The notification unit 63 notifies the destinations of higher priority in accordance with the priority of the notification, and if there is no response from the destination of higher priority or does not receive the call even though the call is made, the destination of notification of lower priority is notified. Alternatively, notification may be attempted multiple times to the highest priority notification destination, or both may be performed in parallel. The notification unit 63 may simultaneously notify a plurality of notification destinations in parallel.

Specific examples of the content of the abnormality to be detected and the notification destination will be described below.

The abnormality detection unit 62 may determine that an abnormality has occurred when the usage status information indicating the usage state of the toilet device 30 matches the condition held in the abnormality detection condition holding unit 75 . For example, the abnormality detection unit 62 may determine that an abnormality has occurred when it acquires information indicating that the amount of water inside the toilet bowl of the toilet device 30 has exceeded a predetermined value. If sewage overflows from the toilet bowl due to clogging of the drain pipe, etc., it may have a great effect not only on the inside of the toilet room 21 but also on the surroundings, so the overflow of sewage is quickly detected and necessary measures are taken. It is very important for the operation of facilities, etc., to have a system in place to notify the appropriate entity so that they can take action.

The amount of water inside the toilet bowl of the toilet device 30 may be detected by a water level sensor installed on the inner surface or the outer surface of the toilet bowl of the toilet device 30 . When the water level sensor is installed on the outer surface of the toilet bowl, a non-contact type water level sensor such as a capacitance type may be installed. Also, a non-contact type water level sensor such as a capacitance type sensor may be installed on the outer surface of the trap provided between the drain port at the bottom of the toilet bowl and the drain pipe. After the toilet bowl device 30 is used, the toilet bowl is washed with flush water and the dirty water is drained, and water remains in the toilet bowl in a portion lower than the upper end of the trap. If the water level sensor installed on the outer surface of the toilet detects that water remains at the upper end of the trap, it means that the dirty water in the toilet bowl is not being drained from the drain pipe due to clogging of the drain pipe, etc. is estimated, it may be determined that an abnormality has occurred.

If sewage is actually overflowing from the toilet bowl, it will be necessary to clean the toilet room 21 and temporarily restrict the access of users to the toilet room 21 and its surroundings. 63 notifies the subject responsible for cleaning the toilet room 21 in which the toilet device 30 in which the abnormality has occurred and the subject managing the toilet room 21 of the occurrence of the abnormality. In addition, if it is presumed from other information that the cause of the abnormality is due to a malfunction of the equipment such as the toilet device 30, the manufacturer of the toilet device 30 in which the abnormality has occurred is also notified of the abnormality.

The instruction determination unit 64 allows a predetermined number or more of the toilet devices 30 connected to the same water supply pipe or drain pipe to simultaneously perform the predetermined operation or function associated with water supply or drainage when a plurality of toilet devices are to perform the operation or function. Alternatively, the timing for instructing the toilet device 30 to execute a predetermined operation or function is determined so as not to execute the function. For example, the function of flushing a toilet bowl involves draining a relatively large amount of flush water. may be instructed to

The instruction determination unit 64 determines the frequency, time, or amount of drainage of the toilet device 30 connected to the upstream side of the drain pipe among the plurality of toilet devices 30 connected to the same drain pipe, and determines the frequency, time, or amount of drainage that is connected to the downstream side of the drain pipe. The timing for instructing the toilet device 30 to perform a predetermined operation or function involving drainage is determined so as to increase the number of toilet devices 30 that have been used. In order to prevent urinary calculus from adhering to the toilet device 30 and clogging of the drain pipe, when the function of periodically cleaning the toilet device 30 is executed, the drain pipe on the downstream side is supplied with water from the toilet device 30 on the upstream side. Therefore, even if the cleaning frequency of the toilet device 30 on the downstream side is low, a sufficient amount of waste water flows through the drainage pipe on the downstream side, but only the drainage from the toilet device 30 on the upstream side flows into the drainage pipe on the upstream side. Not flowing. Therefore, by increasing the cleaning frequency, time, or amount of drainage of the toilet device 30 connected to the upstream drainage pipe, compared to the toilet device 30 connected to the downstream drainage pipe, wasteful cleaning water can be eliminated. Both upstream and downstream drainage pipes can be properly washed while reducing consumption.

According to such a technique, when the management device 50 collectively remotely controls a plurality of toilet devices 30, problems that may occur due to the plurality of toilet devices 30 performing the same function all at once can be reduced, and smooth operation can be performed. In addition, it is possible to appropriately coordinate and remotely control a plurality of toilet devices 30 .

When executing a predetermined operation or function, the control unit 37 of the toilet device 30 inquires of the management device 50 whether or not there is another toilet device 30 executing that operation or function nearby. The answering unit 66 of the management device 50 acquires information about the operation or function being executed from the plurality of toilet devices 30, stores it in the usage status information holding unit 73, and determines that the predetermined operation or function is being executed from the toilet device 30. Confirm whether or not there is another toilet device 30 executing a predetermined operation or function in the vicinity of the toilet device 30 when it is inquired whether another toilet device 30 exists in the vicinity of the toilet device 30 to answer. The control unit 37 of the toilet device 30 determines whether or not to execute the operation or function or the timing according to the reply from the management device 50 . For example, when executing a predetermined operation or function involving drainage, the control unit 37 inquires of the management device 50 whether or not there is another toilet device 30 executing that operation or function in the vicinity. If there is a reply from 50 to the effect that it exists, it suspends or postpones execution of that action or function.

According to such technology, even when the individual toilet devices 30 operate independently, it is possible to reduce problems that may occur due to interference with surrounding toilet devices 30 and to operate appropriately in cooperation with each other. can.

First, a technique for solving problems related to the use of the toilet device 30 from the viewpoint of the user of the toilet device 30 will be described.

(1) Stopping the Washing and Draining Function The instruction determining section 64 instructs the toilet device 30 to stop the washing and draining function of the toilet device 30 when the abnormality detection section 62 detects an abnormality in the toilet device 30 . When the instruction receiving unit 35 receives an instruction to stop the washing and draining function from the management device 50, the control unit 37 of the toilet device 30 stops the washing and draining function, and the toilet bowl cleaning lever or the toilet bowl cleaning button is operated by the user. Do not drain wash water even if

As described above, the situation where sewage overflows from the toilet device 30 is a situation most desired to be avoided by the user of the toilet device 30 as well as the management, cleaning, and maintenance of the toilet device 30 . According to the toilet management system 10 of the present embodiment, when some abnormality is detected, especially when the water level sensor detects that the water level in the toilet bowl is higher than a predetermined value, or when the drain pipe When an abnormality that can cause sewage to overflow, such as clogging, is detected, the flushing and draining function of the toilet device 30 is forcibly stopped, so that the sewage can be prevented from overflowing from the toilet device 30 thereafter. Contamination by sewage can be minimized.

As described above, the abnormality detection unit 62 may detect an abnormality when the value of the water level sensor provided in the toilet device 30 exceeds a predetermined value. As a result, when the sewage is actually overflowing or is about to overflow, the toilet bowl device 30 drains the wash water to prevent the sewage from overflowing from the toilet bowl. Further, the abnormality detection unit 62 may detect an abnormality based on the detection result of a sensor other than the water level sensor, usage status information of the toilet device 30, and the like. For example, a sensor that detects sound or vibration may be installed near the drainage pipe, and an abnormality may be detected based on the sound or vibration detected after the flushing and draining function is performed by the toilet device 30 . In this case, the abnormality detection unit 62 detects an abnormality even if the sound or vibration that should occur when sewage flows through the drainpipe does not occur even though the washing and draining function has been executed. Alternatively, reference data such as the intensity, duration, frequency, and pattern of sounds or vibrations that normally occur when sewage flows down a drainpipe may be stored in advance, and the sounds or vibrations actually detected by the sensor may be used as a reference. Data may be compared, and an abnormality may be detected when the difference from the reference data exceeds a predetermined range. Thus, regardless of whether the water level of the toilet device 30 is abnormal or not, the abnormality of the drain pipe or the like is accurately detected, and the flush water is drained by the toilet device 30 to prevent sewage from overflowing from the toilet bowl. be able to.

Based on the value of the water level sensor, the instruction determination unit 64 calculates the amount of flush water that can be added to the toilet bowl without causing sewage to overflow from the toilet bowl, and limits the amount of flush water to the calculated amount. The toilet device 30 may be instructed to perform the washing and draining function. As a result, it is possible to test whether or not clogging of the drain pipe can be eliminated by additionally introducing flush water into the toilet bowl while preventing sewage from overflowing.

As a result, when the user notices an abnormality in the toilet device 30, the user can be notified that there is no need to contact the management body, etc., so that the user can feel at ease and the user's convenience is improved. In addition, it is possible to prevent the management entity from being repeatedly contacted repeatedly.

(4) Automatic Closure of Lid When the abnormality detection section 62 detects an abnormality in the toilet device 30 , the instruction determining section 64 instructs the toilet device 30 to close the lid of the toilet device 30 . The controller 37 of the toilet device 30 automatically closes the lid of the toilet device 30 . Thereafter, when it is detected that the user has manually opened the lid, the control unit 37 automatically closes the lid again after a predetermined time has elapsed since the lid was opened. The control unit 37 may lock the lid so that it cannot be opened. As a result, when there is a possibility that the toilet device 30 has an abnormality and dirt remains in the toilet bowl, the cover can be automatically closed to minimize the spread of bad odors.

(5) Automatic Locking of Doors The instruction determination unit 64 controls the doors so as to lock the entrance door of the toilet room 21 or the door 25 of the private room 24 when the abnormality detection unit 62 detects an abnormality in the toilet device 30 .
