At this time, data mining is a classification that classifies data based on similarity without classification or classification that predicts a class of new data by learning a training data set in which a class is known by searching for an implicit relationship between preprocessed data ( Clustering) can be performed.

Of course, in addition, various mining methods may exist, and may be mined differently depending on the type of big data collected and stored or the type of query to be requested later. The big data constructed in this way may be verified through artificial neural network deep learning or machine learning.

At this time, a convolutional neural network (CNN) structure may be used for the artificial neural network. CNN is a network structure using a convolutional layer and is suitable for image processing, and classifies an image based on characteristics in the image by inputting image data. Because it can.

In addition, text mining is a technology aimed at extracting and processing useful information based on natural language processing technology from non / semi-structured text data. Through text mining technology, it is possible to extract meaningful information from a large bunch of text, grasp the linkage with other information, find categories of text, or get more than just searching for information. Using this, in one embodiment of the present invention, a large-scale language resource, statistical and regular algorithms may be used to analyze an identifier or natural language inputted into a query and discover hidden information therein.

In addition, the integrated control management server 120 may perform a schedule dynamic energy simulation of control systems installed in the internal structure, external structure, internal and external structures of the building.

For example, the schedule dynamic energy simulation is a result of predicting indoor and outdoor loads in a building and energy flow according to a load schedule.

Here, the indoor load includes the arrangement density, the number of occupants, the lighting density, and the device density of the first terminal for each compartment space, where the number of materials refers to the number of people who work or reside indoors, and the lighting density is the compartment space. Refers to the density of installed lighting, and the device density may mean the density of devices such as computers and copiers provided indoors.

In addition, the schedule includes, for each compartment space, an occupancy schedule, a lighting schedule, a device schedule, an air conditioning schedule, and an invasion schedule. The occupancy schedule refers to a schedule in a time period when people are in the room, and the lighting schedule lights up the room. It means the schedule of the time zone, and the device schedule refers to the schedule of the power-on temperature of the devices in the room, and the air conditioning schedule refers to the schedule of the operating time of the air conditioner or heater in the room.

The simulation unit can be EnergyPlus, ESP-r, TRYNSYS, etc., which can sufficiently simulate the physical phenomena occurring in a building. If the error between the simulation model and the real is large, the accuracy of the simulation through the calibration technique You can also improve

If the simulation example of the simulation unit is described in detail, two or more types of predetermined data having a correlation among the collected sensing information and security information (entry information) are selected.

For example, among various types of sensing information, only data of types of “air-conditioner fan air flow” and “air-conditioner fan power” may be selected. Of course, there is no limit to the type selected. Next, outliers are removed by applying a data filtering technique. It is preferable that the data filtering technique is a RANSAC technique. After data filtering, an approximate model is constructed using the data from which outliers have been removed. It is preferable to apply a Gaussian process to the construction method. Next, by constructing a predictive model using the constructed approximation model, it is possible to predict by simulating other types of data even if only one type of data is secured. For example, data for the air conditioner fan power may be predicted even if only the air conditioner fan air volume data is secured.
