In other words, each biosignal measuring apparatus uses a non-protocolized transmission protocol. When transmitting biometric information to an external device, a problem is that each biosignal measuring apparatus needs to make a program for each biosignal measuring device separately. In the future, it is necessary to collect a large amount of resources to generate a hospital information system or a personal health summary.

Hereinafter, with reference to the accompanying drawings will be described in detail.

1 is a block diagram illustrating a biosignal measuring apparatus according to an exemplary embodiment. Referring to FIG. 1, the biosignal measuring apparatus 100 includes a sensor 110, a signal processor 120, a protocol converter 130, and an interface 140.

The biosignal measuring apparatus 100 may be implemented as various devices for measuring various biosignals related to health, such as blood pressure, blood sugar, weight, electrocardiogram, exercise amount, respiration, and temperature. For example, the blood pressure measurement device may be used to measure blood pressure, the blood sugar measurement device to measure blood sugar, the weight scale to measure weight, and the electrocardiogram measurement device to measure electrocardiogram. Hereinafter, for convenience of description, it is assumed that the biosignal measuring apparatus 100 according to an embodiment of the present invention is an electrocardiogram measuring apparatus. Accordingly, the biosignal is an ECG signal. Electrocardiogram refers to recording the electrical signal of the heart through an electrode attached to the skin.

The sensor 110 is attached to the mother and senses a biological signal.

The sensor 110 may be implemented as an electrode unit attached to the skin in order to sense the biosignal, and the electrode unit may include two electrodes. In addition, the sensor 110 may be attached to various parts of the body. In addition, the sensor 110 may transmit the sensed biosignal to the signal processor 120.

In FIG. 1, only one sensor 110 has been described, but a plurality of sensors 110 may be provided.

The signal processor 120 may include an amplifier and a filter to perform a preprocessing step for amplifying a biosignal detected by the sensor 110 and removing noise.

In addition, the signal processor 120 may separate the maternal biosignal and the fetal biosignal by processing the preprocessed biosignal.

Here, the signal processor 120 may detect a signal section having a value greater than or equal to a threshold as a mother biosignal and detect a signal section having a value less than the threshold as a fetal biosignal by comparing the magnitude of the biosignal with a preset threshold. have.

In addition, the signal processor 120 compares the previously stored reference biosignal with the biosignal, detects a signal section matching the reference biosignal as a maternal biosignal, and detects a signal section that does not match the reference biosignal as a fetal biosignal. can do.

Hereinafter, a method of separating the mother biosignal and the fetal biosignal from the biosignal will be described in detail with reference to FIG. 2.

2 is a diagram illustrating a method of separating a maternal biosignal and a fetal biosignal from a biosignal according to an embodiment of the present invention. Referring to FIG. 2, the biological signal sensed from the mother has a complicated shape due to the mother's biological signal and random noise. Here, the main peaks appearing periodically are maternal bio signals due to maternal cardiac activity, and peaks with relatively smaller and faster periods are fetal bio signals due to fetal cardiac activity.

First, the signal processor 120 may perform a preprocessing step for amplifying a biological signal sensed from a mother and removing noise. The signal processor 120 may preset a threshold value that is a critical biosignal size capable of separating the maternal biosignal and the fetal biosignal by using a signal magnitude difference between the maternal biosignal and the fetal biosignal. The signal processor 120 detects a signal section having a value greater than or equal to a threshold as a mother biosignal and detects a signal section having a value below the threshold as a fetal biosignal by comparing a preset threshold with a biosignal sensed from the mother. can do. Accordingly, the signal processor 120 may separate the mother biosignal and the fetal biosignal.

In addition, the signal processor 120 may pre-store a reference biosignal capable of separating the mother biosignal and the fetal biosignal using shapes of the mother biosignal and the fetal biosignal. That is, referring to FIG. 2, the mother biosignal has a shape having a main peak appearing periodically, and the fetal biosignal has a shape having a relatively small and faster cycle, and thus the signal processor 120 is related to the mother biosignal. At least one of the shape and the shape related to the fetal biosignal may be previously stored. In addition, the signal processor 120 may store the mother biosignal shape or the fetal biosignal shape as a reference biosignal. If the signal processor 120 pre-stores the shape of the mother biosignal as the reference biosignal, the preprocessed reference biosignal is compared with the biosignal sensed from the mother, and a signal section matching the reference biosignal is converted into the mother biosignal. The signal section that is not matched with the reference biosignal may be detected as the fetal biosignal.

If the signal processor 120 pre-stores the shape of the fetal biosignal as a reference biosignal, the preprocessed reference biosignal and the biosignal sensed from the mother are compared, and a signal section matching the reference biosignal is a fetal biosignal. The signal section that is not matched with the reference biosignal may be detected as the mother biosignal.

In this case, in order to determine whether to match, a correlation signal may be determined to match a biosignal having a high similarity, and the biosignal having a low similarity may be determined to be mismatched.

As described above, by separating the mother and fetal biosignal from the biological signal sensed from the mother, it is possible to analyze the state of the mother's and fetal heart activity, respectively, so that monitoring of the mother's and fetal health status You can do that.

In addition, the signal processor 120 may include an analog-digital converter (ADC), and may convert the separated maternal and fetal bio signals into digital signals. The biosignal converted into a digital signal may be transmitted to the protocol converter 130.

The protocol converter 130 converts at least one of the maternal biosignal and the fetal biosignal into a signal format according to a predetermined standard protocol, respectively.

In more detail, the protocol conversion unit 130 may convert at least one of the mother biosignal and the fetal biosignal into a signal format having a grammar and a size defined by a standard protocol, respectively. Here, the standard protocol may be IEEE 11073. Hereinafter, the protocol converter 130 will be described in detail with reference to FIGS. 3 to 4.

3 is a block diagram specifically illustrating a protocol conversion unit according to an embodiment of the present invention. Referring to FIG. 3, the protocol converter 130 includes a standard protocol mapping unit 131 and an adapter 132. The standard protocol mapping unit 131 maps the non-standard protocol and the standard protocol supported by the biometric apparatus 100 and generates a script based on the mapping result. The generated script is sent to the adapter 132. The adapter 132 interprets the transmitted script and converts the non-standard protocol signal including at least one of the maternal and fetal bio-signals into a standard protocol signal.

The standard protocol mapping unit 131 includes a protocol analyzer 131-1, a mapping unit 131-2, and a script generation unit 131-3. The adapter 132 also includes a script interpreter 132-1 and a standard protocol converter 132-2.

The protocol analyzer 131-1 analyzes a protocol supported by the biosignal measuring apparatus 100. In this case, the protocol analyzer 131-1 analyzes whether the protocol supported by the biosignal measuring apparatus 100 is a nonstandard protocol or a standard protocol. If the protocol supported by the biosignal measuring apparatus 100 is a non-standard protocol, the protocol analyzer 131-1 transmits the analyzed information to the mapping unit 131-2. The mapping unit 131-2 generates mapping information by performing a mapping operation to convert the biosignal converted into a digital signal by the signal processing unit 120 of the biosignal measuring apparatus 100 into a standard protocol. The script generation unit 131-3 generates a script for converting a biosignal converted into a digital signal into a standard protocol based on the generated mapping information. The generated script may be as shown in FIG. 4. However, the script shown in FIG. 4 is merely an example, and other types of scripts may be possible. When the script is generated, the script generator 131-3 transmits the generated script to the script interpreter 132-1 of the adapter 132.

The script interpreter 132-1 converts the biosignal converted from the signal processor 120 of the biosignal measuring apparatus 100 into a digital signal by the standard protocol converter 132-2 of the adapter 132 into a standard protocol. Parse the transmitted script so that it can When the script interpreter 132-1 interprets the script, the standard protocol converter 132-2 converts the digital signal including the mother or fetal biosignal into a standard protocol signal based on the analysis result.

As described above, by converting the biological signal measured also in the biometric device 100 to a standard protocol, compatibility problems between devices can be solved.

In addition, when transmitting the biosignal from the biosignal measuring apparatus 100 used in the ubiquitous healthcare environment to an external device (for example, a ubiquitous healthcare system server), the transmission signal is used as a standard protocol for each biosignal measuring apparatus. When transmitting biometric information to an external device, it is possible to solve the problem that all programs for receiving information must be separately produced for each biosignal measuring device, thereby increasing resource efficiency.

The biosignal measuring apparatus 100 may further include a user interface unit (not shown). In more detail, a UI window for receiving a selection of a target signal to be converted into a signal format according to a standard from a mother biosignal and a fetal biosignal may be displayed through a user interface unit (not shown). In this case, the protocol converter 130 may convert the selected target signal into a signal format having a grammar and size prescribed by the standard. Hereinafter, the UI window will be described in detail with reference to FIG. 5.
