Description

[Technical Field]

[0001] The present disclosure relates to a technique for displaying observation data. [Background technology]

[0002] A system has been proposed that constantly observes the state of manufacturing equipment using a camera or the like attached to the equipment and accumulates the observation data (see, for example, Patent Document 1). In Patent Document 1, the observation data is stored together with the time when an event occurred. This makes it possible to read the observation data at the time an event occurred.

[0003] Factories in industries such as food, pharmaceutical, and automobile manufacturing use multiple pieces of equipment. If a malfunction occurs in one piece of equipment, it will affect the entire production line. For this reason, factory managers use a management system to centrally manage the operating status and events of the equipment within the factory via a communication network. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2021-152754 Summary of the Invention [Problem to be solved by the invention]

[0005] As a result of workforce reductions aimed at streamlining operations, the number of cameras and sensors monitoring the operation status of equipment has increased, making the management system more complex. As a result, when an event such as an alarm occurred, it was difficult to determine where the problem was, and it took a long time to determine the cause.

[0006] An object of the present disclosure is to enable intuitive understanding of the locations and number of events occurring in a managed object. [Means for solving the problem]

[0007] The management system of the present disclosure includes a plurality of sensors (22) and an information management device (91) of the present disclosure.

[0008] The information management device (91) of the present disclosure manages observation data observed at multiple different observation locations, and executes the information display method of the present disclosure, in which the information management device displays hierarchical information indicating the relationships between the observation locations, linked to the observation data.

[0009] The observation data may include events observed at the plurality of observation locations. The information management device may display, for each observation location, the number of notifications of the events observed at the plurality of observation locations.

[0010] A lower layer of the hierarchical information may be hidden. When the lower layer is hidden, the information management device may display a total number of notifications of the events in the lower layer on a layer above the lower layer.

[0011] The information management device may display the number of notifications of an event in any one of the hierarchical layers in the hierarchical information for each observation time of the event.

[0012] The information management device may send a request message to the multiple sensors to transmit information about the device using an HTTP (Hypertext Transfer Protocol) request, and may use responses from the multiple sensors to the HTTP request to determine the observation locations of the multiple sensors and construct the hierarchical information.

[0013] The above disclosures can be combined as much as possible. [Effects of the Invention]

[0014] According to the present disclosure, hierarchical information of the observation location is displayed in association with the observation data, making it possible to intuitively grasp the location of an event occurring in the managed object. Therefore, when an event such as an alarm occurs, the present disclosure makes it easy to understand where the problem lies and enables the cause to be quickly identified.

[0016] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Note that the present disclosure is not limited to the embodiments shown below. These implementation examples are merely illustrative, and the present disclosure can be implemented in various forms with various modifications and improvements based on the knowledge of those skilled in the art. Note that components with the same reference numerals in this specification and drawings indicate the same components.

[0017] (First embodiment) FIG. 1 shows an example of devices that are centrally managed by a management system. In a factory, a plurality of devices are used for each line. In the following embodiment, the management system is A and Factory F B This is an example of centralized management of Factory F.A Line L A and L B Equipped with Line L A Equipment D A ,D B ,D C Equipped with Line L B Equipment D D ,D E ,D F Factory F B Line L C and L D Equipped with Line L C Equipment D G ,D H Equipped with Line L D Equipment D I It is equipped with.

[0018] Equipment D A ~D I is equipped with observation equipment such as sensors and cameras. A ~D I Each observation device installed on the transmits observation data to the management system. A ~D I Any one or more pieces of information obtainable from the device D A ~D I Notification of events such as alarms observed on device D A ~D I Numerical data measured by equipment D A ~D I The management system may be configured to request each observation device to transmit observation data.

[0019] 2 shows an example of the configuration of an information management device of the present disclosure. The information management device 91 of this embodiment includes a communication unit 31 and a processing unit 32. The communication unit 31 communicates with each device D A ~D I The processing unit 32 stores the observation data in the information storage unit 14 and outputs information obtained from the observation data to the display unit 13. A ~D I The observation data from the satellite is displayed on the display unit 13.

[0020] The calculation processing unit 32 of the present disclosure executes the information display method of the present disclosure. Specifically, the calculation processing unit 32 executes the information display method of the present disclosure. A ~D I When displaying observation data, hierarchical information showing the relationship between observation sites is displayed in association with the observation data.

[0021] An example of the display is shown in FIG. 3. In this embodiment, the processing unit 32 A ~D I In this embodiment, the number of notifications of events related to device D is output. A ~D I The number of event notifications from device D A ~D I When displaying each device, A ~D I The hierarchical information is displayed. Specifically, the hierarchical information includes the factory F A and Factory F B is displayed, and the line L A , Line L B , Line L C、 Line L D is displayed, and device D is displayed on the third layer. A ~D I is displayed.

[0022] The calculation processing unit 32 displays the line L of the second layer so that it is clear to which layer it belongs. A and Line L B Factory F A and the second layer line L C and Line L D Factory F B Also, the third layer device D A ,D B ,D C Line L A and the third layer device D D ,D E ,D F Line L B and the third layer device D G ,D H Line L Cand the third layer device D I Line L D and connect.

[0023] The present disclosure displays hierarchical information on the display unit 13. By hierarchically organizing the hierarchical information in a structure similar to the actual factory configuration, it is possible to centrally manage notified events while eliminating the need to sort by location type such as factory, line, or equipment. Furthermore, the present disclosure makes it possible to see at a glance the relationship between the production line or equipment on which an event is occurring. This makes it possible to efficiently identify the cause and consider countermeasures.

[0024] When displaying hierarchical information, the calculation processing unit 32 may display the number of event notifications by hierarchical level, as shown in FIG. 3. By displaying the number of notifications, the number of events occurring in each process can be intuitively compared without checking the details. Therefore, the present disclosure can efficiently identify the cause of alarms and consider countermeasures in factories.

[0025] Here, the calculation processing unit 32 can collapse and hide the lower layer. For example, the line L in FIG. A When you select the line L, as shown in Figure 4. A Device D, which is a lower level A ~Equipment D C In addition, the factory F in Figure 3 can be hidden. A Select Factory F, as shown in Figure 5. A Line L, which is the hierarchy below A and L B can be hidden.

[0026] When the hierarchical information is folded, the calculation processing unit 32 displays the total number of notifications of the folded hierarchical information on the hierarchical level above the folded hierarchical level. For example, A The number of notifications is 20, and device D B The number of notifications is 15, and device D C The number of notifications is 14, and device D D The number of notifications is 5, and device D E The number of notifications is 4, and device D F The number of notifications is 15, and device D GThe number of notifications is 1, and device D H The number of notifications is 1, and device D I In the example shown in FIG. 4, when the number of notifications is 2, the calculation processing unit 32 calculates the line L A and Line L B In the example shown in Figure 5, the number of notifications is set to "49" and "24" for Factory F. A The number of notifications was 73, and Factory F B The number of notifications is set to 4. By displaying the total value of the collapsed hierarchy, it is possible to grasp the total number more efficiently.

[0027] 3 to 5, if the number of notifications exceeds a predetermined number, the calculation processing unit 32 may highlight the notification in red, for example. A If the number of notifications "73" exceeds a predetermined number, the calculation processing unit 32 A " or the number of notifications "73" is highlighted. This highlighting may be performed on each layer.

[0028] In this embodiment, the hierarchical information has hierarchical levels of factories, lines, and equipment, but the granularity of the hierarchical levels can be freely set. Furthermore, the observation data is not limited to factory observation data, and can be applied to various observation data in various industries.

[0029] (Second embodiment) Equipment D A ~D I Alternatively, the observation device mounted on these devices has a transmission function for transmitting set information. A ~D I The hierarchical information is automatically constructed using the transmission function provided by the system.

[0030] The information management device 91 of this embodiment uses the processing unit 32 and the communication unit 31 to send a request message to device D to request transmission of its own information. A ~D I At this time, the processing unit 32 and the communication unit 31 transmit a request message using an HTTP request. Here, the information of the device itself is transmitted to the device D.A ~D I is any information that can be acquired, for example, the MAC address of device D A ~D I Identification name of device D A ~D I Functions of equipment D A ~D I Manufacturer of Equipment D A ~D I This is the information set in Device D. A ~D I For example, the information set in device D A ~D I Examples of information on the installation location include:

[0031] Equipment D A ~D I When receiving the HTTP request, device D reads out its own information in accordance with the HTTP request and transmits it to the information management device 91. A ~D I may be performed, or equipment D A ~D I This may be done by observation equipment such as sensors and cameras mounted on the aircraft.

[0032] The communication unit 31 communicates with the device D in response to the HTTP request. A ~D I According to this embodiment, device D A ~D I or Device D A ~D I If the observation equipment installed in the device has the function to process HTTP requests, the information management device 91 will be A ~D I For example, device D A ~D I You can also get the manufacturer.

[0033] It should be noted that the information management device 91 does not send a request message, and device D A ~D I The management system may be constructed so that device D can voluntarily transmit its own information.A ~D I When the communication unit 31 of the information management device 91 receives the observation data, it extracts the information of its own device and sends it to the calculation processing unit 32.

[0034] The processing unit 32 is A ~D I Using the response from device D A ~D I The observation point of the line L is determined and hierarchical information is constructed. A and Factory F A Equipment like D A ~D I For information on the higher hierarchy, see Device D A ~D I Also, device D A ~D I The information management device 91 may transmit the location information of the device itself. A and Factory F B Location information, Line L A ~Line L D By referencing the table that manages the location information of device D, A ~D I From the location information of device D A ~D I It is possible to derive information at higher levels.

[0035] As described above, in the management system of this embodiment, the information management device 91 can automatically construct hierarchical information. In order to centrally manage information about a factory, it is necessary to register information about each piece of equipment in the factory in a database and link the information. Linking information in a way that allows for centralized management requires the collection of a large amount of information, which takes a great deal of time. Furthermore, if information collection and linking work are done manually, there is a risk of human error, and checking this takes a great deal of time. In this regard, this embodiment makes it possible to construct a highly reliable management system in a short amount of time.

[0036] (Third embodiment) FIG. 6 shows an example of the management system configuration of the present disclosure. In this embodiment, multiple sensors 22 are installed at the production site to be monitored, an event is detected based on the detection results of the multiple sensors 22, and an alarm is issued in response to the event. An information management device 91 aggregates and stores production information, alarms, and sensor information from production line equipment. The production information, alarms, and sensor information may be stored in a device other than the information management device 91, for example, in the information storage unit 14. The information management device 91 also generates a notification to be displayed on the display unit 13 based on the aggregated information. Furthermore, the information management device 91 displays the same information as the display unit 13 on terminals 94 located at the production site or in the control room.

[0037] The image synthesis unit 12 receives camera images from the production site and outputs the images to a display unit 13 installed in a control room. In this embodiment, the objects to be monitored are various machines at the production site. In this embodiment, multiple cameras 21 are installed at the production site to be monitored, and the images from the multiple cameras are included in the observation data.

[0038] In this embodiment, the image synthesizing unit 12 displays the images from the multiple cameras on the display unit 13 together with a notification from the information management device 91. At this time, the image synthesizing unit 12 synthesizes the images from the multiple cameras into display data so that the images from the multiple cameras can be displayed on a single display unit 13. The display data is data that can be displayed on the display unit 13, and an example of this is data in HDMI (registered trademark) (High-Definition Multimedia Interface) format.

[0039] 7 shows an example of display on the display unit 13. The images from the multiple cameras are displayed on the display unit 13, for example, by device D. A ~Equipment D I The image composition unit 12 may combine sensor information D1 to D4 detected by the sensor 22 with the plurality of camera images. The sensor information D1 to D4 may include numerical information detected by the sensor 22, time-series changes in the numerical information, or statistical information on the numerical information. The sensor information D1 to D4 may also be a graph of numerical values ​​detected by sensors mounted on the same monitored object.

[0040] The converter 15 converts the display data from the video composition unit 12 into video data in a predetermined format. For example, the converter 15 converts data in HDMI (registered trademark) format into data in H.264 / MPEG (Moving Picture Experts Group)-4 AVC (Advanced Video Coding) format. The video data from the converter 15 is stored in the information storage unit 14.

[0041] Video images from a plurality of cameras are stored as a single piece of video data in the information storage unit 14. Therefore, the management system of this embodiment makes it possible to check the video images from a plurality of cameras all at once.

[0042] An example of display on a web browser is shown in FIG. 8. The information management device 91 displays the monitored device D A ~Equipment D C Factory F A Line L is located at A The information management device 91 also displays, as hierarchical information, the fact that the device is used in the device D. A ~Equipment D C By configuring the information management device 91 to display on a web browser in this way, the same information as the display unit 13 can be displayed on a general-purpose terminal, making management at the production site easier.

[0043] Equipment D A When 20 events occur in the A When device D is selected, the information management device 91 A When the user selects one of the events displayed on the timeline TL, for example, an event at 13:00, the information management device 91 displays a timeline TL that displays the event occurrence times at device D on the time axis. AThe information management device 91 displays the details of the detected event and a snapshot of the video data displayed on the display unit 13 at the time the event occurred. In addition to the snapshot of the video stored in the information storage unit 14, the information management device 91 also displays the device D data stored in the information storage unit 14. A The event display method is not limited to the timeline TL, and events may be displayed in a list in the order in which they occurred.

[0044] Each snapshot displayed on the web browser may be linked to video data stored in the information storage unit 14, so that clicking on the snapshot will allow the video data to be played. For example, the video data for videos MA to MI may be playable for a certain period of time starting from 13:00. This allows the user to check what happened when an event occurred through video while also checking changes in the sensor information multiple times.

[0045] The information management device 91 may also display a timeline width setting slider TLS. The timeline width setting slider TLS has a function of increasing or decreasing the horizontal width of the grid of the timeline TL by changing the position of the slider. For example, moving the timeline width setting slider TLS to the right changes the grid of the timeline TL from every hour to every day. For example, moving the timeline width setting slider TLS to the left changes the grid of the timeline TL from every hour to every 10 minutes.

[0046] In Figure 9, line L A An example of the timeline TL display when is selected is shown below. A When this is selected, the information management device 91 A You can display the total number of event notifications, but the line L A Equipment D A , equipment D B , and Equipment D C The timeline TL of the number of notifications for the event may be displayed. AWhen the number of notifications exceeds a predetermined threshold, such as "10," the information management device 91 may highlight the number of notifications, for example, by displaying it in red.

[0047] (Other embodiments) The information management device 91 of the present invention can also be realized by a computer and a program, and the program can be recorded on a recording medium or provided via a network.

[0048] In the above embodiment, an example was shown in which the monitored site photographed by a camera is a production site, but the present disclosure can be applied to any monitored site where photography is constantly performed by a camera. Furthermore, in the above embodiment, an example was shown in which the event is an alarm, but the event in the present disclosure can be any event that can occur at the monitored site. Here, the sensor data includes any data that can detect the state of the monitored object, such as temperature and rotational torque, and includes log data that can be obtained from the monitored object.
