Description

  The present invention relates to a device data display apparatus and a device data display method for displaying values of time series data collected from a plurality of devices.

  A power information monitoring system that collects power information from devices connected to a network and monitors the power information is known. In this system, for example, the power consumption (unit: watt-hour, etc.) and the index indicating the behavior of the equipment that affects the power consumption are collected sequentially from the devices connected to the network such as routers and computers via the network. To do. For example, the index indicating the behavior of the router is the traffic amount (unit: bit per second, etc.) of the network router. In addition, the system stores or collects information such as input devices such as a keyboard and mouse for the user to perform screen operations, a display device that displays collected indexes, and network addresses of information collection destination devices. A data storage unit is provided for recording the consumed power amount and an index indicating the behavior of the device that affects the consumed power amount.

  For example, the user confirms the power consumption trend from the power consumption, analyzes the behavior of each device from the device behavior index, and compares the analyzed behavior with the power consumption to generate unnecessary power consumption. Narrow down the factors that are being used. For this purpose, the user visually compares the indicators representing the time-series behavior of each device in the form of line graphs and superimposed. In order to narrow down the cause of the problem from the shape of the plotted graph, for example, the following work is performed.

  (1) Extracting the same model that differs in behavior from other devices. For example, according to the graph shown in FIG. 14, “device 1”, “device 2”, and “device 3” have the same model, but only “device 2” consumes a large amount of power.

  (2) Extract unusual behavior that occurred in a specific device at a specific time zone. For example, according to the graph shown in FIG. 14, it can be seen that only the transition of “2010/06/03” is different from other days in the “lunch break” time zone of “device 3”.

  Embodiments of an apparatus data display device according to the present invention will be described below.

  FIG. 1 is a block diagram showing a configuration in which a device data display device according to the present invention is applied to a power information monitoring device.

  As shown in FIG. 1, the power information monitoring apparatus 1 collects time series data such as power consumption from a plurality of devices (“device 1”, “device 2”,...) Via a network 3. Means 11 and display means 12 for displaying the values of the time-series data collected by the collecting means 11 on the display device 2. The power information monitoring apparatus 1 also includes an enlargement / reduction operation accepting unit 13, a display time designation accepting unit 14, a display form designation accepting unit 15, and a device designation accepting unit 16 that accept designation of a display mode by the display unit 12.

  The collection unit 11 sequentially collects time-series data such as power consumption from a plurality of devices (“device 1”, “device 2”,...) Via the network 3 and stores them in the data storage unit 11A.

  The collection means 11 refers to the network address and collection cycle stored in the device definition information of each device (“device 1”, “device 2”,...), And determines the behavior index value and consumption of the device from the device group. For example, the amount of electric power is acquired at regular intervals. The acquired power consumption, the behavior index value of the device, and the like are added with power consuming device information indicating the date, time of acquisition, and acquisition source, and stored in the data storage unit 11A as time series data.

  The display unit 12 displays a display screen on the display device 2 using the time series data stored in the data storage unit 11A. The calculation unit 12a of the display unit 12 performs calculations for sequentially creating display contents according to various instructions from the user, which will be described later, and the display contents are displayed by the display unit 12.

  2 is a diagram illustrating a display screen by the display means 12, FIG. 3 is a diagram illustrating a zone diagram of the display screen, and FIG. 4 is a diagram illustrating a level threshold.

  As shown in FIGS. 2 and 3, the display screen of the display means 12 is associated with, for example, devices (“device 1”, “device 2”,...) In the vertical direction and times in the horizontal direction. A zone diagram 50 in which the rectangular regions 51, 51,.

  In the zone diagram 50, an index value of each index selected in accordance with an operation on the list box 52 in a certain device is color-coded according to the level value, and an icon (stored in advance) having a different shape, color, pattern, or the like according to the level value. Or a rectangle whose luminance is changed according to the level value. By using a display method in a matrix format in which these are arranged in a horizontal row along the time series and further vertically arranged for each device, it is possible to display a list of time series changes of indices in each device for all devices.

  Here, the level value is a numerical value obtained by determining the meaning of the index value in several stages. Levels have different meanings depending on the indicators, such as those representing a mere amount of quantity and those representing good or bad. The level determination method is determined in advance according to the property of the index and the characteristics of the user environment. In the example shown in FIGS. 3 and 4, the index value is determined by a level threshold value. Here, the power consumption is selected as the index value, and the power consumption in the corresponding device and time zone is displayed as the display color of the rectangular area 51 in each rectangular area 51.

  The user can select an arbitrary index value from various time-series data stored in the data storage unit 11 </ b> A by operating the list box 52 and display it in the zone diagram 50.

  The area 53 of the display screen shows the relationship between the index value and the display color of each rectangular area 51. In the example shown in FIGS. 3 and 4, the power consumption is divided into five levels according to the level threshold, and a specific display color is assigned to each level. In the example of FIG. 2, “20”, “40”, “60”, and “95” are set as level thresholds, and level values 1 to 5 are assigned to each level in ascending order of numerical values.

  The display magnification in the vertical direction of the zone diagram on the display screen 50 can be changed according to the user's operation on the enlargement / reduction operation accepting means 13. Images according to the display magnification are sequentially created by calculation in the calculation unit 12a of the display means 12, and are reflected in the display by the display means 12.

  At the minimum magnification, one pixel can be set as the vertical width of the rectangular area 51 for the display pixel. In this case, for example, if the display screen has a resolution of 1600 × 1200 pixels, the index value of more than 1000 devices Can be displayed at once. FIG. 2 shows a display example for 12 vehicles.

  In addition, the display magnification is always set so that the vertical width of the rectangular area 51 is an integral multiple of the display pixel, and the same number of display lines are assigned to each rectangular area 51, thereby making each rectangular area 51 clear. In addition, it may be capable of displaying with an accurate display color.

  When the display magnification is reduced, it is not possible to accurately grasp the correspondence between the display position and the device on the screen, but it is possible to visually recognize the presence of a device that shows a different tendency from other devices on the reduced screen. it can. Therefore, by enlarging a necessary portion, for example, a device having a problem can be specified.

By the way, it is possible that the state of an apparatus changes in connection with a user's social activity. For example, the power consumption of the device is small in the early morning on weekdays, but large in the daytime on weekdays.
Here, the zone diagram in FIG. 3 is effective in that the time series data of a large number of devices can be viewed. However, since the zone diagram in FIG. 3 only represents the state of each device along the time axis, it is difficult to find the relationship between the state of the device and the social activity of the user.
On the other hand, in the device data display device according to the present invention, the zone diagram of FIG. 3 for each predetermined time zone defined by the user's designation received by the display means 12 via the display time designation receiving means 14. Is separated. Thereby, the apparatus data display apparatus which concerns on this invention can grasp | ascertain the relationship between the behavior of an apparatus and a user's social activity based on the time slot | zone defined by the user.

Specifically, the definition of a predetermined time zone for dividing the zone diagram by the user's specification is performed as follows.
The setting of the time axis (horizontal axis) in the zone diagram follows the user's designation through the display time designation receiving means 14. Week, day, hour, minute, etc. can be selected as the unit of time zone length in the zone diagram (for example, set to one day unit to define the relationship with the user's social activities). The setting contents are stored in the display information storage unit 12A as “time zone definition data”.

  In addition, time series data representing the behavior of the device is further displayed in the time zone for one unit (for example, in units of one day) displayed in the zone diagram according to the designation by the user via the display time designation receiving means 14. Week, day, hour, minute, etc. can be selected as the unit of the time zone (for example, even if it is set to display the behavior of the device every 8 hours in consideration of the user's daily social activities) Good). The setting contents are stored in the display information storage unit 12A as “second time zone definition data”.

  FIG. 5 shows an example in which Monday is divided into early morning, daytime, and nighttime. FIG. 6 shows a setting screen for accepting designation of a time zone and the like. The user can freely set the time zone displayed as a zone diagram by operating the setting screen as shown in FIG. As shown in FIG. 6, the contents of the time zone stored as the time zone definition data are displayed in the area 56a of the setting screen. In the area 56b, the input of the attribute of each time zone is accepted, and the addition and deletion of each time zone can be performed by the add button 56c and the delete button 56d. Input of attributes and addition / deletion of time zones are reflected in the display of the area 56a and also in the zone diagram of FIG. In the zone diagram 50 of FIG. 5, the zone diagrams for each designated time zone are displayed in a state of being separated from each other according to the setting contents on the setting screen. .. Are displayed on the display fields 54, 54,..., That is, the time zone information of each zone diagram.

  Furthermore, a new time zone can be set by an operation on the zone diagram.

  FIG. 7 is a diagram illustrating an example of creating a desired combination of time zones. For example, as shown in FIG. 7, the display means 12 creates a zone diagram in which data for only the daytime on Monday is collected by performing an operation of selecting only the daytime on Monday from the zone diagram. As described above, the device data display device of the present invention extracts only the index values in the time zone specified by the user from the index values in each device, and specifies them by arranging them in a horizontal row in time series. It is possible to display a list of time-series changes of indices in each device only for the designated time zone.

  Note that the device data display device of the present invention may create a desired combination of time zones by repeating an operation of designating a part of the time zones displayed in the zone diagram. For example, in FIG. 7, a zone diagram created by designating the time zone on Monday early morning, daytime, and night may be called.

  Note that the time zone information displayed on the display screens of FIGS. 5 and 7 (for example, the character information shown in the display fields 55, 55,... In FIG. 7) is displayed as part of the time zone definition data. Whether the time zone information is displayed or not is switched by operating the time zone display button 57 shown in FIG. The time zone information is displayed in the area 56a on the setting screen shown in FIG.

  The time axis definition content created in accordance with the user's designation via the display time designation receiving means 14 is stored in the information display storage unit 12A (FIG. 1) as time zone definition data, and is displayed by the display means 12 in a timely manner according to the user's instructions. Made available.

  In this way, the user can freely create time zone definition data, which is reflected in the display mode of the zone diagram. Further, the time zone definition data stored in the information display storage unit 12A can be used at any time.

Specific examples of the definition contents of the time zone definition data are shown below.
(1) A specific time zone for each day of the week, for example, midnight, early morning, morning, noon, afternoon, night at each day of the week is defined as a time zone, and the start time and end time are defined.
(2) A specific time zone for each holiday or weekday, for example, midnight, early morning, morning, noon, afternoon, night at holidays, weekdays, weekdays before holidays, and the start time and end time of each are defined. To do.
(3) Any combination of start time and end time can be created. For example, the occurrence time of an event that can be identified from the state of the device is defined as the start time, and any time thereafter is defined as the end time.
(4) A new time zone is defined by combining saved time zone definition data, or by selecting and combining time zones from the saved time zone definition data.
(5) As described above, the unit of the time zone on the time axis (week, day, hour, minute, etc.) is set.

  FIG. 8 is a diagram illustrating a zone diagram when a plurality of indices are selected. In the example of FIG. 8A, the power consumption amount and the alarm level (level) are selected as index values, and both are displayed superimposed on the same rectangular area 51, 51,. The relationship between the alarm level and its display form is shown in area 58. As shown in the area 58, the alarm level is expressed as a pattern attached to each rectangular area 51, and the display color of each rectangular area 51 indicating the power consumption is visible. For this reason, the power consumption amount and the alarm level in the same device, the same time zone, and the level of the alarm can be superimposed on each other in the same rectangular area 51.

  In this way, the superposition display of the two index values can be instructed by operating the check box 59a and the list box 59b shown in FIG. In the list box 59b, index value candidates to be additionally displayed are displayed, and the user can select any index value from the candidates.

  As such a superimposed display method, in addition to a method of superimposing the display color and the pattern, a method of superimposing the display color and the luminance determined by another index value can be adopted. Moreover, it is also possible to perform a superimposed display using luminance and a pattern. In addition, superimposed display using icons with respect to display color, pattern, and luminance can be used (FIG. 8B).

  Next, the correspondence between the vertical axis and the device in the zone diagram follows the user's designation via the device designation accepting means 16.

  For example, as a movement operation in units of rows (for each device) in the zone diagram, the user selects one or more rows (devices) to be moved on the zone diagram shown in FIG. 3, drags them, and drops them on the destination row. can do. Such a movement operation is received by the function of the device designation receiving means 16. In this case, the calculation unit 12a of the display unit 12 replaces the order of the rows by inserting a row to be moved to the upper or lower row of the dropped destination row, and the display unit 12 updates the zone diagram updated by the replacement of the rows. Is displayed again.

  Further, the user can perform a sorting operation based on the index values at the same time or time zone. In this case, the user selects a row (device) to be sorted on the zone diagram of FIG. 3, and further selects a time or a time zone to be sorted. Furthermore, the descending order and the ascending order are selected as the sort order. Such a selection operation is received by the function of the device designation receiving means 16. The calculation unit 12a of the display unit 12 calculates the order of the rows (devices) to be sorted based on the index value at the time or time zone to be sorted. When a time zone is specified as the sort target, secondary index values such as the average value, maximum value, minimum value, median value, standard deviation, etc. can be selected from each index value of the time included in the time zone as necessary. You may calculate and sort according to this index value. The display means 12 redisplays the new zone diagram updated by the row sorting.

  Furthermore, according to a user instruction, the index values shown in the zone diagram can be rearranged in units of rows using a cluster analysis method such as a K-average method.

  In this case, the user selects a row (device) to be rearranged on the zone diagram of FIG. 3, and further selects a time or a time zone to be rearranged. Such a selection operation is received by the function of the device designation receiving means 16. The calculation unit 12a of the display unit 12 obtains the distance between the rows from the respective index values at the time or time zone to be rearranged, and allocates a cluster to each row. Next, the arithmetic unit 12a rearranges only the rows to be rearranged among the entire rows so that the row order is the cluster order, and the rows of the same cluster are adjacent to each other, and the display unit 12 is updated by the rearrangement. Redisplay the new zone diagram.

  FIG. 9 shows an example of a zone diagram after rearrangement in units of rows using the cluster analysis method. As shown in FIG. 9, by rearranging the order of the rows in the order of the clusters, it is possible to arrange the rows having a strong correlation and similar to each other at close positions, and to easily arrange a group of devices and periods having similar behaviors. It becomes possible to grasp.

  FIG. 10 is a diagram illustrating an example of a screen that accepts a level content change operation. The reception of the level content changing operation is executed as a function of the display form designation receiving means 15. The calculation unit 12 a executes a calculation according to the received content, and the calculation result is reflected in the display by the display means 12.

  The level content changing operation includes level addition / deletion, level threshold value, and rectangular color setting. In the screen example of FIG. 10, an area 61 for receiving level editing, an area 62 indicating the current level setting state, a button 63 for additionally setting a level being edited, and a level being edited are deleted. Button 64 is provided.

  FIG. 11 shows an example in which a new level is additionally set by an operation on the screen shown in FIG. In the example of FIG. 11, five levels are set before the level setting is changed, but after the level setting, one level is added to make six levels. As described above, by allowing the user to freely change the level setting, it is possible to obtain a level setting state in which necessary information is appropriately expressed on the zone diagram. For example, in the example of FIG. 11, it is possible to express an area of “90” or more and “100” or less from the area of less than “90” on the zone diagram. The user can change the level setting state while visually recognizing the display color change of each rectangle according to the contents of the new level setting state.

  As described above, the power information monitoring apparatus 1 displays a zone diagram and extracts similar rows, whereby a group of devices having similar transitions in index values such as power consumption can be found. However, when making improvements in energy saving, it is necessary to further narrow down the devices to be improved by comparing the devices using the correlations and index values of various indexes in the device group. When performing such work, the scatter diagram operation accepting means 17 (FIG. 1), which is an example of an operation accepting means such as a graph, can be provided in the power collecting apparatus. Thereby, the apparatus etc. which should be improved can be narrowed down easily by operation which combined the zone diagram and the distribution map (for example, scatter diagram).

  FIG. 12 is a diagram showing a screen example in which a scatter diagram which is an example of a distribution diagram is displayed in addition to the zone diagram.

  As shown in FIG. 12, a zone diagram 50 and a scatter diagram 70, which is an example of a distribution map, are displayed side by side on the screen. The device and time (or time zone) to be displayed in the scatter diagram 70 can be designated by the user's operation on the zone diagram 50. In FIG. 12, the corresponding device and time are selected by the operation of selecting the area 50a. Is specified.

  Further, the index value assigned to the X axis of the scatter diagram 70 can be designated by the user by the list box 71, and the index value assigned to the Y axis of the scatter diagram 70 can be designated by the user by the list box 72, respectively. In the example of FIG. 12, the traffic amount is designated on the X axis, and the packet discard rate is designated on the Y axis. Note that the traffic amount indicates the communication amount of the device, and the packet discard rate indicates the ratio of discarding the received communication packet, which can be used as an index value correlated with the power consumption amount.

  When the area 50a is selected, the index values are displayed in the list box 71 and the list box 72, and the button 73 is operated, the processing unit 12a disperses the device corresponding to the area 50a and the time (or time zone) narrowed down. FIG. 70 is created. Further, the created scatter diagram 70 is displayed on the display device 12 or updated.

  Further, when the XY coordinate range in the scatter diagram 70 is selected and the button 74 is operated, the zone diagram 50 narrowed down to the device and time (or time zone) corresponding to the XY coordinate range in the computing unit 12a. Created. Further, the created zone diagram 50 is displayed on the display device 12 or updated.

  FIG. 13 is a diagram illustrating the procedure of the narrowing-down operation using such a scatter diagram 70 and zone diagram 50.

  In the example of FIG. 13, in the procedure (1), the user calls a zone diagram using the power consumption amount per day as an index value, and designates the area 81 of the zone diagram to thereby consume power per day. Select a device with a large amount and call up a distribution chart (apparatus behavior distribution chart) that plots the equipment. In this device behavior distribution, the traffic volume (unit: bit per second) is taken on the X-axis and the traffic / power consumption (unit: bit per watt-hour) is taken on the Y-axis, and plotted for each selected device. Has been.

  Next, in step (2), by specifying the area 82 of the displayed distribution map (device behavior distribution map), a device with low traffic / power consumption is regarded as a device with low efficiency, and is selected. To check the behavior of the device, call the zone diagram. As shown in FIG. 13, in this zone diagram, the traffic / power consumption amount of each device is used as an index value, and the index value is displayed in units of time.

  Next, in step (3), by designating a newly displayed zone diagram area 83, a time with less traffic / power consumption is selected for the inefficient device, and the time unit behavior distribution of the device is selected. Call the figure. In the time unit behavior distribution chart of this device, the packet discard rate (= number of discarded packets / total number of input / output packets, unit:%) is plotted on the X axis, and traffic / power consumption is plotted on the Y axis. The behavior of each time for each device selected by the region 82 of the diagram (device behavior distribution diagram) is plotted.

  Next, in the procedure (4), the user can compare the behavior of each device at each time on the time unit behavior distribution diagram of the device. For example, it is possible to specify a point to be improved by giving priority to the time of a device exhibiting a behavior that tends to have a small traffic / power consumption amount and a high packet discard rate. For example, region 84 in FIG. 13 corresponds to such behavior.

  It should be noted that the operation accepting means such as a graph can compare not only the display by the scatter diagram but also the behavior of each device at each time, and the display device 12 can display the zone diagram by narrowing down the devices to be displayed. For example, a line graph display, a pie chart display, or other distribution diagrams may be used.

  As described above, according to the device data display device of the present invention, the time series data of each device is represented by a zone diagram in which display areas such as display colors, brightness, patterns, and icons are arranged side by side. It is possible to browse changes in time-series behavior at a time for indicators representing the operation status of devices collected via a network from a large number of devices at regular intervals, and perform analysis simply and intuitively. Will be able to. Furthermore, it is possible to verify the similarity of the behaviors of devices and to discover the occurrence of a specific event.

  For example, the grouping operation of devices having similar time-series behavior in the currently displayed index value can be performed based on the similarity in color tone. Furthermore, as a result of manually or automatically collecting rows with strong correlation, it is possible to confirm the similarity of the behavior of the devices based on the similarity of the color tone (FIG. 9). Further, by performing the overlay display (FIG. 8), in the group of devices that are visually recognized as having similar behavior in the currently displayed index value, while viewing the similarity, The state of the behavior of the device (for example, an abnormality occurrence pattern) can be visually recognized.

  Further, the relationship between the behavior of the device based on the currently displayed index value and the user's social activity can be grasped based on the time zone defined by the user. In addition, if attention is paid to behavior changes in a specific time zone in the currently displayed index value, that time zone is selected, and only the behaviors in that time zone are displayed side by side. The tendency of deterioration / improvement can be grasped (FIGS. 5 to 7).

  In addition, the threshold value for determining the level of the currently displayed index value is dynamically changed, and the dynamic change of the display form (color tone, brightness, icon or pattern) is visually recognized, for example, a stronger behavioral similarity The devices can be regrouped so as to have the characteristics (FIGS. 10 to 11).

  In addition, since the type of index value to be displayed can be changed, it is possible to change the display to the display with the newly selected index value while maintaining the arrangement order in the row direction and the column direction currently being displayed. In the group of devices that are visually recognized as having similar behavior in the index values that have been displayed up to, when viewed from another index value, for example, it is possible to find devices and periods that are not similar.

  Furthermore, various analyzes can be efficiently performed by combining the zone diagram and the distribution diagram.

  The scope of application of the present invention is not limited to the above embodiment. The present invention can be widely applied to a device data display device that displays values of time series data collected from a plurality of devices.
