FIG. 1is a block diagram of a table generation apparatus that implements a data display method for an energy management system, according to an embodiment of the present invention.

Referring toFIG. 1, a table generation apparatus100according to an embodiment of the present invention may be included in a control system, such as an energy management system, or a monitoring system that monitors data acquired from the control system.

The database110stores data received from a data acquisition and management system such as an energy management system or a Supervisory Control and Data Acquisition (can be abbreviated as SCADA) system. Also, the database110may include a tabular form using the data, table generation data based on the tabular form, and data for a sorting method.

As a user interface of the table generation apparatus100, the user input unit120provides a means that enables a user to input a table display request signal for data which is received from a data acquisition and management system such as the energy management system and is stored in the database110.

Moreover, in response to manipulation of a user, the user input unit120may input a table generation item for table display, and in detail, the user input unit120may be configured with a key switch or a touch switch. The user may input, for example, various items such as a tabular form, a table to be generated, and a layer through the user input unit120. In particular, in response to manipulation of the user, the user input unit120may input a data sorting method in a table display form at a time when a table is generated or at a time when the table is displayed.

The table generation unit130generates the data, stored in the database110, into a table according to control by the control unit150, based on a table generation item which is input through the user input unit120. The table generation unit130may generate a repetition table or a hierarchical table according to a tabular form request which is input through the user input unit120.

In generating the repetition table, the table generation unit130may generate a table so that data included in an input table are listed widthwise or lengthwise. Based on user input information which is input through the user input unit120, the table generation unit130may supply a data sorting form to the control unit150so as to change and display a data sorting form in generating a table or in displaying the table.

The display unit140displays a table generated by the table generation unit130according to control by the control unit150. In particular, based on an input from the user input unit120, the display unit140may display the table, generated by the table generation unit130, in a predetermined form and a sorting form according to control by the control unit150.

The control unit150may receive a table generation request signal which is input through the user input unit120, and in response to the table generation request signal, the control unit150may control the table generation unit130so as to generate a table, based on the table generation item which is input through the user input unit120. Also, the control unit150may control the display unit140in order for the display unit140to display the table generated by the table generation unit130. Also, in generating or displaying a table, the control unit50may receive user request information about a data sorting form which is input through the user input unit120, and control the table generation unit130and the display unit140so as to re-sort and display data in a sorting form corresponding to the user request information.

A data display method for an energy management system according to an embodiment of the present invention will be described in detail with reference toFIGS. 2 to 16, based on a configuration of the table generation apparatus that is a means for executing the data display method for the energy management system according to an embodiment of the present invention.

FIG. 2is a flowchart illustrating a repetition table display operation according to an embodiment of the present invention, andFIGS. 3 and 4are exemplary diagrams for describing a form value input for generating a repetition table displayed according to an embodiment of the present invention.

Referring toFIGS. 2 to 4, in step S202, the control unit150receives a table generation request signal which is input through the user input unit120according to manipulation of a user. The table generation request signal may be generated by the selective manipulation of the user based on a separate input request menu, or as illustrated inFIG. 3, when the user selects a layer310which is displayed by default on a table display screen, the table generation request signal may be generated in response to the user selection. The control unit150may control the display unit140so as to enter a table generation menu in response to the table generation request signal.

Therefore, in response to the table generation request signal, as illustrated inFIG. 3, the control unit150may control the display unit140so as to display a table generation window310(S204).

The control unit150may receive a new table addition request signal which is input through the user input unit120according to manipulation of the user based on the table generation window310, and receive information data (hereinafter simply referred to as data) having a new tabular form. The new table addition request signal, as illustrated inFIG. 3, may be generated by menu selection for addition of a menu. In step S206, the control unit150may receive data (see a touch switch region referred to by reference numeral311inFIG. 3) of a name and a form of a table which is to be generated based on the table generation window310.

When the data of the tabular form is receives in step S206, the control unit150may receive a base key value312of a table which is to be generated in step S208. Here, the base key value may be a data name of the table which is to be generated. Also, when the user set a form of a table to a repetition table, the control unit150may receive, from the user input unit120, data about a display form for an opening direction and the number of lines of a table (see a touch switch region referred to by reference numeral313inFIG. 3).

In step S210, the control unit150may receive setting data of a repetition table from the user input unit120. In step S212, the control unit150may receive, from the user input unit120, data having various sorting forms based on an alphabetical order or a reverse alphabetical order as information about a table which is to be generated.

When an input of condition information of a generated table is completed in step S214, the control unit150may read corresponding setting input data in step S216, and command the table generation unit130to generate a table based on the corresponding setting input data in step S218. Also, in step S220, the control unit150may control the display unit140so as to display the table generated by the table generation unit130.

That is, the control unit150may control the display unit140so as to display data of a table on the basis of a sorting method (i.e., the alphabetical order) which is set as illustrated inFIG. 4(see a display region referred to by reference numeral400inFIG. 4), based on various table generation condition input information which is input as illustrated inFIG. 3.

FIG. 5is a flowchart illustrating a data sorting operation of a repetition table according to an embodiment of the present invention, andFIGS. 6 and 7are exemplary diagrams for describing a data sorting operation of a repetition table according to an embodiment of the present invention.

In a step S502of a repetition table display mode where a repetition table which is generated as illustrated inFIGS. 3 and 4according to an operation ofFIG. 2, a repetition table is displayed as illustrated inFIG. 6, the control unit150according to an embodiment of the present invention may receive a selection signal input of a sorting menu window (see a display region referred to by reference numeral610inFIG. 6) in step S504. A display operation based on selection of a sorting menu may be executed in response to a lower popup window input in a table display window or an input in a separate menu screen.

When the user selects a sorting menu through the user input unit120, in order for the user to select a selection window (see reference numeral611inFIG. 6) of a sorting mode from the sorting menu, the control unit150may control the display unit140so as to display the selection window611of the sorting mode.

When the user selects the selection window611of the sorting mode as illustrated inFIG. 6, the control unit150may re-sort and display data of a table (i.e., re-sort and display the data in the reverse alphabetical order) as illustrated inFIG. 7(see a re-sorted table700inFIG. 7), based on the selected sorting mode.FIG. 7illustrates a screen display example of the display unit140, and in particular,FIG. 7illustrates that data of a displayed table is changed from a sorting mode of the alphabetical order to a sorting mode of the reverse alphabetical order, and is displayed. In addition, data of a displayed table may be displayed based on various sorting modes. The various sorting modes include various sorting conditions about an alphabetical order/reverse alphabetical order alphabet of an initial phoneme, digits, or a time sequence of input data.

FIG. 8is a flowchart illustrating a hierarchical table display operation according to an embodiment of the present invention, andFIGS. 9 and 10are exemplary diagrams for describing a hierarchical table display operation according to an embodiment of the present invention.

Referring toFIGS. 8 to 10, in step S802, the control unit150according to an embodiment of the present invention receives a table generation request signal from the user input unit120according to manipulation of a user. When the user touches and selects a layer930displayed by default in a separate request menu screen (not shown) or a table setting display screen as illustrated inFIG. 9, a table generation request signal may be generated by the user input unit120, and the control unit150may control the display unit140so as to enter a table generation menu in response to the table generation request signal.

That is, in step S804, the control unit150may control the display unit140so as to display a table generation window as illustrated inFIG. 9in response to the table generation request signal.

In step S806, the control unit150may receive a new table addition request signal, which is generated by the use's touch in the table generation window, from the user input unit120, and receive an input of new tabular form selection data from the user input unit120. The new table addition request signal, as illustrated inFIG. 9, may be generated by an input based on a touch (see a selection bar in which “addition” is put inFIG. 9). The table generation window may include an item selection region (see reference numeral900), which enables the user to select and input a name and a form of a table, and a selection region (see reference numeral920) that enables the user to select and input a sorting reference of the table. As illustrated inFIG. 9, an operation of generating a hierarchical table will be described as an example.

When a form setting of a table is completed, the control unit150may receive a base key value which is a data name of table input by manipulation of the user input unit120(i.e., a touch switch) by the user (S808), and moreover receive data of tables which are to be generated as a hierarchical table input by manipulation of the user input unit120by the user.

The control unit150may receive, from the user input unit120, selection data of a plurality of tables included in the hierarchical table for generating the hierarchical table. That is, in step S810, the control unit150receives a first hierarchical table, which is to be displayed as an uppermost layer of the hierarchical table, from the user input unit120. Here, as illustrated inFIG. 9, the first hierarchical table is an item which is to be displayed as an uppermost hierarchical table in a measurement layer information window910, and the uppermost hierarchical table may be selected by the user and may be transferred to the control unit150by the user input unit120.

Subsequently, similarly to an input of the first hierarchical table, the control unit150may receive a table input of a second layer, which is a lower layer of a first layer, from the user input unit120in step S812. In step S812, as illustrated inFIG. 10, the control unit180may receive a second hierarchical table from the user input unit120according to selection of the user which is performed through a measurement layer information window1010. Subsequently, in step S814, the control unit180may receive a third layer table from the user input unit120according to selection of the user.

When an input of a plurality of hierarchical tables is completed, as illustrated inFIGS. 9 and 10, the control unit150may receive, from the user input unit120, an input of selection data (see a window referred to by reference numeral920inFIG. 9and a window referred to by reference numeral1020inFIG. 10) of the user for a sorting reference of each of the first layer and the second layer in step S816.

When a setting input is completed, the control unit150may read a completed setting form and data in step S820, control the table generation unit130so as to generate a table having a hierarchical form in step S822, and control the display unit140so as to display the generated table in step S824.

FIG. 11is a flowchart for describing a data sorting operation of a repetition table according to an embodiment of the present invention, andFIGS. 12 to 16are exemplary diagrams for describing a data sorting operation of a repetition table according to an embodiment of the present invention.

The present embodiment will be described in detail with reference toFIGS. 11 to 16. In step S1102, as shown in the operations ofFIGS. 8 to 10according to an embodiment of the present invention and an exemplary diagram, a hierarchical table display mode may be performed in which the display unit140displays a hierarchical table generated by the table generation unit130according to control by the control unit150as illustrated inFIG. 12.

FIG. 12illustrates hierarchical tables of two groups, and each of the two groups includes a plurality of first hierarchical tables1211and1212and a plurality of second hierarchical tables1221and1222.

The control unit150, as illustrated inFIG. 13, may receive a selection input of a sorting mode for one of a first layer and a second layer. That is, as illustrated inFIG. 13, when a user selects a sorting menu for data of a first hierarchical table through a popup window1300in step S1104, and then selects a sorting mode (i.e., one of ascending sorting of descending sorting) from a sorting mode display window1310included in the sorting menu in step S1106, the control unit150may receive, from the user input unit120, sorting request data of the first hierarchical table and selection data (i.e., data of a descending sorting mode) of the sorting mode included in the sorting menu.

When one of various sorting modes such as ascending sorting and descending sorting is selected, as illustrated inFIG. 14, the control unit150may re-sort and display the first hierarchical table1212of each group, based on the selected sorting mode in step S1108. In this case, data of the table1222of second to Nth layers corresponding to a lower layer of the first layer may be moved in interlocking with the re-sorted first layer.

In step S1110, the control unit150may determine whether a sorting menu of the second hierarchical table1222is selected by the user and is input from the user input unit120, in a state where data of a first hierarchical table are re-stored and displayed. As illustrated inFIG. 15, when selection of a sorting menu for data of the second hierarchical table1222which is selected by the user through a menu window1500is input, and then the user selects a sorting mode (i.e., one of ascending soring of descending sorting) from a sorting mode display window1510included in the sorting menu in step S1112, the control unit150may receive, from the user input unit120, sorting request data of the second hierarchical table and selection data (i.e., data of an ascending sorting mode) of the sorting mode included in the sorting menu.

The control unit150may re-sort data of a second hierarchical table on the basis of the selected sorting mode in step S1114, and as illustrated inFIG. 16, may display the re-sorted data in the display unit140in step S116. Re-sorting of the second layer may be limited to data of the second hierarchical table included in one first layer, and the second layer is sorted separately from data of another first layer.

As described above, according to the embodiments of the present invention, since it is not required to edit separate data for a data table, a reoperation of a system is not needed.

Moreover, according to the embodiments of the present invention, a user interface which matches a user's requirement can be provided, and thus, a table display form can be easily changed, thereby increasing the use convenience of the user.
