The member 3 can be gripped to hold the sitting posture. Moreover, users who do not require the assisting member 3 such as healthy persons use the toilet bowl 2 while the assisting member 3 is in the standby position.

  Here, the first operation of the control unit 110 in the toilet monitoring system of the present embodiment will be described based on the flowcharts shown in FIG. 10 to FIG. That is, in the first operation, the respective indicator lights 50 and 60 and the alarm buzzer 70 are controlled in accordance with the length of the toilet use time of the user A seated on the toilet bowl 2. The flowcharts of FIG. 10 to FIG. 12 are assumed to be continuous with the numbers shown in the respective drawings.

  First, when the user A seated on the toilet 2 is detected by the first sensor 10 (S1), the first indicator 51, 61 (white) of the external indicator light 50 and the internal indicator light 60 is turned on (S2). As a result, the fact that the toilet is in use is indicated by the external indicator light 50 to the outside, and is also indicated by the internal indicator light 60 to the user in the toilet room 1. Next, when the user A, such as a person in need of assistance, rotates the auxiliary member 3 forward and the use of the auxiliary member 3 is detected by the first sensor 10 (S3), the external indicator light 50 and the inside The display time of each display unit in the indicator light 60 is set (S4). Here, when any of the first to third modes is selected by the display time selection switch 90 before the use of the auxiliary member 3 is detected, the display time is set to the selected mode, and the display is performed. If mode selection has not been performed by the time selection switch 90, the second mode is set as a standard time. Each mode is selected, for example, the first mode for users with relatively short toilet use times, or the third mode for users with relatively long toilet use times. The display time selection switch 90 is used to select. Next, timing of the elapsed time of use is started (S5), and the second display 52, 62 (blue) is lighted (S6). Thereby, it can be determined from the display of each of the indicator lights 50, 60 that the user A is using the auxiliary member 3, that is, the user A is a person requiring assistance. When the use of the auxiliary member 3 is detected in step S3, the voice output device 80 is turned on (S7). As a result, when the user A becomes ill while using the toilet, the user A can transmit an abnormality to the outside by voice from the microphone 81 of the voice output device 80. Next, when the detection of the user A seated on the toilet bowl 2 continues (S8) and the first display time has elapsed (S9), the third display portion 53, 63 (yellow) lights up To do (S10). Thereby, it can be judged from the display of each indicator light 50, 60 that the toilet use time is somewhat long. Next, when the detection of the user A seated on the toilet bowl 2 continues (S11) and the second display time has elapsed (S12), the fourth display portion 54, 64 (red) lights up. To do (S13). Thereby, it can be judged from the display of each indicator light 50, 60 that the toilet use time is quite long. Furthermore, the detection of the user A who is seated in the toilet bowl 2 continues (S14), and when the third display time has elapsed (S15), the fourth display portion 54, 64 (red) blinks At the same time (S16), the alarm buzzer 70 is operated to issue an alarm (S17). As a result, it is possible to judge from the display of each of the indicator lights 50, 60 that the toilet use time is abnormally long, and the alarm buzzer 70 warns the outside, so the display of the external indicator light 50 and the alarm buzzer 70. An assistant who notices the warning can enter the toilet room 1 and rescue the user A who can not move while sitting on the toilet bowl 2. At that time, the detection of the user A who is seated on the toilet 2 continues (S18), and when the assistant or the like operates the release switch 100 (S19), the alarm buzzer 70 is stopped (S20) and each display The lights 50 and 60 are turned off (S21), the clocking by the timer is reset (S22), and the process returns to step S1. Further, when the use of the auxiliary member 3 is not detected in step S3 and the user A is not detected (S23), or the user A detects the first display time in steps S8 and S9. If the user A is not detected before the second display time has elapsed in steps S11 and S12, or before the third display time has elapsed in steps S14 and S15. Is not detected, the respective indicator lights 50, 60 are extinguished (S21), and the process returns to step S1. When the user A is not detected before the release switch 100 is operated in steps S18 and S19, the alarm buzzer 70 is stopped (S209), and the display lights 50 and 60 are turned off (S21). And resets the clocking by the timer (S22), and returns to step S1.

  Next, the second operation of the control unit 110 in the toilet monitoring system of the present embodiment will be described based on the flowchart shown in FIG. That is, in the second operation, it is determined whether or not the user A who is not seated in the toilet 2 has fallen in the toilet 1, and controls the respective indicator lights 50, 60 and the alarm buzzer 70. There is.

  First, as shown in FIG. 13, while the body of the user A in the toilet room 1 is detected at the lower position (the height position of the third sensor 30) by the third sensor 30 (S30), the user When the body of A is detected by the fourth sensor 40 also in the upper position (the height position of the fourth sensor 40) (S31), the process returns to step S30. This state is when the user A stands up. Next, as shown in FIG. 14, the body of the user A is detected at the lower position by the third sensor 30 in step S30, but the body of the user A is upward by the fourth sensor 40 in step S31. If the position is not detected, the counting of the elapsed time is started (S32). Thereafter, the body of the user A is detected at the lower position by the third sensor 30 (S33), and the body of the user A is not detected at the upper position by the fourth sensor 40 (S34), When this state continues for a predetermined time (for example, one minute) (S35), the fourth display portion 54, 64 (red) of each of the indicator lights 50, 60 blinks (S36), and the alarm buzzer 70 is activated. And issue an alarm (S37). This state is a case where the user A may fall down. As a result, a helper or the like who notices the display of the external indicator light 50 and the alarm of the alarm buzzer 70 can enter the toilet room 1 and rescue the user A who is falling inside the toilet room 1. At that time, when the assistant or the like operates the release switch 100 (S38), the alarm buzzer 70 is stopped (S39), and the respective indicator lights 50, 60 are extinguished (S40), and the clocking by the timer is reset (S41). ), Return to step S30. In addition, when the body of the user A is detected at the upper position by the fourth sensor 40 before the predetermined time elapses in steps S33, S34 and S35, the time counting by the timer is reset (S41). Return to S30. This state is, for example, the case where only the foot of the user A is temporarily detected by the third sensor 30.

  As described above, according to the present embodiment, a plurality of different displays are displayed in stages on each of the indicator lights 50 and 60 according to the length of the toilet use elapsed time. It is possible to confirm the length of the toilet use elapsed time by the display step of, and when the use of the toilet is abnormally long, the user A can be rescued by judging that something has changed. In this case, when the seating of the user A on the toilet bowl 2 is detected by the first sensor 10 and the use of the auxiliary member 3 is detected by the second sensor 20, clocking of the toilet use elapsed time is started Therefore, the stepwise display of each indicator light 50, 60 according to the toilet use elapsed time can be performed only when the auxiliary member 3 is used. As a result, even when the use time of a healthy person who does not use the auxiliary member 3 is long, there is no case where the person in need is mistakenly identified as having an abnormal condition and rushed into the toilet. You can always monitor the

  In addition, since the external indicator light 50 for displaying the toilet use condition outside the toilet room 1 and the internal indicator 60 for displaying the toilet use condition inside the toilet room 1 are provided, the toilet use condition is displayed on the toilet Not only an assistant outside the room 1 but also the user A in the toilet room 1 can be displayed. As a result, the user can confirm that the display of the toilet use state is being performed while using the toilet, and the user A can feel a sense of security.

  Furthermore, since each indicator light 50, 60 is displayed in different colors depending on the display of each stage according to the toilet use elapsed time, it is easy to visually check the passage of toilet use time by changing the color of the display. It is possible to quickly detect a change in user A while using the toilet.

  In addition, since the display time of each step can be arbitrarily changed by the display time selection switch 90 according to the toilet use elapsed time in each of the indicator lights 50, 60, a plurality of users with different lengths of normal toilet use time Even when using, the display time of each stage can be changed for each user, and the monitoring of the toilet usage status suitable for each user can be performed.

  Furthermore, since the user A in the toilet room 1 is provided with the voice output device 80 capable of outputting voice to the outside, when the user A becomes ill while using the toilet, the user A makes a call If it is not in an impossible state, an abnormality can be transmitted to the outside by voice from the microphone 81 of the voice output device 80, and the user A promptly rescues the outside regardless of the display stage of each indicator light 50, 60. It can be asked.

  In this case, when the seating of the user A on the toilet bowl 2 is detected by the first sensor 10 and the use of the auxiliary member 3 is detected by the second sensor 20, an audio output is possible. Therefore, the voice output device 80 can output voice only when the user A who needs the use of the auxiliary member 3 uses the toilet, and the auxiliary member 3 is not used. When a healthy person uses the toilet, it is possible to prevent unnecessary voice output to the outside.

  Further, the third sensor 30 for detecting the body of the user A at a predetermined height position in the toilet room 1 and the body of the user A at another predetermined height position lower than the third sensor 30 are detected. And the fourth sensor 40 detects the body of the user A and the third sensor 30 does not detect the body of the user A. Since a predetermined alarm (red flashing on the display unit 54 and alarm sound of the alarm buzzer) is issued as having a possibility of falling inside, a helper or the like who noticed the alarm enters the toilet room 1, The user A who falls in the toilet room 1 can be rescued. As a result, even when the user A does not use the toilet bowl 2, it is possible to detect a change in the user A, so it is possible to further strengthen the monitoring of the user A who uses the toilet.

  Although the auxiliary member 3 is rotatably attached to the wall surface of the toilet room 1 in the present embodiment, the floor of the toilet room 1 as in the second embodiment shown in FIGS. 16 and 17 is shown. The use of the auxiliary member 4 moving along the surface is advantageous when processing for attaching the auxiliary member to the wall surface of the toilet room 1 can not be performed. The auxiliary member 4 is supported by a guide rail 4a installed on the floor surface of the toilet room 1, and moves in the left-right direction along the guide rail 4a as shown in FIG. In this case, when using the auxiliary member 4, when the auxiliary member 4 is moved to the front of the toilet bowl 2, the auxiliary member 4 is detected by the second sensor.
