Description
The present invention relates to a system for processing physical hardware (gateway equipment, sensors, etc.), even if the data input originates from a third server or an external platform other than the physical H / W, This is about technology that allows you to do that.
The IoT system has the advantage that more information can be obtained as more objects are sensed, as the name of the thing Internet tells.
Therefore, the IoT system generally collects sensor data by installing all sensors physically. However, it is almost impossible to collect data by attaching sensors to all objects, which does not simply mean physical impossibility. There are a lot of service platforms where the infrastructure is already installed and services are provided in the form of Open API based on this. There is no need to install sensors separately in these service platforms or open APIs.
However, at present, the data generated by the service providing the data using the Open API can not be used, and the data itself can not be accessed if the communication protocol between the IoT platforms is different.
Therefore, there is a need for a technique that uses data generated from each of the above cases in correspondence with each of the above cases.
Therefore, the present invention provides a method by which the above-mentioned Open API or protocol can use data provided through a different service platform.
The method for receiving data from the Open API using the virtual gateway in the object Internet system according to the present invention includes: searching for an external Open API; creating and registering a virtual gateway, a virtual device or a virtual sensor corresponding to the retrieved Open API; And receiving information via the virtual gateway.
The method may further include displaying the received information.
A method for receiving data from an external object Internet system using a virtual gateway in a object Internet system according to the present invention comprises the steps of: searching the external object Internet system; searching for a protocol used by the retrieved external object Internet system; Generating and registering a virtual gateway, a virtual device, or a virtual sensor corresponding to the external object Internet system using the analyzed protocol of the external object Internet system, and receiving information through the virtual gateway . ≪ / RTI >
The protocol analyzing step may include searching a database in the object Internet system to search for information about the protocol or using the object Internet system in a predetermined place on a network to search for information about the protocol Lt; / RTI >
The method may further include storing the retrieved protocol information in the database after retrieving the protocol information on the network.
The object Internet system may further include a step of requesting protocol analysis information from another object Internet system or an object Internet system requesting data transmission from another object Internet system.
According to the present invention, not only physical hardware (gateway / sensor) but also virtual data such as weather information can be provided together with the Open API when providing IoT service, Since it can interoperate with the platform, more sensing is possible, and it is possible to expand the profit model by providing a richer service.

The present invention provides a method for receiving data in an IoT system (object Internet system).
Hereinafter, the present invention will be described with reference to the drawings.
1 is a conceptual diagram of a general IoT (object Internet) system. The IoT
A detailed description of the
FIG. 2 shows a concept of an IoT system and a data collection and dissemination API that is installed and operated independently from the system. The Open API (Open Application Programming Interface) 120 is an interface installed and operated independently from the
In order to explain the present invention, the
As shown in FIG. 2, the Open API 120 is implemented separately from the
That is, it is most natural for the user of the IoT system to provide the UI as shown in FIG. 6, which displays the system in an environment almost the same as the IoT system environment shown in FIG.
3 is a conceptual diagram illustrating a result of providing the Open API to another gateway (virtual gateway) by the IoT system according to the present invention. That is, an API existing outside the system provides a method of accessing sensors connected to the outside through a virtual G / W (virtual gateway) only and not allowing access to another system using a completely different interface Is the main technical constitution of the present invention.
In order to provide the above method, the IoT system can search the API that is currently providing services on the network. This search may be specified in advance or may be performed through a data mining technique.
It is possible to automatically select a similar service category provided by the current IoT system among the searched target APIs and to display it to the user or to display all the searched API services to the user and to select a necessary one of them.
When the search process is completed, the creation and registration steps of the virtual gateway are performed. This process is also performed by the IoT system.
That is, the user receives the input through the gateway and device registration screen as shown in FIG. 7, and registers the virtual gateway and the virtual device / sensor information through the input. The term virtual is used here because this information is not from the sensors attached to the IoT system but from the API provided by the newly implemented gateway.
At this time, since the format of the Open API is already known, it is necessary to prepare such a known format in advance, or to store the format in the internal DB, and to convert data of a format suitable for each API.
In the case of FIG. 7, for example, an API providing humidity, precipitation probability, rainfall, temperature, wind speed, 7, more information can be transmitted to the target API, but only the information of the (virtual) sensor selected according to the user's needs is used.
The steps of receiving the information about the designated sensors and displaying the data screen received from the original IoT system and the data transmitted from the newly registered virtual sensors in the step of displaying this information to the user are shown in Figs. 5 and 6 However, since it is a user interface, everything except the virtual sensor type can be changed.
4, it may be possible to use not only the Open API but also data received by a
In this case, after the step of automatically or manually searching the IoT system to be used, a step of analyzing the protocol used by the retrieved IoT system is performed.
Let's take a closer look at this analysis step.
The protocol of the known relative IoT system through the search can be stored in the internal DB once. Thereafter, the protocol can be analyzed through the protocol information provided from the public safe area, or it can be determined whether it is one of many protocols (already known in the analysis method) stored in the internal DB , Or similarity measure, and then stores the acquired information in the internal DB, and analyzes the relative protocol through the captured contents, thereby reading the necessary information.
At this time, if the analysis method is known, it is possible to grasp 100% of the data of the partner system, but otherwise, the data may not be grasped partially.
Meanwhile, the IoT system according to the present invention can receive a protocol analysis information request or a data transmission request from another IoT system. If protocol analysis information is requested, protocol analysis information of the IoT system that sent the request is requested, And the protocol analysis information stored in the DB can be exchanged. In the case of a data transmission request, it can be accepted or rejected, and such acknowledgment / rejection can be performed automatically or manually.
If the protocol information can not be grasped, the user can be requested to input the information or the location of the corresponding information.
After this step, a process of creating and registering the virtual gateway / virtual device / virtual sensor is performed, and this process has already been described above, and detailed description will be omitted.
Thereafter, the step of receiving the data and displaying the received data has already been described.
According to the present invention as described above, the IoT system, which was able to display only limited data to the user by using its own sensors in a closed manner, can use data of an existing external data source or other external IoT system together, And double / triple check of inaccurate data.
It is clear that this effect of the present invention has significant data representation capabilities for a conventional IoT system that receives data only from sensors installed to be connected to it.
