Description

Technical Field

[0001] The present invention relates to the technical field of massage bed control, and in particular to a massage and sleep-aiding control system of an intelligent bed. Background Art

[0002] In modern society, people are facing increasing life and work pressure, and the problem of sleep quality is becoming more and more prominent. Massage, as a traditional and effective way of relaxation, can help people relieve fatigue and relax their body and mind by stimulating the human body's acupuncture points, relieving muscle tension, and promoting blood circulation. It has a positive effect on improving sleep quality. With the development of science and technology, massage beds have gradually shifted from manual massage to electric massage, further improving the efficiency and convenience of massage. The massage beds on the market currently lack effective human body status monitoring and real-time adjustment mechanisms. Therefore, it is of great practical significance to develop an intelligent bed massage sleep-aid control system that can monitor the human body status in real time, accurately adjust massage parameters, and effectively solve the problem of human body deviation during massage. This can not only improve the effect of massage and provide users with a more comfortable and effective massage experience, but also improve people's sleep quality to a certain extent and promote physical and mental health.

[0003] For example, Chinese patent publication number: CN118295303A, the invention discloses a massage and sleep-aiding smart bed control method, control system, storage medium, mattress and smart bed, which solves the problems of single massage form and unsatisfactory relaxation effect in the prior art. The technical solution adopted is: by setting user and system parameters, different users and different user requirements can match corresponding massage modes and massage effects to ensure the massage sleep-aiding effect and / or refreshing effect, setting multiple massage stages and corresponding multiple massage combination methods and / or setting at least one of monitoring mode and waking-up massage, so that users can thoroughly relax and sleep before going to bed, which is conducive to improving sleep quality, and waking-up massage makes users more energetic, and the control system makes the operation simple and intelligent.

[0004] The prior art still has the following problems: The existing technology does not take into account that the vibration impact of the massage head itself during the massage process may cause the body to shift, resulting in a decrease in the accuracy of the massage head's massage of the acupoints. The existing technology cannot comprehensively consider multi-dimensional information such as pressure values ​​and the ups and downs distance of human joints, and cannot sense changes in the human body's state and make corresponding adjustments, affecting the massage effect. Summary of the invention

[0005] To this end, the present invention provides a massage and sleep-aid control system for a smart bed to overcome the problem that the prior art cannot comprehensively consider multi-dimensional information such as pressure values ​​and the ups and downs distance of human joints, and cannot perceive changes in human body states and make corresponding adjustments.

[0006] To achieve the above object, the present invention provides a massage and sleep-aiding control system for a smart bed, comprising: A pre-treatment module, which is used to determine a number of action release areas based on the massage head for massaging each acupoint as the center reference; An information extraction module, which is connected to the pre-treatment module, includes a plurality of pressure monitoring units distributed in the action release area for obtaining the pressure value on the massage bed surface and a joint monitoring unit for obtaining the ups and downs distance of the joint points of the human body; A state analysis module, which is connected to the information extraction module and is used to determine the state tendency category of each action release area based on the difference of the pressure values ​​in each action release area; A feature fusion module, which is connected to the information extraction module and the state analysis module respectively, and is used to determine the feature monitoring factors of each action release area based on the state tendency category, wherein the feature monitoring factors include a first state characterization parameter determined according to the fluctuation distance, or a second state characterization parameter determined according to the pressure value comparison of the action release area; A control module, which is connected to the feature fusion module, is used to determine the way to control the massage head of the key release area based on the feature monitoring factors, including: Selecting a key action release area according to the comparison of the first state characterizing parameter, and adjusting the massage intensity of the massage head in the key action release area; And based on the comparison of the second state characterization parameter, a key effect release area is screened, and a massage head that meets the control screening conditions is screened in the key effect release area to adjust the massage frequency.

[0007] Furthermore, a plurality of pressure monitoring units are symmetrically distributed in the action release area with the massage head as the center reference.

[0008] Furthermore, the state analysis module is used to determine the pressure value difference, wherein: The state analysis module obtains the pressure values ​​of several pressure monitoring units in each action release area at several moments within a preset monitoring period, determines the displacement tendency characterization vector at each moment according to the maximum pressure value at each moment, determines the vector angles of the displacement tendency characterization vectors corresponding to adjacent moments in time sequence, and calculates the angle average of several vector angles.

[0009] Furthermore, the state analysis module is used to determine the state tendency category of each action release area, wherein: The state analysis module compares the angle average value with the displacement tendency determination condition; According to the comparison result that the average value of the angle meets the displacement tendency determination condition, the state analysis module determines that the action release area is a first state tendency category; According to the comparison result that the average value of the angle does not meet the displacement tendency determination condition, the state analysis module determines that the action release area is a second state tendency category; The displacement tendency determination condition is that the average value of the angle does not exceed a preset angle comparison value.

[0010] Furthermore, the feature fusion module is used to determine the feature monitoring factors of each action release area, wherein: The feature fusion module is used to determine the first state characterization parameter according to the fluctuation distance according to the determination result that the action release area is of the first state tendency category; The feature fusion module is used to determine the second state characterization parameter according to the judgment result that the action release area is in the second state tendency category and according to the pressure value comparison of the action release area.

[0011] Furthermore, the feature fusion module is used to determine a first state characterization parameter, wherein: The feature fusion module obtains the fluctuation distance fluctuation value of the fluctuation distance of the human joint point within a preset monitoring period, calculates the average value of the fluctuation distance fluctuation values ​​of the human joint point within a plurality of preset monitoring periods, and determines the first state characterization parameter according to the average value of the fluctuation distance fluctuation values ​​of a plurality of human joint points within the action release area of ​​the first state tendency category, wherein the first state characterization parameter is positively correlated with the average value of each fluctuation distance fluctuation value; The fluctuation distance fluctuation value is determined based on the maximum fluctuation distance and the maximum fluctuation distance of the human joint point within several preset monitoring cycles. The fluctuation distance obtained by the joint monitoring unit is the distance from the human joint point to the surface of the massage bed.

[0012] Furthermore, the control module is used to select the action release area corresponding to the maximum value of the first state characterization parameter as the key action release area, and the reduction in massage intensity of the massage head in the key action release area is positively correlated with the maximum value of the first state characterization parameter.

[0013] Furthermore, the feature fusion module is used to determine the second state characterization parameter, wherein: The feature fusion module is used to obtain the pressure value difference of the pressure monitoring unit in the action release area of ​​the second state tendency category at each moment in the preset monitoring period, and determine the maximum pressure value difference as the second state characterization parameter of the action release area; The pressure value difference is the difference between the maximum pressure value and the minimum pressure value of the pressure monitoring unit at each moment in a preset monitoring period.

[0014] Furthermore, the control module is further used to select the action release area where the second state characterization parameter meets the key action screening condition as the key action release area, and select the massage heads meeting the control screening condition according to the massage frequency difference between each massage head in the key action release area and the remaining massage heads; Among them, the key effect screening condition is that the second state characterization parameter exceeds the preset second state characterization parameter comparison value; the control screening condition is that the average value of the massage frequency difference between each massage head and the other massage heads does not exceed the preset frequency difference threshold.

[0015] Furthermore, the control module is also used to adjust the massage frequency of the massage heads that meet the control screening conditions to increase the average value of the difference in massage frequency between two massage heads among the massage heads that meet the control screening conditions.

[0016] Compared with the prior art, the beneficial effects of the present invention are that the system is provided with a pre-treatment module, an information extraction module, a state analysis module, a feature fusion module and a control module, wherein a number of action release areas are determined by the pre-treatment module, the pressure value on the surface of the massage bed and the ups and downs distance of the human body joints are obtained by the information extraction module, the state tendency category of each action release area is determined by the state analysis module, the feature monitoring factors of each action release area are determined by the feature fusion module, and the way to control the massage head of the key action release area is determined by the control module, thereby realizing accurate perception of the human body state and making corresponding adjustments based on multi-dimensional information such as the pressure value on the surface of the massage bed and the ups and downs distance of the human body joints caused by the vibration impact of the massage head itself, thereby improving the massage effect.

[0017] Furthermore, the present invention can ensure that the pressure monitoring units are evenly arranged in all directions around the massage head by symmetrically arranging a plurality of pressure monitoring units in the action release area with the massage head as the center reference, so that the changes in the pressure value on the surface of the massage bed can be monitored timely and accurately.

[0018] Furthermore, the present invention constructs a displacement tendency characterization vector with the maximum pressure value at each moment, which provides an effective basis for quantifying the body's displacement direction. By calculating the angle of the vectors at adjacent moments in time sequence, the changes in the body's displacement direction at consecutive moments are converted into measurable values, so that the slight displacement of the body during the massage process can be accurately presented. When the angle average value does not exceed the preset angle comparison value, it indicates that the displacement directions at consecutive moments are almost consistent, and the direction of the accumulated displacement deviation of the massage head vibration is relatively stable. When the angle average value exceeds the preset value, it indicates that the displacement direction is highly variable. Furthermore, the pressure value information on the surface of the massage bed caused by the vibration impact of the massage head itself can be accurately obtained.

[0019] Furthermore, the present invention determines targeted characteristic monitoring factors for action release areas of different state tendency categories, and determines the first state characterization parameter based on the ups and downs distance of human joints under the first state tendency category. It can be understood that when the action release area is determined to be the first state tendency category, that is, when the direction of the accumulated displacement deviation of the massage head vibration is stable, the ups and downs distance fluctuation value is determined by obtaining the maximum and minimum values ​​of the ups and downs distance of the joints within a preset monitoring period, and the average value of the fluctuation value within multiple periods is calculated. This can accurately capture the true dynamics of human joint activities, establish a positive correlation between the first state characterization parameter and the average value of each ups and downs distance fluctuation value, so that the degree of displacement influence caused by the massage on the body can be quantified, and then, based on the pressure value on the surface of the massage bed caused by the vibration impact of the massage head itself and the ups and downs distance of the human joints and other multi-dimensional information, accurate perception of the human body state is achieved, providing a basis for precise control of massage parameters.

[0020] Furthermore, the present invention can accurately locate the area where the displacement of the human body is the greatest during the massage process by screening the action release area corresponding to the maximum value of the first state characterization parameter as the key action release area. The greater the displacement of the human body in this area during the massage, the greater the reduction in massage intensity. This dynamic adjustment can avoid excessive displacement of the body due to excessive massage intensity, and further, realizes accurate perception of the human body state and corresponding adjustment based on multi-dimensional information such as the pressure value on the surface of the massage bed caused by the vibration impact of the massage head itself and the ups and downs distance of the human body joints, thereby improving the massage effect.

[0021] Furthermore, the present invention obtains the difference in pressure values ​​of the pressure monitoring unit at each moment in a preset monitoring period in the action release area of ​​the second state tendency category, and by calculating the difference between the maximum pressure value and the minimum pressure value at each moment, it is able to keenly capture the fluctuation of pressure changes, and determines the maximum pressure value difference as the second state characterization parameter, thereby realizing quantification of the degree of unstable displacement phenomenon, and further, realizing accurate perception of the human body state based on multi-dimensional information such as the pressure value on the surface of the massage bed caused by the vibration impact of the massage head itself and the ups and downs distance of the human body joints, providing a basis for precise control of massage parameters.

[0022] Furthermore, the present invention accurately identifies the action release areas with obvious unstable displacement phenomena and determines them as key action release areas, optimizes the working frequencies of the massage heads in these areas, reduces displacement accumulation, and screens out massage heads that are prone to uncertain directional displacement during vibration massage. It can be understood that if the frequencies of the massage heads that are prone to uncertain directional displacement are similar, the body displacement will be more complicated, the accumulated displacement error will increase, and the massage effect will be affected. Increasing the frequency difference between these massage heads can break the complex displacement superposition caused by the same or similar frequencies, and the displacement trends can be balanced to reduce the accumulation of complex displacement errors, thereby ensuring that the massage heads can continuously and stably act on the target acupuncture points. Furthermore, based on multi-dimensional information such as the pressure value on the surface of the massage bed caused by the vibration impact of the massage head itself and the ups and downs distance of the human body joints, the human body state can be accurately sensed and corresponding adjustments can be made, thereby improving the massage effect.

[0028] See also Figure 1 As shown, it is a system block diagram of a massage and sleep-aiding control system of a smart bed according to an embodiment of the present invention. The massage and sleep-aiding control system of the smart bed according to the present invention comprises: A pre-treatment module, which is used to determine a number of action release areas based on the massage head for massaging each acupoint as the center reference; Specifically, the present invention does not limit the specific structure of the pre-treatment module. It takes the massage head as the center and defines the corresponding action release area 1 according to the sensing range of the pressure monitoring unit 2. It can be a data processor that can realize the above functions, which will not be repeated here.

[0029] Specifically, in the present invention, the action release area is determined based on the massage head as a reference. In implementation, a circular action release area with a preset radius value can be determined with the massage head as the center reference 3. The preset radius value ranges from [3, 8], and the interval unit is cm. Preferably, the preset radius value can be 5 cm.

[0030] An information extraction module, which is connected to the pre-treatment module, includes a plurality of pressure monitoring units 2 distributed in the action release area 1 for obtaining the pressure value on the massage bed surface and a joint monitoring unit for obtaining the ups and downs distance of the joint points of the human body; Specifically, the present invention does not limit the specific structure of the pressure monitoring unit 2, which can be a piezoresistive pressure sensor. When the surface of the massage bed is subjected to pressure, the resistance value of the piezoresistive sensor changes with the pressure, causing the current or voltage passing through the sensor to change, which is then converted into a digital signal by an analog-to-digital conversion circuit, and finally the corresponding pressure value is calculated. This is a prior art and will not be repeated here.

[0031] Specifically, the present invention does not limit the specific structure of the joint monitoring unit, which can be composed of a laser transmitter, a laser receiver, a signal processing circuit and a control circuit. The laser transmitter is used to emit a laser beam to the joints of the human body, and the laser receiver is responsible for receiving the laser signal reflected from the joints. The signal processing circuit is used to amplify, filter and other processes on the received signal to extract information related to the distance. This is a prior art and will not be repeated here.

[0032] A state analysis module, which is connected to the information extraction module and is used to determine the state tendency category of each action release area based on the difference of the pressure values ​​in each action release area; Specifically, the present invention does not limit the state analysis module, which can be a microprocessor and a storage unit connected to the microprocessor. The storage unit is used to store program codes, pressure value data, and related judgment rules and parameters. The microprocessor is used to execute various algorithms and logical operations according to the data in the storage unit, which will not be repeated here.

[0033] A feature fusion module, which is connected to the information extraction module and the state analysis module respectively, and is used to determine the feature monitoring factors of each action release area based on the state tendency category, wherein the feature monitoring factors include a first state characterization parameter determined according to the fluctuation distance, or a second state characterization parameter determined according to the pressure value comparison of the action release area 1; Specifically, the present invention does not limit the feature fusion module, which can be composed of a microprocessor and a data interface. The microprocessor executes the processing rules stored in the ROM and outputs the determined feature monitoring factors to the control module through the data interface, which will not be repeated here.

[0034] A control module, which is connected to the feature fusion module, is used to determine the way to control the massage head of the key release area based on the feature monitoring factors, including: Selecting a key action release area according to the comparison of the first state characterizing parameter, and adjusting the massage intensity of the massage head in the key action release area; And based on the comparison of the second state characterization parameter, a key effect release area is screened, and a massage head that meets the control screening conditions is screened in the key effect release area to adjust the massage frequency.

[0035] Specifically, the massage intensity in the present invention can be the bulging stroke of the massage head relative to the surface of the massage bed during a single massage. The greater the bulging stroke, the greater the stroke of the massage head pressing on the skin surface. The massage frequency is the vibration or patting frequency of the massage head, which is generally 30-90 times / minute. The massage intensity and massage frequency are technical parameters commonly used by technicians in this field and will not be described in detail here.

[0036] Specifically, the present invention does not limit the implementation method of regulating the massage frequency and massage intensity of the massage head. It is well known to those skilled in the art that the structure that drives the massage head to move is generally a connecting shaft and a variable frequency motor. The massage frequency of the massage head is regulated by adjusting the rotational speed of the variable frequency motor. The bulging stroke of the massage head can be determined by adjusting the eccentricity of the eccentric wheel between the connecting shaft and the massage head. The bulging stroke of the massage head can also be adjusted by a multi-stage transmission mechanism of the connecting shaft according to different transmission ratios corresponding to different transmission levels. This is a prior art and will not be repeated here.

[0037] Specifically, the present invention does not limit the specific structure of the control module, which can be composed of logic components. The logic components can be field programmable logic components, microprocessors, processors used in computers, etc., which will not be repeated here.

[0038] Specifically, a plurality of pressure monitoring units 2 are symmetrically distributed in the action release area 1 with the massage head as the central reference 3 .

[0039] Preferably, in the present invention, eight pressure monitoring units 2 may be arranged at intervals of 45° from each other. Figure 2 As shown, it is a schematic diagram of the distribution of several pressure monitoring units 2 in the action release area of ​​an embodiment of the present invention. The pressure monitoring units a, b, c, d, e, f, g, and h are symmetrically distributed in the action release area 1 with the massage head as the center reference 3.

[0040] Specifically, the present invention can ensure that the pressure monitoring units 2 are evenly arranged in all directions around the massage head by symmetrically arranging a plurality of pressure monitoring units 2 in the action release area 1 with the massage head as the central reference 3, so as to timely and accurately monitor the changes in the pressure value on the surface of the massage bed.

[0041] Specifically, the state analysis module is used to determine the pressure value difference, wherein: The state analysis module obtains the pressure values ​​of several pressure monitoring units 2 in each action release area at several moments within a preset monitoring period, determines the displacement tendency characterization vector at each moment according to the maximum pressure value at each moment, determines the vector angles of the displacement tendency characterization vectors corresponding to adjacent moments in time sequence, and calculates the angle average of several vector angles.

[0042] Specifically, the longer the preset monitoring period of the present invention is set, the more pressure values ​​​​acquired by the pressure monitoring unit 2, the more displacement tendency characterization vectors obtained, and the higher the monitoring accuracy. Preferably, a preferred value of the preset monitoring period is provided here. The preset monitoring period can be 8s. The intervals at each moment when the pressure monitoring unit obtains the pressure value are set in the range of [0.8, 2], and the interval unit is s. Preferably, the pressure value of the pressure monitoring unit can be obtained every 1s in order to avoid the large amount of calculation data due to too small values ​​and the inaccuracy of detection accuracy caused by too large values.

[0043] Specifically, the vector end point of the displacement tendency characterization vector in the present invention is the position of the pressure monitoring unit corresponding to the maximum pressure value at each moment, and the vector start point of the displacement tendency characterization vector is the position of the massage head.

[0044] Specifically, see Figure 3 As shown, it is a logic flow chart of the state analysis module of the embodiment of the present invention for determining the state tendency category of each action release area, wherein the state analysis module is used to determine the state tendency category of each action release area, wherein: The state analysis module compares the angle average value with the displacement tendency determination condition; According to the comparison result that the average value of the angle meets the displacement tendency determination condition, the state analysis module determines that the action release area 1 is a first state tendency category; According to the comparison result that the average value of the angle does not meet the displacement tendency determination condition, the state analysis module determines that the action release area 1 is a second state tendency category; The displacement tendency determination condition is that the average value of the angle does not exceed a preset angle comparison value.

[0045] Specifically, the preset angle comparison value in the present invention can be determined based on the historical data, in which the same massage head is used in several massage processes, according to the average value of the vector angles of the displacement tendency characterization vectors at adjacent moments in the displacement tendency characterization vectors at consecutive moments to determine the angle comparison value. In order to effectively distinguish the displacement direction performance of the action release area according to the size of the vector angle, the preset angle comparison value has a value range of [30°, 75°]. Preferably, the preset angle comparison value is 60°.

[0046] Specifically, the present invention constructs a displacement tendency characterization vector with the maximum pressure value at each moment, which provides an effective basis for quantifying the body's displacement direction. By calculating the angle of the vectors at adjacent moments in time sequence, the changes in the body's displacement direction at consecutive moments are converted into measurable values, so that the slight displacement of the body during the massage process can be accurately presented. When the angle average value does not exceed the preset angle comparison value, it indicates that the displacement directions at consecutive moments are almost consistent, and the direction of the accumulated displacement deviation of the massage head vibration is relatively stable. When the angle average value exceeds the preset value, it indicates that the displacement direction is highly variable. Furthermore, the pressure value information on the surface of the massage bed caused by the vibration impact of the massage head itself can be accurately obtained.

[0047] Specifically, the feature fusion module is used to determine the feature monitoring factors of each action release area, wherein: The feature fusion module is used to determine the first state characterization parameter according to the fluctuation distance according to the determination result that the action release area 1 is the first state tendency category; The feature fusion module is used to determine the second state characterization parameter according to the comparison of the pressure values ​​of the action release area according to the judgment result that the action release area 1 is of the second state tendency category.

[0048] Specifically, the feature fusion module is used to determine the first state characterization parameter, wherein: The feature fusion module obtains the fluctuation distance fluctuation value of the fluctuation distance of the human joint point within a preset monitoring period, calculates the average value of the fluctuation distance fluctuation values ​​of the human joint point within a plurality of preset monitoring periods, and determines the first state characterization parameter according to the average value of the fluctuation distance fluctuation values ​​of a plurality of human joint points within the action release area of ​​the first state tendency category, wherein the first state characterization parameter is positively correlated with the average value of each fluctuation distance fluctuation value; The fluctuation distance fluctuation value is determined based on the maximum fluctuation distance and the maximum fluctuation distance of the human joint point within several preset monitoring cycles. The fluctuation distance obtained by the joint monitoring unit is the distance from the human joint point to the surface of the massage bed.

[0049] Specifically, the present invention does not limit the calculation method of the first state characterization parameter. The first state characterization parameter is positively correlated with the average value of each undulation distance fluctuation value. Preferably, the first state characterization parameter can be the average value of each undulation distance fluctuation value multiplied by their respective weight coefficients, and the resultant value is added. The weight coefficients corresponding to the average values ​​of each undulation distance fluctuation value can be set to equal coefficients, and the sum of the weight coefficients is 1.

[0050] Specifically, the present invention determines the characteristic monitoring factors for the action release areas of different state tendency categories in a targeted manner, and determines the first state characterization parameter based on the ups and downs distance of the human body joints under the first state tendency category. It can be understood that when the action release area is determined to be the first state tendency category, that is, when the direction of the accumulated displacement deviation of the massage head vibration is stable, the ups and downs distance fluctuation value is determined by obtaining the maximum and minimum values ​​of the ups and downs distance of the joints within a preset monitoring period, and the average value of the fluctuation value within multiple periods is calculated. This can accurately capture the real dynamics of the human body joint movement, establish a positive correlation between the first state characterization parameter and the average value of each ups and downs distance fluctuation value, so that the degree of displacement influence caused by the massage on the body can be quantified, and then, according to the multi-dimensional information such as the pressure value on the surface of the massage bed caused by the vibration impact of the massage head itself and the ups and downs distance of the human body joints, it is realized to accurately perceive the human body state, and provide a basis for accurately controlling the massage parameters.

[0051] Specifically, the control module is used to select the action release area corresponding to the maximum value of the first state characterization parameter as the key action release area, and the reduction in massage intensity of the massage head in the key action release area is positively correlated with the maximum value of the first state characterization parameter.

[0052] Specifically, the present invention can accurately locate the area where the displacement of the human body is the greatest during the massage process by screening the action release area corresponding to the maximum value of the first state characterization parameter as the key action release area. The greater the displacement of the human body in this area during the massage, the greater the reduction in massage intensity. This dynamic adjustment can avoid excessive displacement of the body due to excessive massage intensity, and further, realizes accurate perception of the human body state and corresponding adjustment based on multi-dimensional information such as the pressure value on the surface of the massage bed caused by the vibration impact of the massage head itself and the ups and downs distance of the human body joints, thereby improving the massage effect.

[0053] Specifically, the feature fusion module is used to determine the second state characterization parameter, wherein: The feature fusion module is used to obtain the pressure value difference of the pressure monitoring unit in the action release area of ​​the second state tendency category at each moment in the preset monitoring period, and determine the maximum pressure value difference as the second state characterization parameter of the action release area; The pressure value difference is the difference between the maximum pressure value and the minimum pressure value of the pressure monitoring unit 2 at each moment in a preset monitoring period.

[0054] Specifically, see Figure 4As shown, it is a logic flow chart of the control module of the embodiment of the present invention for selecting massage heads that meet the control screening conditions, the control module is also used to select the action release area where the second state characterization parameter meets the key action screening condition as the key action release area, and select the massage heads that meet the control screening condition according to the massage frequency difference between each massage head in the key action release area and the rest of the massage heads; Among them, the key effect screening condition is that the second state characterization parameter exceeds the preset second state characterization parameter comparison value; the control screening condition is that the average value of the massage frequency difference between each massage head and the other massage heads does not exceed the preset frequency difference threshold.

[0055] Specifically, in the present invention, the preset second-state characterization parameter comparison value can be determined based on historical data, and the average value of the second-state characterization parameter in the action release area corresponding to each massage head during the massage process of several massage heads is obtained in advance, and the second-state characterization parameter comparison value is determined according to the calculated average value of the second-state characterization parameter. In order to effectively screen out areas with obvious unstable shift phenomena according to the maximum pressure value difference among the pressure value differences of the pressure monitoring unit 2 at each moment within the preset monitoring period, and considering the different pressure values ​​monitored by users of different weights, the value range of the second-state characterization parameter comparison value can be set to [3, 7], and the interval unit is N. Here is a preferred value, and the preset second-state characterization parameter comparison value is 4N.

[0056] Specifically, the frequency difference threshold preset in the present invention can be set by a person skilled in the art. The larger the value of the frequency difference threshold, the more massage heads that meet the control screening conditions are screened out, that is, the more massage heads that perform frequency control. In order to avoid the frequency control effect of too few massage heads being insignificant, and the frequency control of too many massage heads affecting the massage feeling of the human body, the frequency difference threshold preset in the present invention has a value range of [3, 10], and the interval unit is times / minute. Preferably, the frequency difference threshold is 5 times / minute.

[0057] Specifically, the present invention obtains the difference in pressure values ​​of the pressure monitoring unit 2 at each moment within a preset monitoring period in the action release area of ​​the second state tendency category, and by calculating the difference between the maximum pressure value and the minimum pressure value at each moment, it is able to keenly capture the fluctuation of pressure changes, and determines the maximum pressure value difference as the second state characterization parameter, thereby realizing quantification of the degree of unstable displacement phenomenon, and further realizing accurate perception of the human body state based on multi-dimensional information such as the pressure value on the surface of the massage bed caused by the vibration impact of the massage head itself and the ups and downs distance of the human body joints, providing a basis for precise control of massage parameters.

[0058] Specifically, the control module is further used to adjust the massage frequency of the massage heads that meet the control screening conditions to increase the average value of the difference in massage frequency between two massage heads among the massage heads that meet the control screening conditions.

[0059] Specifically, increasing the average value of the difference in massage frequency between two massage heads that meet the control screening conditions can be achieved by increasing the massage frequency of the massage head with the highest current massage frequency among the massage heads that meet the control screening conditions, and decreasing the massage frequency of the massage head with the lowest current massage frequency among the massage heads that meet the control screening conditions. The amount of increase or decrease in the massage frequency can be set in advance, and a preferred value for setting the amount of increase or decrease in the massage frequency is provided herein, and the amount of increase or decrease in the massage frequency can be set to 2 times / minute.

[0060] For example, if there are currently three massage heads that meet the control and filtering conditions, and their massage frequencies are 40 times / minute, 44 times / minute, and 41 times / minute, respectively, the control module can increase the massage frequency of the massage head with the highest current massage frequency among the three massage heads that meet the control and filtering conditions, that is, increase the massage frequency of the massage head from 44 times / minute to 46 times / minute. The control module also needs to reduce the massage frequency of the massage head with the lowest current massage frequency among the three massage heads that meet the control and filtering conditions, that is, reduce the massage frequency of the massage head from 40 times / minute to 38 times / minute. After this adjustment, the average value of the difference in massage frequency between two massage heads among the three massage heads that currently meet the control and filtering conditions increases by 2.7 times / minute.

[0061] Specifically, the present invention accurately identifies the action release areas where unstable displacement phenomena are obvious, and determines them as key action release areas, optimizes the working frequencies of the massage heads in these areas, reduces displacement accumulation, and screens out massage heads that are prone to uncertain directional displacement during vibration massage. It can be understood that if the frequencies of the massage heads that are prone to uncertain directional displacement are similar, the body displacement will be more complicated, the accumulated displacement error will increase, and the massage effect will be affected. Increasing the frequency difference between these massage heads can break the complex displacement superposition caused by the same or similar frequencies, and the displacement trends can be balanced to reduce the accumulation of complex displacement errors, thereby ensuring that the massage heads can continuously and stably act on the target acupuncture points. Furthermore, based on multi-dimensional information such as the pressure value on the surface of the massage bed caused by the vibration impact of the massage head itself and the ups and downs distance of the human body joints, the human body state can be accurately sensed and corresponding adjustments can be made, thereby improving the massage effect.
