Description

[Technical Field]

[0001] The present disclosure relates to a method for managing toilets by a server based on toilet usage, and more particularly to a toilet management method that uses machine learning in a server to grasp the state of the toilet from the number of users who use the toilet and the frequency of toilet usage, and notifies users and cleaning staff of the grasped state of the toilet, thereby encouraging them to use clean toilets and maintaining the cleanliness of the toilets. [Background technology]

[0002] There are toilets in the surrounding area that are shared by various people in buildings, construction sites, subway stations, bus stops, parks, etc.

[0003] Maintaining these toilets requires a lot of manpower and time.

[0004] Furthermore, unless you live in the area or visit it frequently, it is not easy to know where the toilets are, and even if you do find one, you may have limited access if there are a lot of people there.

[0005] Furthermore, despite investing a lot of manpower and time, managing toilets that are scattered in various places is a difficult task.

[0006] Therefore, research continues into how to efficiently manage restrooms to minimize wasted manpower and time while still allowing users to use clean, currently unoccupied restrooms. Summary of the Invention [Problem to be solved by the invention]

[0007] The object of the present invention is to provide a method for managing toilets based on toilet usage, which involves installing sensors in toilets used by many people, storing information such as user entry and exit information, dwell time, and complaint information via the sensors, and using machine learning based on the stored data to determine toilet paper usage, hygiene level, etc. in the toilet, and informing users and managers of the determined toilet condition, thereby maintaining the cleanliness of the toilets without wasting manpower and enabling clean and usable toilets to be quickly found and used. [Means for solving the problem]

[0008] One embodiment of the present disclosure for solving the above-mentioned problems is a method in which a server manages toilets based on user information, and includes an information acquisition step of acquiring user information through at least one sensor installed in the toilet, a toilet status transmission step of determining the status of the toilet based on the user information and transmitting the information to at least one terminal, and a cleaning request step of requesting cleaning from a cleaning staff terminal according to the status of the toilet determined in the toilet status transmission step.

[0009] After the toilet status transmitting step, if the toilet has been vacant for a certain period of time or more based on the toilet usage amount, the method may further include a toilet disinfecting step of disinfecting the toilet using a disinfecting device installed in the toilet.

[0010] After the cleaning request step, if the cleaning person has completed cleaning and the state of the toilet is changed to a clean state, the method may further include a toilet state change receiving step of receiving the change.

[0011] The method may further include a health assessment step of assessing the user as having an abnormal health condition if the user remains in a predetermined area in the restroom for a certain period of time or more.

[0012] The cleaning instruction step may include a primary instruction step of issuing a cleaning instruction to the cleaning staff terminal when the number of users who have used the toilet is equal to or greater than a predetermined number.

[0013] The cleaning instruction step may further include a secondary instruction step of instructing cleaning of the toilet based on the number of users, the length of stay, and complaints if the number of users using the toilet is below a certain number or if the number of times the private room has been used is above a certain number.

[0014] The state of the toilet may be provided for each individual stall, and the cleaning instruction step may further include a tertiary instruction step of instructing cleaning of the toilet based on the dwell time using the toilet.

[0015] The third instruction step, when the number of times the private room has been used is equal to or less than a certain number of times,

[0016]

number

[0017] (Where, (CRT = required dwell time for cleaning), (ACSD = cumulative dwell time * day)) If the ACSD value is greater than the CRT value, a cleaning instruction can be sent to the manager terminal.

[0018] After the toilet status sending step, if the user requests toilet use confirmation, the method may further include a toilet recommendation step of recommending at least one toilet based on the user's terminal location, and allowing the user to confirm or reserve toilet use of at least one of the recommended toilets. [Effects of the Invention]

[0019] According to one embodiment of the present disclosure, the cleanliness of the toilet can be managed through information on users who use the toilet.

[0020] In addition, the cleanliness of the toilets can be monitored in real time, minimizing wasted manpower if cleaning is not required.

[0021] In addition, by allowing users to check the cleanliness of the toilet and whether it is available for use, unnecessary traffic flow can be minimized. [Brief explanation of the drawings]

Whether such functionality is implemented as hardware or software depends on the particular application and design constraints imposed on the overall system. Skilled artisans can implement the described functionality in various ways for each particular application. However, such implementation decisions should not be interpreted as causing a departure from the scope of the present disclosure.

[0029] The description of the presented embodiments is provided to enable one of ordinary skill in the art to utilize or practice the present disclosure. Various modifications to these embodiments will be apparent to those of ordinary skill in the art to which the present disclosure pertains. The generic principles defined herein may be applied to other embodiments without departing from the scope of the present disclosure. Thus, the present invention is not limited to the embodiments shown herein. The present invention is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0030] First, the terms used in this disclosure will be explained.

[0031] 1. User information: refers to information about users of a restroom. For example, user information may include, but is not limited to, information about restroom visits, visits to specific restroom stalls, amount of use, time spent in the restroom, and number of users using the restroom. In this case, user information may be provided in an anonymized form. Anonymization here means that the user's identity is not known. This is because restrooms are special spaces where personal privacy must be respected, and anonymized information may be used to ensure smooth operation without privacy violations.

[0032] 2. Dwell time: It can be the time from the moment a person using the toilet enters through the entrance to the moment they exit.

[0033] 3. Toilet stall dwell time: This can be the time from the moment of entering a stall installed in a designated area where the toilet bowl is located to the moment of exiting.

[0034] 4. Number of times a cubicle is used: This can be the number of times a user repeatedly enters and exits a cubicle installed in a predetermined area where a toilet bowl is located.

[0035] 5. Machine Learning: This field studies algorithms that automatically learn rules in data without the need to program each rule individually. It is a core field within the subfield of artificial intelligence that is responsible for software that realizes intelligence. Many machine learning algorithms originate from statistics, and they are developing through the interaction between the fields of statistics and computer science. R, a representative open-source statistical software, has implemented a variety of machine learning algorithms. However, recent developments in machine learning are often based on experience rather than statistics or mathematical theory. The field of computer science is leading this development.

[0036] 6. User terminal: A terminal used by a user who uses or intends to use the toilet.

[0037] The present disclosure will now be described in detail with reference to the drawings.

[0038] FIG. 1 is a flowchart that schematically illustrates steps of a method for a server to manage toilets based on toilet usage in accordance with one embodiment of the present disclosure, and FIG. 2 is a diagram that schematically illustrates an exemplary process of a method for a server to manage toilets based on toilet usage in accordance with one embodiment of the present disclosure.

[0039] The system grasps the cleanliness of the toilet from the number of users using the toilet, the length of time spent there, and user complaints, and notifies the users and cleaning staff of the grasped cleanliness state, so that users can smoothly use a clean toilet without other users, and cleaning staff can check the state of the toilet in real time and clean while minimizing wasted manpower and time.

[0040] This allows for efficient management of the toilets and smooth use of the toilets.

[0041] According to one embodiment of the present disclosure, a method for a server to manage a toilet based on user information includes an information acquisition step (S100) for acquiring user information through at least one sensor installed in the toilet, a toilet status transmission step (S200) for determining the status of the toilet based on the user information and transmitting the information to at least one terminal, and a cleaning request step (S700) for requesting cleaning from a cleaning staff terminal according to the status of the toilet determined in the toilet status transmission step (S200).

[0042] The user information is collected through sensors and sent to a server where it is stored, and the cleanliness of the toilet can be checked based on the stored data, which can be accurately determined through machine learning on the server.

[0043] The terminal may include at least one of a user terminal and a cleaning staff terminal.

[0044] Data can be sent and received via the user terminal and the cleaning staff terminal.

[0045] A detailed explanation is provided below.

[0046] At least one sensor may be installed in the restroom. Examples of such sensors include a ToF (Time for Flight) sensor, a thermal imaging sensor, and a motion sensor that detects user movement. Here, a ToF sensor is a sensor that calculates distance by measuring the time it takes for light to be reflected from an object. Specifically, the sensor can calculate distance by shining a strong light onto an object and detecting the light reflected from the object. The advantages of a ToF sensor include excellent distance resolution, the ability to accurately detect objects in a short time, relative low cost compared to other scanning sensors, and the ability to perform highly accurate measurements over long distances due to the use of a laser.

[0047] In addition, the sensors can be installed at the entrance, the innermost ceiling of the toilet, the sink, the urinal and toilet compartments, etc., thereby making it possible to accurately grasp the location and number of each of multiple users.

[0048] In addition, a QR code is attached to each section (toilet stall), and when a user scans the QR code with their device, they can raise concerns about the state of the toilet.

[0049] As mentioned above, the server can use machine learning to learn already stored user information to verify the cleanliness of the restroom.

[0050] For example, local park toilets have a high number of park visitors per day, and since the majority of users visit the toilet while walking around the park, they are more likely to lose dirt stuck to their shoes, so they take less time to stay clean than other local toilets.

[0051] The user information may include at least one of the number of users using the restroom, the length of time they stay there, their route of travel, and their behavioral patterns.

[0052] The state of the toilet can be determined from the user information. For example, if 30 or more people enter the toilet, the hygiene information can be decreased. The hygiene information can be divided into several stages. The hygiene levels can be divided into three stages: clean level 3 → clean level 2 → clean level 1 → dirty level 1 → dirty level 2 → dirty level 3. These levels can be decreased by one stage for every 30 people.

[0053] In addition, the number of users can be accurately estimated through the user information, and it can be determined that consumables such as toilet paper and soap will be consumed according to the estimated number of users, and they can be included in the cleanliness stage.

[0054] The toilet status determined in the toilet status transmission step (S200) is stored in a server, and the stored data can be transmitted to the user terminal and the cleaning staff terminal. The transmitted data can be checked by the user before and after using the toilet to determine whether the toilet is in use or clean, thereby enabling smooth use of the toilet.

[0055] In addition, the cleaning staff terminal can check the state of the toilets even without a cleaning request from the server, and can clean toilets that are expected to be in poor cleanliness before a request from the server.

[0056] According to one embodiment of the present disclosure, after the toilet status transmission step (S200), if the user requests toilet usage confirmation, the method may further include a toilet recommendation step (S400) of recommending at least one toilet based on the location of the user's terminal, and allowing the user to confirm or reserve the use of at least one of the recommended toilets, and a toilet disinfection step (S500) of disinfecting the toilet using a disinfection device installed in the toilet if the toilet has been vacant for a certain period of time or more based on the toilet usage amount.

[0057] The toilet recommendation step (S400) and the toilet disinfection step (S500) are steps performed after the toilet status transmission step (S200), and can be performed before or after the cleaning request step (S700).

[0058] The toilet recommendation step (S400) is performed before the user uses the toilet to ensure smooth use of the toilet.

[0059] For example, if the user is in the middle of a park and wants to use a restroom but cannot find one, the user may request the location of the restroom from the server. In response to the request, the server may transmit to the user a list of nearby restrooms in order of closest proximity based on the location of the user's device. The user, having received information about nearby restrooms, can select one and use it. In this case, the information about the restroom may include information about the state of the restroom, including at least one of the location of the restroom, the current use status of the toilet bowl in the restroom, and the current cleanliness status. This allows the user to find and visit a clean and available restroom based on the current use status and cleanliness status of the restroom.

[0060] As another example, the user may want to know the status of the toilet for cleaning. Depending on the status of the toilet known in the toilet recommendation step (S400), the user may decide whether or not the toilet needs to be cleaned and may determine the cleaning cycle of the toilet.

[0061] The toilet disinfection step (S500) may disinfect the toilet using a disinfection device installed in at least one of the sensors, or may utilize the time when the toilet is vacant for a long period of time.

[0062] For example, since disinfection may take more than an hour, the time when there are few people may be identified from the user information and disinfection may be performed during the identified time period. Disinfection has the effect of increasing the time the toilet can be kept clean. The time period when there are few people may be identified from the change in the amount of toilet usage in the user information.

[0063] Conversely, when the user visits the toilet, music can be played through a speaker installed in at least one of the sensors. Playing music in the toilet can increase the cleanliness of the toilet and encourage users to use the toilet cleanly.

[0064] According to one embodiment of the present disclosure, after the cleaning request step (S700), if the cleaning person completes cleaning and changes the state of the toilet to a clean state, a toilet state change receiving step (S600) may be further included.

[0065] For example, the server sends a cleaning request to the cleaner's terminal according to the toilet's condition, and the cleaner can clean the toilet after confirming the request. After cleaning is completed, the cleaner can adjust the toilet's cleanliness level and enter the cleaning date. This allows the user to accurately track the time and cleanliness of the toilet.

[0066] The toilet status change receiving step (S600) may be performed regardless of the order after the information obtaining step (S100).

[0067] According to an embodiment of the present disclosure, the method may further include a complaint receiving step (S300) of receiving a complaint filed by the user regarding insufficiencies after using the toilet.

[0068] For example, if a user finds that the cleanliness of the toilet is different from what they could see on the user terminal, or if an unexpected problem occurs (such as the toilet door being left open, resulting in bird or cat droppings), they can file a complaint. The user can easily and accurately input which toilet and stall number the complaint is from via a QR code.

[0069] The complaint receiving step (S300) may be a step that is performed regardless of the order after the information obtaining step (S100).

[0070] According to an embodiment of the present disclosure, the method may further include a health assessment step of assessing the user as having an abnormal health condition if the user remains in a predetermined area in the toilet for a certain period of time or more.

[0071] For example, if the user enters the restroom to relieve themselves but collapses due to health reasons, and they remain in the same place for a period of time that would be considered sufficient to relieve themselves, the server can identify the user as having an unhealthy condition and contact a nearby hospital, police station, fire station, etc.

[0072] The health assessment step may be performed regardless of the order after the information acquisition step (S100).

[0073] According to an embodiment of the present disclosure, the method may further include an abnormal behavior discrimination step of discriminating a user who is behaving abnormally in the toilet.

[0074] The abnormal behavior determining step can identify abnormal behavior such as secretly installing a camera in the toilet or multiple users fighting, and determine the abnormal behavior.

[0075] If a person behaves abnormally, the server can send a notification to an organization that can directly check the toilet, such as the police station, fire department, or security company.

[0076] The notification can ensure the safety of the toilet.

[0077] According to an embodiment of the present disclosure, the abnormal behavior determining step may further include a cleaning behavior determining step of determining the behavior of a person in charge of cleaning.

[0078] This is to prevent the cleaning action from being classified as abnormal behavior.

[0079] Cleaning staff visit areas that need to be cleaned and replaced, such as toilets, toilet paper, and soap, so their actions can be identified as those of cleaning staff, and unnecessary dispatches can be prevented.

[0080] FIG. 3 is a diagram schematically illustrating an example of a condition for requesting cleaning in a method for managing toilets based on toilet usage by a server according to an embodiment of the present disclosure.

[0081] According to one embodiment of the present disclosure, as shown in FIG. 3, the cleaning instruction step may include a primary instruction step (S710) of issuing a cleaning instruction to the cleaning management terminal if the number of users who have used the toilet is equal to or greater than a certain number.

[0082] For example, if the number of users using the restroom is 100 or more, a cleaning instruction may be issued. This is a request for users to use the entire restroom, and can include users who use only the sink without the toilet bowl.

[0083] This allows the number of users using each stall to be tracked separately through sensors installed in the toilet stalls, and if the number of users tracked is 30 or more, a separate cleaning request can be made for that stall.

[0084] Using this method, each private room can be managed separately, and users can be notified for each private room, allowing for specialized management.

[0085] According to one embodiment of the present disclosure, the cleaning instruction step may further include a secondary instruction step (S720) of instructing to clean the toilet when the number of users who have used the toilet is below a certain number and the number of times the private room has been used is above a certain number.

[0086] When the number of users using the toilet is above a certain number, the toilet is cleaned through a cleaning request. However, when the number of users is below a certain number, the cleaning request is no longer made, but if there are no users who use the toilet continuously, the toilet becomes dirty even when not in use, and therefore cleaning cannot be requested. To prevent this, cleaning can be made to occur even when the number of users is below a certain number.

[0087] For example, if the number of users is below a certain number (100 people), and the number of times a toilet stall is used (the total number of times each stall is used) is 50 or more times, regardless of the number of people, the toilet can be deemed unclean and a cleaning request can be made. This minimizes the number of times cleaning is not performed.

[0088] According to one embodiment of the present disclosure, the status of the toilet is provided for each stall, and the cleaning instruction step may further include a tertiary instruction step (S730) of instructing cleaning of the toilet based on the dwell time using the toilet.

[0089] The state of the toilet refers to the cleanliness of the entire toilet, including the sink, toilet seat, toilet bowl, etc., as well as the state of the toilet including all consumables in the toilet stall and the washbasin.

[0090] Among these, it may be possible to provide each state of the toilet stall separately.

[0091] This allows the cleaning staff to check the overall state of the toilet and the state of each individual room separately, and when cleaning, they can check the rooms with the most users and the rooms that are relatively unclean compared to the other rooms, and pay more attention to cleanliness.

[0092] Furthermore, cleaning of the toilets can be instructed based on the length of time spent using the toilets, that is, the length of time spent by the toilet users in each individual toilet compartment.

[0093] For example, if the toilet has stalls 1 to 5, and stall 1 is used for a time longer than the time required for cleaning, and stalls 2 to 5 are used for a time shorter than the time required for cleaning, then a cleaning instruction may be given to stall 1.

[0094] According to one embodiment of the present disclosure, the third instruction step (S730) includes, when the number of times the private room has been used is equal to or less than a certain number of times:

[0095]

number

[0096] (Where, (CRT = required dwell time for cleaning), (ACSD = cumulative dwell time * day)) If the ACSD value is greater than the CRT value, a cleaning instruction may be sent to the manager terminal.

[0097] The CRT is the cleaning required dwell time, which is the minimum dwell time that requires cleaning for the toilet.

[0098] The staying time is the total time that the user stays in the toilet, and it can be determined that the longer the staying time, the lower the cleanliness of the toilet, which can be used as a criterion for determining whether cleaning is necessary.

[0099] The ACSD is the cumulative dwell time multiplied by the number of days since the last cleaning.

[0100] The cumulative staying time is the total value of the time spent by the user in the toilet, which is the total value of the time spent since the last cleaning date, and the number of days since the last cleaning date is the number of days that have passed since the last cleaning date.

[0101] For a detailed example, see the table below.

[0102] [Table 1]

[0103] As shown in Table 1, if the required cleaning time is 300 minutes and the user's time on the first day of the last cleaning is 30 minutes, then on the first day, 30 minutes is multiplied by 1 day to get a value of 30, on the second day, 70 minutes is multiplied by 2 days to get a value of 140, and on the third day, 100 is multiplied by 3 days to get a value of 300. In this case, the required cleaning time has been met, so the server issues a cleaning request to the cleaning staff terminal.

[0104] The number of times each stall is used may be the number of times each stall located in the toilet has been used, and the third instruction step may be to check the cleanliness of each stall and request cleaning.

[0105] According to an embodiment of the present disclosure, after the third instruction step (S730), if cleaning is required, a notification sending step of sending a notification that cleaning is required may be further included.

[0106] Although cleaning has been requested through the series of steps from the first instruction step (S710) to the third instruction step (S730), if it is determined that further cleaning is necessary, further cleaning can be requested.

[0107] For example, if seven days have passed since the last cleaning, the cleaning staff terminal may be requested to confirm whether cleaning is necessary.

[0108] This can prevent situations where cleaning is not performed.
