Various devices and instruments have been proposed as crime prevention devices at night and in dark places like the automatic lighting device mentioned as an example. However, at construction sites and blind spots of buildings, crime prevention measures are not taken much like ordinary houses, and the crisis management situation must be clearly flawed.
For example, various equipment such as large heavy machinery and reinforcing bars remain on the construction site at night, which is an intrusion prohibited area. Nevertheless, there are many cases where there is no resident to manage, and if there is an intruder, the discovery is expected to be difficult or extremely delayed, and anyone can easily intrude if they are concerned It is in a state. In addition, when a building blind spot is reached, it is a danger zone where crimes such as molesting and arson are likely to occur frequently, especially in dark hours such as at night.

Against this background, effective crime prevention measures are urgently required particularly at night in construction sites and in blind spots of buildings. However, although there are awareness and necessity for crime prevention, there is no effective existing means (device), and no concrete measures have been taken.
For example, when trying to install an existing automatic lighting device by diverting it to a construction site or blind spot of a building, first of all, it was relatively easy to secure a power source at the entrance or garden, but construction When it is a blind spot of a site or a building, there is a problem that it becomes difficult to secure (supply) power.
In addition, as described above, automatic lighting devices are often seen at the entrances and gardens of ordinary houses, but recently intruders have become accustomed to this light warning, and the intimidating effect has become effective. It cannot be denied that it has been reduced. In this case, a sufficient effect cannot be expected only by diverting the existing automatic lighting device.
In addition, a temporary scaffold or the like at a construction site repeats assembly and disassembly many times at regular intervals. For this reason, if a complicated work is required for installing the automatic lighting device, it is troublesome for the worker and an extra burden, which cannot be put into practical use.
Furthermore, even if an existing automatic lighting device can be installed in the blind spot of a construction site or building, when the lighting is turned on by detecting a human body reaction such as an intruder, it is possible to determine where the surrounding light is shining. It can be difficult, and as a result, the discovery of intruders and criminals can be delayed, leading to further serious incidents.
As described above, there are many aspects that are insufficient to use the existing automatic lighting device as a crime prevention device for intruder countermeasures at a construction site or a blind spot of a building, and various difficulties are involved. Yes.

Hereinafter, an embodiment of a security device according to the present invention will be described with reference to the drawings.
FIG. 1 is a (a) side view and (b) bottom view of a security device according to the present invention. FIG. 2 is a flowchart showing an example of the operation of the security device.
The security device 10 includes an illuminating lamp 12 as an issuing means, a speaker 14 as a sound generating means, an optical sensor 16 as an illuminance detecting means, a human sensor 18 as a human body detecting means, a control circuit 20 for controlling them, a housing 22 and a magnet 24 as an attaching means. A battery 26 serving as a power source is accommodated in the security device 10. Further, at the lower part of the security device 10, various adjustment means of a light sensor sensitivity adjustment knob 28, a human sensor sensitivity adjustment knob 30, a speaker volume adjustment knob 32 and a speaker changeover switch 34 connected to the control circuit 20, and a reset button 36. It has.

  The illumination lamp 12 is configured to light up or blink when a human body is sensed by a human sensor 18 described later. It is preferable to arbitrarily set the lighting (flashing) time within a range of about 2 seconds to 10 minutes. The lighting (flashing) time and lighting (flashing) pattern may be arbitrarily adjusted. For example, it can be set to light for 10 seconds after flashing for 10 seconds. As the illumination lamp 12, for example, a light emitting diode, a fluorescent lamp, a light bulb, or the like can be used. The illuminating lamp 12 is arranged in a conspicuous place where it can be visually recognized. For example, it is preferable to arrange | position to the upper part of the main body of the crime prevention instrument 10 like a present Example. The illuminating lamp 12 can emit two types of light, strong light and weak light, by the control means 20. The two types of light may be changed by providing two types of light sources or changing the voltage. While the human sensor 18 detects a human body within a predetermined distance, strong (bright) light is emitted from the illuminating lamp 12, and when the human sensor 18 detects that the human body is separated from the predetermined distance. The illumination lamp 12 may be set to emit weak light.

  The speaker 14 is configured to emit an alarm sound (warning sound) for a predetermined time when a human body is sensed by a human sensor 18 described later. The volume of the alarm sound can be arbitrarily adjusted by the speaker volume adjustment knob 32, and can also be set so as not to be sounded by the speaker changeover switch 34 (OFF). The alarm sound may be sounded simultaneously with the light of the illuminating lamp 12, or may be sounded with a slight shift before or after the light. While the illuminating lamp 12 is lit (flashing), it may continue to sound or may end before or after the light. Further, the alarm sound pattern may be arbitrarily switched, and the alarm sound pattern may be changed in conjunction with the illumination lamp 12. For example, the alarm sound A may be used when the light is on, and the alarm sound B may be used when the light is flashing. In addition, it is preferable that the speaker 14 is installed in the lower part of the main body of the security device 10 as in this embodiment, and the periphery thereof is covered with a cover 38 so as not to be exposed to wind and rain. The control means 20 may be configured to switch and generate two different types of different sounds such as a relatively loud sound and a relatively small sound. In that case, while the human sensor 18 detects the human body within a predetermined distance, one of two types of sounds such as a relatively loud sound is generated from the speaker 14, and the human sensor 18 is predetermined. When it is detected that the human body has moved away from within the distance, another one of two types of sounds such as a relatively small sound is generated from the speaker 14.

  The optical sensor 16 detects the brightness around the security device 10 and plays the role of a timer that distinguishes day and night. That is, when the ambient illuminance detected by the optical sensor 16 is equal to or lower than a predetermined illuminance set in advance, the human sensor 18 described later is operated. As a result, since the human sensor 18 is not activated when it is bright during the daytime or the like, the illumination lamp 12 is lit (flashes) or an alarm sound is emitted from the speaker 14 even when a person approaches the security device 10. There's nothing to do. The optical sensor 16 can adjust the light receiving sensitivity with the optical sensor sensitivity adjustment knob 28. That is, it is possible to adjust how much brightness (darkness) the human sensor 18 is to activate. Moreover, a semitransparent seal or the like may be attached to adjust the light receiving sensitivity. In addition, it is preferable that the optical sensor 16 is attached so as not to be affected by the light of the illumination lamp 12.

  The human sensor 18 detects a human body approaching the security device 10 based on temperature or the like. For example, the human sensor 18 detects a change in the amount of heat generated by the movement of a person, but is not limited thereto. As described above, by interlocking with the optical sensor 16, it does not operate when it is bright such as daytime, but operates only in dark time zones such as night or dark places and reacts to the human body. The detection angle is preferably a horizontal spread angle of about 200 degrees to about 270 degrees, for example, about 220 degrees. In addition, the detection distance can be detected up to 5 meters away, but it is preferable to dare to narrow the range to reduce malfunctions. For example, it may be about 1 m. The detection range (detection angle / detection distance) may be arbitrarily adjusted and set each time. The human sensor 18 can adjust the detection sensitivity by the human sensor sensitivity adjustment knob 30. That is, it is possible to adjust the accuracy of how much temperature change is recognized. The human sensor 18 is preferably attached at a relatively high position so as not to react with small animals.

The crime prevention instrument 10 in the present embodiment is mainly operated with the battery 26 accommodated therein as a power source. Since the power supply is integrated as described above, a separate external power supply is not required, and a power cord and an outlet are not required, and wiring work during installation is also unnecessary. However, when the security device 10 is installed in a garden or the like, an AC power source can be used.
In the present embodiment, the magnets 24 are installed at two locations as attachment means, but any means that can be easily attached may be used. For example, it is possible to attach to any outer wall by using a screw or the like in addition to the magnet 24.

  The reset button 36 provided at the lower part of the security device 10 is connected to, for example, a reset switch (not shown) included in the control circuit 20. It is set so that the human sensor 18 operates normally again after a lapse of time. If the human sensor 18 is not activated after a certain time has elapsed, the human sensor 18 is activated before the person who presses the reset button 36 leaves the crime prevention device 10. It is.

  In addition, since the daylight time in summer is long, it becomes bright early in the morning, so that the security device 10 does not operate early in the morning at a construction site or the like. There is a time of several hours from when the operation stops until the worker arrives, and during that time, an intruder may enter the construction site or the like. Therefore, sound may be generated from the speaker 14 when the presence of a person within a predetermined distance is detected by the human sensor 18 for a certain time after the optical sensor 16 stops working. The sound from the speaker 14 generates one of two kinds of sounds such as a relatively loud sound from the speaker 14 while the human sensor 18 detects the human body within a predetermined distance. When 18 detects that the human body is separated from within a predetermined distance, it is desirable to generate another type of sound, such as a relatively low level, from the speaker 14. This makes it possible to find an intruder even during a bright time.

An example of operation | movement of the crime prevention instrument 10 in a present Example comprised as mentioned above is shown below. Here, it is assumed that it is installed in a temporary scaffolding at a construction site or a blind spot of a building that is a night entry prohibition area.
As shown in FIG. 2, first, the brightness around the security device 10 is determined by the optical sensor 16 (step 1). If the ambient brightness detected by the optical sensor 16 is less than or equal to a predetermined illuminance set in advance, the human sensor 18 is activated to determine whether there is an intruder (human body) (step 2). If the presence sensor 18 detects the presence of an intruder, the illumination lamp 12 is turned on or blinked (step 3). At this time, the ON / OFF setting of the speaker 14 is determined (step 4), and if it is ON, an alarm sound is generated from the speaker 14 (step 5).
When an intruder is detected and the illuminating lamp 12 (and the speaker 14 in some cases) is activated and a predetermined time elapses (step 6), the light is extinguished and silenced (alarm sound is terminated) (step 7).

  In addition, the flow of the said process is an example of operation | movement of the crime prevention instrument 10 in a present Example. Therefore, it is also possible to operate the security device 10 according to other processing orders and processing patterns. For example, since the light from the illuminating lamp 12 and the alarm sound from the speaker 14 can be generated or shifted simultaneously, the processing order of Step 3 to Step 5 can be changed as appropriate. In addition, since the lighting (flashing) time and the alarm sounding time can be changed, if the lighting (flashing) time and the ringing time end time are different, the processing of step 6 and step 7 is divided separately. You can also.

FIG. 3 is a flowchart showing an example of the operation when the crime prevention instrument 10 is provided with a timer, which is a time measuring means, instead of the optical sensor 16.
A timer (not shown) as a time measuring means plays a role substantially similar to that of the optical sensor 16 described above, and activates the human sensor 18 at a predetermined time or an arbitrary time set in advance. is there. For example, as shown in FIG. 3, the current time is determined by a timer (step 1), and if the current time is between 19:00 and 5 o'clock, the human sensor 18 is activated to check for the presence of an intruder (human body). Judgment is made (step 2). At this time, the time zone in which the human sensor 18 is operated can be freely set. For example, if the summer sunshine time is long, it is set to 19:00 to 5:00, and if the winter sunshine time is short, It can also be set like 17:00 to 7:00. The time measured by the timer may be not only the current time but also the elapsed time. For example, the human sensor 18 may be activated when a timer is set, and the human sensor 18 may be set to automatically turn off after 10 hours. In addition, you may provide the part (for example, liquid crystal panel etc.) which displays the present time, elapsed time, etc. which are measured by the time measuring means.
Since other configurations and operations are the same as the configurations and operations of the security device 10 provided with the above-described optical sensor 16, detailed description thereof is omitted.

    Moreover, the optical sensor 16 and a timer can be provided side by side. By adopting such a configuration, it is possible to cope with changes in daylight hours in summer and winter. For example, during summer hours with long hours of sunshine, it can be assumed that even in the construction site, even if the evening work ends and there are no workers on the site, the crime prevention device 10 does not operate because it is still bright. However, if the timer and the optical sensor 16 are linked, it is possible to cope with such a situation.

As described above, when the optical sensor is installed, the optical sensor 16 and the human sensor 18 are linked to each other, and when the brightness falls below a predetermined brightness (if the timer is installed, the timer and the human sensor 18 are linked. When the human sensor 18 is activated and the presence of an intruder is detected by the human sensor 18, a light and a sound are generated. In addition to threatening intruders, the presence of the intruder can be notified to the surroundings. That is, since the light and sound warning can be expected to produce a synergistic effect between vision and hearing, the psychological pressure given to the intruder is great. In addition, the surrounding third party can recognize the abnormality by the sound and can visually recognize the light, so that the position information of the intruder can be recognized quickly.
The intruder here is assumed to be a malicious intruder in general, and includes, for example, a person who is trying to commit a criminal act such as a molester or arson. The surroundings include a large number of external unspecified persons, that is, managers and security guards who rushed to, as well as third parties in the vicinity.

By arranging a plurality of the security devices 10 having the above-described configuration and the above-described operation, further effects are generated. Hereinafter, a preferable arrangement example in the case where a plurality of security devices 10 are installed in a temporary scaffold (predetermined area) at a construction site that is a night entry prohibition area will be described. Here, it is assumed that the security device 10 warns with both the light 42 and the alarm sound 44.
FIG. 4 is a configuration diagram showing an example of an arrangement structure of the security device. As shown in FIG. 4, for example, the security devices 10 are installed at predetermined intervals at four locations on the temporary scaffold. Assume that each security device 10 is a first security device 110, a second security device 210, a third security device 310, and a fourth security device 410, and the distance between adjacent security devices 110 to 410 is about 5 m.

  When an intruder 40 enters this area at night, the presence is first detected by the first security device 110. The first security device 110 that has detected the presence of the intruder 40 warns both the intruder and the surrounding area with both the light 42 and the alarm sound 44 as described above. If the surprised intruder 40 moves to the warning, it enters the detection range of the adjacent second security device 210 next. The second security device 210 that has detected the intruder 40 also gives a warning by the light 42 and the alarm sound 44. At this time, while the first security device 110 is detecting, the warning by the light 42 and the sound 44 by the first security device 110 continues, but the intruder 40 has moved, so the first security device If it is out of the detection range, a warning by the weak light 42 and a small alarm sound 44 may be issued for a predetermined time even when the warning by the first crime prevention instrument 110 ends. Similarly, when the intruder 40 further moves, a warning is started in order of the third crime prevention device 310 and the fourth crime prevention device 410, and as the intruder 40 moves, the second crime prevention device 213, the third crime prevention device. The warning is ended or reduced in order after 310.

  Thus, according to the arrangement structure in the present embodiment, each security device 110 is tracked so that the intruder 40 is tracked as the intruder 40 moves by linking the first security device 110 to the second security device 410. ˜410 operate sequentially. Accordingly, the light 42 and the sound 44 can be tracked as the intruder 40 moves, and the intruder 40 feels as if the light 42 and the sound 44 are chased no matter where he / she escapes. Increases further. In addition, the surrounding third party can immediately recognize the current position of the intruder from the locus of the light 42 accompanying the movement of the intruder 40, strong light, and, for example, a loud sound.

  If the security device according to the present invention is installed in a place where night security is required, such as a temporary scaffold at a construction site or a blind spot of a building, an intruder will threaten in a form that causes great anxiety and threat and against the surroundings However, since the presence of the intruder can be informed, the intrusion of illegal intruders can be prevented.
