[0014] The user tool 11a and the mechanical tool 11b are respectively provided with a position measurement tag 111a and a position measurement tag 111b, which are position measurement means for measuring a position in space. Note that hereinafter, the position measurement tag 111a and the position measurement tag 111b are collectively referred to as the position measurement tag 111. The position measurement tag 111 can be, for example, an RFID (Radio Frequency Identification) tag whose position is determined by being read by radio waves emitted from a reader or by having the radio waves emitted by the tag read by a reader, or an UWB (Ultra Wide Band) tag whose position is determined by the time it takes for the radio waves emitted from the tag to reach a receiver.

[0015] The environmental measurement sensor 12 is an environmental measurement means that measures the gaseous environment in the monitoring space 1 and acquires data on the gaseous environment. The environmental measurement sensor 12 includes a CO2 sensor 121, a temperature sensor 122, a humidity sensor 123, an air pressure sensor 124, and a particulate sensor 125. The CO2 sensor 121 measures the concentration of carbon dioxide contained in the atmosphere in the space. The temperature sensor 122 measures the temperature in the space. The humidity sensor 123 measures the humidity contained in the atmosphere in the space. The air pressure sensor 124 measures the air pressure in the space. The particulate sensor 125 measures the amount of particulates contained in the atmosphere in the space.

[0016] The human measurement sensor 13 is a human measurement means for measuring the number and positions of people present in a space and acquiring human data. The human measurement sensor 13 may be, for example, a camera capable of detecting people from still images and video information captured in a space, or a LiDAR (Light Detection and Ranging) device that detects the distance to an object and its shape based on information on the reflected light of an irradiated laser beam.

[0017] The equipment status measurement sensor 14 is an equipment status measurement means that measures operational data of equipment such as manufacturing equipment for manufacturing products arranged in a space, and transport equipment such as a belt conveyor that transports products between the manufacturing equipment. The equipment status measurement sensor 14 includes an operation status sensor 141, a power sensor 142, a vibration sensor 143, an open / close sensor 144, a water flow sensor 145, a pH sensor 146, and an air volume sensor 147. The operation status sensor 141 measures various states of the equipment, such as whether it is operating, stopped, or an abnormality has occurred.

[0018] The power sensor 142 measures the power status of the equipment. The vibration sensor 143 measures vibrations when the equipment is operating. The open / close sensor 144 measures the open / close state of the equipment's door. The water flow sensor 145 measures the amount of water used inside the equipment for washing products, dissipating heat, etc. The pH sensor 146 measures the hydrogen ion exponent of the aqueous solution used in the production of products inside the equipment. The air volume sensor 147 measures the amount of air used inside the equipment to produce products, for example, to blow away dust or cool products.

[0019] The notification device 15 is a notification means for notifying the user of the operating state of the equipment and the spatial state within the space, and may be, for example, a speaker, a rotating light, or the like.

[0020] The notification system 2 is a system for notifying a user of the current environmental state within a space, and includes a display device 21 as a display means. The display device 21 displays the current environmental state within the space. The notification system 2 can be configured using a small portable device such as a tablet or smartphone. The notification system 2 may also include a speaker for outputting alert sounds, voices, etc.

[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 human 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, 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, as shown in FIG.

[0024] The data acquisition unit 331 acquires various data from the position measurement tags 111, the environment measurement sensors 12, the human 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 human data measured by the human 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 environment 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 LAN (Local Area Network). 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 environment 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 an HDD (Hard Disk Drive) or an SSD (Solid State Drive).

[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 RAM (Random Access Memory) 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 CPU (Central Processing Unit) or an MPU (Micro-Processing Unit).

[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 month / XX day (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, occurrence 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-2134d are displayed superimposed on the spatial shape 2133 and indicate the order of events that occurred in the monitoring space 1. The management information presentation units 2135a-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-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. When displaying management information that particularly deserves attention, the management information presentation units 2135a-2135e may use a conspicuous color such as red or yellow to easily attract the user's attention. Furthermore, the management information presenting 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 in the center on the spatial shape 2133. Adjacent to the generation order mark 2134a, a management information presentation section 2135a is displayed as a speech bubble containing the message "Switch modes 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 "× Complete" button.

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

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

[0039] Furthermore, in the 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 notification has been sent" and a balloon containing an "x Confirm" button are displayed. This is because emergency content such as that in the 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] 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, and location selection button 2131c in the management location selection section 2131 of the notification screen 211 shown in FIG. 4 as the monitoring space 1 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] 2 acquires a work schedule for the equipment from a server or a terminal device external to the control device 3 (step S102). The data acquisition unit 331 of the control device 3 acquires various data from the position measurement tag 111, the environment measurement sensor 12, the human measurement sensor 13, and the equipment status measurement sensor 14 in the monitoring space 1 shown in FIG. 1 (step S103).

[0043] The position information management unit 333 of the control unit 33 of the control device 3 determines whether or not 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 route 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. Tag notification has been sent," 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 a movement route 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 object 11 or the position data of the other moving object 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 object 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, which is 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 device status management unit 334 determines future device work content based on the device status calculated in step S301 and the device work schedule (step S302). In detail, the device status management unit 334 determines the device work content after a certain time, for example, one hour, starting from the current device work content calculated from the calculated device status and device work schedule.

[0056] The device status management unit 334 determines whether the future work content of the device 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 from the current time and the work schedule of the device (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" as in the management information presentation unit 2135a shown in FIG. 4.

[0057] Furthermore, in step S303, if the future work content of the device remains the same as the current work content (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 to the effect 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 p.m.", 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, superimposed on the spatial shape 2133 of the monitoring space 1 of the management target displayed on the notification screen 211, 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 parts will be replaced, created in step S310. 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, in step S107, if the device state in the monitoring space 1 has not changed (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 thereafter. 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 state calculation unit 332 determines whether the calculated space state 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 state exceeds the specified value (step S401; YES), the space state calculation unit 332 creates a message indicating that the space state exceeds the specified value (step S402). For example, the device state 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] (Variation) In the above-described embodiment, a factory production site has been 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 many people and things 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] Furthermore, in the above-described 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 thereto. 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-described 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 proximity information, etc. to the location tag 111, but it is also possible to operate in a configuration that does not have a function of notifying proximity information, etc. to the location tag 111. 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 a rotating light installed in the monitoring space 1.

[0073] Furthermore, the method of applying the program in this embodiment is arbitrary. For example, the program can be stored in 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 and applied. Furthermore, the program can be superimposed on a carrier wave and applied via a communication medium such as the Internet. For example, the program can be posted and distributed on a bulletin board system (BBS) on a communication network. Then, the display selection processing program can 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] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to such specific embodiments, and the present invention includes the inventions described in the claims and their equivalents. [Explanation of symbols]
