<Embodiment 1>
FIG. 1 is a block diagram showing the configuration of a work management device according to the first embodiment. As shown in FIG. 1, the work management device 100 includes a work instruction information acquisition section 110, an output section 120, a management section 130, a recording section 140, and a determination section 150. Work management device 100 is connected to network 300 (not shown). Network 300 may be wired or wireless. The network 300 is, for example, a LAN (Local Area Network), Bluetooth (registered trademark), Wi-Fi (registered trademark), or the like. A work tool 200 (not shown) is connected to the network 300.

The work management device 100 is, for example, an information processing device such as a personal computer, a smartphone, or a tablet terminal. The work instruction information acquisition unit 110 acquires work instruction information written in general-purpose software. The output unit 120 outputs the work instruction information acquired by the work instruction information acquisition unit 110 as at least one of visual information and audio. The management unit 130 manages the work contents of the work tool 200. The recording unit 140 records the working time required to perform the outputted work. The determination unit 150 determines whether the work content managed by the management unit 130 and the work time recorded by the recording unit 140 meet the criteria.

Although details will be described later, the worker performs work using the work tool 200 based on work instruction information output from the output unit 120. For example, when the work management device 100 is a personal computer, the output unit 120 is a monitor and a speaker of the personal computer. Moreover, the output unit 120 may be a wearable device that can communicate with the personal computer. Wearable devices include, for example, earphones and smart glasses. If the output unit 120 is a wearable device, the worker can receive the work instruction information even if he or she is away from the work management device 100, so there is no need to approach the work management device 100 to receive the work instruction information. Therefore, the worker does not have to leave the work site every time he receives work instruction information, and can proceed with the work efficiently.

The work instruction information is information regarding the work content that the worker performs using the work tool 200. Specifically, the work instruction information includes the work order when a worker performs multiple tasks, the type of work tool 200 used for each work, the threshold value (setting threshold value) of the work tool 200 set for each work, and This includes the number of workers involved in each task. The work tool 200 is a tool used by a worker when performing work. The work tool 200 can communicate with the work management device 100 via the network 300. The work tool 200 is, for example, an IoT (Internet of Things) tool such as a digital torque wrench.

The general-purpose software is not particularly limited as long as it is software that can input work instruction information and does not require programming expertise when editing. The general-purpose software includes, for example, text editing software such as Notepad (registered trademark), spreadsheet software such as Excel (registered trademark), and the like. Hereinafter, a general-purpose software file in which work instruction information is written may be referred to as a "work instruction information file." For example, when changing work instructions, a worker, manager, or the like edits the work instruction information file. The work instruction information file can be edited on general-purpose software. In other words, even a person without programming expertise can edit the work instruction information file. In this way, since the operation and maintenance of the work instruction information file is easy, the work management device 100 has high maintainability.

Next, an example of the operation of the work management device 100 will be described with reference to FIG. 2. FIG. 2 is a flowchart showing the flow of a work management method (work management method according to the first embodiment) performed using the work management device 100. First, the work instruction information acquisition unit 110 acquires work instruction information written in general-purpose software (step S101).

Next, the output unit 120 outputs the work instruction information acquired by the work instruction information acquisition unit 110 as at least one of visual information and audio (step S102). Visual information is information that can be visually recognized by humans, such as images and animations. The worker selects the work tool 200 based on the work instruction information output from the output unit 120 and performs the work. Upon completion of the work, the work tool 200 transmits the work details to the work management device 100 via the network 300.

The management unit 130 acquires the work content transmitted by the work tool 200 (step S103). Next, the determination unit 150 compares the work content acquired by the management unit 130 and the work instruction information acquired by the work instruction information acquisition unit 110, and determines whether the work content is appropriate (step S104). . If the work content is not appropriate (No in step S104), the output unit 120 notifies the user that the work content is inappropriate as an abnormality (step S105). The worker who has been notified of the abnormality selects the work tool 200 again and performs the work. Upon completion of the work, the work tool 200 transmits the work details to the work management device 100 via the network 300. The management unit 130 again acquires the work details transmitted by the work tool 200 (step S103).

If the work content is appropriate (step S104 Yes), the recording unit 140 records the working time of the work tool 200 (step S106). Next, the determination unit 150 determines whether all the work has been completed (step S107).

If there is any work that has not been completed (No in step S107), the output unit 120 outputs the next work instruction information (step S108). The worker performs the next work using the work tool 200 based on the next work instruction information. When the work is completed, the work tool 200 transmits the next work content to the work management device 100 via the network 300. The management unit 130 acquires the next work content transmitted by the work tool 200 (step S103). In this way, the work management device 100 outputs work instruction information according to the work situation and records the work content and work time until the worker finishes all the work (step S107 Yes).

Note that the work management device 100 includes a processor, a memory, and a storage device as components not shown. Further, the storage device stores a computer program in which the processing of the work management method according to the present embodiment is implemented. Then, the processor loads a computer program from the storage device into the memory and executes the computer program. Thereby, the processor realizes the functions of the work instruction information acquisition section 110, the output section 120, the management section 130, the recording section 140, and the determination section 150.

Further, the work instruction information acquisition section 110, the output section 120, the management section 130, the recording section 140, and the determination section 150 may each be realized by dedicated hardware. Further, a part or all of each component of each device may be realized by a general-purpose or dedicated circuit, a processor, etc., or a combination thereof. These may be configured by a single chip or multiple chips connected via a bus. A part or all of each component of each device may be realized by a combination of the circuits and the like described above and a program. Further, as the processor, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an FPGA (field-programmable gate array), etc. can be used.

Further, in the case where a part or all of each component of the work management device 100 is realized by a plurality of information processing devices, circuits, etc., the plurality of information processing devices, circuits, etc. may be centrally arranged, It may also be distributed. For example, information processing devices, circuits, etc. may be realized as a client server system, a cloud computing system, or the like, in which each is connected via a communication network. Further, the functions of the work management device 100 may be provided in a SaaS (Software as a Service) format.

<Embodiment 2>
Embodiment 2 is a more specific embodiment.

FIG. 3 is a block diagram showing the configuration of a work management system (work management system according to the second embodiment) using the work management device according to the second embodiment. The work management system 400 includes a work management device 100a and a work tool 200, as shown in FIG. Work management device 100a and work tool 200 are connected via network 300. Note that explanations that overlap with those of Embodiment 1 will be omitted as appropriate.

The work management system 400 includes a work management device 100a instead of the work management device 100 shown in FIG. In addition to the configuration shown in FIG. Equipped with. The management section 131 includes a transmitting section 132, a receiving section 133, and a notification section 134.

The transmitter 132 transmits the set threshold value of the power tool 200 to the power tool 200. The receiving unit 133 receives the work content of the work tool 200. The notifying unit 134 notifies when the work content received by the receiving unit 133 is less than the set threshold of the working tool 200.

The work history storage unit 160 stores the work history of each work. The work history includes work content and work time. The work history output unit 170 outputs the work history stored in the work history storage unit 160. The input unit 180 is an input means to the work management device 100a. The worker performs operations such as selecting a work to be performed and outputting a work history from the input unit 180. For example, when the work management device 100a is a personal computer, the input unit 180 is a keyboard of the personal computer. If the input unit 180 is a device such as a keyboard that the worker can operate with his or her fingers, the worker can perform input operations on the work management device 100a even in a noisy environment.

The input unit 180 may be an audio input device such as a microphone. When the input unit 180 is a voice input device, the input voice is subjected to voice recognition and natural language processing in a voice recognition engine such as Julius (registered trademark). If the input unit 180 is a voice input device, the worker can perform an input operation on the work management device 100a even in a situation where he cannot use his hands, such as when he is carrying luggage in both hands. Further, the input section 180 may be an input/output section integrated with the output section 120. The input/output unit is, for example, an intercommunication system (intercom).

The work instruction information storage unit 190 stores work instruction information. As shown in FIG. 3, the work instruction information storage unit 190 stores a work instruction information file 191 containing work instruction information. The work instruction information is information for instructing the worker on the work to be performed by the worker. In the second embodiment, a worker uses a work tool 200 to perform work. A worker usually performs multiple tasks. When there are multiple tasks to be performed by a worker, the work instruction information includes information on the order in which each task is performed, that is, work order information. Hereinafter, each work performed by a worker based on work instruction information may be referred to as an element work. Further, the k-th element work performed in a series of element works may be referred to as the k-th work. Note that k is a natural number from 1 to n, and n is the total number of elemental tasks included in the work instruction information.

As shown in FIG. 3, the k-th work instruction information includes, for example, the work tool ID of the work tool 200 used in the k-th work, the set threshold value of the work tool 200, the number of workers in the k-th work, and the k-th work instruction information. This includes the estimated working hours, etc. The work tool ID of the work tool 200 is an ID for distinguishing each work tool 200. For example, when the work tool 200 is a digital torque wrench, the set threshold value of the work tool 200 is the target torque value set in the k-th work.

Although only one work instruction information file 191 is shown in FIG. 3, the work instruction information storage unit 190 normally stores work instruction information files 191 regarding a plurality of different tasks. That is, the work instruction information storage unit 190 stores work instruction information regarding a plurality of different tasks.

Next, an example of the operation of the work management device according to the second embodiment will be described with reference to FIGS. 4 and 5. FIG. 4 is a flowchart showing the flow of a work management method (work management method according to the second embodiment) performed using the work management device 100a. FIG. 5 is a flowchart showing the flow of the k-th work.

First, the worker selects a task to be performed from among the tasks whose task instruction information is stored in the task instruction information storage section 190 (step S201). Note that the work instruction information file 191 is normally saved in the work instruction information storage section 190 in advance prior to step S201. When a work to be performed is selected (step S201), the work instruction information acquisition unit 110 reads the work instruction information of the relevant work stored in the work instruction information storage unit 190 (step S202).

Next, k is set to 1 (step S203), and the k-th work instruction is executed (step S204). That is, the first work instruction is given. Next, the determining unit 150 determines whether k is equal to n (step S205). If k is not equal to n (No in step S205), the k-th work instruction is executed with k+1 as k (step S204). For example, when n is 3 and the first work instruction is executed with k as 1 (step S204), k is not equal to n (step S205 No), so step S204 is performed with 2 as k.

If k is equal to n in step S205 (step S205 Yes), that is, if all the elemental tasks have been performed, the output of the work instruction information is ended. Next, the worker checks the work history stored in the work history storage unit 160 (step S207), and outputs the work history (step S208). The data format of the work history output in step S208 is not particularly limited, and may be, for example, a csv (Comma Separated Values) file, an Excel (registered trademark) file, a PDF (registered trademark) file, or the like.

As described above, in the work management method according to the second embodiment, it is possible to instruct the worker to perform all the elemental works included in the work instruction information in a predetermined order and output the work history data. can. Therefore, even if the work involves many elemental works or the work is unfamiliar to the worker, there is no need to appoint a work leader or refer to a manual, etc., so the work can be done efficiently. Furthermore, if the work content in each elemental work does not meet the standards, that is, if an abnormality occurs in each elemental work, an instruction to proceed to the next elemental work is not output, so that work errors can be suppressed. Furthermore, since the work management device 100a records the work history, there is no need to secure personnel to write the work history or to record it by the worker himself. In other words, the necessary records for tracking work history can be automatically left. In addition, in the work management method according to the second embodiment, since the working time of each elemental work is recorded, it is possible to know which elemental work the worker is spending time on, that is, which elemental work is the bottleneck work. can be understood and analyzed.

Next, execution of the k-th work instruction (step S204) will be described in detail with reference to FIG. In the example shown in FIG. 5, a case will be described in which the k-th work is a work of tightening a bolt using a digital torque wrench as the power tool 200.

As shown in FIG. 5, first, the output unit 120 outputs the k-th work instruction information (step S301). Next, the transmitter 132 transmits the target torque value as a set threshold to the power tool 200 used in the k-th work (step S302). The recording unit 140 starts measuring the working time, with the time when the output unit 120 outputs the k-th work instruction information as the start time (step S303).

The worker selects the work tool 200 based on the k-th work instruction information output from the output unit 120 and executes the work. The power tool 200 issues an alarm indicating completion of tightening when the torque value approaches the received set threshold. The operator determines that the bolt tightening is completed based on the alarm, and transmits the tool communication ID and torque value of the work tool 200 to the work management device 100a. The tool communication ID and torque value of the work tool 200 are transmitted, for example, by the operator operating a button provided on the work tool 200.

The receiving unit 133 acquires the tool communication ID and torque value of the work tool 200 by receiving them (step S304). Next, the determination unit 150 determines whether the work tool 200 used by the worker is the correct tool (step S305). In step S305, the determination unit 150 compares the tool communication ID acquired by the reception unit 133 with the work tool ID included in the k-th work instruction information in the work instruction information file 191, and determines that the ID is correct if they match. It is determined that it was a tool. If the work tool 200 used by the worker is not the correct tool (No in step S305), the notification unit 134 notifies the worker that the wrong work tool 200 is being used (step S306).

If the work tool 200 used by the worker is the correct tool (step S305 Yes), it is determined whether the torque value during work satisfies the standard (step S307). In step S307, if the torque value acquired by the receiving unit 133 is within the standard of the set threshold included in the k-th work instruction information in the work instruction information file 191, the determination unit 150 determines that the torque value at the time of work is the standard. It is determined that the following is satisfied. If the torque value during work does not meet the criteria (No in step S307), the notification unit 134 notifies the worker that the torque value does not meet the criteria (step S308).

The notification in step S306 and step S308 is performed, for example, via the output unit 120. When at least one of step S306 and step S308 is performed, that is, when at least one of the fact that the work tool 200 is incorrect and the torque value does not meet the standard is notified, the worker selects the work tool 200 again and performs the work. I do. Then, the work tool 200 transmits the tool communication ID and the torque value to the work management device 100a when the work is completed. In this manner, in the work management method according to the second embodiment, steps S304 to S308 are repeatedly performed until the work is performed using the correct work tool 200 and with a torque value within the standard. If the torque value during the work satisfies the criteria (Step S307 Yes), the recording unit 140 writes the torque value in the work history storage unit 160 as the work content for the k-th work (Step S309).

Next, the determining unit 150 determines whether the number of workers is satisfied (step S310). The number of workers is the number of locations where the work performed in the k-th work is performed. For example, in the example shown in FIG. 5, the number of workers is the number of bolts tightened in the k-th task. In step S310, the determination unit 150 determines whether the number of torque values recorded as the work content in the work history storage unit 160 is the number of tightened bolts, and whether the number matches the number of workers. If the number of workers does not match (No in step 310), the worker uses the work tool 200 to tighten the bolts that have not been completely tightened. If the numbers of workers do not match (No in step 310), the notification unit 134 may notify the workers that there are bolts that have not been tightened yet.

If the number of workers matches (Step S310 Yes), the determination unit 150 determines that the k-th work has been completed, and the recording unit 140 records the work time with the end time at which the k-th work is completed. The measurement is ended (step S311). The determination unit 150 determines whether the measured work time is within the standard of the expected work time included in the k-th work instruction information in the work instruction information file 191 (step S312). If the working time does not meet the standard for the expected working time (step S312 No), the notification unit 134 notifies the worker that the working time is inappropriate (step S313). Next, the recording unit 140 writes the measured work time into the work history storage unit 160 (step S314).

In this manner, in the work management method according to the second embodiment, the work management device 100a does not determine that the k-th work has been completed until the number of workers matches, so that forgetting and omitting work can be suppressed. In other words, the work management device 100a has a pokayoke function.

<Other embodiments, etc.>
In the embodiment described above, a case has been described in which the worker sequentially executes the elemental tasks according to instructions from the work management device 100a, but the worker himself may select the task to be performed within each elemental task. For example, in the example shown in FIG. 5, when the output unit 120 outputs the k-th work instruction (step S301), a plurality of tasks may be presented to the worker, and the worker may select the task to be performed. In this case, the work management device 100a executes each step from step S302 to step S314 according to the work selected by the worker. Further, in the embodiment described above, a case has been described in which one work tool 200 is communicably connected to the work management device 100, but two or more work tools 200 may be connected.

Further, in the above-described embodiment, the case where the worker performs the elemental work using the work tool 200 has been described, but the series of elemental works may include elemental work performed without using the work tool 200. . The element work performed without using the work tool 200 is, for example, work in which a worker visually checks a member and records the check result. In this case, the transmitter 132 does not perform step S302, and the worker performs the work based on the outputted k-th work instruction information, and then records the work details in the work management device 100a. For example, the worker operates the input unit 180 to record the work details. The determination unit 150 compares the recorded work content with the work content included in the k-th work instruction information in the work instruction information file 191, and if they match, the correct work has been performed, and the k-th It is determined that the work has been completed.

In addition, although the above-mentioned embodiment was explained as a hardware configuration, it is not limited to this. The present disclosure can also realize arbitrary processing by causing the CPU to execute a computer program.

In the examples above, the program may be stored and provided to the computer using various types of non-transitory computer readable media. Non-transitory computer-readable media includes various types of tangible storage media. Examples of non-transitory computer-readable media include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, Includes CD-R/W, DVD (Digital Versatile Disc), and semiconductor memory (for example, mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, and RAM (Random Access Memory)). The program may also be provided to the computer on various types of transitory computer readable media. Examples of transitory computer-readable media include electrical signals, optical signals, and electromagnetic waves.
