Description

Technical Field

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

Background Art

[0002] When performing building standby management work, beginners learn the work procedures during a certain period of OJT (On-the-Job Training). Since the danger level of the work location changes due to differences in weather, not only the work procedures but also the changes in the work environment (weather changes) need to be experienced and learned. Otherwise, the OJT period cannot be completed, and it takes time to reach the level of independent work.

[0003] The system described in Patent Document 1 includes a determination device that determines whether work is feasible. The determination device determines whether the work is possible based on the predicted weather received from the meteorological information system and the input work information. When the work is possible, the determination device sends an email indicating that the work is possible to the information terminal registered in advance by the worker. When the work is impossible, the determination device sends an email indicating that the work is impossible to the information terminals of the worker and the person in charge of the work plan.

[Modes for carrying out the invention]

[0012] The embodiments will be described below with reference to the drawings.

[0013] Embodiment. Figure 1 is a diagram showing the configuration of the work feasibility determination system of Embodiment 1.

[0014] The work feasibility estimation system comprises a work feasibility determination device 21 and worker terminals 31A, 31B, 31C, etc., carried by each worker. The worker terminals 31A, 31B, 31C, etc., are sometimes collectively referred to as worker terminal 31.

[0015] The worker terminal 31 includes a communication device 32, a memory 34, a processor 33, a display device 36, and an input device 37.

[0016] The communication device 32 communicates with the work feasibility determination device 21.

[0017] The input device 37 receives input from the user.

[0018] The display device 36 displays the work feasibility determination result table transmitted from the work feasibility determination device 21.

[0019] The memory 34 stores programs and the like.

[0020] The processor 33 is configured to execute the program stored in the memory 34.

[0021] The work feasibility determination device 21 includes a memory 24, a processor 23, a first communication device 25, and a second communication device 22.

[0022] The first communication device 25 communicates with the worker terminal 31.

[0023] The second communication device 22 communicates with the weather data providing system 11.

[0024] The memory 24 stores a low-risk table and programs and the like. The low-risk table defines weather conditions with low risk for each work.

[0025] The processor 23 is configured to execute the program stored in the memory 24.

[0026] The processor 23 identifies work with low risk at a specified date and time at a specified location based on the low-risk table and the weather data at the specified date and time at the specified location. The weather data includes illuminance. The weather data may further include at least one of rainfall, wind speed, and air temperature.

[0027] Figure 2 is a flowchart showing the processing procedure of the work feasibility determination method of the embodiment. Here, we assume that worker X, who is carrying worker terminal 31A, wants to know whether each task is feasible or not. Worker X is assumed to be carrying worker terminal 31A.

[0028] It is assumed that a work feasibility determination table has been created in advance and is stored in the memory 24 of the work feasibility determination device 21.

[0029] In step S100, worker X inputs the specified date, time, and location for which work is to be determined via the input device 37 at the worker terminal 31A. If the specified date is the current date, the specified time is the current time, and the specified location is the worker X's workplace, which are already registered, step S100 can be omitted.

[0030] In step S101, the processor 33 transmits a decision request signal, including the user ID, specified date, specified time, and specified location, to the work feasibility determination device 21 via the communication device 32.

[0031] In step S102, the first communication device 25 of the work feasibility determination device 21 receives a determination request signal that includes a user ID, a specified date, a specified time, and a specified location.

[0032] In step S103, the processor 23 of the work feasibility determination device 21 transmits a request signal for the provision of weather data, including the specified date, specified time, and specified location, to the weather data provision system 11 via the second communication device 22.

[0033] In step S104, the weather data provision system 11 receives a request signal for weather data, which includes a specified date, a specified time, and a specified location.

[0034] In step S105, the weather data provision system 11 transmits weather data for the specified date, time, and location.

[0035] In step S106, the second communication device 22 of the work feasibility determination device 21 receives weather data for the specified date, time, and location.

[0036] Figure 3 shows an example of weather data for a specified date, time, and location received from the weather data provision system 11. In the example in Figure 3, rainfall, wind speed, temperature, sunrise time, sunset time, and weather are specified for each time on the specified date at the specified location. However, for the specified location, it is sufficient to provide the sunrise time, sunset time, rainfall, wind speed, temperature, and weather for the specified date and time.

[0037] In step S107, the processor 23 of the work feasibility determination device 21 estimates the illuminance for the specified date, specified time, and specified location using the received weather data.

[0038] Figure 4 shows an example of illuminance estimated using the meteorological data from Figure 3. In the example in Figure 4, illuminance is estimated for each time period, but it is also possible to estimate only the illuminance for a specified time.

[0039] In step S108, the processor 23 of the work feasibility determination device 21 refers to a low-risk table that defines low-risk weather conditions for each type of work, determines whether each type of work is feasible at the specified location on the specified date and time, and creates a work feasibility determination result table. For example, the processor 23 identifies a type of work as low-risk work for the specified location on the specified date and time if the rainfall, wind speed, temperature, and illuminance at the specified location on the specified date and time meet the low-risk conditions defined in the low-risk table, and creates a work feasibility determination result table.

[0040] Figure 5 shows an example of a low-risk table. For each task name, which consists of major and minor items, low-risk rainfall, low-risk wind speed, low-risk temperature, and low-risk illumination are specified. The low-risk temperature condition is specified for the daily equipment inspection of the chilled water pump (machine room) to prevent heatstroke among workers in the machine room, which tends to get hot. The low-risk rainfall, wind speed, and temperature conditions are specified for the daily equipment inspection of the exhaust fan (rooftop) to prevent workers from getting wet in the rain, being blown away, or suffering from heatstroke on the rooftop. The low-risk rainfall, wind speed, and temperature conditions are specified for the monthly equipment inspection of the sub-substation (rooftop) to prevent rainwater from entering the inside of the doors, preventing the doors from being opened and closed freely due to wind, and preventing workers from suffering from heatstroke, as these tasks require opening and closing the doors.

[0041] In step S109, the processor 23 of the work feasibility determination device 21 transmits the work feasibility determination result table to the worker terminal 31A via the first communication device 25.

[0042] In step S110, the communication device 32 of the worker terminal 31A receives the work feasibility determination result table.

[0043] In step S111, the processor 33 of the worker terminal 31 displays the work feasibility determination result table on the display device 36.

[0044] Figure 6 shows an example of a work feasibility determination result table. For each work name, which consists of major and minor items, the feasibility of the work is indicated.

[0045] Figure 7 is a flowchart illustrating the illuminance estimation procedure in step S107 of Figure 2.

[0046] In step S301, the processor 23 creates input data from the received weather data, consisting of a specified time, sunrise time at a specified location on a specified date, sunset time at a specified location on a specified date, and weather conditions at a specified location on a specified date and time.

[0047] In step S302, the processor 23 uses a trained model stored in memory 24 to estimate the illuminance at a specified location on a specified date and time from the input data. The trained model is a model that estimates the illuminance at a given time from the weather at that time, sunrise time, sunset time, and weather conditions at that time. For example, a neural network can be used as the trained model.

[0048] Figure 8 is a flowchart illustrating the training procedure for creating a pre-trained model.

[0049] In step S201, the processor 23 acquires training data consisting of input data consisting of the time of observation, sunrise time, sunset time, and weather at the time of observation, and training data consisting of illuminance at the time of observation. For example, a training data set can be made with a time of observation of 12:00, sunrise time of 4:30, sunset time of 18:47, weather at the time of observation of 2 mm / h (rainfall), northeast 1 mm (wind speed), 28°C (temperature), sunny (weather), and illuminance at the time of observation of 100,000 lux. Weather data can be provided from a weather data provision system. Illuminance data can be, for example, data from an illuminance sensor installed in a building.

[0050] In step S202, the processor 23 uses the training data to create a trained model that estimates the illuminance at the time of interest from the time of interest, sunrise time, sunset time, and weather conditions at the time of interest.

[0051] According to this embodiment, it is possible to determine whether or not to carry out work based on changes in the degree of work risk due to external environmental factors such as weather, and to notify novice workers of whether or not to carry out the work. As a result, even novice workers can anticipate work risks in unfamiliar weather conditions.
