Hereinafter, a real-time location tracking system according to an embodiment of the present invention will be described in detail.

1 to 3, the real-time location tracking system 1 proposed by the present invention comprises a wrist band 3, a position transmitter 5 placed in the building for transmitting a position signal, A router 7 for transmitting a position signal, and a server 9.

To describe this real-time location tracking system in more detail,

The wrist band 3 is a mobile communication terminal worn by the user on the wrist, and has a unique IP for each band 3. Then, the wrist band 3 receives the position signal transmitted from the position transmitter 5 and transmits the current position information based on the unique IP. The originated location information may be transmitted to the server 9 of the station through the router 7 and the wireless LAN network 11. [

The wrist band (3) comprises a case (13) provided with a band (3) to be worn on the wrist; An input unit 15 mounted inside the case 13 to receive a signal; A temperature sensor 17 for measuring the body temperature of the user; A three-axis sensor 19 for detecting movement; A vibration motor (21); A CPU 23 for processing current position information and motion and temperature data in cooperation with the sensor and the input unit 15; A memory (25) for storing data; An output unit 27 for transmitting a result processed by the CPU 23 to the outside; And a power supply unit 29.

In the wrist band 3 having such a structure, the input unit 15 means an antenna for receiving a signal received from the outside, that is, a signal received from the beacon 5.

The input unit 15 may be a function button arranged outside the case 13 to set a function, an emergency button, or the like.

The temperature sensor 17 is disposed in the case 13 to sense the ambient temperature, for example, to measure the user's body temperature. Various types of sensors can be applied to the temperature sensor 17, for example, a thermocouple, a temperature measuring resistor, a thermistor (NTC, PTC, CTR), a metal thermometer, and a thermo-sensitive ferrite sensor.

The temperature sensor 17 measures the body temperature of the user and transmits the result to the CPU 23. [

The three-axis sensor 19 measures the direction, the rotation, and the vibration by measuring the acceleration acting on the three axes of the X axis, the Y axis, and the Z axis. For example, a three-axis sensor 19, a six-axis sensor, and the like are applicable to the three-axis sensor 19.

The three-axis sensor 19 senses the movement of the user and transmits the resultant value to the CPU 23. Therefore, the CPU 23 processes the resultant value and transmits it to the server 9, and the server 9 judges whether the user is currently moving or not moving.

If the server 9 does not move for more than a predetermined time, it is determined that an abnormality has occurred to the user and the hospital or the guardian is contacted.

The vibration motor 21 has a structure in which an eccentric weight is mounted on the rotation shaft of the motor. Therefore, when a certain time or a specific event is generated by the control of the CPU 23, the eccentricity further rotates to generate vibration. Therefore, the user can recognize that the vibration or the vibration has occurred due to the vibration of the vibration motor 21.

The CPU 23 interlocks with the various sensors to determine whether the current position, the body temperature, the alarm, the abnormality of the movement, and the like are detected, and transmits the signal to the outside.

That is, the CPU 23 determines the current motion state of the user based on the resultant value input from the three-axis sensor 19. That is, if motion is not detected for a predetermined time, it is determined that an error has occurred to the user and an alarm signal is transmitted to the outside.

More specifically, the CPU 23 grasps the current user's body temperature based on the temperature value transmitted from the temperature sensor 17 of the wrist band 3. If this temperature value is higher or lower than the predetermined reference temperature value and deviates from the normal range, it is determined that an abnormality has occurred.

Therefore, the CPU 23 warns around the warning lamp or the speaker 33 when an abnormality occurs.

Then, the CPU 23 can judge whether there is an abnormality more accurately by interlocking the digital clock and the three-axis sensor 19 with each other.

In other words, it is possible to clearly distinguish the case where there is no motion due to sleeping and the case where there is no motion due to an abnormality by setting the motion reference time of bedtime and daytime differently.

For example, if there is no movement for 10 minutes during the daytime, it is judged as abnormal, but if there is no movement for 1 hour at the bedtime, it is judged as abnormal.

Then, the CPU 23 interlocks the signals of the temperature sensor 17 in addition to the three-axis sensor 19 and the digital clock.

That is, in the above-mentioned case, if the sleeping time does not move for one hour, the abnormality is determined, and at the same time, the body temperature value is also calculated, and if the body temperature is lower than or equal to a certain range, an alarm signal is issued even after one hour has elapsed.

The output unit 27 includes an output port 30 for transmitting the result calculated by the CPU 23 to the outside and an output port 30 for displaying characters, A display window 31; And a speaker 33 for generating a sound, a warning sound, and an operation sound.

The output port 30 transmits a signal to the router 7 using a predetermined frequency band. At this time, the frequency can be varied in various bands, and preferably a frequency in the 400 MHz band is used.

The display window 31 is preferably a LED-type display language, and displays time. Then, characters and the like transmitted from the control station can be displayed.

The user can see the character of the display window 31 and can grasp the current situation more clearly.

An alarm button is disposed on one side of the case 13 of the wrist band 3. Accordingly, the user can generate an alarm sound through the speaker 33 of the output unit 27 by pressing the alarm button. At the same time, a signal can be transmitted to the router 7 via the output unit 27 to contact the controller.

In addition, the wrist band 3 may be optionally equipped with an NFC chipset.

Near Field Communication (NFC) is a non-contact, short-range wireless communication module using 13.56Mhz frequency band, which means transmitting data at a distance of 10cm.

By mounting the NFC chipset on the wrist band 3, reading and writing information can be performed by interlocking with a card, a terminal, and a tag supporting NFC, and various functions such as approval and authentication can be performed.

Then, the wrist band 3 receives the position signal from the position transmitter 5 arranged in the building. Various types of transmitters 5 are applicable to the position transmitter 5, for example beacon 5 is applicable.

The beacon 5 is based on the Bluetooth 4.0 (BLE) protocol, and a unique IP value is set for each beacon 5. The beacon 5 is a device capable of communicating at distances up to 70 m. The beacon 5 transmits a signal to the wrist band 3 using a predetermined frequency band. At this time, the frequency can be varied in various bands, and preferably a frequency in the 400 MHz band is used.

The beacon 5 is disposed at an appropriate place in the building and transmits a position signal at a predetermined time interval, so that the wrist band 3 worn by the user can sufficiently receive the position signal.

Then, the wrist band 3 grasps the signal IP having the strongest strength among the signals of the beacons 5 to be received.

On the other hand, the router 7 is disposed at a predetermined position of the building, and transmits a signal transmitted from the wrist band 3 to the station through the network 11.

The router 7 is a device that reads the IP of the destination contained in the transmission information (packet) and transmits it to another communication network using the most appropriate communication path when information is exchanged between the different networks.

For example, to relay different local area networks (LANs) or to connect a local area network to a wide area network (WAN).

The router 7 of the present invention uses a predetermined frequency band and preferably uses a frequency band of 400 MHz.

The routers 7 may be arranged at predetermined positions in the interior of the building, for example, for each layer, and may be arranged at regular intervals in the corridors of the same layer. Accordingly, when a signal is received from the wrist band 3 worn by a plurality of users, the signal can be transmitted to the server 9 of the controller through the WLAN network 11.

The server 9 of the control station can grasp the current position of the user in real time through the router 7 and the wireless LAN network 11, and can also receive, process and direct the real time information.

The server 9 processes the signal transmitted from the wrist band 3 by loading the software of the ASN algorithm technique and performs appropriate processing according to information such as temperature data, position data, motion detection data, and alarm.

That is, when the emergency signal is received from the wrist band 3, the server 9 informs the user of the emergency by informing the user of the smartphone.

Fig. 4 shows a screen format displayed on a monitor disposed in a control station, in which a real-time location tracking system of the present embodiment is applied to a hospital.

As shown in the figure, a patient room placed on each floor in a hospital building is shown, and patients worn with a wrist band 3 are displayed in each room with a symbol, so that the current state can be grasped at a glance.

That is, when each patient moves in a building of a hospital with the wrist band 3 worn, a position signal transmitted from the beacon 5 fixed to each position is received by the wrist band 3 .

The wrist band 3 grasps the IP of the signal having the strongest strength among the received position signals as a corresponding position and transmits the position to the router 7 installed in the corridor or the like.

The router 7 receiving the position signal transmits a signal to the neighboring router 7 or transmits the signal to the server 9 of the controller through the network 11.

Therefore, the server 9 of the control station processes this signal and displays it on the monitor, and the status of each patient is displayed on the monitor in a divided manner.

For example, the patient is classified into a normal state, a non-working state, a non-wearing state, and a doctor calling state.

If it does not work, it can be regarded as a case where an abnormality occurs in the patient. In such a case, it is identified as an emergency situation and quick action is taken.

In addition, the wrist band 3 worn by each patient measures the body temperature of the patient and transmits it to the server 9 through the router 7. The server 9 judges whether or not the body temperature of the patient is abnormal and takes measures when necessary.

In this way, the current position and health status of each patient in the hospital can be grasped in real time so that appropriate emergency measures can be taken promptly.

The wrist band may be classified into a patient, a doctor, and a nurse.

That is, by inputting the user's ID to the memory of the wrist band and the CPU in advance, the server can recognize whether the person using the wrist band is a medical person such as a doctor or a nurse or a patient.

Therefore, the patient and the medical person can be identified based on the symbols displayed on the monitor of the server, and when an abnormality occurs in the patient, the adjacent medical person can be called.

Although the above-described position tracking system is applied to a hospital as an example, the present invention is not limited to this, and can be applied to various industrial fields.

For example, it can be applied to a mine, a route, a large cargo base, a specific restricted area, etc., so that it can quickly grasp the real time location and the like.

Particularly, when a wrist band is used for a mine, moisture may be caught inside the wrist band due to its deep underground environment.

Therefore, in order to remove such moisture, a depth measuring sensor and a heating member may be mounted on the wrist band.

That is, by attaching the depth measurement sensor to the wrist band and connecting it to the CPU 23, the corresponding depth can be recognized in real time. When the temperature falls below a predetermined depth, the CPU 23 generates heat by transmitting a signal to a heating member such as a heating coil or a heating plate, thereby removing moisture.

As such, it is convenient to remove moisture even in a deep underground environment such as a mine.
