[0015] The equipment E in the workshop 10 has a function of recording data indicating the operation history of the equipment E on various recording media. Each equipment E may be equipped with a communication device that can connect to the communication network 13 and transmit the recorded data to the outside. Each equipment E or its communication device may be included in the present system 1.

[0016] In this system 1, each camera 11 is arranged to capture an area including different pieces of equipment E, for example, in a workplace 10. Each camera 11 is communicatively connected to a traffic line management server 11 via a communication network 13, for example, so as to be able to transmit video data D0 of the captured images of the workplace 10. The camera 11 may be, for example, an omnidirectional camera or a box camera.

[0017] The flow line management server 12 is a server device equipped with a storage unit and the like that accumulates and manages information such as video data D0 captured by each camera 11 and flow line data D1 that indicates various flow lines based on the video data D0. The flow line management server 12 may further manage data on the operating status of equipment E in the workplace 10.

[0018] The information analysis device 2 according to this embodiment presents information for the user 15 to analyze from information accumulated in the system 1, such as video data D0 and flow line data D1. The information analysis device 2 is configured with an information processing device such as a PC (personal computer). The configuration of the information analysis device 2 will be described with reference to FIG. 2.

[0019] 1-2.Configuration of information analysis device Fig. 2 is a block diagram illustrating an example of the configuration of the information analysis device 2.

[0023] The storage unit 21a stores parameters, data, control programs, etc. for realizing predetermined functions. The storage unit 21a is configured, for example, with an HDD or SSD. For example, the storage unit 21a stores the above-mentioned programs, as well as map information D2 and equipment operation data D3, etc. The map information D2 indicates, for example, the location of each piece of equipment E in the workshop 10 in a predetermined coordinate system. The equipment operation data D3 indicates the history of the operating status of each piece of equipment E in the workshop 10. Details of the various types of data will be described later.

[0024] The temporary storage unit 21b is configured with a RAM such as a DRAM or an SRAM, and temporarily stores (i.e., holds) data. For example, the temporary storage unit 21b holds the flow line data D1 and video data D0 received from the flow line management server 12 (FIG. 1), as well as various timelines (described later). The temporary storage unit 21b may also function as a work area for the control unit 20, and may be configured as a storage area in the internal memory of the control unit 20.

[0025] The operation unit 22 is a general term for operation members operated by the user. The operation unit 22 may be, for example, a keyboard, a mouse, a touchpad, a touch panel, a button, a switch, etc. The operation unit 22 is an example of an input unit that acquires various information input by a user's operation.

[0026] The display unit 23 is an example of an output unit configured, for example, by a liquid crystal display or an organic EL display. The display unit 23 may display various information such as various icons for operating the operation unit 22 and information input from the operation unit 22.

[0027] The device I / F 24 is a circuit for connecting an external device to the information analysis device 2.

[0028] The network I / F 25 is a circuit for connecting the information analysis device 2 to the communication network 13 via a wireless or wired communication line. The network I / F 25 performs communication in accordance with a predetermined communication standard. The predetermined communication standard includes communication standards such as IEEE802.3, IEEE802.11a / 11b / 11g / 11ac, etc. The network I / F 25 may constitute an input unit that receives or an output unit that transmits various information via the communication network 13 in the information analysis device 2.

[0029] The above-described configuration of the information analysis device 2 is merely an example, and the configuration of the information analysis device 2 is not limited to this. For example, the information analysis device 2 may be configured as various computers including a server device. The information analysis device 2 may be configured integrally with the path management server 12.

[0030] The input unit in the information analysis device 2 may be realized in cooperation with various software in the control unit 20, etc. The input unit in the information analysis device 2 may acquire various pieces of information by reading out the various pieces of information stored in various storage media (for example, the storage unit 21a) into a working area of ​​the control unit 20 (for example, the temporary storage unit 21b).

[0031] Various display devices such as a projector and a head-mounted display may be used for the display unit 23 of the information analysis device 2. When an external display device is used, the display unit 23 of the information analysis device 2 may be an output interface circuit for a video signal or the like that complies with the HDMI (registered trademark) standard, for example.

[0032] 1-2-1. Data structure The structures of various data stored in the information analysis device 2 and the like in this system 1 will be described with reference to FIGS.

[0033] FIG. 3 is a diagram illustrating the flow line data D1 in the present system 1. The flow line data D1 includes, for example, a flow line ID, time information, and position information, which are associated with each other. The flow line ID indicates an identification number for each individual flow line. The time information is represented, for example, by a frame number of the corresponding video data D0. The position information indicates the position of a moving object, such as a worker W, in the coordinate system (X, Y) of the map information D2.

[0034] FIG. 4 is a diagram illustrating map information D2 in this system. The map information D2 illustrated in FIG. 4 includes, in a coordinate system (X, Y) preset for the workplace 10, the ranges of multiple pieces of equipment E1 to E4 arranged in the workplace 10 and the coordinate positions of work areas R1 to R4 corresponding to the pieces of equipment E1 to E4, respectively. Hereinafter, the equipment E1 to E4 will be collectively referred to as equipment E, and the work areas R1 to R4 will be collectively referred to as work area R. Each work area R is an area where one or more workers W are expected to work on the corresponding piece of equipment E, and is set, for example, within the imaging range of a separate camera 11. Furthermore, while FIG. 4 illustrates four pieces of equipment E1 to E4, the number of pieces of equipment E in the workplace 10 is not particularly limited and may be greater. Furthermore, the number of pieces of equipment E may be three or less.

[0035] 5 is a diagram illustrating equipment operation data D3 in the present system 1. The equipment operation data D3 includes, for example, identification information of equipment E, time information including start and end times, and a status indicating the operation state, all of which are associated with one another. For example, a user 15 of the information analysis device 2 records operation data for each equipment E in advance on a portable recording medium (e.g., a memory card) or the like, and inputs the data from the recording medium to the information analysis device 2 via the device I / F 24 or the like. In this way, the information analysis device 2 obtains the equipment operation data D3.

[0036] 2.Operation The operations of the traffic line analysis system 1 and the information analysis device 2 configured as above will be described below.

[0037] 2-1. System operation In the traffic flow analysis system 1 (Figure 1) of this embodiment, for example, multiple cameras 11 sequentially capture frame by frame the work area R in each imaging range when each piece of equipment E in the workplace 10 is operating, and transmit the video data D0 to the traffic flow management server 12.

[0038] The flow line management server 12 receives the video data D0 from each camera 11 and stores it in a memory unit of the flow line management server 12. In addition, the flow line management server 12 performs image recognition to recognize the position of the worker W in the captured image for each frame indicated by the video data D0 from each camera 11, generates flow line data D1, and stores it in a memory unit.

[0039] The information analysis device 2 acquires data indicating the operating status of each piece of equipment E at the time of imaging by the system 1, for example, from various I / Fs 24, 25 (FIG. 2), and stores the data in the memory unit 21 as equipment operation data D3. The information analysis device 2 also performs data communication with the flow line management server 12, and receives various pieces of information from the flow line management server 12 in response to, for example, an operation by the user 15. Based on the information acquired as described above, the information analysis device 2 generates various pieces of information that the user 15 uses to analyze the workplace 10, and displays the information on the display unit 23. An example of this is shown in FIG. 6.

[0040] Fig. 6 is a diagram illustrating timelines 5 and 6 in the information analysis device 2. Fig. 6 displays an operation timeline 5 for one piece of equipment E1 and a stay timeline 6 for a work area R1 corresponding to the equipment E1. Each of the timelines 5 and 6 shows information to be analyzed in chronological order.

[0041] The operation timeline 5 is an example of operation information that shows the past operation status of each piece of equipment E in sections on a time axis. For example, the operation timeline 5 is configured by sequentially arranging a normal operation section 51, an error stop section 52, and a standby section 53 along the time axis. The normal operation section 51 is a time section showing a state in which the equipment E was operating normally. The error stop section 52 is a time section showing a state in which the equipment E was stopped due to an error or the like. The standby section 53 is a time section showing a state in which the equipment E was on standby for switching work, preparation, or the like. In FIG. 6, areas with the same hatching as each time section marked with the symbols 51, 52, and 53 indicate the same type of time section. In the operation timeline 5, the various time sections 51 to 53 are displayed, for example, by using different colors to distinguish them from one another.

[0042] The stay timeline 6 is an example of detection information that indicates, by time interval, the detection results of a stay status, such as the presence or absence of a worker W in a corresponding work area R. For example, the stay timeline 6 includes a stay interval 61 and an absence interval 62. The stay interval 61 is a time interval in which the presence of one or more workers W is detected in the work area R. The absence interval 62 is a time interval in which the presence of a worker W is not detected in the work area R. In FIG. 6, areas with the same hatching as the time intervals marked with the symbols 61 and 62 indicate the same type of time interval. In the stay timeline 6, the various time intervals 61 and 62 are displayed, for example, by different colors to distinguish them from one another.

[0043] The stay timeline 6 constitutes link information for, for example, video data D0 showing the imaging results of the corresponding work area R. Such video data D0 is an example of predetermined information related to the stay timeline 6.

[0044] According to the timelines 5 and 6 as described above, the operating status of the equipment E and the status of the worker W in the corresponding work area R are visualized in chronological order, which is useful for analyzing, for example, the work efficiency of the equipment E. In this embodiment, a user interface is provided that can efficiently analyze the timelines 5 and 6 as described above for a large number of pieces of equipment E and work areas R in the workplace 10.

[0045] 2-2. Timeline analysis screen The analysis screen displaying the timelines 5 and 6 in the information analysis device 2 of this embodiment will be described with reference to FIG.

[0046] 7(A) and (B) show display examples of the timelines 5 and 6 before and after filtering in the information analysis device 2. Hereinafter, the horizontal coordinate H on the analysis screen displayed by the display unit 23 of the information analysis device 2 will be referred to as the H coordinate, and the vertical coordinate V on the analysis screen will be referred to as the V coordinate. In addition, in these image coordinates (H, V), the +V side may be referred to as the upper side, and the -V side may be referred to as the lower side.

[0047] 7(A) and (B), operation timelines 5 and stay timelines 6 relating to various pieces of equipment E and their work areas R are arranged side by side in a vertical direction V, with their time axes aligned with a horizontal direction H. In addition, in this display example, a scroll bar 40 is provided for sequentially displaying timelines 5 and 6 that do not fit within the displayable range of the analysis screen, starting from the top. The scroll bar 40 has a movable range that can be slid according to the number of timelines 5 and 6 to be displayed, and accepts user operations, i.e., slide operations, to sequentially slide the timelines 5 and 6 to be displayed.

[0048] The analysis screen shown in Fig. 7(A) is an overall display of a predetermined period, such as one day, and includes timelines 5 and 6 for all equipment E in the workplace 10 as display targets. For example, a pair of an operation timeline 5 and a stay timeline 6 is arranged sequentially for each piece of equipment E. In the example of Fig. 7(A), since there are many timelines 5 and 6 to be displayed, the range of movement of the scroll bar 40 is set to be relatively wide.

[0049] For example, when analyzing a bottleneck in the workplace 10, the user 15 may want to analyze a worker W or the like who stayed in a work area R of another piece of equipment E in an error stop section 52 of another piece of equipment E. In such a case, on the overall display analysis screen ( FIG. 7(A) ), the user 15 would have to repeatedly slide across multiple timelines 5 and 6 to sequentially check whether or not the worker W is in each work area R, which would be cumbersome. Therefore, it is conceivable that the burden on the user 15 when performing the desired analysis would be excessive if only the analysis screen described above were used.

[0050] Therefore, the information analysis device 2 of this embodiment accepts an operation by the user 15 to specify a time interval of the equipment E that the user 15 wants to analyze, for example, on the operation timeline 5 on the analysis screen being displayed, and performs filtering to limit the timelines 5 and 6 to be displayed. Fig. 7(B) shows an example of the analysis screen displayed as a filtering result by the information analysis device 2.

[0051] FIG. 7(B) shows an example of a display of a filtering result when a time interval 50, such as a specific error stop interval 52 (FIG. 6) in a specific facility E3, is specified by a user operation in the display example of FIG. 7(A). As an example of filtering based on such a specification operation of the operation timeline 5, the information analysis device 2 narrows down the display by excluding operation timelines 5 of facilities E other than the specified facility E3. In this way, by reducing information that is not expected to be the target of analysis for the user 15 and aggregating and displaying information that may be the target of analysis, the analysis load can be reduced. Furthermore, in this embodiment, the analysis load can also be easily reduced by restricting the display of the stay timeline 6 by rearranging the display order or narrowing down the display targets.

[0052] 2-3. Operation of the information analysis device The operation of the information analyzing device 2 that provides the above-described user interface will be described with reference to FIGS.

[0053] 8 is a flowchart illustrating the operation of the information analysis device 2. The processing shown in the flowchart in FIG. 8 is started, for example, when the equipment operation data D3 and the like have been acquired, and is executed by the control unit 20 of the information analysis device 2.

[0054] First, the control unit 20 of the information analysis device 2 generates an operation timeline 5 for all of the equipment E based on the equipment operation data D3 for a predetermined period (S1). The predetermined period is a period set in advance as a display target, such as the past day.

[0055] The control unit 20 also generates a stay timeline 6 for all work areas R, for example, based on the flow line data D1 and map information D2 (S1). For example, the control unit 20 acquires flow line data D1 for the same period as the operation timeline 5 from the flow line management server 12. The control unit 20 detects, for example, the position coordinates included in each work area R in the acquired flow line data D1 for each time, and generates a stay timeline 6 for that work area R. The control unit 20 stores the generated various timelines 5, 6 in the storage unit 21.

[0056] Next, the control unit 20 displays an analysis screen for overall display on the display unit 23 based on the generated timelines 5 and 6, for example, as shown in Fig. 7(A) (S2). The control unit 20 accepts user operations for each of the timelines 5 and 6 displayed on the display unit 23 via the operation unit 22 (S3, S5). The user operations targeted in steps S3 and S5 are, for example, clicking with the pointer 41 to specify a desired position on the timeline 5 or 6.

[0057] For example, when a designation operation for the operating timeline 5 is input (YES in S3), the control unit 20 executes a process of filtering the timelines 5 and 6 (S4). In the filtering process for the timelines 5 and 6 (S4), for example, the timelines 5 and 6 to be displayed are narrowed down or the display order is controlled, thereby limiting the display targets on the analysis screen to the filtering results, as shown in Fig. 7(B). The process of step S4 will be described in detail later.

[0058] Furthermore, when a designation operation for a stay timeline 6 is input (YES in S5), the control unit 20 causes, for example, an image of the working area R corresponding to the designated stay timeline 6 to be displayed on the display unit 23 (S6). An example of the display in step S6 is shown in FIG.

[0059] In the example of Fig. 9, the display unit 23 displays video captured around a specific time in the work area R2 of the facility E2 corresponding to the stay timeline 6 specified in Fig. 7(B). For example, in the operation of specifying the stay timeline 6 (S5), the control unit 20 identifies the work area R2 and time corresponding to the specified stay timeline 6 based on the image coordinates (H, V) input with the pointer 41. The control unit 20 receives video data D0 of the work area R corresponding to the specified stay timeline 6 from, for example, the flow line management server 12, and displays the video at the identified time (S6).

[0060] In the example of FIG. 9, the image capture result of worker W, whose presence was detected, can be confirmed from the video in the stay timeline 6 corresponding to the video. Such video is an example of related information associated with the stay timeline 6. The video displayed in step S6 may be a video or a still image. For example, when displaying video by specifying the stay timeline 6 as described above (S5, S6), the timeline filtering process (S4) can efficiently present stay timelines 6 that are candidates for video display (see FIG. 7(B)).

[0061] Furthermore, the user 15 may again perform a designation operation on the operation timeline 5 (NO in S5, YES in S3) before performing a designation operation on the displayed stay timeline 6, for example, on the analysis screen of the filtering result (FIG. 7(B)). For example, the user 15 may further designate a time interval on the operation timeline 5 that is different from the time interval already designated the first time, as the second designation operation on the operation timeline 5. In this case, the control unit 20 may again perform the process of step S4 on the timelines 5 and 6 to be displayed that were limited the first time, to further limit the display targets.

[0062] The control unit 20 causes the display unit 23 to display the video (S6), for example, and ends the processing shown in this flowchart.

[0063] According to the above processing, when displaying, for example, an image of the working area R corresponding to the stay timeline 6 (S6), the timeline filtering processing (S4) makes it easier for the user 15 to find the stay timeline 6 corresponding to the image that the user wants to view.

[0064] 2-3-1. Timeline Filtering Details of the processing of step S4 in Fig. 8 will be described with reference to Fig. 10. Below, as an example of the timeline filtering process (S4), an example will be described in which the stay of worker W is used as a condition for narrowing down the display targets, and the movement between work areas R1 to R4 is used as a condition for setting the display order.

[0065] 10 is a flowchart illustrating the timeline filtering process (S4 in FIG. 8) performed by the information analysis device 2 of this embodiment. The process of this flow is executed by the control unit 20 of the information analysis device 2 when, for example, a designation operation for the operating timeline 5 is performed (YES in S3) while the analysis screen illustrated in FIG. 7(A) is displayed.

[0066] First, the control unit 20 inputs (S11) information indicating the equipment E and the time interval 50 specified in the specification operation (S3 in FIG. 8) on the operation timeline 5 from the operation unit 22. For example, the control unit 20 identifies the equipment E3 and the time interval 50 corresponding to the specified operation timeline 5 based on the image coordinates (H, V) input by the pointer 41 on the analysis screen illustrated in FIG. 7(A).

[0067] The control unit 20 narrows down the timelines 5 and 6 to be displayed on the post-filtering analysis screen based on, for example, the input information (S12). For example, the control unit 20 excludes from the display targets the operation timelines 5 related to equipment E other than equipment E3 specified in the operation to specify the operation timeline 5.

[0068] In this example, a case will be described in which the narrowing condition for the stay timeline 6 is that the worker W was present in the corresponding work area R during the specified time period 50. In this case, the control unit 20 excludes from the display target any stay timeline 6 in which the specified time period 50 is entirely an absent period 62 (FIG. 6) and does not include a stay period 61 (S12). Note that the stay timeline 6 for the work area R3 of the specified equipment E3 may be included in the display target regardless of the narrowing condition as described above.

[0069] In this example, a case will be described in which the condition for the display order of the stay timeline 6 is the order of the number of times the worker W traveled between the work area R3 corresponding to the specified facility E3 and another work area R. For example, the control unit 20 counts the number of times the worker W traveled between the work area R3 corresponding to the specified facility E3 and another work area R (S13) based on the flow line data D1 for a predetermined period, such as one day. The method for counting the number of times the worker W traveled will be described later.

[0070] The control unit 20 determines the order in which each of the timelines 5, 6 to be displayed is displayed on the post-filtering analysis screen (FIG. 7(B)) based on, for example, the counted number of visits (S4). For example, the control unit 20 determines the operation timeline 5 of the specified facility E3 to be the highest in the display order, sets the stay timeline 6 of the work area R3 of the specified facility E3 to be the next in the display order, and assigns the subsequent display orders to each of the remaining stay timelines 6 to be displayed. At this time, according to the display order conditions described above in this example, the control unit 20 assigns a higher display order to the corresponding stay timeline 6 as the number of visits to the work area R increases.

[0071] Based on the results of the above processing, the control unit 20 controls the display unit 23 to display the narrowed-down timelines 5 and 6 to be displayed in the determined display order on the post-filtering analysis screen, for example, as shown in Fig. 7(B) (S5). As a result, the control unit 20 completes the processing of step S4 in Fig. 8 and proceeds to step S5.

[0072] According to the above-described timeline filtering process (S4), analysis using the timelines 5 and 6 can be made more efficient by limiting the timelines 5 and 6 to be displayed and controlling the display order.

[0073] For example, when a user 15 analyzes a specific time period 50, such as a specific error stop period 52 in a specific piece of equipment E3, as a bottleneck in the workplace 10 (FIGS. 6 and 7), the user 15 may want to check the status of a work area R where a worker W was present during that time period 50. Among these work areas R, a work area R where the worker W frequently traveled to and from the equipment E3 being analyzed is expected to be highly relevant to the bottleneck being analyzed. In such a case, by filtering the timeline using the narrowing down and display order conditions described above (FIG. 10), the user 15 can display a stay timeline 6 that is limited to only those display targets that are useful for bottleneck analysis, enabling the user 15 to efficiently conduct analysis.

[0074] 2-3-2. Number of trips The method for counting the number of trips in this system 1 will be described with reference to FIGS.

[0075] 11 illustrates the positions of various flow lines L1, L2, and L3 in map information D2. Flow line L1 includes position coordinates contained in work areas R1 and R3, in that order. Flow lines L2 and L3 include position coordinates contained in work areas R1, R3, and R4, in that order, respectively. The period during which flow line L2 stays in work area R3 is relatively long, while the period during which flow line L3 stays in work area R3 is relatively short.

[0076] 12 illustrates traffic information D4 in the information analysis device 2. The traffic information D4 manages the first and second work areas in association with the number of visits. The number of visits is the number of times that a worker W moves from the first work area to the second work area, or from the second work area to the first work area. The number of visits based on the flow line data D1 for a predetermined period indicates the frequency with which the worker W moves between the first and second work areas during that period.

[0077] 10, the control unit 20 of the information analysis device 2 increments the number of times traveled between work areas R1 and R3 by one based on the position information of the data for the flow line ID corresponding to flow line L1 in the flow line data D1. Furthermore, based on the data for flow line L2, the control unit 20 increments the number of times traveled between work areas R1 and R3 by one, and increments the number of times traveled between work areas R3 and R4 by one.

[0078] In the example of FIG. 11, the flow line L3 illustrates a case where a worker W passes through work area R3 while traveling between work areas R1 and R4. In such a case, it is considered possible to detect the worker W's stay in the intermediate work area R3 from the data of the flow line L3. For example, the control unit 20 detects that the stay in the intermediate work area R3 is shorter than a preset threshold based on the data of the flow line L3, and increments the number of times the worker W travels between work areas R1 and R4 by one. By counting the number of times the worker W travels, traffic information D4 such as that illustrated in FIG. 12 is obtained. The traffic information D4 is stored, for example, in the memory unit 21 of the information analysis device 2.

[0079] In step S13 of Fig. 10, only the number of visits to work area R3 of specified equipment E3 may be selectively counted. Furthermore, the time when the above-mentioned number of visits is counted is not limited to step S13, but may be, for example, at the time of step S1 in Fig. 8. Furthermore, the entity that executes the counting of the number of visits is not limited to the information analysis device 2, but may also be, for example, the path management server 12. In this case, the control unit 20 can acquire the path information D4 from the path management server 12 instead of step S13, and perform the processes from step S14 onwards.

[0080] 3. Summary As described above, in this embodiment, the information analysis device 2 displays information about a worker W, which is an example of a moving object, in multiple work areas R, which are an example of multiple regions corresponding to multiple pieces of equipment E. The information analysis device 2 includes a display unit 23, an operation unit 22, which is an example of an input unit, a control unit 20, and a storage unit 21. The display unit 23 displays information. The operation unit 22 inputs a user operation. The control unit 20 controls the display unit 23 based on the user operation input via the operation unit 22. The storage unit 21 stores an operation timeline 5, which is an example of operation information indicating the operation state of each piece of equipment E among the multiple pieces of equipment E, and a stay timeline 6, which is an example of detection information indicating the detection results of a moving object in each piece of equipment E among the multiple regions. The control unit 20 accepts a designation operation for the operation timeline 5 via the operation unit 22, as an example of an operation for designating information about a specific piece of equipment E in the operation information of the multiple pieces of equipment E (S3). Based on the information about the equipment E specified in the operation information operation, the control unit 20 limits the information to be displayed on the display unit 23 in the operation information of the multiple equipment E and the detection information of the multiple areas (S4).

[0081] According to the information analysis device 2 described above, the information displayed on the display unit 23 in the operation information of the multiple pieces of equipment E and the detection information of the multiple areas is limited in accordance with the information related to the equipment E specified in the operation information operation, making it easier for the user 15 to analyze the information displayed related to the multiple pieces of equipment E and the moving object. Such display limitations make it easier for the user 15 to visually recognize information for analysis and handling, thereby reducing the various analysis loads on the information analysis device 2.

[0082] In this embodiment, multiple operation timelines 5, which are an example of operation information for multiple pieces of equipment E, include various time intervals during which each piece of equipment E was in a predetermined state (see FIG. 6 ). Information about equipment E specified in the operation information manipulation indicates a time interval 50 during which the equipment E was in a predetermined state. In the timeline filtering process (S4), the control unit 20 includes the detection results of moving objects in the time interval 50 specified in the operation of the operation information in the detection information that is restricted and displayed on the display unit 23, as shown in FIG. 7(B), for example. This allows the user 15 to check the detection results of moving objects in each area in the specified time interval 50 with the display restricted, making it easier to perform the desired information analysis.

[0083] In this embodiment, the control unit 20 may limit the information to be displayed on the display unit 23 in the stay timeline 6 of a plurality of work areas R, which is detection information of a plurality of areas, based on the detection result of a moving object in each area during a specified time period 50 (S12). For example, the display target may be narrowed down to the stay timeline 6 of the work area R where the worker W stayed during the time period 50, thereby reducing the amount of information to be analyzed.

[0084] In this embodiment, the control unit 20 may limit the information to be displayed on the display unit 23 based on the number of traffics, which is the frequency of a moving object moving between an area corresponding to the specified facility E and other areas in the detection information for multiple areas (S14). For example, the memory unit 21 may store flow line data D1 indicating the flow line of the moving object, and the control unit 20 may calculate the frequency of the moving object moving between the area corresponding to the specified facility E and other areas based on the flow line information (S13). By limiting the display in this way, focusing on the movement of moving objects, the analysis load can be reduced.

[0085] In this embodiment, the control unit 20 may limit the detection information to be displayed on the display unit 23 by both narrowing down the detection information to be displayed from the detection information of multiple regions and controlling the display order of the detection information to be displayed (S12, S13). The display restriction of the detection information is not limited to this, and only one of narrowing down the detection information or controlling the display order may be performed.

[0086] In this embodiment, the control unit 20 may limit the operation information to be displayed on the display unit 23 by excluding information about facilities E other than the designated facility E among the plurality of facilities E from the operation information to be displayed on the display unit 23 (S12). This reduces the amount of information to be analyzed, thereby reducing the analysis load.

[0087] In this embodiment, the control unit 20 receives, via the operation unit 22, a designation operation for the stay timeline 6, which is an example of an operation for designating detection information of a specific area in the detection information displayed on the display unit 23 (S5). In response to this operation on the detection information, the control unit 20 causes the display unit 23 to display, as an example of predetermined information related to the detection results of the specified area, an image of the video data D0 in which the specified area was captured (S6). The information analysis device 2 of this embodiment makes it easy to find the detection information to be checked before checking the predetermined information such as this image. The predetermined information is not limited to the above-mentioned image, and can be set to various information related to the detection information of the moving object.

[0088] In this embodiment, the operation information is a stay timeline 6, which is an example of a first timeline that chronologically shows the operating state of the corresponding facility E. The detection information is a stay timeline 5, which is an example of a second timeline that chronologically shows the detection results of a moving object in the corresponding area. These various timelines 5, 6 make it easier to analyze the information displayed regarding each facility E and moving object along a chronological order.

[0089] In this embodiment, there is provided an information analysis method for displaying information about moving objects in multiple areas corresponding to multiple facilities E by a computer. In this method, operation information indicating the operating state of each facility E in the multiple facilities E, and detection information indicating the detection results of moving objects in each area in the multiple areas are stored in the memory unit 21 of the computer. The control unit 20 of the computer accepts, via the operation unit 22, an operation to specify information about a specific facility E in the operation information of the multiple facilities E (S3), and limits the information to be displayed on the display unit 23 in the operation information of the multiple facilities E and the detection information of the multiple areas based on the information about the facility E specified in the operation information operation (S4).

[0090] In this embodiment, a program for causing a computer to execute the information analysis method described above is provided. This method and program make it easier for a user to analyze information displayed regarding the multiple facilities E and the moving object.

[0091] (Embodiment 2) 13 to 17, a second embodiment of the present disclosure will be described below. In the first embodiment, an example of filtering conditions for the timelines 5 and 6 was described. In this embodiment, an information analysis device 2 that can use filtering conditions from various perspectives will be described. Hereinafter, the description of the configuration and operation similar to those of the movement line analysis system 1 and the information analysis device 2 according to the first embodiment will be omitted as appropriate, and only the information analysis device 2 according to this embodiment will be described.

[0092] 13 and 14 illustrate setting menus 44 and 45 in the information analysis device 2 according to embodiment 2. The information analysis device 2 according to this embodiment has the same configuration as that of embodiment 1, but is configured to allow selection of filtering conditions and display order conditions for the stay timeline 6.

[0093] 13 and 14, a menu 44 for setting refinement conditions and a menu 45 for setting display order conditions are provided as pull-down menus on the analysis screens of timelines 5 and 6. The setting menu 44 shown in Fig. 13 includes options for refinement conditions such as "stay," "absence," "traffic," and "area of ​​responsibility." The setting menu 45 shown in Fig. 14 includes options for display order conditions such as "number of visits," "duration of stay," "duration of absence," "distance," and "maintenance."

[0094] 13 and 14, the user 15 can select desired narrowing conditions and display order conditions by operating the menus 44 and 45. After selecting each condition, the user 15 can perform filtering of the timelines 5 and 6 in the same manner as in the first embodiment by performing a designation operation for the operation timeline 5 (S3 in FIG. 8).

[0095] 15 is a flowchart illustrating a timeline filtering process performed by the information analyzing device 2 of embodiment 2. In the same timeline filtering process (S4 in FIG. 8) as in embodiment 1, the information analyzing device 2 of this embodiment narrows down the stay timeline 6 and determines the display order (S12A, S14A) in accordance with the selected conditions, instead of steps S12 to S14 in FIG. 10. In this embodiment, counting the number of visits (S13 in FIG. 10) may be performed in steps S12A and S13A depending on various conditions, or may be omitted as appropriate.

[0096] When "stay" is selected as the narrowing-down condition (see FIG. 13), the control unit 20 narrows down the display targets to the stay timeline 6 of the work area R where the worker W stayed during the time period 50 specified by the specification operation on the operation timeline 5, as in the first embodiment (S12A).

[0097] On the other hand, when the narrowing-down condition “not present” is selected, the control unit 20, in contrast to the above, narrows down the search to the stay timeline 6 of the work area R where the worker W is not present (i.e., not present) during the specified time period 50 (S12A). For example, the narrowing-down condition “not present” is useful for the user 15 currently performing analysis who wants to check the work area R where the worker W is not present.

[0098] Also, when the narrowing down condition “traffic” is selected, the control unit 20 narrows down the display targets to the stay timeline 6 of the work area R where the number of times of traffic to and from the work area R3 of the specified equipment E3 is greater than or equal to a predetermined number (for example, once) based on the traffic information D4 (S12A).

[0099] Furthermore, when the narrowing-down condition "area in charge" is selected, the control unit 20 narrows down the stay timelines 6 to be displayed, for example, by referring to the charge information D5 stored in advance in the storage unit 21 (S12A). An example of the charge information D5 is shown in FIG. 16.

[0100] The responsibility information D5 illustrated in FIG. 16 is an example of management information that records, in association with each other, a "worker" that identifies each individual worker W and a "responsible area" that indicates the work area R that the worker W is responsible for. In the example of FIG. 16, worker W1 is responsible for multiple work areas R1 and R2. In this way, when each worker W is responsible for multiple work areas R, the narrowing condition "responsible area" narrows the stay timeline 6 to be displayed to the work area R that is the same as the work area R3 of the specified equipment E3 and that the same worker W is responsible for (S12A).

[0101] Furthermore, if "number of visits" is selected as a condition for the display order, the control unit 20 sets the display order of the corresponding stay timeline 6 higher, as in the first embodiment, the higher the number of visits to the work area R (S14A).

[0102] When the display order condition "stay duration" is selected, the control unit 20 sets the display order of the corresponding stay timeline 6 higher, for example, the longer the stay duration in the work area R within the specified time section 50 (S14A).

[0103] When the display order condition "absence period" is selected, the control unit 20 sets the display order of the corresponding stay timeline 6 higher, for example, the longer the absence period in the work area R within the specified time period 50 (S14A).

[0104] When the display order condition "distance" is selected, the control unit 20 sets the display order of the corresponding stay timeline 6 higher, for example, the closer the distance between the work area R3 of the specified facility E3 and the work area R (S14A). For example, the control unit 20 refers to the map information D2 and calculates the distance between the work area R3 of the specified facility E3 and the work area R of each facility E. Such a distance is an example of the positional relationship between the work area R3 of the specified facility E3 and the work area R.

[0105] When the display order condition "maintenance" is selected, the control unit 20 sets the stay timeline 6 of the work area R corresponding to the equipment E that has the highest frequency of visits by the workers in charge of maintenance of the equipment E to the top of the display order (S14A). The frequency of visits by maintenance personnel will be described with reference to FIG. 17.

[0106] 17 illustrates map information D2 in this embodiment. The map information D2 in this example includes a waiting area Ra for maintenance personnel for facilities E1 to E4. The frequency of arrival of the maintenance personnel can be calculated as the number of times the maintenance personnel travel between the waiting area Ra and the work area R of each facility E. The control unit 20 calculates the frequency of arrival of the maintenance personnel for the specified facility E3 based on, for example, the map information D2 and the flow line data D1, and sets the display order (S14A).

[0107] As described above, the information analysis device 2 of this embodiment can filter the timelines 5 and 6 using various narrowing conditions and display order conditions, making it easier for the user 15 to analyze the timelines 5 and 6.

[0108] As described above, in the information analysis device 2 of this embodiment, the control unit 20 may limit the information to be displayed on the display unit 23 based on the frequency with which the mobile object travels between the waiting area Ra, which is an example of a predetermined area separate from the multiple areas corresponding to the multiple facilities E, and each of the multiple areas (S14A). This makes it possible to limit the display of the stay timeline 6, taking into account the frequency with which maintenance personnel arrive, for example.

[0109] Furthermore, in the information analysis device 2 of this embodiment, the storage unit 21 may store responsibility information D5, which is an example of management information for managing mobile bodies responsible for each of the multiple areas. The control unit 20 may limit the information to be displayed on the display unit 23 in the detection information for the multiple areas by referring to the management information in response to an operation of the operation information (S13A). This allows the display of the stay timeline 6 to be limited, for example, taking into consideration the overlap of work areas R that are handled by worker W.

[0110] Furthermore, in the information analysis device 2 of this embodiment, the storage unit 21 may store map information D2 indicating the positional relationship between multiple facilities E and multiple areas. The control unit 20 may limit the information to be displayed on the display unit 23 in the detection information for the multiple areas based on the positional relationship between the facilities E specified in the map information and the multiple areas (S14A). This allows the display of the stay timeline 6 to be limited, for example, taking into account the distance between the facilities E.

[0111] In the above explanation, the conditions for narrowing down the stay timeline 6 and the display order have been exemplified, but the information analysis device 2 of this embodiment is not limited to this. For example, the frequency of visits by maintenance personnel and the distance between facilities E may be used as narrowing down conditions, not limited to the display order conditions. Furthermore, the person in charge information D5 may be used as a display order condition. Furthermore, the above various conditions may be applied not only to the stay timeline 6 but also to the operation timeline 5.

[0112] (Other embodiments) As described above, embodiments 1 and 2 have been described as examples of the technology disclosed in this application. However, the technology in this disclosure is not limited to these and can be applied to embodiments in which appropriate modifications, substitutions, additions, omissions, etc. are made. Furthermore, it is also possible to combine the components described in each of the above embodiments to create a new embodiment. Therefore, other embodiments will be described below as examples.

[0113] In the above embodiments, an example of the analysis screen of the information analysis device 2 has been described, but the analysis screen of the information analysis device 2 is not particularly limited to this. For example, in this embodiment, the analysis screen of the information analysis device 2 may not be provided with a scroll bar 40, and may not accept slide operations. For example, the analysis screen of this embodiment may be in a format in which pages transition from top to bottom.

[0114] In the above-described embodiments, an example of filtering has been described in which, when a time interval 50 such as an error stop interval 52 ( FIG. 6 ) of a specific piece of equipment E3 is specified by a user operation, the operation timeline 5 of the other piece of equipment E is excluded from the display target. The information analysis device 2 of this embodiment is not limited to the above, and may display the operation timeline 5 of the other piece of equipment E including the operation timeline 5 of the other piece of equipment E in the filtering results. For example, when a time interval 50 of a specific piece of equipment E3 is specified, the control unit 20 of the information analysis device 2 may extract an operation timeline 5 having an error stop interval 52 that is temporally continuous with the specified time interval 50 from the operation timeline 5 of the other piece of equipment E, and include it in the display target. This makes it easier to analyze the status of the piece of equipment E in which consecutive errors have occurred when an error or the like has occurred in the specific piece of equipment E3.

[0115] In each of the above embodiments, an example has been described in which the information analysis device 2 generates the stay timeline 6 based on the flow line data D1, but the information analysis device 2 of this embodiment is not limited to this. In this embodiment, the stay timeline 6 may be generated not only from the flow line data D1 but also from the video data D0 of the work area R. Furthermore, the stay timeline 6 may be generated not only by the information analysis device 2 but also by the flow line management server 12.

[0116] In each of the above embodiments, the stay timeline 6 has been described as an example of the detection information. In this embodiment, the detection information is not limited to the stay timeline 6, and may include, for example, the number of workers W who stayed in the corresponding work area R, or individual identification.

[0117] In the above embodiments, examples have been described in which each work area R is set within the imaging range of a separate camera 11, but the present system 1 is not particularly limited to this. In the present embodiment, multiple work areas R may be included in the imaging range of one camera 11, or one work area R may span the imaging ranges of multiple cameras 11. For example, in response to a designation operation on the stay timeline 6, the information analysis device 2 may display video data including imaging results of at least a portion of the corresponding work area R. Furthermore, the correspondence between equipment E and work area R is not necessarily one-to-one; for example, multiple work areas R may correspond to one equipment E, or one work area R may correspond to multiple equipment E.

[0118] In each of the above embodiments, the worker W has been described as an example of a moving object. In this embodiment, the moving object may be a person other than the worker W, or may be a living thing, various vehicles, or robots, etc., without being limited to a person.

[0119] As described above, the embodiments have been described as examples of the technology in the present disclosure, and for that purpose, the accompanying drawings and detailed description have been provided.

[0120] Therefore, the components shown in the accompanying drawings and detailed description may include not only essential components for solving the problem, but also components that are not essential for solving the problem in order to illustrate the above technology. Therefore, the fact that these non-essential components are shown in the accompanying drawings or detailed description should not be interpreted as immediately indicating that these non-essential components are essential.

[0121] Furthermore, since the above-described embodiments are intended to illustrate the technology of the present disclosure, various modifications, substitutions, additions, omissions, etc. may be made within the scope of the claims or their equivalents. [Industrial Applicability]
