METHOD AND SERVER FOR PROVIDING ENVIRONMENT INFORMATION BASED ON USER MOVEMENT}

The present invention relates to a method and a server for providing environment information according to a user's movement, and to a method and a server for providing highly analyzed environment information with respect to an area a user enters.

In order to enjoy a pleasant and safe life, interest in the environment in which people live is increasing, and accordingly, information on indoor and outdoor environmental conditions, for example, various environmental conditions based on information such as dust concentration, temperature and humidity, carbon dioxide concentration, etc. Techniques for monitoring contamination status are continuously being developed. Accordingly, it has become easier to monitor the pollution of the environment based on the acquisition of various information about the surrounding environment.

Environmental sensors that general users can carry are widely developed, and a technology for collecting and analyzing environmental information in a centralized manner and providing them to users has also been developed.

However, if the sensing sensitivity of the environmental sensor carried by the user is reduced or the reliability is lowered, the user has no choice but to obtain low-reliability information. There was a problem in that it did not properly reflect the environment of the region in which it is located.

Accordingly, there is a need for a technology that enables a user to receive environment information of a current location with high reliability.

An object of the present invention is to solve the problems of the prior art, and to provide highly reliable environmental information.

Although not shown in FIG. 3 , when there is a large floating population or a large area in each of the sub-regions S1 to S3 , the corresponding sub-regions S1 to S3 may be additionally divided into sub-concept areas.

The geographic area partitioning unit 210 may store geographic information partitioned by itself or by an administrator.

Referring back to FIG. 2 , the environment information collection unit 220 according to an embodiment receives environment information and location information of the current user terminal 100 from a plurality of user terminals 100 .

Since the location information of the user terminal 100 is received together with the environment information, the environment information collection / provision server 200 can collect the environment information for each area (A1 to A3) or sub-area (S1 to S3) do.

The environment information analyzer 230 according to an embodiment collects environment information for each area A1 to A3 and sub-area S1 to S3 based on the environment information and location information received by the environment information collection unit 220 . Analyze.

For example, the environment information received from the user terminal 100 is collected for each area A1 to A3, and a representative value of the values collected for each area A1 to A3 or sub-area S1 to S3 (eg For example, the average value) can be calculated.

According to an embodiment, the representative value of the environment information for each sub-region S1 to S3 may be calculated as follows.

Also, k is an environment information value received from each user terminal 100, and α is a weight applied to each environment information value.

The weight may be applied relatively high to the environment information value transmitted from the user terminal 100 with a high frequency of transmitting the environment information. In addition, when the difference between the value of the environment information transmitted in the past and the representative value calculated according to the above equation is less than the threshold range, a relatively high weight may be applied to the value of the environment information received from the user terminal 100 . there is.

That is, the representative value M may be calculated by applying a high weight to the environmental information value transmitted from the user terminal 100 that transmits the highly reliable environment information.

Meanwhile, the representative value of the environment information may be calculated for each area A1 to A3 including the plurality of sub areas S1 to S3 .

According to an embodiment, the representative value of the environment information for each area A1 to A3 may be equally calculated by Equation 1, or may be calculated according to Equation 2 below.

β is a weight applied to a representative value of environmental information for each sub-region S1 to S3. For example, the more the sub-regions S1 to S3 with a larger number of collected environmental information, the more the weight applied to the representative value of the environment information. can grow larger

Since the reliability of the representative value calculated based on a larger number of information is high, a high weight is given to the representative value of the environment information in the sub-regions S1 to S3 having high reliability.

The environment information providing unit 240 according to an embodiment is a user terminal 100 that newly enters each area A1 to A3 or sub-area S1 to S3 to the corresponding area A1 to A3 or sub-area S1. to S3) performs a function of transmitting the representative value of the environment information.

A representative value of the most recently calculated environment information may be transmitted. Also, since the user terminal 100 enters the third area A3 from the second area A2 , the representative environment information for the third area A3 may also be transmitted.

Meanwhile, when the user terminal 100 moves from the second sub-area S2 to the third sub-area S3 in the second area A2 (in case b), the environment for the second area A2 is The representative value of the information may not be transmitted, but only the representative value of the environment information for the third sub-area S3 of the second area A2 may be transmitted to the user terminal 100 .

In this way, by transmitting and receiving only necessary information between the server 200 and the user terminal 100, efficient information transmission/reception is possible, and communication traffic can be optimized accordingly.
