Hereinafter, the present invention will be described in more detail with reference to the drawings.

1 is a diagram illustrating an M2M system to which the present invention is applicable. The M2M system to which the present invention is applicable collects the location and state information of the drone 10 moving at high speed, the integrated controller 40 controls the drone 10 based on this, and the learning server 50 is interested It is a system for tracking objects.

The M2M system to which the present invention is applicable is, as shown in FIG. 1 , a drone 10, a camera 20, a Lidar sensor 30, an M2M platform 100, an integrated controller 40, and a learning server 50 is built including

The drone 10 transmits its location information and status information to the M2M platform 100 in real time while flying in the sky.

The camera 20 and the lidar sensor 30 are devices installed in the drone 10 , and generate image data and sensor data and transmit them to the M2M platform 100 in real time.

The integrated controller 40 is a system for controlling the operation of the drone 10 based on data collected/stored in the M2M platform 100 or data received from the M2M platform 100 .

The learning server 50 is a server for learning an artificial intelligence model for automatically recognizing and tracking an object using data collected/stored in the M2M platform 100 or data transmitted from the M2M platform 100 .

In FIG. 2, the structure of a resource built in the M2M platform 100 shown in FIG. 1 is shown.

As shown in FIG. 2 , a <Drone> resource, which is a data resource for storing data generated by the drone 10, is created in the M2M platform 100, and the <Drone> resource includes an <ObjTracking> resource and a <Control> resource. > The resource has been created.

The <ObjTracking> resource is data generated by the drone 10 and is a resource in which data to be transmitted to the learning server 50 is stored, and the <Control> resource is data generated by the drone 10 and is transmitted to the integrated controller 40 It is a resource in which data to be transmitted is stored.

<Retarget> resource is created in <ObjTracking> resource and <Control> resource, respectively. The <Retarget> resource is a resource for re-delivering data received as its parent resource to the target URI without saving it in the resource.

In FIG. 2 , the data of the drone 10 targeting the <ObjTracking> resource is not stored in the M2M platform 100 by the <Retarget> resource, but is re-delivered to the learning server 50 conceptually. indicated.

That is, the resource structure shown in FIG. 2 corresponds to a resource structure for supporting delivery of data of the drone 10 to the learning server 50 via the data without being stored in the M2M platform 100 .

The "Target URI" attribute of the <Retarget> resource contains the address to which the data to be delivered should be re-delivered.

On the other hand, you can set the value of the condition under which re-delivery is performed as the "Filter" attribute value of the <Retarget> resource.

For example, as shown in FIG. 3 , when the Filter Condition is set to “All”, all data requested by the drone 10 to be generated is sent to the target address (learning server 50 in FIG. 3). retransmit

As another example, as shown in FIG. 3 , when the Filter Condition is set to “Data value > 50”, only the target address ( In FIG. 4, it is re-delivered to the learning server 50).

For data of 50 or less, the M2M platform 100 can be implemented to be discarded, but it is also possible to implement to be stored in the M2M platform 100 if necessary.

5 shows a case where the target address is the integrated controller 40 and the Filter Condition is set to “All”. In this case, as shown, the drone 10 re-delivers all of the data requested to be generated to the integrated controller 40 .

Thereby, the large-capacity batch data generated by the drone 10 is re-delivered to the target based on an event without storing it in the M2M platform 100, thereby reducing the load generation and real-time processing difficulties due to the M2M platform storing a large amount of data. be able to solve

In the above embodiment, it is assumed that a data creation message is received and notified from the drone 10, and in the case of other messages, such as an Update message or a Delete message, this Of course, the technical idea of the invention may be applied.

Furthermore, in FIG. 3 , it is assumed that the retransmission target for the integrated controller 40 and the learning server 50 is only the data of the drone 10 , which is only an example for convenience of understanding and explanation. Even when the data of the camera 20 or the lidar sensor 30 is transmitted back to the integrated controller 40 and the learning server 50, the technical idea of the present invention can be applied.
