Description

Technical Field

[0001] The disclosed embodiments relate to a toilet cleaning plan management system.

Background Art

[0002] Among industries, the cleaning industry has been in the most serious situation due to the decrease in the labor force. Among them, toilet cleaning is an urgent issue as the average age of workers exceeds 50 years old, and the reduction and simplification of the workload are crucial. On the other hand, the toilet space is not noticeable to people and allows for privacy. It is often used for purposes other than excretion (personal grooming, relaxation), so the cleaning requirements are increasing, and conversely, the cleaning load and cost are rising.

[0003] Currently, toilet operations set the frequency and items based on the assumed number of personnel using the facility. Therefore, when the number of present personnel is less (than expected) or workers do not attend the facility due to telecommuting or using a shared office, the dirt in the toilet space decreases, and unnecessary cleaning is being done. Therefore, if a cleaning plan can be made according to the actual situation of toilet use, it can contribute to reducing the burden of cleaning work.

[0004] Under such circumstances, a toilet management system has been disclosed that sets a larger number of cleaning items, a larger cleaning range, and a higher cleaning frequency for toilet rooms with a high usage frequency than for toilets with a low usage frequency.

[0017] In a toilet cleaning plan management system according to one embodiment, the system further comprises a cleaning item setting means for setting the plurality of cleaning items, and the cleaning plan creation means modifies the cleaning plan to a second cleaning plan based on the modified cleaning items when the cleaning items assigned in the first cleaning plan in the cleaning item setting means are changed.

[0018] According to one embodiment of the toilet cleaning plan management system, if the cleaning items set for cleaning work are changed, the cleaning plan can be quickly updated with the changed content. Therefore, the toilet cleaning plan management system can always be optimized by updating the cleaning plan based on the changed cleaning items.

[0019] In a toilet cleaning plan management system according to one embodiment, the system further includes a means for setting cleaning personnel to clean the toilet space, and the cleaning plan creation means creates the cleaning plan by associating the cleaning items with the cleaning personnel based on the cleaning personnel information set by the means for setting cleaning personnel.

[0020] According to one embodiment of the toilet cleaning plan management system, a cleaning plan can be created that assigns the appropriate cleaning staff based on information about the cleaning staff. Therefore, the toilet cleaning plan management system enables appropriate staff assignment by creating a cleaning plan based on the cleaning staff's skills, available time, etc.

[0021] In a toilet cleaning plan management system according to one embodiment, if the cleaning staff assigned in the first cleaning plan is changed by the cleaning staff setting means, the second cleaning plan is changed based on the changed cleaning staff information.

[0022] According to the toilet cleaning plan management system according to one aspect of the embodiment, when the cleaning person in charge is changed, the cleaning plan can be updated so as to reflect the changed content. Therefore, the toilet cleaning plan management system can always be optimized by updating the cleaning plan based on the changed cleaning person-in-charge information.

The cleaning time estimation unit calculates the required cleaning time based on the input of the start and completion of cleaning, and the output device outputs the result of comparing the estimated cleaning time with the required cleaning time.

[0024] According to the toilet cleaning plan management system according to one aspect of the embodiment, the administrator can grasp the comparison result between the estimated result of the cleaning time and the actual cleaning time. Therefore, the toilet cleaning plan management system can grasp the actual situation of cleaning by comparing the estimated time required for cleaning with the actual required time.

[0025] In the toilet cleaning plan management system according to one aspect of the embodiment, the cleaning time estimation unit updates the information used to calculate the estimated cleaning time based on the required cleaning time.

[0026] According to the toilet cleaning plan management system according to one aspect of the embodiment, the parameters related to the calculation of the cleaning time can be adjusted according to the actual cleaning time. Therefore, the toilet cleaning plan management system can improve the estimation accuracy by updating the estimated time based on the required time.

[0027] A toilet cleaning plan management system according to one embodiment further comprises a cleaning time estimation unit that estimates the cleaning time for the cleaning items, and the cleaning time estimation unit calculates the estimated cleaning time in the first cleaning plan and the second cleaning plan.

[0028] According to one embodiment of the toilet cleaning plan management system, it is possible to calculate estimated cleaning times for both the cleaning plan before the change and the cleaning plan after the change. Therefore, the toilet cleaning plan management system can display efficiency improvements by visualizing the time before and after the change in the cleaning plan.

[0029] In a toilet cleaning plan management system according to one embodiment, the management terminal further comprises: cleaning management means for managing the progress of cleaning work based on input of completion of cleaning work; display setting means for setting a plurality of display modes indicating the status of the individual toilets on a display device provided in each of the plurality of individual toilets based on the cleaning management status of the cleaning management means; and display control means for controlling the plurality of display modes based on the setting conditions of the display setting means.

[0030] According to one embodiment of the toilet cleaning plan management system, the display on the display device can be controlled based on a display mode indicating the status of individual toilet stalls, thereby enabling a display that corresponds to the status of the individual toilet stalls. Therefore, since the status of each toilet stall is updated to the latest state by a display device installed in the toilet space, the toilet cleaning plan management system not only improves the convenience of users of the toilet space but also makes it easier for cleaners to understand the situation, thus providing a highly convenient system for both parties.

[0031] In a toilet cleaning plan management system according to one embodiment, the display setting means sets a first display mode and a second display mode that show information on whether the individual toilets are available or whether the individual toilets are vacant or occupied.

[0032] According to one embodiment of the toilet cleaning plan management system, by controlling the display on the display device based on the first display mode and the second display mode for individual toilet stalls, it is possible to display information according to the status of the individual toilet stalls. Therefore, the toilet cleaning plan management system allows toilet users and toilet cleaning staff to easily understand the status of the individual toilet stalls by displaying information such as the availability (occupancy, etc.) of individual toilet stalls, as in the first and second display modes.

[0033] In a toilet cleaning plan management system according to one embodiment, the display setting means includes a first display mode and a second display mode that indicate whether the individual toilet is available or whether it is occupied or full, and at least one third display mode that is assigned to the first display mode or the second display mode, the third display mode indicating the individual status of the individual toilet as indicated by the first display mode or the second display mode.

[0034] According to one embodiment of the toilet cleaning plan management system, the display on the display device can be controlled based on three types of display modes: a first display mode, a second display mode, and a third display mode, for individual toilet stalls, thereby enabling a display that corresponds to the status of the individual toilet stall. Therefore, the toilet cleaning plan management system can enable an appropriate display for individual toilet stalls by assigning additional information, such as the third display mode, to the display corresponding to the individual toilet stalls that need it.

[Modes for carrying out the invention]

[0037] The embodiments of the toilet cleaning plan management system disclosed herein will be described in detail below with reference to the attached drawings. However, the present invention is not limited to the embodiments described below.

[0038] [Introduction] (Example of toilet space configuration) Before describing the processes performed in the toilet cleaning plan management system 1 (see Figure 3) according to this embodiment, an example of the configuration of a toilet space (toilet room) will be described using Figure 1. Figure 1 is a diagram showing an example of the configuration of a toilet space according to this embodiment. Figure 1 is a diagram showing an example of the configuration of a toilet space according to the first embodiment.

[0039] As shown in Figure 1, the objects of processing related to control by the toilet cleaning plan management system 1 may include toilet space 2-1, toilet space 2-2, etc. When describing toilet spaces such as toilet space 2-1, toilet space 2-2, etc. without distinction, they may be referred to as "toilet space 2". For example, toilet space 2-1 and toilet space 2-2 may be toilet spaces 2 located on different floors of the same facility, such as a building. In Figure 1, toilet space 2 is shown as two toilet spaces 2-1 and toilet space 2-2, but there may be three or more toilet spaces 2. If there is only one toilet space 2 that the toilet cleaning plan management system 1 processes, for example, toilet space 2 may be only toilet space 2-1.

[0040] Furthermore, the toilet space 2-1 shown in Figure 1 includes toilet booths TB1 to TB5, which are individual toilets (toilet booths) that form individual spaces, and a shared space CS1, which is a shared space other than the toilet booths (also simply called "booths"). Note that when describing the toilet booths provided in toilet space 2 without distinguishing between them, such as toilet booth TB1, toilet booth TB2, toilet booth TB3, toilet booth TB4, toilet booth TB5, etc., they may be referred to as "toilet booth TB".

[0041] Figure 1 illustrates an example where toilet space 2 has five toilet booths TB, but toilet space 2 may have four or fewer, or six or more toilet booths TB. In other words, toilet space 2-1 shown in Figure 1 is merely one example of toilet space 2, and any configuration can be adopted for toilet space 2. For example, when the toilet cleaning plan management system 1 performs processing for multiple toilet spaces 2, the multiple toilet spaces 2 may include toilet spaces 2 that have one toilet booth TB. For example, toilet space 2 that has one toilet booth TB may be a space where toilet space 2 itself is a toilet booth TB, a so-called barrier-free toilet.

[0042] A toilet booth TB is a space (individual room) separated by a partition. Each toilet booth TB is equipped with a toilet 10 and functions as a place for a person to defecate. Each toilet booth TB is also equipped with an openable and closable door for entering the toilet booth TB. Since the doors of each toilet booth TB are similar to those of typical toilet booth TBs, a detailed explanation is omitted. Furthermore, a toilet booth TB does not have to be a space completely separated by a partition; there may be areas above or below the partition that are not separated from adjacent toilet booths TBs or common areas.

[0043] Furthermore, when describing shared spaces within toilet space 2, such as shared space CS1, without distinguishing between them, they may be referred to simply as "shared space CS." Shared space CS is a shared area within toilet space 2 where multiple people can stay simultaneously. For example, shared space CS includes an entrance to toilet space 2, washbasin facilities such as a vanity area 50, and pathways to each toilet booth TB. Shared space CS functions as a place for entering toilet space 2, washing hands, and moving to each toilet booth TB. If toilet space 2 functions as a men's toilet space 2, urinals may be placed in its shared space CS. In other words, shared space CS may also function as a place where people perform excretory acts.

[0044] Thus, toilet space 2 is a space provided within a facility or other space, where users enter and exit to use the toilet. For example, toilet space 2 has toilet booths TB, a shared space CS, etc., and is a space where toilet-related structures are arranged. For example, toilet space 2-1 shown in Figure 1 has toilet booths TB1 to TB5, each of which has multiple toilet units 10-1, 10-2, 10-3, 10-4, and 10-5, and a shared space CS1 where a washbasin vanity 50 is located. Thus, toilet space 2-1 has multiple toilet booths TB in which toilet units 10 are installed.

[0045] Next, referring to the toilet space 2 shown in Figure 1, the arrangement of each device in the toilet space 2 will be explained. Toilet device 10-1 is located in toilet booth TB1. Toilet device 10-2 is located in toilet booth TB2. Toilet device 10-3 is located in toilet booth TB3. Toilet device 10-4 is located in toilet booth TB4. Toilet device 10-5 is located in toilet booth TB5. Note that when describing toilet devices 10-1, 10-2, 10-3, 10-4, and 10-5 without distinction, they may be referred to as "toilet device 10".

[0046] Figure 1 shows an example where there are five toilet units 10, but any number of toilet units 10 can be used, and the number of toilet units 10 may be four or fewer, or six or more. Details of the functions of the toilet units 10 will be described later. In addition, descriptions of toilet units 10 may be interpreted as toilet booths TB in which those toilet units 10 are located. Similarly, descriptions of toilet booths TB may be interpreted as toilet units 10 located in those toilet booths TB. For example, toilet unit 10-1 may be interpreted as toilet booth TB1, and toilet booth TB1 may be interpreted as toilet unit 10-1.

[0047] The vanity unit 50 is located in the shared space CS provided within the toilet space 2. The vanity unit 50 is a toilet-use unit that has a washbasin for use by toilet users to wash their hands, wash their face, and look in the mirror. In Figure 1, the vanity unit 50 of toilet space 2-1 is located in the shared space CS1.

[0048] (Toilet space layout) Let me briefly explain some examples of the placement of toilet space 2. Toilet space 2 can be installed in any location as long as there is space in which it can be physically placed. In other words, any location can be chosen for toilet space 2. For example, toilet space 2 may be installed in a commercial facility such as a department store. Furthermore, the location of toilet space 2 is not limited to commercial facilities such as shops, but can be various types of facilities. For example, toilet space 2 may be installed in an amusement park, a stadium, or an office building. For example, toilet space 2 may be installed in a toilet located in a tourist area. For example, toilet space 2 may be installed in a park or parking lot. In other words, toilets may be installed outdoors in parks, parking lots, etc. Thus, toilet space 2 can be installed in any location as long as there is space in which it can be installed.

[0049] (Example of toilet booth configuration) Next, an example of the configuration of a toilet booth TB to be processed by the toilet cleaning plan management system 1 (see Figure 3) will be explained with reference to Figure 2. Figure 2 is a diagram showing an example of the configuration of a toilet booth according to the first embodiment. Specifically, Figure 2 shows a state in which only the door of toilet booth TB4 in the toilet space 2-1 shown in Figure 1 is closed, and the doors of the other four toilet booths TB are open, and is a front view as seen from the door (entrance) side.

[0050] As shown in Figure 2, a toilet unit 10-1 is located inside toilet booth TB1, with a display unit 20-1 and a detection unit 30-1 located near the entrance of toilet booth TB1. A toilet unit 10-2 is located inside toilet booth TB2, with a display unit 20-2 and a detection unit 30-2 located near the entrance of toilet booth TB2. A toilet unit 10-3 is located inside toilet booth TB3, with a display unit 20-3 and a detection unit 30-3 located near the entrance of toilet booth TB3. A toilet unit 10-4 is located inside toilet booth TB4, with a display unit 20-4 and a detection unit 30-4 located near the entrance of toilet booth TB4. A toilet unit 10-5 is located inside toilet booth TB5, with a display unit 20-5 and a detection unit 30-5 located near the entrance of toilet booth TB5.

[0051] In the following, when describing display units 20-1, 20-2, 20-3, 20-4, 20-5, etc., without distinguishing between them, they may be referred to simply as "display unit 20". In Figure 2, display unit 20 is a display device installed corresponding to each of the multiple toilet booths TB. Display unit 20-1 is a display device that displays information related to toilet booth TB1. Similarly, each of display units 20-2 to 20-5 is a display device that displays information related to each of the toilet booths TB2 to TB5.

[0052] The display unit 20 displays either a first display mode or a second display mode indicating the availability of toilet booth TB, or the occupancy status of toilet booth TB. The display unit 20 may also display at least one third display mode assigned to the first or second display mode. For example, the first and second display modes may be different colors, and the third display mode may be a visual symbol such as a pictogram. Specific examples of the first, second, and third display modes will be described later.

[0053] Figure 2 shows the case where toilet booth TB4 is in use, and display unit 20-4 displays the second display mode, while the other four toilet booths TB1 to TB3 and TB5 are vacant, and display units 20-1 to 20-3 and 20-5 display the first display mode. In Figure 2, hatching indicates that display unit 20-4, which is in use, displays red as an example of the second display mode. Hatching also indicates that display units 20-1 to 20-3 and 20-5, which are vacant, display blue as an example of the first display mode.

[0054] Note that blue is merely one example of the first display mode, and any color can be used for the first display mode, such as green or white, as long as it is distinguishable from the second display mode. Similarly, red is merely one example of the second display mode, and any color can be used for the second display mode, such as yellow or purple, as long as it is distinguishable from the first display mode. Further examples of displays, including those corresponding to the third display mode, will be described later. In addition, the display unit 20 may be in a non-display state when there is no need to display anything (for example, outside of business hours of the facility where the corresponding toilet booth TB is located).

[0055] Furthermore, the arrangement of the display unit 20 shown in Figure 2 is merely an example, and the display unit 20 may be arranged in any manner as long as it can present the desired information to the toilet user. For example, the display unit 20 is not limited to being placed within the toilet space 2, but may be placed anywhere. For example, the display unit 20 may be placed at the entrance of the toilet space 2. In this case, a display device such as digital signage (a screen installed in front of the toilet space 2) may function as the display unit 20 that displays information corresponding to multiple toilet booths TB. In this case, the display unit 20 may display a floor plan of the corresponding toilet space 2, and superimpose information corresponding to each toilet booth TB (first display mode, second display mode, third display mode, etc.) onto the area corresponding to each toilet booth TB in the floor plan.

[0056] The display unit 20 is not limited to a device placed in the toilet space 2 or facility, but may also be a portable device such as a smartphone used by the toilet user. In this case, the toilet cleaning plan management system 1 may transmit information to be displayed on the display unit 20 of the smartphone used by the toilet user, and the display unit 20 used by the toilet user may display the received information. For example, the display unit 20 used by the toilet user may display the information received from the toilet cleaning plan management system 1 using a display application or the like.

[0057] Furthermore, when describing detection units 30-1, 30-2, 30-3, 30-4, 30-5, etc., without distinguishing between them, they may be simply referred to as "detection unit 30". Note that the arrangement of detection unit 30 shown in Figure 2 is merely an example, and detection unit 30 may be arranged in any manner as long as the desired information can be detected.

[0058] The detection unit 30 is a detection device that performs detections related to the toilet booth TB. The detection unit 30 has a sensor that detects entry into or exit from the toilet booth TB or use of the toilet booth TB. The detection unit 30 is a sensor (detection unit) that detects the use of the toilet booth TB. The detection unit 30 detects information indicating the use of the toilet booth TB. The detection unit 30 performs detections related to the toilet booth TB in which the toilet equipment 10 is located. The detection unit 30 functions as a detection unit that detects the entry and exit of a person (user) to or from the toilet booth TB in which the toilet equipment 10 is located. The detection unit 30 may be implemented by various sensors.

[0059] For example, the detection unit 30 may be various types of sensors such as a human body detection sensor, an action detection sensor, or a seating detection sensor. The detection unit 30 may be a door sensor installed on the door of the toilet booth TB to detect the opening and closing of the door of the toilet booth TB. The detection unit 30 may be an image sensor that captures images of the area around the door of the toilet booth TB. The detection unit 30 may be a seating sensor that detects when a user sits on the toilet unit 10. The detection unit 30 may be a sensor that detects whether or not the toilet is flushed or whether or not the toilet remote control is operated. Furthermore, the detection unit 30 may be a sensor (such as a human motion sensor) installed in relation to the user's personal hygiene.

[0060] The above is merely an example, and the detection unit 30 may be implemented by any means that can detect information that can be used to estimate at least one of the following: the user entering or leaving the toilet booth TB, or the user using the toilet device 10. The toilet device 10 and the detection unit 30 may be integrated. In this case, the toilet device 10 having the detection unit 30 may be included in the toilet cleaning plan management system 1. The placement of the detection unit 30 is not limited to placement on the outer wall surface of the toilet booth TB as shown in Figure 2, as long as it can detect the use of the toilet device 10. It may also be installed on the ceiling, inner wall surface, floor, etc. of the toilet booth TB, or mounted on the toilet seat of the toilet device 10.

[0061] The detection unit 30 includes, for example, a communication unit (e.g., a communication circuit) having wireless communication capabilities, and is wirelessly connected to the management terminal 100. For example, when the detection unit 30 detects a person entering or leaving a toilet booth TB in which a toilet device 10 is installed, it transmits detection information, such as the date and time of the detection, to the management terminal 100 along with identification information (such as an ID) that identifies the toilet booth TB or the toilet device 10 installed in the toilet booth TB. For example, the detection unit 101 may transmit detection information, such as the time (usage time) from when a person enters the toilet booth TB in which the toilet device 10 is installed until they leave, to the management terminal 100 along with identification information (such as an ID) that identifies the toilet booth TB or the toilet booth TB in which the toilet device 10 installed in the toilet booth TB is installed. Specific examples of the processing targeting the toilet booth TB described above will be described later.

[0062] (Configuration of the toilet cleaning plan management system) Next, the configuration of the toilet cleaning plan management system 1 will be described with reference to Figure 3. Figure 3 is a diagram showing an example configuration of the toilet cleaning plan management system according to the first embodiment. Specifically, Figure 3 shows the configuration of the toilet cleaning plan management system 1.

[0063] The toilet cleaning plan management system 1 shown in Figure 3 includes a plurality of toilet booths TB, each having a toilet bowl device 10, a display unit 20, and a detection unit 30, as well as a management terminal 100, an output device 200, and a cleaning staff terminal 300.

[0064] The toilet unit 10 is the object of use for the toilet when a user defecates or urinates. The toilet unit 10 is located in a toilet booth TB provided within the toilet space 2. For example, the toilet unit 10 has a toilet seat unit that includes a toilet seat on which the user sits, and an operating unit for operating a nozzle for dispensing water for washing (the user's private parts, etc.). In addition to the toilet seat unit, the toilet unit 10 has various components such as a toilet lid and a toilet bowl to realize the function of a toilet, but a detailed explanation is omitted. The display unit 20 displays information related to the toilet booth TB. The detection unit 30 detects the use of the toilet booth TB.

[0065] The management terminal 100 is an information processing device (computer) that performs control processing to control the display of information related to toilets. The management terminal 100 creates a cleaning plan that shows the schedule for cleaning the toilet booths TB.

[0066] For example, the management terminal 100 may be a cloud server or the like. The management terminal 100 is connected to the display unit 20, detection unit 30, output device 200, and cleaning staff terminal 300 wirelessly or via a wired connection via a predetermined network N such as the Internet. The management terminal 100 may be connected to the display unit 20, detection unit 30, output device 200, cleaning staff terminal 300, etc., in any way as long as it is capable of sending and receiving information, and may be connected wirelessly or via a wired connection.

[0067] The management terminal 100 creates a cleaning plan for the toilet space 2 by, for example, assigning cleaning personnel with the skills corresponding to each cleaning item (hereinafter also referred to as a cleaning item group) that divides the cleaning work of the toilet space 2 to be cleaned, and by determining the cleaning frequency using information such as the usage status of the toilet equipment 10 transmitted from the detection unit 30.

[0068] The management terminal 100 may be located outside the toilet space 2 or inside the toilet space 2. For example, the management terminal 100 may be a server device located in a facility where the toilet space 2 is provided.

[0069] The output device 200 is a device that outputs information generated by the management terminal 100 to an external source. For example, the output device 200 displays the cleaning plan created by the management terminal 100 on its screen. The method of outputting information by the output device 200 is not particularly limited; for example, the information to be output may be displayed on the screen of another device, or the information to be output may be printed using a printer function.

[0070] The output device 200 transmits information to other devices. For example, the output device 200 transmits information generated by the management terminal 100 to an administrator device used by the administrator. The administrator device displays the information received from the output device 200. In this case, the output device 200 and the management terminal 100 may be a single unit.

[0071] Furthermore, the output device 200 outputs the result of comparing the estimated cleaning time with the actual cleaning time. For example, the output device 200 outputs information comparing the estimated cleaning time for the toilet space 2, which is set according to the cleaning plan and calculated by the cleaning time estimation unit 131 (described later), with the actual cleaning time required for the cleaning work, to an external administrator device or displays it on a screen.

[0072] The cleaning terminal 300 is an information processing terminal used by the cleaning staff who perform cleaning work in the toilet space 2. For example, the cleaning terminal 300 is a device that can receive and display the cleaning plan created by the management terminal 100, and can be implemented using a smartphone or tablet device.

[0073] For example, if a cleaning staff member determines that cleaning is unnecessary for a cleaning item included in the cleaning plan described later, the cleaning staff terminal 300 can receive input from the cleaning staff member indicating that cleaning is unnecessary and send it to the management terminal 100.

[0074] Furthermore, the cleaning terminal 300 receives inputs indicating the start and completion of cleaning for the toilet space 2 as set out in the cleaning plan. For example, the cleaning terminal 300 receives inputs from the cleaning staff indicating the start and completion of cleaning work for the toilet space 2 as set out in the cleaning plan described later, and transmits them to the management terminal 100.

[0075] The above is merely an example, and the toilet cleaning plan management system 1 can employ any device configuration and arrangement. For example, the toilet cleaning plan management system 1 may include an input device that receives input related to cleaning. In this case, the input device is an information processing device (computer) that can be used by toilet cleaners, and is connected to the management terminal 100 wirelessly or via a wired connection through a predetermined network N such as the Internet.

[0076] Furthermore, the toilet cleaning plan management system 1 may include a detection unit (shared equipment detection unit) that detects each shared facility such as the washbasin vanity unit 50. The toilet cleaning plan management system 1 may also include multiple management terminals 100, multiple output devices 200, multiple cleaning staff terminals 300, etc.

[0077] [First Embodiment] (Processing details of the toilet cleaning plan management system) The following describes the processing according to the first embodiment of the toilet cleaning plan management system 1 described above. Figure 4 is a diagram illustrating the processing content of the toilet cleaning plan management system according to the first embodiment. The toilet cleaning plan management system 1 according to the first embodiment includes a management terminal 100 that manages the cleaning plan of a toilet space 2 in which a plurality of toilet booths TB are set, and an output device that outputs the cleaning plan managed by the management terminal 100. The toilet cleaning plan management system 1 sets at least one cleaning item from a plurality of cleaning items that divide a plurality of cleaning tasks in the toilet space 2, and creates a cleaning plan for the toilet space 2 based on the cleaning item.

[0078] Furthermore, the toilet cleaning plan management system according to the first embodiment creates a cleaning plan for the toilet space 2 based on cleaning staff information that is stored in association with the cleaning skill categories and cleaning staff for each of the multiple cleaning staff members who clean the toilet space 2.

[0079] For example, the toilet cleaning plan management system 1, as shown in Figure 4, has a management terminal 100 and an output device 200. The management terminal 100 creates a cleaning plan for the first item and a cleaning plan for the second item, respectively, from setting information for the first and second items that divide the cleaning work of the toilet space 2, which is the target of the cleaning work, and setting information for the cleaning items that can be handled by the cleaning staff member in charge of the cleaning work, based on their skills. The output device 200 then outputs each of the created cleaning plans by displaying them on a screen or transmitting them to an external device.

[0080] As a result, the toilet cleaning plan management system 1 can create appropriate cleaning plans for each of the multiple categories of toilet cleaning work. Furthermore, the toilet cleaning plan management system 1 can assign appropriate cleaning personnel to each of the multiple categories of toilet cleaning work.

[0081] (Functional configuration of the management terminal) The functional configuration of the control device will be described below with reference to Figure 5. Figure 5 is a block diagram showing an example of the configuration of a management terminal according to the first embodiment. As shown in Figure 5, the management terminal 100A according to the first embodiment has a communication unit 110, a control unit 120, and a storage unit 140.

[0082] The communication unit 110 is implemented, for example, by a communication circuit. The communication unit 110 is connected to a predetermined network N (see Figure 3) by wire or wireless connection and transmits and receives information with an external information processing device. For example, the communication unit 110 is connected to a predetermined network N (see Figure 3) by wire or wireless connection and transmits and receives information with other devices such as the display unit 20, the detection unit 30, the output device 200, and the cleaning terminal 300.

[0083] The storage unit 140 is implemented by, for example, a semiconductor memory element such as RAM (Random Access Memory) or flash memory, or a storage device such as a hard disk or optical disc. For example, the storage unit 140 is a computer-readable recording medium that non-temporarily records data used by information processing programs such as control processing.

[0084] As shown in Figure 5, the storage unit 140 according to the first embodiment includes a cleaning item information storage unit 141, a cleaning work information storage unit 142, a cleaning staff information storage unit 143, a cleaning necessity determination information storage unit 144, and a display setting information storage unit 145. The storage unit 140 stores various information necessary for processing, not limited to the cleaning item information storage unit 141, the cleaning work information storage unit 142, the cleaning staff information storage unit 143, the cleaning necessity determination information storage unit 144, and the display setting information storage unit 145.

[0085] The cleaning item information storage unit 141 stores a group of cleaning items corresponding to the toilet space 2 to be cleaned. Figure 6 is a diagram illustrating the relationship between the toilet space and cleaning items according to the first embodiment. For example, the cleaning item information storage unit 141 stores information about the location of the toilet space 2 to be cleaned (building, floor, space, etc.) and the cleaning items associated with that toilet space 2. As shown in Figure 6, the cleaning item information storage unit 141 stores, for example, that the first group of items and the second group of items, described later, are associated with the men's toilet on the 1st floor of Building A.

[0086] The cleaning work information storage unit 142 stores the content of cleaning tasks assigned to multiple items. Figure 7 is a diagram illustrating the relationship between cleaning tasks and cleaning items according to the first embodiment. For example, the cleaning work information storage unit 142 stores the content of cleaning tasks assigned to each of the first and second item groups, which are divided into cleaning tasks for the toilet space 2. As shown in Figure 7, the cleaning work information storage unit 142 stores, for example, that the first item group is assigned cleaning tasks such as toilet bowl cleaning, urinal cleaning, floor cleaning, and garbage collection, and the second item group is assigned cleaning tasks such as sink cleaning, paper replenishment, and liquid soap replenishment.

[0087] The cleaning staff information storage unit 143 stores the cleaning skill categories for each of the multiple cleaning staff members who clean the toilet space 2, associating them with the cleaning staff members themselves. Figure 8 is a diagram illustrating the relationship between cleaning staff members and skill categories according to the first embodiment. For example, the cleaning staff information storage unit 143 stores for each cleaning staff member a cleaning skill category used to assign cleaning staff members to cleaning work, such as name, gender, contract type, and length of service. Note that the cleaning staff information storage unit 143 is not limited to storing a cleaning skill category for each cleaning staff member; for example, it can also store the corresponding skill categories associating them with each group of cleaning staff members.

[0088] Furthermore, the cleaning staff information storage unit 143 stores multiple cleaning item groups and multiple cleaning skill categories in association. For example, the cleaning staff information storage unit 143 stores the settings for the skill categories used to determine which cleaning staff member is responsible for each item group.

[0089] As shown in Figure 8(1), the cleaning staff information storage unit 143 stores, for example, information about staff member "Sato," stating that he is a male full-time employee with 12 years of service. Also, as shown in Figure 8(2), the cleaning staff information storage unit 143 stores that the cleaning skill category responsible for the first item group is that of a full-time employee, and the cleaning skill category responsible for the second item group is that of a temporary employee.

[0090] Furthermore, the aforementioned cleaning skill categories are stored in association with at least the first category group. For example, cleaning skill categories such as full-time employee or three or more years of service are associated only with the first category group, which requires a higher level of cleaning skill than the work content of the second category group. As a result, cleaning personnel are selected based on cleaning skills only for the first category group, while all cleaning personnel can be assigned to the second category group.

[0091] The cleaning necessity determination information storage unit 144 stores information that serves as a criterion for determining whether cleaning work is necessary. Figure 9 is a diagram illustrating the process related to the cleaning necessity determination according to the first embodiment. For example, the cleaning necessity determination information storage unit 144 stores the timing of the cleaning necessity determination when determining whether cleaning is necessary based on the usage status of the equipment to be cleaned, and the usage status of the equipment that serves as the criterion for determining whether cleaning is necessary.

[0092] As shown in Figure 9(1), the cleaning necessity determination information storage unit 144 stores information for the cleaning necessity determination timing item, for example, setting that the cleaning necessity of the cleaning target should be determined 30 minutes before the cleaning time. As shown in Figure 9(2), the cleaning necessity determination information storage unit 144 stores setting information for each cleaning decision criterion for the second group of cleaning tasks stored in the cleaning item information storage unit 141 mentioned above. Specifically, the cleaning necessity determination information storage unit 144 stores setting information that cleaning is necessary when there are 100 or more users for washroom cleaning, when there are 2 or fewer rolls in stock for paper replenishment, and when the remaining amount of liquid soap is 20% or less for liquid soap replenishment.

[0093] The display setting information storage unit 145 stores information that controls the display content to be displayed on the display unit 20 of each toilet booth (TB). For example, the display setting information storage unit 145 stores setting information that includes information used to determine whether or not to display something. For example, the display setting information storage unit 145 stores setting information that includes information related to thresholds used in the determination process. For example, the display setting information storage unit 145 stores setting information that includes information used to determine which display mode to use, such as the first display mode, the second display mode, and the third display mode. For example, the display setting information storage unit 145 stores setting information for each toilet booth (TB) that includes information indicating the conditions (setting conditions) for which display mode to use, such as the first display mode, the second display mode, and the third display mode.

[0094] Returning to Figure 5, let's continue the explanation. The control unit 120 is implemented, for example, by a CPU (Central Processing Unit) or GPU (Graphics Processing Unit), which executes a program stored inside the management terminal 100 (for example, an information processing program such as the control processing related to this disclosure) using RAM or the like as a working area. Alternatively, the control unit 120 can be implemented by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or FPGA (Field Programmable Gate Array).

[0095] As shown in Figure 5, the control unit 120 includes a cleaning item setting unit 121, a cleaning plan creation unit 122, an acquisition unit 123, a cleaning necessity determination unit 124, a notification unit 125, a cleaning management unit 126, a display setting unit 127, and a display control unit 128, and realizes or executes the information processing functions and operations described below. Note that the internal configuration of the control unit 120 is not limited to the configuration shown in Figure 5, and other configurations are also acceptable as long as they perform the information processing described later.

[0096] The cleaning item setting unit 121 sets at least one cleaning item from among multiple cleaning items that divide the multiple cleaning tasks in the toilet space 2. For example, the cleaning item setting unit 121 sets the group of cleaning items stored in the cleaning item information storage unit 141 as the cleaning items to be targeted in the cleaning plan described later, for the toilet space 2 to be cleaned.

[0097] Here, we will explain the cleaning items that are subject to processing by the cleaning item setting unit 121. For example, cleaning items include a first item that requires cleaning at a predetermined frequency and time, and a second item that requires cleaning at a different frequency or for a shorter time than the first item. Specifically, cleaning items for the toilet space 2 include a first group of items that are cleaned regularly at a predetermined frequency and for a certain amount of time, such as toilet bowl cleaning and urinal cleaning, and a second group of items that are cleaned less frequently and for a shorter time than the first group, such as sink cleaning and paper replenishment (see Figure 7).

[0098] For example, the cleaning items include items indicated by the type of work performed at the cleaning locations in toilet space 2. Specifically, the cleaning items include items indicated by the type of work performed at the cleaning locations in toilet space 2, such as floor cleaning and garbage collection (see Figure 7). For example, the cleaning items include items indicated by the equipment unit, including multiple toilets and faucets installed in toilet space 2. Specifically, the cleaning items include items indicated by the equipment unit, including multiple toilets and faucets installed in toilet space 2, such as toilet cleaning and urinal cleaning (see Figure 7).

[0099] The cleaning plan creation unit 122 creates a cleaning plan for the toilet space 2 based on the cleaning items. The cleaning plan creation unit 122 will now explain a specific example of the cleaning plan created by the cleaning plan creation unit 122. Figure 10 is a diagram showing an example of a cleaning plan according to the first embodiment.

[0100] Figure 10 shows the cleaning plan for July in toilet space 2, which is the target of cleaning. Figure 10(1) shows the cleaning plan for the first item group. Figure 10(2) shows the cleaning plan for the second item group.

[0101] As shown in Figure 10(1), the cleaning plan creation unit 122 creates a cleaning plan indicating, for example, that on Monday, July 1st, the men's restrooms on the 1st floor and 2nd floor of Building A will be cleaned by cleaning staff member "Sato," who is classified into the cleaning skill category corresponding to the first item group, between 7:00 and 9:00. As shown in Figure 10(2), the cleaning plan creation unit 122 also creates a cleaning plan indicating, for example, that on Tuesday, July 2nd, the men's restroom on the 1st floor of Building A will be cleaned by cleaning staff member "Suzuki" in two separate cleaning sessions: one between 7:00 and 7:30, and another between 13:00 and 13:30.

[0102] Next, we will explain the processing examples of the cleaning plan creation unit 122 in order. For example, the cleaning plan creation unit 122 creates a cleaning plan based on the settings of either or both of the first and second items. Specifically, the cleaning plan creation unit 122 refers to the cleaning frequency and cleaning time set for each of the first and second item groups and creates a cleaning plan for each of the first and second item groups.

[0103] For example, if the cleaning plan creation unit 122 includes both item 1 and item 2 in the cleaning items, it creates a cleaning plan that performs the cleaning of item 2 in accordance with the cleaning timing of item 1. Specifically, if both item 1 and item 2 are set in the cleaning plan to be created, the cleaning plan creation unit 122 determines the cleaning timing of item 2 in accordance with the cleaning timing of item 1, which has a lower cleaning frequency and longer cleaning time, thereby creating a single cleaning plan that combines item 1 and item 2.

[0104] As an example, the cleaning plan creation department 122, for the men's restroom on the 1st floor of Building A (see Figure 6), which has two sets of cleaning items (a first group and a second group), creates a single cleaning plan by determining the work time for the second group of items, which has shorter cleaning times (such as cleaning the washbasins), to match the work time for the first group of items, which has longer cleaning times (such as cleaning the toilet bowls).

[0105] For example, the cleaning plan creation unit 122 creates a cleaning plan for the first or second item based on the judgment of the cleaning necessity determination unit 124. Specifically, the cleaning plan creation unit 122 creates a cleaning plan for the cleaning items of the toilet space 2 to be cleaned when the cleaning necessity determination unit 124, described later, determines that cleaning is necessary.

[0106] Here, we will explain with specific examples the process of creating a cleaning plan for cleaning items that have been determined to require cleaning by the cleaning necessity determination unit 124. Figure 11 is a diagram illustrating the process of creating a cleaning plan for cleaning items that have been determined to require cleaning according to the usage status of the equipment according to the first embodiment. Figure 11 shows an example of the process when the washbasin area of ​​the men's restroom on the 2nd floor of Building A, the urinal area of ​​the men's restroom on the 1st floor of Building A, and the common area of ​​the men's restroom on the 1st floor of Building A are determined to require cleaning.

[0107] As shown in Figure 11, the cleaning plan creation unit 122 assigns cleaning personnel "Sato," who is classified into the cleaning skill category corresponding to the first group of items, which includes floor cleaning and garbage collection, and "Suzuki," who is classified into the cleaning skill category corresponding to the second group of items, which includes washbasin cleaning, floor cleaning, and garbage collection, to the washbasin area of ​​the men's restroom on the 2nd floor of Building A, the urinal area of ​​the men's restroom on the 1st floor of Building A, and the common area of ​​the men's restroom on the 1st floor of Building A, which the cleaning necessity determination unit 124 has determined to require cleaning. The cleaning plan creation unit 122 then creates a cleaning plan with cleaning items corresponding to each area, including washbasin cleaning, floor cleaning, and garbage collection. As a result, the cleaning plan creation unit 122 can create cleaning items only for the areas that the cleaning necessity determination unit 124 has determined to require cleaning, on an irregular, on-demand basis.

[0108] Furthermore, the cleaning plan shown in the example in Figure 11 can be notified to the cleaning staff's terminal 300 by the notification unit 125 (described later) each time it is created. In addition, the cleaning plan creation unit 122 can update the cleaning plan created from the cleaning staff terminal 300 by adding "Completed" to the completion input column for cleaning items for which the completion input of the work has been received.

[0109] For example, the cleaning plan creation unit 122 creates a cleaning plan for the toilet space 2 based on the cleaning staff information stored in the cleaning staff information storage unit 143. Specifically, the cleaning plan creation unit 122 assigns cleaning staff members who have cleaning skill categories corresponding to the cleaning items set by the cleaning item setting unit 121, and creates a cleaning plan for the toilet space 2.

[0110] For example, if the cleaning plan creation unit 122 has designated full-time employees as the cleaning skill category corresponding to the first item group (see Figure 8(2)), it will create a cleaning plan for the first item group by assigning either "Sato" or "Takahashi," who are cleaning staff members with full-time employment contracts, according to the toilet space 2 to be cleaned.

[0111] For example, the cleaning plan creation unit 122 creates a cleaning plan for the toilet space 2 based on the cleaning staff information stored in the cleaning staff information storage unit 143 and the usage information. Specifically, the cleaning plan creation unit 122 creates a cleaning plan by assigning cleaning staff members with the corresponding cleaning skill categories to cleaning items that are determined to require cleaning based on the usage status information of the equipment to be cleaned, which is acquired by the acquisition unit 123 described later.

[0112] As an example, the cleaning plan creation unit 122 determines that the number of users detected by the human body detection sensor installed at the entrance of the toilet space 2 by the acquisition unit 123 (described later) is 150 or more, and that floor cleaning of the toilet space 2 is required. In such a situation, the unit creates a cleaning plan assigning cleaning staff member "Takahashi," who is classified into the cleaning skill category corresponding to the first item group for which floor cleaning is set, to clean the floor of the toilet space 2.

[0113] The acquisition unit 123 acquires information on the usage status of equipment installed in the toilet space 2. For example, the acquisition unit 123 receives detection information from the detection unit 30 regarding the toilet booth TB. Specifically, the acquisition unit 123 acquires information on the number of users detected by various sensors such as human body detection sensors, behavior detection sensors, and seating detection sensors, as well as information on the usage status of equipment such as the number of times toilets and urinals have been flushed, from the detection unit 30 installed in the toilet space 2 to be cleaned.

[0114] The cleaning necessity determination unit 124 determines whether equipment needs to be cleaned based on the equipment usage information acquired by the acquisition unit 123. For example, the cleaning necessity determination unit 124 determines that equipment needs cleaning if the usage information of the equipment installed in the toilet space 2 to be cleaned, acquired by the acquisition unit 123, matches the cleaning necessity determination criteria stored in the cleaning necessity determination information storage unit 144. Specifically, the cleaning necessity determination unit 124 determines that the washbasin vanity area 50 in the toilet space 2 needs cleaning if the number of users detected by the human body detection sensor that detects users of the washbasin vanity area 50 in the toilet space 2 is 100 or more.

[0115] The cleaning necessity determination unit 124 notifies the cleaning plan creation unit 122 of whether cleaning is necessary for the cleaning plan created by the cleaning plan creation unit 122. For example, the cleaning necessity determination unit 124 determines whether the usage status of the equipment acquired by the acquisition unit 123 meets the cleaning necessity determination criteria at the cleaning necessity determination timing stored in the cleaning necessity determination information storage unit 144, and notifies the cleaning plan creation unit 122 of whether cleaning is necessary. If the cleaning plan creation unit 122 is notified that cleaning is not necessary, it deletes the cleaning plan for the equipment that was determined not to need cleaning and updates the cleaning plan.

[0116] The cleaning necessity determination unit 124 updates the criteria for determining whether cleaning is necessary based on the input indicating that cleaning is not required. For example, when the cleaning staff inputs to the aforementioned cleaning terminal 300 that cleaning is not required, the cleaning necessity determination unit 124 updates the cleaning necessity determination criteria stored in the cleaning necessity determination information storage unit 144 to reduce the frequency of cleaning.

[0117] Here, we will explain the process when "no cleaning required" is entered, using a specific example. Figure 12 is a diagram illustrating the process of updating the judgment criteria based on the cleaning requirement determination according to the first embodiment. Figure 12 shows an example of a cleaning plan related to item 2 on Tuesday, July 2nd.

[0118] As shown in Figure 12, the cleaning necessity determination unit 124 makes a determination at 6:30, 30 minutes before the start time of the cleaning work at 7:00, for the men's restroom on the 1st floor of Building A on Tuesday, July 2, from 7:00 to 7:30 as indicated in the cleaning plan. The cleaning necessity determination unit 124 then notifies the cleaning plan creation unit 122 that it has determined that cleaning is necessary because the number of users detected by the human body detection sensor installed at the entrance of the restroom space 2 is 150 or more. The cleaning plan creation unit 122 then creates a cleaning plan in which "Required" is written in the necessity column of the system output in Figure 12.

[0119] Subsequently, at 6:55, the cleaning staff member "Suzuki" visually inspected the men's restroom on the 1st floor of Building A to determine if cleaning was necessary. After determining that cleaning was required, he carried out the cleaning work from 6:55 to 7:20 and entered the work results into the cleaning staff terminal 300. The cleaning staff terminal 300 then notified the cleaning plan creation unit 122 of the entered work results. The cleaning plan creation unit 122 then created a cleaning plan in the cleaning staff input column of Figure 12, which includes the results and whether cleaning was necessary.

[0120] In the aforementioned 7:00-7:30 cleaning plan, both the cleaning necessity determination unit 124 and the visual inspection by the cleaning staff determined that cleaning was necessary, so the criteria for determining whether cleaning is necessary remain unchanged.

[0121] Similarly, the cleaning necessity determination unit 124, after performing a cleaning necessity determination for the men's restroom on the 2nd floor of Building A from 7:30 to 8:00, notifies the cleaning plan creation unit 122 that cleaning is necessary. The cleaning plan creation unit 122 then creates a cleaning plan in which "Required" is written in the necessity column of the system output shown in Figure 12.

[0122] However, at 7:28, the cleaning staff member "Suzuki" visually inspected the men's restroom on the 2nd floor of Building A and determined that it did not need cleaning. In this case, "Suzuki" enters the time spent on the visual inspection (7:28-7:30) into the cleaning staff terminal 300 as work record and notifies the cleaning plan creation unit 122. The cleaning plan creation unit 122 then creates a cleaning plan in the cleaning staff input column of Figure 12, which includes the actual work record and whether cleaning was necessary or not.

[0123] In the aforementioned 7:30-8:00 cleaning plan, the cleaning necessity determination unit 124 determined that cleaning was necessary, but the cleaning staff determined that cleaning was not necessary based on visual inspection. Therefore, the cleaning necessity determination unit 124 updates the cleaning necessity determination criteria so that cleaning is not necessary based on the usage status of the equipment from the previous cleaning operation to the current cleaning operation.

[0124] Furthermore, the cleaning necessity determination unit 124 can also update its cleaning necessity determination criteria so that, even if it determines that cleaning is unnecessary as a result of its cleaning necessity determination, the usage status of the equipment between the previous cleaning operation and the current cleaning operation indicates that cleaning is not necessary, as shown in the cleaning plan for the men's restroom on the 3rd floor of Building A from 8:00 to 8:30.

[0125] The notification unit 125 notifies the cleaning terminal 300, which is held by the cleaning staff member associated with the cleaning plan, of the cleaning plan. For example, the notification unit 125 notifies the cleaning terminal 300, which is held by the cleaning staff member who is incorporated into the cleaning plan created by the cleaning plan creation unit 122, of the cleaning plan. Specifically, each time the cleaning plan creation unit 122 creates a cleaning plan, the notification unit 125 notifies the cleaning terminal 300, which is held by the cleaning staff member assigned to the cleaning items described in the cleaning plan, of the cleaning plan.

[0126] The cleaning management unit 126 manages the progress of cleaning work based on the input of completion of cleaning work. For example, the cleaning management unit 126 manages the progress of cleaning work by updating the area of ​​the toilet space 2 to be cleaned, as indicated by the cleaning item for which the cleaning staff member has notified the completion of work input to the cleaning staff terminal 300, to reflect the status of completed cleaning.

[0127] The display setting unit 127 sets multiple display modes for each of the multiple display units 20 provided in each of the multiple toilet booths TB, indicating the status of each toilet booth TB. For example, the display setting unit 127 registers setting information indicating the setting of the display mode for each toilet booth TB, which is input by the administrator via the content CT1 described later, in the display setting information storage unit 145.

[0128] For example, the display setting unit 127 has a first display mode and a second display mode that show information on whether the toilet booth TB is available or full, and at least one third display mode that is assigned to the first display mode or the second display mode, and the third display mode is set to show the individual status of the toilet booth TB shown by the first display mode or the second display mode.

[0129] Here, we will explain the display modes set by the display setting unit 127 with specific examples. Figure 13 is a diagram showing an example of the display in the toilet cleaning plan management system according to the first embodiment. In Figure 6, different reference numerals are used to describe the display mode of the display unit 20, but when describing the display units 20a, 20b, 20c, 20d, 20e etc. without distinction, they will be referred to as "display unit 20".

[0130] Display unit 20a in Figure 13 corresponds to the display modes of display units 20-1 to 20-3 and 20-5 in Figure 2, and is shown with hatching when display unit 20 displays the first display mode FD, which is blue. Display unit 20b in Figure 13 corresponds to the display mode of display unit 20-4 in Figure 2, and is shown with different hatching than display unit 20a when display unit 20 displays the second display mode SD, which is red.

[0131] Furthermore, the display unit 20c in Figure 13 shows the case where the display unit 20 displays the first display mode FD of the display unit 20a in Figure 13, with the addition of a third display mode TD11, which is a pictogram indicating that the toilet booth TB is in a state suitable for use by the user. When explaining the third display mode TD11, third display mode TD21, third display mode TD22, etc. without distinguishing between them, it will be written as "third display mode TD".

[0132] Thus, the first display mode FD to which the third display mode TD11 is assigned indicates that the individual state of the corresponding toilet booth TB is suitable for use by the user. For example, the third display mode TD added to the first display mode FD, such as the third display mode TD11, indicates that the toilet booth TB has been used less than a predetermined number of times, the vacant time of the toilet booth TB is longer than a predetermined time, the toilet booth TB has not been judged to be abnormal, and the toilet booth TB has just been cleaned. For example, the administrator sets which of the following corresponds to the third display mode TD added to the first display mode FD, such as the third display mode TD11: the toilet booth TB has been used less than a predetermined number of times, the vacant time of the toilet booth TB is longer than a predetermined time, the toilet booth TB has not been judged to be abnormal, and the toilet booth TB has just been cleaned.

[0133] In the case of display unit 20c, the third display mode TD11 is assigned to the first display mode FD. The first display mode FD to which the third display mode TD11 is assigned, i.e., a display mode like display unit 20c, indicates that the toilet booth TB is in a recommended state for use. That is, the toilet booth TB corresponding to display unit 20c is in a state where use is recommended. The first display mode FD to which the third display mode TD11 is not assigned, i.e., a display mode like display unit 20a, indicates that the toilet booth TB is vacant or not recommended for use. In addition, the second display mode SD, i.e., a display mode like display unit 20b, indicates that the toilet booth TB is full.

[0134] Furthermore, display unit 20d in Figure 13 shows the case where display unit 20 displays a third display mode TD21, which is a pictogram indicating that the toilet booth TB is unavailable, in addition to the second display mode SD of display unit 20b in Figure 13. Furthermore, display unit 20e in Figure 13 shows the case where display unit 20 displays a third display mode TD22, which is a pictogram indicating that the toilet booth TB is in an abnormal state, in addition to the second display mode SD of display unit 20b in Figure 13.

[0135] Thus, the second display mode SD to which the third display mode TD21 and TD22 are assigned indicates that the individual status of the corresponding toilet booth TB is unavailable or abnormal. For example, the third display mode TD added to the second display mode SD, such as the third display mode TD21 and TD22, indicates that the toilet booth TB has been used more than a predetermined number of times, the vacant time of the toilet booth TB is less than a predetermined time, the toilet booth TB has been determined to be abnormal, the toilet booth TB is on cleaning standby, and the toilet booth TB is in power saving mode. For example, the administrator sets which of the following corresponds to the third display mode TD added to the second display mode SD, such as the third display mode TD21 and TD22: the toilet booth TB has been used more than a predetermined number of times, the vacant time of the toilet booth TB is less than a predetermined time, the toilet booth TB has been determined to be abnormal, the toilet booth TB is on cleaning standby, and the toilet booth TB is in power saving mode.

[0136] In the case of display units 20d and 20e, the third display modes TD21 and TD22 are assigned to the second display mode SD. The second display mode SD to which the third display modes TD21 and TD22 are assigned, i.e., the display modes such as display units 20d and 20e, indicates that the toilet booth TB is unavailable or in an abnormal state. That is, it indicates that the toilet booth TB corresponding to display units 20d and 20e is unavailable. The second display mode SD to which the third display modes TD21 and TD22 are not assigned, i.e., the display mode such as display unit 20b, indicates that the toilet booth TB is full. The first display mode FD, i.e., the display mode such as display unit 20a, indicates that the toilet booth TB is available for use.

[0137] The display setting unit 127 sets multiple display modes for the display unit 20 provided in each of the multiple toilet booths TB, based on the cleaning management status of the cleaning management unit 126, to indicate the status of the toilet booth TB. For example, the display setting unit 127 sets the display modes so that the display mode indicating the status of the toilet booth TB to be cleaned changes depending on whether or not the cleaning management unit 126 has notified the completion of the cleaning work.

[0138] Specifically, the display setting unit 127 is configured to display the display mode of the display unit 20d indicating that the toilet booth TB is unavailable if the cleaning work is not yet completed, and to display the display mode of the display unit 20c indicating that the toilet booth TB is recommended for use if the cleaning work is completed.

[0139] Next, another example of setting the display mode in the display setting unit 127 will be described. Figure 14 is a diagram showing an example of display settings according to the first embodiment. For example, the display setting unit 127 obtains the administrator's settings using the content CT1 in Figure 14. The content CT1 includes an image of the display mode, usage information that is the condition for display in the corresponding display mode, a value (threshold, etc.) used in that condition, and an item that specifies whether that condition is enabled or disabled.

[0140] For example, an administrator configures settings by entering information into content CT1 displayed on an external configuration terminal used by the administrator for various settings. In this case, the administrator enables a condition by checking the checkbox corresponding to the condition they want to use. The administrator also disables a condition by unchecking the checkbox corresponding to the condition they do not want to use. Furthermore, the administrator sets detailed values ​​(thresholds, etc.) for the conditions to be used by entering setting values.

[0141] The display setting unit 127 displays the information in the corresponding display mode if the conditions corresponding to the items checked by the administrator in the checkboxes are met. Note that the settings shown in Figure 14 are merely examples, and the display setting unit 127 may configure the information in any manner if the desired configuration is possible. For example, the display setting unit 127 may process the information based on the pre-configured initial settings (default). In this case, if the administrator changes the initial settings, for example, the display setting unit 127 will process the information based on the changed settings.

[0142] The display control unit 128 controls multiple display modes based on the setting conditions of the display setting unit 127. The display control unit 128 controls the display of the display unit 20 based on a first display mode and a second display mode that indicate whether the toilet booth TB is available or full, and at least one third display mode that is assigned to the first display mode or the second display mode.

[0143] The display control unit 128 performs a determination process. The display control unit 128 performs a determination process using various information stored in the storage unit 140. The display control unit 128 performs a determination process using various information acquired by the acquisition unit 123. The display control unit 128 performs a determination process using various calculated values ​​(information). The display control unit 128 performs a determination process using threshold values ​​stored in the display setting information storage unit 145.

[0144] The display control unit 128 generates various types of information used for determination. The display control unit 128 performs generation processing. The display control unit 128 performs generation processing using the various types of information stored in the storage unit 140. The display control unit 128 performs generation processing using the various types of information acquired by the acquisition unit 123.

[0145] The display control unit 128 controls the display of the display unit 20 by having the communication unit 110 transmit control information that controls the display of the display unit 20 to the display unit 20. The display control unit 128 controls the display of the display unit 20 by having the communication unit 110 transmit control information that controls the display of the display unit 20. When the display control unit 128 determines that the display by the display unit 20 has ended, it generates control information (display instruction information) that instructs the display to be turned off, and instructs the communication unit 110 to transmit the generated control information (display instruction information) to the display unit 20.

[0146] The display control unit 128 generates various control information, such as a signal (display update signal) to update the display of the display unit 20. The display control unit 128 generates control information that instructs the display unit 20 to display or not display. The display control unit 128 generates control information that includes information specifying the display mode for the display unit 20. The display control unit 128 generates control information that includes information specifying either a first display mode or a second display mode to be displayed on the display unit 20. For example, the display control unit 128 generates control information that includes information specifying the color to be displayed on the display unit 20. For example, the display control unit 128 generates control information that includes information specifying the color corresponding to either a first display mode or a second display mode.

[0147] The display control unit 128 generates control information that includes information specifying a third display mode to be displayed on the display unit 20. For example, the display control unit 128 generates control information that includes information specifying a visual symbol to be displayed on the display unit 20. The display control unit 128 generates control information that includes information specifying a pictogram to be displayed on the display unit 20.

[0148] For example, if the display control unit 128 determines that the display unit 20 should display the first display mode, it generates control information (display instruction information) that instructs the display to be in the first display mode, and instructs the communication unit 110 to transmit the generated control information (display instruction information) to the display unit 20. For example, if the display control unit 128 determines that the display unit 20 should display both the first and third display modes, it generates control information (display instruction information) that instructs the display to be in the first and third display modes, and instructs the communication unit 110 to transmit the generated control information (display instruction information) to the display unit 20.

[0149] For example, if the display control unit 128 determines that the display unit 20 should display the second display mode, it generates control information (display instruction information) that instructs the display to be in the second display mode, and instructs the communication unit 110 to transmit the generated control information (display instruction information) to the display unit 20. For example, if the display control unit 128 determines that the display unit 20 should display both the second and third display modes, it generates control information (display instruction information) that instructs the display to be in the second and third display modes, and instructs the communication unit 110 to transmit the generated control information (display instruction information) to the display unit 20.

[0150] When the display control unit 128 determines that the display by the display unit 20 is finished, it generates control information (display instruction information) to instruct the display to be turned off, and instructs the communication unit 110 to transmit the generated control information (display instruction information) to the display unit 20.

[0151] For example, the display control unit 128 instructs the display unit 20 to switch the display mode assigned to the toilet booth TB according to the detection result of the detection unit 30. For example, the display control unit 128 instructs the display unit 20 to change the display mode assigned to the toilet booth TB by instructing the communication unit 110 to send control information to the display unit 20 when the detection unit 30 detects that the user has left the toilet booth TB. For example, the display control unit 133 instructs the display unit 20 to change the display mode assigned to the toilet booth TB by instructing the communication unit 110 to send control information to the display unit 20 when the detection unit 30 detects that the user has entered the toilet booth TB.

[0152] For example, the display control unit 128 instructs the display unit 20 to switch the display mode assigned to the toilet booth TB in accordance with notification information from the cleaning management unit 126. For example, the display control unit 128 instructs the display unit 20 to change the display mode assigned to the toilet booth TB by instructing the communication unit 110 to send control information to the display unit 20 when the cleaning management unit 126 notifies it that the cleaning work on the toilet booth TB has been completed.

[0153] The display control unit 128 determines that it will not change the display mode assigned to the toilet booth TB until the usage status of the toilet booth TB changes. For example, when the usage status of the toilet booth TB changes from occupied (full) to unused (vacant), the display control unit 128 instructs the communication unit 110 to send control information to the display unit 20, thereby instructing the display unit 20 to change the display mode. For example, when the usage status of the toilet booth TB changes from unused (vacant) to occupied (full), the display control unit 128 instructs the communication unit 110 to send control information to the display unit 20, thereby instructing the display unit 20 to change the display mode.

[0154] The display control unit 128 executes a process to generate content related to the control of the toilet cleaning plan management system 1. The display control unit 128 generates content to be provided to the display unit 20. For example, the display control unit 128 generates content for receiving input of cleaning-related information from cleaning staff. For example, the display control unit 128 generates content using various technologies such as Java (registered trademark) as appropriate. The display control unit 128 may also generate content based on CSS, JavaScript (registered trademark), or HTML format. Furthermore, for example, the display control unit 128 may generate content in various formats such as JPEG (Joint Photographic Experts Group), GIF (Graphics Interchange Format), or PNG (Portable Network Graphics).

[0155] Here, specific examples of display modes displayed by the processing of the display control unit 128 will be described. Figure 15 is a diagram showing examples of the first and third display modes according to the first embodiment. Figure 16 is a diagram showing examples of the second and third display modes according to the first embodiment.

[0156] Figure 15 shows the display mode of the display unit 20c in Figure 13, as displayed by the display unit 20 located in the toilet booth TB. In this way, the display control unit 128 causes the display unit 20 located in the toilet booth TB to display the first display mode FD to which the third display mode TD11 is assigned, so that the user can intuitively understand that the toilet booth TB is in a suitable state for use, thereby increasing the likelihood that the user will use the toilet booth TB.

[0157] Furthermore, Figure 16 shows the display mode of the display unit 20d in Figure 13, as displayed by the display unit 20 located in the toilet booth TB. In this way, the display control unit 128 causes the display unit 20 located in the toilet booth TB to display the second display mode SD to which the third display mode TD21 is assigned. As shown in Figure 16, even when the door is open, the user can intuitively understand that the toilet booth TB is not in a suitable state for use, thus reducing the likelihood that the user will use the toilet booth TB.

[0158] In the example above, a pictogram was shown as an example of the third display mode TD, but the third display mode TD may also be a change in the display mode, such as the brightness of the light. In this case, for example, the third display mode TD may be a mode that changes the brightness of the first display mode FD. For example, the third display mode TD may be a mode that repeatedly displays and hides the first display mode FD (flashing). For example, the third display mode TD may be a mode that changes the brightness of the second display mode SD. For example, the third display mode TD may be a mode that repeatedly displays and hides the second display mode SD (flashing).

[0159] (Example of processing flow) From here, we will explain the flow of various processes based on each flowchart. First, we will explain the process flow of the management terminal 100 creating a cleaning plan. Figure 17 is a flowchart of an example of the procedure of the process executed by the management terminal according to the first embodiment. Note that each step in the flowchart shown in Figure 17 can be executed in a different order, and there may be additional processes or processes that are omitted.

[0160] The management terminal 100 refers to the cleaning items of the toilet space 2 to be cleaned (S101). The management terminal 100 then refers to the cleaning skill classification of the cleaning staff (S102). The management terminal 100 then creates a cleaning plan assigning cleaning staff with the corresponding skill classification to each cleaning item (S103), and the process ends.

[0161] Next, the processing flow of the process by which the management terminal 100 determines whether cleaning is necessary will be described. Figure 18 is a flowchart showing an example of the procedure of the process executed by the management terminal according to the first embodiment. Note that each step in the flowchart shown in Figure 18 can be executed in a different order, and additional or omitted processes may be included.

[0162] The management terminal 100 determines whether the current time corresponds to the timing for determining whether cleaning is necessary (S201). If it does correspond to the timing for determining whether cleaning is necessary (S201; Yes), the management terminal 100 determines whether the item to be cleaned meets the criteria for determining whether cleaning is necessary (S202). On the other hand, if it does not correspond to the timing for determining whether cleaning is necessary (S201; No), the management terminal 100 waits until the current time corresponds to the timing for determining whether cleaning is necessary.

[0163] Then, if the item to be cleaned meets the criteria for determining whether cleaning is necessary (S202; Yes), the management terminal 100 determines that the item needs to be cleaned (S203). On the other hand, if the item to be cleaned does not meet the criteria for determining whether cleaning is necessary (S202; No), the management terminal 100 determines that the item does not need to be cleaned (S204). Then, after processing S203 or S204, the management terminal 100 notifies the cleaning terminal 300 whether cleaning is necessary or not (S205), and the process ends.

[0164] Next, the processing flow for the management terminal 100 changing the display mode of the display unit 20 upon receiving a cleaning completion input will be described. Figure 19 is a flowchart showing an example of the procedure for processing performed by the management terminal according to the first embodiment. Note that each step in the flowchart shown in Figure 19 can be executed in a different order, and additional or omitted processes may be included.

[0165] The management terminal 100 determines whether or not it has received an input indicating the completion of the cleaning work (S301). If it has received an input indicating the completion of the cleaning work (S301; Yes), the management terminal 100 determines that the target toilet booth TB is in a state where it is recommended for use (S302). On the other hand, if it has not received an input indicating the completion of the cleaning work (S301; No), the management terminal 100 waits until it receives an input indicating the completion of the cleaning work.

[0166] Then, the management terminal 100 transmits control information to the display unit 20 of the target toilet booth TB to display the first display mode and the third display mode indicating a recommendation for use (S303), and the process ends.

[0167] [Second Embodiment] By the way, in the first embodiment described above, we explained the process of creating a cleaning plan based on pre-set cleaning items and cleaning personnel information for the toilet space 2 to be cleaned, but the system is not limited to this. For example, the toilet cleaning plan management system 1 described below can update a cleaning plan that has been created once to a cleaning plan based on the updated information in response to changes in cleaning frequency or cleaning personnel information.

[0168] (Processing details of the toilet cleaning plan management system) The following describes the processing according to the second embodiment of the toilet cleaning plan management system 1 described above. Figure 20 is a diagram illustrating the processing content of the toilet cleaning plan management system according to the second embodiment. The toilet cleaning plan management system 1 according to the second embodiment includes a management terminal 100 that manages the cleaning plan of a toilet space 2 in which a plurality of toilet booths TB are set, and an output device that outputs the cleaning plan managed by the management terminal 100. The toilet cleaning plan management system 1 creates a cleaning plan for the toilet space based on a plurality of cleaning items that divide a plurality of cleaning tasks in the toilet space 2, and sets a first cleaning plan to clean the toilet space 2 based on at least one of the plurality of cleaning items. If at least a part of the first cleaning plan is changed, it is possible to change to a second cleaning plan to clean the toilet space 2.

[0169] For example, the toilet cleaning plan management system 1 has a management terminal 100 and an output device 200, as shown in Figure 20. First, the management terminal 100 creates a first cleaning plan based on pre-set information, which involves four cleaning operations in the first and second weeks of July. The toilet cleaning plan management system 1 then receives a change in setting information from the administrator, such as changing the cleaning frequency from four times a week to five times a week. Based on the change in setting information, the toilet cleaning plan management system 1 then creates a second cleaning plan that adds a fifth cleaning operation to the first and second weeks of July.

[0170] This allows the toilet cleaning plan management system 1 to create a second cleaning plan based on the changed settings when the settings information of the already created first cleaning plan is modified. Therefore, the toilet cleaning plan management system 1 can appropriately update the toilet cleaning plan in response to changes in the setting conditions.

[0171] (Functional configuration of the management terminal) The functional configuration of the management terminal will be described below with reference to Figure 21. Figure 21 is a block diagram showing an example of the configuration of a management terminal according to the second embodiment. As shown in Figure 21, the management terminal 100B according to the second embodiment differs from the management terminal 100A according to the first embodiment in that it has a condition setting unit 129, a person in charge setting unit 130, and a cleaning time estimation unit 131. The functional configuration units that perform processing different from that of the first embodiment 1 will be described in order below.

[0172] The cleaning plan creation unit 122 sets a first cleaning plan for cleaning the toilet space 2 based on at least one cleaning item from among several cleaning items. If at least a part of the first cleaning plan is changed, it can change to a second cleaning plan for cleaning the toilet space 2. Here, the first cleaning plan is the pre-change plan created before the conditions for creating the cleaning plan were changed, and the second cleaning plan is the post-change plan created after the conditions for creating the cleaning plan were changed.

[0173] For example, if the cleaning conditions assigned to the first cleaning plan are changed by the condition setting unit 129 (described later), the cleaning plan creation unit 122 will change the cleaning plan to the second cleaning plan based on the changed cleaning conditions.

[0174] Here, we will explain the process when cleaning conditions are changed with specific examples. Figure 22 is a diagram illustrating the process of creating a second cleaning plan due to a change in cleaning conditions according to the second embodiment. Figure 22 shows an example in which a cleaning plan is created in which cleaning work is added due to changes in the number of users and cleaning frequency for the 1F men's restroom, 1F women's restroom, 2F men's restroom, and 2F women's restroom.

[0175] As shown in Figure 22(1), the condition setting unit 129, described later, sets the number of users to 500 people / day and the cleaning frequency to 3 times a week for the men's and women's restrooms on the 1st floor. The condition setting unit 129 also sets the number of users to 400 people / day and the cleaning frequency to 3 times a week for the men's and women's restrooms on the 2nd floor.

[0176] Then, as shown in Figure 22(2), the cleaning plan creation unit 122 can create a cleaning plan in which the cleaning frequency for the first week of July is changed to three times a week by adding a cleaning operation on July 5 (Fri) to the twice-weekly cleaning operations from July 1 (Mon) to July 4 (Thu) for the 1F men's restroom, 1F women's restroom, 2F men's restroom, and 2F women's restroom, from July 1 (Mon) to July 4 (Thu).

[0177] Furthermore, the cleaning plan creation unit 122 creates a first cleaning plan based on the information acquired by the acquisition unit 123. For example, the cleaning plan creation unit 122 creates a first cleaning plan for a toilet space 2 that is determined to require cleaning based on information acquired by the acquisition unit 123, which indicates that the number of users detected by a human body detection sensor installed at the entrance of the toilet space 2 is 150 or more.

[0178] Furthermore, the cleaning plan creation unit 122 modifies the second cleaning plan based on the information acquired by the acquisition unit 123. For example, the cleaning plan creation unit 122 modifies the first cleaning plan to the second cleaning plan by using the information on the usage status of the equipment to be cleaned acquired by the acquisition unit 123 to remove cleaning locations that do not need to be cleaned or to add cleaning locations that do not need to be cleaned and are not listed in the first cleaning plan.

[0179] For example, if the cleaning plan creation unit 122 determines that cleaning is unnecessary because the amount of liquid soap acquired by the acquisition unit 123 does not reach the amount requiring replenishment, it changes the first cleaning plan related to item 2 to a second cleaning plan that removes the cleaning work for replenishing the liquid soap.

[0180] Here, both the first cleaning plan and the second cleaning plan created by the cleaning plan creation unit 122 can be manually modified by the administrator or other person, and the cleaning plan creation unit 122 can create a cleaning plan that reflects the modifications.

[0181] Furthermore, if the cleaning items assigned in the first cleaning plan in the cleaning item setting unit 121 are changed, the cleaning plan creation unit 122 will change the second cleaning plan based on the changed cleaning items. For example, if the cleaning items assigned in the cleaning item setting unit 121 are changed after the first cleaning plan has been created, the cleaning plan creation unit 122 will create a second cleaning plan with the changed cleaning items. The changed cleaning items will be stored in the cleaning item information storage unit 141 by the cleaning item setting unit 121.

[0182] Here, we will explain the process when cleaning items are changed with specific examples. Figure 23 is a diagram showing an example of a change in cleaning items according to the second embodiment. Figure 23 shows an example where some of the cleaning items shown in Figure 7 are changed to the other set of cleaning items.

[0183] As shown in Figure 23, some of the cleaning tasks assigned to either item 1 or item 2 in the first cleaning plan in Figure 23(1) have been changed to the other cleaning item in the second cleaning plan in Figure 23(2). Specifically, garbage collection has been changed from item 1 to item 2, and paper replenishment has been changed from item 2 to item 1. This is a change in cleaning items due to reasons such as the need to increase the frequency of garbage collection due to an increase in the number of users, or the need to reduce the frequency of paper replenishment due to an increase in the amount of paper stock.

[0184] The cleaning plan creation unit 122 can create a second cleaning plan that adjusts cleaning times and other details according to the revised cleaning item assignments shown in Figure 23(2).

[0185] Furthermore, the cleaning plan creation unit 122 creates a cleaning plan by associating cleaning items with cleaning personnel based on the cleaning personnel information set by the personnel setting unit 130, which will be described later. For example, the cleaning plan creation unit 122 uses the cleaning personnel information stored in the cleaning personnel information storage unit 143 by the personnel setting unit 130, which will be described later, to assign cleaning personnel classified into cleaning skill categories corresponding to the first and second items of the toilet space 2 to be cleaned, and creates a cleaning plan.

[0186] For example, if the cleaning plan creation department 122 has set "regular employee" as the cleaning skill category corresponding to the first item group (see Figure 8(2)), it will create the cleaning plan for the first item by assigning either "Sato" or "Takahashi," who are cleaning staff members with a contract as regular employees, according to the toilet space 2 to be cleaned.

[0187] Furthermore, if the cleaning staff assigned in the first cleaning plan is changed by the staff assignment unit 130 (described later), the cleaning plan creation unit 122 will change the second cleaning plan based on the changed cleaning staff information. For example, if the cleaning staff listed in the first cleaning plan is changed by the staff assignment unit 130 (described later), the cleaning plan creation unit 122 will create the second cleaning plan with the changed cleaning staff settings. Specifically, if the cleaning staff assigned in the first cleaning plan is unable to perform the cleaning work and a change to another cleaning staff member is set, the cleaning plan creation unit 122 will create the second cleaning plan by comprehensively considering the available working hours and cleaning skill category of the new cleaning staff member, as well as the coordination with other cleaning tasks scheduled at different times.

[0188] For example, if cleaning staff member "Sato" listed in the first cleaning plan is unable to perform the cleaning work, the cleaning plan creation department 122 identifies cleaning staff member "Watanabe" who is classified in the same skill category as "Sato" and corresponds to the same first item group, and who can take over the cleaning work time assigned to "Sato." The department then creates a second cleaning plan by changing "Sato" in the first cleaning plan to "Watanabe."

[0189] The condition setting unit 129 sets cleaning conditions for cleaning items. For example, the condition setting unit 129 sets the cleaning conditions to be set for each cleaning item set by the cleaning item setting unit 121. Here, the cleaning conditions include information about the conditions for creating a cleaning plan, such as the cleaning frequency, cleaning time, and cleaning quality for each cleaning item.

[0190] For example, the condition setting unit 129 stores setting conditions for the first item of the toilet space 2 to be cleaned, such as cleaning frequency twice and cleaning time of two hours, in association with the first item group in the cleaning item information storage unit 141.

[0191] Furthermore, the condition setting unit 129 can accept changes to the cleaning conditions. For example, after the output of the first plan, the condition setting unit 129 can accept input from the administrator regarding changes to the cleaning conditions and notify the cleaning plan creation unit 122 of the information regarding the changed cleaning conditions.

[0192] For example, the condition setting unit 129 accepts a change in the setting conditions for the first item, such as an increase in the number of users of the toilet space 2 to be cleaned, from a cleaning frequency of 2 times and a cleaning time of 2 hours to a cleaning frequency of 3 times, and stores it in the first item group of the cleaning item information storage unit 141 in association with it.

[0193] The condition setting unit 129 can also display information to assist administrators in changing cleaning conditions. Figure 24 illustrates a specific example of assisting in changing cleaning conditions by predicting the number of uses according to the second embodiment. Figure 24 shows an example of a graph predicting the number of uses for toilets 1 to 4 in the men's restroom on the 2nd floor of Building A, based on past usage information.

[0194] As shown in Figure 24, the condition setting unit 129 refers to the information on the dates on which cleaning work will be carried out as described in the first cleaning plan created by the cleaning plan creation unit 122, and obtains that cleaning work is scheduled to be carried out on July 1st, July 8th, and July 15th for toilets 1 through 4 in the men's restroom on the 2nd floor of Building A. The condition setting unit 129 then obtains the information on the number of times toilets 1 through 4 have been used in a day as detected by the detection unit 30.

[0195] Subsequently, the condition setting unit 129 uses information on the cleaning date and the number of times the toilet to be cleaned is used per day to create a graph showing the cumulative number of uses from one cleaning to the next. Specifically, as shown in Figure 24, the condition setting unit 129 creates a graph showing a straight line representing the cumulative number of toilet uses over the seven days from July 1st, when the cleaning is performed, to July 8th, when the next cleaning is performed. The condition setting unit 129 then displays the usage threshold of 120 times, which has been set in advance by the administrator, as the maximum number of uses that must not be exceeded.

[0196] The condition setting unit 129 creates and displays the graph shown in Figure 24, allowing the administrator to easily understand whether the cleaning frequency of the first and second cleaning plans created by the cleaning plan creation unit 122 exceeds the preset maximum usage threshold, thereby supporting changes to the cleaning conditions.

[0197] The assignment setting unit 130 assigns cleaning personnel to clean the toilet space 2. For example, the assignment setting unit 130 receives pre-selected candidates for cleaning personnel from the administrator for the period covered by the cleaning plan and notifies the cleaning plan creation unit 122. Specifically, for July, which is the month for which the cleaning plan is to be created, the assignment setting unit 130 receives pre-selected candidates for cleaning personnel who can be in charge of the cleaning work and notifies the cleaning plan creation unit 122 to create a cleaning plan using the accepted candidates.

[0198] Furthermore, the assignment setting unit 130 accepts changes to the cleaning staff assigned to the first cleaning plan. For example, after the first plan is output, the assignment setting unit 130 accepts input from the administrator regarding a change in the cleaning staff and notifies the cleaning plan creation unit 122 of information such as the new cleaning staff member, the cleaning tasks subject to the change in cleaning staff member, and the cleaning time.

[0199] For example, if cleaning person "Sato" listed in the first cleaning plan is unable to perform the cleaning work, the cleaning plan creation department 122 will accept the cleaning person "Watanabe" designated by the manager as the replacement cleaning person, and notify the cleaning plan creation department 122 to change "Sato" to "Watanabe" in the first cleaning plan.

[0200] The cleaning time estimation unit 131 estimates the cleaning time required for each cleaning item. For example, the cleaning time estimation unit 131 calculates the cleaning time for each cleaning item using parameters for which cleaning time estimates have been set in advance for each of the first and second items. Here, the cleaning time estimation unit 131's calculation process for cleaning time will be explained with a specific example. Figure 25 is a diagram illustrating the cleaning time estimation process in the second embodiment.

[0201] As shown in Figure 25(1), the cleaning time estimation unit 131 receives the first item's estimated cleaning time of 60 minutes and the second item's estimated cleaning time of 15 minutes from the administrator's input. Then, as shown in Figure 25(2), the cleaning time estimation unit 131 calculates the estimated cleaning time per month of 36 hours, which is the product of the received single estimated cleaning time and the number of cleaning sessions scheduled for July.

[0202] Furthermore, as shown in Figure 25(2), the cleaning time estimation unit 131 can calculate a -10% decrease compared to the same month of the previous year and a -3% decrease compared to the previous month for the estimated cleaning time of 36 hours per month. Therefore, the estimated cleaning time can be made known to the manager when creating the first cleaning plan, serving as a basis for changing conditions for creating the second cleaning plan.

[0203] Furthermore, the cleaning time estimation unit 131 calculates the cleaning time based on the cleaning start and cleaning completion inputs. For example, the cleaning time estimation unit 131 refers to the time information of when it received the cleaning start input and cleaning completion input transmitted from the cleaning terminal 300, and calculates the difference between the time of the cleaning start input and the time of the cleaning completion input as the cleaning time.

[0204] Here, we will explain the cleaning time required calculated by the cleaning time estimation unit 131 with a specific example. Figure 26 is a diagram showing an example of displaying comparative information between the cleaning time required and the estimated cleaning time according to the second embodiment. In Figure 26, for the first item of the men's restroom on the 1st floor of Building A, an example is shown where the cleaning work history for June, the cleaning plan, the average cleaning time required and the estimated cleaning time are displayed.

[0205] As shown in Figure 26, the cleaning time estimation unit 131 calculates an average cleaning time of 50 minutes for cleaning work from Monday, June 3 to Wednesday, June 26. The cleaning time estimation unit 131 then notifies the cleaning plan creation unit 122 of the calculated average cleaning time of 50 minutes, and the cleaning plan creation unit 122 creates a cleaning plan that includes the average cleaning time of 50 minutes and the estimated cleaning time of 60 minutes set in the first item. Subsequently, the cleaning plan creation unit 122 transmits the created cleaning plan to the output device 200, and the output device 200, upon receiving the cleaning plan, outputs a cleaning plan that includes the cleaning time and the estimated cleaning time.

[0206] Furthermore, the cleaning time estimation unit 131 updates the information used to calculate the estimated cleaning time based on the actual cleaning time required. For example, if the cleaning time required calculated for a single cleaning operation deviates from the set estimated cleaning time, the cleaning time estimation unit 131 updates the parameters used to calculate the estimated cleaning time so that the calculated estimated cleaning time approaches the actual cleaning time required.

[0207] Specifically, the cleaning time estimation unit 131 updates the parameters so that the estimated cleaning time for the first item in the next cleaning plan is close to the actual cleaning time (for example, 55 minutes) if, for example, the currently set estimated cleaning time for the first item is 60 minutes and the actual calculated cleaning time is 50 minutes.

[0208] Furthermore, the cleaning time used by the cleaning time estimation unit 131 to update the parameters is not particularly limited. For example, the parameters can be updated each time to approximate the most recent cleaning time, or the parameters can be updated for each cleaning staff member using the cleaning time for each cleaning staff member.

[0209] Furthermore, the cleaning time estimation unit 131 calculates the estimated cleaning time for the first cleaning plan and the second cleaning plan. For example, for each of the first cleaning plan and the second cleaning plan created by the cleaning plan creation unit 122, the cleaning time estimation unit 131 calculates the total estimated cleaning time for the period covered by the cleaning plan creation and notifies the cleaning plan creation unit 122.

[0210] The cleaning plan creation unit 122 then creates a first cleaning plan and a second cleaning plan, each containing the notified estimated cleaning time. After creating these plans, it displays them side-by-side for comparison, allowing the administrator to easily understand the comparison results of the estimated cleaning time before and after the change in the setting conditions.

[0211] (Example of processing flow) From here, we will explain the flow of various processes based on each flowchart. First, we will explain the process flow of the management terminal 100 creating the second cleaning plan with the information after the setting change. Figure 27 is a flowchart of an example of the procedure of the process executed by the management terminal according to the second embodiment. Note that each step in the flowchart shown in Figure 17 can be executed in a different order, and there may be additional processes or omitted processes.

[0212] The management terminal 100 creates a first cleaning plan for each of the cleaning items set for the toilet space 2 to be cleaned (S401). Then, the management terminal 100 determines whether or not it has received a change in the setting information for the cleaning items, etc. (S402). If it has received a change in the setting information for the cleaning items, etc. (S402; Yes), the management terminal 100 creates a second cleaning plan based on the information received (S403) and terminates the process. On the other hand, if it has not received a change in the setting information for the cleaning items, etc. (S402; No), the management terminal 100 terminates the process.

[0213] Next, we will describe the processing flow of the process by which the management terminal 100 updates the parameters used to calculate the estimated cleaning time. Figure 28 is a flowchart showing an example of the processing procedure performed by the management terminal according to the second embodiment. Note that each step in the flowchart shown in Figure 28 can be executed in a different order, and additional or omitted processes may be included.

[0214] The management terminal 100 obtains the cleaning time from the specified location and period information of past cleaning work (S501). Then, the management terminal 100 obtains statistical information on the cleaning time from the acquired data (S502). Finally, the management terminal 100 updates the parameters for calculating the estimated cleaning time (S503) and ends the process.
