Description

How to set up IoT / M2M system through usage analysis

The present invention relates to a technology for providing an automation function, and more particularly, to the automatic use of the devices used in the Internet of Things, intelligent things communication environment.

Things used in the Internet of Things (IoT) and Machine-to-Machine (M2M) systems incorporate sensors and network functionality. This enables a variety of services by allowing the device to acquire peripheral information and to exchange the acquired information with each other, or to transmit to other systems through a local network or an Internet connection. IoT / M2M can be applied to various fields such as home automation, wearable, smart vehicles, facility management, disaster prevention and energy management.

Many IoT / M2M systems are currently on the market, but are not yet very active. There are many reasons, such as unified specifications and expensive prices, but one of them is the inconvenience of management and configuration. When IoT / M2M systems are deployed in homes, offices, buildings, or on specific sites, at least dozens, hundreds, and thousands of devices are installed. It is very cumbersome for an administrator to manually register and set up individual devices, and may be impossible if the number of individuals is large. Also, in a home environment, non-expert members of the public may want to use the system, making configuration and management more difficult.

Discovering installed IoT / M2M devices and verifying the functionality provided is possible with self-configuration techniques such as zero-configuration, but using and interlocking the installed devices can be difficult. This can be cumbersome or difficult.

The present invention has been made to solve the above problems, an object of the present invention, to generate an operation profile through the analysis of the user's use behavior or pattern for the devices installed in the IoT / M2M environment, The system can be operated by automatically applying the created operation profile.

In addition, another object of the present invention is to present the generated operational profile to the user so that the user can directly review and modify the profile to apply to the system.

A system control method according to an embodiment of the present invention for achieving the above object comprises: a first searching step of searching for operation profiles in which the same trigger event and occurrence time zone match when a trigger event occurs; A second search step of searching for a management profile to which additional information matches among the management profiles searched for in the first search step; A third search step of searching for an operation profile including the most control event if the operation profile matching the additional information is not found in the second search step; And executing a control event according to the operation profile searched in the second search step or the third search step.

The system control method according to an embodiment of the present invention may generate a new operation profile based on the generated trigger event and the generation time zone when the operation profile in which the same trigger event and the occurrence time zone are not found is searched in the first search step. Generating step; may further include.

In addition, the system control method according to an embodiment of the present invention may further include adding the control event to the new operation profile when a control event occurs within a predetermined time.

In addition, the system control method according to an embodiment of the present invention, after the execution step, the step of monitoring an additional control event by the user; And generating a new operation profile including the additionally generated control event when the control event additionally occurs.

In addition, the system control method according to an embodiment of the present invention comprises the steps of comparing the generated new operation profile with the pre-stored operation profiles; If there is a pre-stored operation profile in which the same trigger event, occurrence time zone and control event match, updating additional information of the pre-stored operation profile; And deleting the generated new operation profile.

The system control method according to an embodiment of the present invention may further include updating additional information of the executed operation profile when a control event does not occur.

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

1. Operational Profile

In a typical IoT / M2M environment, devices with various sensors, actuators, and communication devices are installed, and these devices are managed through gateway equipment. The gateway monitors and collects events for devices registered to it.

In the embodiment of the present invention, the system event is divided into two types, a "trigger event" automatically generated by the detection of the sensor and a "control event" generated by the user's manipulation.

The operation profile proposed in the embodiment of the present invention is generated in the form of an "if ... then ..." conditional sentence, and the "if" portion includes one or more "trigger events" and "occurrence time", then The part consists of "control events".

In addition, it consists of "additional information" for determining whether to apply a profile. Operational profile generation and management according to user usage behavior monitoring is performed in the gateway device.

2. Create production profile

Operational profile generation according to the user's usage behavior monitoring is performed through the following process, as shown in FIG. 1 is a flowchart provided to explain a process of creating a new operation profile by event detection.

When an event occurs, it is checked whether the type of the corresponding event is a "trigger event" (S110). In the case of "trigger event" (S110-Yes), check whether "Profile ID generation Flag" is set (S120). "Profile ID generation Flag" indicates whether a new profile is created. Initially the "Profile ID Generation Flag" is set to 1 (flag set).

When the "profile ID generation flag" is set (S120-Yes), a new profile ID is generated so as to be distinguishable from other profiles (S130), and the "profile ID generation flag" is set to 0 (flag clear).

Next, an IF statement is formed based on the "trigger event" that occurred, and a "continuous event recording timer" is used to associate and record a control event that can occur after the trigger event has occurred (form a THEN statement). Drive (S140).

On the other hand, as shown in FIG. 2, if no control event occurs (ie, there is no THEN statement) before the timer times out, the profile being recorded is deleted, and if a control event occurs (ie, THEN statement is If so, the profile being recorded is stored (S200).

If a control event occurs (S110-No), and the "profile ID generation Flag" is 0 (that is, timer valid) (S150-Yes), the event is added to the THEN statement and the profile is updated (S160).

Before the THEN statement is formed (S110-Yes and S120-No), if a trigger event occurs continuously (S170-No), the IF statement is updated as a compound trigger event (S180).

When the profile is completed (S190), other information, such as the day of the week, is also recorded in the profile as "side information".

Through the above process, the adjacent trigger events and control events are grouped into one unique operation profile.

3. Management Profile Management / Application

Management of the operation profile according to the usage behavior of the user is performed through the process illustrated in FIG. 3. 3 is a flowchart provided to explain the operational profile management and application process.

When the trigger event occurs, the existing stored management profiles are searched for (S305). If no profile matching the same trigger event condition and time is found (S310-No or S325-No), a new operation profile is generated by event detection (S315). The process of creating a new operation profile has been described in detail with reference to FIGS. 1 and 2.

When profiles matching the trigger and generation time zones are found (S310-Y and S325-Yes), a profile matching the additional information is found (S330). If a profile matching the additional information is found (S335-Yes), the corresponding profile is executed (S340).

On the other hand, if the additional information does not match (S335-No), the operation profile with a large number of control events is selected and performed (S345). After performing the profile, the " continuous event recording timer " is driven (S350). If an additional control event occurs by the user before the timer times out (S355-Yes), a new operation profile is generated according to the event recording (S360), and there will be the same performance control event sequence compared to the existing stored operation profiles. If so, the additional information is updated (S365).

If the control event does not occur before the timer times out (S355-No), the additional information of the performed profile is updated (S370).

4. Example of use

4.1. Example # 1

The user installs the system and does not create a separate operating rule. The system is configured to automatically create and apply operational rules by default. The system analyzes the events that occur and creates, records and applies operational profiles according to the user's system usage patterns.

For example, at 9 am on Monday, the system detects that the entry and exit sensor is activated (trigger condition), the lamp is turned on within 5 minutes (continuous event timeout time), the air conditioner is turned on and the temperature is set at 25 degrees. In this regard, it is searched if there is a profile related to "Access In Event". If the relevant profile does not exist, create and save a new profile (Profile A: Entry In Event, 9:10 am → Light On, Air Conditioner (On, 25 degrees); Additional Information: Monday).

If the entry / exit sensor is activated on Tuesday at 9:05 am, the system searches for a profile for "entry-in event" and finds Profile A. Then, it is checked whether or not the generated "access in event" is in the allowable time zone of Profile A (9 AM ± 10 minutes), and the profile is executed. If the user does not take any action within 5 minutes for auto-executed actions (light on, air conditioner (on 25 degrees)), the profile information is updated (Profile A: Entry In Event, 9 am). ± 10 minutes → Lamp On, air conditioner (On, 25 degrees); additional information: Monday, Tuesday).

Due to the same conditions on Wednesday, when Profile A is run, if the user walks an additional blind within 5 minutes, a new profile will be created (Profile B: In and Out Event, 9 am ± 10 am → Light On, Air Conditioner (On, 25 degrees). ), Walking blind; additional information: Wednesday).

When the "entry in event" occurs on Thursday at 9 am, the system finds two profiles (Profiles A and B) that have the same trigger condition. Check the additional information in both profiles to see if there is a day of the week. If there are no days of the week, run the one with the highest number of events in the two profiles (Profile B). If the user does not take any further action, Profile B will be updated (Profile B: In and Out Event, 9 am ± 10 am → Light On, Air Conditioner (On, 25 degrees), Blind Walk; Additional Information: Wednesday, Thursday) .

If after 9 am the "Access In Event" occurs on Friday, if the user lowers the blind within 5 minutes of Profile B execution, the system detects that the related event sequence is the same as the existing Profile A and updates Profile A (Profile A). : In and out event, 9 ± 10 am → Light On, Air Conditioner (On, 25 degrees); Additional Information: Monday, Tuesday, Friday).

After 9am "Access In Event" on Monday, check that there are two applicable profiles but "Monday" is displayed in the additional information of Profile A and execute Profile A. After executing Profile A, if the user sets the air conditioner temperature to 20 degrees within 5 minutes, try to modify the profile. If there is only Monday in Profile A's additional information, we'll modify the temperature to 20 degrees in Profile A's configuration information, but other days are also added to Profile A's additional information. Create a profile (Profile C: In and Out event, 9:10 am → light on, air conditioner (On, 20 degrees); additional information: Monday).

4.2. Example # 2

The administrator sets the basic interlocking function through the system setting. The administrator sets the system to "operation rule recommendations state". The system collects the user usage patterns that occur and creates a profile. Provide administrators with operational profiles collected at specified intervals (daily, weekly or monthly) and time. At this time, the occurrence time, period, etc. of the newly created profiles are analyzed. In addition, the degree of similarity is analyzed by comparing with the profile used in the system.

Administrators can review the collected operational profiles and analysis information and apply them to the system after applying or modifying them (adding / deleting events or adding exceptions). If the administrator does not review the profile within the specified time, the profiles are continuously accumulated or the collected profiles are deleted and collected again according to the setting.
