As another embodiment, the wearing member 100-3 may be a necklace-type member that a user can wear, or a member in the form of a headband, a helmet, or a band worn on the user's head. However, for convenience of explanation, the following description will be focused on an embodiment in which the wearing member 100 is a band-shaped member (eg, 100 in FIG. 1 ) formed to be worn on the user's arm.

The first sensor 110 is disposed on the wearing member 100 , and may detect a biosignal of the user P. As an embodiment, the first sensor 110 may detect the body temperature of the user P and generate a first detection signal S1 based on the sensed body temperature value. The first sensor 110 may provide the generated first detection signal S1 to the position detection unit 20 or the intermediate processor 30 . In this case, the first detection signal S1 may include information on the time the corresponding body temperature was measured, whereby the time at which the corresponding body temperature was measured may be detected.

The first sensor 110 may measure the body temperature of the user P in real time. Accordingly, the first sensor 110 may detect a change in body temperature of the user P in real time over time. Specifically, the first sensor 110 measures the body temperature of the user P every predetermined unit time, and accordingly, the change in body temperature of the user P according to the passage of time can be detected.

The second sensor 120 is disposed on the wearing member 100 and may detect a biosignal of the user P different from the biosignal detected by the first sensor 110 . As an embodiment, the second sensor 120 may detect the heart rate of the user P and generate a second detection signal S2 based on the detected heart rate. The second sensor 120 may provide the generated second detection signal S2 to the position detection unit 20 or the intermediate processor 30 . In this case, the second detection signal S2 may include information on the time at which the corresponding heart rate was measured, whereby the time at which the corresponding heart rate was measured may be detected.

The second sensor 120 may measure the heart rate of the user P in real time. Specifically, the second sensor 120 may measure the heart rate of the user P in a predetermined time unit. As an example, the second sensor 120 measures the heart rate of the user P for the first minute after setting 1 minute as the unit time, and then repeats measuring the heart rate of the user P again for 1 minute In this way, the heart rate of the user P may be measured. In this case, the second sensor 120 may measure the change in the heart rate of the user P for a unit time in real time, and thus may detect the change in the heart rate of the user P according to the passage of time.

As another embodiment, the second sensor 120 may be worn on the body of the user P, but may be disposed on a separate wearing member (hereinafter, additional wearing member) to be worn from the above-described wearing member 100 . Specifically, the second sensor 120 may be disposed on an additional wearing member (eg, 100-2 of FIG. 1 ) that can be worn on the wrist of the user P. In this case, the second sensor 120 may be disposed on the wrist of the user P by the additional wearing member 100 - 2 to detect the pulse rate (or heart rate) of the user P. The second sensor 120 may generate a second detection signal S2 based on the sensed pulse rate and provide it to the position detection unit 20 or the intermediate processor 30 . Other specific features may be the same as or similar to the embodiment in which the second sensor 120 is disposed on the wearing member 100 .

The third sensor 130 may provide the generated third detection signal S3 to the position detection unit 20 or the intermediate processor 30 . In this case, the third detection signal S3 may include time information at which the corresponding motion is sensed, and thereby, the time at which the corresponding motion is sensed may be detected.

Meanwhile, when the plurality of users P respectively wear the wearable device 10 , each wearable device 10 may generate a unique identification signal. By such a unique identification signal, the determination unit 40, which will be described later, may distinguish and specify who the user P wearing each wearable device 10 is.

The position sensing unit 20 may wirelessly communicate with the wearable device 10 to detect the position of the user P. Specifically, the position sensing unit 20 may receive the third sensing signal S3 from the third sensor 130 and detect the position of the user P based thereon. In this case, the position detecting unit 20 may set a predetermined detection range (hereinafter, referred to as a preset range), and may detect the position or movement of the user P within this preset range. As an example, the location detecting unit 20 may be a beacon device for detecting the location of the user P using wireless communication with the third sensor 130 , and as another example, the location detecting unit 20 . may detect the location of the user P using the GPS method. As another example, the third sensor 130 may detect the location of the user P using both the beacon device and the GPS.

As an embodiment, when the user P comes within a preset range, the location detecting unit 20 may detect this and generate an entrance signal S3a and transmit it to the intermediate processor 30 . As another embodiment, when the position detecting unit 20 continues to position the user P within a preset range (for example, if the user P moves only within a preset range or stops within a preset range), By detecting this, a position maintenance signal S3b may be generated and transmitted to the intermediate processor 30 . And, as another embodiment, when the user P goes out of a preset range, the position detecting unit 20 may detect this and generate an exit signal S3c and transmit it to the intermediate processor 30 .

At least one position sensing unit 20 may be provided. As an embodiment, a plurality of position sensing units 20 may be provided. In this case, the plurality of position sensing units 20 may be disposed in different places spaced apart from each other. In this case, the plurality of position sensing units 20 detects that the user P deviates from a place or a preset range in which any one of the plurality of position sensing units 20 is disposed, and after that, the user P detects a plurality of The movement path of the user P may be detected by detecting that the other one of the position sensing units 20 enters a place where the dog is disposed or a preset range. A detailed description thereof will be provided later.

As described above, the wearable device 10 and the position sensing unit 20 may transmit the collected information and a signal including the collected information to the intermediate processor 30 using, for example, a Private LoRa Network. there is.

The intermediate processor 30 may receive and collect the biosignal and/or motion signal of the user P from the wearable device 10 , and then transmit it to the outside. Here, the intermediate processor 30 may refer to, for example, a data processing device embedded in hardware having a physically structured circuit to perform a function expressed as a code or an instruction included in a program.

The intermediate processor 30 receives the first detection signal S1 from the first sensor 110 , receives the second detection signal S2 from the second sensor 120 , and receives the second detection signal S2 from the third sensor 130 . 3 The detection signal S3 may be transmitted. In this case, the intermediate processor 30 may include a wearing signal collecting unit 31 , a state signal collecting unit 32 , and a position signal collecting unit 33 .

The wearing signal collecting unit 31 receives the third detection signal S3, and collects the acceleration information and/or angular velocity information of the user P included in the third detection signal S3, and the wearable device 10 It is possible to generate a wearing signal (S31) for determining whether the state worn by the user (P). The wearing signal collecting unit 32 may transmit the generated wearing signal S31 to the determining unit 40 .

The state signal collecting unit 32 collects the first detection signal S1 and the second detection signal S2 to generate the state signal S12 of the user P, and determines the state signal S12 by the determination unit ( 40) can be transferred.

The position signal collection unit 33 collects the entry signal S3a, the position maintenance signal S3b, and the exit signal S3c generated by the third sensor 130 to generate the user's position signal S33, The user's location signal S32 may be transmitted to the determination unit 40 .

The determination unit 40 determines whether the user P wears the wearable device 10 or the infection state based on the signal received from the wearable device 10 , the intermediate processor 30 or the location detection unit 20 . can In addition, the determination unit 40 may track the movement path of the user P determined to be infected based on the signal. The determination unit 40 is implemented in the form of, for example, a circuit board mounted on a control computer of the monitoring system 1, a computer chip mounted on the circuit board, software embedded in a computer chip or embedded in a control computer, etc. can be

At this time, the determination unit 40 is provided with a first detection signal (S1), a state signal (S12), a wearing signal (S31), and a position signal (S32), noise removal and noise through a signal quality amplifier (not shown) can be removed and the quality of the signal can be amplified. Accordingly, the determination unit 40 can reduce the error in determining the infection state of the user P. In another embodiment, noise removal and signal quality amplification may be performed in the intermediate processor 30 . In this case, the intermediate processor 30 removes noise from the first detection signal S1 , the second detection signal S2 , and the third detection signal S3 received from the wearable device 10 or the position detection unit 20 . can be removed and the quality of the signal can be amplified.

The determination unit 40 receives the wearing signal S31 from the position sensing unit 20 (or from the wearing signal collecting unit 32), and determines whether the wearable device 10 is in a state worn by the user P. can judge

Specifically, when the determination unit 40 determines that the wearable device 10 has moved for a predetermined time or more based on the received wearing signal S31, the user P wears the wearable device 10 can be judged to be in progress. On the other hand, if the determination unit 40 detects the presence of the wearable device 10 in a specific place, but maintains a stationary state without movement for a predetermined time, the wearable device 10 is worn by the user P It is not a state that has been completed, and it can be determined that the state is separated from the user P.

As such, by determining whether the wearable device 10 is worn by the user P in real time, using the unique identification signal of each wearable device 10, it is possible to determine whether each user P wears the wearable device 10 there is. In addition, when it is determined that the specific wearable device 10 is separated from the user P, loss of the wearable device 10 can be prevented by notifying the corresponding user P. Accordingly, all users P can manage to keep wearing the wearable device 10 continuously, and as a result, the detection of the user P who is in an infected state due to not wearing the wearable device 10 is omitted. it can be prevented

The determination unit 40 may determine whether the user P is infected based on at least one of the first detection signal S1 and the second detection signal S2 received from the intermediate processor 30 .

As an embodiment, the determination unit 40 may receive the first detection signal S1 from the wearable device 10 or the intermediate processor 30 to determine the infection state of the user P. Specifically, the determination unit 40 may set a reference value (hereinafter, referred to as a preset reference value) serving as a criterion for determining whether the body temperature of the user P is abnormal. In this case, the determination unit 40 may determine that the user is infected when the detected body temperature of the user P is equal to or greater than a preset reference value.

At least one preset reference value may be provided. As an embodiment, a plurality of preset reference values may be provided. Here, the number of preset reference values is not limited, but for convenience of description, an embodiment in which two preset reference values including a first reference value and a second reference value are provided will be mainly described.

The first reference value and the second reference value may be different from each other. As an embodiment, the second reference value may be greater than the first reference value. In this case, the determination unit 40 may determine that the user P is in a suspected infection state when the detected body temperature of the user P is equal to or greater than the first reference value, and when the body temperature of the user P is equal to or greater than the second reference value , it can be determined that the user P is in an infected state.

As described above, the infection status determination criteria of the user P can be subdivided by using the plurality of reference values, and the infection status of the user P can be more precisely determined based on the subdivided determination criteria. In addition, by including a low reference value, it is possible to initially detect and isolate the user P in a suspected infection state, thereby preventing the spread of infection at an early stage.

As another embodiment, the determination unit 40 may receive the status signal S12 from the intermediate processor 30 (or from the status signal aggregator 32 ) to determine the infection status of the user P. In this case, the determination unit 40 may determine whether the user P is infected by synthesizing the information on the body temperature and heart rate of the user P included in the state signal S12 . Specifically, when the user P is infected with an infectious disease and the body temperature rises, the heart rate of the user P may also rise accordingly. In this case, the determination unit 40 may determine whether the detected body temperature of the user P is equal to or greater than a preset reference value and whether the heart rate of the user P is equal to or greater than a normal heart rate. Meanwhile, that the determination unit 40 may include a plurality of reference values for determining the body temperature of the user P may be the same as or similar to that described above.

Specifically, when the body temperature of the user P exceeds the reference value and the heart rate of the user P exceeds the normal heart rate at the same time, the determination unit 40 may determine that the user P is infected. On the other hand, if it is detected that the heart rate exceeds the normal heart rate even though the body temperature of the user P is close to the reference value, it may be determined that the user P is in a suspected infection state. As such, the determination unit 40 may determine whether the user P is infected more precisely by determining not only the body temperature of the user P but also whether the heart rate is abnormal.

The determination unit 40 may receive the location signal S33 from the intermediate processor 30 (or from the location signal aggregator 33 ) to determine and track the location and movement path of the user P. In this case, the determination unit 40 may detect the location of the current user P in real time based on the location signal S33 . In addition, when the user P moves from a specific place to another place, the places to which the user P has moved may be detected in the order of time. In this case, the place to which the user P moves may be a place where the position sensing unit 20 is disposed.

Specifically, when the user P enters a specific place, the determination unit 40 detects the user P's entrance to the specific place based on the entrance signal S3a generated by the location detection unit 20. can Thereafter, when the user leaves the specific place, the determination unit 40 may detect the user's exit from the specific place based on the exit signal S3c generated by the location detecting unit 20 . In addition, the determination unit 40, when the user P continues to be located in the specific place, based on the position maintenance signal (S3b) generated by the position sensing unit 20, the user within the specific position The position of (P) can be detected. When the user P moves between a plurality of places, a specific method for the determination unit 40 to detect the location of the user P will be described later.

The determination unit 40 may control the notification unit 50 based on a result of determining whether the user P is infected with an infectious disease. In this case, when it is determined by the determination unit 40 that a certain user P is infected, the notification unit 50 may notify the outside of the occurrence of an infected person.

The notification unit 50 may notify the outside of the occurrence of an infected person or a suspected infection by using various methods. As an embodiment, the notification unit 50 may include a display unit (not shown) and a warning light (not shown). In this case, when an infected person or a suspected infection occurs, the notification unit 50 is controlled by the determination unit 40 to notify the manager of the monitoring system 1 through the display unit of the occurrence of an infected person or a suspected infection, at the same time or at the same time. By displaying a warning signal through a warning light at the workplace where an infected person or suspected infection occurred and a place adjacent thereto, it is possible to immediately notify the workers (or workers) working at the place. Additionally, the notification unit 50 may further include an acoustic warning unit. In this case, not only the visual warning by the above-described warning light, but also a more rapid response can be made by generating a warning sound through the acoustic warning unit to notify the outside of the occurrence of an infected person or a suspected infection. However, the present invention is not limited thereto, and the notification unit 50 may notify the occurrence of an infected person or a suspected infection to a manager and a worker using various other methods.

Specifically, the first position detecting unit 20-1 is disposed in the first workplace L1, the second position detecting unit 20-2 is disposed in the second workplace L2, and the third workplace L3 ), the third position sensing unit 20-3 may be disposed. In addition, the fourth position detecting unit 20 - 4 may be disposed in the fourth workplace L4 . In this case, the preset sensing range of each position sensing unit 20 may be the same as the size of the workplace in which each position sensing unit 20 is disposed.

The first user PA, the second user PB, and the third user PC may enter the work environment 2 through the access unit L0. In this case, the thermal imaging unit C may be disposed at the entrance L0. The thermal imaging unit (C) may take a thermal image of the worker or user (P) passing through the entrance (L0). Such a thermal image may include information about the body temperature of the user P. The thermal imaging unit C may be, for example, a thermal imaging camera capable of photographing a thermal image of a human body, such as a near-infrared camera or an infrared camera.

The thermal imaging unit C may transmit the captured thermal image to the determination unit 40 through the intermediate processor 30 or directly to the determination unit 40 . In this case, the determination unit 40 may primarily detect whether the user P passing through the entrance L0 is infected based on the received thermal image. Specifically, when the body temperature of the user P included in the video image is equal to or greater than the reference value as described above (eg, in the case of a PC in FIG. 3 ), the determination unit 40 returns to the workplace of the user P. You can control access. Accordingly, it is possible to prevent the entire working environment 2 from being closed by pre-controlling access to the workplace of the user P who is in an infected state or a suspected infection state.

Although the above-described working environment 2 has been mainly described with respect to a case in which one entrance L0 is provided, the present invention is not limited thereto, and a plurality of entrances L0 may be provided at different locations. . In this case, a thermal imaging unit C is installed in each entrance L0 to capture a thermal image of a worker or user P passing through each entrance L0.

As an embodiment, after the first user PA normally passes through the entrance L0, the first user PA may move from the first workplace L1, through the second workplace L2, to the fourth workplace L4. . In this case, the wearable device 10 worn by the first user PA (or the third sensor 130 ) sequentially performs the first position sensing unit 20 , the second position sensing unit 20 , and the third By communicating with the location detecting unit 20 , location information of the first user PA may be transmitted. The determination unit 40 receiving the location information may track and store the movement path of the first user PA.

As another embodiment, after the second user PB normally passes through the entrance L0, the second user PB may move from the third workplace L3, through the first workplace L1, to the second workplace L2. . In this case, the wearable device 10 worn by the second user PB (or the third sensor 130 ) sequentially performs the third position sensing unit 20 , the first position sensing unit 20 , and the second By communicating with the location sensing unit 20 , location information of the second user PB may be transmitted. The determination unit 40 receiving the location information may track and store the movement path of the second user PC.

As another embodiment, as described above, when the body temperature sensed by the thermal imaging unit C of the third user PC at the entrance L0 is equal to or greater than the reference value, the determination unit 40 determines the third user A warning may be given through the notification unit 50 to prevent the PC from passing through the access unit L0. Accordingly, it is possible to prevent an infected third user (PC) from entering the workplace.

4A shows an example of a change in body temperature according to the movement path of the first user PC. Referring to FIG. 4A , the movement path of the first user PC detected by the determination unit 40 passes through the entrance L0, and the first and second workplaces L1 and L2 ), it can be identified as being located in the fourth workplace (L4). In this case, the first user PA maintains a normal body temperature range while moving along the movement path, and accordingly, the determination unit 40 may determine that the first user PA is in a normal state. Accordingly, the determination unit 40 may control the notification unit 50 not to operate.

4(b) shows an example of a change in body temperature according to the movement path of the second user PB. Referring to FIG. 4(b) , the movement path of the second user PB detected by the determination unit 40 passes through the entrance L0, and the third work site L3 and the first work site L1 ), it can be identified as being located in the second workshop L2. In this case, the second user PB has a normal body temperature from the entrance L0 to the third workplace L3, but has risen to a body temperature higher than the reference value from the first workplace L1. By receiving the body temperature information of the second user P in the second workplace L2, it may be determined that the second user P is in an infected state or a suspected infection state.

In the case described above, the determination unit 40 may control the notification unit 50 to notify the outside of the user P in the infection state in the second workplace L2. Accordingly, it is possible to close the second workplace L2 and the workplaces located in the movement path of the second user P, and perform necessary measures for quarantine, and in this workplace, the second user P and the second user P By identifying and isolating users (P) who have been working together, it is possible to prevent the spread of infectious diseases.

Meanwhile, referring to FIG. 4(c) , the third user PC whose body temperature abnormality is detected by the thermal imaging unit C at the entrance L0 is not allowed to enter the workplace. It can be confirmed that body temperature and location are not detected in places other than (L0).

5 is a flowchart illustrating a method for a monitoring system to determine a user's infection status according to an embodiment of the present invention.

Referring to FIG. 5 , a monitoring method according to an embodiment of the present invention may be as follows.

First, a thermal image of the user P may be photographed through the thermal imaging unit C at the entrance L0 (S10). In this case, the determination unit 40 may determine whether the body temperature of the user P included in the thermal image is equal to or greater than a reference value (S11). When the body temperature of the user P is greater than or equal to the reference value, the user P (ie, the infected person) can control access to the workplace and take quarantine measures (S11-2). On the other hand, when the body temperature of the user P is less than the reference value (ie, normal body temperature), the user P may be allowed to enter the workplace.

Next, by the wearable device 10 and the position sensing unit 20, the biosignal and the position of the user P who entered the workplace may be sensed in real time (S20). Specifically, the body temperature of the user P may be detected by the first sensor 110 in real time, and the heart rate of the user P may be detected by the second sensor 120 in real time. These biosignals of the user P may be transmitted to the determination unit 40 through the intermediate processor 30 or may be directly transmitted to the determination unit 40 .

Next, the determination unit 40 may determine the infection state of the user P based on the received bio-signal (S30). Specifically, the determination unit 40 may determine the infection state of the user P by comparing whether the user P's body temperature is equal to or greater than a reference value and/or whether the user P's heart rate is a normal heart rate. . At this time, if the body temperature is higher than the reference value or the user P is not detected whose heart rate is not a normal heart rate, the user performs their respective tasks and at the same time the monitoring system 1 continues the infection status of the user P is monitored (S50).

Next, when the determination unit 40 determines that the user P is an infected person, the determination unit 40 may control the notification unit 50 to notify the outside of the infected person (S40). Specifically, the determination unit 40 determines the user ( When the body temperature of P) is equal to or greater than the reference value and/or when the heart rate of the user P is equal to or greater than the normal heart rate, it may be determined that the user P is an infected person. Accordingly, the determination unit 40 controls the notification unit 50 to notify the manager of the monitoring system 1 that an infected person has occurred, so that the manager can take measures to prevent the spread of the infectious disease.

Next, the determination unit 40 may determine the current location and movement path of the infected user (ie, the infected person), and then close the location and movement path ( S41 ). For example, if the infected person is currently performing work in the fourth workplace L4 after passing the first workplace L1 and the second workplace L2, the determination unit 40 determines the fourth workplace, which is the current location of the infected person. The workplace L4 and the first workplace L1 and the second workplace L2 passed by the infected person may be identified as the movement path of the infected person. Accordingly, it is possible to close the corresponding workplaces.

Next, the determination unit 40 may identify and quarantine other workers who have come into contact with the infected person based on the identified movement path of the infected person (S42). For example, if the infected person is currently performing work in the fourth workplace L4 after passing through the first workplace L1 and the second workplace L2 as described above, the determination unit 40 determines that the infected person is at each workplace You can figure out how long you've stayed, and you can figure out other workers who were in the same workplace at the same time. In this way, other workers who have come into contact with the infected person can be selected and quarantined.

Next, the manager of the monitoring system 1 may perform quarantine of the workplaces located within the movement path of the infected person after the quarantine of the infected person and the contact person and the closing of the workplace are completed. Thereby, the spread of an infectious disease can be quickly prevented, and appropriate measures can be taken for a patient with an infectious disease, thereby preventing worsening of symptoms of an infected person.

In each step of the monitoring method as described above, the specific features of the wearable device 10, the position detecting unit 20, the intermediate processor 30, and the determining unit 40 are the same as or similar to those described above. A description will be omitted.

As described above, the monitoring system 1 according to embodiments of the present invention detects the user P's biosignal in real time to determine the infection status, thereby enabling rapid situation recognition and response when an infected person occurs. In addition, by tracking the location and movement path of the user P in real time, when an infected person occurs, other workers who have come into contact with the infected person are identified and quarantined, and only workplaces located within the movement route of the infected person can be selected and closed. Accordingly, it is possible to prevent the spread of infectious diseases at an early stage and to minimize human and material damage caused by the occurrence of infectious diseases.

The description of the present invention described above is for illustration, and those of ordinary skill in the art to which the present invention pertains can understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention. will be.
