Hereinafter, the configuration of the present invention will be described in detail with reference to the drawings.
For reference, all M2M (Machine-to-machine) described in the drawings can be interpreted as IoT (Internet of Things) in the present specification, and an event can be interpreted as an action throughout the specification.
Meanwhile, the term 'platform' used in the present specification has the same or very similar meaning as 'module' or 'component'.
As shown in FIG. 1, the IoT cloud service system 100 according to the present invention comprises an
The service platform (120)
1) a rule engine 221 'including a rule for the behavior of the IoT terminals, a rule
2) a device /
3) a dashboard 223 'configured to display the status of the system and a dashboard management module 223 configured to manage the dashboard,
4) a data service management module 224 configured to efficiently manage the data, and
5) a European Telecommunications Standards Institute (ETSI) interface management module 225 that provides server / terminal interface functionality based on an international standard.
On the other hand, the rule engine 221 'and the rule
Describing the functions performed by the rule engine 221 'in more detail, the rule engine divides the rule to be set by the user into three elements and constructs them. A rule consists of data (target data), condition (when agent) and target agent (what agent). Through the rule consisting of three elements rather than a simple rule, the condition and the target action used in each rule become independent from each other. In addition, various rules can be constructed through combinations.
For example, a plurality of thermometers (# 1, # 2...) Are installed in a certain place, and the rule here is that "when 13th thermometer is more than 20 degrees, send e-mail". In this case, if you look at the three elements of the rule, the '13th thermometer' is the target data, 'above 20 degrees temperature' is the when agent, and 'send email' . The goal action once used, 'Send e-mail', can be used again when creating other rules (ie, different temperature conditions of different thermometers, different temperature conditions of the same thermometer, etc.) What agent can be used different from 'mail transmission'.
One rule created with the above data, condition, and target behavior is extensible, which can be extended via virtual data. Virtual data is not physical and actual data coming from terminals (i.e., sensors), but is data that the user arbitrarily designates.
I will expand the example of the thermometer example above.
After defining the two-digit number as virtual data (A), if the temperature data transmitted from the thermometer is more than 30 degrees (Condition 1), change the tens digit of A to 1. If the humidity data transmitted by the hygrometer is more than 60% (Condition 2), change the number of digits of A to 1. In this case, a state of 11 based on the virtual data (A), that is, a discomfort index risk state, can be newly defined. Thus, by combining simple rules with virtual data, a new complex situation can be defined. The virtual data types utilized in this example can be changed depending on the problem to be solved. Such a process is illustrated in FIG. 10.
Real-time input data is transmitted through sensors (here, thermometers, hygrometers), and A is defined as virtual data (1010, 1020 and 1015).
Then, when the data for the situation is inputted and recognized, it is determined whether each criterion (temperature 30 degrees, humidity 60%) is satisfied (1030), and when the condition is satisfied, Change the position as defined above (Action, 1040).
Then, the virtual data A can be recognized as a situation in a behavior (What), and in this case, recognition and action by virtue of the
On the other hand, application of virtual data enables sequential situation propagation for specific situations, which can be reflected in the work progress process definition.
For example, if the value of the virtual data (a) is changed, if a plurality of rules reflecting this are registered, a large number of rules will be triggered in this situation. If the rule triggered here changes the value of the virtual data (A) again, a 'workflow extension configuration with periodicity' using this becomes possible.
For example, virtual data (B) indicating the degree of congestion is defined, and the value of the congestion virtual data (B) is increased as the degree of congestion increases. On the other hand, independently of this rule, when the congestion degree is 10 or more, a logic flow different from the existing logic flow can be generated through the rule of changing the congestion virtual data (B) to 0.
That is, at 1050, when the value of the virtual data A becomes equal to or higher than a predetermined level, it can be set to 0 again to have a periodicity that restarts at 1010 and 1020 (temperature 30 degrees and humidity 60%).
In this case, we can define multiple actions (What), return A to zero, and continue to flow in parallel without recognizing flows and periodicities.
On the other hand, the analysis platform 310,
1) a data visualization module 311 configured to visually display analyzed data,
2) a dynamic data handling module 213 that dynamically manipulates the data from the IoT terminals,
3) a report generation module 313 for reporting a result of analyzing the data,
4) a data
5) a data
The data
Big data can be used in the IoT cloud service of the present invention, although the DB and the equivalent storage for storing big data that store big data are not explicitly disclosed in the present specification and drawings.
In addition, the data
The real-time event processing by the rule engine and the real-time data analysis by the data stream analysis module occur in real-time, but the real-time data analysis by the data stream analysis module is similar to the real- As a further enhancement process, unlike real-time event processing, 'association analysis' makes it possible to perform much more complex analysis than event processing. Such a difference is obvious to a person skilled in the art of providing IoT service.
Specifically, there is a pattern-based normal / abnormal state judgment on time-series data as an example of real-time data analysis. There are cases where time series data has a certain pattern. For these patterns, we can derive clustering patterns. This derivation process is a 'supervised method' selected by the user and an 'unsupervised method' in which the system itself derives it by the clustering algorithm. Patterns derived from this process are classified into normal and abnormal patterns through screens provided by the system. In addition, regarding the abnormal pattern in terms of knowledge management, contents estimated as the cause of occurrence of each pattern are recorded by the user. This record is used to provide future analysis reports.
In order to determine the pattern of the real-time input data based on the pattern thus derived, the registered data table is referred to as a pattern map based on the time intervals at which the patterns are generated with respect to the previously derived patterns. The pattern matching with respect to the data to be input in real time based on the patterns registered in the pattern map is confirmed.
Specifically, a method of deriving a data set as a matching criterion is as follows. 2) derive inflection points for the moving average data; and 3) derive the data sets through the min / max values of the derived inflection point values.
The real-time pattern matching determination for the data sets thus derived proceeds according to the flowchart shown in FIG. The Kologorov-Smirnov test is used as an example to determine whether a match is made during the matching process, but other statistical methods may also be used.
Step 910 is a step of preparing a pattern list according to the length of time. In this list, as shown by
In
In
If there is no matching pattern in step 960 (i.e., the real time input data observed for 10 minutes is neither A pattern nor B pattern), then in step 950 a larger time period is selected than the current time , 20 minutes, a time period greater than 10 minutes, is selected for the next verification).
If the current time period is 20 minutes and the large time period is not in the list, the verification process is terminated. Otherwise, the verification process is continued according to the elapse of time (step 930).
After the event processing by the rule engine, an event processing report is generated. After analyzing the data
Although not explicitly shown in the figure, in each of the service platforms or the analysis platform, input data or processed data is stored in each of the configuration modules, that is, the service platform 220, 223 ', and it is evident that the analysis platform 310 can move between 311 and 315 as needed from time to time.
Meanwhile, in order to collect real-time sensor data input from the IoT terminals equipped with the IoT sensor and to use the real-time sensor data in the IoT service system 100, the

Then, it is determined which process is required for the data, which is determined as one of real time event processing, real time data analysis, or batch data analysis (step 520). The above decision is determined according to the type of data to be input, After that, the data is sent to the necessary place.
If it is determined that the real-time event processing is required data, the real-time event is input to the rule engine 221 '(step 530), and an event processing report is generated in the report generation module 313 (step 540)
