(Hereinafter referred to as "wanderers"), protection measures are required. In particular, when a wandering person is in a nursing home or family, it is always necessary to monitor family members, home helpers, etc., and family members living together (hereinafter referred to as residents), but wandering people are monitored. In this case, it is difficult for the caregiver to accompany the wandering person for 24 hours. Therefore, as a method for detecting a wandering person who tries to go out of the house by a resident, for example, JP-A-8-65413 and JP-A-2000-08.
As disclosed in Japanese Patent No. 1488, a transmitter that generates a radio wave or a visible light having a predetermined frequency is used as a charm, and is attached to clothes so that a wandering person does not know that it is a transmitter. There is a method of carrying the radio wave and visible light from the transmitter at the entrance and exit and letting the residents know. In addition, in order to monitor the entry and exit of a wandering person from the entrance and exit of a house and to detect the intrusion of a suspicious person, for example, Japanese Patent Laid-Open No. Hei 7
As disclosed in Japanese Patent Publication No. 079291, there is a method in which a video camera is provided near the entrance and an alarm is issued by a warning generator to notify a resident when a wandering person or a suspicious person is detected.

[0003]

However, according to the conventional method of detecting a wandering person approaching the doorway by carrying the transmitter with the wandering person, the wandering person finds the transmitter or removes it. I sometimes hate my phone and cause problems. Therefore, there is a problem that the resident cannot sufficiently monitor the wandering person's outings because the monitoring is interrupted or impossible. Further, when a wandering person or a suspicious person is detected by installing a video camera near the entrance, it is necessary to always take a picture with the video camera and record the video, which is a problem that a lot of labor and cost are required. The present invention has been made in view of such circumstances, and provides a wandering person detection device that detects a wandering person who tries to open a door from the inside and issues an alarm, without causing a wandering person to carry a transmitting device.

The case 12 is fixed to the door body at a distance of about 15 to 30 cm above a door knob 13 which is an example of a door handle in this embodiment. On the lower side wall 14 of the case 12, a passive sensor 16 that detects that a part of the human body has entered the detection area 15 near the door knob 13 and thumb turn (locking / unlocking lever) 13a is attached. This passive sensor 1
Reference numeral 6 is a so-called pyroelectric sensor, and the switch is turned on by detecting a change in infrared rays emitted from a human body or the like. As the passive sensor 16, one having a relatively narrow detection range is used, and as shown in FIG.
The object is detected only in the vicinity of the door knob 13 and the thumb turn 13a (in a range of about 40 to 60 cm from the passive sensor 16) arranged obliquely below the case 12 (about 20 to 30 degrees from the door surface). There is. It should be noted that when unlocking the door 11 from the outside by using the key of the door 11, the inner thumb turn 13a operates, but in this case, since the thumb turn 13a is metal, the passive sensor 16 does not detect.

A reflective infrared sensor 18, which is an example of a door open / close detector for detecting opening / closing of the door 11, is provided on the side wall 17 of the case 12 facing the door frame adjacent to the door knob 13. When the door 11 is closed, the infrared sensor 18 detects the door frame or a wall in the vicinity thereof and is turned on, but when the door 11 is opened, the state is released and the output is turned off. It is like this. The present invention can be applied to the door 11 which is a hinged structure or a sliding door. On the front side of the case 12, a key input switch 19 which is an example of a personal identification code input means and an electronic buzzer 20 which is an example of an alarm device are provided. The key input switch 19 is composed of two push button switches (key switches), that is, upper and lower push button switches (numbered 1 and 2). So, for example, 1,
A simple personal identification number (personal identification code) such as 2, 1, etc. can be entered. The electronic buzzer 20 is composed of a small speaker and emits an alarm sound when a signal having a frequency corresponding to the sound is input. In addition, you may use the thing of the structure which emits a sound only when a voltage is applied.

On the lower side wall 14 of the case 12, in addition to the passive sensor 16, two changeover switches 21 and 22 are provided.
Is provided. The changeover switch 21 switches the sound of the electronic buzzer 20 between an alarm sound (beep) and an alarm sound (beep, beep, ...). If the wandering person tries to actuate the changeover switches 21 and 22 during monitoring, the passive sensor 16 operates to give an alarm. Further, the changeover switch 22 is a switch (a crime prevention function changeover switch) that is changed when a person tries to open the door 11 from the outside so as to exert a crime prevention function.
Is. In the case 12, a controller 23 including a microcomputer, which is an example of control means, an amplifier 24 connected to the controller 23, and a radio wave sending unit 2 that emits a specific radio wave signal to the outside.
5, a light emitting diode 26 that indicates an operating state, and a battery 27 that serves as a power source for these. Controller 23
A program that controls the whole operation is written in advance.

On the other hand, a receiving device 28 for receiving a weak radio wave of the radio wave sending section 25 and issuing an auxiliary alarm is separately provided, for example, in a living room or the like. The receiving device 28 includes a radio wave receiving section 29.

2 and an electronic buzzer 33, and further has a battery 34 and a changeover switch 35 as a power source section. The changeover switch 35 is used to switch, when a notification sound signal is received from the radio wave sending section 25, whether to emit the notification sound or the warning sound. Therefore, when there is an alarm sound signal from the radio wave sending unit 25, the alarm sound is emitted regardless of the state of the changeover switch 35. Further, a switch 35a for stopping the alarm sound is provided. The switch 35a may be a simple push button switch or a two-key personal identification number input switch. The receiving device 28 may be omitted, or a plurality of receiving devices 28 may be installed in different places.

Next, the program operation written in the controller 23 and its operation will be described with reference to FIGS. This wandering person detection device 10
When you activate the, first, by the infrared sensor 18,
It is confirmed whether or not the door 11 is opened (step S
1). When it is detected that the door 11 is open, it is considered that there is an operation for opening the door from the outside, and when the changeover switch 22 for the crime prevention function is turned off (step S2), a notification is given. A sound (beep) is emitted from the electronic buzzer 20 (step S3), and a radio signal for generating a notification sound is transmitted from the radio wave sending section 25 (step S4). After this, the process returns to the start through the prohibition circuit (step S5). When the prohibiting circuit immediately repeats the operation from step S1 to step S4, the notification sound becomes continuous. Therefore, a timer of about 10 seconds (variable setting in the range of 1 to 15 seconds) is provided to stabilize the system. I am trying to Therefore, if the door 11 remains open, the wandering person detection device 10 emits a notification sound once in about 10 seconds. Further, this prohibition circuit also works to stop the generation of alarm sound for about 10 seconds. As a result, when a person who opens the door from the outside enters the inside and closes the door, the passive sensor 16 operates and the alarm is not activated. When the switch 22 is turned on in step S2, an alarm sound (peepo, beepo) is emitted from the electronic buzzer 20 (step S9), and a wireless signal for generating an alarm sound is emitted (step S10). Then, the set time of the timer (for example, 30 seconds) is counted (step S11), the alarm is stopped (step S12), and the process returns to the start.

Next, when the door 11 is closed in step S1, the passive sensor 16 is in an operating state. If the wandering person tries to touch the door knob 13 and a hand, which is a part of the human body, enters the detection area 15, the output of the passive sensor 16 is turned on (step S).
6). Next, the light emitting diode (red LED) 26 provided on the front surface of the case 12 blinks (step S7),
It is detected whether the changeover switch 21 is in the alarm side or in the alarm side during the alert system (step S
8). When the changeover switch 21 is in the notification side, the process moves to step S3 to generate a notification sound (step S3).
3), emits a wireless signal (step S4). Note that after step S6, the infrared sensor 18 may detect that the door 11 has been opened, and the process may proceed to step S7. On the other hand, when the changeover switch 21 is set to the alarm side, an alarm sound is emitted (step S9), and a signal of the alarm sound is emitted from the radio wave sending section 25 (step S1).
0). If the passive sensor 16 does not detect the human body in step S6, the input from the changeover switch 19 is monitored (step S13), and if there is an input that matches the predetermined two-key input code, the OK signal tone is output. Emit. This OK signal sound is a notification sound from the electronic buzzer 20.
It is performed by the continuous occurrence (pipping) (step S14). After that, the setting count of the timer is completed (step S11), the alarm is stopped in step S12 (the alarm stop is actually performed, so just check) to return to the start.

In step S13, the key input switch 19
If an erroneous input is detected, the process immediately jumps to step S9 to generate an alarm sound, and in step S10, the radio wave sending unit 25 transmits a wireless signal for emitting an alarm sound. In the above operation, when the alarm sound is emitted in step S9 and the wireless signal for alarm sound generation is transmitted in step S10, and the correct password is confirmed again from the key input switch 19 (step S15), the alarm is immediately issued. Is stopped (step S12).

Therefore, if the changeover switch 21 is set to the alarm side, when the wandering person goes out without permission, the key input switch 19 will not be pressed or will be wrong even if pressed.
When approaching the door knob 13, the passive sensor 16 operates and the electronic buzzer 20 emits an alarm sound. Further, when a family member other than the wandering person comes out, if the personal identification number [for example, 112] is input from the key input switch 19 first, the door 11 can be opened without the alarm sound. When the changeover switch 22 is turned on, a crime prevention function is activated, and an alarm sound is emitted when the door 11 is opened from outside without permission.

Next, the receiver 28 installed in the living room or kitchen will be described with reference to FIG. The receiving device 28 is provided for assisting the sound of the electronic buzzer 20 emitted from the wandering person detecting device 10. Therefore, the receiving device 28 is provided to assist the wandering person detecting device 10.
It operates in accordance with the radio signal of the alarm sound and the alarm sound emitted from 5. First, when the radio wave reception unit 29 receives a signal of an alarm sound or an alarm sound, the wave detection unit 30 detects it and the controller 31 distinguishes it from the alarm sound or the alarm sound (step S1).
a) In the case of a warning sound signal, a warning sound [peep, peep,
..] is emitted from the electronic buzzer 33 (step S2)
a). After that, the timer setting time is counted (step S3a) and the alarm sound is stopped (step S5a).
When the switch 35a for stopping the alarm sound is input (step S4a), the alarm sound stops halfway (step S5a). On the other hand, when it is recognized in step S1a that the alarm sound is generated, it is confirmed whether the changeover switch 35 is on the alarm sound side or the alarm sound side (step S6).
a), if it is on the alarm side, step S2a
Then, the electronic buzzer 33 emits an alarm sound. When the changeover switch 35 is set to the notification sound side in step S6a, the electronic buzzer 33 generates a notification sound [pit] (step S7a).

In the above embodiment, when there is no personal identification number from the key input switch 19, the passive sensor 1
When 6 detects, the alarm / notification signal can be immediately issued. However, if the door 11 is not opened after that, the wandering person cannot go out, so it is detected that the door 11 is further opened. The infrared sensor 18 that does the door 11
It is also possible to emit an alarm sound / notification sound and its signal after detecting the opening of the. The light emitting diode 26 may blink when the door 11 is open and when the battery 27 is almost exhausted. In this embodiment, the reflection type infrared sensor 18 is used as the door opening / closing detector, but a magnetic switch,
There are micro limit switches, infrared emitters / receivers, ultrasonic sensors, etc. Furthermore, as a code input means,
Although the key input switch having two keys is used, it may have a plurality of keys. In this embodiment, the door knob 13 is arranged directly below the passive sensor 16, but depending on the case, the wandering person detection device 10 is used.
(Specifically, the case 12) can be attached to the inner surface of the door on the side of the door knob 13.
