Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crime prevention device with a crime prevention function which detects an intruder in a predetermined warning area and eliminates it by performing a crime prevention operation such as spraying tear gas. .

[0002]

2. Description of the Related Art As an example of a conventional crime prevention device, a sensor detects an intruder who has entered a predetermined warning area, and an alarm device is activated in response to the detection. Things are known. However, in the crime prevention device having such a configuration, an alarm is issued from the alarm device, and it takes a certain amount of time for the guard to rush to the scene, so the crime is completed before the guard arrives at the scene, Intruders were often found to have already escaped, and they were sometimes unable to perform sufficient crime prevention.

In order to solve such a problem,
There has also been proposed a device provided with a crime suppressing means for spraying a tear gas or an offensive odor gas or the like in response to the detection of a sensor to disperse an intruder (Japanese Utility Model Publication No. 57-92288).
However, with such a configuration, rather than an intruder,
For example, even if a person who installs a crime prevention device or a person related to a building (hereinafter, simply referred to as “person concerned”) accidentally enters the warning area, the crime deterrent means is activated and the person enters. May injure related parties.

Therefore, the present invention has a sufficient crime deterrent function against an intruder, and can prevent damage by a crime deterrence means such as tear gas even if a person involved in the crime prevention device accidentally enters the security area. An object is to provide a security device with a function.

[0005]

In order to achieve the above-mentioned object, a crime prevention device with a crime suppressing function according to a first configuration of the present invention includes a sensor section for detecting a human body in a predetermined warning area, and the sensor. A warning unit that generates a sound or light based on the detection by the unit to give a warning for a certain period of time, and a high-volume sound when the sensor unit detects within a predetermined time after the start or the end of the warning, The crime suppressing unit that performs a crime suppressing operation by generating a large amount of light or a medium that directly acts on a human body is provided. Here, "medium that directly acts on the human body" includes substances that adhere to the human body, such as paint or marker liquid that attaches odors, as well as tear gas, odorous gas, and human bodies such as smoke that obstructs visibility. The physical ones that affect the various organs of the human body, or the electrical ones such as a large electric current that gives an electric shock to the human body are also included.

In the security device, when an intruder enters a predetermined warning area, the sensor unit detects the intruder, and in response to this, the alarm unit generates sound or light to warn for a certain period of time. If the intruder does not leave after the warning is over,
Since the sensor unit detects an intruder within a predetermined time after the end of the warning, the crime deterrent unit generates a loud sound, a large amount of light, or a medium that directly acts on the human body in response to this, and thus the crime prevention unit commits a crime. Intruders can be eliminated by performing deterrent actions. This crime suppressing operation is a so-called threatening or repulsing operation.

Even when a person who installs a security device or a person involved in a building accidentally intrudes into the guard area instead of an intruder, the sensor unit detects and the warning unit warns for a certain period of time. A person concerned can escape from the crime deterrence operation of the crime deterrence unit that operates next by leaving the guard area while the warning is being issued.

A crime prevention device with a crime suppressing function according to a second aspect of the present invention is a first sensor for detecting a human body in a first warning area near a crime prevention object and a first sensor outside the first warning area. 2 A sensor unit having a second sensor for detecting a human body within the warning area, a warning unit for generating a sound or light based on the detection by the second sensor to give a warning for a predetermined time, and a detection by the first sensor When there is a crime, a crime deterrence unit that performs a crime deterrence operation by generating a loud sound, a large amount of light, or a medium that directly affects the human body is provided.

In the crime prevention device, when an intruder enters the second security area outside the first security area, the second security area
The sensor detects, and in response to this, the warning unit generates a sound or light to warn for a certain period of time. When the intruder does not disperse due to the warning and enters the first warning area near the crime prevention object, the first sensor detects this and in response to this, the crime prevention unit makes a loud sound, a large amount of light. Since the crime deterrent action is performed by generating a light or a medium that directly acts on the human body, an intruder can be excluded.

Even when the person installing the security device or the person involved in the building accidentally intrudes into the second warning area, not the intruder, the second sensor detects this and the warning unit warns for a certain period of time. However, in this case, a person concerned can escape from the crime suppressing operation of the crime suppressing unit that operates next by hearing the warning and escaping from the second warning area.

A crime prevention device with a crime suppressing function according to a third structure of the present invention includes a first sensor for detecting a human body in a first warning area near a crime prevention object, the first warning area and the outside thereof. A sensor unit having a second sensor for detecting a human body in a second warning area including the alarm unit; and a warning unit for generating a sound or light based on the detection by the second sensor to give a warning for a certain period of time; A crime deterrence unit that performs a crime deterrence operation by generating a loud sound, a large amount of light, or a medium that directly acts on the human body when detected by the second both sensors is provided.

In the security device, when an intruder enters the first security area near the security object and the second security area including the outside thereof, the second sensor detects the intruder and sends a warning in response. The unit emits sound or light and warns for a certain period of time. If the warning doesn't dissipate the intruder,
At the time when the intruder moves from the second warning area to the first area, both the first and second sensors detect the intruder, and in response to this, the crime prevention unit makes a loud sound or a large amount of light. An intruder can be excluded because a crime suppressing operation is performed by generating light or a medium that directly acts on the human body.

Even when a person who installs the security device or a person involved in the building accidentally enters the second warning area instead of an intruder, the second sensor detects the warning and the warning unit warns for a certain period of time. In this case, a person concerned can escape from the crime suppressing operation of the crime suppressing unit that operates next by hearing the warning and escaping from the second warning area.

In addition to the crime prevention device having the crime prevention function of each of the above-mentioned structures, an impact sensor for detecting the impact applied to the device body accommodating the sensor portion, the warning portion and the crime prevention portion and operating the crime prevention portion. Is preferably provided.
In order for an intruder to stop the operation of the security device, the intruder may try to destroy the security device with a hammer etc. before the alarm is issued and the alarm is still issued. When the device body is hit, the impact sensor detects the impact applied to the device body and activates the crime prevention unit, so that an intruder can be eliminated.

In the crime prevention device with the crime suppressing function of each of the above-mentioned constitutions, the medium directly acting on the human body is tear gas, odorous gas, smoke obstructing the field of view, paint or a marker liquid for attaching odor, and electric shock. It is preferable that at least one of the large currents to be applied is generated.

[0016] When the crime deterrent unit generates a tear gas or an odorous gas, the invader cannot open his eyes or breathe because of the gas, so that the crime prevention object should be protected. Since it is difficult to carry out the purpose of stealing, it is highly effective in dispelling intruders. When the crime suppression unit generates smoke that obstructs the field of view, the smoke deteriorates the field of view, and it is difficult to carry out the purpose of stealing the crime prevention target, so that it is highly effective in retreating intruders. When the crime suppression unit generates paint or a marker liquid that attaches odor, when the paint or marker liquid adheres to the intruder, the adhered paint or marker liquid is used as evidence, or Easily tracked as a sign, it is highly effective in dispelling intruders. If the crime deterrent unit generates a large electric current that gives an electric shock, it will cause pain to the intruder due to electric shock (electric shock).
Highly effective in dispelling intruders.

In the crime prevention device having a crime suppressing function having the above-mentioned structure, the crime suppressing unit may generate tear gas, odorous gas or smoke obstructing the field of view and loud sound.

With such a structure, when an intruder opens a window to exhaust tear gas or smoke to the outside,
Since a loud sound also echoes outdoors, it will be noticed by an outsider, and the effect of dispersing an intruder becomes higher.

A crime prevention system according to the present invention comprises a master unit including the crime prevention device of the present invention, and a slave unit of the crime prevention device of the present invention including a crime suppressing unit and excluding a sensor unit. Is provided with a transmitter on the base unit side that transmits an activation signal when the sensor unit detects that the crime prevention unit is to be activated. A slave side receiver for operating the crime suppression unit is provided.

In this crime prevention system, the crime suppression unit of the master unit operates based on the detection by the sensor unit of the master unit, and the activation signal transmitted from the transmitter of the master unit is received by the receiver of the slave unit. Then, the crime prevention unit of the child machine also operates. Therefore, for example, when the room to be monitored is large, if the main unit and the slave unit are installed at multiple locations in the room, a medium for crime control such as tear gas can be quickly provided in the room. Can be filled up, and the effect of dispelling intruders is improved.

[0021]

Preferred embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of a crime prevention device with a crime suppression function according to a first embodiment of the present invention. This crime prevention device is a charger that supplies DC power to each part of the device through a sensor unit 1, a warning unit 2, a crime suppression unit 3, a control unit 4, a transmitter 5, a receiver 6, an impact sensor 21, and a control unit 4. Power supply 2 like a battery
2, and an output terminal 24 for automatic notification to the outside which is used as needed.

The sensor unit 1 detects a human body in a predetermined warning area A, and is provided with a passive infrared detector that receives infrared rays from the human body and operates.

The warning unit 2 is means for generating a sound or light based on the detection by the sensor unit 1 to give a warning for a certain period of time. In the case of a sound, a predetermined warning sentence is issued by a voice synthesizer, for example. It is the alarm voicing device 20 that does. The crime suppression unit 3 has a predetermined time T (for example, 5 after the end of the warning).
When the sensor unit 1 detects within a second), it is a means for performing a crime suppressing operation by generating a loud sound, a large amount of light, or a medium that directly acts on the human body. A spray device for spraying is used. This spray device is configured so that a nozzle 9 of a spray can 7 filled with a liquefied gas of tearing gas is pushed by a driver 10 such as an electromagnetic actuator to spray. Other than the above, the substance to be sprayed may be an odorless gas or smoke that obstructs the field of view, and may be a paint or a marker liquid to which odor is attached. Instead of the electromagnetic actuator, the driving machine 10 may have another structure such as a mechanism including a spring, a stopper, and an electromagnet for driving the stopper.

The impact sensor 21 is a device body 30 comprising a case in which a sensor unit 1, a warning unit 2, a crime prevention unit 3, a control unit 4, a receiver 6, a power source 22 and an output terminal 24 are housed.
On the other hand, when an impact is applied from the outside, it detects the impact and outputs an impact detection signal, and is composed of a detector such as an acceleration sensor that detects vibration. The crime prevention unit 3, that is, the spray devices 7, 9 and 10 are housed and protected in the protective case 32 so as not to lose their functions due to the impact.

The control section 4 is means for controlling the sensor section 1, the warning section 2, the crime prevention section 3 and the impact sensor 21, and is constituted by, for example, a microcomputer or the like. The transmitter 5 is a means for wirelessly transmitting an on / off command signal to the receiver 6, and has a portable size and shape. The receiver 6 receives the ON / OFF command signal and receives the ON / OFF command signal.
Is a means of turning on and off. When the control unit 4 is turned on,
The sensor unit 1, the warning unit 2, the crime prevention unit 3, and the impact sensor 21 are in a standby state. When the control unit 4 is turned off, the sensor unit 1, the warning unit 2, the crime suppression unit 3 and the impact sensor 21 are stopped.

FIG. 2 shows a timing chart of the operation of the security device. Referring to this timing chart,
The operation of the security device will be described below. When the installation place of the security device is unattended, the user wirelessly transmits the ON command signal a from the transmitter 5 (FIG. 2 (A)). Upon receiving this ON command signal, the receiver 6 turns on the control unit 4. As a result, the sensor unit 1, the warning unit 2, the crime suppression unit 3, and the impact sensor 21 are put into the standby state by the control unit 4. In this standby state, when an intruder enters a predetermined area A, which is a warning area of the sensor unit 1, the sensor unit 1 detects this and outputs a detection signal (FIG. 2B) b.
In response to the detection signal b, the control unit 4 outputs the warning command signal d, and the warning unit 2 is operated for a fixed time t1 (for example, 10 to 20 seconds). As a result, the warning unit 2 continues to issue a warning (FIG. 2C) by voice, for example, for the predetermined time t1. In addition, a new detection signal b is generated while the warning unit 2 is operating.
Even if occurs, the control unit 4 does not respond to this and the warning unit 2 continues to operate based on the first detection signal b.

The intruder is also alerted by the warning area A.
When the sensor unit 1 does not diverge from the
Continue to occur. When the sensor unit 1 detects an intruder within a predetermined time T (for example, 5 seconds) after the warning is finished, the control unit 4 causes the repulsion command signal e at the detection timing.
Is output and the crime suppression unit 3 is operated for a certain time t2 (for example, 20 seconds). That is, in this embodiment, the driving machine 10 operates and the tear gas is sprayed from the nozzle 9. Because of the tear gas, the intruder cannot keep his eyes open, and cannot carry out the purpose of stealing the security target. As a result, intruders can be excluded from the security area A. Further, the alarm command signal d and the repulsion command signal e from the control unit 4 are also input to the output terminal 24. When the output terminal 24 is connected to, for example, an external security center, the output terminal 24 is output. Sent to the security center.

If the sensor unit 1 does not detect an intruder within a predetermined time T after the end of the warning, the control unit 4
Resets the warning unit 2 to the state before the operation. As a result, the warning unit 2 returns to the original standby state together with the sensor unit 1 and the crime suppression unit 3.

The crime suppressing section 3 may generate a loud sound as shown in FIG. 2 (E) at the same time when the tear gas is generated. The generation time of the loud sound is a time t3 (for example, 5 minutes) sufficiently longer than the generation time of the tear gas (20 seconds).
Is preferred. In this way, if a loud sound is generated at the same time as the tear gas is generated, even if an intruder opens the window and exhausts the tear gas to the outside to escape from the pain of the tear gas, the loud sound is emitted from the opened window. The sound echoes outdoors,
Since the abnormality inside the room will be known to others outside, the intruder can be more surely dissipated as compared with the case of using the tear gas alone.

In the above-mentioned operation, even if, for example, an installer of this security device or a person involved in the building accidentally enters the security area A, the warning section 2 is activated and a warning is given for a certain period of time. In this case, the person concerned can escape from the crime suppression operation of the crime suppression unit 3 that operates next by leaving the inside of the warning area A while the warning is given.

Further, in this embodiment, the crime suppressing section 3 is configured to generate tear gas, but as described above, it generates a large volume sound, or generates a large amount of light, or The crime suppressing action may be performed by generating a substance other than the tear gas that directly acts on the human body. As a substance other than tear gas, for example, when an odorous gas is generated, its unpleasant odor makes it difficult to breathe. Is worse, and in any case, it is difficult to carry out the purpose of stealing the crime prevention object, so the effect of dispersing the intruder is high. If you use a combination of odorous gas or smoke that obstructs your view and one that produces a loud sound, the same as when you use one that produces a tear gas and one that produces a loud sound. , The effect of dispelling intruders can be increased.

Further, when a paint or a marker liquid to which odor is attached is generated as a substance other than the tear gas, when the paint or the marker liquid is attached to the invader, the attached paint or marker liquid is attached. The intruder can be easily traced because it can be easily traced by using it as evidence or by using this as a sign. Further, when the crime suppressing unit 3 that generates a large electric current that gives an electric shock is used, the intruder suffers from the electric shock, so that the effect of causing the intruder to escape is high. Note that some of these means given as specific examples of the crime suppression unit 3 may be used in combination. Further, in this embodiment, after the warning unit 2 finishes the operation for the fixed time t1, that is, after the warning, when the detection by the sensor unit 1 is performed within the predetermined time T, the crime suppression unit 3 is operated. Unlike this, the crime suppression unit 3 may be activated when the operation of the warning unit 2 is started, that is, when the detection by the sensor unit 1 is performed within a predetermined time (t1 + T) from the start of the warning.

FIG. 3 is a block diagram showing a schematic configuration of a crime prevention device with a crime suppressing function according to a second embodiment of the present invention.
In the figure, the same or similar components as those in the first embodiment are designated by the same reference numerals. In this security device, the sensor unit 1 detects the human body in the first warning area A1 near the security target 10 such as a safe.
1 and a second sensor 12 for detecting a human body in a second warning area A2 outside the first warning area A1. FIG. 4 shows a plan view of the first and second warning areas A1 and A2. Each of the sensors 11 and 12 is equipped with a passive infrared detector, and the detection area of each of the sensors 11 and 12 can be set by a Fresnel lens that constitutes the sensor.

The warning unit 2 generates a sound or light based on the detection by the second sensor 12 and outputs a sound or light for a predetermined time (for example, 8 seconds).
It is a means for giving a warning for a second), and the warning is generated by a voice, for example, by a voice synthesizer. The crime suppression unit 3 outputs a loud sound when the first sensor 11 detects the sound.
This is a means for performing a crime deterrent operation by generating a large amount of light or a medium that directly acts on the human body. Here, a spray device that sprays the same tear gas as in the case of the first embodiment is shown. Other configurations are similar to those of the first embodiment, and detailed description thereof is omitted here.

The operation of the security device will be described below with reference to the timing chart shown in FIG. When the ON command signal a (FIG. 5A) wirelessly transmitted from the transmitter 5 is received and the receiver 6 turns ON the control unit 4, the sensor unit 1,
The warning unit 2, the crime prevention unit 3, and the impact sensor 21 are put into a standby state by the control unit 4. In this standby state, the second warning area A2 outside the first warning area A1
When an intruder enters the inside, the second sensor 12 detects it and outputs a detection signal b2 (FIG. 5 (B)), and in response thereto, the control unit 4 outputs an alarm command signal d and outputs a warning. The part 2 is operated for a fixed time t1 (for example, 8 seconds) (FIG. 5 (C)). As a result, the warning unit 2 continues to issue a warning (FIG. 2C) by voice, for example, for the predetermined time t1. Even if this warning is issued, the intruder does not leave, and when the warning is issued, that is, if the intruder enters the first warning area A1 within a certain time t1, the first sensor 11 detects this and the detection signal b1 (FIG. 5 (D)). In response to this, the control unit 4 outputs a repulsion command signal e, and the crime suppression unit 3 is operated for a fixed time t2 (for example, 5 minutes) (FIG. 5 (E)). In this embodiment, the driving machine 1
0 operates and the tear gas is sprayed from the nozzle 9. Because of the tear gas, the intruder cannot keep his eyes open, and it is difficult to carry out the purpose of stealing the security target 10. Therefore, the intruder can be excluded from the security area.

Further, if the first sensor 11 does not detect an intruder during the warning, that is, if the intruder does not move from the second warning area A2 to the first warning area A1, the control unit is activated at the end of the warning. Reference numeral 4 resets the warning unit 2 to the state before the operation. As a result, the warning unit 2 is operated by the sensor unit 11,
12, the crime suppression unit 3 and the impact sensor 21 are returned to the original standby state. At this point, if the intruder has stopped in the second warning area A2, the second sensor 12 detects the intruder and the warning unit 2 is activated again.

Also in the case of this security device, the person who installs the security device or the person involved in the building is in the second warning area A2.
When it accidentally intrudes into the inside, the warning unit 2 is activated and a warning is given for a certain period of time. However, the related persons, etc. may leave the inside of the second warning area A2 while the warning is given. It is possible to escape from the crime suppression operation of the crime suppression unit 3 that operates next.

FIG. 6 is a schematic view showing the structure of the sensor section in the crime prevention device with crime suppressing function according to the third embodiment of the present invention. In this security device, part of the second warning area A2, which is the detection area of the second sensor 12, is
It is arranged so as to overlap the first warning area A1 which is the first detection area. That is, as shown in a plan view in FIG. 7, with respect to the first warning area A1 in the vicinity of the crime prevention object 10, the second warning area A2 is the entire first warning area A1 and the first warning area A1. The area includes the outer area.

Further, the warning unit 2 generates a sound or light based on the detection by the second sensor 12 and gives a warning for a predetermined time t1 (for example, 8 seconds) in the second embodiment shown in FIG. However, the crime suppression unit 3 is different from that of the second embodiment in that the crime prevention unit 3 is activated when detected by both the first and second sensors 11 and 12. Other configurations are similar to those of the second embodiment, and detailed description thereof will be omitted here.

The operation of the security device will be described below with reference to the timing chart shown in FIG. When the ON command signal a (FIG. 8A) wirelessly transmitted from the transmitter 5 is received and the receiver 6 turns ON the control unit 4, the sensor unit 1,
The warning unit 2, the crime prevention unit 3, and the impact sensor 21 are put into a standby state by the control unit 4. In this standby state, the second warning area A2 outside the first warning area A1
When an intruder enters the inside, the second sensor 12 detects it and outputs a detection signal b2 (FIG. 8 (B)). In response to this, the control unit 4 outputs an alarm command signal d and outputs a warning. The part 2 is operated for a fixed time t1 (for example, 8 seconds) (FIG. 8 (C)). As a result, the warning unit 2 continues to issue a warning (FIG. 8C) by voice, for example, for the predetermined time t1.

The intruder does not disperse even by this warning, and when the intruder moves from the second caution area A2 to the first caution area A1 during the warning, the second caution area A2 and the first caution area A1 overlap each other. When there is an intruder in the
Not only the sensor 12 but also the first sensor 11 detects this and outputs the detection signal b1 (FIG. 8 (D)). At this time, in response to the AND signal c (FIG. 8E) of the detection signals b1 and b2 of both the sensors 11 and 12, the control unit 4 outputs the repulsion command signal e, and the crime suppressing unit 3 is operated for a certain time. t2 (for example, 5
Operation) (FIG. 8 (F)). That is, also in this embodiment, the driving machine 10 operates and the tear gas is sprayed from the nozzle 9. Because of the tear gas, the intruder cannot keep his eyes open, and it is difficult to carry out the purpose of stealing the security target 10. Therefore, the intruder can be excluded from the security area.

During the warning, both the sensors 11, 1
When there is no detection by 2, the control unit 4 resets the warning unit 2 to the state before the operation when the warning ends. As a result, the warning unit 2 returns to the original standby state together with the sensor unit 1, the crime prevention unit 3, and the impact sensor 21. At this point, if the intruder is in the second warning area A2,
When the second sensor 12 detects this, the warning unit 2
Will work again.

Also in the case of this security device, when a person who installs the security device or a person involved in the building accidentally intrudes into the second warning area A2, the warning unit 2 operates and a warning is given for a certain period of time. The person concerned can escape from the crime suppressing operation of the crime suppressing unit 3 to be operated next, by escaping from the inside of the second warning area A2 while the warning is given.
