The notification unit 63 may notify a plurality of notification destinations simultaneously and in parallel.

Hereinafter, the content of abnormalities to be detected and specific examples of the notification destination will be described.

The abnormality detecting unit 62 may determine that an abnormality has occurred when the use condition information indicating the use condition of the toilet device 30 matches the condition held by the abnormality detecting condition holding unit 75. For example, when the abnormality detection unit 62 acquires information indicating that the amount of water inside the toilet bowl of the toilet device 30 exceeds a predetermined value, it may determine that an abnormality has occurred. If sewage water overflows from the toilet bowl due to clogging of the drain pipe, etc., it may have a very large influence not only inside the toilet 21 but also around the toilet 21, so that the overflow of sewage can be quickly detected and necessary measures can be taken. It is very important to have a system for notifying appropriate actors in operating facilities.

The amount of water inside the toilet bowl of the toilet device 30 may be detected by a water level sensor provided on the inner or outer surface of the toilet bowl of the toilet device 30. When a water level sensor is installed on the outer surface of the toilet bowl, a non-contact type water level sensor such as a capacitance method may be installed.

In the case of performing a function of periodically cleaning the toilet device 30 in order to prevent adhesion of uneven stones to the toilet device 30, clogging of the drain pipe, etc., the upstream toilet device 30 is included in the downstream drain pipe. ) Also flows, so even if the washing frequency of the downstream toilet device 30 is low, sufficient drainage flows to the downstream drain pipe, but only the drain from the upstream toilet device 30 flows into the upstream drain pipe. Does not. Therefore, the washing frequency, time, or amount of drainage of the toilet device 30 connected to the upstream drain pipe is increased rather than the toilet device 30 connected to the downstream drain pipe, thereby suppressing the consumption of unnecessary washing water and Both the drain pipe on the side and the drain pipe on the downstream side can be properly cleaned.

According to such a technique, when the management device 50 collectively remotely controls a plurality of toilet bowls 30, problems that may occur when the plurality of toilet bowls 30 simultaneously execute the same function are reduced. , It is possible to smoothly and appropriately cooperate with the plurality of toilet devices 30 to remotely control them.

When performing a predetermined operation or function, the control unit 37 of the toilet device 30 inquires with the management device 50 whether or not another toilet device 30 executing the operation or function exists in the vicinity. . The answering unit 66 of the management device 50 acquires information about the operation or function being executed from the plurality of toilet bowls 30 and stores it in the usage status information holding unit 73, and the toilet device 30 When it is inquired whether or not there is another toilet device 30 performing a predetermined operation or function in the vicinity, another toilet device 30 executing a predetermined operation or function around the toilet device 30 It checks whether it exists and responds. The control unit 37 of the toilet device 30 determines whether or not to execute the operation or function or the timing in response to a response from the management device 50. For example, in executing a predetermined operation or function involving drainage, the control unit 37 informs the management device 50 whether or not another toilet device 30 executing the operation or function exists in the vicinity. When an inquiry is made and there is a response from the management device 50 indicating that it exists, the execution of the operation or function is suspended or delayed.

According to such a technique, even when the individual toilet units 30 operate independently, defects that may occur due to interference with the surrounding toilet units 30 can be reduced, and appropriate cooperative operation can be performed.
