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

1 is an overall configuration diagram showing a health monitoring system using the RFID tag 100 according to the present invention. The RFID tag 100, which is stored in the case and has a band connected to both symmetrical ends of the case, is a type worn on a wrist such as a human wristband or a wristwatch. The tag 100 includes a thermal sensor, a pulse sensor, and a detector 150 that detects blood sugar to detect biometric information. The biometric information detected by the tag 100 displays the biometric information detected through the display unit 140 provided on one surface of the case. The reader 300 identifies and processes biometric information stored in the tag 100, and the server 400 stores biometric information read from the tag 100 in the database 410 and analyzes and manages the stored biometric information.

FIG. 2 is a diagram illustrating a schematic shape of the tag 100 illustrated in FIG. 1. Bands 51 may be connected to both symmetric ends of the case 50 that accommodates the tag 100 and may be attached to the wrist. The display unit 140 is provided on one surface of the tag 100 and displays the biometric information obtained by the sensing unit 150 embedded in the PCB substrate in the tag 100. The antenna 111 is arranged along the edge of the case 50.

Detailed description of the shape of the antenna 111 will be described with reference to FIG. 7 together.

FIG. 7 is a diagram illustrating an example in which the antenna 111 of FIG. 2 is accommodated in a case 50.

The antenna 111 is mounted in a dipole form or a loop form. The antenna 111 is formed by winding a winding several times in the groove 102 inside the side of the case 50. Therefore, when the reader 300 recognizes the tag 100, information can be detected due to the winding of the antenna 111 wound on one side.

However, if the case 50 is made of a metal material, since it interferes with the wireless communication between the antenna 111 and the reader 300, the case 50 should be made of a non-metal material. For example, it is a material of a nonmetal such as plastic, rubber, and glass.

FIG. 8 shows an example in which a dipole type antenna 111 is formed on both sides of a band 51.

The antenna 111 is placed over both sides of the band 51 starting from the center of the case 50. Since the length of the antenna 111 can be as long as the length of the tag 50 and the band 51, it is suitable for the use of a low frequency band such as AM which requires the long antenna 111.

9 shows another example in which the antenna 111 of FIG. Dipole type is embedded on one side of the band 51 in a dipole form.

The antenna 111 is arranged starting from one side of the band 51, and occupies only a part of the band 51, so that the antenna 111 is suitable for a high frequency band, and the data rate is also processed quickly. In addition, when the band 51 is bent, the risk that the antenna 111 is broken is small.

FIG. 10 is a diagram illustrating another example in which the antenna 111 is mounted on the inner surface of the case 50 of the tag 100 in a dipole form.

The antenna 111 is mounted on the inner side of the case 50. Although it can be mounted on the outer circumferential surface, it can be broken according to the external environment, it is preferable to mount on the inner surface. In addition, since it is mounted on the inner surface of the case 50, the sense of stability is higher than that mounted on the band 51.

3 is a block diagram of the RFID tag 100 illustrated in FIG. 1. The RFID tag 100 includes a transceiver 110, a controller 120, a memory 130, a speaker 135, a display 140, a detector 150, a converter 160, and a power supply 170. Include.

The transceiver 110 includes an antenna 111 and modulates information stored as a digital signal in the memory 130 into a radio frequency (RF) 112 signal to transmit and receive with the reader 300.

The control unit 120 transmits and receives a transmission / reception unit 110, a memory 130, a speaker 135, a display unit 140, a detection unit 150, a conversion unit 160, and a power supply unit 170 performed by the tag 100. Control and manage its functions. In detail, the controller 120 operates the detector 150 at predetermined intervals in the memory 130. In addition, the controller 120 further includes a determination unit 121 and an alarm signal generator 122.

The determination unit 121 determines whether the biometric information is included in the allowable range value from the biometric information obtained from the detector 150 and the allowable range value stored in the memory 130. In addition, when the biosignal value is not included in the allowable range value in the determination unit 121, the alarm signal generator 122 sounds an audio signal to the speaker 135 and displays a visual signal on the display unit 140.

The memory 130 allows to determine the state of biometric information such as user information (ID), heat, pulse, and blood sugar, which are unique numbers of each tag 100 registered in the server 400, with a predetermined reference value. Range, biometric information that is the heat, pulse, and blood glucose values obtained from the detection unit 150, and the sound source when the normal value determined by the determination unit 121 and the sound source when abnormal value is different from the normal value sound source Consists of a sound source file stored as a sound source.

The display unit 140 displays the obtained biometric information on the display unit 140 provided on one surface of the tag 100, such as "body temperature 37 ° C. [normal]", and the detector 150 detects heat, pulse, and blood sugar to be detected. According to the temperature sensor, pulse detector, blood sugar detector is divided into.

The converter 160 converts the information obtained by the detector 150 into a digital signal that can be stored in the memory 130.

The tag 100 is driven by a battery, and the power supply unit 170 constantly outputs the voltage of the battery.

4 is a flowchart illustrating a process of a health monitoring system using the RFID tag 100 according to the present invention. First, the tag 100 receives an initialization value from the reader 300.

Here, the initialization value includes user information (ID), medical history information, an allowable range value for determining the state of the biometric information, and a period value for operating the sensing unit 150 (S510).

The user information (ID) is a unique number for each tag 100 registered in the server 400, the medical history information is a history of the user, the cause of the disease, constitution, specific symptoms, progress of the disease, And information about the course of treatment.

The allowable range value for determining the state of the biometric information is a reference range value for determining respective values for heat, pulse, and blood sugar. For example, the allowable range for heat is set based on a normal value of 34 to 37 ° C based on the armpit. Therefore, if the temperature is 38 ~ 39 ℃ or more, it can be classified as a dangerous value when the heat generation is above 40 ℃.

Like the heat level, the pulse rate is set to 60 to 100 times per minute for adults. Similarly, in the case of blood sugar, if the fasting value is 80 to 110 mg / dl and the 2-hour postprandial value is 80 to 140 mg / dl, the normal value is set.The fasting value is 110 to 125 mg / dl and the 2-hour postprandial value is 140 to 180 mg / dl. In this case, if the limit value, fasting value exceeds 125mg / dl, 2 hours after meals exceeds 180mg / dl, hyperglycemia level can be measured at any time regardless of meal, and can be classified as diabetes when 200mg / dl or more.

The period value for operating the sensing unit 150 also depends on the setting. For example, blood sugar can be set every hour and every two hours. When blood sugar is measured before 7 am, the blood sugar is determined by detecting the blood sugar by applying a 2-hour postprandial value until 9 am, based on the fasting value. To increase the accuracy.

Therefore, the tag 100 stores the ID, the allowable range value, and the period value transmitted from the reader 300 in the memory 130 (S520). The controller 120 operates the detector 150 at every cycle stored in the memory 130 (S530). The sensor 150 obtains the biometric information (S540), and the obtained biometric information passes through the conversion unit 160 that converts the biometric information into digital that can be stored in the memory 130.

The biometric information digitally converted is stored in the memory 130 (S550), and the determination unit 121 compares the biometric information acquired by the detector 150 with the allowable range value stored in the memory 130 ( S560), it is determined whether the normal state and the dangerous state of the biometric information value (S570). For example, if the body temperature is detected at 37 ° C. in the sensing unit 150 for detecting body temperature, the blood sugar is detected as normal, and if the blood sugar detected in the fasting unit is detected at 130 mg / dl, the blood sugar is determined as high blood sugar. It is.

Therefore, when the biometric information determined by the determination unit 121 includes the allowable range stored in the memory 130 as in the case of body temperature, the display unit 140 is immediately detected on the surface of the case 50 of the tag 100. The biometric information is displayed (S590). The biometric information may be displayed in various ways. For example, when the sensing unit 150 detects the biometric information at a predetermined cycle, the sound of 'beep' at the speaker 135 of the tag 100 is displayed. While exporting the user to check the biometric information of the display unit 140. When the body temperature is sensed at 37 ° C. as in the case of the above body temperature, the display unit 140 may display “body temperature 37 ° C. [normal]” in this manner. Therefore, when the pulse rate detection unit 150 detects 70 times per minute, the display unit 140 displays “70 pulses / minute [normal]”. Similarly, when blood sugar is detected at 100 mg / dl by the detection unit 150 at 6 am, the display unit 140 may display “blood sugar 100 mg / dl [normal]”.

However, if the blood sugar is detected as 130mg / dl as in the case of the above blood sugar, high blood sugar is out of the normal level of blood sugar, follow-up measures are necessary. The tag 100 transmits the ID value and the biometric value previously stored in the memory 130 from the RF transceiver 110 to the reader 300 (S580), and the reader 300 sends this to the server 400. Relay. In addition, the alarm signal generator 122 transmits an alarm signal (S580). Therefore, the speaker 135 emits a sound different from the sound generated when the normal value is set as '삑 삑삑', and displays the display unit 140 as "blood sugar 130mg / dl [high blood sugar]" (S590).

5 is a block diagram of a tag 200 according to an embodiment of the present invention. 5 is an embodiment of the RFID tag 200 for detecting the blood sugar mentioned in FIG. Some identical components shown in FIG. 5 are given the same reference numerals as in FIG. 3.

The transceiver 210 includes an antenna 211, and modulates information stored as a digital signal in the memory 230 into a radio frequency (RF) 212 signal to transmit and receive with the reader 300.

The control unit 220 of the transmitting and receiving unit 210, the memory 230, the speaker 235, the display unit 240, the blood sugar detector 250, the conversion unit 260, the power supply unit 270 performed by the tag 200 Control and manage functions. In detail, the controller 220 operates the blood sugar detector 252 at predetermined intervals in the memory 230. In addition, the controller 220 may further include a determiner 221, an alarm signal generator 222, and a needle controller 223.

The determination unit 221 determines whether the biometric information is included in the allowable range value from the biometric information obtained from the blood sugar detecting unit 252 and the allowable range value stored in the memory 230. In addition, when the biosignal value is not included in the allowable range value in the determination unit 221, the alarm signal generator 222 sounds an audio signal to the speaker 235 and displays a visual signal on the display unit 240. The needle controller 223 controls the needle driving to extract blood from the user.

In the memory 230, user information (ID), which is a unique number of each tag 200 registered in the server 400, for example, a fasting value of 80 to 110 mg / dl, and a 2-hour value of 80 to 140 mg / dl is the allowable range for determining the normal value as a reference, the biological information which is the blood sugar level such as 100 mg / dl obtained from the blood sugar detecting unit 252, and the sound source ringing when the normal value determined by the determining unit 221 is determined. In case of abnormal value, it is composed of sound source files stored as different sound sources than normal value sound sources.

The display unit 240 displays the obtained biometric information on one surface of the tag 200 such as "blood sugar 100 mg / dl [normal]".

In an embodiment, the tag 200 includes a needle (not shown) for extracting blood in contact with the wrist, and the blood sugar detector 250 further includes a needle driver 251 and a blood sugar detector 252. The needle driver 251 operates a motor (not shown) for driving the needle by the needle controller 223. The blood detected by the needle is detected through the blood sugar detecting unit 252, and the detected signal is converted into a digital signal that can be stored in the memory 230 by the converter 260.

The tag 200 is driven by a battery, and the power supply unit 270 constantly outputs the voltage of the battery.

6 is a block diagram of the server 400 shown in FIG. 1. The server 400 transmits the ID, which is a unique number for each tag 100, received from the tag 100 to the server 400 through the reader 300, and the biometric information to the database (DB) 410. Save it. The ID management module 420, the allowable range management module 430 for each ID, and the analysis function module 440 which checks and analyzes biometric information for each time zone based on the stored biometric information are operated.

Therefore, in the case of a hospital in which the health monitoring system using the RFID tag 100 is introduced, the tag 100 is attached to the wrist of the patient, and the biometric information of the patient is obtained at regular intervals. The permissible range of biomarkers for the patient's pulse is set at 60 to 100 times per minute to normal values. Therefore, if the pulse value obtained from the patient is 120 times per minute, the deviation from the normal value, the tag 100 transmits the ID, and pulse rate value to the reader 300. The server 400 receives the ID, medical history information, and pulse rate from the reader 300, and receives the position of the reader 300 that recognizes the tag 100 of the patient, so that the hospital quickly and accurately diagnoses the patient.
