[0021] The control device 3 is, for example, a server that functions as a cloud, and includes a communication unit 31, a storage unit 32, and a control unit 33. The communication unit 31 communicates with the position measurement tags 111, environment measurement sensors 12, human measurement sensors 13, equipment status measurement sensors 14, and alarm devices 15 in the monitored space 1, as well as with the notification system 2. The storage unit 32 stores various data and programs used by the control unit 33 of the control device 3.

[0022] The control unit 33 calculates the spatial environment and equipment status within the space based on various data acquired from the position measurement tags 111, the environment measurement sensors 12, the occupancy measurement sensors 13, and the equipment status measurement sensors 14 within the monitoring space 1. Furthermore, the control unit 33 notifies the alarm device 15 within the monitoring space 1 of the operating status of the equipment and the spatial status within the space based on the calculation results. Furthermore, the control unit 33 causes the display device 21 of the notification system 2 to display the operating status of the equipment and the spatial status within the space based on the calculation results.

[0023] In detail, as shown in FIG. 2, the control unit 33 includes a data acquisition unit 331, a space state calculation unit 332, a position information management unit 333, a device state management unit 334, and a display control unit 335.

[0024] The data acquisition unit 331 acquires various data from the position measurement tags 111, the environment measurement sensors 12, the occupancy measurement sensors 13, and the equipment status measurement sensors 14 in the monitoring space 1 shown in Fig. 1. The space status calculation unit 332 calculates the space status in the monitoring space 1 from the gaseous environment data measured by the environment measurement sensors 12 and the occupancy data measured by the occupancy measurement sensors 13.

[0025] The location information management unit 333 manages the location information of the moving object 11 in space according to the location data of the moving object 11 measured by the location measurement tag 111 shown in Fig. 1. The equipment status management unit 334 manages the operation status of the equipment according to the operation data of the equipment measured by the equipment status measurement sensor 14 shown in Fig. 1. The equipment status management unit 334 also acquires the work schedule of the equipment from a server or terminal device external to the control device 3, and determines the current work content or future work schedule of the equipment. The display control unit 335 controls the display content of the display device 21 of the notification system 2 shown in Fig. 1.

[0026] Each function of the control unit 33 of the control device 3 shown in Fig. 2 is realized by executing a program stored in the storage unit 32 of the control device 3 shown in Fig. 1. The hardware configuration of the control device 3 for executing the program will be described below with reference to Fig. 3.

[0027] The control device 3 includes a communication device 3301, a storage device 3302, a memory 3303, and a processor 3304. The communication device 3301, the storage device 3302, the memory 3303, and the processor 3304 are connected to each other via a bus 3305.

[0028] The communication device 3301 communicates with the position measurement tags 111, the environmental measurement sensors 12, the human measurement sensors 13, the equipment status measurement sensors 14, the alarm device 15, and the notification system 2 in the monitored space 1 via a network. The communication device 3301 can be configured using various devices equipped with a communication method connectable to a network, such as a wired or wireless local area network (LAN). The storage device 3302 is a device that stores various programs executed by the processor 3304 and various data acquired by the communication device 3301 from the position measurement tags 111, the environmental measurement sensors 12, the human measurement sensors 13, and the equipment status measurement sensors 14. The storage device 3302 can be configured using storage devices such as a hard disk drive (HDD) or a solid state drive (SSD).

[0029] The memory 3303 is a storage element for loading various programs stored in the storage device 3302. The memory 3303 can be configured using, for example, a storage element and a storage medium such as a random access memory (RAM) or a volatile or non-volatile semiconductor memory such as a flash memory. The processor 3304 reads out the various programs stored in the storage device 3302, loads them into the memory 3303, and executes them. The processor 3304 can be configured using, for example, a processing device such as a central processing unit (CPU) or a micro-processing unit (MPU).

[0030] Next, an example of the configuration of the notification screen 211 displayed on the display device 21 of the notification system 2 is shown in Fig. 4. The notification screen 211 displays the status of the monitoring space 1. The notification screen 211 includes a date and time display section 212 and an information presentation section 213. The date and time display section 212 displays the current date and time of the monitoring space 1. In Fig. 4, for example, "2024 / XX (Wednesday) 11:05 AM" is displayed.

[0031] The information presentation unit 213 includes a management location selection unit 2131 and a video display unit 2132. The management location selection unit 2131 displays buttons, selection items, etc. for selecting a location of which the user wants to check the current status within the monitoring space 1 to be managed. For example, in Fig. 4, the management location selection unit 2131 displays a facility selection button 2131a, a floor selection button 2131b, a location selection button 2131c, a change button 2131d, and an information update button 2131e.

[0032] The facility selection button 2131a, floor selection button 2131b, and location selection button 2131c present options for the confirmation target in a pull-down format. The change button 2131d confirms the confirmation target selected with the facility selection button 2131a, floor selection button 2131b, and location selection button 2131c, and changes the management target presented in the video display unit 2132. The information update button 2131e allows the user to manually update the information for the confirmation target selected with the facility selection button 2131a, floor selection button 2131b, and location selection button 2131c.

[0033] The video display section 2132 displays a spatial shape 2133, generation order marks 2134a to 2134d, and management information presentation sections 2135a to 2135e. The spatial shape 2133 is an image that represents the shape of the monitoring space 1 of the management target. In Fig. 4, the spatial shape 2133 is represented by the shape of a three-dimensional stereoscopic image. Note that the spatial shape 2133 may also be a two-dimensional planar image.

[0034] The occurrence order marks 2134a to 2134d are displayed superimposed on the spatial shape 2133 and indicate the order in which events occurred within the monitoring space 1. The management information presentation units 2135a to 2135e are displayed superimposed on the spatial shape 2133 and display the location information of the moving object 11, the spatial state within the monitoring space 1, and the operating state of the equipment based on various data acquired from the location measurement tag 111, the environmental measurement sensor 12, the human measurement sensor 13, and the equipment status measurement sensor 14 shown in FIG. 1. The management information presentation units 2135a to 2135e also display the current work content or future work schedule of the equipment, which are calculated based on the equipment work schedule acquired by the equipment status management unit 334 from a server or terminal device external to the control device 3. Note that the management information presentation units 2135a to 2135e may use conspicuous colors such as red or yellow to easily attract the user's attention when displaying management information that particularly deserves attention. Furthermore, the management information presentation units 2135a to 2135e may also display a mark to draw attention to the information.

[0035] 4, for example, a generation order mark 2134a is displayed as a heptagon with the number "1" placed at the center on spatial shape 2133. Adjacent to generation order mark 2134a, management information presentation section 2135a is displayed as a speech bubble containing the message "Switch mode by 1:00 PM" and an "X Complete" button.

[0036] Similarly, generation order mark 2134b is displayed in the shape of a heptagon with the number "2" placed in the center. Adjacent to generation order mark 2134b, management information presentation section 2135b is displayed as a speech bubble containing the message "Possible stoppage around 1:45 PM, wait" and an "X Complete" button.

[0037] Generation order mark 2134c is displayed in the shape of a heptagon with the number "3" placed in the center. Adjacent to generation order mark 2134c, management information presentation section 2135c is displayed as a speech bubble containing the message "Temperature exceeded specified temperature around 2:30 PM, caution regarding temperature management" and an "x Complete" button.

[0038] Furthermore, generation order mark 2134d is displayed in the shape of a heptagon with the number "4" placed in the center. Adjacent to generation order mark 2134d, management information presentation section 2135d is displayed as a speech bubble containing the message "Replace consumable parts on conveyor belt around 4:00 PM" and an "X Complete" button.

[0039] Furthermore, in management information presentation section 2135e, there are no occurrence order marks 2134a to 2134d, and instead a message "Possibility of collision between self-propelled robot C and person A tag notified" and a balloon containing an "x Confirm" button are displayed. This is because emergency content such as that in management information presentation section 2135e needs to be handled with the highest priority, regardless of the order of occurrence.

[0040] Next, the management processing in this embodiment will be described below with reference to the flowcharts shown in Figures 5 to 8. The management processing is stored as a management processing program in the storage unit 32 of the control device 3 shown in Figure 1. The management processing program is started when the control device 3 is started. Specifically, the processor 3304 reads the management processing program stored in the storage device 3302 of the control device 3 shown in Figure 3, loads it into the memory 3303, and executes it.

[0041] The display control unit 335 of the control unit 33 of the control device 3 shown in Fig. 2 displays the spatial shape 2133 of the monitoring space 1 to be managed on the notification screen 211 displayed on the display device 21 of the notification system 2 (step S101). In detail, the display control unit 335 sets the monitoring space 1 selected by the user using the facility selection button 2131a, floor selection button 2131b, or location selection button 2131c in the management location selection unit 2131 of the notification screen 211 shown in Fig. 4 as the monitoring space to be managed, and displays the spatial shape 2133 of the monitoring space 1 on the display device 21 of the notification system 2.

[0042] The equipment status management unit 334 of the control unit 33 of the control device 3 shown in Fig. 2 acquires an equipment work schedule from a server or terminal device external to the control device 3 (step S102). The data acquisition unit 331 of the control unit 33 of the control device 3 acquires various data from the position measurement tags 111, the environment measurement sensors 12, the occupancy measurement sensors 13, and the equipment status measurement sensors 14 in the monitoring space 1 shown in Fig. 1 (step S103).

[0043] The position information management unit 333 of the control unit 33 determines whether the position data of the moving object 11 measured by the position measurement tag 111 shown in Fig. 1 has changed (step S104). If the position data of the moving object 11 has changed (step S104; YES), the position information management unit 333 executes a movement process (step S105). The operation content of the movement process (step S105) will be described below with reference to the flowchart shown in Fig. 6.

[0044] The position information management unit 333 determines whether the number of moving objects 11 whose position data has changed is one (step S201). If the number of moving objects 11 whose position data has changed is one (step S201; YES), the position information management unit 333 calculates a movement path from the position data before and after the movement of the corresponding moving object 11 (step S202).

[0045] The position information management unit 333 determines whether the position data of the moving object 11 measured by the position measurement tag 111 is the same as the position data of another moving object 11 (step S203). If the position data is different from the position data of another moving object 11 (step S203; NO), the position information management unit 333 determines that the moving object 11 is not in contact with the other moving object 11. The position information management unit 333 updates the position data of the moving object 11 to the position data after movement (step S204).

[0046] Also, if the position data is the same as that of another moving object 11 (step S203; YES), the position information management unit 333 notifies the position measurement tags 111 of the moving object 11 and the other moving object 11 that they have come into contact (step S205).

[0047] The position information management unit 333 creates a warning message (step S206). For example, the position information management unit 333 creates a message such as "Possibility of collision between self-propelled robot C and person A has been notified by tag," as in the management information presentation unit 2135e shown in Fig. 4. The position information management unit 333 updates the position data of the moving object 11 to the position data after the movement (step S204).

[0048] Furthermore, in step S201, if there are multiple moving objects 11 whose position data has changed (step S201; NO), the position information management unit 333 calculates the movement path for each of the multiple corresponding moving objects 11 from the position data before and after the movement (step S207). The position information management unit 333 determines whether the position data of the moving object 11 measured by the position measurement tag 111 is the same as the position data of another moving object 11 or the position data of another moving object 11 after the movement (step S208).

[0049] If the position data differs from the position data of the other moving objects 11 or the position data of the other moving objects 11 after movement (step S208; NO), the position information management unit 333 determines that the moving object 11 is not in contact with the other moving objects 11. The position information management unit 333 updates the position data of the moving object 11 to the position data after movement (step S209).

[0050] Also, in step S208, if the position data is the same as that of another moving object 11 or the position data of another moving object 11 after it has moved (step S208; YES), the position information management unit 333 notifies the position measurement tags 111 of the moving object 11 and the other moving object 11 that they have come into contact (step S210).

[0051] The position information management unit 333 creates a warning message (step S211). The position information management unit 333 updates the position data of the moving object 11 to the position data after the movement (step S209). The position information management unit 333 ends the movement process.

[0052] Returning to Fig. 5, the display control unit 335 of the control unit 33 of the control device 3 shown in Fig. 2 updates the display content of the notification screen 211 displayed on the display device 21 of the notification system 2 (step S106). For example, the display control unit 335 displays the warning message created in step S206 or step S211 of Fig. 6, superimposed on the spatial shape 2133 of the monitoring space 1 of the management target, displayed on the notification screen 211. Returning to step S103, the data acquisition unit 331 of the control unit 33 of the control device 3 executes step S103 and subsequent steps.

[0053] Furthermore, in step S104, if the position data of the moving object 11 measured by the position measurement tag 111 shown in Fig. 1 has not changed (step S104; NO), the equipment status management unit 334 of the control unit 33 of the control device 3 shown in Fig. 2 determines whether the equipment status in the monitoring space 1 has changed (step S107). If the equipment status has changed (step S107; YES), the equipment status management unit 334 executes equipment status change processing (step S108). The equipment status change processing (step S108) will be described below with reference to the flowchart shown in Fig. 7.

[0054] The device status management unit 334 calculates the device status from various data acquired from the device status measurement sensor 14 in step S103 of Fig. 5. The device status management unit 334 determines the current work content of the device based on the calculated device status (step S301). In detail, the device status management unit 334 compares the device work schedule acquired from a server or terminal device external to the control device 3 in step S102 of Fig. 5 with the calculated device status to determine the current work content of the device.

[0055] The appliance status management unit 334 determines future appliance work content based on the appliance status calculated in step S301 and the appliance work schedule (step S302). Specifically, the appliance status management unit 334 determines the appliance work content after a certain time, for example, one hour, starting from the current appliance work content calculated from the calculated appliance status and the appliance work schedule.

[0056] The device status management unit 334 determines whether the future device work content will change from the current work content (step S303). If the work content will change (step S303; YES), the device status management unit 334 calculates the time when the work content will change based on the current time and the device work schedule (step S304). The device status management unit 334 creates a message indicating that the work content will change (step S305). For example, the device status management unit 334 creates a message such as "Switch mode by 1:00 PM" like the management information presentation unit 2135a shown in FIG. 4.

[0057] Furthermore, if the future work content of the device remains the same as the current work content in step S303 (step S303; NO), the device status management unit 334 determines whether the device is scheduled to be shut down (step S306). If the device is scheduled to be shut down (step S306; YES), the device status management unit 334 creates a message to that effect (step S307). For example, the device status management unit 334 creates a message such as "Possible shutdown around 1:45 PM, wait," as in the management information presentation unit 2135b shown in FIG. 4.

[0058] If the device is not scheduled to be shut down (step S306; NO), the device status management unit 334 updates the device status based on the device status calculated in step S301 (step S308).The device status management unit 334 determines whether the expiration date of the device parts is approaching (step S309).

[0059] If the expiration date of the device part is approaching (step S309; ​​YES), the device status management unit 334 creates a message indicating that the part should be replaced (step S310). For example, the device status management unit 334 creates a message such as "Replace consumables on the belt conveyor around 4:00 PM" as in the management information presentation unit 2135d shown in FIG. 4. If the expiration date of the device part is not approaching (step S309; ​​NO), the device status management unit 334 ends the device status change process.

[0060] Returning to Fig. 5, the display control unit 335 of the control unit 33 of the control device 3 shown in Fig. 2 updates the display content of the notification screen 211 displayed on the display device 21 of the notification system 2 (step S106). For example, the display control unit 335 displays a message indicating that the work content will be switched, created in step S305 of Fig. 7, a message indicating that the work will be stopped, created in step S307, or a message indicating that a part will be replaced, created in step S310, superimposed on the spatial shape 2133 of the monitoring space 1 of the management target, displayed on the notification screen 211. Returning to step S103, the data acquisition unit 331 of the control unit 33 of the control device 3 executes step S103 and subsequent steps.

[0061] Furthermore, if the device state in the monitoring space 1 has not changed in step S107 (step S107; NO), the space state calculation unit 332 of the control unit 33 shown in Fig. 2 calculates the space state in the monitoring space 1 based on the various data acquired from the environment measurement sensor 12 in step S103 (step S109). The space state calculation unit 332 determines whether the calculated space state has changed from the space state before calculation (step S110).

[0062] If the calculated spatial state has not changed from the spatial state before the calculation (step S110; NO), the process returns to step S103, and the data acquisition unit 331 of the control unit 33 of the control device 3 executes step S103 and subsequent steps. If the calculated spatial state has changed from the spatial state before the calculation (step S110; YES), the spatial state calculation unit 332 executes a spatial state determination process (step S111). The spatial state determination process (step S111) will be described below with reference to the flowchart shown in FIG. 8 .

[0063] The space condition calculation unit 332 determines whether the calculated space condition exceeds a specified value (step S401). For example, assume that the temperature in the space measured by the temperature sensor 122 of the environment measurement sensor 12 shown in FIG. 1 exceeds a specified temperature value. In this case, since the calculated space condition exceeds the specified value (step S401; YES), the space condition calculation unit 332 creates a message indicating that the space condition exceeds the specified value (step S402). For example, the equipment status management unit 334 creates a message such as "Temperature exceeded specified temperature around 2:30 p.m., caution regarding temperature management," as in the management information presentation unit 2135c shown in FIG. 4.

[0064] The space state calculation unit 332 updates the space state data with the calculated space state data (step S403). Also, in step S401, for example, it is assumed that the temperature in the space measured by the temperature sensor 122 of the environment measurement sensor 12 shown in FIG. 1 does not exceed a specified temperature value. In this case, since the calculated space state does not exceed the specified value (step S401; NO), the space state calculation unit 332 updates the space state data with the calculated space state data (step S403). The space state calculation unit 332 ends the space state change process.

[0065] Returning to Fig. 5, the display control unit 335 of the control unit 33 of the control device 3 shown in Fig. 2 updates the display content of the notification screen 211 displayed on the display device 21 of the notification system 2 (step S106). For example, the display control unit 335 displays a message indicating that the space state created in step S402 of Fig. 8 exceeds a specified value, superimposed on the space shape 2133 of the monitoring space 1 of the management target displayed on the notification screen 211. Returning to step S103, the data acquisition unit 331 of the control unit 33 of the control device 3 executes step S103 and subsequent steps.

[0066] As described above, the management system 100 according to this embodiment can grasp events other than work in the indoor monitoring space 1, such as the spatial condition of the work area and the presence or absence of people.

[0067] (Variant Example) In the above-described embodiment, a factory production site was used as an example of the monitored space 1, but the monitored space 1 is not limited to this and can be any space where a large number of people and objects enter and exit, such as a hospital floor, a theater, a movie theater, a hall, a department store, a shopping mall, or other commercial facility.

[0068] In the above embodiment, the control device 3 is a server that functions as a cloud, but the present invention is not limited to this and may be a stand-alone computer.

[0069] Furthermore, in the above-described embodiment, the spatial state change process of Figure 8 was explained using temperature as an example of the spatial state, but this is not limited to this. The change in the spatial state may also be determined based on at least one or more of the carbon dioxide concentration, humidity, air pressure, and amount of particulate matter acquired by each sensor included in the environmental measurement sensor 12.

[0070] In addition, in the above-described embodiment, a two-dimensional code may be prepared as a work content management means that can manage work content and work processes on a slip-by-slip basis, and by reading the two-dimensional code with a reading means such as a barcode reader or scanner, it may be possible to manage current work content and work processes as well as future work content and work processes.

[0071] In the above embodiment, the moving object 11 is an object that moves within the monitoring space 1, and includes the user tool 11a and the mechanical tool 11b. However, the moving object 11 may also include transported goods, parts, work-in-progress, and finished products that move within the monitoring space 1.

[0072] Furthermore, in the above-described embodiment, the description has been given including a function of notifying the location tag 111 of proximity information, etc., but it is also possible to operate in a configuration that does not have a function of notifying the location tag 111 of proximity information, etc. In this case, for example, the location tag 111 is used to acquire location information, and notification to the user is performed by a message or an alert sound displayed on the notification system 2, or by an alarm device 15 such as a speaker or rotating light installed in the monitoring space 1.

[0073] The program in this embodiment may be applied in any manner. For example, the program may be stored on a computer-readable storage medium such as a flexible disk, a CD (Compact Disc)-ROM, a DVD (Digital Versatile Disc)-ROM, or a memory card. Furthermore, the program may be superimposed on a carrier wave and applied via a communication medium such as the Internet. For example, the program may be posted and distributed on a bulletin board system (BBS) on a communication network. The display selection processing program may then be started and executed under the control of an operating system (OS) in the same way as other application programs, thereby enabling the above processing to be performed.

[0074] The present invention allows various embodiments and modifications without departing from the broad spirit and scope of the present invention. Furthermore, the above-described embodiments are intended to explain the present invention and do not limit the scope of the present invention. That is, the scope of the present invention is defined by the claims, not the embodiments. Various modifications made within the scope of the claims and within the scope of the meaning of the invention equivalent thereto are considered to be within the scope of the present invention.

[0075] This application is based on Japanese Patent Application No. 2024-124516, filed on July 31, 2024. The entire specification, claims, and drawings of Japanese Patent Application No. 2024-124516 are incorporated herein by reference.

[0076] As described above, according to the present invention, it is possible to provide a management system that is capable of grasping events other than work, such as the spatial condition of the work area and the presence or absence of people, in an indoor monitoring space.
