Description

Technical Field

[0001] The present invention relates to an information providing device, an information providing method and a computer-readable storage medium. Background Art

[0002] Currently, there is known a technology for efficiently managing data by collectively recording measurement results such as temperature, flow rate, and pressure measured by measuring instruments installed in a workshop and images captured by multiple cameras in one file (see, for example, Patent Document 1).

[0003] Patent Document 1: Japanese Patent No. 5979064

[0004] Hereinafter, the process of recording the measurement result and the image in one file is referred to as merging. Information of the merged file may be displayed on one screen. In the technology described in Patent Document 1, the measurement result and a plurality of images are displayed on one screen.

[0005] On the other hand, in the prior art, the visibility of data is sometimes reduced. For example, for a viewer of a screen (e.g., a manager of a workshop), not all of the multiple images displayed on one screen are necessary information. If unnecessary images are displayed on the screen for the viewer, it is difficult to observe the screen and obtain the necessary information efficiently. Summary of the invention

[0007] An information providing device involved in one aspect is characterized in that it has: a selection unit, which selects greater than or equal to one image data associated with a plurality of image data when a predetermined condition is met; and a display control unit, which causes one screen to simultaneously display measurement data measured by a measuring device when the condition is met, and image data selected by the selection unit.

[0008] An information providing method involved in one aspect is characterized in that the information providing method causes a computer to perform the following processing: when a predetermined condition is met, one or more image data associated with the condition is selected from a plurality of image data, and one screen simultaneously displays the measurement data measured by the measuring device when the condition is met and the selected image data.

[0009] One aspect involves a computer-readable recording medium that records an information providing program, characterized in that the information providing program causes a computer to perform the following processing: when a predetermined condition is met, one or more image data associated with the condition is selected from a plurality of image data, and one screen simultaneously displays the measurement data measured by a measuring device when the condition is met and the selected image data.

[0023] Below, the information providing device, information providing method and computer-readable storage medium disclosed in the present application are described in detail based on the accompanying drawings. In addition, the invention of the present application is not limited by the embodiments described here. In addition, the same reference numerals are marked on the same elements and repeated descriptions are appropriately omitted. In addition, each embodiment can be appropriately combined within the scope of non-contradiction.

[0024] The information providing device of this embodiment provides data obtained by combining measurement data obtained by a measuring instrument installed in a plant or other facility and image data captured by a camera. The image may be a still image or a moving image.

[0025] Figure 1 1 is a diagram showing a configuration example of an information providing system according to a first embodiment. The information providing system 1 includes a server 10, a terminal device 20, a plurality of cameras (camera 30_1, camera 30_2, ..., camera 30_n), and a measuring device 40. Here, n is the number of cameras. In addition, m is the number of channels for measuring data. The number of cameras and the number of channels for measuring data are not limited to the numbers shown in the figure. For example, n is greater than or equal to 2. The server 10 is an example of an information providing device.

[0026] The channel may correspond to a location where an object to be measured by the measuring device 40 exists. In addition, the channel may correspond to a plurality of measuring devices 40, respectively.

[0027] The server 10 acquires data of images captured by the plurality of cameras (hereinafter referred to as image data) and acquires measurement data measured by the measuring device 40 for each of the plurality of channels.

[0028] For example, the measuring device 40 is a sensor for measuring a physical quantity of a plant equipment installed in a plant. The plant equipment is a container, a pipe, a furnace, etc. In addition, the physical quantity is temperature, pressure, flow rate, etc.

[0029] The server 10 periodically acquires and stores the acquired image data and measurement data in advance. In addition, the server 10 may be provided in a workshop where the measuring device and the camera are installed. In this case, the server 10 is connected to a plurality of cameras, the measuring device 40, and the terminal device 20 via a network such as Ethernet (registered trademark) installed in the workshop.

[0030] Alternatively, the server 10 may be a cloud server connected to devices in a workshop using the Internet or the like.

[0031] The server 10 includes a selection unit 11 and a display control unit 13. The server 10 also stores setting information 12.

[0032] The selection unit 11 selects image data to be merged from a plurality of image data based on a condition (hereinafter referred to as a trigger condition). The setting information 12 is information that associates the trigger condition with a camera that captures the image data to be merged.

[0033] The display control unit 13 generates a display data file by combining the measurement data and the image data selected by the selection unit 11. The display control unit 13 provides the generated display data file to the terminal device 20. For example, the display data file is an HTML file.

[0034] The terminal device 20 includes a conversion unit 21 and a display unit 22. The conversion unit 21 converts a display data file into a displayable format using an application program installed in the terminal device 20.

[0035] The terminal device 20 functions as a viewer for viewing the display data file provided from the server 10. On the other hand, the server 10 functions as a recorder for recording measurement data and image data and providing the data that can be viewed by the viewer.

[0036] The display unit 22 is a display device such as a monitor that displays a screen based on the converted display data file.

[0037] Here, the number of image data included in the display data file and the camera that captured the image data differ according to the selection result obtained by the selection unit 11. That is, the number and content of images in the screen displayed on the display unit 22 differ according to the trigger condition.

[0038] exist Figure 2 An example of a screen displayed by the display unit 22 is shown in FIG. Figure 2 The screen 221a displays the image data 300_1, the image data 300_2, and the measurement data 400_1. In this case, the selection unit 11 has selected both the image data 300_1 and the image data 300_2. In addition, the horizontal axis of the measurement data is time. Figure 2 As shown in FIG. 1 , the time of the measurement data 400_1 corresponding to the image data 300_1 and the image data 300_2 is represented by a connecting line. Figure 3 As shown in FIG. 1 , a plurality of image data (in this case, both image data 300_1 and image data 300_2) can be associated with one moment. Figure 2 and Figure 3 When the slide bar 401_1 of the measurement data 400_1 is operated, a portion corresponding to the range of time corresponding to the position of the slide bar 401_1 of the measurement data 400_1 is displayed.

[0039] On the other hand, Figure 4The screen 221b displays the image data 300_1 and the measurement data 400_1. In this case, the selection unit 11 selects only the image data 300_1. Figure 4 In the example, Figure 2 and Figure 3 Different from , the selected image data is 1, so there is only 1 connecting line. Figure 4 In, also with Figure 2 and Figure 3 Similarly, when the slide bar 401_1 is operated, a portion corresponding to a range of time corresponding to the position of the slide bar 401_1 of the measurement data 400_1 is displayed.

[0040] It can be considered that the image data required by the viewer is different depending on the trigger condition. For example, if it is considered that the viewer needs image data 300_1 but not image data 300_2, the server 10 provides a display data file for displaying screen 221b instead of screen 221a. In this way, the server 10 can reduce the file size of the display data file and improve the visibility of the data.

[0041] Next, a specific example of the setting information 12 is described. The server 10 can select image data using each trigger condition alone, or can select image data by combining multiple trigger conditions. In addition, the trigger condition described here can be referred to when an alarm is generated. For example, the server 10 can refer to the setting information 12 when an alarm is generated, and select image data corresponding to the trigger condition. The alarm is generated, for example, when the measurement value measured by the measuring device 40 exceeds a threshold value.

[0042] [Trigger conditions based on tag number]

[0043] Figure 5 2 is a diagram showing an example of a trigger condition based on a label number. The label number corresponds to a channel, for example.

[0044] Tag numbers "0001", "0002" and "0003" are respectively Figure 1 The measurement data 400_1, the measurement data 400_2 and the measurement data 400_3 (not shown) correspond to each other.

[0045] exist Figure 5 In the example, when the measurement value indicated by the measurement data 400_1 corresponding to the tag number "0001" exceeds the threshold value (when an alarm is generated), the selection unit 11 selects the image data 300_1 captured by the camera 30_1. In addition, generating an alarm is an example of a condition related to the measurement data.

[0046] [Trigger conditions based on group number]

[0047] Figure 6 FIG. 4 is a diagram showing an example of a trigger condition based on a group number. Figure 6 As shown, a plurality of label numbers can be grouped. For example, group A includes label numbers "0001" and "0002".

[0048] exist Figure 6 In the example, when the measurement values ​​shown in the measurement data 400_1 or the measurement data 400_2 corresponding to the tag numbers "0001" and "0002" included in group A exceed the threshold value (when an alarm is generated), the selection unit 11 selects the image data 300_1 captured by the camera 30_1.

[0049] In addition, if Figure 6 As shown, with respect to the trigger condition, a plurality of measurement data can be associated with one image data. Also, with respect to the trigger condition, a plurality of measurement data can be associated with a plurality of image data.

[0050] In addition, Figure 5 and Figure 6 In the example of , the display control unit 13 can merge the measurement data indicated by the conditions and the image data selected by the selection unit 11.

[0051] In this way, when a condition such as an alarm is generated for a specific measurement data of one or more measured data measured by the measuring device is satisfied, the selection unit 11 selects one or more image data associated with the specific measurement data of one or more measured data. Thus, the selection unit 11 can select image data including information related to the measurement data for which the alarm is generated.

[0052] [Trigger conditions based on time]

[0053] Figure 7 This is a diagram showing an example of a trigger condition based on time. For example, time periods such as "0:00-8:00", "8:00-16:00", and "16:00-24:00" are associated with image data.

[0054] exist Figure 7 In the example, when the measurement value indicated by any measurement data at time "7:00" exceeds the threshold value (when an alarm is generated), the selection unit 11 selects the image data 300_1 captured by the camera 30_1 as the image data corresponding to the period "0:00-8:00" including the time "7:00".

[0055] Thus, when the condition that the measurement data is measured by the measuring device in a specific time period is satisfied, the selection unit 11 selects one or more image data associated with the specific time period. Thus, the selection unit 11 can select image data containing useful information, for example, by considering the time period of plant equipment operation.

[0056] For example, it can be considered that even if image data photographing a certain shop equipment is selected during a time period when the shop equipment is not in operation, useful information cannot be obtained. On the other hand, by associating the operation time period of the shop equipment with the image data photographing the shop equipment in advance, the selection unit 11 can select image data including useful information related to the shop equipment.

[0057] [Trigger conditions based on external signals]

[0058] Figure 8 1 is a diagram showing an example of a trigger condition based on an external signal. The selection unit 11 can select image data based on an external signal. The external signal is a signal that the server 10 can obtain separately from the measurement data. The external signal is provided, for example, from a monitoring system that monitors a workshop.

[0059] exist Figure 8 In the example of FIG. 1 , when the server 10 receives the signal X, the selection unit 11 selects the image data 300_1 captured by the camera 30_1 .

[0060] Thus, when the information providing device receives a specific signal, the selection unit 11 selects one or more image data associated with the specific signal. Thus, even when an alarm for the measurement data is not generated, the selection unit 11 can select image data containing important information based on the external signal.

[0061] [Trigger conditions based on alarm level]

[0062] Fig. 9 2 is a diagram showing an example of a trigger condition based on an alarm level. For example, the alarm level is defined according to the importance of an event that causes an alarm.

[0063] For example, the measurement data indicates the temperature of a certain liquid measured by a temperature sensor. Level 1 is the alarm level when the temperature indicated by the measurement data is 100°C to 150°C. Level 2 is the alarm level when the temperature indicated by the measurement data is 150°C to 200°C. Level 3 is the alarm level when the temperature indicated by the measurement data is greater than or equal to 200°C.

[0064] The greater the alarm level, the greater the importance of the event. In addition, the greater the importance of the event, the greater the damage and cost of goods, personnel or economic aspects caused by the event.

[0065] exist Fig. 9 In the example of , when the alarm level is level 1, the selection unit 11 selects the image data 300_1 captured by the camera 30_1. In addition, when the alarm level is level 2, the selection unit 11 selects the image data 300_2 and the image data 300_3 captured by the camera 30_2 and the camera 30_3. In addition, when the alarm level is level 3, the selection unit 11 selects the image data 300_1, the image data 300_2, and the image data 300_3 captured by the camera 30_1, the camera 30_2, and the camera 30_3.

[0066] In this way, when the condition for generating an alarm of a specific level for a specific measurement data measured by the measuring device is satisfied, the selection unit 11 selects a specific image data associated with the level. Thus, the selection unit 11 selects image data from which information of a quantity corresponding to the level of the alarm, that is, the importance, can be obtained.

[0067] For example, when the measurement data indicates the temperature of a liquid as described above, the camera 30_1 captures an image of a container of the liquid. Also, for example, the camera 30_2 captures an image of a heater for heating the liquid. Also, for example, the camera 30_3 captures an image of a control device for controlling the intensity of heating by the heater.

[0068] In this case, when the alarm level is level 3, which is particularly important, the viewer can confirm the status of the container, the heater, and the control device and find out the cause of the event more reliably.

[0069] [Modification: Selecting image data using the rate of increase in measured values]

[0070] The selection unit 11 may select image data based on the time-series increase rate of the measurement value indicated by the measurement data.

[0071] First, the selection unit 11 measures the period required for the measurement value indicated by the measurement data to increase from the value corresponding to the alarm level 1 to the value corresponding to the alarm level 2. Then, if the value corresponding to the alarm level 1 is V1, the value corresponding to the alarm level 2 is V2, and the period is t, the selection unit 11 calculates the increase rate as (V2-V1) / t.

[0072] For example, when the rise rate is less than the threshold value (t is longer), the selection unit 11 selects the image data 300_1. On the other hand, when the rise rate is greater than or equal to the threshold value (t is shorter), the selection unit 11 selects the image data 300_2. That is, the image data is associated with the rise rate. The image data 300_1 is associated with a rise rate less than the threshold value. The image data 300_2 is associated with a rise rate greater than or equal to the threshold value.

[0073] It can be considered that the greater the rate of increase, the greater the importance of the event. For example, if the temperature and pressure of a container increase rapidly, it may lead to a serious accident such as container damage.

[0074] The selection unit 11 assigns and stores the measurement date and time to the selected image data in advance in time series. The selection unit 11 compares the image data assigned in time series and selects image data with a large difference (change over time).

[0075] For example, the selection unit 11 compares the image data assigned at each time with the image data assigned at an adjacent time, and calculates a difference. For example, the difference between the image data is the total value of the difference in pixel value of each pixel.

[0076] Furthermore, the selection unit 11 may select image data captured by a camera that has been set in accordance with the trigger condition, and may not select image data captured by a camera that corresponds to the trigger condition.

[0077] For example, the camera settings include the zoom factor of the camera used for shooting, switching of the actual image or temperature recorder, switching of the light on / off, and the like.

[0078] In this way, when the condition that the measurement data measured by the measuring device increases at a specific increase rate is satisfied, the selection unit 11 selects image data whose magnitude of time series change is greater than or equal to a threshold value from the time series image data associated with the increase rate. Thus, the selection unit 11 can select image data that reveals the cause of the increase in the measurement data.

[0079] use Fig.10 The processing flow of the server 10 will be described. Fig.10 This is a flowchart showing the flow of the information provision process (server 10 ) according to the first embodiment.

[0080] like Fig.10 As shown, first, the server 10 receives the setting of the trigger condition and the selected image data (steps S101 and S102). Here, the server 10 starts recording the measurement data and the image data (step S103).

[0081] Next, the server 10 records the measurement data and the image data in parallel (step S2). The server 10 acquires the measurement data measured by the measuring device 40 (step S104), and saves the acquired measurement data (step S105). In addition, the server 10 acquires the image data captured by the plurality of cameras (step S106), and saves the acquired image data (step S107).

[0082] When the trigger condition set in step S101 occurs (Yes in step S108), the server 10 selects image data corresponding to the trigger condition (step S109). The server 10 then stores a display data file in which the measurement data and the selected image data are combined (step S110).

[0083] If the trigger condition is not generated (step S108, No), or if the processing of step S110 is completed, the server 10 determines whether the recording of the measurement data and the image data is completed (step S111). For example, if a predetermined time has passed since the start of recording (step S103), it is determined that the server 10 has completed recording.

[0084] When recording is not completed (step S111 , No), the server 10 returns to step S2 and repeats the process.

[0085] When recording is completed (step S111 , Yes), the server 10 outputs the display data file to the terminal device 20 (step S112 ).

[0086] Then, the server 10 causes the terminal device 20 to convert the display data file (step S113 ), and simultaneously display the measurement value data and the image data (step S114 ).

[0087] [Effect]

[0088] As described above, the server 10 includes the selection unit 11 and the display control unit 13. When a preset condition is satisfied, the selection unit 11 selects one or more image data associated with the condition from a plurality of image data. The display control unit 13 displays the measurement data measured by the measuring device when the condition is satisfied and the image data selected by the selection unit 11 on one screen at the same time.

[0089] In this way, the server 10 selects necessary image data according to the conditions, combines it with the measurement data, and displays it on one screen, thereby reducing the size of the combined data and improving the visibility of the data on the screen.

[0090] [system]

[0091] The information including the processing sequence, control sequence, specific names, various data, and parameters shown in the above description and drawings can be arbitrarily changed unless otherwise specified.

[0092] In addition, the structural elements of each device shown in the figure are functional concepts and do not necessarily need to be physically configured as shown in the figure. In other words, the specific method of distributing and integrating each device is not limited to the method shown in the figure. In other words, the whole or part of the devices can be functionally or physically distributed or integrated in any unit according to various loads, usage conditions, etc.

[0093] Furthermore, all or any part of each processing function performed by each device may be realized by a CPU and a program analyzed and executed by the CPU, or may be realized as hardware based on wired logic.

[0094] [hardware]

[0095] Next, a hardware configuration example of the server 10 will be described. Fig.11 This is a diagram for explaining an example of a hardware configuration. Fig.11 As shown, the server 10 has a communication device 100a, a HDD (Hard Disk Drive) 100b, a memory 100c, and a processor 100d. Fig.11 The various parts shown are connected to each other by a bus or the like.

[0096] The communication device 100a is a network interface card, etc., and performs communication with other servers. Figure 1 The functions shown are stored in the program and DB that execute the actions.

[0097] The processor 100d reads and executes data from the HDD 100b or the like. Figure 1 The same processing program is developed in the memory 100c, thereby executing Figure 1 The process of each function described in the above etc. executes the action. For example, this process executes the same function as each processing unit of the server 10. Specifically, the processor 100d reads a program having the same function as the collection unit 151, the evaluation unit 152, and the display control unit 153 from the HDD 100b etc. Then, the processor 100d executes the following process, that is, executes the same processing as the collection unit 151, the evaluation unit 152, and the display control unit 153.

[0098] In this way, the server 10 acts as an information providing device that executes the information providing method by reading and executing the program. In addition, the server 10 can also realize the same functions as the above-mentioned embodiment by reading the above-mentioned program from the recording medium using a medium reading device and executing the above-mentioned program. In addition, the programs mentioned in other embodiments are not limited to being executed by the server 10. For example, when other computers or servers execute the program, or when they cooperate to execute the program, the present invention can also be applied in the same way.

[0099] The program can be distributed via a network such as the Internet. In addition, the program can be recorded on a computer-readable recording medium such as a hard disk, a floppy disk (FD), a CD-ROM, an MO (Magneto-Optical disk), or a DVD (Digital Versatile Disc), and read from the recording medium by a computer for execution.
