Obviously, the described embodiments are part of the embodiments of the present invention. , not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The following describes the physiological signal acquisition system and method of the present invention with reference to FIG. 1 to FIG. 6 .

As shown in FIG. 1 and FIG. 4 , the present invention provides a physiological signal collection system, and the physiological signal collection system includes: at least two wearing tags 10 and a control terminal 30 .

The number of wearing tags 10 can be multiple, and the number of wearing tags 10 can be 2 to 12, such as 5. Multiple wearing tags 10 can be worn on a living body, and the living body can be a human body or other animal bodies. , such as certain livestock or pets.

The wearable tag 10 has acquisition means for acquiring target physiological signals and an independent synchronization counter 12 .

The wearing tag 10 may have a collection device, and the collection device may be used to collect target physiological signals. The target physiological signals are physiological characteristics of the organism itself, such as body temperature, heart rate, blood oxygen concentration, blood pressure and other physiological characteristics.

The wearing tag 10 may have a fitting piece, and the fitting piece may be fitted to the target position of the living body, for example, it may be fitted on the forehead or the wrist for monitoring body temperature, and it may also be fitted on the chest for monitoring the heart rate.

The independent synchronization counter 12 is a digital component in the digital system that counts the number of pulses to realize digital measurement, operation and control. The independent synchronization counter 12 can be used to give a time stamp, and is installed on each wearing tag 10. If there are independent synchronization counters 12, then the independent synchronization counters 12 of multiple wearing tags 10 can be synchronized, so that the target physiological signals detected by multiple wearing tags 10 are synchronized in time. The change curve of time can also detect the change curve of body temperature with time. The function of the independent synchronization counter 12 is that the time values corresponding to the heart rate and body temperature are synchronized, that is, the time corresponding to the information collected by multiple different wearing tags are synchronous.

The control terminal 30 is wirelessly connected to the wearing tag 10 .

It can be understood that the wearing tag 10 and the control terminal 30 are not connected by wires, but are connected by wireless communication. For example, wireless communication connection can be realized through Bluetooth, WIFI, 4G, 5G or radio frequency. Redundant lines can be removed, and when the wearing tag 10 is attached to the living body, the movement of the living body will not be restricted too much.

The control terminal 30 may have a display screen 34 , which may display the target physiological signal collected by the wearing tag 10 on the display screen 34 , and the user can observe the real-time changes of the target physiological signal on the display screen 34 .

The control terminal 30 has a rest position 31 for placing the wearing tag 10 .

The resting position 31 can be groove-shaped, the wearing tag 10 can be placed in the resting position 31, and the resting position 31 can have a clamping mechanism, when the wearing tag 10 is placed in the resting position 31, it is clamped by the clamping mechanism, so that the wearing tag 10 is not easy to fall off from the resting position 31.

The control terminal 30 is configured to send a reset synchronization signal to the independent synchronization counters 12 of the at least two wearing tags 10 when the at least two wearing tags 10 are placed in the rest position 31 .

It can be understood that when multiple wearing tags 10 are placed in the resting position 31, the control terminal 30 can be electrically connected to the wearing tags 10, and the control terminal 30 can send a reset synchronization signal to the independent synchronization counter 12 of the wearing tags 10, that is, That is to say, when multiple wearing tags 10 are placed in the resting position 31, the independent synchronization counters 12 of the multiple wearing tags 10 are all cleared, and the independent synchronization counters 12 of the multiple wearing tags 10 start to count synchronously. The synchronization count refers to how many The independent synchronization counters 12 in each wearing tag 10 start to work on the same frequency.

In addition, there are some wireless monitoring devices for biological information, but these devices can only monitor physiological information in a certain area, and cannot monitor the physiological information of living organisms all over the body at the same time. If wireless monitoring is required in other parts of the body, it is often necessary to use cables to connect the sensors 15 worn at other locations to the worn host device. This is mainly to ensure the simultaneity of information collection. The host can simultaneously record the physiological information of each position through the internal wired connection and the control circuit under the same clock. Therefore, when an organism uses these wireless devices, in addition to wearing a small host, wired connections are also required in many parts of the body. The user experience is poor, and the device is more susceptible to the movement of the organism and the impact of the external environment.

Compared with the scheme in which the wearing tag 10 and the control terminal 30 are wiredly connected, the wireless communication connection scheme is prone to the phenomenon that the target physiological signals collected by different wearing tags 10 are not synchronized. Even by modifying the wireless transmission protocol or adding a complex time synchronization algorithm, it is difficult to ensure good synchronization and reliability between the various wearing tags.

In the present invention, an independent synchronization counter 12 is set in the wearing tag 10, and the control terminal 30 is set to send a reset synchronization to the independent synchronization counters 12 of at least two wearing tags 10 when at least two wearing tags 10 are placed in the rest position 31.
