  As described above, detection information from the various sensors of the sensor group 41, the camera 42, and the recording device 43 is transmitted to the control unit 50. The detection information received by the control unit 50 is recorded in a recording device such as a hard disk of the control unit 50 while being associated with the time when the information is acquired. As described above, the detection information is recorded in the recording device in association with the acquisition time, so that the control unit 50 can extract only the portion corresponding to the specific time in the detection information from the recording content of the recording device. . Detection information extracted from the recording device for a portion corresponding to a specific time is used for display on a display 31 and a sound output from the speaker 32 in a monitoring screen IM, a moving image reproduction area N, and an audio reproduction area V, which will be described later.

  The control unit 50 displays the monitoring screen IM shown in FIG. The monitoring screen IM includes a graph display area d1 and an indicated time point display area d2 which are areas for displaying detection information corresponding to digital values, and a graph which is an area for displaying detection information corresponding to analog values. A display area a1 and an indicated time point display area a2 are included. Detection information corresponding to digital values (hereinafter referred to as digital detection values) refers to detection items whose operation status is expressed in binary, such as values indicating the on / off status of various devices and equipment, and values indicating the opening and closing of valves. It corresponds to such detection information. Hereinafter, a state in which various devices are turned on and a valve open state are collectively referred to as an on state. In addition, a state in which various devices are turned off and a valve closed state are collectively referred to as an off state. Detection information corresponding to an analog value (hereinafter referred to as an analog detection value) refers to a detection item in which the operating state is indicated by a continuous amount, such as a power value, a current value, a voltage value, and a height value indicating a water level. It corresponds to detection information.

  As shown in FIG. 3A, the graph display area d1 is a window image area in which a graph showing a time change of the digital detection value is displayed for a plurality of detection items. The detection items displayed in the graph display area d1 are those freely selected in advance by the user from detection item groups by detection means such as the sensor group 41. A title related to the display content is included at the top of the graph display area d1. In the left part of the graph display area d1, an item row K1 in which the names of six detection items such as “generator“ stop ”” and “oil return pump” are arranged in the vertical direction is displayed. A graph is displayed on the right.The horizontal axis of the graph represents time.The scale of the horizontal axis is provided at regular time intervals and shows the date and time when the detection information was acquired. The graphs g1 to g6 are included.The staircase graphs g1 to g6 are arranged in the vertical direction, and the vertical positions thereof correspond to the positions of the names of the detection items displayed on the left side. In each of the graphs g1 to g6, a high portion indicates an on state, and a low portion indicates an off state, for example, “HIGH” and “LOW” in FIG. The high and low parts of g1 It is. The high portion of graph g1 indicates that the generator is in a “stop” state during that time range, and the low portion of graph g1 indicates that the generator is not in a “stop” state during that time range. Show.

  The graph display area d1 includes a vertical line cursor C1 (first instruction image) that indicates one point in the graph (hereinafter referred to as a cursor instruction point). The position of the vertical line cursor C1 with respect to the horizontal axis of the graph corresponds to the cursor indication time. The background color of the item column K1 on the left side of the graph display area d1 indicates the detection information of each detection item at the time of the cursor instruction. For example, an item with a colored background is an item for which the detection information at the time when the cursor is designated is on. An item that is not colored in the background is an item for which detection information at the time of the cursor instruction of the item is in an off state. In FIG. 3 (a), the hatched area corresponds to the colored area, and the hatched area corresponds to the uncolored area. 3A, only the item “generator“ stop ”” is in the on state, and the other items are in the off state, and are therefore colored in the item row K1. Only the background of “generator“ stop ”” and other items are not colored, and the user can freely select the coloring type of the items in advance.

  The designated time point display area d2 is a window image area in which digital detection values relating to a plurality of detection items are displayed, as shown in FIG. The detection items related to the display contents of the instruction time point display area d2 are those freely selected in advance by the user from the detection item group by the detection means such as the sensor group 41. The detection items displayed in the designated time point display area d2 may all match the detection items displayed in the graph display area d1, or may partially match, or may all be different. .

  In the designated time point display area d2, unlike the graph display area d1 in which the time change of the digital detection value is displayed, the digital detection value at one point in time of the cursor instruction time is displayed. A title related to the display content is included at the top of the graph display area d1. A plurality of horizontally long cells are arranged vertically and horizontally below the title. Each horizontal cell has the name of the detection item such as “generator“ stop ”” “field conductor” etc. The background color of each horizontal cell indicates the detection information of each detection item at the time of cursor indication. For example, a horizontally long cell with a colored background indicates that the detection information at the time of the cursor indication related to the detection item of the horizontally long cell is in an on state. 3B shows that the detection information at the time of the cursor instruction related to the detection item is in an OFF state, where the hatched area is colored in the hatched area and the hatched area is colored. 3 (b), only the three items “stop”, “high-efficiency operation” and “guide vane lock” are in the on state, and the other items are off. Therefore, the background of the horizontally long cell in the designated time point display area d2 is colored only in the background of the horizontally long cell in which the names of the above three items are described, and the background of the other horizontally long cells is colored. 3B, the detection items “stop”, “preparation”, “start”, etc. in the indicated time point display area d2 are the detection items “generator” stop in the graph display area d1 in FIG. “” “Generator“ Preparation ”” “Generator“ Startup ””, etc. Therefore, FIG. 3 (a) and FIG. 3 (b) are detections related to these common detection items. The display contents of information (whether they are in an on state or an off state) match, and the color type of the horizontally long cell can be freely selected in advance by the user.

  As shown in FIG. 4A, the graph display area a1 is a window image area in which a graph showing a time change of the digital detection value is displayed for a plurality of detection items. The detection items displayed in the graph display area a1 are freely selected in advance by the user from the detection item group by the detection means such as the sensor group 41. A title related to the display content is included at the top of the graph display area a1. In the left part of the graph display area a1, an item row K2 in which names of five detection items such as “normal pressure oil tank hydraulic pressure” and “brake tank” are arranged in the vertical direction is displayed. Above the name of each detection item displayed in the item row K2, an analog detection value that is detection information of each detection item is displayed. Each analog detection value displayed in the item row K2 is a value at the time of the cursor instruction. Markers s1 to s5 are displayed on the right side of the display of the detection information. The markers s1 to s5 are expressed in colors preset by the user for each detection item. A graph is displayed on the right side of the item column K2. The horizontal axis of the graph represents time. The scale on the horizontal axis is provided at regular time intervals and indicates the date and time when the detection information is acquired. The graph includes line graphs g11 to g15. The line graphs g11 to g15 correspond to the five detection items in the item row K2. The line graphs g11 to g15 are expressed in colors set by the user for the corresponding detection items (that is, the colors indicated by the markers s1 to s5). In FIG. 4A, the line graphs g11 to g15 are represented by different line types, thereby expressing the difference between the colors of these line graphs.

  The graph display area a1 includes a vertical line cursor C2 that indicates the same time point as the cursor instruction time pointed by the vertical line cursor C1. The vertical line cursor C2 is displayed at a position corresponding to the cursor instruction point on the horizontal axis of the graph.

  The designated time point display area a2 is a window image area in which analog detection values are displayed for a plurality of detection items, as shown in FIG. 4B. The detection items displayed in the designated time point display area a2 are freely selected in advance by the user from the detection item group by the detection means such as the sensor group 41. The detection items related to the display contents of the indication time point display area a2 may all match the detection items related to the display contents of the graph display area a1, may only partially match, or may all be different. Also good.

  Unlike the graph display area a1 in which the time change of the analog detection value is displayed, the instruction time display area a2 displays the analog detection value at a temporary point at the cursor instruction time. A title related to the display content is included at the top of the instruction time point display area a2. A plurality of vertically long cells are arranged vertically and horizontally below the title. In each of the vertically long cells, a bar graph indicating the name of the detection item, the analog detection value at the cursor instruction time point, and the analog detection value at the cursor instruction time point is displayed in order from the top. For example, a vertical cell surrounded by a one-dot chain line frame L in FIG. 4B, which is one of the vertical cells, has a detection item name “power station 1 water level” and an analog detection value at the time of the cursor instruction. It includes a certain 1.38 (meter) and a bar graph indicating 1.38 (meter) which is an analog detection value at the time of cursor indication. The detection item “guide vane opening” in the indicated time point display area a2 in FIG. 4B is a detection item common to the detection item “guide vane opening” in the graph display area a1 in FIG. . Therefore, FIG. 4 (a) and FIG. 4 (b) match the display contents (opening 0.0%) of the detection information related to these common detection items.

  Based on the input from the user through the pointing device 22, the control unit 50 changes the cursor instruction time point by the vertical line cursors C1 and C2 displayed in the graph display areas d1 and a1. For example, when a mouse is used as the pointing device 22, the user clicks the mouse button with the mouse cursor M placed in any one of the graph display areas d 1 as shown in FIG. . As a result, an input (first input) indicating a position in the graph display area d1 is accepted through the mouse (pointing device 22). Based on the input using the mouse, the control unit 50 moves the vertical cursor C1 to a position indicated by the mouse cursor (a position indicated by a two-dot chain line in FIG. 3A). Thereby, the cursor indication time pointed by the vertical line cursor C1 changes to a time point corresponding to the position indicated by the input using the mouse. Then, the control unit 50 also moves the vertical line cursor C2 to a position that indicates the cursor instruction time point by the vertical line cursor C1 after the instruction content is changed as described above. In this way, the control unit 50 changes the display contents of the vertical line cursors C1 and C2 based on the user input indicating the position in the graph display area d1. Similarly, in the present embodiment, in the graph display area a1, the user can make an input (first input) to specify a position using the pointing device 22. When such an input is performed, the control unit 50 changes the display contents of the vertical line cursors C1 and C2 based on the position indicated by the input, as described above.

  When the display contents (display position) of the vertical line cursors C1 and C2 are changed as described above, the control unit 50 further displays the display contents in both the designated time point display areas d2 and a2 as the vertical line cursors C1 and C2. At the same time, the display contents are changed to the contents corresponding to the cursor indication time after the display contents are changed. Specifically, the control unit 50 updates all the background colors of the horizontally long cells in the designated time display area d2 so as to indicate the detection information at the cursor designated time after the change. For example, as shown in FIG. 3 (a), at the time of the cursor instruction by the vertical line cursor C1 (solid line) before the change, “generator“ stop ”” is in an on state, and “generator“ parallel ”” and On the other hand, “generator“ load ”” is in the off state, whereas “generator“ stop ”” is in the off state at the time of the cursor indication by the vertical line cursor C1 (two-dot chain line) after the change. “Generator“ Parallel ”” and “Generator“ Load ”” are in the ON state, so that the control unit 50 displays the “generator“ stop ”” horizontally long in the designated time point display area d2 shown in FIG. While the background color of the cell is changed to none, the background color of the horizontally long cells of “generator“ parallel ”” and “generator“ load ”” is changed to “present.” Other detection items are also updated in the same manner. When the display content of the indication time display area d2 is updated in this way Sometimes, the control unit 50 also updates all the display contents of each vertically long cell in the designated time point display area a2 to indicate the detection information at the cursor designated time point after the change, that is, the analog detection value and the bar graph in each vertically long cell are displayed. The contents are updated to the contents corresponding to the cursor instruction time after the change.

  As shown in FIG. 2, the monitoring screen IM includes a display range instruction area t in addition to the graph display areas d1 and a1 and the instruction time point display areas d2 and a2. The display range instruction area t is an image area for instructing the display range on the horizontal axis of the graph display areas d1 and a1. The display range instruction area t includes a time scale t1, a range instruction bar tb (second instruction image), and an arrow icon t2. The time scale t1 is provided with a scale at predetermined time intervals. The range instruction bar tb occupies a predetermined range on the time scale t1. In FIG. 2, the range occupied by the range indication bar tb is indicated by hatching. The range that the range instruction bar tb occupies on the time scale t1 corresponds to the display range on the horizontal axis of each of the graph display areas d1 and a1. In the example shown in FIGS. 2, 3 (a) and 4 (a), the range is from 7:40 to 8:40 on March 13, 2016.

  The control unit 50 changes the range indicated by the range indication bar tb based on the following input (second input) by the user through the pointing device 22. When the user moves the designated position to the left or right in a state where the user has designated the start point or end point of the range indication bar tb through the pointing device 22, the control unit 50 moves the start point or end point of the range indication bar tb to a position according to the user's operation. To change. FIG. 5A shows a case where the end point of the range instruction bar tb is shifted to the right as an example. When the end point of the range indication bar tb is indicated using the pointing device 22 from the state of the upper diagram of FIG. 5A and the indicated position is shifted to the right, the range indication is obtained as shown in the lower diagram of FIG. The end point of the bar tb moves to the right.

  When the user indicates the arrow icon t2 of FIG. 1 through the pointing device 22, the control unit 50 changes the positions of the start point and the end point of the range instruction bar tb without changing the left and right lengths of the range instruction bar tb. To do. That is, the control unit 50 slides the range instruction bar tb to the left and right.

  Then, the control unit 50 updates the display content of the range instruction bar tb so as to correspond to the changed range, and changes the display range of the horizontal axis in the graph display areas d1 and a1 to the range instruction bar tb after the range change. Update to the range indicated by. Furthermore, the control unit 50 updates the display contents of the graphs g1 to g15 in the graph display areas d1 and a1 to the contents corresponding to the display range of the changed graph horizontal axis. FIG. 5B shows, as an example, the updated contents of the graph display area d1 when the display contents of the range instruction bar tb are changed as shown in FIG. The upper diagram in FIG. 5B shows the content before update, and the lower diagram in FIG. 5B shows the content after update. The alternate long and short dash line in the graph in the lower diagram of FIG. 5B indicates the end of the display range of the graph before the update. After the update, the display range of the pre-update graph is widened in the direction of the future by the amount by which the end point of the range instruction bar tb is shifted to the right.

  When the range of the range indication bar tb is changed, the control unit 50 updates the display range of the time scale t1 according to the changed content, and the range occupied by the range indication bar tb according to the updated time scale t1 (that is, the range indicated by the range indication bar tb). , The positions of both ends of the range instruction bar tb) are updated. For example, as shown in the upper diagram of FIG. 6A, it is assumed that the range indication bar tb after the range change occupies a relatively large range on the time scale t1. Specifically, it is assumed that the range occupied by the range instruction bar tb with respect to the display range of the time scale t1 is a predetermined ratio or more. In such a case, the control unit 50 widens the display range of the time scale t1. And the control part 50 updates the range which the range instruction | indication bar tb occupies according to the display range of the time scale t1 after expanding. As a result, as shown in the lower diagram of FIG. 6A, the display range of the range instruction bar tb becomes relatively narrow with respect to the time scale t1. A dashed line in the lower diagram of FIG. 6A indicates the display range of the time scale t1 before the update. On the contrary, when the range indication bar tb after the range change occupies a relatively small range on the time scale t1, the control unit 50 narrows and narrows the display range of the time scale t1 itself. The range occupied by the range indication bar tb is updated according to the display range of the later time scale t1 itself. As a result, the display range of the range instruction bar tb is relatively wide with respect to the time scale t1.

  Further, as shown in the upper diagram of FIG. 6B, it is assumed that the range instruction bar tb after the range change is relatively close to either the left or right on the time scale t1. Specifically, it is assumed that the center in the left-right direction of the range instruction bar tb is shifted by a predetermined amount or more with respect to the center of the time scale t1. In such a case, the control unit 50 shifts the display range of the time scale t1 to either the direction going back in the past or the direction going to the future. And the control part 50 updates the range which the range instruction | indication bar tb occupies according to the display range of the time scale t1 after narrowing. As a result, as shown in the lower diagram of FIG. 6B, the display range of the range instruction bar tb is changed so as to be closer to the center of the time scale t1. The alternate long and short dash line in the lower diagram of FIG. 6B indicates the display range of the time scale t1 before the update.

  In addition to displaying the above monitoring screen IM on the display 31, the control unit 50 causes the display 31 to display the moving image reproduction area N shown in FIG. 7 and the audio reproduction area V shown in FIG. The moving image reproduction area N and the audio reproduction area V can be displayed on the display 31 simultaneously with the monitoring screen IM. The moving image reproduction area N is a window image area for reproducing a moving image acquired by the camera 42. At the top of the moving image playback area N, a title indicating the equipment that is the subject of shooting is displayed. In the area under the title, a portion of a predetermined period starting from the cursor instruction point in the recorded moving image is reproduced. The audio playback area V is a window image area that displays the waveform of the audio recorded by the recorder 43. At the top of the audio reproduction area V, a title indicating that audio reproduction is being performed is displayed. In the area under the title, a sound waveform of a predetermined period starting from the cursor indication time is displayed. FIG. 8 includes, as an example, a waveform display area for each of “portable microphone 1” and “portable microphone 2” included in the recorder 43. Furthermore, the control unit 50 causes the speaker 32 to output sound corresponding to the displayed waveform simultaneously with the display of the sound waveform.

  When the display position of the vertical line cursor C1 or C2 is changed in the graph display area d1 or a1 by the input from the user through the pointing device 22, the control unit 50 displays the moving image reproduction area N and the audio reproduction area V. In both cases, the display contents are updated to the display contents corresponding to the cursor indication time point by the vertical line cursors C1 and C2 after the position change. Specifically, a portion of a recorded period of a predetermined period from the cursor instruction point after change is reproduced in the moving image reproduction area N. In addition, a sound waveform for a predetermined period from the cursor instruction time after the change is displayed in the sound reproduction area V. Furthermore, the control unit 50 causes the speaker 32 to output sound corresponding to the sound waveform after the display change. The update of the display contents in the moving image reproduction area N and the audio reproduction area V and the output of the updated sound from the speaker 32 are executed simultaneously with the update of the display contents in the designated time point display areas d2 and a2.

  According to the state monitoring system 1 of the present embodiment described above, the user can generally grasp the transition of the operating state of the target system 90 by looking at the graph display area d1 or a1.

According to the present embodiment, when a time point at which an abnormality is considered to be indicated is indicated by the vertical cursor C1 or C2, details of detection information at a required time point are displayed in the indicated time point display areas d2 and a2 having different display modes. It can be displayed all at once. Therefore, it is possible to acquire the detailed information necessary for specifying the cause of the abnormality extensively and quickly. In the present embodiment, two display point display areas d2 and a2 are simultaneously displayed on the display 31 as areas for displaying the detection information of the temporary points. However, another window image area that allows the user to freely select and display a detection item, such as the designated time point display areas d2 and a2, may be displayed on the display 31 together with the designated time point display areas d2 and a2. Such an additional window image area preferably has a display mode different from that of each of the designated time point display areas d2 and a2, but may have a display mode similar to these areas. When the instruction content of the vertical line cursor C1 or C2 is changed, the display content is also changed in these additional window image areas simultaneously with the change of the display contents in the instruction time point display areas d2 and a2.

  In the present embodiment, the range instruction bar tb indicates the temporal range for displaying the graph display areas d1 and a1. When the position of the range indication bar tb is indicated by a user input using the pointing device 22, the indication content of the range indication bar tb is changed and a graph is displayed so that the content corresponds to the changed time range. Regions d1 and a1 are updated. Therefore, the graph display areas d1 and a1 can be changed by a simple and quick operation. Further, in the present embodiment, it is possible to instruct and change the time range for displaying the graph by a visual operation of operating the range instruction bar tb extending from the start point position to the end point position on the time scale t1. Therefore, the user can easily perform a change operation of the time range sensuously. When the instruction content of the range instruction bar tb is changed, the display range of the time scale t1 is updated according to the range and position occupied on the time scale t1 of the changed range instruction bar tb, and the range instruction bar tb Is updated to a range corresponding to the updated time scale t1. That is, the display range and position of the range instruction bar tb are adjusted to an appropriate range with respect to the time scale t1. Therefore, the range instruction bar tb is displayed in an easy-to-see manner.

  In the present embodiment, the graph display area d1 and the designated time point display area d2 display digital detection values, and the graph display area a1 and the designated time point display area a2 display analog detection values. That is, the digital detection value and the analog detection value are displayed separately. For this reason, the user can easily grasp at a glance the detection information displayed for a plurality of detection items in each region.

  In the present embodiment, when the instruction content of the vertical line cursor C1 or C2 is changed, not only the instruction time point display areas d2 and a2, but also the moving image reproduction area N and the audio reproduction area V are simultaneously updated, and the speaker. The audio output from 32 is also updated at the same time. Therefore, when it is necessary to know the details of the detection information at a certain point in time as a result of generally grasping the transition of the operating state based on the graph display area d1 or a1, if the point in time is indicated by the vertical line cursor C1 or C2, The output content of the video and the output content of the audio are also updated at the same time. As a result, it is possible to grasp the details of the operating state at the point of time to know more widely and quickly.
