1. Example of embodiment 1-1. Example of configuration of work instruction system First, the configuration of a work instruction system according to an example of embodiment (hereinafter, referred to as "this example") will be described with reference to Figs. 1 to 3.
Fig. 1 is a schematic diagram showing an example of the configuration of a work instruction system, and Fig. 2 is an explanatory diagram showing a device held by a worker in the work instruction system.

The work instruction system 1 shown in FIG. 1 is a system that instructs a worker M1 on the work content during elevator installation work, and acquires the work content actually performed by the worker M1. The work instruction system 1 includes an information determination unit 2, a worker information storage unit 3, a work content storage unit 4, an information presentation unit 5, an information collection unit 6, and an information storage unit 7. The work instruction system 1 also includes a device terminal 10 and a voice device 11 owned by the worker M1. The device terminal 10 and the voice device 11 make up the terminal equipment.

As shown in Figures 1 and 2, the device terminal 10 is a mobile information terminal consisting of, for example, a smartphone or a tablet terminal. The device terminal 10 is connected to the information determination unit 2, the information collection unit 6, and the information storage unit 7 so as to be able to transmit and receive information. The device terminal 10 has a display unit 13 and an input unit 14. The display unit 13 displays the contents of the work instructions output from the information determination unit 2. The display unit 13 also displays a manual showing the work procedures output from the information storage unit 7. The device terminal 10 outputs the information input to the input unit 14 to the information determination unit 2 and the information collection unit 6.

The audio device 11 is connected to the device terminal 10. The audio device 11 is, for example, configured from headphones, earphones, bone conduction speakers, etc. The audio device 11 also has a microphone that acquires the voice of the worker M1. The audio device 11 outputs audio information such as work instructions and manuals that the device terminal 10 receives from the information determination unit 2 and the information storage unit 7. The audio device 11 also outputs the voice of the worker M1 acquired by the microphone to the device terminal 10. The audio device 11 may also be provided with an input unit configured from a touch button, a touch sensor, etc.

Various storage devices such as clouds and servers are used as the worker information storage unit 3, work content storage unit 4, information presentation unit 5, information collection unit 6 and information storage unit 7. Various information related to worker M1 is stored in the worker information storage unit 3. Information related to worker M1 (hereinafter simply referred to as "worker information") includes, for example, years of experience, company affiliation, age, gender, disaster history, and professional qualifications. The worker information is stored in the worker information storage unit 3 in association with ID information that identifies worker M1. Examples of ID information include numbers, the fingerprints, face, and voice of worker M1.

The work content memory unit 4 stores multiple work contents A and B for each work process. In addition, the work content memory unit 4 stores multiple work instruction contents A, B, and C that instruct the worker M1 on the work content and procedure for each of the multiple work contents A and B. The work instruction contents A, B, and C are created according to the proficiency of the worker M1 in the corresponding work.

FIG. 3 is an explanatory diagram showing differences in work instructions that are output depending on the level of skill of the worker M1.
The content A of the work instruction shown in Fig. 1 is a work instruction for a highly skilled worker M1. As shown in Fig. 3A, the content A of the work instruction for the highly skilled worker M1 is only output as a voice indicating the work instruction from the audio device 11. Moreover, the action instruction content C shown in Fig. 1 is a work instruction for a less skilled worker M1. As shown in Fig. 3B, the content C of the work instruction for the less skilled worker M1 is not only displayed as an image on the display unit 13 of the device terminal 10, but also output as a voice indicating the work instruction from the audio device 11.

As for the contents of the work instructions, guidance to the manual stored in the information storage unit 7, which will be described later, is displayed on the device terminal 10. If the work instructions output from the device terminal 10 or the audio device 11 are not clear to the worker M1, the worker M1 can view the manual stored in the information storage unit 7 by operating the guidance displayed on the display unit 13 of the device terminal 10.

Although an example has been described in which the contents A, B, and C of multiple work instructions are created based on the proficiency of worker M1, this is not limiting. For example, the contents A, B, and C of multiple work instructions may be created based on the years of experience, professional qualifications, or past disaster history of worker M1.

The information collection unit 6 outputs information about the work actually performed by the worker M1 (work content information) from the device terminal 10. The work content information is created from information about the operation of the device terminal 10 by the worker M1 and from voice information of the worker M1 acquired by the voice device 11. The information collection unit 6 records the work content information.

Examples of the work content information include response time until work completion and manual viewing information. The information collection unit 6 calculates and stores the response time from the time of specific operations performed by the worker M1 on the device terminal 10 or the voice device 11 for each work instruction. Examples of specific operations include input operations on the input unit 14 of the device terminal 10 and specific voice operations made into the microphone of the voice device 11. Examples of the manual viewing information include the content of the manual viewed by the worker M1 while working, the viewing time, and the number of times it was viewed. The work content information stored in the information collection unit 6 is organized, analyzed, and processed by the information determination unit 2.

The information presentation unit 5 stores the work content information organized and analyzed by the information judgment unit 2. Hereinafter, the organized and analyzed work content information will be referred to as processed work content information. The information presentation unit 5 is provided with a display unit and an input unit (not shown). The information presentation unit 5 is configured so that the processed work content information can be viewed by the client who ordered the work and the manager who manages the work (hereinafter referred to as a third party) M2. The processed work content information is information indicating the progress of the work and areas for improvement in the work or the product, etc.

The information storage unit 7 stores manuals showing detailed procedures for each task. The information storage unit 7 is connected to the device terminal 10. When the worker M1 operates the device terminal 10 or the audio device 11, the manuals stored in the information storage unit 7 are displayed on the display unit 13 or output as audio from the audio device 11. Information on the manuals viewed by the worker M1 operating the device terminal 10 or the audio device 11 is recorded in the information collection unit 6.

The information determination unit 2 is connected to the worker information storage unit 3, the work content storage unit 4, the information presentation unit 5, the information collection unit 6, and the device terminal 10 so as to be able to send and receive information. The information determination unit 2 has a CPU (Central Processing Unit), RAM (Random Access Memory), and ROM (Read Only Memory), and is an AI (artificial intelligence) that analyzes and organizes the acquired information.

The information determination unit 2 acquires worker information from the worker information storage unit 3 based on the ID information input to the device terminal 10. The information determination unit 2 calculates the proficiency of worker M1 in each task based on the acquired worker information. The proficiency of worker M1 is calculated based on, for example, years of experience, professional qualifications, and disaster history. The information determination unit 2 also selects work instruction content that matches the proficiency of worker M1 from the task content storage unit 4. The information determination unit 2 then outputs the selected work instruction content to the device terminal 10.

The proficiency of worker M1 in each task may be stored as the worker information stored in the worker information storage unit 3. This reduces the proficiency calculation process by the information determination unit 2. Although an example has been described in which worker information is stored in the worker information storage unit 3 and the task instruction content is stored separately in the task content storage unit 4, this is not limiting. For example, the worker information and the task instruction content may be stored together in a single storage unit.

The information determination unit 2 also collects, organizes, and analyzes the work content information recorded in the information collection unit 6. The information determination unit 2 then organizes and analyzes the work content information recorded in the information collection unit 6 to convert it into, for example, information indicating work progress information and areas of improvement for the work or product (processed work content information). The information determination unit 2 records the processed work content information, which is information indicating the progress of the work and areas of improvement, in the information presentation unit 5.

Note that some or all of the components, functions, processing units, etc. constituting the above-described work instruction system 1 may be realized in hardware, for example, by designing an integrated circuit. Also, the above-described components, functions, etc. may be realized in software by a processor interpreting and executing a program that realizes each function. Information on the programs, tables, files, etc. that realize each function can be stored in a recording device such as a memory, hard disk, or SSD (Solid State Drive), or on a recording medium such as an IC card, SD card, or DVD.

2. Example of Operation of Work Instruction System Next, an example of operation of the work instruction system 1 having the above-described configuration will be described with reference to FIGS.

2-1 Work Instruction Content Selection Process First, the work instruction content selection process for selecting the content of the work instruction when the worker M1 performs the work will be described with reference to FIG.
FIG. 4 is a flowchart showing the process of selecting the contents of a work instruction.

As shown in FIG. 4, first, worker M1 inputs the ID information assigned to each worker into the device terminal 10 via the input unit 14 (step S11). The input process of the ID information in step S11 may be performed by worker M1 inputting a predetermined voice into the voice device 11. After the input process of the ID information in step S11 is performed, worker M1 is able to use the work instruction system 1 of this example (step S12).

Next, the device terminal 10 transmits the input ID information of the worker M1 to the information determination unit 2 (step S13). Based on the input ID information, the information determination unit 2 acquires information about the worker M1 stored in the worker information storage unit 3, i.e., the worker information. Furthermore, based on the worker information, the information determination unit 2 calculates the proficiency of the worker M1 in each of the work contents A, B, and C. Then, the information determination unit 2 selects the content of the work instruction from the contents A, B, and C of the work instruction recorded in the work content storage unit 4 according to the calculated proficiency (step S14).

Next, the information determination unit 2 transmits the content of the work instruction selected in the processing of step S14 to the device terminal 10 (step S15). This ends the work instruction content selection processing in the work instruction system 1 of this example.

In this way, according to the work instruction system 1 of this example, the information determination unit 2 automatically selects the content of the work instruction that matches the proficiency level of the worker M1 based on the worker information. This saves the worker M1 the trouble of selecting the content of the work instruction.

In the above-mentioned work instruction content selection process, an example has been described in which the information determination unit 2 selects the work instruction content in the process of step 14, but this is not limiting. For example, multiple work instruction contents A, B, and C stored in the work content storage unit 4 may be displayed on the display unit 13 of the device terminal 10, and the worker M1 himself may select the work instruction content that matches his/her level of proficiency.

2-2. Work Content Reporting Process Next, the work content reporting process for reporting actual work content to a third party will be described with reference to FIG.
FIG. 5 is a flowchart showing the work content report process.

First, as shown in FIG. 5, the worker M1 selects the content of the work instruction sent to the device terminal 10 according to the work process or procedure (step S21). When the selection process shown in step S21 is executed, the device terminal 10 and/or the voice device 11 instructs and transmits information according to the content of the work instruction to the worker M1 (step S22).

As shown in FIG. 3A, when worker M1 has a high level of proficiency, work instructions are given using the voice device 11. In contrast, when worker M1 has a low level of proficiency, as shown in FIG. 3B, work instructions are given by image on the display unit 13 of the device terminal 10 and by voice using the voice device 11. This allows appropriate work instructions to be given according to worker M1's level of proficiency, eliminating the time that worker M1 has to spend wondering or thinking about the work content. As a result, work efficiency can be improved.

Next, the worker M1 responds to the work instructions output from the device terminal 10 or the voice device 11 (step S23). The response process in step S23 takes time, which corresponds to the work time for one task. The response process in step S23 is achieved by the worker M1 performing a specific operation set in advance on the device terminal 10 or the voice device 11.

As a response process, for example, first, when worker M1 understands the contents of the work instructions, worker M1 operates the input unit 14 to tap "understood" or verbally responds "understood" via the voice device 11. Next, when the instructed work is completed, worker M1 operates the input unit 14 to tap "completed" or verbally responds "completed" via the voice device 11. Furthermore, if worker M1 wants to confirm the contents of the instructions again, worker M1 operates the input unit 14 to tap "again" or verbally responds "again" via the voice device 11.

In addition, during the response process in step S23, worker M1 can use the device terminal 10 to view the manual stored in the information storage unit 7.

Then, in step S23, the information collecting unit 6 records information on the work content, which includes information on what was done on the device terminal 10 or the voice device 11 by the worker M1, the response time, the contents of the manual viewed, the viewing time, and the number of times (step 24). The information collecting unit 6 records, for example, the time from "Understood" to "Complete" when the worker M1 operates the device terminal 10 or the voice device 11 as the response time. The information collecting unit 6 also records information on the viewing of the manual by the worker M1 during the processing of step S23, i.e., while working.

Next, the information determination unit 2 collects the work content information recorded in the information collection unit 6 and analyzes and organizes it (step S25). In the analysis and organization process of step S25, the information determination unit 2 creates information showing the progress of the work and information showing areas for improvement of the work or product based on, for example, the response time until the work is completed, the contents and time of viewing of the manual, and the number of times it is viewed.

By acquiring the response time until the task is completed, the information determination unit 2 can ascertain the task content that is taking the time of worker M1. Then, if the response time exceeds a preset standard task time, the information determination unit 2 determines that there is an area for improvement in the task or product. In addition, if the time spent viewing the manual or the number of times it is viewed exceeds a preset standard viewing time or standard number of times it is viewed, the information determination unit 2 determines that there is an area for improvement in the task or product, or that there is a defect in the manual.

Then, the information determination unit 2 records the processed work content information, which is the analyzed and organized information, in the information presentation unit 5 (step S26). This completes the work content reporting process in the work instruction system 1 of this example.

By using the information judgment unit 2 to organize and analyze the work content actually performed by the worker M1, it is possible to eliminate the need for the worker M1 to report the work content actually performed to a third party M2, thereby reducing the burden on the worker M1. In addition, the work content performed is collected by the information collection unit 6 from information obtained by the worker M1 operating the device terminal 10 and the voice device 11. This reduces the involvement of human judgment in the collection of work content, and allows the actual work content to be objectively judged.

In addition, the information presented to the third party M2 is information relating to the work content that has been recorded in the information collection unit 6 and organized and analyzed by the information judgment unit 2. This allows only the necessary information to be presented to the third party M2, who can easily grasp the actual progress of the work and any problems with the work content. Furthermore, as described above, information is collected, organized, and analyzed without the intervention of anyone between the worker M1 and the third party M2. This allows the third party to quickly and accurately grasp the work content performed by the worker M1, and to understand the work that is causing the worker M1 difficulty.

Furthermore, when worker M1 is replaced, the information determination unit 2 transmits the work content performed by the previous worker M1, i.e., the processed work content information recorded in the information presentation unit 5, to the device terminal 10 of the successor worker M1. This allows the successor worker M1 to easily understand the work content performed by the previous worker M1. As a result, the handover work of worker M1 can be easily performed, and the effort of reporting when worker M1 is replaced can be reduced.

The information determination unit 2 may also update the worker information stored in the worker information storage unit 3 based on the processed work content information. For example, if the response time is shorter than the standard work time, the information determination unit 2 increases the worker M1's proficiency with respect to that work content. Also, if the manual viewing time or number of views falls below the standard viewing time or number of views, the information determination unit 2 increases the worker M1's proficiency with respect to that work content. As a result, the proficiency of worker M1 is updated based on the actual work content, so a more appropriate proficiency can be selected the next time a similar work is performed.

The device terminal 10 and the voice device 11 may transmit the work content to be instructed to the worker M1 in multiple steps. The information collection unit 6 may then collect the work content actually performed by the worker M1 for each of the multiple steps. This allows the necessary information to be transmitted to the worker M1 in a timely manner for each step, preventing the worker M1 from missing tasks or having to spend extra time checking them.
