A monitoring computer 51 compares the time duration of a non-use state with a second threshold when the non-use state of a specific toilet private room is detected by the door opening/closing sensor 12, and detects the state as a failure of the non-use for a long time when the threshold exceeds the second time duration of the non-use state. The second threshold is changed in the value according to a time zone. The second threshold is set in a shorter time in a crowded time zone, and the second threshold is set in a longer time in the non-crowded time zone.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a maintenance management system for toilets such as stations.

  In the toilets of facilities and buildings used by an unspecified number of people, various maintenance management systems have been proposed for the purpose of alleviating congestion and early detection of abnormal conditions. For example, Patent Document 1 proposes a system in which a sensor is provided in a door of each private room of a toilet and a toilet usage status (used state or non-used state) is determined from sensor data. More specifically, the toilet user is guided to an empty private room, or the toilet private room that has been used or not used for a long time is judged to be in an abnormal state and the toilet manager is notified. Things have been done.

Japanese Patent Laid-Open No. 2017-146813

  The system of Patent Document 1 detects a problem of long-term use or non-use of a toilet private room when the usage time or non-use time of a specific toilet private room exceeds a threshold, and notifies the toilet manager. It has become a thing.

  However, the system of Patent Document 1 is mainly intended to guide a toilet user to an empty toilet room in a building having a plurality of toilets on one floor or a plurality of floors. And in the system of patent document 1 applied to such a building, it is not assumed that a big fluctuation | variation arises in the number of toilet users during the day.

  On the other hand, for example, in a toilet at a station, the number of users of the toilet greatly fluctuates during a day, and there are time zones where the crowd is crowded and times when it is not crowded. For this reason, if the threshold for detecting long-time use or non-use of the toilet is increased, rapid detection cannot be performed in a crowded time zone, while unnecessary detection is performed in a non-crowded time zone if the threshold is shortened. There is a problem that increases.

  The present invention has been made in view of the above problems, and even in a toilet of a facility (for example, a station) where the number of toilet users greatly varies during the day, the toilet private room is used for a long time or not used for a long time. It is an object of the present invention to provide a toilet maintenance management system capable of properly detecting a toilet.

  In order to solve the above-described problems, the toilet maintenance management system of the present invention has a detection sensor that detects the usage status of each toilet room in the toilet, and a non-use state of a specific toilet room is detected by the detection sensor. A control unit that compares the duration of the non-use state with a non-use state detection threshold and detects a non-use defect for a long time when the duration exceeds the non-use state detection threshold. The non-use state detection threshold value is changed according to a time zone.

  According to the above configuration, the duration of non-use state of the toilet room is compared with the threshold for detecting the non-use state, and when the non-use state exceeds the non-use state detection threshold, By detecting it, it becomes possible to take necessary measures for trouble that has not been used for a long time. In addition, the non-use state detection threshold is set to a short time during busy hours so that quick detection can be performed, while the non-use state detection threshold is set to a long time during non-crowded times. Increase in detection can be suppressed.

  In the toilet maintenance management system, the non-use state detection threshold may be automatically updated by machine learning based on detection data of the detection sensor.

  According to said structure, the threshold value for a non-use state detection is automatically updated by machine learning, for example, the time zone when the surrounding environment of the facility (for example, station) to which this system is applied changes and becomes crowded Even if the change occurs, the threshold value for non-use state detection can be quickly changed to an appropriate value in response to the change.

  The toilet maintenance management system of the present invention compares the duration of non-use of a toilet private room with a threshold for detecting the non-use state, and if the non-use state exceeds the non-use state detection threshold, it is not used for a long time. It can be detected as a trouble and can be detected quickly by setting the threshold for non-use state detection to a short time during busy hours, while it is used for non-use state detection during non-crowded times. There is an effect that an increase in unnecessary detection can be suppressed by setting the threshold to a long time.

FIG. 1, showing an embodiment of the present invention, is a diagram showing a basic configuration of a toilet maintenance management system. It is a figure which shows the flow of a process when long-time use of a toilet private room is detected in a toilet maintenance management system. In a toilet maintenance management system, it is a figure which shows the flow of a process when non-use of a toilet private room is detected for a long time.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing a basic configuration of a toilet maintenance management system (hereinafter referred to as the present system) according to the present embodiment.

  This system is generally configured by connecting various sensors provided in the toilet 10 and control panels provided in each toilet facility to a monitoring or management computer via a wireless or wired network. Has been. It is also possible to provide a part of information obtained from this system to a general user as a cloud service.

  Specific examples of various sensors provided in the toilet 10 include a human sensor 11 installed on the ceiling of a toilet entrance passage, a door open / close detection sensor (detection sensor) 12 provided on a door of each toilet private room, and the like. It is done. The human sensor 11 detects the entry / exit of a person to / from the toilet 10 and is used to calculate the toilet entry / exit personnel. The door opening / closing detection sensor 12 detects the open / closed state of the door of each toilet private room and is used to detect the use / non-use state of each toilet private room (used state when the door is closed, non-used state when the door is opened). . Moreover, in a multipurpose toilet, the use / non-use state may be detected by an input / output signal of a control panel (detection sensor) 13 of the multipurpose toilet.

  As each facility for the toilet, a water supply pump chamber 30, a sewage tank 40, and the like can be given. A water storage tank (not shown) and a water supply pump 31 are installed in the water supply pump chamber 30, and the water supply pump 31 is driven to supply water from the storage tank to the toilet 10 as toilet flush water. The control panel 32 in the water supply pump chamber 30 performs water level detection of the water storage tank by the water level sensor 33 and drive control of the water supply pump 31. The sewage tank 40 temporarily stores sewage discharged from the toilet 10, and a drainage pump 41 for discharging the sewage to the sewer is installed. The control panel 42 in the sewage tank 40 performs water level detection of the sewage tank by the water level sensor 43 and drive control of the drainage pump 41.

  The monitoring computer 51 is assumed to be installed in a central monitoring room (for example, a station service room at a station) 50 in this system. The monitoring computer 51 takes in the operation / alarm signals of the control panels 32 and 42, finds any abnormality in each facility, and accumulates data that leads to early detection of facility abnormality. If a facility abnormality occurs, an alarm is issued in the monitoring computer 51, and based on this, a repair or confirmation can be requested from a company or office that undertakes maintenance management of toilet facilities. The monitoring computer 51 may be an information terminal device such as a personal computer, or may be an alarm panel dedicated to this system.

  The management computer 61 is installed in the management office 60 in this system. The management office 60 is a management office that remotely manages this system. For example, the management computer 61 accumulates the detection data of the human sensor 11 and the door opening / closing detection sensor 12 (or the control panel 13 of the multipurpose toilet) provided in the toilet 10 via the Internet 100 and forms a database. . In addition, the management computer 61 statistically analyzes the accumulated data to calculate the use frequency and use state of the toilet 10. Such statistical data analysis can be used for prediction of toilet equipment cleaning / inspection time and preventive maintenance of toilet equipment, etc., and can be used to prevent equipment malfunctions and reduce the burden on repair workers. .

  In addition, information terminal devices of companies and offices (for example, offices A and B) that undertake maintenance management of the toilet 10 and toilet facilities may be connected to the system via the Internet 100. For example, a cleaning company that undertakes cleaning of the toilet 10 can determine the number of toilet users from the detection data of the human sensor 11 and the door opening / closing detection sensor 12 and predict the replenishment time of consumables such as toilet paper. . Alternatively, the management company of the sewage tank 40 can predict equipment abnormality early from the drainage pump 41, the operation signal, the detection signal of the water level sensor 43, etc., and can perform preventive maintenance by inspection or the like.

  Moreover, a general user may connect to this system with the smart phone tablet 80 etc., and you may make it receive a part of information obtained from this system as a cloud service. For example, the current use status of the toilet can be given as data to the general user from the detection data of the door opening / closing detection sensor 12 (or the control panel 13 of the multipurpose toilet). Thereby, in a large facility or the like where a plurality of toilets 10 are provided, a toilet user can be guided to an empty toilet 10.

  Furthermore, in this system, the use status (use state or non-use state) of a specific toilet room is detected from the detection data of the door open / close detection sensor 12 (or the control panel 13 of the multipurpose toilet), and used for a long time or not used for a long time. The toilet used can be detected.

  For example, if a specific toilet room is unnaturally used for a long time, the user may be in poor health in the toilet room, or the toilet room may be used for other purposes. Conceivable. Or the door of a toilet private room may be out of order and in a state that cannot be opened. Therefore, it is necessary to confirm the situation when long-term use of a specific toilet room is detected. In this system, the flow of processing when a long-term use of a toilet room is detected is shown in FIG. In the following description, a case where the facility to which the present system is applied is a station is illustrated.

  First, when the door open / close detection sensor 12 provided in the toilet private room continuously detects the closed state, the duration is compared with a predetermined first threshold (for example, 30 minutes), and the duration of the closed state is compared. When the first threshold value is exceeded, it is detected as a long-time trouble, and a station staff is notified by e-mail via the monitoring computer 51. The station staff who received the trouble by e-mail confirms the contents (in which toilet had trouble using for a long time) on the e-mail screen and went to the site to confirm.

  As a result of the confirmation, if the user is in other uses or is in poor physical condition and can be dealt with only by the station staff, the completion report is input to the system via the monitoring computer 51 after dealing with this. If equipment damage (door failure, etc.) has occurred, contact the facility maintenance section of the electric railway company and take necessary measures such as arranging repairs.

  On the other hand, if a specific toilet room is unnaturally unusable for a long time, toilet bowl contamination may occur, or equipment failure in the toilet room may occur. Therefore, it is necessary to check the situation even when it is detected that a specific toilet room is not used for a long time. FIG. 3 shows a processing flow when it is detected that the toilet private room is not used for a long time in this system.

  First, when the door open / close detection sensor 12 provided in the toilet private room continuously detects the open state, the duration is compared with a predetermined second threshold (non-use state detection threshold: for example, 90 minutes). When the duration of the open state exceeds the second threshold, it is detected as a trouble that has not been used for a long time, and is reported to the station staff via the monitoring computer 51 by e-mail. The station staff who receives the trouble by e-mail confirms the contents (which toilet has been unused for a long time) on the e-mail screen and goes to the site to confirm.

  As a result of the confirmation, if there is no particular problem, a simple response with only a confirmation is made, and a completion report is input to the system via the monitoring computer 51.

  In addition, if the toilet bowl is contaminated, the cleaning contractor is contacted, and the cleaning contractor responds and takes measures (cleaning, etc.). After the completion report from the cleaning contractor, the completion report is sent via the monitoring computer 51. Into the system.

  Also, if there is equipment failure in the toilet private room, the facility maintenance section of the railway company is contacted, and the facility maintenance section contacts the equipment supplier. The equipment contractor will arrange a repair shop after confirming the site, and the repair company will handle and deal with it (such as equipment repair). Then, the equipment contractor confirms the result after the response by the repair shop and inputs a completion report to the system. The facility maintenance section can confirm the completion report by this system.

  As described above, the present system compares the duration of use of the toilet room with the first threshold value, and if the usage state exceeds the first threshold value, it is detected as a long-time use trouble. As a result, it is possible to take necessary measures for troubles of long-term use. Moreover, this system compares the duration of the non-use state of a toilet private room with a 2nd threshold value, and when a non-use state exceeds a 2nd threshold value, it detects as a trouble of non-use for a long time. This makes it possible to take necessary measures even for troubles that have not been used for a long time. Note that the comparison is performed by, for example, the monitoring computer (control unit) 51. In this case, the first threshold value and the second threshold value are stored in advance in the storage unit of the monitoring computer 51, and the monitoring computer 51 uses the stored first threshold value and second threshold value to continue the use state or the non-use state. Compare with time.

  However, when this system is applied to a facility (for example, a station) where the number of toilet users fluctuates greatly throughout the day, if the second threshold is a fixed value, long-term non-use of the toilet private room is detected appropriately. Difficult to do. For example, a toilet in a station usually has a crowded time zone and a non-crowded time zone, and if the threshold value is increased, rapid detection cannot be performed in the crowded time zone, while on the other hand, if the threshold value is shortened, the crowded time zone. Unnecessary detection increases.

  For this reason, in this system, the 2nd threshold value for detecting the abnormality which is not used for a long time is changed with a time slot | zone. Specifically, the second threshold value is set to a short time during a busy time zone so that rapid detection can be performed. On the other hand, in a non-congested time zone, the second threshold is set to a long time to suppress an increase in unnecessary detection. Note that the number of times that the setting value of the second threshold is changed in one day is not particularly limited.

  An appropriate value of the second threshold can be obtained by statistically analyzing the accumulated data of the human sensor 11 and the door opening / closing detection sensor 12 (or the control panel 13 of the multipurpose toilet). Further, the setting and registration of the second threshold value in this system may be performed by manual input. Alternatively, this system (for example, the management computer 61) has a machine learning program, and the second threshold is set based on the detection data of the human sensor 11 and the door opening / closing detection sensor 12 (or the control panel 13 of the multipurpose toilet). It may be automatically updated. In this case, the machine learning method implemented in the present system is not particularly limited in the present invention, but for example, a deep learning method can be used.

  By adopting a configuration in which the second threshold is automatically updated by machine learning in this way, for example, when this system is applied to a toilet in a station, a change occurs in a time zone in which the surrounding environment of the station changes and becomes crowded. However, the second threshold value can be quickly changed to an appropriate value corresponding to the change.

  When the second threshold value is automatically updated by machine learning, the input data used for analysis is limited to only the detection data of the human sensor 11 and the door opening / closing detection sensor 12 (or the control panel 13 of the multipurpose toilet). is not. For example, other data that affects the number of users at the station, such as weather data, can be used as input data for machine learning, and fluctuations in the number of toilet users can be predicted using various data.

  In the above description, the second threshold value for detecting abnormalities that are not used for a long time is changed according to the time zone, but the first threshold values for detecting abnormalities that are used for a long time are not changed according to the time zone. It is good also as a fixed value. This is because the time for which one user continuously uses the toilet private room is not greatly affected by whether or not it is a crowded time zone, and therefore the first threshold value is less likely to be changed depending on the time zone. However, the present invention is not limited to this, and the first threshold value may be changed according to the time zone. For example, in a non-congested time zone, even if the user is in poor health in the toilet private room, it is difficult for other users to notice, so it is possible to shorten the first threshold setting value in a non-crowded time zone. It is done.

  This system is preferably applied to a toilet in a facility where the number of toilet users greatly varies during the day, and is particularly suitable for a toilet in a station. However, the present invention is not limited to this, and may be applied to an SA or PA toilet on a highway, or a toilet of a commercial facility or an amusement facility.

  The embodiments disclosed herein are illustrative in all respects and do not serve as a basis for limited interpretation. Therefore, the technical scope of the present invention is not interpreted only by the above-described embodiments, but is defined based on the description of the scope of claims. Moreover, all the changes within the meaning and range equivalent to a claim are included.
