by inconsistent burning speed (such as inconsistent intensity of acupoint stimulation). Automated control replaces traditional manual observation and adjustment, reducing the workload of moxibustion practitioners and enabling standardized moxibustion for ordinary users (home use). By monitoring the burning status in real time (such as local high temperature warnings), timely adjustments can be made to avoid risks such as burns and fires, thus improving the safety of the moxibustion process.

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0023] Figure 1 The image shows a method for controlling the burning speed of an moxa stick according to an embodiment of the present invention. The method includes the following steps: S1: Real-time combustion state information of the target moxa stick's burning area is acquired using a thermal imaging camera. This combustion state information includes the area of the burning surface. Maximum temperature and temperature distribution characteristics .
[0024] In this step, a thermal imaging camera is selected as the sensing device, which can simultaneously capture three core types of information: combustion surface area, maximum temperature, and temperature distribution characteristics. Real-time acquisition ensures data timeliness and avoids control inaccuracies due to information lag, providing a dynamic and continuous data source for subsequent calculations and adjustments.
[0025] S2: Based on the combustion state information, calculate the current combustion rate using a pre-established combustion rate model. And determine the target combustion rate. Deviation; The pre-established combustion rate model is as follows:
[0026] in, It is the current combustion rate. The combustion surface area is obtained through thermal imaging. It is the highest temperature of the combustion surface obtained through thermal imaging. It is a characteristic of temperature distribution. , , , These are model parameters.
[0027] In this step, the combustion rate model is constructed through multi-parameter coupling (area, maximum temperature, temperature distribution), overcoming the limitations of judging based on a single parameter (such as temperature alone), and better reflecting the complex physical process of moxa stick combustion. The model incorporates adjustable parameters that can be calibrated using experimental data to adapt to moxa sticks of different specifications and compositions, improving the versatility of the solution. Deviation calculation is directly linked to the current state and target requirements, providing clear quantitative basis for subsequent control commands and avoiding blind adjustments.
[0028] S3: Based on the deviation, generate control commands to adjust at least one combustion environment parameter acting on the target moxa stick, thereby controlling the combustion speed of the target moxa stick.
[0029] In this step, control commands are generated based on the deviation, forming a closed-loop control logic of acquisition, calculation, and adjustment to ensure timely response when a deviation occurs.
[0030] This control method utilizes multi-dimensional combustion state information and a quantitative model to make the calculation of combustion speed more closely match the actual situation and the judgment of deviations more accurate. The closed-loop adjustment mechanism can correct deviations in real time, preventing the combustion speed from deviating from the target value, solving the problem of inconsistent burning speed of traditional moxa sticks, and ensuring the consistency of moxibustion treatment. The thermal imaging acquisition method is not affected by environmental interference such as smoke and light, and is suitable for complex moxibustion scenarios (such as inside a moxibustion box or in different room temperature environments). The model parameters are calibrable and the adjustment dimensions are selectable, making it compatible with moxa sticks of different diameters, moxa wool purity, and added medicinal materials, and compatible with more different scenarios. In addition, the entire process of sensing, calculation, and adjustment can be completed automatically, without the need for frequent manual adjustment of the moxa stick position and environmental conditions, reducing the operation threshold. Dynamic adjustment can cope with sudden environmental changes (such as sudden wind or sudden changes in ambient temperature), automatically canceling interference factors, maintaining a stable combustion speed, and improving the reliability of the moxibustion experience.
[0031] Specifically, in step S2, the temperature distribution characteristics To calculate the standard deviation of pixel temperature within the combustion region:
[0032] in, It is the temperature of each pixel. It is the average temperature. It refers to the number of pixels.
[0033] Specifically, in this embodiment, the temperature of each pixel within the combustion area is first obtained. The average value T of these temperatures is calculated, and then the dispersion of temperature within the combustion zone is quantified by a formula. This process transforms the temperature distribution of the combustion zone from a qualitative description into a quantitative indicator, providing calculable input parameters for the combustion rate model.
[0034] Understandably, the temperature distribution characteristic D (standard deviation) describes the temperature dispersion of the combustion zone from a statistical perspective, supplementing the deficiencies of "maximum temperature" (single-point extreme value) and "combustion surface area" (geometric dimension). For example, if two moxa sticks have the same combustion surface area and maximum temperature, but one has fluctuating temperatures within its combustion zone (large D) while the other has a uniform temperature (small D), their combustion speeds and stability will inevitably differ. By introducing the temperature distribution characteristic D, the model can more accurately distinguish these differences, making the calculation of combustion speed more closely reflect the actual physical process.
[0035] When the temperature distribution characteristic D is large, it indicates that the temperature in the combustion area is uneven, and there may be local "hot spots" of rapid combustion or "cold spots" of slow combustion. At this time, the deviation in the model calculation will drive the control command to adjust the combustion environment parameters (such as adjusting the local oxygen supply and wind speed) to eliminate the uneven temperature and avoid fluctuations in the combustion speed.
[0036] By continuously monitoring and adjusting the temperature distribution characteristic D, the temperature distribution on the burning surface of the moxa stick can be made more uniform, and the overall burning speed of the moxa stick can be more consistent. This is crucial for scenarios such as moxibustion treatment (which requires stable heat output) and can improve the consistency of treatment effects.
[0037] Specifically, in step S3, the adjustment of at least one combustion environment parameter acting on the target moxa stick includes: Selectively adjust the air supply parameters of the air supply device and / or the mechanical pressure of the pressure application device; wherein the air supply parameters include at least one of wind force and wind direction.
[0038] Specifically, in this embodiment, the air supply parameters of the air supply device and the mechanical pressure of the pressure application device are the core adjustment objects. The air supply parameters (air force and direction) directly affect the oxygen supply and heat exchange efficiency in the combustion zone. Increasing the air force increases the oxygen contact, accelerating the combustion reaction; adjusting the air direction changes the contact position between oxygen and the combustion surface, affecting the local combustion speed; conversely, decreasing the air force or the air direction deviating from the combustion surface inhibits combustion. External pressure on the moxa stick changes its internal density and porosity. Increased pressure reduces the internal voids of the moxa stick, obstructing oxygen flow and slowing the combustion speed; decreased pressure increases the voids, allowing oxygen to penetrate more easily and accelerating the combustion speed.
[0039] These two adjustment parameters intervene in the combustion process from two dimensions: "external oxygen supply" and "internal combustion conditions," forming a complementary adjustment path that covers key environmental factors affecting combustion speed.
[0040] Furthermore, the combination of airflow parameters (external environment) and mechanical pressure (internal structure) can address different types of combustion deviations. For example, when the combustion surface area increases but the temperature distribution is uneven (the deviation is caused by uneven local oxygen distribution), adjusting the airflow direction can quickly correct local oxygen supply, which is more efficient than simply adjusting the pressure. When the moxa stick burns too slowly due to moisture (poor internal permeability), reducing the mechanical pressure can directly penetrate the internal pores, and combined with airflow adjustment, it can more precisely improve the combustion speed.
[0041] It should be noted that wind force, wind direction, and mechanical pressure are all quantifiable physical parameters (such as wind force which can be quantified by a wind speed sensor and pressure which can be monitored by a pressure sensor), which makes it easy to calculate and generate specific adjustment values based on deviations (such as increasing wind force from 2 m / s to 3 m / s), thus avoiding the subjectivity of manual adjustment.
[0042] Specifically, in step S3, generating control commands based on the deviation includes: S 31 The deviation is input to the proportional-integral-derivative controller to obtain the control quantity; S 32 : Generate control commands for adjusting the power of the air supply device and / or the pressure of the pressure application device based on the control quantity.
[0043] In this step, the PID controller calculates the control quantity and converts it into adjustment commands for the device, upgrading the adjustment of the burning speed deviation from empirical operation to quantifiable closed-loop control. The core of this technology is utilizing the multi-stage synergy of PID to achieve rapid response, error-free stability, and anti-interference effects, ultimately ensuring that the moxa stick's burning speed accurately tracks the target value, providing reliable technical support for the stability and safety of moxibustion treatment.
[0044] The proportional-integral-derivative controller involves the proportional element (P), integral element (I), and derivative element (D), which are explained in detail below: Proportional control (P): Directly outputs a control quantity based on the magnitude of the current deviation (the larger the deviation, the larger the control quantity), enabling rapid response to deviations. For example, if the current combustion speed far exceeds the target value (the deviation is positive and large), the proportional control will immediately output a large control quantity, driving the air supply device to reduce the airflow or the pressure device to increase the pressure, quickly suppressing combustion.
[0045] Integral stage (I): Accumulates historical deviations to eliminate long-standing steady-state errors. For example, if the combustion speed is consistently slightly lower than the target value (small deviation persists for a long time), the integral stage will gradually add control inputs, slowly increasing the adjustment intensity (such as continuously increasing the airflow) until the deviation returns to zero, avoiding the problem of being slightly off.
[0046] Differential component (D): Predicts trends based on the rate of change of deviation and applies reverse adjustment in advance to suppress overshoot. For example, if the combustion speed increases rapidly (the deviation increases quickly), the differential component will output a reverse control quantity to reduce the adjustment intensity in advance (such as reducing the wind speed increase in advance) to prevent the combustion speed from falling below the target value due to excessive adjustment.
[0047] Specifically, in step S3, when the deviation cannot be effectively corrected by adjusting the air supply parameters, the pressure application device is activated to apply controllable mechanical pressure to the unburned part of the moxa stick.
[0048] In this step, the air supply parameters (wind speed and direction) have a more direct and faster impact on the combustion speed (changes in oxygen supply can instantly alter the combustion reaction rate). Furthermore, this is a non-contact adjustment of the external environment of the moxa stick, which does not change the physical structure of the moxa stick itself, resulting in low intervention costs and high reversibility. Therefore, when deviations occur, adjusting the air supply parameters is prioritized, conforming to the control principle of "high efficiency and low intervention."
[0049] Mechanical pressure affects combustion by altering the density of the unburned portion of the moxa stick (e.g., compacted moxa sticks have lower porosity, making oxygen penetration more difficult and slowing combustion). However, its effect is somewhat delayed (pressure needs to be applied to the vicinity of the combustion surface to significantly influence the reaction), and it involves direct contact with the moxa stick itself. Therefore, it only activates when adjusting the air supply parameters fails to effectively correct the deviation. During continuous adjustment of the air supply parameters, a thermal imaging camera monitors the changes in combustion speed in real time (if the absolute value of the deviation does not decrease with adjustment time, or the rate of decrease is below a preset threshold), indicating that the air supply adjustment has failed. At this point, the system automatically switches to the pressure application device, applying controllable mechanical pressure to the unburned portion (the pressure magnitude is calculated by a PID controller based on the degree of deviation), thus intervening in the combustion speed from the perspective of the moxa stick's internal structure, forming a dual-regulation guarantee.
[0050] Specifically, before step S1, step S0 is also included: receiving the target burning speed setting value input by the user, or automatically matching the corresponding target burning speed based on the moxibustion treatment plan selected by the user.
[0051] For example, in this embodiment, the target burning speed is received directly by the user through an interactive interface (such as a button, touch screen, or voice input). This is particularly suitable for professional users (such as moxibustion therapists) to customize parameters based on experience or specific needs, ensuring the flexibility of the target value. The system has a built-in database of preset moxibustion treatment plans, each plan corresponding to a specific target burning speed (such as "gentle moxibustion" for a slower burning speed to provide continuous gentle stimulation, and "pecking moxibustion" for phased variable-speed burning). When the user selects a plan (such as "shoulder and neck conditioning plan"), the system automatically calls the pre-stored target burning speed, eliminating the need for manual calculation by the user and lowering the operational threshold.
[0052] Therefore, the user-defined setting function allows for adjustments to the target speed based on individual differences (such as patient constitution and tolerance). For example, a slower burning speed can be set for patients sensitive to heat (reducing heat output), while a faster speed can be set for patients with a cold constitution (enhancing heat penetration), making moxibustion treatment more tailored to individual needs. The automatic treatment plan matching function links the target burning speed to clinical experience (such as optimal parameters based on ancient records or modern research), preventing non-professional users from affecting the efficacy due to incorrect parameter settings. For example, the "warm needle moxibustion" plan automatically matches a medium burning speed to ensure stable heat transfer from the needles without burning the skin, improving the standardization and safety of the treatment.
[0053] Please see Figure 2 As shown, another embodiment of the present invention also provides a moxa stick burning speed control system for executing the moxa stick burning speed control method described above, the system comprising: The status monitoring module 100 is used to acquire real-time combustion status information of the target moxa stick's burning area. As a sensing end, the core function of the status monitoring module 100 is to collect real-time combustion status information (burning surface area, maximum temperature, temperature distribution characteristics, etc.). Through devices such as thermal imaging cameras, the physical process of moxa stick combustion is converted into quantifiable digital signals (such as temperature data and image pixel information), providing raw data support for subsequent processing and ensuring the timeliness and completeness of the data (e.g., acquiring 10 frames per second to capture dynamic changes in combustion).
[0054] The processing and control module 200, which is communicatively connected to the state monitoring module 100, is used to determine the current combustion speed and its deviation from the target combustion speed based on the combustion state information, and to generate control commands based on the deviation. As a decision-making end, the processing and control module 200 receives the output data from the state monitoring module 100, calculates the current combustion speed based on a pre-established combustion speed model (including parameters such as combustion surface area, maximum temperature, and temperature distribution characteristics), compares the current speed with the target combustion speed, determines the deviation, and generates control commands (such as adjusting the specific parameters of the air supply power and pressure value) through algorithms such as a PID controller, thus transforming the raw sensing data into an executable control strategy.
[0055] The execution module 300, communicatively connected to the processing and control module 200, is used to adjust at least one combustion environment parameter acting on the target moxa stick in response to the control command. As the execution end, the execution module 300 responds to the commands of the processing and control module 200 by changing the combustion environment parameters of the moxa stick through hardware such as an air supply device (adjusting wind force and direction) and a pressure application device (adjusting mechanical pressure), ensuring that the control command is translated into actual physical adjustment.
[0056] In this embodiment, the status monitoring module 100 sends the collected combustion status information to the processing and control module 200 in real time to avoid inaccurate decision-making due to data lag; the control commands generated by the processing and control module 200 are immediately transmitted to the execution module 300 to ensure the timeliness of the adjustment action (such as initiating wind speed adjustment within 1 second when the combustion speed suddenly increases); the adjustment results of the execution module 300 are fed back to the processing and control module 200 through the status monitoring module 100 to achieve dynamic correction (such as immediately initiating a second adjustment if the first adjustment fails to achieve the target).
[0057] Compared to traditional moxibustion, which relies on manual observation of the burning state and adjustments (such as fiddling with the moxa stick or adjusting the distance), resulting in issues like high subjectivity, slow response, and low precision, this system achieves full-process automation through modular division of labor. The status monitoring module 100 replaces human observation, the processing and control module 200 replaces human judgment, and the execution module 300 replaces manual operation, significantly reducing the need for human intervention and improving the consistency of control.
[0058] More specifically, in one embodiment of the present invention, the state monitoring module 100 is a thermal imaging camera. Specifically, the thermal imaging camera converts the infrared radiation of the combustion surface into an electrical signal, generating a heat map containing the temperature value of each pixel. The processor 210 can extract the combustion surface area (calculated by dividing the high-temperature region into pixels using a temperature threshold), the highest temperature (the maximum pixel temperature in the heat map), and temperature distribution characteristics (such as temperature standard deviation) from the heat map, thereby achieving quantitative perception of the combustion state. Its key logic is "non-contact, full-area temperature measurement," which avoids interference from contact sensors on the combustion process while covering the overall state of the combustion surface.
[0059] The processing and control module 200 includes a processor 210 and a memory 220. The memory 220 stores a computer program, and the processor 210 executes the computer program to implement the steps of the method described above. The execution module 300 is an air supply device used to change the wind force blowing towards the target moxa stick according to the control command. In this embodiment, the memory 220 pre-stores a combustion speed model, a PID control algorithm, and a target combustion speed (from user input or scheme matching). The processor 210 receives thermal image data from a thermal imaging camera by executing the computer program in the memory 220, analyzes the combustion surface area, maximum temperature, and temperature distribution characteristics, substitutes them into the combustion speed model to calculate the current combustion speed, compares it with the target value to obtain the deviation, and calls the PID algorithm to convert the deviation into a control quantity (such as the air supply power adjustment value) to generate control commands for the air supply device.
[0060] It is worth noting that, compared to traditional temperature sensors (such as thermocouples), thermal imaging cameras can simultaneously acquire the area of the burning surface, the highest temperature, and the temperature distribution, avoiding the limitations of a single temperature measurement point. For example, when a moxa stick burns too quickly in a localized area (the temperature rises sharply at a certain point but the area does not change significantly), thermal imaging can capture this detail, and the processor can generate targeted wind direction adjustment instructions based on this (such as reducing the wind force only in that area), while traditional sensors may miss this detection because they do not cover that point.
[0061] For more details, please refer to Figure 3 As shown, in one embodiment of the present invention, the execution module 300 further includes a pressure application device 310, which includes a stepper motor and a high-temperature resistant pressure plate connected to the stepper motor; the processing and control module 200 is further configured to generate a pressure control command when it is determined that the current combustion speed exceeds the target combustion speed and cannot be effectively corrected by adjusting the air supply device; the stepper motor responds to the pressure control command and drives the high-temperature resistant pressure plate to apply controllable mechanical pressure to the unburned part of the moxa stick.
[0062] In this embodiment, the stepper motor serves as the driving component, enabling precise displacement control via pulse signals (e.g., a fixed rotation angle per step, with quantifiable advance distance of the corresponding pressure plate), ensuring the controllability of mechanical pressure. The high-temperature resistant pressure plate is made of heat-resistant materials such as ceramics and metals, preventing deformation or damage due to high temperatures when in contact with the unburned parts of the moxa stick. Simultaneously, the planar contact ensures uniform pressure distribution, preventing the moxa stick from breaking due to excessive local compression.
[0063] This invention also provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps of the method described above.
[0064] The computer-readable storage medium serves as a carrier for the program. The computer-readable storage medium (such as hard disk, flash memory, optical disk, etc.) uses magnetic, optical or electrical signals to solidify the code of the moxa stick burning speed control method (including state monitoring data parsing, burning speed model calculation, PID control algorithm, actuator drive logic, etc.) into readable binary data, ensuring that the program can still be stably preserved after power failure.
[0065] When a processor (such as the CPU in the processing and control module) needs to execute a control method, it reads the computer program from the storage medium through the bus interface, loads it into memory, and executes the instructions one by one, ultimately realizing the entire process of obtaining the combustion status, calculating the deviation, and generating control instructions.
[0066] For example, the processor reads the "combustion rate model" code segment, calls the parameters such as the combustion surface area and the highest temperature collected by the thermal imaging camera, and substitutes them into the formula to calculate the current combustion rate. This process depends on the accurate reading of the program code in the storage medium.
[0067] Due to the standardization of storage media (such as universal USB flash memory and SD card formats), stored computer programs can be ported between different hardware devices (such as copying from laboratory debugging equipment to mass-produced moxibustion instruments). As long as the processor of the target device is compatible with the program's operating environment (such as operating system and instruction set), the same control logic can be reused without rewriting code for each device.
[0068] The computer program is embedded in the storage medium, avoiding the subjectivity and randomness of manual operation (such as the inconsistency of adjustment based on experience in traditional moxibustion), ensuring that the control logic executed each time (such as deviation calculation method and PID parameter call) is completely consistent, and realizing the standardization of moxa stick burning speed control.
[0069] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of this invention.
