TECHNICAL FIELD [0001] The present invention relates to a service collision arbitration method,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a technology related to the Internet of Things (IoT), and more particularly, to a method of resolving conflicts that may occur when a thing Internet device provides a service.

Currently, the use and configuration of Internet devices are mostly tailored to specific individual users. In other words, there are many cases in which the object Internet device operates according to a preference or state of a specific user to provide a service.

However, the environment in which we live is not limited to a personal space, and there are more spaces that many people use in common. Object Internet devices operating in this common space may experience conflicts of operation in operating to provide services.

1 is a view showing an example of occurrence of collision of IoT air conditioner operation system. 1 shows an IoT air conditioner for detecting a user and setting a room temperature according to a user's preferred temperature. And there are users A and B who have authority to use IoT air conditioner.

The IoT air conditioner senses user A and sets the temperature to 25 degrees according to user A's preference. After a while user B is additionally detected, and user B has a preferred temperature of 20 degrees. In this case, the IoT air conditioner faces the question of whether to change the temperature to 20 degrees or to maintain the existing value of 25 degrees.

Fig. 2 is a diagram showing an example of occurrence of IoT lamp operation type collision. In Fig. 2, there is an IoT lamp that operates by sensing the entrance and exit of the user. There are users A and B who have authority to use IoT lights.

User A first turns on the IoT lamp to enter and sleep. After a while, user B enters. In this case, the IoT lamp faces the question of whether it should be lit or kept off.

Currently, most of the Internet devices are set to operate in response to the final state without regard to the above situation. Various conflict resolution algorithms can be applied to resolve a situation where a service provision conflict occurs due to such an operation, but these algorithms are not suitable for limited resource use of complex or object Internet devices Data is often requested, which is difficult to apply.

It is an object of the present invention to provide a method and system for resolving conflicts in a method of providing a user service by introducing an arbitration process to an object Internet device.

In the detecting step, it is possible to detect whether a service conflict occurs by changing the resource set value.

The generating step may include generating a set resource value to be used for conflict resolution if the resource set value agreed by the service users is already stored for the purpose of resolving the service conflict.

The generating step may further include generating a resource setting value for a user having a higher priority in the conflict resolution when the agreed resource setting value does not exist.

The generating step may further include generating a predetermined resource setting value and an arbitration value of the changed resource setting value into the conflict resolution if generation of the conflict resolution according to the priority order is not possible.

And, the determining step may include determining execution of the conflict resolution if there is no user to be harmed by the generated conflict resolution.

The determining step may further include, when there is a user who is to be harmed by the generated conflict resolution, determining execution of the conflict resolution based on permission of the user to be damaged.

According to another aspect of the present invention, there is provided a computer-readable recording medium having recorded thereon a program for causing a computer to execute: detecting that a service conflict occurs; If an occurrence of a service conflict is detected, identifying a plurality of elements and generating a conflict resolution; And a step of determining execution of the conflict resolving step, wherein a program capable of performing the service conflict arbitration method is recorded.

2. Service conflict mediation

FIG. 5 is a flowchart illustrating a service conflict arbitration method of a destination Internet device according to an embodiment of the present invention. The service conflict arbitration method according to an exemplary embodiment of the present invention performs arbitration by analyzing a complex element such as a pre-agreement between users of the Internet devices, priority of users, and criticality of a situation.

To this end, as shown in FIG. 5, first, it is detected whether a service collision occurs (S210). It is a process of determining whether a conflict occurs with a resource value to be set / changed for providing a service.

If the occurrence of a service conflict is detected in step S210, a complex solution is identified / evaluated to generate a conflict resolution (S220). In order to generate a conflict resolution, the pre-agreement between users and priorities of users are analyzed / evaluated based on predetermined criteria.

Next, it is finally determined whether to execute the collision solution created in step S220 (S230). In the final decision, the criticality of the situation is taken into account and the notification / consent of the user may be required.

In the following, each step will be described in more detail.

3. Collision detection

The collision detection step S210 shown in Fig. 5 will be described in detail with reference to Fig. 6 is a detailed flowchart of the collision detecting step S210.

6, it is detected whether the sensing result of the sensor 110 corresponds to a predetermined trigger triggering condition (S211). If the trigger triggering condition is satisfied (S212-Y) It is confirmed whether the resource setting value for control should be changed from a preset value (S213).

If it is not necessary to change the resource setting value in step S213 (S213-N). It is re-executed from the step S211. On the other hand, if it is determined in step S213 that the resource setting value should be changed (S213-Y). A conflict resolution creation step S220 is performed.

Here, it is assumed that the resource setting change causes a service conflict. If the resource set value does not cause a service conflict due to a slight change, step S211 may be performed instead of step S220.

4. Create a conflict resolution

The collision resolution generation step (S220) shown in FIG. 5 will be described in detail with reference to FIG. 7 is a detailed flowchart of the conflict resolution generation step (S220).

As shown in FIG. 7, in order to resolve a conflict, if a resource set value previously agreed by the service users for the service conflict resolution has been stored (S221-Y), the resource set value is generated in the conflict resolution S222).

If there is no pre-agreed resource set value (S221-N), it is checked whether priority of users is different (S223). If the priority of the users is different (S223-Y), the resource setting value for the user with the highest priority is generated in the conflict resolution (S224).

On the other hand, if the priorities of the users are not defined or all are equal (S223-N), it is impossible to generate a conflict resolution according to the priorities. In this case, an arbitration value of the predetermined resource setting value and the changed resource setting value is generated in the conflict resolution (S225).

As the arbitration value, the average value, the median value, and other representative values of the predetermined resource setting value and the changed resource setting value can be applied.

The final decision step S230 is then performed for the generated conflict resolution.

5. Final decision

The final decision step S230 shown in FIG. 5 will be described in detail with reference to FIG. 8 is a detailed flowchart of the final decision step S230.

As shown in FIG. 8, first, a threshold for collision resolution generated in step S220 is checked (S231). The criticality check is to check whether there is a user to be damaged by conflict resolution.

For example, if a user has a lot of heat, the temperature is set too low, or if there is a sleeping user, lighting may be turned on to see if sleeping is interrupted.

If it is determined that there is no user to be damaged by the conflict resolution created in step S220 (S232-Y), the final determination is made to execute the conflict resolution (S233).

On the other hand, if there is a user to be harmed by the conflict resolution created in step S220 (S232-N), an additional procedure such as agreement / notification of the conflict resolution is performed for the user to be damaged (S234) (S233).
