Output to the unit 320b and store. The sensor data transmitted by the plurality of sensors 100 is first received by the IoT service portal 200, and the sensor manager 220 of the IoT service portal 200 checks whether the sensor transmitting the sensor data is registered as a public sensor. Or, it is identified whether it is registered as a private sensor, and outputs to the sensor data collection unit 310 together with information indicating whether or not to be disclosed, and the sensor data collection unit 310, as described above, according to whether the sensor data is published or not The sensor data is stored in the data storage 320a or the private sensor data storage 320b.

The public sensor data storage unit 320a associates and stores publicly set sensor data input from the sensor data collection unit 310 with sensor information associated with a sensor measuring the public sensor data.

The private sensor data storage unit 320b stores private sensor data for each service. At this time, the private sensor data is not used for general purpose, but is sensor data used for a specific service of a service provider that has registered a sensor, and thus stored for each service.

The open sensor data analysis unit 330a stores the type of sensor data (fixed and mobile), detailed location information (room / outdoor, address, latitude, longitude), and sensor specification information (sensor product model, sensing information, and size information). Analyze sensor data values using each sensor information included, but generate statistical information by correlating various data such as daily / time, data type, location / place, etc. based on sensor environment information during statistical analysis The information is output to the open sensor data purification unit 340a.

The private sensor data analysis unit 330b statistically analyzes the private sensor data stored in the private sensor data storage 320b according to a service rule in which the private sensor data is to be used and classifies the private sensor data according to a service rule to generate analysis information to generate the private information. Output to the refiner 340b.

Referring to FIG. 3, a method for analyzing and providing IoT-based sensor data according to an exemplary embodiment of the present invention will be described. However, most of the functions performed in the IoT-based sensor data analysis and providing method to be described below are the same as the functions performed in the IoT-based sensor data analysis and providing system described with reference to FIGS. 1 and 2. In the following, the overall flow of the IoT-based sensor data analysis and providing method will be described.

First, the IoT service portal 200 receives sensor information about a plurality of mobile sensors 110 and a plurality of fixed sensors 120 respectively installed by service providers from the service providing server 400 to receive a sensor manager. In operation S301, the sensor data of the registered sensors may be determined whether the sensor data of the corresponding sensor is public or private (S303). The plurality of fixed sensors 120 are classified as open or closed and stored in the open sensor data storage 320a and the closed sensor data storage 320b, respectively (S306).

Thereafter, when sensor data is received from the plurality of sensors 100 (S311), the sensor manager 220 examines whether the corresponding sensor data is received from a public sensor or a private sensor (S313). When the sensor data is transmitted to the sensor data collector 310 of the IoT platform 300 along with information on whether the sensor is disclosed, the sensor data collector 310 may open the sensor data storage 320a according to whether the sensor data is disclosed. Alternatively, the sensor data is stored in the private sensor data storage 320b (S316).

In this case, in the case of the public sensor data, all the registration information related to the sensor data is stored together with the sensor data, and in the case of the private sensor data, the sensor data is stored for each service defined by the service providing server 400.

Thereafter, the public sensor data analyzer 330a and the private sensor data analyzer 330b analyze the sensor data stored in the public sensor data storage 320a and the private sensor data storage 320b to generate analysis information. (S320).

At this time, statistical sensor data is analyzed and analyzed according to each service rule for private sensor data, and statistical information is generated and classified as analysis information. For public sensor data, daily, hourly, Statistical information is generated as analysis information by analyzing correlations by data type, location, and place.

Thereafter, the open sensor data refining unit 340a checks the consistency of the data and checks outlier data of unnecessary data so as to generate a data analysis DB for each service type for analysis information on the open sensor data. By removing and refining the data suitable for the service, the private sensor data refining unit 340b checks the consistency of the data so as to be suitable for the corresponding service with respect to the analysis information on the private sensor data and outlier data of unnecessary data. Purify the data suitable for the service by removing the (S330).

Analysis information purified in step S330 are stored in the public sensor data analysis DB 350a and the private sensor data analysis DB 350b, respectively (S340).

Thereafter, when the service providing server 400 requests specific sensor data and analysis information, if the requested sensor data and analysis information relates to the public sensor data, the service providing server 400 transmits the data to the service providing server 400 and the private sensor. In the case of data, the sensor data and the analysis result are provided only to the service provider who registered the sensor (S350).

The invention can also be embodied as computer readable code on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, which are also implemented in the form of a carrier wave (for example, transmission over the Internet). It also includes. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.
