The present invention relates to a production performance recording system and a production performance recording program.

At production sites, equipment operating hours are recorded as a means of understanding production results. However, in reality, setup work by the operator also occurs. For this reason, if only the operating hours of the equipment are used, the actual production results will be recorded as less than the actual amount.

Examples of conventional techniques include the following techniques.

In Patent Document 1, status information indicating the relationship between the status of the equipment and the status of the worker is generated based on equipment information indicating the status of the equipment and worker information indicating the status of the worker.

Furthermore, in Patent Document 2, workers in a production site are photographed, and operating results are determined and recorded from patterns presented by the workers.

International Publication 2017/198652 Japanese Patent Application Publication No. 2014-174653

However, in the technique disclosed in Patent Document 1, only the operating hours of equipment are recorded for the purpose of budget and actual management as product production results. For this reason, in the technique of Patent Document 1, the setup work performed by workers while the equipment is not in operation is not recorded as production results. In the technique of Patent Document 2, although the worker is photographed, the operation results are merely recorded based on the pattern presented by the photographed worker. For this reason, even in the technique of Patent Document 2, the setup work performed by workers while the equipment is not in operation is not recorded as production results.

The present invention has been made in view of the above circumstances, and an object of the present invention is to be able to record the operation status of the equipment as well as the setup work by the worker as production results in production using equipment.

Furthermore, the dimensional ratios in the drawings are exaggerated for convenience of explanation and may differ from the actual ratios.

FIG. 1 is an explanatory diagram for explaining the functional configuration of a production record recording system according to an embodiment.

The production record recording system 1 includes a server 10, a camera 20 connected to the server 10, and a terminal 18 connected to the server 10.

The server 10 has a production plan acquisition section 11, a production start/end recording section 12, an equipment operation record recording section 13, a video recording section 14, a work record recording section 15, and a linking section 17 as its functions.

The server 10 is a computer and includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), an HDD (Hard Disk Drive), an interface (IF) for external connection, and the like. The server 10 also includes input devices such as a keyboard and mouse, and output devices such as a display.

In the server 10, each function is realized by the CPU reading and executing a program stored in a storage device such as a ROM or an HDD.

Furthermore, in the server 10, in addition to the HDD, a nonvolatile storage medium such as an SSD (Solid State Drive) or a nonvolatile storage device may be used as the storage device.

Additionally, the server 10 is provided with an interface. The interface communicates with equipment 50, camera 20, and terminal 18. Examples of the interface include various local connection interfaces such as network interfaces based on standards such as Ethernet (registered trademark), SATA, PCI Express, USB, and IEEE 1394, and wireless communication interfaces such as Bluetooth (registered trademark) and IEEE 802.11. Further, the interface may be a line for making a local analog connection with the equipment 50 and the camera 20. Further, the interface may be a wireless LAN (WiFi) or a mobile phone line in order to connect with the terminal 18.

A terminal 18 connected to the server 10 is a computer. The terminal 18 is, for example, a personal computer (PC), a tablet, a smartphone, or the like. These are computers used by workers, managers, and other parties. These computers have input devices such as a keyboard, mouse, and touch panel, and output devices such as a display. The terminal 18 is used to input a production plan (details will be described later). The terminal 18 is also used to display production results (details will be described later). A plurality of terminals 18 may be connected to one server 10. When a plurality of terminals 18 are connected to one server 10, input of production plans, display of production results, etc. are performed from each terminal 18. Further, input devices and output devices connected to the server 10 may be used for inputting production plans, displaying production results, and the like. In this case, the terminal 18 may not be provided.

The functions of each part of the server 10 will be explained.

The production plan acquisition unit 11 acquires a production plan for products produced by the equipment 50. The production plan is input from the terminal 18 to the production plan acquisition section 11 . The production plan acquisition unit 11 records the input production plan in a storage device within the server 10. In this embodiment, production refers to various production activities using the equipment 50, such as product processing, molding, and parts attachment.

FIG. 2 is an explanatory diagram for explaining an example of a production plan file. FIG. 3 is an explanatory diagram for explaining an input screen for inputting a production plan.

Production planning data is often provided, for example, in an electronic file such as a CSV (Comma Separated Values) format or a TSV (Tab Separated Values) format as shown in FIG. Note that an electronic file is data that can be used on a computer.

However, the contents of the production plan file differ depending on the person who ordered the product to be produced and the production plan planner (collectively referred to as a production plan provider). For example, various items such as product number, equipment used, production quantity, and scheduled shipping date may be arranged differently in each file, and some items may or may not be present in each file. For this reason, conventionally, when inputting a production plan, it was necessary to rearrange the files received from the production plan provider so that they were in the same format.

The production plan acquisition unit 11 provides an input screen for associating the provided production plan file with items used in the production performance recording system 1. On the input screen, for example, as shown in FIG. 3, a plurality of checkboxes 110 are arranged vertically, and checkbox windows 111 to 115, which group the plurality of checkboxes 110, are arranged horizontally.

To input a production plan, first, a production plan file is selected from the input screen. The selected production plan file is displayed in the file selection window 101 in the input screen. The selected production plan file is uploaded to the server 10 by pressing the upload button 102. The uploaded file is stored in a storage device within the server 10.

Next, the check box 110 is checked according to the contents of the input production plan file. After the check box 110 is checked, the save button 103 is pressed to finalize the checked contents. Note that the button being pressed includes instructions such as a touch with a finger or a pen when the display screen is a touch sensor, and a mouse click when the display screen is a pointer (the same applies hereinafter).

When the save button 103 is pressed, the production plan acquisition unit 11 links the checked item and each item of the CSV file. For example, linking is performed so that the horizontal order of the check box windows 111 to 115 is the same as the order of the items in the CSV file. Specifically, for example, the first checkbox window 111 of the checkbox 110 is linked to the first item of the CSV file. The second checkbox window 112 of the checkbox 110 links to the second item in the CSV file. The same goes for the third and subsequent ones. If the check box 110 for "manufacturing number" in the first check box window 111 of the check box 110 is checked, the first item of the CSV file is linked as "manufacturing number". Linking is the same for the second and subsequent items. Furthermore, if there is no check box 110 corresponding to the content of the item in the CSV file, it may be left unchecked.

As a result, in this embodiment, the provided production plan file can be taken in as it is without being changed and used for recording production results.

Note that the production plan file is not limited to being input or uploaded from the terminal 18; for example, it may be stored in another computer and called up from there. Furthermore, the production plan file is not limited to a CSV format file. The production plan file may be in various file formats, such as Microsoft's Excel file format and XML format.

In this embodiment, for example, the product number (serial number) for identifying the product to be produced, the scheduled production time for each product, the equipment number if the equipment 50 used for production is specified, etc. If a person is specified, the specified worker etc. will be acquired. Therefore, it is preferable that check boxes 110 corresponding to these exist on the input screen. Of course, the items of the acquired production plan are not limited to these.

The production start/end recording unit 12 receives inputs for starting, suspending, restarting, and ending work from a worker terminal 31 operated by a worker 30, for example. The production start/end recording unit 12 provides the worker terminal 31 with an input screen for inputting information such as temporary stop, restart, and end.

The worker terminal 31 is a computer. As the worker terminal 31, for example, a mobile terminal such as a tablet or a smartphone is preferable. By carrying these with the worker 30, the worker 30 can input the start and end of production wherever he or she is. The connection between the server 10 and the worker terminal 31 (mobile terminal) is preferably made by wireless communication, and for example, a wireless LAN (WiFi), a mobile phone line, or the like is used.

When the worker terminal 31 is a mobile terminal, an identification number (ID) is stored in each mobile terminal. It is preferable that the ID of the mobile terminal is linked to the worker 30.

The worker terminal 31 is not limited to a mobile terminal. As the worker terminal 31, for example, a personal computer (PC) arranged for each process or for each piece of equipment 50, a control panel or an operation panel of the equipment 50, etc. can be used.

The input screen is provided using part of the production plan data acquired by the production plan acquisition unit 11 so that the worker 30 can understand the products and equipment 50 to be produced. The input screen also includes buttons for inputting start, pause, restart, and end of work by the worker 30. The buttons displayed on the input screen are buttons and icons displayed on the display using a graphical interface.

FIG. 4 is an explanatory diagram for explaining an example of an input screen for inputting a start. As shown in FIG. 4, on the input screen for inputting the start, there is a product number button 201 that displays the number of the product scheduled to be produced, and an equipment button that displays information about the equipment 50 that will produce the product. 202 is displayed. By pressing the product number button 201 and the equipment button 202, the product number of the product to be produced and the equipment 50 to be used are selected. In FIG. 4, the button frames of selected buttons are shown by solid lines, and the button frames of unselected buttons are shown by broken lines (the same applies to other figures).

On the start input screen, a start button 203 for inputting the start of production is displayed. After the product number and equipment 50 are selected (input) by the worker 30, the start button 203 is pressed to input the start of production.

When the start of production is input, the production start/end recording unit 12 records the production start time in the storage device. The production start time is recorded as the time when the product with the selected product number started being produced by the selected equipment.

When the start of production is input from a mobile terminal, the production start/end recording unit 12 identifies and records the worker 30 from the input ID of the mobile terminal.

Once the start is input, the production start/end recording unit 12 provides the worker terminal 31 with an input screen for inputting pause and end.

FIG. 5A is an explanatory diagram for explaining an example of an input screen for inputting pause and termination. FIG. 5B is an explanatory diagram for explaining an example of an input screen for inputting restart and termination.

The input screen shown in FIG. 5A displays product number information for identifying the product currently in production and information on the equipment 50 currently producing the product. On the input screen shown in FIG. 5A, a pause button 301 and an end button 302 for inputting temporary stop and end of production are displayed.

When the worker 30 presses the pause button 301, a pause in production is input. When a temporary stop of production is input, the production start/end recording unit 12 records the temporary stop time in the storage device. The temporary stop time is recorded as the time when the product with the displayed product number was temporarily stopped during production by the displayed equipment.

When the pause button 301 is pressed, the production start/end recording unit 12 provides a screen change from the pause button 301 to a resume button 303. As a result, the pause button is changed to a resume button 303, as shown in FIG. 5B.

When the worker 30 presses the restart button 303, restarting production is input. The production start/end recording unit 12 records the time in the storage device when a restart of production is input. The restart time is recorded as the time when production of the product with the displayed product number was resumed by the displayed equipment.

The end of production is input by the worker 30 pressing the end button 302 . The production start/end recording unit 12 records the time in the storage device when the end of production is input. The end time is recorded as the time when production of the product with the displayed product number by the displayed equipment ended.

Note that the resume button may not be provided. For example, if there is no need to take temporary suspension into account as production results, there is no need to provide a restart button.

The equipment operation record recording unit 13 records the operating status of the equipment 50, such as operation or non-operation, as an operation record. The operation record of the equipment 50 is, for example, operation due to normal operation for production, stoppage after production is completed, abnormal stoppage when an abnormality occurs, and stoppage when the equipment 50 is not used.

The equipment operation record recording unit 13 acquires the operation record of the equipment 50 by, for example, detecting the emission color of the laminated signal light 51 installed in the equipment 50 or detecting a switching signal. When detecting the emitted light color or switching signal, a dedicated sensor (not shown) for detecting them is used. The equipment operation performance recording unit 13 (server 10) is connected to a sensor that detects the color of emitted light and the switching signal.

The laminated signal light 51 is also called a three-color laminated light, a signal tower, etc., and most of them have three color lamps of green, yellow, and red that emit light according to the operating performance of the equipment 50. The laminated signal light 51 normally turns green during normal operation, yellow when stopped due to production completion, and red when an abnormality occurs.

Further, if a signal indicating the operation performance is output from the equipment 50, the equipment operation record recording unit 13 may acquire the signal. In this case, the equipment operation record recording unit 13 (server 10) is connected to the equipment 50.

Further, the equipment operation record recording unit 13 may acquire the operation record from the video data of the camera 20. In this case, the laminated signal light 51 is placed in the photographing area of the camera 20. The equipment operation record recording unit 13 detects the emitted light color of the laminated signal light 51 from the video data.

The video recording unit 14 records video data from the camera 20. The equipment operation record recording unit 13 is, for example, a storage device within the server 10. Video data is recorded over time. As the camera 20, a general movie camera can be used.

The work record recording section 15 acquires video data from the video recording section 14 . The work record recording unit 15 determines the number of workers 30 present in the predetermined area and the time period during which the workers 30 existed in the predetermined area from the video data. The work record recording unit 15 stores the determined number of workers 30 and the time the workers 30 existed in the storage device. As the time during which the worker 30 was present, the time from when the presence of the worker 30 was confirmed in the predetermined area to when it was no longer confirmed is stored.

FIG. 6 is an explanatory diagram for explaining a predetermined area in which the presence of the worker 30 is determined. As shown in FIG. 6, the predetermined area for determining the presence of the worker 30 is set within the photographing area 25 of the camera 20. The camera 20 is installed so that a range including at least the equipment 50 is a photographing area 25. In addition, as already explained, when detecting the operation record of the equipment 50 from video data, the camera 20 is installed so that the laminated signal light 51 is included in the imaging area 25.

In this embodiment, as shown in FIG. 6, two areas, a first area 41 and a second area 42, are set as the predetermined areas. The first area 41 and the second area 42 are set exclusively.

The first area 41 is an area where the operator 30 can directly work on the equipment 50 or the products set in the equipment 50. The first area 41 is, for example, a range within which the operator 30 can reach the equipment 50 and the set products. For example, the distance of the first region 41 as indicated by the arrow a in FIG. 6 is about 1 m.

The second area 42 is next to the equipment 50. The second area 42 is, for example, a range where setup work necessary for product production is performed. In the second region 42, for example, the distance indicated by arrow b in FIG. 6 is about 1 to 2 m.

In this embodiment, two areas are set as the predetermined areas, but the invention is not limited to this. The predetermined area may be one area or three or more areas. Further, the setting position is also arbitrary. However, it is preferable to set at least one range in which the operator 30 works on the equipment 50 or the product as the predetermined area. When one predetermined area is set, the predetermined area and the photographing area 25 may be in the same range.

The worker 30 can be detected from the video data using, for example, a background subtraction method. As is well known, in the background subtraction method, a background image is registered and the background image is compared with a frame of video data that changes from moment to moment to check for differences. The work record recording unit 15 determines that the worker 30 is present if there is a different part within the predetermined area by comparing the background image and each frame.

However, in order to confirm the presence of the worker 30, if the object detected by the background subtraction method is smaller than the worker 30, it will not be recognized as the worker 30. Furthermore, in the present embodiment, if there are multiple objects equivalent to the worker 30 in each area, or if an object larger than the worker 30 is detected, it is assumed that a plurality of workers 30 exist. If the objects equivalent to the workers 30 are recognized separately, the work record recording unit 15 records that there are the same number of workers 30. If the size of the detected object is the size of a plurality of workers 30 combined, the work record recording unit 15 records that the number of workers 30 is present. For example, if the size of the detected object is about the size of one worker, the work record recording unit 15 records that one worker 30 is present. Furthermore, if the size of the object is about the size of two workers, the work record recording unit 15 records that two workers 30 are present. In this case, the number of workers 30 is recognized by comparing the size of the workers 30 stored in advance in the storage device with the size of the object detected by the background subtraction method. The size of the worker 30 should be close to that of a human to some extent.

Alternatively, for example, skeleton recognition technology can be used to detect the worker 30 from the video data. Skeleton recognition technology includes, for example, Open Pose (see https://github.com/CMU-Perceptual-Computing-Lab/openpose etc.), Deep Pose (https://www.slideshare.net /mitmul/deeppose-human-pose-estimation-via-deep-neural-networks etc.)).

Skeleton recognition technology recognizes the human skeleton from two-dimensional video data. Therefore, the skeleton recognition technology can recognize each worker 30 individually.

In skeletal recognition technology, a person in a video is identified using three-dimensional coordinate values. The three-dimensional coordinate system and coordinate origin to be used are set in advance. Further, coordinate values indicating the ranges of the first region 41 and the second region 42 are also set in advance in the three-dimensional coordinate system. The work performance recording unit 15 compares the coordinate values of the worker 30 detected by the skeleton recognition technology with the coordinate values indicating the ranges of the first area 41 and the second area 42, and determines whether the worker 30 is present in each area. Determine whether or not to do so and record it. At the same time, the work record recording unit 15 records the number of workers 30 detected by the skeleton recognition technology, if a plurality of workers 30 are detected.

Note that the video recording unit 14 may cooperate with the work record recording unit 15 so as not to record video data while the presence of the worker 30 is not recognized. In this case, the camera 20 photographs and acquires video data, and the video data is recorded in the storage device only while the work record recording unit 15 recognizes the presence of the worker 30 from the video data. Alternatively, a human sensor may be provided separately, and the camera 20 may take a picture only when a person is detected within the photographing area 25. In this case, video data is recorded in the storage device only while the person is being sensed. Of course, all video data may be recorded in the storage device regardless of the presence or absence of the worker 30.

The linking unit 17 links each information from the production plan acquisition unit 11, the production start/end recording unit 12, the equipment operation record recording unit 13, and the work record recording unit 15 to the video data. The information includes production plan information from the production plan acquisition unit 11, production start and end information from the production start/end recording unit 12, equipment operation performance information from the equipment operation performance record unit 13, and work performance records. This is information on work results from department 15.

More specifically, the production plan information is, for example, information acquired from the production plan file, as already explained.

The information on the start and end of production is, for example, the time when the worker 30 inputs the start of production and the time when the end of production is input.

The equipment operation record information is, for example, the time when each state of lights out, operation (green), stop (yellow), and abnormality (red) was switched.

The information on the work performance is the number of workers and the time of presence in a predetermined area. For example, for each of the first area 41 and the second area 42, the number of workers and the presence from the time when the presence of the worker 30 was confirmed are determined. This is the time when it can no longer be confirmed.

The linking unit 17 links each piece of information and video data based on time.

FIG. 7 is a time chart in which each piece of information linked by the linking unit 17 is displayed.

In the time chart shown in FIG. 7, the equipment 50 is the equipment operation record, and corresponds to the color of the laminated signal light 51.

In the time chart shown in FIG. 7, the worker item is work performance, and indicates whether or not a worker 30 is present in a predetermined area and the number of workers 30 present. As for the predetermined regions, the first region 41 is "front" and the second region 42 is "lateral". Although the number of workers 30 is shown by different hatching of the bars, it is preferable to show it by different colors in the actual screen display. For example, the number of workers 30 is one worker when the bar is green, two workers when the bar is yellow, and three or more workers when the bar is red. In the time chart shown in FIG. 7, production corresponds to start, pause, restart, and end of production.

In the time chart shown in FIG. 7, the production results correspond to the start of production and the end of production.

In the time chart, this information is arranged in chronological order.

The time chart is output from the linking unit 17 in response to a request from the terminal 18.

Various things can be understood from the time chart of FIG.

Production of product number [37557] started at 08:00 and ended at 08:35. In other words, it can be seen that product number [37557] was produced in 35 minutes. During this time, the equipment 50 is in operation from 08:06 to 08:26. Further, the worker 30 exists in the predetermined area even before the equipment 50 starts operating, and the worker 30 exists for a long time. Conversely, after the equipment 50 is operated, the worker 30 remains in the predetermined area for a short time.

It can be seen that in section A immediately before the end of production of product number [37557], the equipment 50 is stopped and there is no worker 30 in the predetermined area. In such a section A, for example, it is estimated that there is a possibility that a signal indicating the end of production has not been inputted from the worker 30 even though production has actually ended.

After the production of product number [37557] ends, production of product number [37558] will start. It can be seen that there was an abnormal stop of equipment in section B during production of product number [37558]. In addition, it can be seen that in section B, production was restarted after being temporarily stopped based on input from the worker 30. Outside section B, the production of product number [37558] is the same as the previous production.

After the work for product number [37558] is completed, production for product number [50021] will begin. Even if production of product number [50021] has started, the equipment 50 is not in operation within the range shown in the time chart. However, the worker 30 is present in the predetermined area. This is presumably due to the fact that, for example, the production requires different jigs and programs from the products that were previously produced, so it takes time to change setups.

In this manner, in this embodiment, each piece of information on the production results is displayed as a time chart, so that the manager and other workers 30 can easily confirm the results of the production results.

The equipment operation results, work results, and production results (production start and production end) are linked with the video data by the linking unit 17. Therefore, in FIG. 7, each bar of the equipment 50, the worker 30, the production results, and the time (time) of each bar are linked to the video data by the linking unit 17. Therefore, by pressing each bar on the time chart in FIG. 7, video data in the time range of each bar is read out from the video recording unit 14 and played back.

FIG. 8 is an explanatory diagram for explaining reading of video from the time chart. For example, when a certain bar in the displayed time chart is pressed from the terminal 18, the start time of that bar is transmitted to the linking unit 17. Here, it is assumed that the part indicated by the broken line circle in the time chart shown in FIG. 8 is pressed. The linking unit 17 reads the video data from the video recording unit 14 using the received time as a key, and outputs it to the terminal 18. In the terminal 18, for example, as shown in FIG. 8, the received video data is displayed as a video (video) 400 on the same screen as the time chart. Note that the video may be displayed in an enlarged manner so that only the video is displayed on the screen.

Each piece of information and video data linked by the linking unit 17 is linked by time. Therefore, in this embodiment, linked past data can be read.

In this way, in this embodiment, the video data can be checked as needed from the time chart displayed as the result of the production results. You can check the status on video and confirm the cause of the delay.

FIG. 9 is an explanatory diagram for explaining an example of reading past data. As shown in FIG. 9, when reading past data, a calendar 405 is first displayed on the screen. A date and time to be read from calendar 405 is specified. A time chart 406 of the designated date and time is displayed on the same screen as the calendar 405.

These displays are output from the linking unit 17 to the terminal 18 in response to a request for past data from the terminal 18.

Each piece of information linked by the linking unit 17 can be summarized in a display form other than a time chart. FIG. 10 is an explanatory diagram for explaining an example in which linked pieces of information are compiled into a tabular report.

As shown in FIG. 10, by organizing each piece of information in a table format, various pieces of information representing production results can be obtained as text information. Such a tabular report is output from the linking unit 17 to the terminal 18 in response to a request from the terminal 18. At the terminal 18, this report is used by a manager or the like when comparing plans and actual results.

For example, if there is a difference between the production plan and actual production results, the worker 30 who was in charge of the work at the date and time when the discrepancy between the schedule and actual results occurred is identified. The situation at that time is then confirmed, and the cause of the work delay is identified. Furthermore, the number of workers 30 is displayed, which is used for evaluating personnel allocation. For example, if a plurality of workers 30 are found to be present at a site where one person usually works alone, it is presumed that an irregular situation is occurring.

Note that in the report shown in FIG. 10, the worker 30 is, for example, the worker 30 associated with the ID of the worker terminal 31 (portable terminal) that inputs the start of production. Further, information on the worker 30 may be written in, for example, a production plan file. In this case, the linking unit 17 extracts and uses the information of the worker 30 in the production plan file acquired by the production plan acquisition unit 11.

In addition, the tabular report also includes a temporary stoppage, indicating that there was an interruption in the middle of production.

The processing procedure for recording production results will be explained. FIG. 11 is a flowchart showing the processing procedure for recording production results. The server 10 executes the production record recording program created based on this processing procedure, thereby implementing the functions of each section described above.

First, the server 10 acquires a production plan (S1).

Subsequently, the server 10 determines whether the start of production has been input (S2). Here, if the start of production has not been input (S2: NO), the server 10 advances the process to S8. Processing after S8 includes operation performance recording (S8), video data recording (S9), work performance recording (S10), and the like.

In this way, in this embodiment, even if production start is not input, the processing from S8 onwards is performed, so the status of equipment and workers is recorded regardless of whether production start is input. be able to. As a result, in this embodiment, even if the start of production is not input, the administrator can read the records of the server 10 later and check the operating status of the equipment, the working status of the workers, and the video of the site. You can check.

On the other hand, if the start of production is input in S2 (S2: YES), the server 10 records the time when the start of production was input in the storage device (S3). At this time, the server 10 switches the input screen displayed on the terminal 8 to an input screen for pause and end.

Subsequently, the server 10 determines whether a temporary stop of production has been input (S4). If production suspension has not been input (S4: NO), the server 10 determines whether production termination has been input (S13). Here, if the end of production has not been input (S13: NO), the server 10 advances the process to S8. If the end of production is input (S13: YES), the server 10 stores the time when the end of production was input in the storage device (S14). After that, the server 10 advances the process to S8.

In this way, in this embodiment, the processing from S8 onward is performed regardless of whether or not an input to end production is made. The status of the person can be recorded.

In S4, if the temporary stop of production is input (S4: YES), the server 10 records the time when the temporary stop of production was input in the storage device (S5). At this time, the server 10 switches the input screen displayed on the terminal 8 to the restart and termination input screen.

Subsequently, the server 10 determines whether a restart of production has been input (S6). If restart of production has not been input (S6: NO), the server 10 determines whether termination of production has been input (S13). The processes in S13 and S14 are as already described.

In S6, if the restart of production is input (S6: YES), the server 10 records the time when the restart of production was input in the storage device (S7). At this time, the server 10 switches the input screen displayed on the terminal 8 to an input screen for pause and termination.

Subsequently, the server 10 records equipment operation results (S8).

Subsequently, the server 10 records video data (S9).

Next, the server 10 analyzes the video data, and if the worker 30 is present in the predetermined area, the server 10 records the number of workers and the time of presence as the work performance of the worker 30 (S10).

Subsequently, the server 10 links the obtained information and video data (S11).

Subsequently, if the server 10 receives an input to end the processing (S12: YES), the server 10 ends all processing. On the other hand, if the end of processing is not input (S12: NO), the server 10 returns to S2 and continues the subsequent processing.

Note that in the processing procedure, S9 and S10 are a set, and may be processed before S8.

According to this embodiment described above, the following effects are achieved.

In this embodiment, the operation record of the equipment 50 and whether or not the worker 30 is working on the equipment 50 are recorded. Thereby, this embodiment can accurately record the operating state of the equipment 50 as well as the setup work by the worker 30.

In this embodiment, in addition to the equipment operation time, it is determined whether or not the worker 30 exists in a predetermined area set around the equipment during product production, and if the worker 30 exists, the existence time is recorded. I decided to do so. Accordingly, in this embodiment, it is possible to understand that there is a time when the worker 30 is working around the equipment 50 even when the equipment 50 is not in operation. Furthermore, in this embodiment, the operating time of the equipment 50 and the working time of people can be considered separately, which can be used to accurately calculate labor costs and equipment costs.

Furthermore, in this embodiment, when importing a production plan, it is possible to reduce the work load for correcting it into a prescribed format. As a result, in this embodiment, in addition to reducing the workload, it is possible to easily accommodate a wide variety of formats that differ from business to business. Thereby, in this embodiment, for example, the administrator can devote time to the original management work, which can be used to improve the efficiency of the administrator work.

Furthermore, in this embodiment, information on the start and end of production, information on equipment operation results, information on work results by the worker 30, and English and Japanese data are linked. This allows each piece of information to be displayed in a variety of formats. Therefore, for example, when there is a discrepancy between the production plan and the actual results, the manager can understand the situation at the site at the time of the work delay from time charts, table data, and even videos and images. Furthermore, in the present embodiment, it is possible to understand not only the video data of the worker 30 but also information on the manufacturing work that the worker 30 was undertaking and the equipment 50 that the worker 30 was using in combination in chronological order. Accordingly, in this embodiment, the cause of the bottleneck that caused the delay can be identified. Furthermore, in this embodiment, cause analysis can be performed based on accurate results, so appropriate countermeasures can be taken.

Although the embodiments of the present invention have been described above, various modifications are possible. Although the embodiment has been described as the functions of the server 10, the functions of the server 10 can be implemented by a small computer. For example, a personal computer (PC), board PC, etc. can be used.

Further, as the server 10, a cloud server on the Internet may be used. When using a cloud server, the equipment 50 and the camera 20 are provided with an interface that can be connected to the Internet, and the operational performance of the equipment 50 and the video data of the camera 20 are transmitted to the cloud server. The connection between the equipment 50 and the camera 20 and the Internet may be a wireless connection or a wired connection. When using a cloud server, an existing internet-connectable web camera can be used as the camera 20 by simply attaching an interface for internet connection to the equipment 50, so initial investment can be reduced. In addition, when using a cloud server, if the operation record of the equipment 50 is acquired from the emitted light color of the laminated signal light 51 in the video data, only the installation of a web camera is required, so the initial investment can be further reduced. I can do it.

In addition, if the equipment 50 is equipped with an audible alarm that notifies the equipment 50 that it is in operation or has stopped due to an abnormality, the operating performance of the equipment 50 may be acquired by sound.

Further, the laminated signal lamp 51 is not limited to three colors, and may be applied to a two-color laminated signal lamp 51, a one-color laminated signal lamp 51, or the like. For example, in the case of a two-color laminated signal light 51, green indicates normal operation and red indicates abnormal stop. In this case, the green color indicates the device is in operation, and the red color and off state indicate the device is stopped, so processing can be performed accordingly. Similarly, the same applies in the case of one color, and in the case of using the laminated signal lamp 51 of four colors or five colors.

Furthermore, in the embodiment, the number and presence time of workers in a predetermined area are acquired using video information from the camera 20, but the present invention is not limited to this. The number of workers in a predetermined area and the length of time they exist can be determined by, for example, obtaining location information from workers wearing RFIDs (Radio Frequency Identifiers), and determining the number of workers in a predetermined area from the number of signals from the RFID. You can get the number of Also, by having the worker carry a beacon transmitter, location information and number can be obtained. In addition to the number and presence time of workers in a given area, the location information and number of workers can also be obtained by PDR (Pedestrian Dead Reckoning) using acceleration sensors, angular velocity sensors, magnetic sensors, etc. can.

In addition, the conditions and numerical values used in the description of the embodiments are for illustration purposes only, and the present invention is not limited to these conditions and numerical values.

Further, the present invention can be modified in various ways based on the configuration described in the claims, and these are also within the scope of the present invention.
