DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data analysis support device and a data analysis support method for supporting analysis of data collected and stored in a facility such as a building.

[0002]

2. Description of the Related Art Various facilities are provided in facilities such as high-rise buildings, apartment houses, hospitals and factories. For example, the equipment includes air-conditioning equipment, electric equipment, crime prevention equipment, disaster prevention equipment, heat source equipment, and the like, and these equipments are provided with a number of various devices.

In recent years, intelligent buildings and the like have been provided with a data analysis support device for assisting an operator in analyzing data. The data analysis support device operates the various devices (ON / OFF status of pump, ON / OFF of air conditioner).
/ OFF status, etc.), data collection means for periodically collecting data from various management points such as the environmental state (temperature and humidity, cold water supply temperature, air volume, water supply pressure, etc.) of the device, and this data collection means Data storage means for storing the collected data.

In this data analysis support apparatus, data stored in the data storage means is displayed on a screen as a graph such as a trend graph or a histogram in response to a request from an operator. These graphs are used for analysis of energy consumption, thermal environment evaluation, and air-conditioning control analysis. That is, it is used for various purposes such as confirmation of an operation state, confirmation of controllability, analysis of a cause of abnormality, and management of energy consumption.

[0005]

As for the graphs such as the trend graph and the histogram, a large number of graphs are prepared as standard functions assuming various situations as a system. The operator performs analysis by combining these graphs from the viewpoint of personal work. The combination of the graphs differs depending on the specialized field of the operator and the contents of work. In this case, the operator selects and specifies a desired graph and displays it on the screen. This graph is displayed by opening one window at a time. Here, if a large number of graphs are selected and designated, the number of windows becomes large, and some windows overlap. Therefore, operations such as changing and moving the size of the window must be frequently performed.

[0006] To prepare a large number of graphs,
Program development and engineering occurred, resulting in increased costs and increased engineering costs. Also, since the graphs required for analysis occupy a considerable amount of built-in weight, data can be compared, narrowed down, and details or overall views can be superimposed so that operators can easily use them. Expressing all functions such as watching, due to budget issues,
Very difficult.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to reduce the labor of an operator, to provide a number of graphs to be prepared, and to add functions to the graphs. An object of the present invention is to provide a data analysis support device capable of reducing the number of data analysis.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a matrix graph display means for displaying a graph of a currently opened window in a matrix on one screen, and a matrix graph display means. And a graph position changing means for changing the position of the graph in response to a user operation. According to the present invention, for example, if twelve windows are currently opened and graphs are displayed, the twelve graphs are displayed in a matrix on one screen. The position of the graph displayed in a matrix can be freely changed by, for example, a drag operation of a mouse. If the entire graph displayed in a matrix is saved as a graph matrix, the graph matrix can be called up on the screen as needed, and can be used repeatedly.
In other words, saving as a graph matrix not only reduces the number of graphs, but also lets you know not only the graphs used for analysis, but also the combinations of analysis and the order of analysis (story). ,
There is no need to narrow down the data in a fumbled state from the beginning.

Further, the present invention provides a compound condition storing means for storing compound conditions set on a screen, and checking accumulated data and, when the compound conditions are confirmed to be satisfied, the date of the compound condition establishment date. Is stored, and compound condition data display means for displaying at least one of the data and the graph of the compound condition on the compound condition day is provided. According to the present invention, if complex conditions such as a valve opening degree and an air supply temperature are set for the purpose of, for example, “confirming the state of the air conditioner at the time of the maximum air conditioning load”, the accumulated data becomes one day. Is automatically checked once to determine whether the composite condition is satisfied. If the establishment of the complex condition is confirmed, the date of the complex condition establishment date is stored.

The data analysis support device 1 transmits information (such as the ON / OFF status of the pump, the ON / OFF status of the air conditioner, the temperature / humidity, the cold water supply temperature, the air volume, and the water supply pressure) from various management points in the building to the controller 4 and the The data is periodically collected via the communication line LAN via the host controller 3. This data is collected by the CPU 1-1. The CPU 1-1 accumulates the collected data in the RAM 1-2 with the collection time.

[Graph Matrix] FIG. 3A is a view showing an example of an equipment operation support screen displayed on the display 1-7. A menu bar M is displayed on the equipment operation support screen GS. The menu bar M is provided with menu items such as “File”, “Image”, “Registration”, “History”, and “Window”. When you click on the "Window" with the mouse, pull-down menu M
1 and a graph name list M2 indicating the graph name of the currently opened window appear.

In this example, 12 graph names are shown in the graph name list M2, which indicates that 12 windows are currently open. The first window is “Pump System Trend”, the second window is “Pump Individual Trend”, the third window is “Pressure Status”, the fourth window is “Unit Control”, and the fifth The window is "Airline map", the sixth window is "Air conditioner A trend", ..., 1
It can be seen that each graph of “Air conditioner F trend” is displayed in the second window.

In the pull-down menu M1, "Alignment",
There are "No display", "Graph matrix (with comment)" and "Graph matrix (only graph)" items. Click "Graph matrix (with comment)" to display the currently opened window on one screen. Are displayed in a matrix. In this example, since twelve windows are open, twelve graphs are displayed in a matrix on one screen.

FIG. 3B shows a display example. When "Graph matrix (with comment)" of the pull-down menu M1 is clicked, a graph matrix screen GM appears, and cells # 1 to # 12 arranged in three columns and four columns are displayed.
Graph G1 of the 12 windows currently open in
To G12 are displayed. In the cells # 1 to # 12, comment columns C1 to C12 are provided below the graphs G1 to G12. In the comment columns C1 to C12, various comments such as points to be noted for each graph can be written to each graph when each graph is displayed.
When "Graph Matrix (Graph Only)" is clicked, the comment columns C1 to C12 appear in cells # 1 to # 12.
C12 is not provided.

The positions of cells # 1 to # 12 can be freely changed by dragging the mouse. That is, graphs (G1 to G12) displayed in a matrix form
Can be freely changed for each cell (# 1 to # 12). If the graph is interrupted, the existing graph is shifted to the right (the rightmost is the left end one step down). The source graph is packed. Unnecessary graphs can be hidden by right-clicking the mouse. The cells in the hidden graph are blank. If you drag another square to a blank square, fill the square without shifting the subsequent squares. You can also insert blank cells by right-clicking the mouse. Double-clicking on a graph enlarges the cell containing the graph.
In this example, the maximum number of graphs displayed in a matrix on one screen is 12, but it is needless to say that the number is not limited to 12.

A comment button BT1, a print button BT2, and a save button BT3 are provided on the graph matrix screen GM. When the comment button BT1 is clicked, a dialog D1 as shown in FIG. 4 appears, and from this dialog D1, various comments such as notes on the entire graph matrix can be freely written.
That is, cells # 1 to # 1 on which the graphs G1 to G12 are displayed.
The whole of # 12 is a graph matrix GRM, and various comments such as points to be noted when using the graph matrix GRM can be written.

When the print button BT2 is clicked, FIG.
The graph matrix GRM is printed as shown in FIG.
In this case, a comment written in the dialog D1 is added to the printed graph matrix GRM.

The comment written in is added.

In this embodiment, the operator
The analysis can proceed while viewing the graphs G1 to G12 displayed in a matrix on the graph matrix screen GM at a time. In this case, there are no graphs that cannot be seen because they overlap, and frequent operations such as changing or moving the size of the window are not required, and the labor of the operator is reduced. In addition, since it is possible to simultaneously compare a large number of graphs in one screen, it is not necessary to prepare a partially combined graph such as a graph C obtained by combining the graph A and the graph B, for example. Further, it is not necessary to add a function of superimposing the graph A and the graph B, and as a result, it is possible to reduce the number of graphs prepared as standard functions and the functions to be added to the graphs.

Further, in the present embodiment, the position of the graph in the graph matrix screen GM can be freely changed, and can be rearranged along the flow of time or rearranged along the flow of energy. It can be sorted so that it is easy to compare buildings or facilities.

The graph displayed in a matrix on the graph matrix screen GM can be freely determined by the operator. That is, if a window is opened by selecting and specifying a desired graph, the graph is displayed in a matrix on one screen. As a result, only graphs that are suitable for one's own specialty and business can be arranged in a matrix, and necessary graphs can be collected on one screen for analysis.

In this embodiment, graphs arranged in a matrix on one screen can be stored as a graph matrix GRM. Thus, the graph matrix GRM that has been used once can be called up on the screen as needed, and can be used repeatedly. The graph matrix GRM used once contains not only the graph used for the analysis, but also information such as the combination of the analysis and the order of the analysis. In addition, it is possible to refer to notes and the like entered in the comment column. As a result, there is no need to narrow down the data in a groping state from the beginning, and the labor of the operator is greatly reduced, and the analysis time is greatly reduced.

[Status History] In FIG. 3A, when "history" in the menu bar M is clicked, a pull-down menu M3 appears as shown in FIG. This menu M
3, when “Status History” is clicked, the analysis pattern list L1 in which the composite condition is set in “Condition Edit” described later
Appears. In this example, “air conditioner deterioration AHU-1”, “air conditioner deterioration AHU-2”, and “air conditioner deterioration AHU-3” are listed as analysis patterns. In addition,
The above-described graph matrix GRM can be called from “display history” in the bull-down menu M3.

When a desired analysis pattern is clicked in the list L1, a list of days when the compound condition set in the analysis pattern is satisfied (a compound condition satisfied day list)
L2 is displayed. When a desired day is clicked in the list L2, a list L3 of the data and the graph of the compound condition of the day appears. If "data" is clicked in this list L3, the data of the compound condition of the day is displayed. If "graph" is clicked, a graph (a graph including compound condition data of the day) specified in "condition editing" described later is newly opened and displayed.

[Condition Edit] In the pull-down menu M3,
Click "Edit Condition" to open the analysis pattern list L
4 appears. In this example, "air conditioner deterioration AHU-1", "air conditioner deterioration AHU-2", and "air conditioner deterioration AHU-3" are listed as analysis patterns. When "air conditioner deterioration AHU-1" is clicked in the list L4, a condition editing screen GA as shown in FIG. 8 appears. In this example, it is assumed that “air conditioner deterioration AHU-1” has already been listed as an analysis pattern in the list L4. Hereinafter, a case where “air conditioner deterioration AHU-1” is newly registered will be described. I do.

When newly registering "air conditioner deterioration AHU-1", a condition editing screen GA without an analysis pattern name is displayed, and this is set as a condition editing screen for "air conditioner deterioration AHU-1". . The condition editing screen GA is provided with a management point extraction / selection unit GA1. In this management point extraction / selection unit GA1, addresses, names,
Extract button BT4 by specifying unit, point type, etc.
When you click, a list of management points that match the specified conditions appears. From this point list, select the management point for which you want to set conditions.

A condition setting section GA2 is provided on the condition editing screen GA. In the condition setting unit GA2, data check conditions can be set for the management points selected by the management point extraction / selection unit GA1.
In this case, the data value of the selected management point is compared with a constant, the data value of the selected management point is compared with the data values of other management points, and a comparison condition expression (>, <, ≧,
≤, =, <>, etc.) can be selected and set as check conditions.

This check condition can be selected and set up to five management points selected by the management point extraction / selection unit GA1. The condition setting unit GA2 can set “AND” and “OR” conditions between the selected management points for which the conditions have been set. This "AND", "O
The check condition for the selection management point including the condition of "R" is a compound condition (extraction condition) of "air conditioner deterioration AHU-1"
It is said. The contents of the compound condition are displayed in the compound condition display section GA3.
Is displayed in the condition column S1. The composite condition display part GA3 is provided with a comment column S2, and specific condition contents can be entered in text.

The condition editing screen GA is provided with a display graph designation section GA4 and a purpose input section GA5. In the display graph designation section GA4, a graph name displayed when "graph" in the above-described list L3 is clicked is set. In the purpose input section GA5, the purpose achieved by checking the composite condition set on the condition editing screen GA is entered. In this case, "air conditioner deterioration AHU-1"
The purpose achieved by checking the complex conditions set in "1. Check the condition of the air conditioner at the maximum air conditioning load"
Write.

[Check of Compound Condition] The CPU 1-1
Once a day, the stored data automatically stored in the RAM 1-2 is automatically checked, and the analysis patterns (“air conditioner deterioration AHU-1”, “air conditioner”) created by “condition editing” in the pull-down menu M3 are checked. It is confirmed whether or not the compound condition set in “air conditioner deterioration AHU-2” and “air conditioner deterioration AHU-3” is satisfied. If the establishment of the complex condition is confirmed, the date of the complex condition establishment date is stored for each analysis pattern. The stored compound condition satisfaction date is a list L2 of “state history”.
Reflected in. The check of the stored data may be performed manually.

Thus, the operator can access the RAM 1-2.
Even if you do not analyze all the data stored in the list, you can select the list L1 from the "status history" of the pull-down menu M3.
By selecting L2 → L3, it is possible to see the data and graph of the composite condition on the date when the composite condition of the desired analysis pattern is satisfied. As a result, the analysis of the relationship between the operating load and the failure can be performed without taking much time, and the labor of the operator can be reduced. In addition, since detailed analysis can be performed by setting the composite condition, the number of graphs prepared as standard functions and the functions to be added to the graphs can be reduced as a result.

When the user clicks "Fill" on the menu bar M on the equipment operation support screen GA (see FIG. 9), up to ten recent display graphs are displayed in a pull-down menu. Thus, the operator can select a graph and display it on the screen without following the hierarchy from a menu (not shown) having a tree structure. Clicking on "image" displays a menu for shifting to a system diagram or layout diagram of the equipment.

The setting items required for displaying the graph, for example, the display period, display unit, digit alignment, and management points can be changed online, and are filtered according to weekdays, holidays, days of the week, times, and the like. Data analysis can be performed according to the operation time and period.

In "Registration", a model menu is prepared in advance as a sample. It is possible to create a user menu based on this model menu. It is also possible to register the displayed graph in the model menu or the user menu by copying and pasting. In addition, a menu can be created according to the system diagram of the equipment, and the menu can be individually managed for each login user. For example, a user can create a menu of analysis procedures and equipment classifications of his / her attention. As a result, an analyst can construct a menu by himself or herself, depending on the energy flow or the equipment system at one site, thereby greatly reducing the manpower for system customization (engineering).

In the above-described embodiment, it has been described that the accumulated data in the RAM 1-2 collected periodically is analyzed. However, such collected data can be backed up / restored. Through a network, a similar analysis method can be applied at a later date or at another location. Batch data can be batch-checked for past or another site (equipment) data that has been backed up.

As is apparent from the above description, according to the present invention, matrix graph display means for displaying a graph of a currently open window in a matrix on one screen, and matrix display. A graph position changing means for changing the position of the graph in accordance with a user operation is provided.
In addition, the analysis can be performed while rearranging the graph in a convenient manner such as the analysis order. This eliminates the need for frequent operations such as changing or moving the window size, thereby reducing the operator's labor. Further, since a large number of graphs can be simultaneously compared in one screen, it is also possible to reduce the number of graphs prepared as standard functions and the functions to be added to the graphs. In addition, such as the combination of analysis and the order of analysis,
Analysis can be performed while creating a story with multiple graphs. If the entire graph displayed in a matrix is saved as a graph matrix, not only can the number of graphs be reduced, but also the graphs used for analysis,
It is possible to know the combination of the analysis and the order of the analysis, and it is not necessary to narrow down the data in a groping state from the beginning, so that the operator's labor is greatly reduced and the analysis time is greatly reduced.
