Nihon Keizai Shimbun Press Release, "Hitachi Industry & Control Solutions Launches Status Collection / Visualization System" VSIP "for Manufacturing / Logistics Sites", [online], 2017/6/14, [Search on September 11, 2018], Internet <URL: https://www.nikkei.com/article/DGXLRSP448019_U7A610C1000000/>

In each of the prior arts such as Patent Document 1, Patent Document 2, and Non-Patent Document 1 described above, the recorded image of the camera is only displayed in an easy-to-understand manner in a virtual three-dimensional space or the like, and the work of the worker is performed correctly. It was not enough for the administrator to understand that.
In addition, in order to cover a wide range of work sites, a large number of surveillance cameras constantly photograph each area. Therefore, the captured video data is large, and it takes a lot of labor for the administrator to narrow down from the large amount of video data whether or not the specific work content by the specific worker is correctly executed.

For example, when a problem with a certain product is pointed out from the outside, consider the case of tracking whether the pre-shipment inspection of the product was performed correctly. The administrator can prove the authenticity of the work log by finding the video data of the corresponding inspection work from a large amount of video data. However, visually confirming the corresponding video data is too burdensome for the administrator.

Therefore, the main object of the present invention is to have the manager efficiently confirm the work contents of the worker from the photographed data in which the work of the worker is recorded.

In order to solve the above problems, the work management system of the present invention has the following features.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an external view of a work site to which a work management system is applied.
At the work site, a worker possessing the worker terminal 2 is performing work such as assembling the product 101 and inspecting the member 102. In order to monitor the work status of workers, a beacon 3 and a bird's-eye view camera 4 are installed in each predetermined range (area) of the work site at the upper part (overhead view point) of the work site.
The bird's-eye view camera 4 is configured as a camera capable of shooting in all directions (360 degrees), for example, and constantly creates image data of a work site. As the shooting performance of the bird's-eye view camera 4, it is desirable that the image data having a bird's-eye view of the factory has a resolution that allows the worker to be visually recognized even if the image data is enlarged.
The beacon 3 is installed on a wall surface or the like in a factory, and constantly transmits radio waves indicating its own position information to the surroundings by Bluetooth (registered trademark) or the like. By controlling the output of the radio wave, each beacon 3 causes the worker terminal 2 that receives the radio wave to specify its own area.

The worker terminal 2 has the following means.
(1) A position detection means that receives a radio wave from the beacon 3 and obtains the current position of the worker terminal 2. With this position detection means, it is possible to make the manager confirm that the worker is proceeding with the work at an appropriate place.
(2) A qualification authentication means for authenticating whether or not the user of the worker terminal 2 is a worker who has the qualification to work.
(3) A work support means for making a worker grasp the contents of the work to be performed on the display screen and accepting the work result from the input screen.

FIG. 2 is a plan view of the work site of FIG.
A combination of the beacon 3 and the bird's-eye view camera 4 is installed in each of the areas 71 to 79. That is, the position information transmitted by the beacon 3 installed in the same area and the position information of the image data recorded by the bird's-eye view camera 4 can be associated with each other as the same position information. Since the position information of the beacon 3 and the position information of the bird's-eye camera 4 may be associated with each other, the number of beacons 3 and the number of bird's-eye cameras 4 may be 1: 1 or one bird's-eye view camera 4. A plurality of beacons 3 may be installed within the shooting range of.

As components of the work management system, FIG. 2 further shows a premises LAN 91, a wireless router 92 connected to the premises LAN 91, a relay device 93, and a work management server 1. The administrator uses the work management server 1 to confirm the work performed by the worker.
Since the image data from the bird's-eye view camera 4 has a large amount of data, wired communication is desirable when transferring the image data to the work management server 1 via the relay device 93. When the position information obtained from the beacon 3 is transferred from the worker terminal 2 to the work management server 1, since the amount of data is small, wireless communication may be performed via the wireless router 92 or wired communication may be used.

The work management server 1 is configured as a computer having a CPU (Central Processing Unit), a memory, a storage means (storage unit) such as a hard disk, and a network interface.
In this computer, the CPU operates a control unit (control means) composed of each processing unit by executing a program (also referred to as an application or an abbreviation thereof) read in the memory.

FIG. 3 is a functional block diagram of the work management system.
The work management system includes a work management server 1, a worker terminal 2, a beacon 3, a bird's-eye view camera 4, and a qualification management server 6.
The qualification management server (worker authentication server) 6 registers in advance authentication information about a worker who has a qualification to work as a user of the worker terminal 2. The authentication information is, for example, face image information, finger vein information, iris information, password information, and the like.
When the worker performs an operation such as logging in to the worker terminal 2 to be grasped, the worker is prompted to input the authentication information by the qualification authentication means of the worker terminal 2. Then, the qualification management server 6 receives the authentication information input from the worker according to a protocol such as LDAP (Lightweight Directory Access Protocol).
The qualification management server 6 collates the authentication information received this time with the authentication information registered in advance to determine the identity of the worker (who logged in) and the qualification of the worker (up to what level). Do you allow the work of) and authenticate.

The work management server 1 has a work confirmation unit 10, an image storage DB 11, a work item master (work item database) 12, a work record DB 13, a work-related DB 14, and a storage processing unit 15. The work management server 1 may be divided into separate devices as a search processing device having a work confirmation unit 10 and a storage processing device having a storage processing unit 15.
Further, in FIG. 3, various DBs (image storage DB 11, work item master 12, work record DB 13, and work-related DB 14) are provided inside the work management server 1, and each processing unit (work confirmation unit 10, work confirmation unit 10) in the same device is provided. It is configured to be accessed from the storage processing unit 15). On the other hand, various DBs (image storage DB 11 and the like) of the work management server 1 are housed in a device (network storage device) different from the work management server 1 and accessed from each processing unit of the work management server 1 via the network. May be good.

The storage processing unit 15 stores the tagged image data in which the photographed image data received from the bird's-eye view camera 4 and the worker position data received from the worker terminal 2 are associated with each other in the image storage DB 11. In the work result DB 13, the work result created by the work support means of the worker terminal 2 is accumulated as the work result.
A list of work items to be performed in the future is pre-registered in the work item master 12. Detailed information about work items and workers is pre-registered in the work-related DB 14 by the administrator.

When the work item registered in the work item master 12 and the work result registered in the work record DB 13 match each other, it can be considered that the work has been performed without any problem. On the other hand, five items of work A, B, C, D, and E are registered in the work item master 12, but only three items of work results A, B, and D are registered in the work record DB 13. There may be discrepancies. At that time, the administrator can view the progress status (completed or incomplete) registered in the work record DB 13 via the display screen of the work confirmation unit 10 for each work registered in the work item master 12. Leakage of C and E can be confirmed.

The work confirmation unit 10 causes the administrator to confirm the specific work contents performed by the worker based on various DBs (image storage DB 11, work item master 12, work record DB 13, and work-related DB 14). For example, the work confirmation unit 10 displays the captured image data of the image storage DB 11 on the screen to determine which product the worker is working on by using an appropriate tool or mechanism. You can check the details such as whether it is.

FIG. 4 is a configuration diagram of the image storage DB 11.
In the image storage DB 11, when the number of beacons 3 and the number of bird's-eye cameras 4 are 1: 1, the image data shooting date and time, the image data shooting position (area No.), the image data, and the image data are displayed. It is associated with the overlay character information attached as a tag.
For example, the first line shows the image data taken at 10:10 on August 1, 2018 in the area "1" where the worker A is located. As described above, since the beacon 3 installed in the same area and the bird's-eye view camera 4 are associated with each other, the storage processing unit 15 has an image from the bird's-eye view camera 4 created at the same time and at the same place, respectively. The data and the worker position data from the beacon 3 can be associated with each other. In FIGS. 4 to 7, the column that is the primary key is emphasized by hatching, such as "date and time, area No." of the image storage DB 11.

FIG. 5 is a configuration diagram of the work item master 12. The work item master 12 is composed of a work item first table 12a and a work item second table 12b.
In the work item first table 12a, the work item name, the target device, and the area NO in which the target device exists are associated with each other as the work content specified for each work identification number. That is, the work indicated by the work item name is only the work for the target device, not the work for the area NO. For example, in the first line, the work of performing a periodic inspection of the device A existing in the area "1" is registered as the "1" number. In addition, only one target device may exist in one area, or a plurality of target devices may exist.

In the work item 2nd table 12b, as the details of the work contents specified for each work identification No. of the work item 1st table 12a, the procedure contents for each work procedure No. and the workers who may perform the procedure contents may be performed. Correspond to the qualification of. That is, for one work identification number, one or more work procedure numbers are registered in the work item second table 12b.
For example, in the first line, as the details of the periodic inspection of the device A, the work of the level 1 worker checking the angle of XX and the work of the level 2 worker checking the value of XX are arranged in order. It is registered to do.

FIG. 6 is a configuration diagram of the work record DB 13.
In the work record DB 13, the work identification No., the work procedure No., the date and time when the work was actually performed, the ID of the worker who performed the work, the work (inspection) result, and the place where the work was performed ( The actual area NO.) Is associated with the remarks related to the work. That is, 0 or more work results [date and time, worker ID, inspection result, actual area No., remarks] are associated with one set of [work identification NO., Work procedure NO.]. The 0 set of work results indicates a state in which the scheduled work has not been executed, and the 2 sets of work results indicate a state in which the scheduled work has been executed in duplicate.
For example, in the first row of the work record DB 13, the work scheduled as the first row of the work item second table 12b is performed on August 1, 2018 in the area "1" by the worker with the worker ID = 1. It is executed at 10:10, and the result is shown to be "good".
In this way, every time the work support means of the worker terminal 2 receives the work result from the worker, the work result is notified from the worker terminal 2 to the work management server 1, and the notification content is newly added to the work record DB 13. Added as a record.

FIG. 7 is a block diagram of the work-related DB 14. The work-related DB 14 is composed of a work-related first table 14a and a work-related second table 14b.
The work-related first table 14a is a table in which detailed information of the worker is registered. In the work-related first table 14a, the worker ID, the worker name, and the qualification possessed by the worker are associated with each other.
The work-related second table 14b is a table in which detailed information of the area where the work is performed is registered. In the work-related second table 14b, the area No. and the area name are associated with each other.

FIG. 8 is a sequence diagram showing work by a worker and work confirmation by an administrator.
First, the work preparatory processing (S111, S101) will be described.
The work management server 1 accepts registration of work contents from the administrator (S111). The administrator inputs the data of the work item master 12 that can be input before the work is performed and the data of the work-related DB 14 to the work management server 1.
The worker terminal 2 authenticates the worker to be operated by various authentication functions (camera image face authentication, button press fingerprint authentication, etc.) provided in the tablet terminal and the Web application authentication function (password authentication, etc.). (S101). As described above, the worker terminal 2 performs authentication in cooperation with the qualification management server 6.

Hereinafter, S102 to S104 are processes during work.
The behavior of the worker in the work area is tracked and recorded by the following image capturing process and position acquisition process (S102).
The image shooting process is a process of adding a shooting position and a shooting time as tags to the image data shot by the bird's-eye view camera 4. The position acquisition process is a process of adding the current date and time and the worker ID to the data indicating the current position of the worker (where the worker is in) detected by the worker terminal 2 that received the radio wave from the beacon 3. Is.

The storage processing unit 15 of the work management server 1 records the image data obtained in the image shooting process and the data indicating the current position of the worker obtained in the position acquisition process in the image storage DB 11 in association with each other. S112). As a result, the position data, the time data, the image data, and the worker ID are prepared. Therefore, in the subsequent input of the search parameter of the administrator (S114), the corresponding image data can be specified by specifying the combination of the position data and the time data. And the worker ID can be taken out from the image storage DB 11. That is, each data recorded in the image storage DB 11 in S112 can be utilized as work tracking data by the worker.

Then, the worker grasps the confirmation screen showing the work contents of the work item master 12 via the worker terminal 2 to execute the work, and inputs the work result to the worker terminal 2 on the screen. The work result will be described later in FIG. 9, and is, for example, an inspection result showing whether or not the fitting angle of the cylinder is appropriate. The worker terminal 2 notifies the work management server 1 of the input work result as a work result (S103).
The work management server 1 associates the notified work record with the work identification No. and the work procedure No. of the work item master 12 shown on the confirmation screen, and registers them in the work record DB 13 shown in FIG. 6 ( S113). Workers continue to work in the same area or in different areas. Therefore, the process of S102 and the process of S103 are repeatedly executed when the next work of the worker exists (S104, Yes).
The image shooting process of S102, the position acquisition process of S102, and the work execution process of S103 operate in parallel with each other and are always operating.

Hereinafter, S114 to S115 are post-work processes.
The work confirmation unit 10 of the work management server 1 accepts input of a search parameter for narrowing down a desired work from the work history by the worker from the administrator (S114). A basic example of a search parameter specifies a combination of position data and time data. By this designation, it is confirmed whether or not the worker was actually working in the correct area and at the correct time. As for the search parameters, various input methods are prepared in order to correspond to various viewpoints for narrowing down the work (details will be described later in FIGS. 10 and 11).

The work confirmation unit 10 of the work management server 1 searches each DB (image storage DB 11, work item master 12, work record DB 13, work-related DB 14) for records matching the search parameters in S114, and the administrator searches the search results. It is displayed on the confirmation screen to be viewed by (S115).
For example, when the search parameter of S114 is a combination of position data and time data, by displaying the record of the image storage DB 11 that matches the combination, the photographed image of the worker is browsed and the work that matches the combination is displayed. By displaying the record of the achievement DB 13, the worker's work achievement is confirmed.

Further, the work confirmation unit 10 uses the combination of the work identification NO. Read from the record of the work record DB 13 of the search result and the work procedure No. as a new search key, and also combines the records of the matching work item master 12. It may be displayed on the confirmation screen.
In this way, by displaying the corresponding record of the work item master 12 and the corresponding record of the work record DB 13 together on the confirmation screen, the administrator can easily check whether or not the work content to be executed is correctly executed. Can be collated. That is, the corresponding record in the work record DB 13 allows the administrator to confirm that the time when the work was executed is correct and that the work was executed in compliance with the work content specified in the work item master 12.

FIG. 9 is a display screen view of the worker terminal 2. This display screen is displayed toward the worker in S112 of FIG.
On the display screen, a work outline table 111, a work input table 112, a pass button 113, a defect button 114, and a correction button 115 are displayed. Further, the worker terminal 2 is also provided with an in-camera 116.
As the work outline table 111, detailed information of the work contents read from the work item master 12 is displayed. The detailed information is composed of, for example, a work number, a product number, a product name, a process, a worker ID, and a work area. This allows the worker to confirm the work to be performed.

The work input table 112 is an input field for work results performed by the worker. As the work result, a check indicating that the work has been performed, a work item indicating the classification of the work content, the work content, and the work result are associated with each other.
The worker inputs the work result by using the pass button 113, the defect button 114, and the correction button 115, or by using the text box in the work result column or the pull-down menu.
Further, the worker terminal 2 authenticates the worker to be operated in advance (S101 in FIG. 8). At the time of this authentication, the face of the worker is photographed by the in-camera 116 and collated with the face authentication information in the qualification management server 6.

In the present embodiment described above, the work management system acquires the work record, which is the record of the work based on the work instruction of the work item master 12, from the work record DB 13 and causes the administrator to confirm it, and also takes a picture from the image storage DB 11. Have the manager visually confirm the actual work situation and worker behavior by using images.
As a result, the work record of the worker, the video including the worker ID corresponding to the work record, and the position information of the worker when the work is performed can be confirmed in association with each other, so that the administrator can check the worker. Knowing that the work was done correctly, the authenticity of the work log is proved.

Therefore, as a preparation for the administrator to confirm, a large amount of recorded data of the entire factory is stored in the image storage DB 11 and the work record DB 13. In order to allow the administrator to efficiently search for the work content to be focused on from the large amount of data, the storage processing unit 15 has the position data, the time data, and the work in the image at the stage of recording the image data in the image storage DB 11. The member's ID data is added as a search tag.
Based on this tag, the work confirmation unit 10 can efficiently search for the work content that the administrator pays attention to. That is, in order to search across the work contents by combining (matching) the work record data of the work record DB 13 and the captured image data of the image storage DB 11, the information of the position data and the time data is stored in both databases. It has been recorded.
