Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention of the user, the operator, or the custom. Therefore, the definition should be based on the contents throughout this specification.

Hereinafter, embodiments of a user terminal will be described in detail with reference to the drawings.

1 is a configuration diagram of a user terminal according to an example.

Referring to FIG. 1, a user terminal 100 may include a beacon signal sensing unit 110, an authentication request unit 120, and an environment information providing unit 130.

According to an example, the beacon signal sensing unit 110 may sense a beacon signal transmitted from the beacon terminal. The beacon signal sensing unit 110 periodically senses a beacon signal so that the user terminal can sense whether it is in a range in which it can communicate with the beacon terminal. Here, the beacon terminal may relay one or more of the user terminal and the environment information server, and may operate as an access point (AP) of the user terminal. In this case, the communication between the user terminal and the environment information server is generally performed through the beacon terminal, and a description of the communication path between the user terminal and the environment information server may be omitted for convenience of explanation.

According to an example, when the beacon signal detection unit 110 detects a beacon signal, the authentication request unit 120 may request the environment information server to authenticate the user terminal through the beacon terminal. The authentication requesting unit 120 may request the environment information server to authenticate the user terminal so that the user terminal can use the environment information collected and stored in the environment information server. Here, the authentication of the user terminal may be performed by the authentication performing unit 310 by registering the unique identification number of the user terminal with the environment information server through the beacon terminal, Authentication can be completed by receiving the authentication key and inputting it at the user terminal. In this manner, security can be ensured by allowing access only to terminals that have been authenticated by the environment information server through the beacon terminal.

The authentication request unit 120 may request approval of the environment information collected by the environment information server when the authentication of the user terminal is completed. For example, the authentication request unit 120 can request environment information collected in a predetermined space including a user terminal by using the location of the user terminal, request environmental information of a specific space according to the setting of the user It is possible. Here, the environmental information may include at least one of temperature, weather, humidity, fine dust concentration, carbon dioxide concentration, volatile organic compound concentration, and discomfort index, but is not limited thereto.

According to an example, when the use of the environment information of the authenticated terminal is approved, the environment information providing unit 130 may receive the environment information from the environment information server to provide environment information to the user, The environment information may be environment information for a predetermined space based on the position of the storage medium. At this time, the environment information providing unit 130 may not only receive environment information from the environment information server but also collect environmental information of the space to which the user terminal belongs and provide the environment information server. Hereinafter, the authentication request unit 120 and the environment information providing unit 130 will be described in detail with reference to FIGS.

2 is a configuration diagram of the authentication request unit 120 according to an example.

2, the authentication requesting unit 120 may include a terminal information transmitting unit 121, an authentication key receiving unit 122, and a usage approval requesting unit 123. [

According to an example, when the beacon signal detection unit 110 detects a beacon signal, the terminal information transmission unit 121 may transmit the location information of the user terminal or the unique identification information of the user terminal to the environment information server. For example, the location information of the user terminal can estimate the location information of the user terminal by measuring the intensity of the beacon signal transmitted from the beacon terminal. When the terminal information transmitter 121 communicates with two or more beacon terminals, The location of the user terminal can be estimated based on the location information of the installed beacon terminal. If it is difficult to estimate the location information of the user terminal by measuring the intensity of the beacon terminal by locating the user terminal in the bag or bag of the user, the location information of the installed beacon terminal is transmitted to the environment information server And estimate the location of the approximate user terminal. That is, if the accurate position estimation of the user terminal is possible according to the reception sensitivity of the beacon signal, the terminal information transmitter 121 transmits the position information of the user terminal to the environment information server, It is possible to transmit the location information of the terminal to the environment information server.

In addition, the beacon terminal is more accurate in location distinction, consumes less power, and can provide accurate position information even in the room, compared to the previous GPS, which receives a signal transmitted from a satellite and calculates a user's position. If the user terminal includes the GPS module and the reception sensitivity of the satellite signal is good, the location of the user terminal determined through the GPS may be transmitted to the environment information server, and the received beacon signal and the satellite signal may be complementary So that the exact position of the user terminal can be determined.

Here, the unique identification information of the user terminal may be International Mobile Equipment Identity (IMEI) or Personal Identification Number (PIN), but is not limited thereto. The user terminal may be terminal information that can be distinguished from each other in the environment information server. In addition, the terminal information transmitted from the user terminal can be used for updating the environment information collected in the environment information server or in the statistics of the received environment information, and a detailed description will be given later.

According to one example, the authentication key receiving unit 122 can receive the authentication key from the environment information server. The authentication key received here may be an authentication key generated based on the received terminal information of the environment information server, and the generation of the authentication key will be described later.

Meanwhile, the authentication key receiving unit 122 can perform authentication by receiving the authentication key transmitted from the environment information server. However, the present invention is not limited thereto, and authentication may be performed by receiving an authentication key and inputting a security code corresponding to the authentication key received at the user terminal.

According to one example, the use approval requesting unit 123 may request the environmental information server to approve the use of the environment information. When the authentication of the user terminal is normally completed in the authentication request unit 120, the use approval request unit 122 may request the environment information server to approve the use of the environment information based on the received authentication key. At this time, May be environment information of a predetermined space including the user terminal, statistical information of the collected information, specific time, and environment information of the area.

FIG. 3 is a configuration diagram of an environment information providing unit 130 according to an example.

Referring to FIG. 3, the environment information providing unit 130 may include an environment information collecting unit 131, an environment information requesting unit 132, and an information output unit 133.

According to one example, the environment information collecting unit 131 can collect environment information when the approval of the use of the environment information is completed from the environment information server. At this time, the environment information collecting unit 131 can collect environment information of a predetermined space where the user terminal is located through an environmental information collection sensor (not shown).

For example, the environmental information collection sensor (not shown) may be, but is not limited to, a noise measurement sensor, an air component measurement sensor, an air pressure sensor, an altitude sensor, and a temperature sensor. In addition, environment information that can be collected may vary depending on the attached environment information collection sensor. In addition, when there is no sensor capable of collecting environmental information in the user terminal, environmental information may not be collected but environment information may be received from the environmental information server as soon as the environmental information use approval is completed.

The environment information collecting unit 131 may transmit the collected environment information to the environment information server through the beacon terminal. By transmitting the environmental information collected by the user terminal, which has been approved by the user terminal to the authentication and use of the environment information, to the environment information server, it is possible to prevent the collection of the environment information without the user's consent, .

According to another example, the environment information collecting unit 131 collects environment information at predetermined time intervals while being within the communication range of the beacon terminal connected to the environment information server, and transmits the collected environment information through the beacon terminal in real- And may transmit statistical information of the collected environment information to the environment information server.

According to an example, the environment information requesting unit 132 may request the environment information server to provide environment information when the environment information use approval from the environment information server is completed. Here, the requestable environment information does not need to match with the environment information collected by the environment information collecting unit 131 and transmitted to the environment information server, and it is possible to request various types of environment information stored in the environment information server.

According to another example, the environment information requesting unit 132 may request environment information of a predetermined space in which the current user terminal is located based on the location information of the user terminal, And may request environmental information of the space.

In addition, the environment information requesting unit 132 may receive the environment information transmitted from the environment information server according to the environment information providing request.

According to an example, the information output unit 133 may display the received environment information on the display of the user terminal. The display may be different depending on the type of the user terminal, and may be sufficient if the user can distinguish the visual display information. In addition, the information output unit 133 may include an input unit capable of touch input. When receiving at least one environment information, the information output unit 133 may display the respective environment information by dividing the environment. In accordance with a predetermined criterion, So that environmental information can be displayed. For example, fine dust, ozone, and carbon monoxide concentration are divided into the following categories: "good" when the carbon monoxide concentration is 0 to 2 ppm, "normal" when the carbon monoxide concentration is 2.01 to 9 ppm, "poor" when the carbon monoxide concentration is 9.01 to 15 ppm, 'Very Poor', each of which can be displayed in different colors such as blue, green, yellow and red.

According to one example, when the environment information collected by the environment information collecting unit 131 or received from the environment information server by the environment information requesting unit 132 exceeds a preset threshold value, the information output unit 133 may visually (Eg, display blinking on the information output), tactile (eg, vibration), and audible (eg, ringing) notifications.

For example, when the carbon monoxide concentration in the received environmental information is 'good' in the case of 0 to 2 ppm, 'normal' in the range of 2.01 to 9 ppm, 'bad' in the range of 9.01 to 15 ppm, 'Very bad', and when the concentration of carbon monoxide is 2.01 ppm or more, the user can be informed of carbon monoxide information. The information output unit 133 may provide notifications based on the environment information collected by the environment information collecting unit 131 and may use the statistical information about the predetermined period of the environment information received by the environment information requesting unit 132 To provide notifications.

According to another example, the information output unit 133 may include a user interface that displays the authentication state of the user terminal, the result of request for permission to use the environment information, and the environment information notification, and can control transmission / reception of environment information . For example, when the beacon signal sensing unit 110 senses the beacon signal from the beacon terminal, the information output unit 133 can indicate that the user terminal is in a state of being able to communicate with the environment information server, When the environmental information server approves the use of the environmental information according to the request for approval of the use of the environmental information, the approval completion message can be displayed.

The environment information providing unit 130 may further include an application executing unit (not shown) for controlling the user terminal. The user interface (UI) displayed on the information output unit 133 may include an environment information application .

4 is a flowchart illustrating an environment information providing method according to an example. 4 is an example of an environment information providing method for providing environment information collected using a user terminal to a user terminal.

Referring to FIG. 4, the user terminal 100 may sense a beacon signal transmitted from the beacon terminal (410).

After the user terminal detects the beacon signal, the user terminal 100 may receive the authentication key transmitted from the environment information server and perform authentication (420). At this time, authentication of the user terminal may be performed only by receiving the authentication key, but it is also possible to complete the authentication by inputting the security code corresponding to the received authentication key. At this time, the authentication may be that the user terminal has a valid authority and can be connected to the environment information server.

Meanwhile, the user terminal may transmit the terminal information including at least one of the location information and the identification information of the user terminal before sensing the beacon signal and receiving the authentication key transmitted from the environment information server. Therefore, the authentication key received for authentication of the user terminal may be based on the terminal information transmitted by the user terminal. For example, the received authentication key refers to a predetermined space including the user terminal based on the location information of the user terminal, and can be transmitted to the display of the user terminal to "Inha University library lobby & The user terminal may be authenticated by pressing a button.

After authentication of the user terminal is made valid, the user terminal may access the environment information server and request permission to use the environment information (430). It is possible to secure the reliability of the data load and environment information of the environment information server and the security of the user terminal by blocking the connection of the environment information server of the terminal that has not performed valid authentication.

If the user terminal is allowed to use the environment information, the user terminal can receive environment information from the environment information server (440). The type and range of the environment information received here may be varied based on frequency of connection of the user terminal and the frequency of providing environment information, and may be provided without limitation and without differences.

Meanwhile, the user terminal not only receives environment information collected from the environment information server but also collects environment information of a predetermined space including the user terminal and transmits the collected environmental information to the environment information server, It is also possible to receive.

The user terminal may then display the received environment information (450). For example, it is possible to divide environmental information received on a display capable of distinguishing visual display information into segments. On the other hand, the user terminal can display the received environment information on the touch-enabled display, and the user can touch the displayed environment information by dividing the division, and the user can touch the displayed environment information with detailed information such as change amount per month, It is possible to confirm the information.

Further, the user terminal may not only display the received environment information, but may also provide a notification to the user based on the received environment information. For example, the user can set a threshold value for each environment information. If the received environment information exceeds a predetermined threshold value, the user can visually (e.g., display blinking on the information output unit), tactile ), And audible (e.g., ringtone) notifications.

Specifically, when the carbon monoxide concentration in the received environmental information is in the range of 0 to 2 ppm, it is classified as 'good', in the range of 2.01 to 9 ppm in the 'normal' range, in the range of 9.01 to 15 ppm in the range of 'poor' When the concentration is 2.01 ppm or more, it is possible to provide carbon monoxide information notification to the user.

5 is a configuration diagram of an environmental information management system according to an example.

Referring to FIG. 5, the environment information management system 500 may include a user terminal 100, a beacon terminal 200, and an environment information server 300. The user terminal 100 is the same as the user terminal described above and will be described in detail below with respect to an environment information management system, mainly a beacon terminal and an environment information server.

At least one beacon terminal 200 may be installed within a range in which the beacon terminal 200 can communicate with the environment information management server and relay the communication between the user terminal and the environment information server.

According to an example, the beacon terminal periodically transmits a beacon signal to detect whether a user terminal capable of communicating with the environment information server has entered within the communication range of the beacon terminal, and can transmit the location information of the detected user terminal to the environment information server have. For example, if a user terminal capable of communicating with the environment information server is found, the beacon terminal can transmit accurate location information transmitted from the user terminal to the environment information server. If it is difficult to accurately locate the user terminal due to signal interference, Can be transmitted to the environment information server to transmit the location of the approximate user terminal.

On the other hand, since the beacon terminal can be easily installed indoors, compared to the previous GPS which receives the signal transmitted from the satellite and calculates the position of the user, the beacon terminal can accurately detect the position of the user even in an environment where satellite signals are difficult to reach, .

In addition, since the beacon terminal can be easily installed in the indoor or underground space, it is installed in an area where a large number of people frequently enter and exit but the ventilation is not easy, such as a department store, a library, a large- Information can be easily collected and easily provided to a user.

6 is a configuration diagram of an environment information server according to an example.

6, the environment information server 300 includes an authentication performing unit 310, a terminal registration unit 320, a usage approval processing unit 330, an environment information management unit 340, a terminal information database 350, (360).

When the user terminal information is received via the beacon terminal 200, the authentication performing unit 310 may generate and transmit an authentication key for authentication of the user terminal. The authentication may be that the user terminal corresponding to the received terminal information grants a valid authority to use the collected environment information.

For example, unnecessary data load may occur in the beacon terminal 200 and the environment information server 300 when the user terminal can access the environment information server 300 through the beacon terminal 200 without any authentication procedure, And the authentication performing unit 310 performs the authentication of the user terminal connected to the beacon terminal 200 to secure the reliability of the collected environment information and the security of the user terminal .

Meanwhile, the authentication performing unit 310 may generate an authentication key for authentication of the user terminal and transmit the generated authentication key to the user terminal. However, according to the degree of security of the environment information system, And transmits the generated authentication key to the user terminal, compares the security code inputted by the user from the user terminal with the security code corresponding to the authentication key, If they match, the authentication may be determined to be valid and the authentication may be completed.

According to another example, the authentication performing unit 310 can generate a security code having a different authority according to the operation requirement of the environmental information management system 400. [ For example, when the user terminal is classified as a portable mobile communication terminal, it is possible to generate a high-level security code in order to prevent leakage of location information of the user and to guarantee the reliability of the received environment information. Accordingly, It is possible to grant a higher authority to the terminal and generate and assign a relatively low-grade security code in the case of a fixed terminal similarly to collect only environment information.

According to an example, the terminal registrar 320 may register the user terminal in the terminal information database 350 using the received user terminal information. For example, when the user terminal requests the authentication, the terminal registration unit 320 inquires the history of the user terminal connected to the environment information server 300 from the terminal information database 350 to request initial authentication, And can register the unique identification number of the user terminal in the terminal information database 350 using the received terminal information. In addition, the terminal registration unit 320 inquires whether the terminal is registered in the terminal information database 350 in which the connection history of the environment information server 300 of the user terminal is stored, and can immediately perform authentication of the user terminal .

Meanwhile, the terminal information database 350 can store and manage the collected terminal information. For example, the terminal information database 350 may be classified according to recent access frequency, access area, and access time according to the unique identification number of the user terminal requesting authentication.

According to an example, the use approval processing unit 330 may process the approval of the use of the environment information when receiving the request to approve the use of the environment information from the user terminal that has received the authentication key. For example, when the authentication performing unit 310 has completed the authentication by transmitting the authentication key to the user terminal, the use approval processing unit 330 may use the environment information according to the environmental information use approval request of the user terminal having the valid authority You can approve.

According to one example, the use approval processing unit 330 may process approval of use of environment information based on whether or not the user terminal is registered. For example, based on the connection history of the user terminal stored in the terminal registration unit 320, the use approval processing unit 330 can set a difference in the available environment information as the frequency of access to the user terminal and the frequency of providing the environment information are higher .

For example, when there are user terminals A and B each having a frequency of access to the user terminal 10 times, and the frequency of providing environment information of each terminal is 5 times and 10 times, respectively, the use approval processing unit 330 transmits environment information The use of a wider range of environmental information can be approved for the user terminal B than the user terminal A in consideration of the contribution of the frequency. However, the present invention is not limited to this, and it is also possible to process the approval of the use of the environment information in accordance with the request for permission to use the user terminal having the valid authority after having been authenticated.

According to another example, when the user terminal that has completed the authentication using the security code requests the use approval, the use approval processing unit 330 sets a difference in the use of the environment information according to the rating of the issued security code, can do. For example, a user terminal that has completed authentication through a high-level security code can freely use all of the collected environment information, while a terminal that has completed authentication through a low-level security code can use the environment information provided by the terminal It is possible to set a differential so as to be accessible.

On the other hand, the use approval processing unit 330 can prioritize the use approval of the user terminal based on the terminal information stored in the terminal information database 350 to process the use approval. In this case, when the connection delay of the environmental information management system 500 occurs due to exceeding the number of user terminals connectable to the user terminal requesting authentication to the environmental information management system 500, Or to provide environmental information first.

For example, based on the recent frequency of access of the user terminal stored in the terminal information database 350, the use approval processing unit 330 may preferentially assign a higher priority to a user terminal having a higher access frequency, . ≪ / RTI > In addition, when priority is given based on the connection area, the user terminal moves relative to the user terminal always accessing the environment information management system 500 in the same area, and accesses to the environment information management system 500 in a plurality of areas It is also possible to collect environmental information of a plurality of areas in various ways by giving priority to a user terminal to be tried.

 According to an example, the environment information management unit 340 may update the stored environment information while storing the received environment information in the environment information database 360. [ Here, the update of the environment information may be to replace the stored environment information with the received environment information, and may be statistical information such as an average value of the environment information received for a predetermined time. For example, since the environmental information about the temperature often concerns the current temperature rather than the average temperature of the temperature change during the day, it is possible to replace the stored temperature information with the environment information received at the user terminal, It is also possible to update the stored temperature information to an average value of the temperature information collected for a relatively short period of time (e.g., 5 minutes).

In addition, when the user terminal is a mobile communication terminal, the environment information management unit 340 may receive the environment information of the changed location on the basis of the location information changed in accordance with the movement of the user terminal, and may update the environment information database 360 have. For example, when a user carrying the user terminal moves out of a predetermined area, the environment information management unit 340 can update the environment information database 360 in the predetermined space after moving using the location information of the moved user terminal Do.

On the other hand, when the user terminal requests the environment information provision, the environment information management unit 340 can transmit the environment information stored in the environment information database 360 to the user terminal based on the terminal information transmitted from the user terminal. For example, the environment information management unit 340 acquires environment information of a predetermined space in which a current user terminal is located, from the environment information database 360, without specifying any specific information based on the terminal information received from the user terminal, The environment information of the specific space requested by the user terminal may be acquired from the environment information database 360 and provided to the user terminal.

Here, the terminal information may be the location information of the user terminal, and when it is difficult to determine the accurate location of the user terminal according to the degree of goodness of the communication state between the beacon terminal 200 and the user terminal, To the environment information server 300 to provide an approximate location of the user terminal.

The environment information management unit 340 can manage the terminal information and environment information stored in the terminal information database 350 and the environment information database 360 in association with each other. For example, the environment information management unit 340 can manage environment information of the environment information database 360 for each terminal stored in the terminal information database 350. [ In other words, the environment information transmitted from the terminals A and B stored in the terminal information database 350 can be independently managed.

Through the independent environment information management, the environment information management unit determines whether the environment information transmitted from the specific user terminal is valid by comparing the environment information statistic value of the predetermined space with the environmental information value transmitted by the specific user terminal, It is possible to calculate the reliability of the image.

For example, when the carbon monoxide concentration value of the predetermined space having the tolerance range of 0.5 ppm is maintained at 5 ppm, if the carbon monoxide concentration value transmitted from the user terminal A is 5.3 ppm, the environment information management unit 340 The carbon monoxide concentration is included in the tolerance range and is determined to be effective environment information and can be used as environment information for updating the environment information database 360. On the other hand, when the carbon monoxide concentration value transmitted from the user terminal B is 8 ppm, The environment information database 360 may not update the carbon monoxide concentration because it is determined that the carbon monoxide concentration is out of the tolerance range and is not valid environmental information.

In addition, when the user terminal B continuously transmits the environment information out of the tolerance range, the environment information management unit 340 can reduce the reliability of the user terminal B and store it in the terminal information database 350. In this case, the use approval processing unit 320 can determine the priority of the user terminal based on the reliability of the user terminal stored in the terminal information database 350. [

However, the present invention is not limited to this, and when a majority of user terminals included in a predetermined space provide environment information exceeding the tolerance range, the environment information management unit 340 determines that there is a sudden change in environmental information, It is also possible to update the environment information database 360 based on the information.

According to an example, the environment information server 300 may be configured to determine whether the beacon terminal 200 is connected to the beacon terminal 200 based on at least any one of the number of user terminals connected to the beacon terminal 200, And a beacon signal controller (not shown) for adjusting the intensity, transmission period, and activation state of the transmitted beacon signal. For example, there may be one or more beacon terminals 200, one beacon terminal 200 relaying one user terminal and the environment information server 300, and one beacon terminal 200 having ten Comparing the case of relaying the environment information server 300 with the user terminal, the burden of the beacon terminal 200 may be larger in the latter case. In this case, the beacon signal controller (not shown) can reduce the relay burden between the user terminal and the environment information server 300 by changing one or more of the beacon terminals 200 from the standby state to the active state.

According to an example, the beacon signal transmission period may be initially designed to be 100 ms. If the beacon signal control unit requests permission to use the environment information of the user terminal included in the predetermined space, the beacon signal transmission period is set to 50 ms The environment information transmission delay can be reduced.

7 is a flowchart illustrating an environmental information management method according to an example. 7 may be an example of an environmental information management method performed by the environmental information management system 500. [

Referring to FIG. 7, the user terminal 100 and the environment information server 300 are capable of transmitting and receiving environmental information through the beacon terminal 200.

At least one beacon terminal 200 is installed in a range capable of communicating with the environment information management server and can relay the communication between the user terminal and the environment information server (701, 702).

According to an example, the beacon terminal periodically transmits a beacon signal to search 701 for a user terminal capable of communicating with the environment information server within the communication range of the beacon terminal.

The user terminal 100 may then detect 702 the transmitted beacon signal. For example, when a beacon signal is detected, the user terminal 100 may transmit the terminal information including the location information of the user terminal and / or the unique identification information of the user terminal to the environment information server 300 (702, 703). If the user terminal 100 can accurately estimate the position of the user terminal according to the reception sensitivity of the beacon signal, the user terminal 100 transmits the location information of the user terminal to the environment information server 300 through the beacon terminal 200, It is possible to transmit the location information of the beacon terminal 200 to the environment information server 300 when accurate position estimation is difficult.

Next, when the environment information server 300 receives the terminal information, the environment information server 300 generates an authentication key for authentication of the user terminal and transmits the authentication key to the user terminal (704, 705). It is also possible to generate a security code corresponding to the authentication key and the authentication key according to the security level of the environment information system 500, and transmit the generated authentication key to the user terminal.

The user terminal 100 may complete the authentication by receiving the authentication key via the beacon terminal 200 (705). However, according to the security level of the environment information system 500, the user terminal 100 may transmit the security code It is also possible to complete the authentication. In this case, the environment information server 300 generates the received security code and the authentication key, compares the generated security code and the generated security code, and if the security codes are identical to each other, determines that the authentication is valid and completes the authentication.

When the authentication is completed, the user terminal can request permission to use the collected environment information in the environment information server 300 (706). Here, the user terminal 100 can request the environment information collected in a predetermined space including the user terminal using the location of the user terminal, and can request the environment information of the specific space according to the setting of the user.

Next, the environment information server 300 can process the approval of the use of the environment information when the user terminal whose authentication has been completed receives the request to approve the use of the environment information. For example, when the authentication of the user terminal is completed by transmitting the authentication key to the authentication user terminal, the environment information server 300 can approve the use of the environment information according to the environmental information use approval request of the user terminal having the valid authority have.

If the use of the environment information is approved, the user terminal 100 may collect environment information and transmit the environment information to the environment information server through the beacon terminal 200 (707). By transmitting the environmental information collected by the user terminal, which has been approved by the user terminal to the authentication and use of the environment information, to the environment information server, it is possible to prevent the collection of the environment information without the user's consent, .

When the environment information server 300 receives the environment information collected from the user terminal 100, the environment information server 300 may update the stored environment information while storing the received environment information in the environment information database (708). Here, the update of the environment information may be to replace the stored environment information with the received environment information, and may be statistical information such as an average value of the environment information received for a predetermined time.

Next, the environment information server 300 may provide the updated environment information to the user terminal 100 through the beacon terminal 200 (709). For example, the environment information server 300 acquires environment information of a predetermined space in which a current user terminal is currently located from the environment information database without specifying any specific information based on the terminal information received from the user terminal, The environment information of the specific space requested by the user terminal may be acquired from the environment information database and provided to the user terminal.

When the environment information is received, the user terminal 100 may display the received environment information on the display of the user terminal (710). In addition, when receiving at least one environmental information, each environment information can be displayed by dividing the environment, and environment information can be displayed with different visibility according to a predetermined standard. For example, fine dust, ozone, and carbon monoxide concentration are divided into the following categories: "good" when the carbon monoxide concentration is 0 to 2 ppm, "normal" when the carbon monoxide concentration is 2.01 to 9 ppm, "poor" when the carbon monoxide concentration is 9.01 to 15 ppm, 'Very Poor', each of which can be displayed in different colors such as blue, green, yellow and red.

In addition, the user terminal is not limited to displaying environmental information, and may be provided to the user visually (e.g., display blinking on the information output unit), tactile (e.g., Vibration), and audible (e.g., ringing) notifications.

One aspect of the present invention may be embodied as computer readable code on a computer readable recording medium. The code and code segments implementing the above program can be easily deduced by a computer programmer in the field. A computer-readable recording medium may include any type of recording device that stores data that can be read by a computer system.
