Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to better understand the human body impedance measuring method, device, electronic device and storage medium provided in the embodiments of the present application, the following description is first provided for an electronic device suitable for use in the embodiments of the present application.
Referring to fig. 1, fig. 1 is a diagram illustrating a structure example of an electronic device according to an embodiment of the present disclosure. The human body impedance measuring method provided by the embodiment of the application can be applied to the electronic device 100 shown in fig. 1. The electronic device 100 is used for measuring bio-impedance, and the electronic device 100 may be an electronic scale or a body composition analyzer, which is not limited in the embodiments of the present application. For convenience of description, the electronic device is an electronic scale.
As shown in fig. 1, the electronic device 100 includes at least four electrodes for measuring impedance of a human body, including a first contact electrode 102, a second contact electrode 104, a third contact electrode 106, and a fourth contact electrode 108. Wherein the first contact electrode 102 and the second contact electrode 104 are for contacting a first body part of the measurement object, for example, the first contact electrode 102 and the second contact electrode 104 may be for contacting a left foot of the measurement object, the third contact electrode 106 and the fourth contact electrode 108 are for contacting a second body part of the measurement object, for example, the third contact electrode 106 and the fourth contact electrode 108 may be for contacting a right foot of the measurement object. In a conventional human body impedance measurement process, when a measurement object is in contact with four electrodes, an excitation source inside the electronic device 100 outputs an excitation current to the measurement object through the first contact electrode 102 and the third contact electrode 106, the excitation current generates a voltage difference through an impedance network between a left foot and a right foot of a human body, the voltage difference between the left foot and the right foot of the human body is measured through a voltage measurement circuit fixedly connected with the second contact electrode 104 and the fourth contact electrode 108, and a human body impedance value can be obtained by converting the voltage difference and an excitation current signal, so that human body impedance measurement is realized.
However, the coverage of the four electrodes varies depending on the position at which the measurement object stands on the scale body, and thus the measurement result varies every time the impedance of the human body is measured. Meanwhile, the inventor researches to find that the measured human body impedance is minimum when the feet of the measuring object are close to the front, namely the toes of the feet are closer to the edge of the scale; the body impedance measured is greatest when the feet are measured to be back, i.e., the heels of the feet are closer to the edge of the scale.
Based on the above problems, the inventor proposes a method and an apparatus for measuring human body impedance, an electronic device, and a storage medium in the embodiments of the present application, and determines a standing position of a measurement object by obtaining different impedance data measured in a plurality of circuit connection modes, so as to compensate a human body impedance value and improve consistency of human body impedance measurement.
The electronic device is only an example for convenience of understanding, and it is to be understood that the embodiment of the present application is not limited to the structure of the electronic device.
The following describes in detail the human body impedance measurement method, apparatus, electronic device and storage medium provided in the embodiments of the present application with specific embodiments.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a method for measuring a body impedance according to an embodiment of the present application, and the method is applied to the electronic device. The flow shown in fig. 2 will be described in detail below. The above-mentioned human body impedance measuring method may specifically include the steps of:
step S110: and acquiring a first impedance parameter, wherein the first impedance parameter is obtained by measuring a measurement object by the electronic equipment based on a first circuit connection mode.
Step S120: and obtaining a second impedance parameter, wherein the second impedance parameter is obtained by measuring the measurement object by the electronic equipment based on the second circuit connection mode.
Step S130: and obtaining a third impedance parameter, wherein the third impedance parameter is obtained by measuring the measurement object by the electronic equipment based on a third circuit connection mode.
At present, when the human body impedance is measured, because the standing positions of the human body on the electronic equipment are different, the human body impedance value is different and the consistency is poor when the human body impedance is measured at each time. Therefore, in this embodiment, a plurality of impedance parameters may be obtained, and an impedance compensation value is obtained according to the plurality of impedance parameters for compensation, so as to obtain a compensated impedance value as a target impedance parameter.
The first circuit connection mode, the second circuit connection mode and the third circuit connection mode are different. One of the first circuit connection mode, the second circuit connection mode and the third circuit connection mode is the same as the circuit connection relation in the traditional human body impedance measurement process. That is, any one of the first circuit connection method, the second circuit connection method, and the third circuit connection method is: two contact electrodes are respectively connected with the excitation source, and the other two contact electrodes are respectively connected with the voltage measuring circuit. Correspondingly, two other connection modes different from the connection mode may be: and one of the two contact electrodes is simultaneously connected with the excitation source and the voltage measuring circuit, and the other contact electrode is suspended. For example, as shown in fig. 1, the electronic device may include a first contact electrode 102, a second contact electrode 104, a third contact electrode 106, and a fourth contact electrode 108, wherein the first circuit connection manner may be the same as the circuit connection relationship in the conventional human body impedance measurement process, that is, the first contact electrode 102 and the third contact electrode 106 are respectively connected to the excitation source, the second contact electrode 104 and the fourth contact electrode 108 are respectively connected to the voltage measurement circuit, and the measurement object is measured based on the first circuit connection manner, so as to obtain the first impedance parameter.
In some embodiments, the first contact electrode 102 and the second contact electrode 104 may be in contact with a left foot of a user, the third contact electrode 106 and the fourth contact electrode 108 may be in contact with a right foot of the user, for example, the left foot, the second circuit connection manner may be that the first contact electrode 102 is simultaneously connected with the excitation source and the voltage measurement circuit, the second contact electrode 104 is suspended, and a second impedance parameter may be obtained by measuring a measurement object based on the second circuit connection manner.
In some embodiments, taking the left foot as an example, the third circuit connection manner may be that the second contact electrode 104 is simultaneously connected to the excitation source and the voltage measurement circuit, the first contact electrode 102 is suspended, and the third impedance parameter may be obtained by measuring the measurement object based on the third circuit connection manner.
Further, the acquiring order of the first impedance parameter, the second impedance parameter and the third impedance parameter may be flexibly adjusted, and is not limited to the above order.

In this embodiment, after the first impedance parameter, the second impedance parameter, and the third impedance parameter are obtained, the impedance compensation parameter may be obtained based on the first impedance parameter, the second impedance parameter, and the third impedance parameter.
In some embodiments, the contact impedance between the human body and the electrode may be obtained according to the first impedance parameter, the second impedance parameter, and the third impedance parameter, the standing position of the measurement object on the electronic device may be determined according to the contact impedance, and then the corresponding impedance compensation parameter may be obtained according to the standing position. For example, if the standing position of the measurement object in the electronic device is forward compared with the standard standing position according to the first impedance parameter, the second impedance parameter, and the third impedance parameter, the impedance compensation parameter may be +5 Ω; if the standing position of the measurement object at the electronic device is located forward compared to the standard standing position, the impedance compensation parameter may be-5 Ω.
In some embodiments, a mapping relationship may be preset, the mapping relationship may include a plurality of first impedance parameters, a plurality of second impedance parameters, and a plurality of third impedance parameters and a plurality of impedance compensation parameters, and the impedance compensation parameters corresponding to the obtained first impedance parameters, second impedance parameters, and third impedance parameters may be obtained based on the mapping relationship.
In some embodiments, an average of the first impedance parameter, the second impedance parameter, and the third impedance parameter may be calculated, and a difference between the first impedance parameter and the average may be used as the impedance compensation parameter. The above-mentioned manner of obtaining the impedance compensation parameter is only an example and is not limited herein.
Step S150: and compensating the first impedance parameter based on the impedance compensation parameter to obtain a target impedance parameter.
In this embodiment, the first impedance parameter may be compensated based on the impedance compensation parameter to obtain the target impedance parameter. In some embodiments, the impedance compensation parameter may be added to the first impedance parameter to obtain the target impedance parameter. In some embodiments, the target impedance parameter may also be obtained by subtracting the first impedance parameter from the impedance compensation parameter. And is not limited herein.

As will be described in detail with respect to the flow shown in fig. 8, the method may specifically include the following steps:
step S3721: and when the first impedance proportion parameter is smaller than the first threshold value, taking a multiple of the impedance compensation base number which is larger than zero as the first impedance compensation parameter.
In this embodiment, the first impedance proportion parameter may correspond to a position of a human body on the electronic device, and taking an electronic scale as an example, the first impedance proportion parameter has a positive correlation with the front and back of a standing position of the human body on the scale body, that is, the earlier the standing position is, the smaller the first impedance proportion parameter is, and the later the standing position is, the larger the first impedance proportion parameter is. Therefore, the first threshold and the second threshold may be preset according to the position before and after the station, for example, when the station is near, the first impedance ratio parameter is measured to be less than 1, the first threshold may be set to be 1, when the station is near, the first impedance ratio parameter is measured to be greater than 6, and the second threshold may be set to be 6. The setting of the first threshold and the second threshold is merely an example, and is not limited herein. Wherein the first threshold is less than the second threshold.
In some embodiments, when the first impedance proportion parameter is smaller than the first threshold value, a multiple of the impedance compensation base number larger than zero may be taken as the first impedance compensation parameter. Specifically, the first impedance proportion parameter obtained by the calculation is compared with the first threshold value, and when the first impedance proportion parameter is smaller than the first threshold value, it can indicate that the standing position of the measurement object on the scale body is advanced, and as can be seen from the above, when the standing position is advanced, the measured human body impedance value is small, and it is necessary to increase the measured human body impedance value, so a multiple of the impedance compensation base number larger than zero may be taken as the first impedance compensation parameter, and for example, when the impedance compensation base number is 10 ohms, 10 ohms may be taken as the first impedance compensation parameter, and 15 ohms may be taken as the first impedance compensation parameter.
Step S3722: and when the first impedance proportion parameter is larger than a second threshold value, taking a multiple of the impedance compensation base number which is smaller than zero as the first impedance compensation parameter, wherein the second threshold value is larger than the first threshold value.
In some embodiments, when the first impedance proportion parameter is greater than the second threshold, a multiple of the impedance compensation base that is less than zero is taken as the first impedance compensation parameter. Specifically, the first impedance proportion parameter obtained by the calculation may be compared with a second threshold, and when the first impedance proportion parameter is greater than the second threshold, it may indicate that the position of the measurement object on the scale body is behind, and as can be seen from the above, when the position is behind, the measured human impedance value is large, and the measured human impedance value needs to be reduced, so a multiple of the impedance compensation base number smaller than zero may be taken as the first impedance compensation parameter, for example, when the impedance compensation base number is 8 ohms, 8 ohms may be taken as the first impedance compensation parameter, 16 ohms may be taken as the first impedance compensation parameter, and the like.
In some embodiments, the first impedance proportion parameter is compared with a first threshold and a second threshold, and when the first impedance proportion parameter is greater than the first threshold and less than the second threshold, the measured human body impedance value may not be compensated, that is, the first impedance compensation parameter may take zero.
