DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described with reference to an embodiment.
[0014]
FIG. 1 is a diagram illustrating a state in which the intrusion warning device according to the present embodiment is attached to the entrance door D. This intrusion warning device is attached to the outdoor side X of the entrance door D, is attached to the detection unit 1 for detecting the person H approaching the entrance door D from the outdoor side X, and the indoor side Y of the entrance door D, and generates an alarm. And a connecting portion 3 formed of, for example, a metal member for connecting the detection unit 1 and the notification unit 2 to each other.
[0015]
As shown in the block diagram of FIG. 2, the detection unit 1 accommodates a first sensor unit 1 a made of, for example, a pyroelectric element, which detects the presence or absence of a person by detecting heat rays radiated from the human body. ing. The notification unit 2 switches the sound emitted from the speaker SP to, for example, “off”, “small”, or “large”, and the sound emitted from the speaker SP, for example, “ping-pong” or “dog”. A switch SW2 for switching to any one of the scream "/" alarm sound "on the substantially surface of the notification unit 2, an alarm generating unit 20 for generating an alarm sound inside, and detecting the presence or absence of a person, For example, it comprises a pyroelectric element and houses a second sensor portion 2a that detects a person approaching the entrance door D from the indoor side Y. The alarm generation unit 20 further includes a microcomputer 20a, an acoustic circuit 20b, and a speaker SP.
[0016]
The connecting portion 3 is formed in an L shape by a central piece 3a and a side piece 3c bent substantially perpendicularly from the central piece 3a, and the central piece 3a is placed on the upper end of the entrance door D, The piece 3c is attached to the entrance door D so as to contact the indoor side Y of the entrance door D. And the detection unit 1 is attached to the front end portion of the central piece 3a through a long hole 3d parallel to the long side direction with the bolt 4, and the transmission unit 2 is attached to the front end portion of the side piece 3c, thereby detecting the detection unit 1 Is arranged on the outdoor side X, and the transmission unit 2 is arranged on the indoor side Y.
[0017]
Next, operation | movement of this intrusion warning device is demonstrated using FIGS. FIG. 3 is a diagram showing the detection area 1a ′ of the first sensor unit 1a and the detection area 2a ′ of the second sensor unit 2a, and FIG. 4 shows the room R near the entrance where the intrusion warning device is attached. FIG. 5 is a flowchart showing the operation of the intrusion warning device.
[0018]
When the second sensor unit 2a detects a human body (step S1) in the standby state in which the speaker volume is switched to high or low by the changeover switch SW1 (step S0), the microcomputer 20a sets the alarm suppression period T. (Step S2). The alarm suppression period T may be a time that is considered necessary for the housekeeper to go out through the entrance, and is set to 10 seconds, for example. The microcomputer 20a measures the elapsed time after setting the alarm suppression period T, and suppresses the generation of an alarm during the alarm suppression period T (step S3) (step S4).
[0019]
In step S1, when the second sensor unit 2a does not detect a human body and the alarm suppression period T has elapsed (step S3), if the first sensor unit 1a detects a human body (step S5), the microcomputer 20a Based on the detection signal, while the sensor output interval t continues within a predetermined specified time, it is regarded as one sensor detection period and the sensor detection period is measured (step S6). When the sensor detection period is less than 5 seconds (step S7), the process returns to step 5 and measurement of the sensor detection period is continued.
[0020]
If the sensor detection period is 5 seconds or longer (step 7), the microcomputer 20a clearly determines that there is an intruder from the outside, and the “ping-pong sound” / “dog cry” selected by the changeover switch SW2 An alarm sound of any timbre among “•“ alarm ”is output from the speaker SP via the acoustic circuit 20b (step S8).
[0021]
When the sensor detection period is less than 5 seconds and the detection signal from the first sensor unit 1a disappears, the process returns to the standby state (step S9).
[0022]
By providing step S7, an alarm is generated only when a person is clearly staying at the front door.
[0023]
Therefore, when the housekeeper goes out, the second sensor unit 2a first detects the housekeeper. Therefore, if the alarm suppression period T is set and is within the alarm suppression period T, the first sensor unit 1a detects the housekeeper. Even if it detects, since the alerting | reporting unit 2 does not perform alerting | reporting operation | movement, it can prevent unnecessary alerting | reporting operation | movement.
[0024]
Also, when the housekeeper is in the house or going out, the person H comes to the front door and stays for 5 seconds or more after the alarm suppression period T has elapsed after the second sensor unit 2a detects the housekeeper. For example, if “ping-pong sound” is selected with the changeover switch SW2, a ping-pong sound is generated from the notification unit 2, or if “dog cry” is selected with the changeover switch SW2, a dog cry is notified. It is generated from the unit 2 and can be thought of as having a dog in the room, so that intrusion of a vacant nest or the like can be prevented.
[0025]
Here, the timing at which the alarm sound of “dog squeal” is generated will be described with reference to FIG. The sensor output 100 of the sensor unit 1a in the detection unit 1 is output at random intervals under conditions such as a temperature difference from the detected human body and a passing speed. Receiving the sensor output 100, the microcomputer 20a in the notification unit 2 controls the acoustic circuit 20b so that an alarm sound 200 of "dog squeal" is generated in conjunction with the timing at which the sensor output 100 is generated. As a result, the alarm sound 200 of “dog squeal” is also output at random intervals in synchronization with the sensor output 100, becomes close to an actual dog squeal, and is not easily seen by the intruder H.
[0026]
When the changeover switch SW2 selects “ping-pong sound” or “alarm sound”, it is not necessary to output at random intervals unlike the case of “dog squeal”, so the sensor output 100 is used as a trigger. It is sufficient to output an alarm sound of a fixed phrase for a certain period.
[0027]
In this embodiment, the case where the intrusion warning device is attached to the entrance door D has been described as an example, but the installation site of the intrusion alert device is not limited to the entrance door D. Any member other than the entrance door D may be used as long as it is an opening / closing member that can be freely opened and closed in the opening provided in the window. For example, as shown in FIGS. An intrusion warning device may be attached to alert an intruder from the window. In other words, the intrusion warning device has the detection unit 1 as the outdoor side, the notification unit 2 as the indoor side, the window plate G sandwiched between the detection unit 1 and the notification unit 2, and the end of the window plate G in the sliding direction. It is attached to the window plate G in a state where the central piece 3a of the connecting portion 3 is sandwiched between the gaps with the window frame M.
[0028]
Since this intrusion warning device has a configuration in which the detection unit 1 and the notification unit 2 are connected by the connecting portion 3, it can be easily attached to the opening and closing members such as the entrance door D and the window plate G. Yes.
[0029]
The volume of the alarm sound is not limited to three levels, and may be two levels, for example, “OFF” and “ON”.
[0030]
Also, the types of alarm sounds are not limited to three, and may be, for example, only “ping-pong sounds” and “dog calls”.
[0031]
Further, in step 7 of FIG. 5, the detection period (5 seconds in the present embodiment) in which the first sensor unit 1a regards that a person has been detected is not limited to the set time of the present embodiment. As long as it can be determined that is at the entrance.
[0032]
