In this process, the thickness of the lines or the size of components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, terms to be described later are terms defined in consideration of functions in the present invention and may vary according to the intention or custom of users or operators. Therefore, definitions of these terms should be made based on the contents throughout the present specification.

1 is a block diagram showing the configuration of a system for calculating patient location information using a beacon arrangement pattern according to an embodiment of the present invention, and FIGS. 2 to 4 illustrate a beacon arrangement pattern according to an embodiment of the present invention. It is an exemplary diagram for explaining a beacon arrangement pattern and grouping in the used patient location information calculation system.

As shown in FIG. 1, a system for calculating patient location information using a beacon arrangement pattern according to an embodiment of the present invention may include a server 10 and a beacon 20.

The user device 1 is a device that a user (patient) can move with, and may be, for example, a wearable device that a patient can wear. Such a wearable device may be composed of a memory, a radio frequency identification (RFID) and/or near field communication (NFC) module, a processor unit, a Bluetooth module, a 3-axis accelerometer and/or a compass, a battery, and a display.

Such a wearable device may be a smart watch in the form of a wrist watch, but is not limited thereto. For example, an accessory device in the form of a ring or necklace other than a watch, a clothing integrated into fabric ( Clothing) devices, body-attached devices such as skin patches, and bio-implemented devices that implant electronic devices in the body may be any type of device.

Also, the wearable device may output information including a display, a speaker, a vibration device, etc. or provide an alarm to a wearer (patient), and may communicate with the beacon 20 through a Bluetooth module.

In addition, the wearable device may further include an input device capable of receiving a command from a wearer (patient). For example, as such an input device, a touch screen or a voice recognition unit including a microphone may be employed. Alternatively, a button for a patient to call a medical staff may be included in the wearable device as such an input device, and the call button may be divided into an emergency button and a button for general situations.

However, since the user device is not limited to the above-described configuration, a smartphone or the like may be employed as the user device.

The beacon 20 may be installed in a medical institution and may communicate with the user device 1. In addition, the beacon 20 is connected to the server 10 by wired or wirelessly, and transmits connection information with the user device 1 (eg, identification information of the user device 1, received signal strength (RSSI)) to the server 10. I can.

The space of the medical institution in which the beacon 20 is installed may be physically or logically divided, and a plurality of beacons 20 may be arranged in a specific arrangement pattern for each divided area.

Whereas the existing methods collectively install beacons in the passage of a building structure, in the present invention, a specific space is divided into several areas so that they do not interfere with each other, and beacons are arranged so that the beacon arrangement patterns in the adjacent areas are different. It reduces the interference between beacons and accurately divides the area so that the location information can be calculated.

The arrangement pattern of the beacon 20 may be a rectangle, a rhombus, a double type, or a combination thereof, and by forming a different arrangement pattern of the beacon 20 for each floor of a building, floor division may be possible.

The server 10 receives and collects the received signal strength between the user device 1 and the beacon 20 from the beacon 20 while the user device 1 passes through a specific area. The server 10 may determine the change in the received signal strength when the user device 1 passes through the area based on the received signal strength collected in this way, and thereby calculate the location information of the user device 1.

That is, according to the arrangement pattern of the beacon 20, the received signal strength changes in a specific pattern while the user device 1 passes the corresponding area, so the server 10 uses the received signal strength to increase the received signal strength. Similar beacons may be grouped, and location information of the user device may be calculated based on the grouping pattern.

For example, as shown in Fig. 2, when the beacons 20 are arranged in a rectangular arrangement pattern in a specific area, when the patient is located at the U1 position, the received signal strength of the 3 left and 2 right beacons Since the values of are similar, the grouping pattern of beacons appears in the form of two groups (Group(A) = B1, B2, B3, Group(B) = B4, B5).

In addition, when the patient is located in the U2 position, since the values of the received signal strength of the two left and three right beacons are similar, three beacons (B3, B4, B5) and two beacons (B1, B2) are grouped respectively. Beacons are grouped in a form.

The server 10 can determine the location of the patient (ie, the user device 1) through this grouping pattern when it is located at a specific point in the corresponding area.

3 shows a double-type beacon arrangement pattern. When the user device 1 is located at the entry point (U1), 1/3 point (U2), 2/3 point (U3), and exit point (U4) of the area, the beacon grouping pattern is in a specific form. Will appear.

In other words, at the entry point, beacon groups are grouped into 4 groups, 1-5, and at the point 1/3, beacon groups are grouped into 4 groups (Group(A)=B2, Group(B)=B1,B3, Group(C)). )=B4, Group(D)=B5).

In addition, at the 2/3 point, the beacon group is grouped into 4 groups (Group(A)=B4, Group(B)=B3,B5, Group(C)=B2, Group(D)=B1).

The server 10 uses this grouping pattern, that is, whether the beacons are grouped in a certain configuration (the number of groups, the number of beacons belonging to each group), and the user device 1 using the identification information of the beacons belonging to each group. It is possible to determine whether the area is located at the entry point, 1/3 point, 2/3 point, or exit point.

4 shows a rhombic beacon arrangement pattern. When the user device (1) is located at the entry point (U1) of the area, the beacon group has 4 groups (Group(A)=B1, Group(B)=B3, Group(C)=B2,B4, Group Grouped into (D)=B5), and when the user device (1) is located at the 1/3 point (U2) of the area, the beacon group consists of 3 groups (Group(A)=B1, B3, Group(B)). )=B2,B4, Group(C)=B5).

In addition, when the user device (1) is located at the 2/3 point (U3) of the corresponding area, the beacon group has 3 groups (Group(A)=B3,B5, Group(B)=B2,B4, Group(C)). )= B1), and when the user device 1 is located at the exit point (U4) of the corresponding zone, the beacon group has 4 groups (Group(A)=B5, Group(B)=B2,B4, Group(C)=B3, Group(D)=B1).

Meanwhile, in the present embodiment, that the received signal strength is similar means that the deviation of the received signal strength between beacons is less than the reference value.

The manager terminal 30 corresponds to a terminal device used by an administrator, that is, an employee of a medical institution (doctor, nurse, etc.), and provides information to the user device 1 or checks information on the location of the user device 1 Can perform the function

Specifically, the administrator terminal 30 may include a display and an input device, and the administrator may transmit announcements to the user device 1 through the administrator terminal 30, and transmit a message only to a specific user device 1. May be.

In addition, the manager may check information on the current location of each user device 1, information on a moving path, and the like through the manager terminal 30.

In addition, when a call occurs from the user device 1, the manager terminal 50 may display the location of the user device 1 and the contents of the call.

The medical information system 40 refers to an electnonic medical record (EMR), an order communication system (OCS), a picture archiving communication system (PACS), etc., which are generally built in medical institutions, and the server 10 is such a medical information system ( 40) can obtain patient information.

Meanwhile, the medical information system 40 may be in a form included in the system in this embodiment, but the medical information system 40 already built in a medical institution and the system according to the present embodiment operate in conjunction with each other. It could be.

As shown in FIG. 5, the server 10 first collects the received signal strength between the user device 1 and the beacon 20 (S200). The beacon 20 is connected to the server 10 by wired or wirelessly, and can transmit connection information with the user device 1 (eg, identification information of the user device 1, received signal strength (RSSI)) to the server 10. have.

Subsequently, the server 10 groups beacons having similar received signal strength (S210). The server 10 groups beacons whose received signal strength is less than or equal to a reference value among beacons into one group, and at this time, beacons whose received signal strength is less than or equal to a threshold may be excluded.

After the step S210, the server 10 calculates the location information of the user device 1 by using the grouping pattern calculated in the step S210 (S220). The space of the medical institution where the beacon 20 is installed may be physically or logically divided, and when a plurality of beacons 20 are arranged in a specific arrangement pattern for each divided zone, according to the movement of the user device 1 Since a change in the grouping pattern of beacons occurs, the server 10 can determine the location of the user device 1 by grasping it.

For example, the server 10 is the location information of the user device 1, and the user device 1 is located at any one of the entry point, 1/3 point, 2/3 point, and exit point of a specific area. Can be calculated.

Meanwhile, the calculated location of the user device 1 is transmitted to the administrator terminal, so that the administrator can easily find the patient.
