Description

The present invention relates to a work management system and a work management method.

In general, a worker who is in charge of cleaning or inspecting a building or the like writes down a work record, such as what has been cleaned, in a report after completing the work. Also, a work management system has been developed in which this report is entered electronically using a terminal.
On the building manager side, the performance data input by the worker is checked, whether or not the performance data has been input, and correction of the performance data is performed. Since building managers must check the work performance of multiple buildings, work management systems that manage work performance on computer terminals are being introduced in order to prevent omissions in checking work performance.

Japanese Patent Laid-Open No. 2002-200002 describes a technique for managing work results from a work trajectory by grasping the position of a worker using a sensor built into a terminal carried by the worker.

JP 2017-68450 A

In the technology described in Patent Document 1, the system acquires the position information of the worker using the sensor built into the terminal by having the worker carry a terminal capable of communication while working. . Therefore, workers must always have a terminal with them while they are working, but in the case of workers who are in charge of fast-moving tasks such as building cleaning, there is a possibility that they may lose their terminals during work. Such a system is not suitable. Also, if there is a problem such as the worker forgetting to carry the terminal or the power of the terminal is not turned on, the position of the worker cannot be grasped.

In addition, workers who are in charge of cleaning and inspecting buildings are often in charge of multiple types of work. is difficult to determine. Therefore, there is a problem that work content cannot be managed only by making the worker carry a terminal for position detection.

SUMMARY OF THE INVENTION An object of the present invention is to provide a work management system and a work management method that can easily and satisfactorily manage the daily work of workers who are in charge of cleaning and inspecting buildings.

[3. Work performance management processing operation]
FIG. 3 is a flow chart showing an example of processing in the monitoring server 10 of the work performance management system of this example.
First, the monitoring camera 3a or 3b acquires a monitoring image (step SA1), and the monitoring image is transmitted from the monitored site 1 to the monitoring server 10 (step SA2). When the monitoring image transmitted from the monitored site 1 is received by the monitoring server 10, processing by the monitoring device 11 of the monitoring server 10 is started (step SB1).

In the monitoring device 11, the building name extraction unit 14a of the work management processing unit 14 extracts the names of buildings, facilities, etc. from the IP address storage area 16a and building information storage area 16b of the data storage device 16, and the extracted names is stored in the monitoring device 11 (step SB2). The names of buildings, facilities, etc. are obtained based on the image data received by the image obtaining section 15a of the position information processing section 15 and the IP addresses of the monitored site 1 and the monitoring cameras 3a and 3b.

Next, the image acquisition unit 15a of the position information processing unit 15 determines whether or not the worker is shown in the acquired image data (step SB3). Determination of whether or not the worker is shown is made by identifying whether or not a person wearing the worker's uniform registered in advance is included in the image, for example. When the operator cannot be determined in step SB3 (No in step SB3), the monitoring device 11 returns to the monitoring image reception process in step SB1.

Then, when the worker is determined in step SB3 (Yes in step SB3), the work management processing unit 14 of the monitoring device 11 extracts work items from the schedule in the schedule storage area 16d for the extracted building name of the monitored site 1. Extract (step SB4). The work management processing unit 14 also extracts the start time and end time of the work described in the schedule.
Then, the work management processing unit 14 determines whether the work item extracted from the schedule is cleaning or inspection (step SB5).

In step SB5, when the schedule of the corresponding building is cleaning ("cleaning" in step SB5), the work management processing unit 14 determines the time when the worker enters floor a 2a based on the camera image. The start time is extracted and stored in the work position information storage area 16f (step SB6). Simultaneously with the extraction of the start time by the work management processing unit 14, the trajectory extraction unit 15b of the position information processing unit 15 extracts the work trajectory (movement trajectory) of the worker from the image of the monitoring camera 3a, and stores the floor plan. Store in area 16c (step SB7). Furthermore, based on the camera image, the work management processing unit 14 extracts the work end time, which is the time when the worker left the a floor 2a, and stores it in the work position information storage area 16f (step SB8).

After that, the work management processing unit 14 uses the acquired trajectory information data to determine whether or not the worker has a defective work. Specifically, the work management processing unit 14 determines whether or not the trajectory indicated by the acquired trajectory information data has passed through the vicinity of all reference points preset in the floor plan (Step SB9). .

In step SB9, if the vicinity of all reference points preset in the floor plan has been passed (Yes in step SB9), it is determined that the cleaning work has been performed correctly, and the work management processing unit 14 checks the corresponding area. (floor) is given an identifier of the work area (work completion area) and stored in the work result storage area 16h. Then, the work management processing unit 14 creates a work report indicating that the cleaning work is normal based on the identifier of the work area (work completion area), and ends the process (step SB10).
On the other hand, in step SB9, when the vicinity of the reference point set in the floor plan is not passed (No in step SB9), it is determined that the cleaning work is not performed correctly, and the work management processing unit 14 An identifier of an unworked area is given to the area (floor) to be worked on and stored in the work result storage area 16h. Then, the work management processing unit 14 sends an e-mail indicating that the work is incomplete (work is defective) to the e-mail receiving terminal 17 of the manager 18 (step SB11). Then, the work management processing unit 14 creates a work report indicating that the cleaning work is inadequate based on the identifier of the unworked area, and ends the process (step SB10).

In addition, if the work item is inspection as determined in step SB5 ("inspection" in step SB5), the work management processing unit 14, based on the camera image, performs the work at the time when the worker entered floor b 2b. is extracted and stored in the work position information storage area 16f (step SB12). Simultaneously with the extraction of the start time of the work management processing unit 14, the trajectory extraction unit 15b of the position information processing unit 15 extracts the work trajectory (movement trajectory) of the worker from the image of the monitoring camera 3b, and stores the floor plan. Store in area 16c (step SB13). Furthermore, based on the camera image, the work management processing unit 14 extracts the work end time, which is the time when the worker left floor b 2b, and stores it in the work position information storage area 16f (step SB14).

After that, the work management processing unit 14 uses the acquired trajectory information data to determine whether or not the worker has a defective work. Specifically, the work management processing unit 14 extracts the entry time and the exit time from the reference area preset in the floor plan from the trajectory indicated by the acquired trajectory information data, and stores the work position information. Store in area 16f (step SB15). The reference area here is the area where the inspection facilities 5a and 5b are installed.
Then, the work management processing unit 14 determines whether or not the user has stayed in each reference area of the floor plan for a preset predetermined time (step SB16). Here, the preset predetermined time is the minimum time (for example, about 10 minutes) required to inspect the inspection facilities 5a and 5b existing in each reference area.

In step SB16, if the stay time in all the reference areas preset in the floor plan is equal to or longer than the predetermined time (Yes in step SB16), it is determined that the inspection work has been performed correctly, and the work management processing unit 14 A work area (work completion area) identifier is assigned to the corresponding area (floor) and stored in the work result storage area 16h. Then, based on the identifier of the work area (work completion area), the work management processing unit 14 creates a work report indicating that the inspection work is normal, and ends the process (step SB10).
On the other hand, in step SB16, if the stay time in the reference area set in the floor plan is less than the predetermined time (No in step SB16), it is determined that the inspection work has not been performed correctly, and the corresponding area (floor) An identifier of the unworked area is added and stored in the work result storage area 16h. Then, based on the identifier of the unworked area, the work management processing unit 14 sends an e-mail indicating that the work is incomplete (work is defective) to the e-mail receiving terminal 17 of the manager 18 (step SB17). Then, the work management processing unit 14 creates a work report indicating that the inspection work is inadequate, and terminates the process (step SB10).

[4. Work schedule example]
FIG. 4 shows an example of a work schedule that is a work schedule stored in the work schedule data storage area 16d. This work schedule is displayed on the screen of the administrator terminal 9 .
The work schedule includes a work schedule (work name) area 111, a work area (site name) area 112, a scheduled worker area 113, a scheduled work date and time area 114, and a scheduled work time area 115.

For example, the top column in FIG. 4 shows the work area (site name), scheduled worker, scheduled work date and time, and scheduled work time for "cleaning work A01". The scheduled work time is automatically set by the work management processing unit 14 according to the work area and the work content in the work area. When the work management processing unit 14 sets the scheduled work time, it uses the number of reference points and reference areas that exist in each work area. Reference points and reference areas existing in the work area will be described later (explained in FIGS. 6 and 7).
When the work schedule data storage area 16d stores work schedule data, which is the work schedule shown in FIG. 4, an identifier corresponding to each piece of information is stored.

In addition, although FIG. 4 shows a state in which all items have been fixed as a schedule, information that has not been fixed may be left blank. For example, when the worker who will carry out the work is undetermined, the scheduled worker area 113 may be left blank. As for the area 114 of scheduled work date and time, only the work day may be set as a schedule, and the work time may not be set. Alternatively, instead of setting the date, the day of the week on which the work is to be performed may be set in the schedule.

[5. Example of work report]
FIG. 5 shows an example of a work report created by the work management processor 14. As shown in FIG. This work report is displayed on the screen of the administrator terminal 9 .
The work report includes a work name area 121, a work area (site name) area 122, an executing worker area 123, a start date/time area 124, an end date/time area 125, a status area 126, and a work trajectory display button area. 127, and an area 128 for a work image display button.
For example, the top column in FIG. 5 shows the work area (site name), execution worker, start date and time, end date and time, and status for "cleaning work A01". The status column 126 indicates whether the cleaning work or inspection work has been completed (OK) or has not been completed (NG).

The information on whether the cleaning work or inspection work is completed or not is not simply indicative of whether or not the work has been done at that location. That is, when it is estimated that the work has been performed correctly based on the work time, etc., the area is regarded as a work completed area, and the work management processing unit 14 sets the work completion (OK). If it is estimated that the work will not be performed correctly based on the work time, etc., the work management processing unit 14 sets the work incomplete (NG) as an unworked area where the work is not completed.
These work reports are sent from the communication device 12, which is a work report output unit, with the work area identifier (OK or NG), the worker who performed the work, the work schedule, and the work performed. The date and time data thus obtained are output in association with each other, so that the data as shown in FIG. 5 is created.

In the column of the worker who executed the work in the work report, when the column of the corresponding work in the work schedule (Fig. 4) contains the scheduled work worker, the work management processing unit 14 Enter Alternatively, the results of identifying the workers who actually performed the work may be acquired by the work management processing unit 14 from the outside and added to the work report. For example, the work management processing unit 14 acquires the results determined by a building management system that manages entering and exiting a work area using a card key, etc., and the work management processing unit 14 executes the work of the work report. Add to the column of Alternatively, the worker may be identified by image recognition of images captured by the monitoring cameras 3a to 3b provided in this system.

When the button 106a in the work trajectory column 106 is pressed, the screen of the administrator terminal 9 displays the trajectory of the corresponding work on the floor plan.
Further, when the button 106a in the image field 107 is pressed, the screen of the administrator terminal 9 displays the camera image during the corresponding work. These loci on the floor plan and camera images are transmitted from the data storage device 16 to the administrator terminal 9 .

In the flowchart of FIG. 8, the same step numbers as those of each process shown in FIG. 5 are given.
In the case of the flowchart of FIG. 8, when monitoring images are acquired by the monitoring cameras 3a and 3b (step SA1), the transmission of the monitoring images is started (step SA2), but the transmission of the monitoring images is low-frequency transmission. The low-frequency transmission is, for example, transmission of one frame image captured by the monitoring cameras 3a to 3b once every one to several seconds.

In step SB4, the monitoring server 10 extracts work items from the schedule, and if the schedule exists, instructs the monitoring camera 3a or 3b that is transmitting images to perform high-frequency transmission (from step SB4). transmission of instructions to step SA3).
The monitor camera 3a or 3b that receives this high-frequency transmission instruction starts high-frequency transmission, for example, 15 frames per second or 30 frames per second (step SA3).

Furthermore, when the monitoring server 10 extracts the work end time in step SB8 or SB14, it instructs the monitoring camera 3a or 3b that is transmitting images to perform low-frequency transmission (from steps SB8 and SB14 to step SA4). instructions).
In the monitor camera 3a or 3b that has received this high-frequency transmission instruction, a process of returning to low-frequency transmission is performed (step SA4).
Other parts of the flowchart of FIG. 8 are processed in the same manner as in the flowchart of FIG.

By switching the transmission rate in this way, image data is transmitted at high frequency while it is necessary to accurately determine the work trajectory of the worker, and image data is transmitted at low frequency during other periods. Thus, the load on the network (Internet N) connecting the monitored site 1 and the monitoring server 10 can be reduced.

Further, in the system configuration shown in FIG. 1, the monitoring device 11 is provided in the monitoring server 10 at a location remote from the sites 1 to 1n to be monitored so as to manage the work results of the workers. On the other hand, a monitoring device and a data storage device may be provided in the buildings of the monitored sites 1 to 1n, and part or all of the processing performed by the monitoring server 10 may be performed in the building.

FIG. 9 is a diagram showing an example of the system configuration in this case. In FIG. 9, portions corresponding to those in FIG. 1 are denoted by the same reference numerals.
In the example of FIG. 9, a monitored site (building) 1 is provided with a monitoring device 30. In the example of FIG. This monitoring device 30 is composed of, for example, the computer device C shown in FIG. A data storage device 34 is also connected to the monitoring device 30 .

The work management processing unit 32 and the position information processing unit 33 have the same configuration as the work management processing unit 14 and the position information processing unit 15 on the monitoring server 10 side. The data storage device 34 also has the same configuration as the data storage device 16 on the monitoring server 10 side.
However, only the image data from the monitoring cameras 3a and 3b in the same building 1 are transmitted to the monitoring device 30, and work performance management is performed only for the floors 2a and 2b in the same building 1. FIG.

Then, a work report as a work result management result obtained by the monitoring device 30 and an image during work are transmitted to the monitoring server 10 side. In the case of the configuration shown in FIG. 9, the processing in the work management processing section 14 and the position information processing section 15 of the monitoring server 10 may be omitted, and the data storage device 16 may simply store the transmitted data. . In the case of the configuration shown in FIG. 9, either the building-side monitoring device 30 or the server-side monitoring device 11 may send mail to the administrator terminal 9 or the mail receiving terminal 17 .

Further, in the above-described embodiment, an example has been described in which a worker's uniform or the like is detected from an image captured by a camera to detect that the worker is a worker. On the other hand, for example, the faces of workers may be registered in advance, and individual workers may be identified from the faces in the images captured by the camera. In addition, in conjunction with the equipment that manages the entry and exit of each area, it is possible to detect the entry and exit of each worker by operating the card key when entering and leaving each area, and the camera image A work trajectory based on this may be detected.

Further, the above-described embodiment has been described in detail for easy understanding of the present invention, and is not necessarily limited to those having all the described configurations. 1 and 9 show only those control lines and information lines that are considered necessary for explanation, and not all control lines and information lines are necessarily shown on the product. In practice, it may be considered that almost all configurations are interconnected. In addition, in the flowcharts shown in FIGS. 3 and 8, the execution order of some processing steps may be changed or some processing steps may be executed at the same time within a range that does not affect the processing results of the embodiment. can be

Moreover, the configurations described in the above embodiments may be realized by software, in which a processor interprets and executes programs for realizing respective functions. Information such as a program that implements each function can be placed in a memory, a recording device such as a hard disk or an SSD, or a recording medium such as an IC card, an SD card, or an optical disc.
