Description

Technical Field

[0002] With the widespread application of combined Chinese and Western medicine treatment methods in internal medicine, massage equipment has gradually become an important tool for auxiliary treatment, especially in promoting blood circulation, relieving muscle tension and improving visceral function. In order to meet the personalized needs of different patients and the emphasis of TCM heat therapy on the precise regulation of temperature on meridians and acupoints, massage equipment will enable constant temperature regulation to ensure efficacy and comfort.

[0003] At present, the constant temperature regulation of massage equipment generally monitors the temperature in real time through a temperature sensor, and then uses a control algorithm to dynamically adjust the heating power according to the error between the set temperature and the current temperature. However, in actual application scenarios, when the massage equipment is heated to the set temperature, there will be interference from thermal inertia, ambient temperature factors, etc. If the heating power is controlled only based on the temperature detected by the temperature sensor, the control system is prone to overreact to temperature deviations, resulting in temperature oscillation, or the heating power is too high when the equipment is heated, resulting in temperature overshoot, and the heating is quickly stopped after the temperature exceeds the set value, causing the temperature to drop rapidly, and repeated ups and downs form, and the control stability is poor, which will lead to a poor massage experience, increased equipment energy consumption, and even overheating risks.

DETAILED DESCRIPTION

[0017] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the constant temperature heating control method of a Chinese and Western medicine combined internal medicine massage device proposed by the present invention, its specific implementation method, structure, features and effects as follows in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0018] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0019] It should be noted that the term “exemplary” in the embodiments of the present application refers to examples listed for the convenience of explanation, and other embodiments are not limited to the examples listed.

[0020] The specific scheme of the constant temperature heating control method of the internal medicine massage equipment combining traditional Chinese and western medicine provided by the present invention is described in detail below with reference to the accompanying drawings.

[0021] See also Figure 1 , which shows a flow chart of a constant temperature heating control method of a Chinese and Western medicine combined internal medicine massage device provided by an embodiment of the present invention. The constant temperature heating control method of the Chinese and Western medicine combined internal medicine massage device may at least include steps S100-S400: S100, obtaining historical equipment data of the integrated Chinese and Western medicine internal medicine massage equipment, and determining the influence of the ambient temperature on the temperature of the integrated Chinese and Western medicine internal medicine massage equipment based on the historical equipment data.

[0022] 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.).

[0023] 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.

[0025] 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.

[0026] 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.

[0027] S400, according to the target heating power, controlling the Chinese and Western medicine combined internal medicine massage equipment to perform constant temperature heating.

[0028] The technical solution of the embodiment of the present application obtains historical equipment data of the integrated Chinese and Western medicine internal medicine massage device, and determines the influence of the ambient temperature on the temperature of the integrated Chinese and Western medicine internal medicine massage device based on the historical equipment data, and determines in real time the current equipment temperature, the current ambient temperature, the current set temperature and the current temperature difference between the current set temperature and the current equipment temperature of the integrated Chinese and Western medicine internal medicine massage device, and determines the initial heating power according to the current temperature difference and the temperature-time curve, and adjusts the initial heating power according to the current set temperature, the current ambient temperature and the temperature influence to obtain the target heating power, and controls the integrated Chinese and Western medicine internal medicine massage device to perform constant temperature heating according to the target heating power, taking into account the influence of the ambient temperature factor on the temperature of the massage device, so that the target heating power is more accurate, and the constant temperature heating is controlled by the target heating power, which is beneficial to improving the regulation stability, massage experience and reducing energy consumption.

[0029] It should be noted that the principle of the integrated Chinese and Western medicine internal medicine massage equipment is to achieve treatment through constant temperature control, promote blood circulation, relieve muscle tension and reduce pain through stable temperature, and precise constant temperature control enables the massage equipment to provide continuous and comfortable thermal therapy effects during the treatment process. It usually takes a certain amount of time for the equipment 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 equipment to heat up to the set temperature, a reference can be provided for subsequent temperature control.

[0030] In one embodiment, the temperature-time curve includes a curve of device temperature changes over time at different heating powers, and the magnitude of the different heating powers is determined based on the actual situation of the Chinese and Western medicine combined internal medicine massage device; in step S100, the influence of the ambient temperature on the temperature of the Chinese and Western medicine combined internal medicine massage device is determined according to historical device data, including steps S101-S105: S101, determining the historical temperature difference between the historical set temperature and the historical device temperature at each moment, and determining a target curve of the device temperature corresponding to the historical heating power changing with time.

[0031] For example, if the temperature is set to 30°C, then during the entire time period of this control, the historical set temperature at each moment is 30°C. Since the device temperature changes during the heating process, the historical device temperature at each moment may be different. Therefore, the historical temperature difference between the historical set temperature and the historical device temperature at each moment is determined. At the same time, based on the measured historical heating power and the historical device temperature at different moments, a target curve of the device temperature changing over time corresponding to the historical heating power is constructed. Figure 2 As shown, target curves of device temperature changing with time corresponding to four different historical heating powers (Power) of 50W, 100W, 150W and 200W are given as examples. When selecting the historical heating power, it can be selected based on the historical heating power supported by the combined Chinese and Western medicine internal massage device itself. The number and size of the historical heating power are not specifically limited.

[0032] S102. According to each historical temperature difference, determine the corresponding historical temperature rise time from the target curve.

[0033] Optionally, for example, when the historical heating power is 150W, assuming that the historical device temperature is 40°C and the historical set temperature is 55°C, that is, the historical temperature difference is 15°C, Figure 2 The historical temperature rise time can be determined to be 100s-50s=50s; based on this principle, each corresponding historical temperature rise time can be determined from the target curve.

[0034] S103, calculating the historical heat transfer efficiency corresponding to each moment according to the preset equipment heat capacity, the historical temperature difference, each corresponding historical heating time and the historical heating power.

[0035] First, determine the preset equipment heat capacity The temperature difference with each historical The first product of each first product and the corresponding historical temperature rise time are determined respectively. The first ratio .

[0036] Secondly, determine the historical heating power The historical heat transfer efficiency corresponding to each moment is obtained by comparing the second ratio of each first ratio. : It should be noted that changes in ambient temperature will affect the heat accumulation or dissipation of massage equipment, causing fluctuations in the actual heating power required by the equipment. If the ambient temperature is low, the equipment 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 equipment under different environmental conditions must also be considered to ensure that the equipment can work normally within a wide range of ambient temperatures; among them, heat loss is mainly driven by the temperature difference between the massage equipment and the environment. When the ambient temperature decreases, the temperature difference increases, the heat loss increases significantly, and the equipment needs to consume more power to maintain the set temperature; on the contrary, at higher ambient temperatures, heat loss decreases and heating efficiency increases.

[0037] 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 Chinese and Western medicine internal medicine massage equipment.

[0038] First, based on the historical ambient temperature at several moments And the historical device temperature at several moments , respectively determine the first absolute value of the difference between the historical device temperature and the historical ambient temperature corresponding to each moment .

[0039] Secondly, determine the first absolute value corresponding to each moment , preset heat transfer coefficient Surface area of ​​equipment The second product of the historical ambient temperature and the historical equipment temperature at each moment determines the heat loss caused by the difference : S105. Determine the influence of the ambient temperature on the temperature of the integrated Chinese and Western medicine internal medicine massage device based on the historical heat transfer efficiency corresponding to each moment and the heat loss at each moment.

[0040] First, determine the historical heat transfer efficiency corresponding to each moment With ideal heat transfer efficiency The second absolute value of the difference , and the loss of heat transfer efficiency is obtained (The larger the value, the greater the degree to which the heat transfer efficiency is affected); according to the loss of heat transfer efficiency and heat loss , respectively determine each moment ( ) The first rate of change of heat loss and the second rate of change of the loss of heat transfer efficiency , and determine the third absolute value of the difference between the first rate of change and the second rate of change It should be noted that the calculation of the rate of change can be achieved by existing means, such as using the heat loss at adjacent moments. , They are calculated separately and will not be described in detail.

[0041] Secondly, according to all third absolute values ​​and the number of third absolute values (also called the number of moments), calculate the average: .

[0042] Then, according to the mean and the natural exponential function , determine the influence of ambient temperature on the temperature of the integrated Chinese and Western medicine massage equipment : in, It represents the changing correspondence between the heat loss in all historical equipment data and the loss of heat transfer efficiency at the corresponding moment. The smaller the formula is, the more consistent the change is, which means that the environment has a greater impact on the temperature change of the equipment.

[0043] In one embodiment, the initial heating power is determined according to the current temperature difference and the temperature-time curve in step S200, including steps S201-S203: S201. According to the current temperature difference, determine the corresponding current heating time from the curves of the temperature change of the equipment with different heating powers over time.

[0044] Similarly, based on Figure 2 As well as the principle of step S100, the corresponding current heating time can be determined from the curves of the temperature change of devices with different heating powers over time according to the current temperature difference.

[0045] S202. Calculate the corresponding current heat transfer efficiency according to the preset equipment heat capacity, the current temperature difference, different current heating time periods, and different heating powers corresponding to different current heating time periods.

[0046] Similarly, if Figure 2 As shown, based on the above formula , the current temperature difference is substituted into , different current heating durations are substituted , different heating powers are substituted , then we can calculate , at this time as the corresponding current heat transfer efficiency.

[0047] S203, taking the heating power corresponding to the maximum current heat transfer efficiency obtained by calculation as the initial heating power.

[0048] Finally, determine the maximum current heat transfer efficiency from the above current heat transfer efficiencies , and the maximum current heat transfer efficiency will be calculated The corresponding heating power is used as the initial heating power. For example, if the maximum current heat transfer efficiency is 95%, the corresponding heating power is calculated using 100w. In this case, 100w is used as the initial heating power. .

[0049] In one implementation, step S300 includes steps S301-S303: S301, determining a fourth absolute value of the difference between the current ambient temperature and the current set temperature, and determining a third product of the fourth absolute value and the temperature influence, and obtaining a compensation heating power according to the sum of the third product and the initial heating power.

[0050] Optionally, determine the current ambient temperature With the current set temperature The fourth absolute value of the difference , and determine the fourth absolute value and temperature influence The third product of , according to the third product and the initial heating power The sum of the compensation heating power after compensation for environmental interference (such as temperature) is obtained. : It should be noted that the operating state of the integrated Chinese and Western medicine internal medicine massage equipment, 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 large, the heat demand increases; and when the massage head moves faster, the heat demand will also increase. Therefore, the heating power is adjusted according to the operating state of the equipment to match the real-time heat demand. Specifically, by analyzing the operating state of the integrated Chinese and Western medicine internal medicine massage equipment, the heat demand of the equipment can be dynamically evaluated in combination with the movement speed of the massage head and the area of ​​contact with the human body. When the massage head moves at high speed, due to the heat dissipation effect 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 low, the heat loss decreases, and the heating power can be reduced accordingly. 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 will be the opposite. The heat demand can be obtained by real-time monitoring of the movement parameters (speed and area) of the massage head.

[0051] S302, determining the current heat demand of the integrated Chinese and Western medicine internal medicine massage device in real time.

[0052] First, obtain the change ratio of the contact area between the massage head of the integrated Chinese and Western medicine internal massage device and the massaged object in real time , Adjusted power coefficient based on contact area , Movement speed of massage head and an adjusted power factor based on the speed of movement .

[0053] Secondly, determine the change ratio of the contact area of ​​the massaged object With adjusted power coefficient based on contact area The fourth product of , and determine the movement speed of the massage head and an adjusted power factor based on movement speed The fifth product of Among them, the adjustment power coefficient based on the contact area and adjust the power factor based on the speed of movement Each refers to a weight coefficient, which can be set reasonably as needed. For example, the adjustment power coefficient based on the contact area The Pearson correlation coefficient of the contact area change and temperature change sequence data under the same conditions can be obtained in advance, that is, different contact areas and temperature values ​​under the same conditions (other conditions except the contact area are the same), and the different contact areas are arranged in order from small to large to form a contact area sequence, and the temperature values ​​under different contact areas are arranged in the order of arrangement of the contact areas to form a first temperature change sequence, and the Pearson correlation coefficient of the contact area sequence and the first temperature change sequence is calculated, and the Pearson correlation coefficient is used as the adjustment power coefficient based on the contact area. ; Similarly, the power factor adjusted based on the speed of movement The Pearson correlation coefficient of the sequence data of the movement speed change and the temperature change under the same conditions can be obtained in advance, that is, different movement speeds and temperature values ​​under the same conditions (other conditions except the movement speed are the same) are obtained in advance, and the different movement speeds are arranged in order from small to large to form a movement speed sequence, and the temperature values ​​under different movement speeds are arranged in the order of the movement speed to form a second temperature change sequence, and the Pearson correlation coefficient of the movement speed sequence and the second temperature change sequence is calculated, and the Pearson correlation coefficient is used as the adjustment power coefficient based on the movement speed. .

[0054] Then, according to the first sum of the fourth product and the fifth product, the current heat demand of the Chinese and Western medicine combined internal medicine massage device (required in the current operating state) is obtained. : S303: Obtain target heating power according to the compensation heating power and the current heat demand.

[0055] Optionally, assuming that the preset value is 1, determine the preset value 1 and the current heat demand The second sum of , and then according to the second sum With compensation heating power The sixth product of : in, Indicates that the heating power is adjusted according to the heat required for the operation state of the massage device in combination with the needs of different patients. In the embodiment of the present application, the heating power is adjusted by the real-time current heat demand required by the operation state of the massage device to ensure 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.

[0056] In one implementation, step S400 includes steps S401-S404: S401. Obtain a predicted heating time according to the target heating power and the curve of the temperature change of the equipment with different heating powers over time.

[0057] Optionally, according to the target heating power, a curve of the device temperature change over 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 time can be determined in the curve. .

[0058] S402: Determine a temperature trend value according to a preset device heat capacity, a predicted heating time, a target heating power, and a current device temperature.

[0059] Specifically, the formula is: in, Indicates the temperature trend value, Indicates the current device temperature. Indicates the preset equipment thermal capacity; Indicates the increment of temperature change per unit time, representing the The incremental temperature change caused by the heat input brought by the target heating power after a certain time.

[0060] S403: Determine a target temperature error range according to the temperature trend value and the current set temperature.

[0061] Specifically, the formula is: in, Indicates the target temperature error range, which is used to evaluate whether heating needs to be suspended; In some embodiments, based on the above, the target temperature error range can also be determined based on the application scenario and treatment requirements of internal medicine massage, for example: 1. Consider user comfort: The temperature error range should not be too large to avoid affecting the user experience. For human contact equipment, the recommended target temperature error range is ±0.5°C to ±1.0°C to ensure accurate temperature control and avoid overcooling or overheating; 2. Equipment thermal inertia: Based on the heating and cooling inertia of the massage equipment, the target temperature error range is slightly larger (±1.0°C to ±2.0°C) to avoid frequent heating switches causing system oscillation; 3. Accuracy requirements for treatment targets: High-precision treatment (such as acupuncture heat therapy or thermosensitive drug release): the target temperature error range is ±0.2°C to ±0.5°C; general heat therapy (such as relieving muscle soreness): the target temperature error range is ±1.0°C to ±2.0°C.

[0062] S404, controlling the integrated Chinese and Western medicine internal medicine massage device to heat at a target heating power, and when the current device temperature is outside the target temperature error range, continuing heating, and when the current device temperature is within the target temperature error range, stopping heating.

[0063] Optionally, in actual applications, the combined Chinese and Western medicine internal medicine massage equipment is controlled to heat at a target heating power. When the current equipment temperature is outside the target temperature error range, heating is continued. If the current equipment temperature is within the target temperature error range, heating is stopped and residual heat is used to gradually approach the current set temperature to avoid excessive heating or temperature oscillation due to thermal inertia.

[0064] In addition, once the current set temperature is reached, the device enters the constant temperature mode, continuously monitors the current device temperature, and fine-tunes 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, the adaptability, energy efficiency and patient comfort of the device are ensured. 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.
