3), and a timer means (5) for measuring the time during which the detection signal is not output.
Warning means (7) for issuing a warning based on the output signal of (
8).

(Operation) According to the configuration described in item 2, when the detection signal from the second detection means (2) is output, the first detection means (3)
) is not output, it indicates that the user of the equipment room is in an immobile state, and the timer means (5)
measures the time of this immobility. Therefore, this measurement 1
If the time between ++T becomes longer than the predetermined time, it is considered that an abnormal situation has occurred to the user of the equipment room, and in this case, the warning means (7) is activated.

The warning issued by (8) allows outsiders to quickly learn of the abnormal situation.

(Embodiments) Preferred embodiments of the present invention will be described below based on the accompanying drawings. Note that this embodiment shows an example in which the present invention is applied to a sanitary equipment room in a nursing home, etc., and in each figure, the reference symbol is attached to each object.

FIG. 1 is a block diagram showing the overall configuration of a sanitary equipment room monitor device according to the present invention, and this monitor device (1) includes:
An infrared sensor (2) installed at a suitable location in the sanitary equipment room to detect the movement of a person entering the room, a switch sensor (3) that detects the presence of a person in the sanitary equipment room, and these infrared sensors (2) and a waveform shaping circuit (4a), (4b) in which the output signal of the switch sensor (3) is equipped with a limiter, etc.
I! is entered via the I! and the person entering the sanitary equipment room is not moving! I! A timer (5) that measures the continuous time, and a buzzer (7) and a warning light that are driven by a drive circuit (6) to issue a warning when the lil+1 predetermined time of this timer (5) reaches a predetermined time. (8) etc.

As shown in FIG. 2, the infrared sensor (2) includes a light emitting device (11) that emits infrared light (10a) from a diode (10) for infrared light emission, and a phototransistor (12) for receiving infrared light. and a light receiver (13) that receives the reflected light (10b) of the infrared rays (LOA) emitted by the light projector (11). 13) is a reflected light variable type infrared sensor that outputs a detection signal only when the amount of received light changes. Therefore, such a sensor (2) is exposed to its irradiation light (10a).
) is installed in a sanitary equipment room so that occupants are illuminated almost all the time, the reflected light will change only when the occupant moves, and the infrared sensor (
2) constitutes an uninvented first detection means for detecting the movement of the person entering the room.

The switch sensor (3) opens and closes in conjunction with the opening and closing of the lighting switch (20) in the sanitary equipment room, as shown in FIG. 3, for example, and detects that the lighting light (21) is in use. This constitutes a second detection means in the present invention that detects that a person is entering the sanitary equipment room.

The timer (5) is a counter-type timer that measures time by counting pulses, for example, by incorporating a pulse generator inside, and continues counting while a predetermined voltage signal is input. The infrared sensor (2) has an enable terminal (5a) that performs a reset, and a reset terminal (5b) that performs a reset every time a predetermined voltage change is input. In addition, output signals from the switch sensor (3) are input to the enable terminal (5a), respectively. Therefore, this timer (5) sets Al1 as the number of pulses the continuous time during which the movement of the person entering the sanitary equipment room is stopped, and constitutes the timer means in the present invention.

The buzzer (7), warning light (8), etc. are installed in a management room or the like in, for example, a master's home, and constitute warning means in the present invention.

Figure 4 is a diagram showing an example of the relationship between each input signal and output signal in the timer using time chart 1. Indicates when a situation occurs.

That is, in the case of A, the detection signal of the infrared sensor (2) is randomly output as shown in b in contrast to the detection signal of the switch sensor (3) (shown in a), and the reset of the timer (5) is outputted as a reset signal. If the measurement is performed at the rising edge of , the timer (5) will measure the time T1 to T5 shown by C, and if the measurement time T+ to T5 are all smaller than the predetermined time To, the timer (5) will measure the time T1 to T5 shown by C. Timer (5
) never outputs a signal.

On the other hand, in the case of B, the output signal of the infrared sensor (2) disappears as shown in b from the time when the abnormal 1s state occurs in the person entering the room, and the timer (5) is not reset after that. When the time To has elapsed, a signal as indicated by d is output and a warning is issued via the drive circuit (6).

FIG. 5 shows an example of a sanitary equipment room, taking a bathroom as an example. The bathroom (30) has a bathtub (31a) on the floor (3
It is a unit type unit formed integrally with 2a), and consists of a bathtub side (31) with a bathtub (31a) and a washing area (32) with a washing space. Washing area side (32)
- On the side wall (34) there is a faucet (35) with a shower (35).
36) is provided, and a mirror (37) is provided above it. The above-mentioned infrared sensors (2) and (2) are installed at two locations: one between the mirror (37) and the faucet (36), and the other on the side wall (3) of the bathtub (31). It will be done. The reason why infrared sensors (2) and (2) are provided at two locations is to enable human movement to be detected in almost the entire area in the bathroom. In addition, a door (not shown) is provided on the front side of the page, and a lighting lamp (39
) is provided with a lighting switch (4o) for turning on the light. This lighting switch (4o) is provided with the aforementioned switch sensor (not shown). Note that the light switch may be provided outside the door, that is, outside the bathroom.

Of course, 4) may be provided outside the toilet.

The aforementioned infrared sensor (2) is installed slightly above the tank (51) so as to illuminate the back of the user (55).

Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments. For example, instead of an infrared sensor, the first detection means may use various sensors that utilize ultrasound (waves, electromagnetic waves, etc.). Also, although the second detection means uses a light switch, it is also possible to use a door key (52a) as shown in FIG. In cases where it is not always used, the sanitary equipment room entrance (60
) near the infrared rays (6) across the passage (81).
2) and a floodlight (63) that irradiates the infrared light (63).
2) and a light receiver (64) that receives light across a passage are installed at two locations separated by a predetermined distance in the direction of one passage, and a person passes through this passage. By doing so, by detecting that the light beams (132) and CG2) are sequentially blocked, it may be possible to detect whether or not a person has entered the sanitary equipment room, that is, whether or not a person has entered the sanitary equipment room. By providing the optical sensors (65) at two locations along the passage in this way, even if a person turns back near the entrance, it can be detected, making it extremely versatile.
