Description

  The present invention relates to a toilet system.

  Toilets are provided with a water supply pipe for supplying water to the toilet and wash basin, and a drain pipe for discharging drainage from the toilet and wash basin to the outside.If this water supply pipe or drain pipe is damaged, water leakage may occur. There is.

  For example, in a water supply pipe made of resin, cracks may occur due to a water hammer and water leakage may occur. Also, water leakage may occur due to displacement of the pipe due to the earthquake, deterioration of the sealing material, and the like. Further, clogging of the drain pipe may cause drainage to overflow from the toilet bowl or wash basin.

  In recent years, the number of drains provided on the floor of a toilet has been reduced, and when water leaks, it immediately leaks into a corridor or exudes downstairs, which is a serious problem.

  Therefore, when a water leak accident occurs, the system notifies the water leak handling control server of the accident information via a network, and the water leak handling control server informs the contractor or insurance company of the information corresponding to the accident information. Is known (Patent Document 1).

Connected. The control device 6 may be provided in the toilet 1 or may exist independently of the toilet 1.

  The toilet 1 is a public toilet used in a commercial facility such as a department store, a station, or the like, for example. Although FIG. 2 shows the toilet 1 provided in one building 50, the toilet 1 may be provided in each of a plurality of buildings. Further, the toilet 1 acquires data using a sensor or the like provided in the toilet and transmits the data to the server 2 at predetermined intervals, for example.

  The server 2 collects information from the toilet 1 and transmits information for changing settings of devices provided in the toilet 1. The administrator terminal 3 is a computer for a service provider relating to the toilet 1 to connect to the system. The data collected by the server 2 is read, for example, by the administrator terminal 3, and is tabulated or verified for any abnormality. Further, the settings of the devices provided in the toilet 1 may be changed via the network 5. For example, information for instructing a change in setting is registered from the administrator terminal 3 to the server 2 and information for reflecting the change from the server 2 to the toilet 1 is transmitted at a predetermined timing.

  The notification destination server 4 is a destination computer that notifies, when an abnormality is detected in the toilet 1, that fact. When a predetermined state is detected in the toilet 1, information is transmitted from the toilet 1 to the server 2 each time, and the server 2 transmits, for example, an e-mail to the notification destination server 4.

There may be. For example, the water leakage may be estimated from the usage state of a device such as a toilet bowl, a wash basin, or an ostomate, which is a flow path for water supply or drainage, and a flow rate detected by a flow meter provided in a water supply pipe. For example, when the device to be measured does not use water supply (stop state), that is, when the toilet is not flushing water, water is flowing through the flow meter provided in the water supply pipe. Is detected, it is detected that there is water leakage. Further, the present invention is not limited to the case where the flow meter is provided in the water supply pipe, and a flow meter may be provided in the drain pipe, and it may be detected that there is water leakage when drain water is flowing when the target device is stopped.

<Water leak detection processing>
Next, a water leak detection process performed by the system will be described. FIG. 10 is a process flow illustrating an example of a water leak detection process performed by the control device 6 of the toilet 1. The control device 6 repeatedly executes the water leakage detection process of FIG. 10 periodically or at a predetermined timing.

When the water leak detection process of FIG. 10 is started, the control device 6 first obtains the detection result of the water leak sensor 142e (Step S20), and determines the presence or absence of water leak (Step S30). That is, when water leaks from the water supply pipe 61 or the drain pipe 62 and reaches the water leak sensor 142e, and the water leak sensor 142e detects the presence of water, it is determined that there is water leak. Here, if it is determined that there is no water leakage (Step S30, No), the process of FIG. 10 is terminated, and if it is determined that there is water leakage (Step S30, Yes), the process proceeds to Step S35.

  In step S35, the control device 6 changes the threshold value of the water leak sensor 142e to the second threshold value and acquires the detection result again. Then, when the detection result of the water leak sensor 142e exceeds the second threshold value, it is determined that there is a water leak of a predetermined amount or more (step S40). For example, when water contacts and conducts between the electrodes 411 of the water leakage sensor 142e, and when the electric conductivity or the resistance value between the electrodes 411 exceeds the first threshold value, it is determined that there is water leakage (step S30), and the second If the threshold value is exceeded, it is determined that there is a leak of a predetermined amount or more (step S40). Note that the first threshold and the second threshold are values indicating the degree of conduction between the electrodes 411, and the second threshold is a value having a higher degree of conduction than the first threshold, that is, water leakage. Is a value indicating a state in which the current between the electrodes 411 easily flows. It is determined that the threshold value has been exceeded when the state in which electricity flows more easily than each threshold value. For example, the second threshold has a lower resistance value and a higher electrical conductivity than the first threshold. When the second threshold is exceeded, the control device 6 may calculate the urgency based on the time from when the first threshold is exceeded to when the second threshold is exceeded. For example, if the elapsed time from exceeding the first threshold to exceeding the second threshold is short, the urgency is high, and if the elapsed time is long, the urgency is low. Ask for.

When the detection result of the water leak sensor 142e exceeds the second threshold value and determines that there is water leakage of a predetermined amount or more (Step S40, Yes), the control device 6 controls the water supply valve 63 or the water supply valve 64 to perform water leakage. The water supply at the location where the water supply is stopped is stopped (step S50). That is, when water leakage is detected in the toilet 1 on a specific floor, the water supply valve 64 on that floor is switched to stop water. When water leakage is detected in the toilet 1 on a specific floor, the water supply valve 64 on that floor is switched to stop water. On the other hand, if water leakage occurs at the portion of the vertical water supply pipe 611 or the vertical drainage pipe 621 relating to all the toilets 1, the water supply valve 63 is switched to water stoppage.

  If it is determined in step S40 that there is no water leakage equal to or greater than the predetermined amount (step S40, No), the control device 6 proceeds to step S60 without stopping water.

  Then, the control device 6 specifies the position of the water leak based on the installation position of the water leak sensor 142e that has detected the water leak, the position of the water leak, the amount of the water leak (whether or not the second threshold has been exceeded), and the water stoppage. The presence / absence, the position where the water was stopped when the water was stopped, the degree of urgency, and the like are transmitted to the server 2 as water leakage information (step S60). Note that the server 2 transmits the information on the water leakage to the notification destination server 4.

<Water supply valve operation confirmation processing>
As described above, in the present embodiment, when water leakage of a predetermined amount or more occurs, the water supply valves 63 and 64 are switched to water stoppage. However, if the water supply valves 63 and 64 are not operated for a long time, rust and minerals adhere to the water supply valves 63 and 64. May not be able to open and close. If the water supply valves 63 and 64 are not closed, it is not possible to switch to water stoppage even when water leakage is detected. Therefore, in the present embodiment, the water supply valves 63 and 64 are periodically closed at night or on holidays. Perform processing to confirm operation. That is, the operation of FIG. 11 is performed.

  When the operation in FIG. 11 is started, the control device 6 switches the water supply valves 63 and 64 to be checked to stop water (step S120). The water supply valves 63 and 64 may be checked one by one, or the water supply valves 64 connected in parallel may be simultaneously checked.

Next, the control device 6 controls the flush valve 78 connected to the water supply pipe 61 provided with the water supply valves 63 and 64 to be checked to cause the flush water to flow (step S130), and the flush valve 78 The flow rate of the washing water is detected by the flow meter (step S140), and it is determined whether the washing water flows (step S150). Here, if the flow rate of the cleaning water is equal to or less than the predetermined value, that is, if the cleaning water does not flow, the process of FIG. On the other hand, if the flow rate of the wash water is equal to or higher than the predetermined value, that is, if the wash water is flowing, the water stop is not performed normally (Yes in step S150), and the server 2 is notified of the operation failure. (Step S160).

<Notification process>
In the present system, the toilet 1 transmits various data (also referred to as “sensing data”) collected via the sensor 142 to the server 2 in addition to the information on the water leakage. The data stored in the server 2 by this processing can be downloaded from the administrator terminal 3 or the like, and the administrator operating the administrator terminal 3 can grasp or analyze the state of the toilet 1. it can. When a predetermined state determined to be abnormal, for example, is detected via the sensor 142, the notification is immediately sent to the notification destination server 4 or information is stored in the server 2.

  First, when each of the sensors 142 detects information, the sensor 142 converts the detected information into a digital signal and outputs the digital signal to the control unit 141. On the other hand, the control unit 141 causes the data storage unit 143 to store the information output by the sensor 142.

  When the sensor 142 is a motion sensor, the control unit 141 causes the data storage unit 143 to store the number of toilet users (that is, the number of times the motion sensor has detected a person). When the sensor 142 is a flow rate sensor, the control unit 141 causes the data storage unit 143 to store the total flow rate of the washing water that has flowed into the toilet. When the sensor 142 is a door lock sensor, the control unit 141 stores information indicating whether or not the door is locked in the data storage unit 143. When the door is locked, the control unit 141 waits after the door is locked. Is counted. When the sensor 142 is a seat sensor, the control unit 141 stores information indicating whether or not a person is sitting on the toilet seat in the data storage unit 143. When the person is sitting on the toilet seat, the control unit 141 detects the seat. The elapsed time from is counted. The elapsed time since the door was locked and the elapsed time since the seat was detected can be counted using, for example, a timer included in the control device 6 or the control unit 141.

  Further, the control unit 141 outputs information stored in the data storage unit 143 to the control device 6 of the toilet 1 at predetermined intervals. Then, the control device 6 transmits to the server 2, and the server 2 transmits to the notification destination server 4.

  According to the present embodiment, the administrator who operates the administrator terminal 3 and the person in charge of the notification destination server 4 can grasp the situation of the toilet 1 from a remote place in detail. In particular, it is possible to immediately know the occurrence of water leakage, and to take prompt action.

  According to the present embodiment, as the information on the water leak, the position of the water leak, the amount of the water leak, the control status of the water supply valve (whether or not water stopped), and the degree of urgency can be notified. Appropriate measures can be taken.
