  By the way, the monitored property and the monitoring area have various states such as “failure state”, “maintenance state”, “live display state”, etc. of devices such as cameras in addition to “abnormal state” such as intrusion and fire. However, in the above conventional method, symbols in an abnormal state are merely identified and displayed in red, and no consideration is given to displaying symbols having various states so that the states can be identified at a glance. Therefore, it is not easy for a user to search for and select a symbol of a monitored property in a state (a specific state) that the user desires to confirm.

  In addition, in the conventional method described above, there is no consideration when there are a large number of monitoring areas in one monitored property (monitoring section) (for example, a skyscraper or a large-scale shopping center). It is not easy to select a camera by designating a monitoring area desired by a user from an area (for example, floors from the first floor to the 60th floor). It is desirable that a user can easily select a desired monitoring area after selecting a monitoring section. In particular, if any monitoring area in the selected monitored property is in a specific state (for example, a state in which an abnormality has occurred), so that the user can easily confirm the location in such a state, It is desirable to be able to quickly select a monitoring area in such a state. Furthermore, in that case, the user designates the state so that the user does not have to re-specify the state each time the display of the monitoring property map (area map) and the monitoring area floor plan (floor map) is switched. It is desirable to be able to take over the state between the map and the plan view (between maps).

  The present invention has been made in view of the above-described problems. When a monitoring property in a state designated in advance by a user is selected, the monitoring area in that state can be easily confirmed.

Superimposed near the image. The state to be included in the second aggregation condition can be designated / cancelled by performing an operation input for selecting a symbol on the screen on which the thumbnail list is displayed. That is, on the screen on which the thumbnail list is displayed, the second aggregation condition is displayed so as to be changeable.

  When a thumbnail image of a certain monitoring area (for example, the second floor) is selected by the operation unit 9 in the thumbnail list window, an enlarged plan view (floor map) of the monitoring area is displayed on the floor map window (right window). ) Is displayed. In this case, also on the floor map, the monitoring means (monitoring camera 2) in which the small symbol “abnormal occurrence” (small symbol in a circle) included in the second aggregation condition matches the second aggregation condition The symbol (camera symbol) of the monitoring means (monitoring camera 2) is highlighted. The second aggregation condition can be designated / cancelled by the user performing an operation input for selecting a symbol even on the screen on which the floor map is displayed. That is, the second aggregation condition can be changed on the screen on which the floor map is displayed.

  As shown in FIG. 4, when the second aggregation condition is changed on the screen where the thumbnail list or the floor map is displayed, the first aggregation condition is adjusted to the second aggregation condition after the change. Update processing is performed. For example, as shown in FIG. 4, when the designation of “intimidating” is canceled on the screen on which the thumbnail list or the floor map is displayed, and the second aggregation condition is changed to “being abnormal” only The process of updating the first aggregation condition to “being abnormal” is performed.

  Therefore, when the display is switched from the monitoring area screen (thumbnail list or floor map screen) to the monitored property screen (area map screen), an error message appears in the first aggregation condition window (upper left window). Only the “occurrence” symbol (circle symbol) is highlighted, and only the “abnormality occurrence” small symbol (circle symbol) is also highlighted on the area map. In this case, a small symbol (abnormal symbol) indicating the first aggregation condition is superimposed near the monitored property (monitored property A) that matches the updated first aggregation condition. Is displayed. Note that on the area map, a small symbol may be superimposed and displayed indicating a state in which the designation is canceled from the first aggregation condition. In the example of FIG. 4, small symbols of “live display” and “intimidating” (small symbols of triangles and squares) are property symbols of the monitored properties (monitored properties B and C) in that state. They are superimposed on each other. These small symbols (small symbols indicating a state not included in the aggregation condition) are not highlighted (not highlighted).

  As shown in FIG. 5, when the second aggregation condition is not changed on the screen on which the thumbnail list and the floor map are displayed, the process for updating the first aggregation condition is not performed. The aggregation conditions of “Abnormal”, “Live display”, and “Intimidating” remain.

  Therefore, when the display is switched from the monitoring area screen (thumbnail list or floor map screen) to the monitored property screen (area map screen), the screen returns to the original area map screen. In other words, the “Abnormal”, “Live”, and “Intimidating” symbols ((circle, triangle, and square symbols) are highlighted in the first aggregation condition window (upper left window). On the area map, there are small symbols (small, round, triangle, and square) that are “abnormal”, “live” and “intimidating” indicating the first aggregation condition. In addition to being superposed and displayed near the property symbol of the monitored property (monitored property A, B) that matches one aggregation condition, the symbol (property symbol) of the monitored property is highlighted.

  As shown in FIGS. 3 to 5, symbols indicating these monitoring means (monitoring camera 2) are superimposed on the floor map at the installation position of the monitoring means (for example, monitoring camera 2), and the display control unit 14. When these symbols (symbols of the monitoring means displayed on the floor map) are selected and operated by the operation unit 9, they are accepted as display requests for image data and status information display requests to the monitoring camera 2 and the image recording device 3. The image data and status information are displayed and output on the display unit 8. Further, when the image data being displayed is selected and operated by the operation unit 9, the display control unit 14 accepts the image data display stop request and ends the display of the image data.

  When the image data being displayed is specified from the operation unit 9 and an image recording request is input from the operation unit 9, the recording processing unit 15 corresponds to the image data received from the monitoring camera 2 according to the identification information of the monitoring camera 2 and the shooting time. And recorded in the image recording unit 11.

  About the monitoring apparatus 4 comprised as mentioned above, the operation | movement is demonstrated with reference to drawings.

  First, the operation (main flow) of the monitoring device 4 of the present embodiment will be described with reference to FIG. As shown in FIG. 6, when the dedicated program of the monitoring device 4 is activated, an area map screen (monitoring section selection screen) is first displayed on the display unit 8 (S1). Next, based on whether or not the first aggregation condition is set, the property symbol is highlighted on the monitoring section selection screen (S2). That is, if there is a monitored property that matches the first aggregation condition, the property symbol of the monitored property is highlighted. At this time, a small symbol indicating the first aggregation condition is superimposed and displayed near the property symbol of the monitored property.

  Subsequently, it is determined whether or not a property symbol has been selected on this monitoring section selection screen (S3). When the property symbol is selected, the monitoring area plan display process (thumbnail list and floor map display process) is performed (S4). If the property symbol is not selected, it is determined whether or not the first aggregation condition changing operation has been performed (S5). When the operation for changing the first aggregation condition is performed, a process for changing the first aggregation condition is executed (S6). When the change operation of the first aggregation condition is not performed, it is determined whether or not the end operation has been performed (S7). Then, when the end operation is performed, the dedicated program of the monitoring device 4 is ended.

  Next, a subflow of the monitoring area plan display process (thumbnail list and floor map display process) will be described with reference to FIG. As shown in FIG. 7, when the display process of the monitoring area plan is executed, the state of the monitoring means (the monitoring camera 2 and the image recording device 3) included in the selected monitoring property and the first aggregation condition A process of setting a state obtained by a logical product (AND) with the specified state as a second aggregation condition is performed (S10).

  Subsequently, only the thumbnail images of the monitoring area that meet the second aggregation condition are displayed in a list (S11), and whether or not the thumbnail image of the monitoring area is selected from the list of thumbnail images of the monitoring area (thumbnail list). A determination is made (S12). When a thumbnail image of the monitoring area is selected, an enlarged plan view (floor map) of the selected monitoring area is displayed (S13). On the floor map, the small symbol of the second aggregation condition is superimposed and displayed near the symbol (camera symbol) of the monitoring means (monitoring camera 2) that matches the second aggregation condition, and the monitoring means ( The symbol (camera symbol) of the monitoring camera 2) is highlighted (S14). When a symbol (camera symbol) of the monitoring camera 2 is selected on the screen on which the floor map is displayed (S15), a photographed image of the selected monitoring camera 2 is displayed (S16).

  It is determined whether or not the second aggregation condition changing operation has been performed on the screen on which the floor map is displayed (S17). When an operation for changing the second aggregation condition is performed, a process for changing the second aggregation condition is performed (S18), and a list display of only thumbnail images in the monitoring area that matches the second aggregation condition ( Return to S11). When the second aggregation condition is cleared (when all are not specified) (S19), thumbnail images of all monitoring areas are displayed in a list (S20), and whether thumbnail images of the monitoring areas are selected or not. Return to the determination (S12). In the second aggregation condition changing operation in step S18 in this embodiment, the second aggregation condition is set so that it cannot be changed for a state that has not occurred in the selected monitoring section (property). To do.

  Thereafter, when a return button (not shown) is pressed (S21), it is determined whether or not the second aggregation condition has been changed (S22). When the second aggregation condition is changed, the first aggregation condition is updated to be the second aggregation condition after the change (S23), and the monitoring area plan view display process (with thumbnail list and The floor map display process) ends. On the other hand, if the second aggregation condition is not changed, the first aggregation condition is not updated, and the monitoring area plan view display processing (thumbnail list and floor map display processing) ends.

  According to the monitoring device 4 of the present embodiment as described above, the symbols in the state designated as the aggregation condition by the user on the monitored property map (area map) are highlighted, and the occurrence location of such a state is displayed. It is possible to narrow down and select the monitoring area, and when the screen transitions between the monitoring property map (area map) and the monitoring area floor plan (floor map), the state that the user pays attention to at the present time is taken over As a result, unnecessary operations by the user can be reduced, and the screen can be shifted efficiently.

  That is, in the monitoring device 4 according to the present embodiment, the user can check the current state, that is, the state that should be monitored at the present time (for example, during the occurrence of an abnormality, during live display, during threatening, during voice acquisition, disconnection) When the first aggregation condition is specified when the display by the first display process (area map display) is performed as a state such as “medium”, the monitoring means (the monitoring camera 2 and the image recording) By identifying (for example, highlighting) the monitoring section (property) in which the device 3) is installed, the monitoring section can be easily specified. In addition, the user is in this state when the second aggregation condition is specified when the display by the second display step (display of the thumbnail list or the floor map) is performed as the state to be monitored. Information on the monitoring area where the monitoring means (the monitoring camera 2 and the image recording apparatus 3) is installed (for example, a monitoring area list and a plan view where the monitoring means (the monitoring camera 2 and the image recording apparatus 3) in that state are installed ) Is displayed, the monitoring area can be easily identified, and the status of the monitoring means (the monitoring camera 2 and the image recording device 3) can be easily confirmed.

  In addition, when the user changes the second aggregation condition while the display by the second display process (display of the thumbnail list or the floor map) is performed, the user then displays the display by the first display process (area map). Even if it is switched to (Display), it is not necessary to make the same change to the first aggregation condition, and information on the monitoring section (property) and monitoring area that should be monitored at the present time (for example, a plan view) can be easily The status of the monitoring means (the monitoring camera 2 and the image recording device 3) in such a state can be selected quickly.

  In the monitoring device 4 of the present embodiment, the user can easily grasp the installation position of the monitoring means that matches the aggregation conditions (first aggregation condition, second aggregation condition) set by the user. It is possible to quickly confirm the location in which the user is currently paying attention.

  Further, in the monitoring device 4 of the present embodiment, the second aggregation condition in the second display step is the monitoring means (the monitoring camera 2 and the image recording device 3 in the monitoring section selected in the first display step). ) Is automatically updated as a reflection of the first aggregation condition. For example, the state that is not currently generated as the state of the monitoring means (the monitoring camera 2 or the image recording device 3) in the selected monitoring section is updated so as to be automatically excluded from the first aggregation condition. By generating the aggregation condition (that is, the logical sum of the first aggregation condition and the current state of the selected monitoring section), the user can update the second condition in the second display step. By confirming the aggregation condition, it is possible to easily grasp the state of the monitoring means (the monitoring camera 2 and the image recording device 3) currently occurring in the monitoring section.

  The embodiments of the present invention have been described above by way of example, but the scope of the present invention is not limited to these embodiments, and can be changed or modified according to the purpose within the scope of the claims. is there.

  For example, in the above description, the example in which the monitoring section (monitoring property) is displayed in the area map in the first display process and the monitoring area (floor) is displayed in the thumbnail list in the second display process has been described. However, as shown in FIG. 8, the monitoring section may be displayed with a rectangular frame or the like in the first display step, and the monitoring area may be displayed with a rectangular frame or the like in the second display step. Also good.

  In the above explanation, an example where a single property includes a large number of floors such as a skyscraper or a large-scale shopping center has been described. However, a single property such as a convenience store has a small number of floors. In the case where only one property is included (for example, only one floor is included in one property), it is possible to handle a large number of properties as a single monitored property. That is, in the second display step, as shown in FIG. 9A, for each property, a plurality of monitoring areas (a plurality of monitoring areas included in one property) may be displayed in a thumbnail list. As shown in (b), a plurality of properties may be collected and a plurality of monitoring areas (a plurality of monitoring areas included in the plurality of properties) may be displayed in a thumbnail list.

  As described above, the monitoring device according to the present invention can easily check the status of the monitoring means in a predesignated state, and switches the display between the monitoring object map and the monitoring area plan view. When this is done, it has the effect of being able to take over the state specified by the user, and is useful for monitoring systems and the like.
