Referring to FIG. 1 , the infectious disease management system includes a plurality of wireless terminals 100 and a server 10 .

The plurality of wireless terminals 100 are portable electronic devices, and may correspond to any electronic device capable of communicating with one or more adjacent wireless terminals and the server 10 located in the vicinity of the wireless terminal 100 .

As an example, the electronic device may correspond to a smartphone. In addition, the electronic device may be implemented in the form of a tablet personal computer (PC), a mobile phone, a personal digital assistant (PDA), and/or a portable multimedia player (PMP).

The plurality of wireless terminals 100 may each perform a first function of broadcasting a broadcast message including terminal information to neighboring wireless terminals. In this case, the wireless terminal 100 in which the dangerous state information is registered may broadcast a broadcast message including the registered dangerous state information to neighboring wireless terminals.

In addition, when a broadcast message including terminal information is received from the plurality of wireless terminals 100 , the terminal information of the adjacent wireless terminals included in the broadcast message, and location/time information at the time of receiving the broadcast message A second function of storing may be performed, respectively.

Meanwhile, the broadcast message may include dangerous state information. In this case, the wireless terminal 100 that has received at least one broadcast message including the dangerous state information may output an alert.

Here, the plurality of wireless terminals 100 may activate or deactivate the first and second functions according to a command from the server 10 .

Meanwhile, in the plurality of wireless terminals 100 , an APP performing first and second functions may be installed in advance. In this case, the plurality of wireless terminals 100 may execute or terminate the corresponding app according to a command from the server 10 .

The wireless terminal 100 may store the stored information in units of a predetermined period as the second function is performed. The wireless terminal 100 may provide the stored information to the server 10 when there is a request from the server 10 . Meanwhile, when there is no information request from the server 10 for a predetermined period to elapse, the wireless terminal 100 may delete information of the target period. For example, when there is no request for the corresponding information from the server 10 so that two weeks have elapsed from the time when the information is stored, the wireless terminal 100 may delete the information after two weeks.

Accordingly, for a detailed description of the detailed configuration and function of the wireless terminal 100, refer to the embodiment of FIG. 2 .

The server 10 may communicate with a plurality of wireless terminals 100 and transmit a predetermined command to each wireless terminal 100 .

Also, the server 10 may transmit an activation command signal of the first and second functions to the wireless terminal 100 located in a country where an infectious disease is prevalent.

The range of the wireless terminal 100 to which the first and second function activation command signals are transmitted may be determined according to the transmission rate, incubation period, and mortality rate of the infectious disease.

The server 10 may request information stored in the wireless terminal 100 possessed by a specific person for the management of infectious diseases. As an example, the server 10 may request information stored in a wireless terminal of a person who has been diagnosed with an infectious disease (hereinafter, referred to as a 'confirmed person'). In this case, the server 10 may request only information corresponding to a predetermined period of information stored in the wireless terminal of the confirmed patient.

As an example, the server 10 may request information for the previous two weeks from the time when the confirmed person is confirmed with the infectious disease to the wireless terminal of the confirmed person.

The server 10 analyzes the information stored in the wireless terminal of the confirmed patient and extracts the terminal information and location/time information stored in the wireless terminal of the confirmed patient within a predetermined period. Here, the terminal information stored in the wireless terminal of the confirmed patient means terminal information of the surrounding wireless terminals received from the nearby wireless terminals. Here, the terminal information may include identification information for identifying nearby wireless terminals. In addition, the location/time information means location/time information at a time when a broadcast message is received from nearby wireless terminals. Therefore, the server 10 can check the movement path of the confirmed person based on the extracted terminal information, and can check the wireless terminal information of the person who has come into contact with the confirmed person (hereinafter, referred to as a 'contact person').

When the wireless terminal information of the contact is confirmed, the server 10 may transmit a danger alert for an infectious disease to the wireless terminal of the contact. In addition, the server 10 may also transmit information about visiting a medical institution for an infectious disease examination to the contact's wireless terminal.

Meanwhile, the server 10 may store risk state information on the infectious disease in the confirmed patient's wireless terminal, that is, the confirmed patient terminal, in order to prevent the spread of the infectious disease.

In this case, the terminal of the confirmed patient may generate a broadcast message including the dangerous state information together with the terminal information of the terminal of the confirmed patient when generating the broadcast message, and transmit the generated broadcast message to the neighboring wireless terminals.

Accordingly, the neighboring wireless terminals located near the confirmed patient may output an alert when a broadcast message including dangerous state information is received. Accordingly, people located in the vicinity of the confirmed patient can recognize that the confirmed patient is located in the vicinity through the alarm output of the nearby wireless terminal.

Meanwhile, the server 10 may transmit a deactivation command signal of the first and second functions to each wireless terminal 100 . For example, the server 10 may transmit a deactivation command signal of the first and second functions to each wireless terminal 100 when the infectious disease ends or the number of confirmed cases of the infectious disease no longer increases.

2 is a diagram illustrating a configuration of a wireless terminal according to an embodiment of the present invention.

Referring to FIG. 2 , the wireless terminal 100 may include a control unit 101 , a communication unit 102 , a storage unit 105 , and an interface unit 107 . Here, the control unit 101 may process a signal transmitted between each component of the wireless terminal 100 .

The first communication unit 103 may broadcast a broadcast message to neighboring wireless terminals according to a command of the control unit 101 . In this case, the first communication unit 103 may broadcast a broadcast message to a neighboring wireless terminal in real time or every predetermined period. Here, the surrounding wireless terminal is not fixed, and may correspond to any wireless terminal located in the vicinity of the wireless terminal, for example, in a broadcastable distance.

Also, the first communication unit 103 may receive a broadcast message from one or more neighboring wireless terminals. When a broadcast message is received from a neighboring wireless terminal, the first communication unit 103 may transmit it to the control unit 101 .

Here, the first communication unit 103 may use a frequency division communication method when broadcasting a broadcast message or receiving a broadcast message from a neighboring wireless terminal. The frequency division communication method refers to a method using different frequency channels when transmitting and receiving broadcast messages.

Accordingly, the first communication unit 103 may determine a transmission frequency channel by searching for a frequency channel available for broadcasting the broadcast message. When the transmission frequency channel is determined, the first communication unit 103 may broadcast a broadcast message to neighboring wireless terminals through the determined transmission frequency channel.

Similarly, the first communication unit 103 may receive the broadcast message through a reception frequency channel of a band different from the transmission frequency channel. In this case, when receiving a broadcast message from a plurality of neighboring wireless terminals, the first communication unit 103 may receive the broadcast message through different reception frequency channels.

Meanwhile, the first communication unit 103 may use a time division communication method when broadcasting a broadcast message or receiving a broadcast message from a neighboring wireless terminal. The time division communication method refers to a method in which a predetermined frequency channel is used when transmitting and receiving a broadcast message, but the frequency channel is divided into a predetermined time period and a broadcast message is transmitted or received during an empty time.

Accordingly, the first communication unit 103 may broadcast a broadcast message to a neighboring wireless terminal in a time division communication method through a predetermined frequency channel.

Similarly, the first communication unit 103 may receive a broadcast message in a time division communication method through a predetermined frequency channel.

Meanwhile, the first communication unit 103 may transmit and receive a broadcast message by mixing a frequency division communication method and a time division communication method.

Accordingly, the first communication unit 103 may determine an available transmission frequency channel by searching for a frequency channel, and broadcast a broadcast message to a neighboring wireless terminal in a time division communication method through the determined transmission frequency channel.

The transmission/reception method of the first communication unit 103 may be determined according to the communication environment of the wireless terminal 100 .

The second communication unit 104 may receive an activation command signal of the first and second functions from the server 10 . Also, the second communication unit 104 may receive a deactivation command signal of the first and second functions from the server 10 . The second communication unit 104 may receive information about the encryption key together when receiving the activation command of the first and second functions.

In this case, the second communication unit 104 transmits the activation command or the deactivation command of the first and second functions received from the server 10 to the control unit 101 .

As an example, the first and second communication unit 104 is a module for wireless Internet access or short-range communication (Short Range Communication).

The storage unit 105 may store data and/or algorithms required for the wireless terminal 100 to operate.

Accordingly, the storage unit 105 may store an app installed to perform the first function and the second function. In addition, the storage unit 105 may store data, instructions, and/or algorithms necessary for executing the first function and the second function. Also, the storage unit 105 may store information generated while performing the first and/or second function.

For example, the storage unit 105 may store terminal information and location/time information received from nearby wireless terminals while performing the second function. In this case, the terminal information may include unique identification information of a neighboring wireless terminal that has transmitted the broadcast message. Also, the location/time information may be information on a location and time at which a broadcast message is received from a neighboring wireless terminal.

Here, the storage unit 105 includes a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), a programmable read-only memory (PROM), and an electrically erasable programmable read (EEPROM). -Only Memory) may include a storage medium.

The interface unit 107 may include an input unit for receiving a control command from a user and an output unit for outputting an operation state and result of the wireless terminal 100 .

Here, the input means may include a key button, and may include a mouse, a joystick, a jog shuttle, a stylus pen, and the like. In addition, the input means may include a soft key implemented on the display.

The output means may include a display, and may include an audio output means such as a speaker. In this case, when a touch sensor such as a touch film, a touch sheet, or a touch pad is provided in the display, the display operates as a touch screen, and the input means and the output means are integrated.

In this case, the display includes a liquid crystal display (LCD), a thin film transistor liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), and a flexible display (Flexible Display). , a field emission display (FED), and a three-dimensional display (3D display) may include at least one.

When a command signal for activation of the first and second functions is received from the server 10 through the second communication unit 104 , the control unit 101 activates the first and second functions. In this case, the controller 101 may execute an app that performs the first and second functions.

When the first function is activated, the control unit 101 allows a broadcast message to be broadcast to a neighboring wireless terminal through the first communication unit 103 . In this case, the control unit 101 generates a broadcast message including terminal information of the wireless terminal 100 , for example, unique identification information of the corresponding wireless terminal 100 , and the generated broadcast message is transmitted to the first communication unit 103 . to be broadcast to nearby wireless terminals through

The controller 101 may generate a broadcast message including the encrypted terminal information after encrypting the terminal information using the encryption key received from the server 10 when generating the broadcast message including the terminal information.

Here, the controller 101 may periodically broadcast a broadcast message in real time or every predetermined time unit in a state in which the first function is activated. Accordingly, the first communication unit 103 broadcasts a broadcast message to the neighboring wireless terminals in real time or periodically under the control of the control unit 101 .

On the other hand, risk status information for an infectious disease may be registered in the wireless terminal of the confirmed patient. In this case, the controller 101 may generate a broadcast message including the unique identification information and the dangerous state information of the wireless terminal 100 and broadcast the broadcast message to the neighboring wireless terminals through the first communication unit 103 .

When the second function is activated, the control unit 101 allows reception of a broadcast message of a neighboring wireless terminal through the first communication unit 103 . In this case, the control unit 101 may allow reception of the broadcast message received through the first communication unit 103 only when the received signal strength indicator (RSSI) is equal to or greater than a preset threshold.

For example, the reference value for the received signal strength of the broadcast message may be determined based on an infection distance through which an infectious disease can be transmitted. In this case, the reference value may be set by the server 10 .

Accordingly, when a broadcast message having a received signal strength equal to or greater than the reference value is received through the first communication unit 103 , the control unit 101 extracts terminal information included in the broadcast message and stores the extracted terminal information in the storage unit 105 . In this case, the control unit 101 stores the location/time information at which the corresponding broadcast message was received together with the terminal information. The control unit 101 may store the terminal information and location/time information included in the broadcast message in the storage unit 105 after encryption using the encryption key received from the server 10 .

On the other hand, when a broadcast message having a received signal strength equal to or greater than a reference value is received through the first communication unit 103, the control unit 101 receives the same broadcast message more than a reference number of times within a predetermined time, the terminal information included in the broadcast message and the corresponding It is also possible to store location/time information at which the broadcast message was received.

Then, when there is a request for information stored in the storage unit 105 from the server 10 , that is, terminal information and location/time information stored based on the received broadcast message, the control unit 101 transmits the information to the server 10 . ) is sent to For example, when the user of the wireless terminal 100 is confirmed with an infectious disease, the server may request terminal information and location/time information stored in the wireless terminal of the confirmed patient for a predetermined target period. In this case, the controller 101 may extract only information within the target period requested by the server 10 and transmit it to the server 10 . Accordingly, the server acquires information on the wireless terminal of at least one contact who has come into contact with the confirmed person based on the terminal information and the location/time information stored in the wireless terminal of the confirmed patient, and sends a risk alert for the infectious disease to the wireless terminal of the contact. can send

Also, when there is no information request from the server 10 so that a predetermined period has elapsed, the controller 101 may delete information whose predetermined period has elapsed. For example, when the incubation period of an infectious disease is two weeks, the controller 101 may delete information after two weeks have elapsed.

The control unit 101 may check whether the dangerous state information on the infectious disease is included in the broadcast message received through the first communication unit 103 . If the broadcast message includes dangerous state information, the controller 101 may output an alert.

For example, the controller 101 may output an alert message regarding the risk of contact with an infectious disease through the display screen of the interface unit 107 . Also, the control unit 101 may output an alarm sound through a speaker of the interface unit 107 . In addition, the means for outputting the alert for the dangerous state information may be any means by which the user can recognize the alert situation.

Meanwhile, when a deactivation command signal of the first and second functions is received from the server 10 through the second communication unit 104 , the control unit 101 deactivates the first and second functions. In this case, the wireless terminal may delete pre-stored terminal information, location/time information, encryption key, and the like, and terminate the corresponding function.

3 is a diagram illustrating an embodiment referenced to explain a message broadcasting operation of a wireless terminal according to an embodiment of the present invention.

Referring to FIG. 3 , reference numeral 110 denotes a user's wireless terminal (user wireless terminal) as a reference, and reference numeral 120 denotes one or more wireless terminals (peripheral wireless terminals) located in the vicinity of the user wireless terminal 110 . it has been shown

When the first function is activated by the server 10, the user wireless terminal 110 generates a broadcast message including terminal information such as unique identification information of the user wireless terminal 110 to generate one or more neighboring wireless terminals 120 broadcast to In this case, the user wireless terminal 110 may encrypt the terminal information and generate a broadcast message including the encrypted terminal information. Here, the encryption key may be provided by the server 10 .

The user wireless terminal 110 may broadcast a broadcast message in real time or every predetermined period.

The broadcast message may be broadcast to the neighboring wireless terminal 120 using at least one of a frequency division method, a time division method, or a frequency division and time division mixing method.

Here, the frequency division communication method refers to a method of transmitting a broadcast message through the frequency channel by searching for a frequency channel of an empty band among a plurality of frequency channels.

The time division communication method refers to a method in which a broadcast message is transmitted using a predetermined frequency channel, but the broadcast message is transmitted during an empty time among the corresponding frequency channels.

The frequency division and time division mixing method refers to a method in which the frequency division communication method and the time division communication method described above are mixed. That is, the frequency division and time division mixing method refers to a method of determining a transmission frequency channel by searching an empty frequency channel, and transmitting a broadcast message through an empty time among the determined transmission frequency channels.

On the other hand, when the user wireless terminal 110 is a wireless terminal of a confirmed patient, the user wireless terminal 110 may store risk state information on an infectious disease.

In this case, the user wireless terminal 110 generates a broadcast message including not only terminal information but also dangerous state information. Accordingly, the user wireless terminal 110 broadcasts a broadcast message including terminal information and dangerous state information to the neighboring wireless terminal 120 .

4 is a diagram illustrating a first embodiment referenced to describe a message reception operation of a wireless terminal according to an embodiment of the present invention.

Referring to FIG. 4 , reference numeral 110 denotes a user's wireless terminal (user wireless terminal) as a reference, and reference numeral 120 denotes one or more wireless terminals (peripheral wireless terminals) located in the vicinity of the user wireless terminal 110 . it has been shown

When the second function is activated by the server 10 , the user wireless terminal 110 may receive a broadcast message from a plurality of neighboring wireless terminals 120 . The received broadcast message includes terminal information such as unique identification information of the neighboring wireless terminal 120 that has transmitted the corresponding broadcast message.

When one or more broadcast messages are received, the user wireless terminal 110 stores terminal information included in the broadcast message and location/time information at which the broadcast message was received. In this case, the user wireless terminal 110 may store the terminal information and the location/time information after encrypting it using an encryption key. Here, the encryption key may be provided by the server 10 .

5 is a diagram illustrating a second embodiment referenced to describe a message reception operation of a wireless terminal according to an embodiment of the present invention.

Referring to FIG. 5 , reference numeral 110 denotes a user's wireless terminal (user wireless terminal) as a reference, and reference numerals 121, 122, 123, and 124 denote wireless terminals located in the vicinity of the user wireless terminal 110 (periphery). wireless terminal).

When the second function is activated by the server 10 , the user wireless terminal 110 may receive a broadcast message from a plurality of neighboring wireless terminals 121 , 122 , 123 , and 124 . The received broadcast message includes terminal information such as unique identification information of the neighboring wireless terminals 121, 122, 123, and 124 that have transmitted the corresponding broadcast message.

Infectious diseases may infect a target within a predetermined distance depending on the nature of the virus. On the other hand, the probability of being infected with the virus is low for a target located at a distance greater than the maximum infection distance.

In addition, a received signal strength indicator (RSSI) at the time of receiving a broadcast message becomes weaker as the receiving distance increases.

Accordingly, the user wireless terminal 110 may receive and store only the broadcast message in which the received signal strength of the broadcast message is equal to or greater than a preset threshold. Here, the reference value for the received signal strength of the broadcast message may be determined based on an infection distance through which an infectious disease can be spread, and the reference value may be set by the server 10 .

In this case, the user wireless terminal 110 may store terminal information included in the received broadcast message and location/time information at which the broadcast message was received. The user wireless terminal 110 may store terminal information and location/time information after encrypting it using an encryption key. Here, the encryption key may be provided by the server 10 .

For example, the received signal strength of the broadcast message received from the neighboring wireless terminals (121, 122, 123) may be greater than or equal to a reference value. Accordingly, the user wireless terminal 110 may store each terminal information and location/time information included in the broadcast message received from the neighboring wireless terminals 121 , 122 , and 123 , respectively.

On the other hand, the received signal strength of the broadcast message received from the neighboring wireless terminal 124 may be less than the reference value. Accordingly, the user wireless terminal 110 does not store the information included in the broadcast message received from the neighboring wireless terminal 124 .

As another example, the same broadcast message may be repeatedly received from the neighboring wireless terminals staying in the vicinity of the user wireless terminal 110 for a long time.

Accordingly, when the same broadcast message is received more than a reference number of times within a predetermined time, the user wireless terminal 110 may store terminal information included in the broadcast message and location/time information at which the broadcast message was received. In this case, since information of a nearby wireless terminal staying in the vicinity of the user wireless terminal 110 is stored for a long time, the reliability of information stored in the user wireless terminal 110 may be increased.

6 and 7 are diagrams illustrating an embodiment referenced to describe a transmission/reception operation between a server and a wireless terminal according to an embodiment of the present invention.

Referring to FIG. 6 , the server 10 may activate the first and second functions of the wireless terminal when an infectious disease is prevalent in a specific region or multiple regions.

In this case, the server 10 may transmit the activation command signals of the first and second functions to the plurality of wireless terminals. In this case, the server 10 may transmit information about the encryption key together to a plurality of wireless terminals.

Accordingly, the wireless terminal receiving the activation command signal of the first and second functions from the server 10 may activate the first and second functions based on the received signal.

Here, the plurality of wireless terminals may be wireless terminals located in a specific area where an infectious disease is prevalent. In addition, the plurality of wireless terminals may be wireless terminals located in a specific area where an infectious disease is prevalent and in a surrounding area. In addition, the plurality of wireless terminals may be wireless terminals located in a country where an infectious disease is prevalent.

In addition, the server 10 may deactivate the first and second functions of each wireless terminal when the infectious disease is over or the number of confirmed infectious diseases is less than the reference value.

In this case, the server 10 may transmit a deactivation command signal of the first and second functions to the plurality of wireless terminals.

Accordingly, the wireless terminal receiving the deactivation command signal of the first and second functions from the server 10 may deactivate the first and second functions based on the received signal. In this case, the wireless terminal may delete pre-stored terminal information, location/time information, encryption key, and the like, and terminate the corresponding function.

On the other hand, when a confirmed case of an infectious disease occurs, the server 10 may request information stored within a predetermined period from the wireless terminal of the confirmed patient.

At this time, when there is a request from the server 10 , the wireless terminal of the confirmed patient transmits the information stored in the wireless terminal to the server 10 as shown in FIG. 7 . In other words, the wireless terminal of the confirmed patient may transmit the terminal information and location/time information stored within a predetermined period to the server 10 .

Accordingly, the server 10 can confirm the movement path of the confirmed patient for a predetermined period based on the location/time information stored in the wireless terminal of the confirmed patient. In addition, the server 10 may check the contact information of the confirmed person based on the terminal information and the location/time information stored in the wireless terminal of the confirmed person.

Accordingly, the server 10 may transmit a danger alert regarding the infectious disease to the wireless terminal of the contact in order to prevent the spread of the infectious disease.

In this case, the contact can recognize that he or she has come into contact with an infected person through the danger alert received through the wireless terminal.

In addition, the server 10 may also transmit information about visiting a medical institution for an infectious disease examination to the contact's wireless terminal. Accordingly, the contact person may visit a medical institution according to the medical institution visit guide and check whether or not they are infected with an infectious disease.

In addition, the server 10 may transmit information on the movement path of the confirmed patient to a safety management organization and/or a quarantine organization. Also, the server 10 may transmit information on the movement path of the confirmed patient to a wireless terminal located on the movement path or its vicinity.

8A and 8B are diagrams illustrating a third embodiment referred to for explaining an alert operation of a wireless terminal according to an embodiment of the present invention.

When a confirmed patient occurs, the server collects information stored in the confirmed patient's wireless terminal within a predetermined period. In other words, the server may collect information and location/time information of nearby wireless terminals stored within a predetermined period from the wireless terminal of the confirmed patient.

In this case, the server may check the movement path of the confirmed person based on the information collected from the wireless terminal of the confirmed person and identify at least one contact person who has come into contact with the confirmed person.

When the wireless terminal information of the contact is confirmed, the server generates an alert message to guide the contact with the confirmed person. In this case, the server transmits the generated alert message to the wireless terminals 121 , 122 , and 123 of the contact, respectively, as shown in FIG. 8A .

Accordingly, when an alert message is received from the server, the wireless terminals 121 , 122 , and 123 of the contactor output the received alert message on the display screen.

Here, an embodiment of the alert message output on the display screen of the wireless terminal of the contact will refer to FIG. 8B.

As shown in FIG. 8B , the alert message may include content such as “It was confirmed that contact with a confirmed patient of an infectious disease at 00:00 on 00/00 0000, please contact the nearest public health center.” Of course, this is only an example and is not limited to any one, and information guiding contact with a confirmed infectious disease person is included.

In this case, the wireless terminals 121 , 122 , and 123 of the contact may also output an alarm sound so that the contact can check the alarm message.

Therefore, the contact person can check the contact with the infected person through the alert message and respond according to the guidance. This can prevent further spread of an infectious disease when the contact comes into contact with another person without knowing that he or she has been in contact with the confirmed person.

9A and 9B are diagrams illustrating a fourth embodiment referred to for explaining an alert operation of a wireless terminal according to an embodiment of the present invention.

When a confirmed case of an infectious disease occurs, the server may register the dangerous state information in the wireless terminal 110 of the confirmed person.

Here, the dangerous state information is information for identifying that the corresponding wireless terminal is a wireless terminal of a confirmed patient of an infectious disease.

When the dangerous state information is registered, the wireless terminal 110 of the confirmed patient can transmit, as shown in FIG. 9A, not only the wireless terminal information but also the dangerous state information to the surrounding wireless terminal 120 when transmitting the broadcast message. have.

Accordingly, when a broadcast message is received from the wireless terminal 110 of the confirmed patient, the neighboring wireless terminal 120 stores the wireless terminal information of the confirmed patient included in the received broadcast message.

In this case, the broadcast message received from the wireless terminal 110 of the confirmed patient includes dangerous state information. Accordingly, when the dangerous state information included in the received broadcast message is confirmed, the surrounding wireless terminal 120 generates an alert message for alerting the risk of contact with an infectious disease and outputs it on the display screen.

Here, an embodiment of the alert message output on the display screen of the neighboring wireless terminal 120 is to refer to FIG. 9B.

As shown in Fig. 9b, the warning message is “There is an infectious disease confirmed person within a distance of 10m. There is a risk of contagious diseases, so please be careful.” Of course, this is only an example, and is not limited to any one, and information to guide the existence of a confirmed infectious disease is included in the vicinity.

In this case, the surrounding wireless terminal 120 may also output an alarm sound so that the user can quickly check the alarm message.

Therefore, the user of the nearby wireless terminal can check the location of the confirmed infectious disease through the alert message and quickly leave the area. This can prevent the further spread of the infectious disease due to the user's contact with the confirmed infectious disease.

The operation flow of the wireless terminal and the server according to an embodiment of the present invention configured as described above will be described in more detail as follows.

10 is a diagram illustrating an operation flow of a method for transmitting a broadcast message of a wireless terminal according to an embodiment of the present invention.

Referring to FIG. 10 , when the activation command signal and the encryption key for the first function are received from the server 10 ( S110 ), the wireless terminal activates the first function, that is, the transmission function of the broadcast message ( S120 ).

When the first function is activated, the wireless terminal extracts terminal information of the wireless terminal (S130), and at this time, the extracted terminal information is encrypted using the encryption key received in the 'S110' process (S140).

The wireless terminal may include the encrypted terminal information in the broadcast message in the process 'S140' and transmit it to the neighboring wireless terminals.

At this time, the wireless terminal searches for a radio frequency channel for broadcasting the broadcast message (S150). If there is no available frequency channel, the wireless terminal repeats the process 'S150' until an available frequency channel appears.

When it is confirmed that an available frequency channel exists (S160), the wireless terminal transmits a broadcast message through the corresponding frequency channel (S170).

Thereafter, the wireless terminal repeats the processes 'S130' to 'S170'. In this case, the wireless terminal may repeatedly perform the deactivation command signal for the first function from the server 10 until it is received.

11 is a diagram illustrating an operation flow of a method for receiving a broadcast message of a wireless terminal according to an embodiment of the present invention.

Referring to FIG. 11 , when an activation command signal and an encryption key for the second function are received from the server 10 ( S210 ), the wireless terminal activates the second function, that is, the reception function of a broadcast message ( S220 ).

The wireless terminal may receive a broadcast message from one or more neighboring wireless terminals as the second function is activated (S230).

At this time, the wireless terminal measures the received signal strength indicator (RSSI) of the broadcast message received from the neighboring wireless terminals (S240), and if the measured received signal strength (RSSI) is less than the preset reference value (T) ( S250), the process 'S230' may be re-performed without storing the information of the corresponding broadcast message.

On the other hand, if the received signal strength (RSSI) measured in the process 'S240' is greater than or equal to the preset reference value (T) (S250), the wireless terminal includes the location/time information at which the corresponding broadcast message was received and the surrounding wireless terminal included in the broadcast message. of terminal information may be stored (S260).

In the process 'S260', the wireless terminal may store the location/time information and the terminal information after encrypting it using the encryption key received in the process 'S210'.

12 is a diagram illustrating an operation flow of a method for receiving a broadcast message of a wireless terminal according to another embodiment of the present invention.

The wireless terminal may receive a broadcast message from one or more neighboring wireless terminals as the second function is activated (S330).

At this time, the wireless terminal measures a received signal strength indicator (RSSI) of a broadcast message received from a neighboring wireless terminal (S340). If the received signal strength (RSSI) measured in the process 'S340' is less than the preset reference value (T) (S350), the wireless terminal may re-perform the process 'S330' without storing information of the corresponding broadcast message.

If the received signal strength (RSSI) measured in the process 'S340' is greater than or equal to the preset reference value (T) (S350), the wireless terminal checks whether the same broadcast message is received repeatedly N times or more (S360, S370).

If the same broadcast message is not received repeatedly N times or more, the wireless terminal may re-perform process 'S330' without storing information on the corresponding broadcast message.

On the other hand, when the measured received signal strength (RSSI) is equal to or greater than the preset reference value (T), and the same broadcast message is repeatedly received N or more times, the wireless terminal receives the location/time information of the broadcast message and the broadcast message. It is possible to store terminal information of the included neighboring wireless terminals (S380).

In the process 'S380', the wireless terminal may store the location/time information and the terminal information after encrypting it using the encryption key received in the process 'S310'.

13 is a diagram illustrating an operation flow of an alert output method of a wireless terminal according to an embodiment of the present invention.

Referring to FIG. 13 , when a broadcast message is received from a neighboring wireless terminal (S410), the wireless terminal checks terminal information of the neighboring wireless terminal included in the received broadcast message (S420).

In this case, the wireless terminal may additionally check whether the received broadcast message includes risk status information for an infectious disease.

If the broadcast message received in step 'S410' includes dangerous state information on an infectious disease (S430), the wireless terminal determines that a confirmed person of the infectious disease exists nearby and outputs an alert (S440).

In the process 'S440', the alert on the infectious disease may be output through the display screen in the form of an alert message on the risk of contact with the infectious disease. In addition, an alert for an infectious disease may be output through a speaker in the form of an alert sound.

In addition, the alert for an infectious disease may be output in a form in which the user can recognize the risk of the infectious disease.

14 is a diagram illustrating an operation flow of a method for controlling a server according to an embodiment of the present invention.

Here, the plurality of wireless terminals to which the activation commands for the first and second functions and the encryption key are transmitted may be wireless terminals located in a specific area where an infectious disease has occurred, or wireless terminals located in the area where the infectious disease has occurred and its surrounding areas. have. Meanwhile, the plurality of wireless terminals may be all wireless terminals located in a country where an infectious disease has occurred.

Accordingly, the plurality of wireless terminals collect and store information for investigation and management of infectious diseases by performing first and second functions according to commands received from the server 10 .

The server 10 maintains the first and second functions of the plurality of wireless terminals in an activated state until the event for the infectious disease is terminated.

Meanwhile, when it is confirmed that the infectious disease event in a predetermined region or country has ended ( S530 ), the server 10 may transmit a deactivation command for the first and second functions to a plurality of wireless terminals, respectively ( S540 ).

In this case, the server 10 may transmit a deletion command of the encryption key together in the process 'S540'.

Accordingly, the plurality of wireless terminals inactivate the first and second functions according to the command received from the server 10 , and delete the encryption key received from the server 10 .

15 is a diagram illustrating an operation flow of a method for managing an infectious disease in a server according to an embodiment of the present invention.

Referring to FIG. 15 , when a confirmed person of an infectious disease occurs ( S610 ), the server 10 may register risk status information on the infectious disease in the wireless terminal of the confirmed person ( S615 ).

In addition, the server 10 may request information stored for a predetermined period from the wireless terminal of the confirmed patient (S620). Here, the information stored for a predetermined period means information about neighboring terminals and location/time information stored in the wireless terminal of the confirmed patient.

When the information requested from the wireless terminal of the confirmed patient is not received ( S630 ), the server 10 may re-request the information.

On the other hand, when the requested information is received from the wireless terminal of the confirmed patient (S630), the server 10 analyzes the received information (S640), and checks the movement path of the confirmed person and the terminal information of the contact the confirmed person has contacted (S650). ).

When the movement path of the confirmed person and the terminal information of the contact are confirmed through the processes 'S640' and 'S650', the server 10 transmits an infectious disease contact risk alert to the contact's wireless terminal (S660).

Accordingly, the contactor can recognize the risk of contacting the infectious disease received through the wireless terminal.

Although not shown in FIG. 15 , the server 10 may transmit information on the movement path of the confirmed person confirmed through the processes 'S640' and 'S650' to a safety management institution and/or a quarantine institution. Also, the server 10 may transmit information on the movement path of the confirmed patient to a wireless terminal located on the movement path or its vicinity.
