The wearable detection device is a kind of vital sign monitoring equipment that can be worn on the body of a wearer, and compared with the conventional vital sign monitoring equipment, such as a sphygmomanometer, the wearable detection device has the advantages of small size, portability, and the like. The degree of tightness that the person of wearing needs manual regulation wearable detection device among the prior art, if adjust too slowly can lead to the dropping of wearable detection device, if adjust too fast can cause limbs discomfort again, consequently is difficult to control speed of adjustment.
In order to overcome the defects in the prior art, the invention provides a method for regulating the stretching speed of a wearable detection device, which comprises the steps of obtaining inertia measurement data of a wearer corresponding to the wearable detection device, and determining a falling risk value corresponding to the wearable detection device according to the inertia measurement data, wherein the wearable detection device comprises a fixed frame, and a plurality of stretching units are arranged in the fixed frame; acquiring an electromyographic signal corresponding to the wearer, and determining a tightness variation corresponding to the wearable detection device according to the electromyographic signal, wherein the tightness variation is used for reflecting the variation of pressure applied to the limb of the wearer; and determining the stretching speed corresponding to each stretching unit according to the falling risk value and the elasticity variation. The invention adjusts the degree of tightness by controlling the telescopic unit in the wearable detection device, and adjusts the telescopic speed of the telescopic unit by calculating the current falling risk value and the variable quantity of the degree of tightness. The problem of among the prior art the person's of wearing manual regulation wearing formula detection device elasticity degree, be difficult to control speed regulation is solved.
As shown in fig. 1, the method includes:
step S100, inertial measurement data of a wearer corresponding to the wearable detection device are obtained, and a falling risk value corresponding to the wearable detection device is determined according to the inertial measurement data, wherein the wearable detection device comprises a fixing frame, and a plurality of telescopic units are arranged in the fixing frame.
Specifically, wearing formula detection device's in this embodiment main body frame is the mount, has set up a plurality of flexible units in the mount, can tighten up and relax wearing formula detection device through adjusting the flexible volume of each flexible unit. The inertial measurement data may reflect the current movement state of the wearer, and the movement state of the wearer may affect the stability of the binding between the wearable detection device and the limb, for example, the wearer may not affect the binding between the wearable detection device and the limb when moving slowly, but may cause the wearable detection device to be detached from the limb when moving rapidly. Therefore, the falling risk value of the wearable detection device can be calculated according to the inertia measurement data, so that the tightness degree of the wearable detection device can be adjusted in time, and the wearable detection device is prevented from being separated from limbs.
In one implementation, the step S100 specifically includes:
step S101, determining speed change data and direction change data corresponding to the wearer according to the inertia measurement data, wherein the speed change data are used for reflecting speed change rates corresponding to all time points respectively, and the direction change data are used for reflecting direction change amounts corresponding to all time points respectively;
and S102, determining the falling risk value according to the speed change data and the direction change data.
Specifically, since the inertial measurement unit mainly includes an accelerometer and a gyroscope, the inertial measurement data includes acceleration data and gyroscope data. The speed change rate of the wearer at different time points can be analyzed according to the acceleration data, and the speed change data can be obtained. The direction variation (variation of the advancing angle) of the wearer at different time points can be analyzed according to the gyroscope data, and then the direction variation data can be obtained. Through the speed change data and the direction change data, the complexity of the movement change of the wearer can be analyzed. Due to inertia, the more complex the movement change of the wearer is, the higher the possibility that the wearable detection device is thrown away, and therefore the falling risk value of the wearable detection device can be calculated from the speed change data and the direction change data.
In an implementation manner, the step S102 specifically includes:
step S1021, determining state fluctuation data corresponding to the wearer according to the speed change data and the direction change data, wherein the state fluctuation data comprise state fluctuation values respectively corresponding to each time point, and the state fluctuation value corresponding to each time point is determined based on the speed change rate and the direction change amount corresponding to the time point;
step S1022, obtaining a ratio of time points in the state fluctuation data at which the state fluctuation value is higher than a preset threshold;
and S1023, determining the falling risk value according to the proportion.
Specifically, for each time point, the higher the speed change rate and/or the direction change amount at that time point, the greater the degree of body swing of the wearer is indicated. It should be noted that the simultaneous change of two parameters, namely the speed change rate and the direction change amount, has a larger influence on the body swing degree than the change of a single parameter. Therefore, the body swing degree corresponding to the time point can be analyzed according to the speed change rate and the direction change amount of the time point, and the body swing degree can be quantitatively presented in a state fluctuation value mode. After the state fluctuation value of each time point is calculated, the time points of which the state fluctuation value is higher than a preset threshold value are statistically analyzed, and the time points reflect the moment when the body swing degree of the wearer is too high. The proportion is obtained by calculating the proportion of the time points at all the time points, and the higher the proportion is, the more violent the swing of the body of the wearer is represented, and the higher the falling risk value of the wearable detection device is.
In an implementation manner, the state fluctuation value corresponding to each time point is determined based on a weighted average value or a weighted sum of the speed change rate and the direction change amount corresponding to the time point, and weight values corresponding to the speed change rate and the direction change amount respectively may be determined according to a wearer's demand.
As shown in fig. 1, the method further comprises:
step S200, acquiring an electromyographic signal corresponding to the wearer, and determining a tightness variation corresponding to the wearable detection device according to the electromyographic signal, wherein the tightness variation is used for reflecting the variation of the pressure on the limb of the wearer.
In particular, an electromyographic signal is a bioelectrical signal which is a bioelectrical current generated by contraction of a surface muscle of a wearer. Therefore, the current muscle contraction condition of the wearer can be analyzed through the electromyographic signals, and whether the tightness degree of the wearable detection device needs to be adjusted or not at present and how to adjust the tightness degree can be further judged, and the variation quantity of the tightness degree can be obtained.
In one implementation, the step S200 specifically includes:
step S201, determining the actual motion state of the wearer according to the electromyographic signals;
step S202, determining the target tightness according to the actual motion state;
step S203, acquiring the actual tightness corresponding to the wearable detection device;
and step S204, determining the elasticity variation according to the target elasticity and the actual elasticity.
Specifically, since the electromyographic signal can reflect the muscle contraction condition of the wearer, and the current motion state of the wearer and the muscle contraction condition have a correlation, the current actual motion state of the wearer can be judged by analyzing the electromyographic signal. In the embodiment, the appropriate tightness corresponding to the different motion states is set in advance, so that the current required tightness of the wearer can be determined according to the actual motion state, and the target tightness can be obtained. And then the actual tightness and the target tightness of the current wearable detection device are compared, so that the tightness variation can be obtained.
As shown in fig. 1, the method further comprises:
and S300, determining the stretching speed corresponding to each stretching unit according to the falling risk value and the elasticity variation.
Specifically, the falling risk value may reflect the possibility that the wearable detection device is thrown away at present, and the higher the falling risk value is, the higher the possibility that the wearable detection device is thrown away is indicated, the tightness degree needs to be adjusted quickly to avoid the wearable detection device from being separated from the limb. In addition, the greater the amount of change in the degree of tightness, the greater the change in the degree of tightness of the wearable detection device, and the change in the degree of tightness is likely to cause discomfort to the limb. When the stretching speed of each stretching unit is determined, the current falling risk value and the elasticity variation of the wearable detection device need to be considered at the same time, so that the purposes of stabilizing the wearable detection device in time and reducing the discomfort of a wearer are achieved.
In an implementation manner, the step S300 specifically includes:
step S301, determining the corresponding adjusting time length of the wearable detection device according to the falling risk value;
step S302, determining target expansion and contraction amounts corresponding to all the expansion units respectively according to the elasticity variation, wherein each target expansion and contraction amount is determined based on an adjustment scheme with the minimum sum of the expansion and contraction amounts corresponding to the elasticity variation;
step S303, determining the stretching speed corresponding to each stretching unit according to the adjusting time length and the stretching amount corresponding to each stretching unit.
Specifically, the present embodiment sets the falling risk value to have an inverse relationship with the adjustment duration, that is, the higher the falling risk value is, the shorter the adjustment duration is. In other words, when the falling risk of the wearable detection device is high, the purpose of timely stabilizing the wearable detection device by shortening the adjustment time is needed. In addition, a plurality of adjustment schemes can be determined according to the amount of change in the degree of tightness, in order to reduce discomfort of the wearer, the present embodiment needs to calculate the sum of the expansion and contraction amounts of all the expansion and contraction units in each adjustment scheme, and the adjustment scheme with the smallest sum of the expansion and contraction amounts is relatively less likely to cause discomfort to the wearer, so that the adjustment scheme is taken as a target scheme, and the target expansion and contraction amount of each expansion and contraction unit is determined according to the target scheme. Each telescopic unit needs to realize the target telescopic amount in the calculated adjusting time length, so that for each telescopic unit, the telescopic speed of the telescopic unit can be obtained by dividing the target telescopic amount of the telescopic unit by the adjusting time length.
In one implementation manner, each telescopic unit is provided with an electrode module, the electrode module is used for acquiring vital sign data, each telescopic unit comprises an air pump and an air bag, and the air pump is used for inflating or evacuating the air bag.
Specifically, the telescopic unit in this embodiment actually comprises an air pump and an air bag, and the volume of air in the air bag can be changed by inflating or deflating the air bag with the air pump, so that the telescopic unit is telescopic.
In one implementation, the method further comprises:
and S400, determining the inflation speed or the air extraction speed of the air pump corresponding to each telescopic unit according to the telescopic speed corresponding to each telescopic unit.
Specifically, in the embodiment, the air pump inflates or deflates the airbag to change the air volume in the airbag, so that the expansion and contraction of the expansion and contraction unit are realized. Therefore, for each telescopic unit, the inflation speed/air extraction speed of the corresponding air pump can be calculated according to the corresponding telescopic speed.
In one implementation, as shown in fig. 2 and 3, the wearable detection device is a wearable detection head ring, and the head ring is composed of a bandage 101, an electrode module 102, a soft foam filling module 103, an air bag 104, a magnet 105, an air pump and a flexible circuit board.
