Description

Technical Field

[0001] The present disclosure relates to a work progress management device, a work progress management system, and a work progress management method.

Background Art

[0002] The resident management work of building facilities includes regular work such as daily patrol inspections and irregular work such as equipment failure response, requests from building users, and response to claims. Among the regular work, for the in-house visual patrol inspection that does not require knowledge of equipment technology and the meter reading work of measuring instruments, since there are fixed work and movement routes, the person in charge of the work is often a beginner in the resident management work. Also, in order to reliably complete the daily work, as the nature of the regular work, it is important to keep the required time and proceed as planned.

[0003] A beginner in regular work cannot immediately respond when something unexpected occurs, and there is a high possibility that the work will be delayed. Since a beginner may not understand the overall work, they may not know the impact on other work and may forget to inform the relevant parties that the work is delayed. Therefore, the business manager needs to manage the work progress of the workers.

[0004] As a method of managing the work progress of workers, for example, a method of estimating the work progress from the current position of the worker can be considered.

[0005] Also, Patent Document 1 discloses a technique for detecting where a worker has stopped based on the number of steps of the worker.

Embodiments for Carrying out the Invention

[0014] Hereinafter, the embodiments will be described with reference to the drawings. Embodiment 1. FIG. 1 is a diagram showing the configuration of the work progress management system of Embodiment 1.

[0015] The work progress management system comprises an administrator terminal 11, a work progress management device 21, and a worker terminal 31 carried by the worker.

[0016] The administrator terminal 11 comprises a communication device 12, a display device 14, an input device 13, a memory 15, and a processor 16.

[0017] The communication device 12 communicates with the work progress management device 21. The communication device 12 sends an investigation request signal containing the worker's name and the work name to the work progress management device 21. The communication device 12 receives the progress of the work being performed by the worker from the work progress management device 21.

[0018] The input device 13 accepts input from the administrator regarding the name of the worker whose progress they wish to check and the name of the task.

[0019] The display device 14 displays the progress of the worker's work. Memory 15 stores programs and other data.

[0020] The processor 16 is configured to execute a program stored in memory 15. The processor 16 transmits a survey request signal, including the worker's name and the task name, to the work progress management device 21 via the communication device 12. The processor 16 receives the progress of the worker's ongoing task via the communication device 12 and displays the progress of the worker's ongoing task on the display device 14.

[0021] The worker terminal 31 includes a communication device 32, a memory 34, a processor 33, and a sensor 35.

[0022] The communication device 32 communicates with the work progress management device 21. The communication device 32 receives a step count transmission request signal from the work progress management device 21. The communication device 32 transmits a step count notification signal to the work progress management device 21.

[0023] The sensor 35 measures the number of steps taken by the worker carrying the worker terminal 31. Memory 34 stores time-series data of the worker's step count measured by sensor 35. Memory 34 also stores programs and other data.

[0024] The processor 33 is configured to execute a program stored in the memory 34. The processor 33 reads time-series data of steps for a predetermined period of time, going back from the time the step count transmission request signal was received from the memory 34, and transmits a step count notification signal containing the read step count time-series data as a step count performance pattern to the work progress management device 21 via the communication device 32.

[0025] The work progress management device 21 includes a memory 24, a processor 23, a first communication device 25, and a second communication device 22.

[0026] The first communication device 25 communicates with the worker terminal 31. The first communication device 25 receives a step count notification signal, which includes the worker's step count history pattern, transmitted from the worker terminal 31. The first communication device 25 transmits a step count transmission request signal to the worker terminal 31.

[0027] The second communication device 22 communicates with the administrator terminal 11. The second communication device 22 receives the investigation request signal transmitted from the administrator terminal 11.

[0028] Memory 24 stores the step count characteristic patterns of each worker for each of the multiple tasks for managing building facilities. The step count characteristic patterns are represented by time-series data. Memory 24 stores a user table that defines the addresses of each worker's terminal. Memory 24 also stores programs and other data.

[0029] The processor 23 is configured to execute a program stored in memory 24. The processor 23 receives a survey request signal through the second communication device 22, refers to the user table to identify the address of the worker terminal of the worker name included in the survey request signal, and sends a step count transmission request signal to the worker terminal through the first communication device 25.

[0030] The processor 23 estimates the progress of the worker's current task by comparing the received worker's step count pattern with the step count feature pattern of the worker's current task stored in memory 24. More specifically, the processor 23 detects portions of the time-series data of the worker's step count pattern that match or are similar to the time-series data of the worker's current task's step count feature pattern, and estimates the progress of the task as the ratio of the time of the detected portion to the total time the worker has spent on the current task. Here, the processor 23 may also determine the total time the worker has spent on the current task based on the time-series data of the step count feature pattern of the worker's current task. The processor 23 transmits the estimated progress of the worker's current task to the administrator terminal 11 via the second communication device 22.

[0031] Figure 3 shows the travel route for monthly electrical inspections. Figure 4 shows the step count characteristic pattern F1 for monthly electrical inspections. As shown in Figure 4, during monthly electrical inspections, workers alternate between traveling and inspecting electrical equipment. Travel is short in duration, and the number of steps increases during travel. Electrical equipment inspection is long in duration, and the number of steps decreases during the inspection.

[0032] Figures 2 and 5 show the movement routes for temperature checks within the building. Figure 6 shows the step count characteristic pattern F2 for temperature checks within the building. As shown in Figure 6, during temperature checks within the building, workers walk for about 40 seconds, stop for about 15 seconds, and measure the temperature. This is repeated. When moving between floors, escalators are used, so the number of steps is reduced.

[0033] Figure 7 shows the travel route for exhaust fan inspection. Figure 8 shows the step count characteristic pattern F3 for exhaust fan inspection. As shown in Figure 8, during exhaust fan inspection, the worker moves from the disaster prevention center to the rooftop and visually inspects or checks for abnormal noises of the exhaust fans scattered on the rooftop. The worker's step count is high when moving from the disaster prevention center to the rooftop and from the rooftop back to the disaster prevention center. During the inspection, the step count decreases.

[0034] Figure 9 shows the travel route for verifying water meter readings. Figure 10 shows the step count characteristic pattern F4 for verifying water meter readings. As shown in Figure 10, during water meter reading verification, the worker moves from the disaster prevention center to the location where the water meter is installed, reads the reading from the water meter, and records it. This is repeated.

[0035] Figure 11 shows the movement route for escalator activation. Figure 12 shows the step count characteristic pattern F5 for escalator activation. As shown in Figure 12, when escalator activation, the worker starts from the disaster prevention center, performs the escalator activation work, and moves to the next escalator. The worker's step count increases when moving from the disaster prevention center to the installation location of the west side escalator group, when moving from the installation location of the west side escalator group to the installation location of the east side escalator group, and when moving from the installation location of the east side escalator group to the disaster prevention center. The worker's step count decreases while sequentially activating the west side escalators and while sequentially activating the east elevators.

[0036] Figure 13 is a flowchart showing the processing procedure of the work progress management method of Embodiment 1.

[0037] In step S100, the processor 23 in the work progress management device 21 creates step count characteristic patterns for each task, as shown in Figures 4, 6, 8, 10, and 12. These step count characteristic patterns may be created, for example, from time-series data of the number of steps obtained by having an operator actually perform the task.

[0038] In step S101, the sensor 35 in the worker terminal 31 starts measuring the worker's step count, and the processor 33 executes a step counting application to store the worker's step count in the memory 34.

[0039] In step S102, at the administrator terminal 11, the administrator enters the worker's name and the work name of the worker to be investigated through the input device 13.

[0040] In step S103, at the administrator terminal 11, the processor 16 transmits an investigation request signal including the worker's name and the work name to the work progress management device 21 via the communication device 12.

[0041] In step S104, the processor 23 in the work progress management device 21 receives an investigation request signal through the second communication device 22.

[0042] In step S105, the processor 23 in the work progress management device 21 refers to the user table stored in memory 24 to identify the address of the terminal (worker terminal) of the worker name included in the investigation request signal. Figure 14 shows an example of a user table. An address of the worker terminal is assigned to each worker (designation or ID).

[0043] In step S106, the processor 23 in the work progress management device 21 transmits a step count transmission request signal to the identified worker terminal 31 via the first communication device 25.

[0044] In step S107, the processor 33 in the worker terminal 31 receives a step count transmission request signal through the communication device 32.

[0045] In step S108, at the worker terminal 31, the processor 33 reads the number of steps for the past X hours from the memory 34 from the time the step count transmission request signal was received. X hours can be, for example, 3 hours. The processor 33 transmits a step count notification signal containing the time-series data of the number of steps for the past X hours as a step count performance pattern FX to the work progress management device 21 via the communication device 32. Figure 15 shows an example of the data included in the step count notification signal. The step count notification signal includes a set of data for the day, time, number of steps, and user ID.

[0046] In step S109, the processor 23 in the work progress management device 21 receives a step count notification signal through the first communication device 25.

[0047] In step S110, the processor 23 in the work progress management device 21 creates a step count performance pattern FX based on the step count notification signal and the number of steps taken over the past X hours. Figure 16 shows an example of the step count performance pattern FX. The step count performance pattern, like the step count feature pattern, is represented by time-series data.

[0048] In step S111, in the work progress management device 21, the processor 23 reads the step count feature pattern FY of the work name included in the investigation request signal from the memory 24.

[0049] In step S112, the processor 23 in the work progress management device 21 calculates the worker's work progress by comparing the step count actual pattern FX with the step count feature pattern FY. Figure 17 shows an example of how the worker's work progress is calculated. In the example in Figure 17, the work name included in the survey request signal is "Water volume meter value confirmation" and the step count feature pattern FY is F4.

[0050] The processor 23 detects portions of the time series data of the step count performance pattern FX that match or are similar to the time series data of the step count feature pattern FY. In the example in Figure 17, the time series data for the past 7 minutes, starting from the latest time of the step count performance pattern FX, is similar to the time series data for the past 7 minutes of the step count feature pattern FY.

[0051] The processor 23 estimates the progress of the work being performed as the ratio of the detected portion of time to the total time of the work being performed. In the example in Figure 17, the detected portion of time is 7 minutes, and the time required for the work being performed, "checking water meter readings," is 11 minutes, so the progress of the work is estimated to be 7 / 11.

[0052] Here, the determination of similarity in time-series data can be made using methods such as waveform pattern matching.

[0053] For example, processor 23 calculates the similarity R(k) between the time series data of steps in the step count performance pattern from time k × Δt hours prior to the latest time tc to the latest time tc (i.e., tc - k × Δt ≤ tx ≤ tc) and the time series data of steps in the step count feature pattern FY from time 0 to time k × Δt hours later (i.e., 0 ≤ ty ≤ k × Δt). Processor 23 sequentially changes k to calculate R(k) and identifies the k that maximizes R(k) as Km. Processor 23 can determine that the time series data of the step count performance pattern FX, starting from the latest time, for the past Km × Δt minutes is similar to the time series data of the step count feature pattern FY for the past Km × Δt minutes. As the similarity R(k), for example, the correlation between the two time series data can be used.

[0054] The processor 23 can determine the duration of an ongoing task based on the time-series data of the step count feature pattern of the task being performed. For example, in the example in Figure 17, the interval of consecutive non-zero values ​​in step count feature pattern F4 is "11 minutes," so the processor 23 can determine that the duration of the ongoing task "Water meter reading confirmation" is "11 minutes." In "Monthly electrical inspection" in Figure 4, the interval of consecutive non-zero values ​​in step count feature pattern F1 is "120 minutes," so the processor 23 can determine that the duration of "Monthly electrical inspection" is "120 minutes." In "Building temperature patrol" in Figure 6, the interval of consecutive non-zero values ​​in step count feature pattern F2 is "60 minutes," so the processor 23 can determine that the duration of "Building temperature patrol" is "60 minutes." In Figure 8, for "Exhaust Fan Inspection," the interval of consecutive non-zero steps in step count feature pattern F3 is "40 minutes," so the processor 23 can determine that the duration of "Exhaust Fan Inspection" is "40 minutes." In Figure 12, for "Escalator Startup," the interval of consecutive non-zero steps in step count feature pattern F5 is "30 minutes," so the processor 23 can determine that the duration of "Escalator Startup" is "30 minutes."

[0055] In step S113, the processor 23 in the work progress management device 21 transmits a work progress notification signal, including the worker's work progress, to the administrator terminal 11 via the second communication device 22.

[0056] In step S114, the processor 16 in the administrator terminal 11 receives a work progress notification signal through the communication device 12.

[0057] In step S115, the processor 16 in the administrator terminal 11 displays the worker's work progress included in the work progress notification signal on the display device 14.

[0058] As described above, according to this disclosure, the progress of a worker can be estimated remotely without installing any special indoor equipment by comparing the walking characteristic pattern of each worker's task with the walking performance pattern of the task the worker is currently performing.
