Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. 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 invention.
The physiological signal acquisition system and method of the present invention are described below with reference to fig. 1-6.
As shown in fig. 1 and 4, the present invention provides a physiological signal acquisition system including: at least two wearing tags 10 and a control terminal 30.
The number of the wearing tags 10 may be plural, the number of the wearing tags 10 may be 2 to 12, for example, 5, and the plural wearing tags 10 may be worn on a living body, which may be a human body, or other animal bodies, such as some domestic animals or pets.
The wearable tag 10 has acquisition means for acquiring a target physiological signal and a separate synchronous counter 12.
The wearable tag 10 may have an acquisition device that can be used to acquire a target physiological signal that is a physiological characteristic of the organism itself, such as body temperature, heart rate, blood oxygen concentration, and blood pressure.
The wearable tag 10 may have an attachment member that can be attached to a target site of a living being, such as the forehead or wrist, for monitoring body temperature, and can be attached to the chest for monitoring heart rate.
The independent synchronous counter 12 counts the number of pulses in a digital system to realize digital measurement, operation and control, the independent synchronous counter 12 can be used for giving a timestamp, the independent synchronous counter 12 is installed on each wearing tag 10, then the independent synchronous counters 12 of a plurality of wearing tags 10 can be synchronized, so that target physiological signals detected by the plurality of wearing tags 10 are synchronized in time, for example, the wearing tags 10 can detect a change curve of a heart rate along with time, and can also detect a change curve of a body temperature along with time, the independent synchronous counter 12 acts on the fact that time values corresponding to the heart rate and the body temperature are synchronized, namely, the time corresponding to information collected by a plurality of different wearing tags is synchronized.
The control terminal 30 is connected to the wearable tag 10 in wireless communication.
It can be understood that the wearing tag 10 and the control terminal 30 are not connected by a wire, but are connected by wireless communication, for example, the wireless communication can be realized by bluetooth, WIFI, 4G, 5G or radio frequency, and by the wireless communication, redundant lines can be eliminated, so that when the wearing tag 10 is attached to a living body, the activity of the living body is not limited too much.
The control terminal 30 may have a display 34, and the target physiological signal collected by wearing the tag 10 may be displayed on the display 34, and the user can observe real-time changes of the target physiological signal on the display 34.
The control terminal 30 has a rest position 31 for placing the wearing tag 10.
Put the position 31 and can be for the recess form, wear label 10 and can place and put position 31, put position 31 and can have a chucking mechanism, place when putting position 31 when wearing label 10, by the chucking mechanism chucking for it is difficult to follow and puts position 31 and drop to wear label 10.
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 at the rest position 31.
It can be understood that, when a plurality of wearing tags 10 are placed in the placement position 31, the control terminal 30 may be electrically connected to the wearing tags 10, and the control terminal 30 may send a reset synchronization signal to the independent synchronization counters 12 of the wearing tags 10, that is, when a plurality of wearing tags 10 are placed in the placement position 31, the plurality of independent synchronization counters 12 of the wearing tags 10 are all cleared, the plurality of independent synchronization counters 12 of the wearing tags 10 start synchronous counting, and synchronous counting refers to that the independent synchronization counters 12 in the plurality of wearing tags 10 start to work at the same frequency.
At present, most of conventional devices used clinically in hospitals or used for home assistance are wired devices, and professionals need to attach terminals such as electrodes or sensors to specific positions of organisms and connect the terminals to a detection host computer in a wired connection manner to acquire and process physiological information of the organisms. Such devices often require a plurality of cables to be tied around the body of the living being, which is inconvenient to use.
In addition, some biological information wireless monitoring devices exist at present, but these devices often can only monitor physiological information in a certain area, and cannot monitor physiological information of a biological body all over the body at the same time. If wireless monitoring is required elsewhere throughout the body, it is often necessary to connect the sensor 15 worn elsewhere to the host device worn by the user by cable. The information acquisition simultaneity is mainly required to be ensured, and the physiological information of each position can be recorded simultaneously through internal wired connection and a control circuit under the same clock in the host. Therefore, when the living body uses the wireless devices, the living body wears a small host, and a plurality of places of the whole body also need to be connected by wires, so that the user experience is poor, and the devices are more easily influenced by the movement of the living body and the external environment.
Compared with a scheme of wired connection between the wearing tag 10 and the control terminal 30, the scheme of wireless communication connection is prone to the phenomenon that target physiological signals acquired by different wearing tags 10 are not synchronous. Even by modifying the wireless transmission protocol or adding a complicated time synchronization algorithm, it is difficult to ensure good synchronization and reliability between the respective wearing tags.
In the invention, the independent synchronous counter 12 is arranged in the wearing tags 10, and the control terminal 30 is set to send the reset synchronous signal to the independent synchronous counters 12 of the at least two wearing tags 10 when the at least two wearing tags 10 are placed on the placing position 31, so that the control terminal 30 can reset the plurality of wearing tags 10, and the plurality of wearing tags 10 can realize the time synchronization and avoid the dislocation in the process of acquiring the target physiological signal.
According to the physiological signal acquisition system provided by the invention, the wearing label 10 is wirelessly connected with the control terminal 30, and the independent synchronous counter 12 is arranged in the wearing label 10, so that the limitation of the physiological signal acquisition process on the biological activity can be reduced, the synchronization of the acquisition time is realized, and the acquisition efficiency and the accuracy are improved.
As shown in fig. 2, in some embodiments, the wearable tag 10 is provided with a first synchronization port 11, the control terminal 30 is provided with a second synchronization port 32, the second synchronization port 32 can be located at the placement position 31, the first synchronization port 11 and the second synchronization port 32 can be butted, and when the first synchronization port 11 and the second synchronization port 32 are butted, an electrical connection can be realized.
When at least two wearing tags 10 are placed on the placement position 31, the first synchronization port 11 is electrically connected with the second synchronization port 32, and the control terminal 30 sends reset synchronization signals to the at least two independent synchronization counters 12 wearing the tags 10 through the first synchronization port 11 and the second synchronization port 32.
It can be understood that, when a plurality of wearing tags 10 are placed in the placement position 31, the first synchronization ports 11 of the plurality of wearing tags 10 are electrically connected with the corresponding second synchronization ports 32, at this time, the control terminal 30 is electrically connected with the independent synchronization counters 12 of the wearing tags 10, the control terminal 30 can send reset synchronization signals to the independent synchronization counters 12, so that the plurality of wearing tags 10 can achieve time synchronization, and then when the plurality of wearing tags 10 leave the placement position 31 and are attached to a living body, the acquired target physiological signals are synchronized in time.

In the wireless acquisition mode, the control terminal 30 can acquire the target physiological signal in real time, so that the accuracy of acquiring the target physiological signal can be improved, and the signal loss phenomenon caused by long-time storage can be avoided.
When the wireless communication component sends the target physiological signal to the control terminal, the target physiological signal and the time stamp of the corresponding independent synchronous counter can be packaged and sent to the control terminal together.

The processor 13 is provided with a local operating mode.
The wearable tag 10 may also have a memory 25, and the memory 25 may be electrically connected to the processor 13.
In the local operation mode, when the acquisition device acquires the target physiological signal, the acquisition device stores the target physiological signal, which may be stored in the processor 13 or the memory 25, that is, the target physiological signal is not immediately transmitted to the control terminal 30.
When the wearing tag 10 is placed at the rest position 31, the stored target physiological signal is transmitted to the control terminal 30.

Both the processor 13 and the independent synchronous counter 12 are electrically connected to a power supply assembly 23.
