Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "electrically connected" with another part in between . Also, when an element is referred to as "comprising ", it means that it can include other elements as well, without departing from the other elements unless specifically stated otherwise.

1 is a block diagram showing a configuration of a plant field data processing apparatus according to an embodiment of the present invention.

1, a plant field data processing apparatus 100 according to an embodiment of the present invention includes a field data collecting unit 110, a field data analyzing unit 120, a field data database 130, And a field data providing unit 140.

The field data collection unit 110 collects field data in real time from at least one type of unit facility system (for example, a 'instrumentation / measurement system') included on the plant facility to which the present invention is applied. For reference, the field data may be various kinds of data collected from the on-site unit facility systems in the plant facility environment, for example, various kinds of data related to the performance, failure, and repair of the product. 1, field data collecting unit 110 receives field data from a plurality of kinds of plant unit system 10, respectively.

At this time, the field data collection unit 110 receives the field data through the interface corresponding to each unit facility system. For example, the field data collection unit 110 may collect field data from each unit facility system through an interface according to a TCP / IP scheme or a web service scheme.

The field data analyzing unit 120 detects the collected field data according to a preset pattern for each unit facility system, and analyzes the field data for each pattern to distinguish the valid data and the invalid data. The field data analysis unit 120 processes the field data divided into the valid data according to predetermined conditions and stores the processed field data in the field data database 140.

Specifically, the field data analyzer 120 analyzes the field data of each pattern based on the 'state analysis rule' stored in its own storage or in a separate storage unit (not shown). At this time, the state analysis rule may be an effective range criterion set for the field data value for each unit facility system. For reference, the condition analysis rules can be changed dynamically according to the conditions and conditions of the plant facility environment. For example, the change of the state analysis rule can be changed by updating the state analysis rule for each pattern previously stored in the field data analysis unit 120 itself or in a separate storage unit (not shown) with a new state analysis rule. This allows field data to be analyzed according to new conditions without changing the plant installation system itself.

The field data analyzing unit 120 judges field data having a value out of the valid range criteria as a result of the analysis based on the state analysis rule among the collected field data as invalid data. Then, the field data analysis unit 120 determines that an abnormal situation has occurred in the unit facility system that transmitted the field data determined to be invalid data. Then, the field data analysis unit 120 updates the facility identification information and the status information (i.e., 'abnormal state') for the unit facility system determined to have generated an abnormal situation (for example, ) And stores them in the field data database 130.

On the other hand, the field data analyzing unit 120 judges the field data having the value included in the valid range reference as the valid data, based on the analysis result of the collected field data based on the state analysis rule. Then, the field data analysis unit 120 processes field data for each pattern determined as valid data according to a preset processing standard.

Specifically, the plant field data processing apparatus 100 collects continuous field data for each of a plurality of unit facility systems, and stores field data every predetermined time unit. At this time, the shorter the time unit for storing the field data and the more all the received field data are stored, the higher the accuracy of the field data used for subsequent processing (for example, plant facility analysis, monitoring, reporting, and the like). However, as the time unit for storing the field data is short and the amount of the field data to be stored is large, the load on the system is increased and the processing speed is slowed, which may result in lack of promptness.

Accordingly, the field data analyzing unit 120 calculates a maximum value, a minimum value, and an average value of the collected field data by collecting the field data for each pattern for each set unit period (for example, in units of seconds) And stores it in the data database 130. That is, the field data analyzing unit 120 processes the continuous field data within the unit time into the maximum value, the minimum value, and the average value, and stores the processed field data.

For example, FIG. 2 is a diagram for explaining a processing method of field data according to an embodiment of the present invention.

In FIG. 2 (a), continuous values of field data according to time (sec) are shown.

2 (b), the field data analyzing unit 120 divides the input field data in units of seconds and calculates a minimum value, a maximum value, and an average value Average).

2B, the minimum value of the continuous field data is' 2.7 ', the maximum value is' 3.2', and the average value is 2.95 'in a unit interval from 0 second to 1 second . That is, according to such processing, continuous field data having an analog form can be expressed in a digital form having a plurality of specific values in units of seconds as shown in FIG. 2 (c).

The field data database 130 stores the processed field data output from the field data analysis unit 120 in a predetermined storage manner.

Specifically, the field data database 130 stores field data of big data by applying a NoSQL (Not Only SQL) method, which is a non-relational database structure. In other words, by using NoSQL which is capable of load distribution and large capacity storage through a distributed structure, not all field data is stored in a standardized table, but a key of field data and a data value (vlaue) can be stored and matched. At this time, since the NoSQL method does not support the function of processing and outputting data, the field data is inserted in accordance with the output format in the beginning.

For example, FIG. 3 illustrates a method of storing and processing field data according to an embodiment of the present invention.

The field data database 130 implements various output formats (i.e., field data alignment types) in a materialization view. In FIG. 3, it is shown that the data is stored in a unique key view of stored field data.

Referring back to FIG. 1, the field data providing unit 140 receives a request for specific field data from an external processing system (indicated as 'plant facility management / monitoring system 20' in FIG. 1). The field data providing unit 140 inquires the materialized view according to the request type among the materialized views stored in the field data database 130 to detect the field data. The field data providing unit 140 provides the detected field data to the external processing system.

Hereinafter, a field data processing method of the plant field data processing apparatus 100 according to an embodiment of the present invention will be described in detail with reference to FIGS. 4 and 5. FIG.

Then, the collected field data is detected and the continuous field data for each unit facility system is collected (S420).

Then, the collected field data is analyzed according to a predetermined state analysis rule (S430).

Specifically, the validity range criterion is compared according to the value of the collected field data and the state analysis rule corresponding to the pattern. If the value of the field data is out of the valid range criterion, it is determined that the data is invalid data. It is determined that the data is valid data.

As a result of the analysis, it is determined whether the collected field data is invalid field data (S440).

At this time, if the collected field data is valid field data instead of invalid field data, the continuous field data is processed according to predetermined conditions (S451).

At this time, the processing condition may be set to calculate the maximum value, the minimum value and the average value of the continuous field data included in the predetermined time unit.

Then, the processed field data is stored in the field data database 130 (S461), and the materialized view for the corresponding processed field data is stored (S462). In addition, state information (hereinafter referred to as " facility information ") of the facility that has transmitted the corresponding field data (i.e., unit facility system) is stored (S463).

At this time, the processed field data can be stored in the field data database 130 in the NoSQL method.

On the other hand, if the collected field data is invalid field data, the state of the unit facility system that transmitted the corresponding field data is set to an abnormal state (S452).

Then, the abnormality status information (i.e., 'facility information') of the relevant monetary system is stored (S463).

For reference, the equipment information stored in step S463 includes information such as equipment specifications, installation information (location, etc.), equipment status (normal or abnormal), and the like.

At this time, the external processing system may be various processing systems for monitoring / managing the unit facility systems on the plant facility, analyzing the status of each unit facility system, and monitoring / reporting the field data.

Then, a refinement view corresponding to the request type among the refinement views previously stored in the field data database 130 is inquired (S520).

Then, the field data according to the inquired refinement view is detected and provided to the external processing system (S530).

5 illustrates an example in which plant facility management / monitoring, facility status analysis, and field data monitoring / reporting operations are performed in various external processing systems after step S530.
