Description

Technical Field

[0001] The present invention relates to the technical field of control systems, and particularly to a constant temperature heating control method for an internal medicine massage device integrating traditional Chinese and Western medicine. Background Art

[0002] With the wide application of the integrated traditional Chinese and Western medicine treatment method in internal medicine diseases, massage devices have gradually become an important tool for adjuvant treatment, especially showing significant curative effects in promoting blood circulation, relieving muscle tension and improving visceral functions. Among them, in order to meet the personalized needs of different patients and the precise regulation of temperature on meridians and acupoints emphasized by traditional Chinese medicine heat therapy, massage devices will enable a constant temperature regulation function to ensure curative effects and comfort.

[0003] Currently, for the constant temperature regulation of massage devices, the temperature is generally monitored in real time by a temperature sensor, and then a control algorithm is used to dynamically adjust the heating power according to the error between the set temperature and the current temperature. However, in actual application scenarios, during the process of heating the massage device to the set temperature, there are interferences such as thermal inertia and environmental temperature factors. Only based on the temperature detected by the temperature sensor for heating power control, the control system is prone to overreact to temperature deviations, resulting in temperature oscillation phenomena, or the heating power is too high when the device is heating up, leading to temperature overshoot. And when the temperature exceeds the set value, the heating stops quickly, causing the temperature to drop rapidly, and thus forming fluctuations up and down repeatedly. The regulation stability is poor, which will lead to a poor massage experience, increased energy consumption of the device, and even pose an overheating risk. Summary of the Invention

[0055] The following specifically describes the specific solution of a constant temperature heating control method for an internal medicine massage device integrating traditional Chinese and Western medicine provided by the present invention with reference to the accompanying drawings.

[0056] Please refer to Figure 1 , which shows a flowchart of a constant temperature heating control method for an internal medicine massage device integrating traditional Chinese and Western medicine provided by an embodiment of the present invention. The constant temperature heating control method for the internal medicine massage device integrating traditional Chinese and Western medicine can at least include steps S100 - S400:

[0057] S100. Obtain the historical device data of the internal medicine massage device integrating traditional Chinese and Western medicine, and determine the temperature influence degree of the environmental temperature on the internal medicine massage device integrating traditional Chinese and Western medicine according to the historical device data.

[0058] Optionally, the historical equipment data includes historical heating power, historical set temperature, temperature-time curve, historical ambient temperature at several moments (e.g., every second), and historical equipment temperature at several moments. It should be noted that, during the operation of the Western medicine combined internal medicine massage equipment, the historical ambient temperature, historical equipment temperature, historical heating power, equipment operation status, etc. can be obtained through electronic components such as temperature sensors, power monitoring modules, and operation status detectors. The temperature sensor is calibrated in advance by a known temperature source to ensure the accuracy of data acquisition; when different ambient temperature conditions (such as low temperature, medium temperature, and high temperature) are selected for experiments, the historical ambient temperature is recorded to ensure the stability of the experimental environment. These conditions simulate various actual working environments that the equipment may face; the temperature-time curve is drawn based on the historical equipment temperature and time at different moments; the equipment operation status includes testing the heat demand of the massage head in different operation modes, such as slow movement, high-frequency vibration, etc., and power consumption and temperature response under various contact area changes of the equipment (such as full contact or partial contact, etc.).

[0059] In some embodiments, when the temperature of the Chinese and Western medicine combined internal medicine massage device is stable, the heating function can be turned off, and the temperature change curve of the device during the natural cooling process can be recorded. This process is repeated under different ambient temperature conditions to estimate the heat loss of the device per unit time. In addition, all acquired historical device data can be pre-processed to remove abnormal values ​​and noise data to ensure that the recorded historical device data is reliable, and then the data under different experimental conditions (such as ambient temperature, operating status, etc.) are normalized for unified analysis; then the temperature rise, heat loss and operating status data are interpolated and supplemented in time series to avoid information loss caused by sampling intervals, and finally the continuity and readability of the curve data are optimized through smoothing, providing a high-quality data basis for subsequent analysis.

[0061] Optionally, when the integrated Chinese and Western medicine internal medicine massage device is currently in use, the current device temperature, current ambient temperature, current set temperature and the current temperature difference between the current set temperature and the current device temperature of the integrated Chinese and Western medicine internal medicine massage device can be obtained in real time through electronic components such as temperature sensors, power monitoring modules and operation status detectors.

[0062] S300, adjusting the initial heating power according to the current set temperature, the current ambient temperature and the temperature influence to obtain the target heating power.

[0063] S400. Control the integrated traditional Chinese and Western medicine internal medicine massage device to perform constant temperature heating according to the target heating power.

[0064] The technical solution of the embodiment of the present application obtains the historical device data of the integrated traditional Chinese and Western medicine internal medicine massage device, determines the temperature influence degree of the environmental temperature on the integrated traditional Chinese and Western medicine internal medicine massage device according to the historical device data, and determines the current device temperature, current environmental temperature, current set temperature of the integrated traditional Chinese and Western medicine internal medicine massage device in real time, and the current temperature difference between the current set temperature and the current device temperature. According to the current temperature difference and the temperature-time curve, the initial heating power is determined. According to the current set temperature, current environmental temperature and temperature influence degree, the initial heating power is adjusted to obtain the target heating power. According to the target heating power, the integrated traditional Chinese and Western medicine internal medicine massage device is controlled to perform constant temperature heating, considering the influence degree of the environmental temperature factor on the temperature of the massage device, making the target heating power more accurate. Controlling the constant temperature heating through the target heating power is beneficial to improving the regulation stability, massage experience and reducing energy consumption.

[0065] It should be noted that the principle of the integrated traditional Chinese and Western medicine internal medicine massage device is to achieve treatment through constant temperature control, promote blood circulation, relieve muscle tension and reduce pain through a stable temperature. Precise constant temperature control enables the massage device to provide a continuous and comfortable heat therapy effect during the treatment process. Usually, it takes a certain amount of time for the device to heat up to the set temperature, and the heat transfer efficiency directly determines the response time of the heating process. By analyzing the time required for the device to heat up to the set temperature, it provides a reference for subsequent temperature regulation.

[0066] In one implementation, the temperature-time curve includes the curves of the device temperature changing with time at different heating powers, and the magnitudes of different heating powers are determined based on the actual situation of the integrated traditional Chinese and Western medicine internal medicine massage device; determining the temperature influence degree of the environmental temperature on the integrated traditional Chinese and Western medicine internal medicine massage device according to the historical device data in step S100 includes steps S101 - S105:

[0067] S101. Determine the historical temperature difference between the historical set temperature and the historical device temperature at each moment, and determine the target curve of the device temperature changing with time corresponding to the historical heating power.

[0068] For example, if the set temperature is 30 °C, then during the entire period of this control, the historical set temperature at each moment is 30 °C. However, since the device temperature will change during the temperature rising process, the historical device temperature at each moment may be different. Therefore, determine the historical temperature difference between the historical set temperature and the historical device temperature at each moment. At the same time, according to the measured historical heating power and the historical device temperature at different moments, construct the target curve of the device temperature changing with time corresponding to the historical heating power. Such as Figure 2As shown, target curves of the device temperature varying with time corresponding to four different historical heating powers (Power), namely 50W, 100W, 150W, and 200W, are exemplarily given. When selecting the historical heating power, it can be selected based on the historical heating powers supported by the integrated traditional Chinese and Western medicine internal medicine massage device itself. The quantity and magnitude of the historical heating powers are not specifically limited.

[0069] S102. According to each historical temperature difference, respectively determine the corresponding historical heating-up duration from the target curve.

[0070] Optionally, for example, when the historical heating power is 150W, assuming the historical device temperature is 40°C and the historical set temperature is 55°C, that is, the historical temperature difference is 15°C, from Figure 2 it can be correspondingly determined that the historical heating-up duration is 100s - 50s = 50s; based on this principle, the corresponding historical heating-up duration for each can be respectively determined from the target curve.

[0071] S103. According to the preset device heat capacity, historical temperature difference, each corresponding historical heating-up duration, and historical heating power, respectively calculate the historical heat transfer efficiency corresponding to each moment.

[0072] First, respectively determine the first product of the preset device heat capacity and each historical temperature difference , and respectively determine the first ratio of each first product to the corresponding each historical heating-up duration . .

[0073] Second, respectively determine the second ratio of the historical heating power to each first ratio, and obtain the historical heat transfer efficiency corresponding to each moment :

[0074]

[0075] It should be noted that the change in the ambient temperature will affect the heat accumulation or dissipation of the massage device, resulting in fluctuations in the actual required heating power of the device. If the ambient temperature is low, the device will dissipate heat faster, so the heating power needs to be increased to compensate for the heat loss; if the ambient temperature is high, the heating power can be appropriately reduced. At the same time, the stability of the device under different environmental conditions also needs to be considered to ensure that the device can work normally within a relatively wide range of ambient temperatures; among them, the heat loss is mainly driven by the temperature difference between the massage device and the environment. When the ambient temperature decreases, the temperature difference increases, and the heat loss increases significantly, and the device needs to consume more power to maintain the set temperature; on the contrary, at a higher ambient temperature, the heat loss decreases and the heating efficiency increases.

[0076] S104. Determine the heat loss caused by the difference between the historical ambient temperature and the historical equipment temperature at each moment based on the historical ambient temperature at several moments, the historical equipment temperature at several moments, the preset heat transfer coefficient, and the equipment surface area of the integrated traditional Chinese and Western medicine internal medicine massage equipment.

[0077] First, based on the historical ambient temperature at several moments and the historical equipment temperature at several moments , respectively determine the first absolute value of the difference between the corresponding historical equipment temperature and the historical ambient temperature at each moment .

[0078] Second, respectively determine the second product of the corresponding first absolute value at each moment , the preset heat transfer coefficient and the equipment surface area to determine the heat loss caused by the difference between the historical ambient temperature and the historical equipment temperature at each moment :

[0079]

[0080] S105. Determine the temperature influence degree of the ambient temperature on the integrated traditional Chinese and Western medicine internal medicine massage equipment according to the corresponding historical heat transfer efficiency at each moment and the heat loss at each moment.

[0081] First, respectively determine the second absolute value of the difference between the corresponding historical heat transfer efficiency at each moment and the ideal heat transfer efficiency to obtain the loss of the heat transfer efficiency (the larger the value, the greater the degree of influence on the heat transfer efficiency); according to the loss of the heat transfer efficiency and the heat loss and , respectively determine the first change rate of the heat loss at each moment ( ) and the second change rate of the loss of the heat transfer efficiency , and determine the third absolute value of the difference between the first change rate and the second change rate . It should be noted that the calculation of the change rate can be achieved by existing means, for example, by using the heat loss at adjacent moments , respectively calculated, which will not be elaborated here.

[0082] Second, according to all the third absolute values and the number of the third absolute values (which can also be called the number of moments), calculate the average value: .

[0083] Then, according to the average value and the natural exponential function​ , determine the temperature influence degree of the integrated traditional Chinese and Western medicine internal medicine massage device by the ambient temperature :

[0084]

[0085] Among them, represents the variation correspondence relationship between the heat loss and the loss of the heat transfer efficiency at the corresponding moment in all historical device data. The smaller this formula is, the more consistent the variation is, indicating that the influence of the environment on the device temperature change is greater.

[0086] In one implementation, in step S200, according to the current temperature difference and the temperature-time curve, determine the initial heating power, including steps S201 - S203:

[0087] S201. According to the current temperature difference, respectively determine the corresponding current heating-up duration from the curves of the device temperature changing with time at different heating powers.

[0088] Similarly, based on Figure 2 and the principle of step S100, according to the current temperature difference, respectively determine the corresponding current heating-up duration from the curves of the device temperature changing with time at different heating powers.

[0089] S202. According to the preset device heat capacity, the current temperature difference, different current heating-up durations, and different heating powers corresponding to different current heating-up durations, respectively calculate the corresponding current heat transfer efficiency.

[0090] Similarly, as Figure 2 shown, based on the above formula , substitute the current temperature difference into , substitute different current heating-up durations into , substitute different heating powers into , at this time, the corresponding can be calculated respectively, and the at this time is used as the corresponding current heat transfer efficiency.

[0091] S203. Take the heating power corresponding to the calculated maximum current heat transfer efficiency as the initial heating power.

[0092] Finally, determine the maximum current heat transfer efficiency from the above various current heat transfer efficiencies , and take the heating power corresponding to the calculated maximum current heat transfer efficiency as the initial heating power. For example, if the maximum current heat transfer efficiency is 95%, and it is calculated using a heating power of 100w, then 100w is used as the initial heating power at this time .

[0093] In one embodiment, step S300 includes steps S301 - S303:

[0094] S301. Determine the fourth absolute value of the difference between the current ambient temperature and the current set temperature, and determine the third product of the fourth absolute value and the temperature influence degree. Obtain the compensated heating power based on the sum of the third product and the initial heating power.

[0095] Optionally, determine the current ambient temperature and the current set temperature of the fourth absolute value of the difference , and determine the fourth absolute value and the temperature influence degree of the third product , based on the third product and the initial heating power of the sum, obtain the compensated heating power compensated for environmental interference (such as temperature) :

[0096]

[0097] It should be noted that the operating state of the integrated traditional Chinese and Western medicine internal medicine massage device, such as the movement of the massage head or the area of contact with the human body, will affect its heat demand. For example, when the contact area between the massage head and the human body is larger, the heat demand increases; when the speed of the massage head is faster, the heat demand also increases. Therefore, adjust the heating power according to the operating state of the device to match the real - time heat demand. Specifically, by analyzing the operating state of the integrated traditional Chinese and Western medicine internal medicine massage device, the movement speed of the massage head and the area of contact with the human body can be combined to dynamically evaluate the heat demand of the device. When the massage head is moving at a high speed, due to the heat dissipation effects of friction and air flow, the heat loss increases, and a higher heating power is required to maintain the set temperature; when the movement speed is lower, the heat loss decreases, and the heating power can be correspondingly reduced. At the same time, the area of contact between the massage head and the human body directly affects the conduction and dissipation of heat. A larger contact area will cause more heat to be transferred to the human body, increasing the heat demand, while a smaller contact area has the opposite effect. By real - time monitoring the movement parameters (speed and area) of the massage head, the heat demand can be obtained.

[0098] S302. Determine the current heat demand of the integrated traditional Chinese and Western medicine internal medicine massage device in real - time.

[0099] First, obtain in real - time the change ratio of the contact area between the massage head of the integrated traditional Chinese and Western medicine internal medicine massage device and the massage object , the adjustment power coefficient based on the contact area , the movement speed of the massage head and the adjustment power coefficient based on the movement speed .

[0100] Secondly, determine the change ratio of the contact area of the object to be massaged and the adjustment power coefficient based on the contact area for the fourth product , and determine the moving speed of the massage head and the adjustment power coefficient based on the moving speed for the fifth product . Among them, the adjustment power coefficient based on the contact area and the adjustment power coefficient based on the moving speed both refer to a weight coefficient, which can be reasonably set as needed. For example, the adjustment power coefficient based on the contact area can be the Pearson correlation coefficient between the change in contact area and the sequence data of temperature changes under the same conditions, that is, obtain in advance different contact areas and temperature values under different contact areas under the same conditions (other conditions are the same except for the contact area), and arrange the different contact areas in ascending order to form a contact area sequence, and arrange the temperature values under different contact areas in the arrangement order of the contact area to form a first temperature change sequence, calculate the Pearson correlation coefficient between the contact area sequence and the first temperature change sequence, and use this Pearson correlation coefficient as the adjustment power coefficient based on the contact area ; similarly, the adjustment power coefficient based on the moving speed can be the Pearson correlation coefficient between the change in moving speed and the sequence data of temperature changes under the same conditions, that is, obtain in advance different moving speeds and temperature values under different moving speeds under the same conditions (other conditions are the same except for the moving speed), and arrange the different moving speeds in ascending order to form a moving speed sequence, and arrange the temperature values under different moving speeds in the arrangement order of the moving speed to form a second temperature change sequence, calculate the Pearson correlation coefficient between the moving speed sequence and the second temperature change sequence, and use this Pearson correlation coefficient as the adjustment power coefficient based on the moving speed .

[0101] Then, according to the first sum value of the fourth product and the fifth product, obtain the current heat demand (required for the current operating state) of the integrated traditional Chinese and Western medicine internal medicine massage device :

[0102]

[0103] S303. Obtain the target heating power according to the compensation heating power and the current heat demand

[0104] Optionally, assume that the preset value is 1, determine the second sum value of the preset value 1 and the current heat demand , and then according to the second sum value , The sixth product with the compensated heating power to obtain the target heating power :

[0105]

[0106] wherein, represents adjusting the heating power according to the heat required for the operating state of the massage device that combines different patient needs. In the embodiments of the present application, the heating power is adjusted by the real-time current heat demand due to the operating state of the massage device, ensuring that the device can meet the heat demand and avoid overheating or discomfort in different working states, thereby improving the temperature control accuracy and treatment effect of the device.

[0107] In one embodiment, step S400 includes steps S401 - S404:

[0108] S401. Obtain the predicted heating-up duration according to the target heating power and the curve of the device temperature varying with time at different heating powers.

[0109] Optionally, according to the target heating power, the curve of the device temperature varying with time corresponding to the target heating power can be determined, and then based on the temperature difference between the current device temperature and the current set temperature, the predicted heating-up duration can be determined in the curve. .

[0110] S402. Determine the temperature trend value according to the preset device heat capacity, the predicted heating-up duration, the target heating power, and the current device temperature.

[0111] Specifically, the formula is:

[0112]

[0113] wherein, represents the temperature trend value, represents the current device temperature, represents the preset device heat capacity; represents the increment of temperature change per unit time, representing the temperature change increment caused by the heat input due to the target heating power after time.

[0114] S403. Determine the target temperature error range according to the temperature trend value and the current set temperature.

[0115] Specifically, the formula is:

[0116]

[0117] wherein, Represents the target temperature error range, which is used to evaluate whether heating needs to be paused;

[0118] In some embodiments, on the basis above, the target temperature error range can also be determined based on the application scenario and treatment requirements of internal medicine massage. For example:

[0119] 1. Considering user comfort: The temperature error range should not be too large to avoid affecting the user experience. For devices in contact with the human body, it is recommended that the target temperature error range be ±0.5°C to ±1.0°C to ensure accurate temperature control and avoid being too cold or too hot;

[0120] 2. Equipment thermal inertia: Based on the heating and cooling inertia of the massage device, the target temperature error range is slightly larger, at ±1.0°C to ±2.0°C, to avoid system oscillations caused by frequent heating switches;

[0121] 3. Precision requirements for treatment goals: High-precision treatment (such as acupuncture heat therapy or thermosensitive drug release): The target temperature error range is taken as ±0.2°C to ±0.5°C; General heat therapy (such as relieving muscle soreness): The target temperature error range is taken as ±1.0°C to ±2.0°C.

[0122] S404. Control the integrated traditional Chinese and Western medicine internal medicine massage device to heat at the target heating power. When the current device temperature is outside the target temperature error range, continue heating. When the current device temperature is within the target temperature error range, stop heating.

[0123] Optionally, in actual applications, control the integrated traditional Chinese and Western medicine internal medicine massage device to heat at the target heating power. When the current device temperature is outside the target temperature error range, continue heating at this time. And if the current device temperature is within the target temperature error range, stop heating at this time, and use the remaining heat to gradually approach the current set temperature to avoid overheating or temperature oscillation caused by thermal inertia.

[0124] In addition, once the current set temperature is reached, enter the constant temperature mode, continuously monitor the current device temperature, and fine-tune the heating power output according to the actual situation to ensure that the device temperature is maintained within the target temperature error range; Since the constant temperature error is controlled within a very small range, it ensures the adaptability, energy efficiency, and comfortable experience of the patient. At the same time, during the operation of the constant temperature mode, the device continuously obtains feedback data on the ambient temperature and operating status. When the external ambient temperature suddenly changes or the massage mode changes, the device will adjust immediately and re-determine the target heating power to adapt to the new heat demand, ensuring that the device can maintain stable performance under different conditions.

[0125] It should be noted that every moment or a preset number of moments later, S200 will be returned to determine in real time the current device temperature, current ambient temperature, current set temperature of the integrated traditional Chinese and Western medicine internal medicine massage device, and the current temperature difference between the current set temperature and the current device temperature, and continuously re-determine the target heating power, temperature trend value, and target temperature error range to judge whether the current device temperature is within or outside the target temperature error range, so as to ensure the constant temperature control effect, avoid serious temperature oscillation phenomena, have high regulation stability, and good massage experience.

[0126] The method of the embodiment of the present application analyzes the time for the device to heat up to the set temperature through historical device data, calculates the historical heat transfer efficiency, which helps to clarify the heating response time, optimize the heating strategy, reduce energy consumption, and provide accurate parameters for temperature trend prediction; evaluates the influence of different indoor ambient temperatures on heat loss, establishes a relationship model between the ambient temperature and the heating power demand, determines the temperature influence degree, can dynamically compensate for heat fluctuations, ensure the stable operation of the device under various environmental conditions, and improve the user experience; monitors the real-time operation state of the device and adapts the heating power, can achieve personalized heat adjustment, improve safety and extend the service life of the device; combines environmental factors with heat transfer efficiency to predict the temperature change trend, effectively prevents over-regulation and oscillation caused by thermal inertia, improves the temperature control accuracy and reduces energy consumption, enhances the stability and accuracy of the constant temperature control of the internal medicine massage device, and at the same time improves the device performance and user comfort.
