[0011] Hereinafter, embodiments of the present invention will be described in detail. For the sake of convenience, the same reference numerals will be used to designate components having the same functions as those in the embodiments, and the description thereof will be omitted where appropriate.

[0012] [Embodiment 1] An embodiment of the present invention will be described with reference to FIGS.

[0013] (Maintenance work support system) 1 is a block diagram showing an overview of a maintenance work support system according to this embodiment. The maintenance work support system 1 of this embodiment supports maintenance work in various facilities PL, such as office buildings, factories, and commercial facilities. The maintenance work includes various maintenance methods according to the various maintenance targets MO in the facility, such as cleaning floors, toilets, stairs, handrails, etc., collecting trash from trash cans, changing toilet paper, wiping windows, mowing the lawn, tidying rooms, and inspecting and maintaining various pieces of equipment.

[0014] As shown in Figure 1, the maintenance work support system 1 is configured to include a maintenance work support device 2, a sensor 3, an inspection terminal 4, an implementation request terminal 5 (information terminal), and a work robot 6b. The maintenance work support device 2 creates a maintenance plan for each maintenance target MO based on various data acquired from the maintenance target MO via the sensor 3, the inspection terminal 4, and the implementation request terminal 5, and instructs the work staff 6 to perform maintenance work based on the maintenance plan. As a result, the work staff 6 moves to the maintenance target MO and performs the maintenance work during the time period specified in the maintenance plan.

[0015] The maintenance work support device 2, the sensor 3, the inspection terminal 4, and the implementation request terminal 5 are communicably connected via a communication network (not shown) such as the Internet. The work staff 6 include a worker 6a and a self-propelled work robot 6b that performs the maintenance work, and the maintenance work support device 2, the terminal of the worker 6a, and the work robot 6b are communicably connected via a communication network (not shown) such as the Internet. Depending on the type of maintenance, the work robot 6b may be a vacuum robot, a scrubber robot, a toilet cleaning robot, a stair cleaning robot, a window cleaning robot, a lawn mowing robot, or the like.

[0016] The sensor 3 senses the condition of the maintenance target MO. Typical examples of the sensor 3 include a dust sensor, a water ingress sensor, and an odor sensor. The sensor 3 transmits sensor data obtained by the above sensing to the maintenance work support device 2. The sensor 3 may be a sensor provided on the work robot 6b, or may be a sensor installed near the maintenance target MO. The sensor 3 may also be a camera, in which case the sensor data may be image data obtained by photographing the condition of the maintenance target MO with the camera.

[0017] Furthermore, the sensor 3 includes a people flow sensor that detects the flow of people at the location where the maintenance object MO is located and a people count sensor that counts the number of people. Note that instead of the people flow sensor or people count sensor, a camera may be provided, and the maintenance work support device 2 may process images from the camera to detect the flow of people or the number of people.

[0018] The inspection terminal 4 inspects the degree of contamination of the MO to be maintained and transmits the inspection result data obtained to the maintenance work support device 2. The above inspection may be a wipe inspection. The above wipe inspection may be an ATP wipe inspection in which the amount of ATP (adenosine triphosphate) is quantified.

[0019] The swab test may be a test that quantifies the amount of at least one of ATP, ADP (adenosine diphosphate), and AMP (adenosine monophosphate), or the total amount of at least two of them. The swab test may be a test that quantifies the number of microorganisms. The swab test may be a test that counts the number of microparticles in the space of the MO to be maintained using a particle counter. The swab test may be performed by a person or by a work robot 6b.

[0020] The implementation request terminal 5 accepts an operation requesting maintenance of the MO to be maintained. Upon accepting the operation, the implementation request terminal 5 transmits a request to perform maintenance on the MO to be maintained to the maintenance work support device 2. The implementation request terminal 5 may be a fixed terminal installed near the MO to be maintained, or may be a mobile terminal such as a smartphone. In the case of a mobile terminal, the operation may be accepted by the mobile terminal reading an information code (for example, a two-dimensional code such as a QR code (registered trademark)) installed near the MO to be maintained. Alternatively, the operation may be accepted by a dedicated application executed on the implementation request terminal 5.

[0021] (Maintenance work support device) 2 is a block diagram showing a schematic configuration of the maintenance work support device 2. As shown in FIG. 2, the maintenance work support device 2 includes a control unit 10, a storage unit 11, and a communication unit 12.

[0022] The control unit 10 comprehensively controls the operation of various components of the maintenance work support device 2, and is configured by, for example, a computer including a CPU (Central Processing Unit) and a memory. The operation of the various components is controlled by causing the computer to execute a control program. The control unit 10 will be described in detail later.

[0023] The memory unit 11 records information and is composed of a storage device such as a hard disk or flash memory. The communication unit 12 transmits and receives information to and from the sensor 3, the inspection terminal 4, the implementation request terminal 5, and the work staff 6 (the terminal of the worker 6a and the work robot 6b) via a communication network (not shown). The communication unit 12 is equipped with communication devices such as a transmission / reception circuit.

[0024] In this embodiment, the control unit 10 includes a necessity degree acquisition unit 20 (acquisition unit), a statistical information acquisition unit 21 (acquisition unit), a determination unit 22, a map creation unit 23 (creation unit), an area setting unit 24 (setting unit), a maintenance planning unit 25 (planning unit), and a maintenance instruction unit 26 (instruction unit). The storage unit 11 stores a necessity degree DB (database) 30, priority area data 31, and a maintenance plan DB 32.

[0025] The necessity obtaining unit 20 obtains the degree of necessity of maintenance for the maintenance target MO by using various data from the sensor 3, the inspection terminal 4, and the implementation request terminal 5. The necessity obtaining unit 20 stores the degree of necessity of maintenance in the necessity DB 30 of the storage unit 11 together with the location information of the maintenance target MO and the date and time when the degree of necessity was obtained.

[0026] The maintenance necessity level indicates the degree to which maintenance is required. The necessity level may be expressed, for example, on a scale of 1 to 100. In this case, 0 may be assigned to cases where no maintenance is required, and 100 may be assigned to cases where maintenance is absolutely required. The maintenance necessity level includes the degree of dirtiness of floors, toilets, stairs, handrails, etc., the degree of garbage accumulation in trash cans, the degree of toilet paper depletion, the degree of liquid hand soap depletion, etc.

[0027] For example, the degree of contamination may be obtained based on the test result data of the ATP wipe test on the maintenance object MO. The degree of contamination may also be obtained based on the results of comparing a current image captured by a camera serving as sensor 3 with a past image. The degree of contamination may also be obtained based on sensor data from a dust sensor installed on the work robot 6b that performs the cleaning work. For example, the degree of dust accumulation may be obtained based on sensor data from a level sensor serving as sensor 3 installed on the trash can. The degree of toilet paper reduction may also be obtained based on sensor data from a level sensor serving as sensor 3 installed on the toilet paper. The degree of hand-washing liquid soap reduction may also be obtained based on sensor data from a level sensor serving as sensor 3 installed on the liquid soap container.

[0028] The necessity obtaining unit 20 may further obtain people flow information indicating the flow of people at the location where the maintenance target MO is located. The people flow information may be any information that can grasp the degree of congestion at the location, such as the occupancy rate of toilets or the number of users.

[0029] The statistical information acquisition unit 21 acquires statistical information for a predetermined period (for example, one month) regarding the degree of necessity of maintenance for each maintenance target MO by referring to the necessity DB 30 in the storage unit 11. The statistical information acquisition unit 21 sends the statistical information to the determination unit 22.

[0030] Specifically, the above statistical information is at least one of the following statistical information: sensor data obtained from a sensor 3 that senses the condition of the MO to be maintained; inspection result data obtained from an inspection terminal 4 by inspecting the degree of dirtiness of the MO to be maintained; people flow at the location where the MO to be maintained is located; and a request to perform maintenance on the MO to be maintained obtained from an implementation request terminal 5.

[0031] The determination unit 22 determines whether the degree of necessity is higher than a predetermined threshold for each maintenance target MO based on the statistical information from the statistical information acquisition unit 21. The determination unit 22 sends the determination result to the map creation unit 23 and the area setting unit 24.

[0032] The map creation unit 23 creates a heat map based on the determination result from the determination unit 22. The heat map is a layout of each maintenance target MO on a map of the facility PL, and visualizes the maintenance target MOs determined by the determination unit 22 to have a degree of necessity higher than a predetermined threshold. The map creation unit 23 transmits the created heat map to a terminal (not shown) of a maintenance work manager via the communication unit 12. The manager can easily identify the locations requiring maintenance by referring to the heat map.

[0033] Fig. 3 is a diagram showing an example of the heat map. In the heat map HM shown in Fig. 3, the flow of people in areas where the congestion level (0 to 100) measured by the people flow sensor exceeds 80 is shown by a dashed line. Furthermore, during regular cleaning, floor locations where the floor dirtiness level (0 to 100) detected by the dust sensor of the work robot 6b exceeds 90 are shown by white circles. Furthermore, among maintenance target MOs other than floors, maintenance target MOs where the dirtiness level measured by regular ATP wipe inspection exceeds 90 are shown by black circles.

[0034] In this embodiment, the facility PL is divided into a plurality of areas AR as shown in Fig. 1. The area of ​​each area AR is, for example, 10 m 2 is.

[0035] The area setting unit 24 sets, as a priority area PA, an area AR in which a predetermined number or more of maintenance targets MO whose necessity level is determined to be higher than the predetermined threshold exist, based on the determination result from the determination unit 22. The area setting unit 24 stores information about the set priority area PA in priority area data 31 in the storage unit 11.

[0036] For example, if the statistical information for the predetermined period shows that there are five or more maintenance target MOs in the area AR with a contamination level of 90 or higher, the area setting unit 24 sets the area AR as a priority area PA. Also, as another example, if the statistical information for the predetermined period shows that there are five or more maintenance target MOs in the area AR with a congestion level of 90 or higher, the area setting unit 24 sets the area AR as a priority area PA. Also, as another example, if the statistical information for the predetermined period shows that three or more execution requests have been received from the execution request terminal 5 for the maintenance target MOs in the area AR, the area setting unit 24 sets the area AR as a priority area PA.

[0037] Figure 4 is a diagram visualizing the priority areas PA on the map of the facility PL.

[0038] The maintenance planning unit 25 references the necessity DB 30 in the memory unit 11 and creates a maintenance plan for each maintenance target MO. Specifically, the maintenance planning unit 25 determines whether to assign the work to a worker 6a or a work robot 6b, and if a work robot 6b is to be assigned to perform the work, what type of work robot 6b to assign, depending on the type of maintenance necessity in the necessity DB 30, and creates the maintenance plan based on the results of this determination. The maintenance planning unit 25 stores the created maintenance plan in the maintenance plan DB 32 in the memory unit 11. The maintenance instruction unit 26 references the maintenance plan DB 32 in the memory unit 11 and instructs the terminal of the worker 6a and the work robot 6b to perform maintenance work via the communication unit 12.

[0039] In this embodiment, the maintenance planning unit 25 refers to the priority area data 31 in the memory unit 11 and creates a maintenance plan for at least one of the travel route of the self-propelled work robot 6b that will perform the maintenance work and the content of the maintenance work to be performed by the work robot 6b, so as to reduce the necessity of the maintenance targets MO included in the priority area PA.

[0040] For example, the maintenance planner 25 may plan the travel route so that the work robot 6b travels through the priority area PA multiple times. At this time, the maintenance instructor 26 may refer to the people flow information from the necessity level acquirer 20 and the priority area data 31 in the memory unit 11, and instruct the work robot 6b to travel through the priority area PA multiple times along the travel route only during time periods when the level of people flow in the priority area PA is below a predetermined standard value (e.g., late at night, early morning, etc.). The maintenance instructor 26 may also set in advance time periods when work by the work robot 6b is prohibited (e.g., daytime working hours in an exclusive area), and instruct the work robot 6b to travel through the priority area PA multiple times along the travel route during time periods other than those work hours. In this case, the possibility of a collision between the work robot 6b and a person can be reduced.

[0041] Furthermore, the maintenance planning unit 25 may plan the above-mentioned implementation details so that the work robot 6b performs maintenance work in the priority area PA more intensively (concentratedly) than standard maintenance work. Specifically, the maintenance planning unit 25 may plan the above-mentioned implementation details so that the work robot 6b performs maintenance work in the priority area PA with improved maintenance performance compared to standard maintenance work.

[0042] Examples of the above-mentioned improvement in maintenance performance include increasing the cleaning power of the work robot 6b performing cleaning work compared to standard maintenance work, or adding scrubbing work to standard vacuuming work, etc. At this time, the maintenance instructing unit 26 may refer to the people flow information from the necessity obtaining unit 20 and the priority area data 31 in the memory unit 11, and if the degree of people flow in the priority area PA is equal to or less than a predetermined reference value, instruct the work robot 6b to perform the maintenance work in the priority area PA in accordance with the above-mentioned planned implementation content.

[0043] For example, when improving the maintenance performance of the work robot 6b compared to standard maintenance work, the noise of the work robot 6b may become louder. In this case, as the level of people flowing in the priority area PA increases, more people will hear the noise and become uncomfortable with it. In contrast, with the above configuration, because the level of people flowing is below a predetermined standard value, fewer people will hear the noise and become uncomfortable with it.

[0044] Furthermore, the maintenance planning unit 25 may plan the travel route so that the work robot 6b with relatively high maintenance capability passes through the priority area PA. An example of a work robot 6b with relatively high maintenance capability is a vacuum robot with relatively high suction capability.

[0045] According to the above configuration, at least one of the travel route of the self-propelled work robot 6b that will perform the maintenance work and the content of the maintenance work to be performed by the work robot 6b is planned so as to reduce the degree of maintenance necessity for maintenance targets MO included in a priority area PA that contains a predetermined number or more of maintenance targets MO whose degree of maintenance necessity is determined to be higher than a predetermined threshold. By having the work robot 6b perform maintenance work according to this plan, the degree of maintenance necessity for maintenance targets MO included in the priority area PA can be reduced. In other words, maintenance work in the priority area PA can be appropriately performed using the work robot 6b.

[0046] (Maintenance work support processing) Fig. 5 is a flowchart showing the flow of the maintenance work support process in the maintenance work support device 2 of this embodiment. As shown in Fig. 5, first, the necessity degree acquisition unit 20 collects the degree of necessity of maintenance for the maintenance target MO using various data from the sensor 3, the inspection terminal 4, and the implementation request terminal 5, and stores the degree of necessity of maintenance in the necessity degree DB 30 of the storage unit 11 together with the location information of the maintenance target MO and the acquisition date and time of the degree of necessity (S10).

[0047] Next, the statistical information acquisition unit 21 refers to the necessity DB 30 in the storage unit 11 and acquires statistical information for a predetermined period regarding the degree of necessity of maintenance for each maintenance target MO (S11, acquisition step). Next, the determination unit 22 determines whether the degree of necessity for each maintenance target MO is higher than a predetermined threshold based on the statistical information from the statistical information acquisition unit 21 (S12, determination step). Next, the map creation unit 23 creates a heat map based on the determination result of the determination unit 22 (S13). Note that step S13 may be omitted.

[0048] Next, based on the judgment result of the judgment unit 22, the area setting unit 24 sets the area AR where there are a predetermined number or more maintenance targets MO whose necessity level is determined to be higher than the predetermined threshold as a priority area PA, and stores this in the priority area data of the memory unit 11 (S14, setting step). Next, the maintenance planning unit 25 references the necessity DB 30 in the memory unit 11 to create a maintenance plan for each maintenance target MO, and further creates a maintenance plan for at least one of the travel route of the self-propelled work robot 6b that will perform the maintenance work and the details of the maintenance work to be performed by the work robot 6b, so as to reduce the necessity of the maintenance targets MO included in the priority area PA (S15, planning step). Then, the maintenance instruction unit 26 references the maintenance plan and instructs the terminal of the worker 6a and the work robot 6b to perform the maintenance work (S16). Thereafter, the maintenance work support process ends.

[0049] [Embodiment 2] Another embodiment of the present invention will now be described with reference to FIGS.

[0050] The maintenance work support system 1 of the first embodiment performs maintenance work intensively in a priority area PA. However, due to subsequent changes in the layout of the facility, changes in the environment, etc., it may become unnecessary to perform maintenance work intensively in the priority area PA. In this case, performing maintenance work intensively in the priority area PA is excessive work and is wasteful.

[0051] Therefore, the maintenance work support system 1 of this embodiment cancels the setting of the priority area PA for which it is no longer necessary to perform priority maintenance work, thereby making it possible to prevent unnecessary maintenance work.

[0052] Fig. 6 is a block diagram showing a schematic configuration of the maintenance work support device 2 in the maintenance work support system 1 according to this embodiment. The maintenance work support device 2 of this embodiment differs from the maintenance work support device 2 shown in Fig. 2 in that a determination unit 40 and an area setting unit 41 (setting unit) are provided instead of the determination unit 22 and the area setting unit 24, but the other configurations are the same.

[0053] The determination unit 40 performs the same operation as the determination unit 22 shown in Fig. 2. Furthermore, the determination unit 40 determines whether the degree of necessity of each of the maintenance targets MO included in the priority area PA remains below a predetermined value for a predetermined period of time, using the statistical information from the statistical information acquisition unit 21 and the priority area data 31 in the storage unit 11. The determination unit 40 sends this determination result to the area setting unit 41.

[0054] The area setting unit 41 operates in the same manner as the area setting unit 24 shown in Fig. 2. Furthermore, if the degree of necessity (degree of dirt, degree of congestion, etc.) of each of the maintenance targets MO included in the priority area PA falls below a predetermined value for a predetermined period based on the determination result from the determination unit 40, the area setting unit 41 cancels the setting of the priority area PA and updates the priority area data 31 in the storage unit 11. This makes it possible to prevent waste in maintenance work.

[0055] 7 is a flowchart showing the flow of the process of canceling the setting of the priority area PA in the maintenance work support device 2 of this embodiment. The setting cancellation process is executed between step S11 and step S15 in the maintenance work support process shown in FIG.

[0056] 7, first, the determination unit 40 uses statistical information and priority area data to determine whether the degree of necessity of each maintenance target MO included in the priority area PA is below a predetermined value over a predetermined period of time (S20). Next, based on the determination result, if the degree of necessity of each maintenance target MO included in the priority area PA is below a predetermined value over a predetermined period of time, the area setting unit 41 cancels the setting of the priority area PA and updates the priority area data 31 in the storage unit 11 (S21). Thereafter, the setting cancellation process ends.

[0057] (Additional notes) Some of the processes executed by the maintenance work support device 2 may be executed by another information processing device (computer). In other words, the entity that executes each process described in each of the above embodiments can be changed as appropriate, and the maintenance work support system 1 according to the present invention can be realized with various system configurations. For example, each of the processes shown in FIGS. 5 and 7 may be executed by sharing the work among multiple information processing devices (computers).

[0058] [Software implementation example] The functions of the maintenance work support device 2 (hereinafter referred to as the "device") can be realized by a program that causes a computer to function as the device, and a program that causes a computer to function as each control block of the device (particularly each part included in the control unit 10).

[0059] In this case, the device includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing the program. The control device and storage device execute the program, thereby realizing the functions described in each of the above embodiments.

[0060] The program may be non-transitory and may be recorded on one or more computer-readable recording media. The recording media may or may not be included in the device. In the latter case, the program may be supplied to the device via any wired or wireless transmission medium.

[0061] Furthermore, some or all of the functions of the control blocks can be realized by logic circuits. For example, an integrated circuit in which a logic circuit that functions as each of the control blocks is formed is also included in the scope of the present invention. In addition, the functions of the control blocks can also be realized by, for example, a quantum computer.

[0062] Furthermore, each process described in each of the above embodiments may be executed by AI (Artificial Intelligence). In this case, the AI ​​may run on the control device or on another device (for example, an edge computer or a cloud server).

[0063] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
