Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention discriminates a picking sound generated when a door is unlocked improperly, a glass cutting sound generated when a window glass is cut or broken, and an opening / closing signal issued when the door is opened / closed. The invention relates to a device for preventing picking crimes, cutting or destroying window glass, and opening and closing doors to prevent bandits from entering the room.

[0002]

2. Description of the Related Art A picking crime prevention device currently on the market is configured to give an alarm sound to an intruder when a picking operation is detected. Even with such a device, if an alarm sound is generated while a criminal is performing a picking operation, he or she may be surprised and abandon the intrusion, and some effects can be expected. In addition, there is no end to the bandits who invade by cutting the window glass with a cutter, or when the bandits forgot to lock the door or the bandits open and open the door by skillfully unlocking the key by picking. is there.

[0003]

However, even in the case of the conventional crime prevention device, when there is a large amount of noise in the surroundings, the volume of the alarm sound generated by the buzzer is less noticeable even if there are people in the vicinity, and intruders do not notice it. Is not effective enough to prevent people from entering the room. In reality, it is said that it takes about 10 to 20 seconds for a criminal to unlock by picking, and during this period, unless an alarm sound is noticed and a person approaches, etc., Criminals can enter the room, switch off the alarm, or if destroyed, can enter the room without any problems. In some cases, waiting for the room owner to return home may cause personal injury. When a bandit uses a cutter to cut the window glass, he presses a suction cup against the glass near the window lock and cuts the area around it with a cutter, and the glass is cut off while adhering to the suction cup. Will end up. The bandit puts his hand through the hole, unlocks the window, opens the window, and enters the room. In addition, the bandits open the front door lock silently,
If the room owner forgets to lock the door and goes out, the room owner who returns home has no way of knowing whether or not an abnormality has been detected until he opens the door and enters the room. If a criminal is waiting in the room, it is too late at the time of entering the room. Thus, effective crime prevention measures are not possible with current devices. That is, in order to obtain a sufficient crime prevention effect against picking, intrusion from a window or a door, or a crime, it is necessary to detect a door unlocking sound, determine whether the sound is a picking sound, or a sound of cutting a window glass. It is desirable to have a function that issues an alarm only when it is judged as an abnormal signal from the destruction sound and the door opening / closing signal, and can confirm whether there is an abnormality before entering the room when coming home from the outside .

The present invention adds a function that is lacking in a conventional security device such as picking, and emphasizes the safety of oneself. Furthermore, it is also possible to make a configuration in which a mobile phone reports to a designated place when an abnormality occurs and the inside of the room at that time is monitored. That is, an object of the present invention is to provide a crime prevention device provided with various functions as described above and not only for picking but also for bandits invading through a window or a door.

BEST MODE FOR CARRYING OUT THE INVENTION Regarding one embodiment of the present invention,
A description will be given with reference to the drawings.

FIG. 1 (a) shows the indoor side of a door 1 having a normal structure attached to the entrance of a house or the like, and FIG. 1 (b) shows the outdoor side thereof. A knob 11 and a door lock 12 for locking the door 1 so as not to be opened when going out. In the crime prevention device of the present invention, the door lock 12 provided on the door 1 detects noise such as a scratching sound generated by an operation by a third party who attempts illegal intrusion to unlock by picking, The door 1 is equipped to prevent crime damage by the operation described below. The security device includes an indoor unit 3 arranged on the door 1 at a position close to the upper end on the indoor side of the door 1, and an outdoor unit 4 arranged on the outdoor side of the door 1 at a position corresponding to the indoor unit 3. The flat cable 5 is arranged so as to reach the outdoor unit 4 across the upper end of the door 1 from the indoor unit 3. The flat cable 5 includes an indoor unit 3 and an outdoor unit 4.
Are connected to each other's electrical circuits.

As shown in FIGS. 2 (a) and 2 (b), the indoor unit 3 has a switch 31 for controlling the operation of the picking crime prevention means, an indoor pilot lamp 32, and a battery in and out from the front thereof. In this case, a battery cover 33 that can be removed is provided. In this example, the switch 31 selects one of an “outgoing” position for operating the device when going out, an “OFF” position for inactivating the device, and a “test” position for performing an operation test of the device. Can be switched to. The outdoor unit 4 is
An electronic circuit connected to the electronic circuit of the indoor unit 3 via the flat cable 5 is housed, and an outdoor pilot lamp 41, a buzzer 42, and a remote control signal receiving section 43 are provided on the front surface thereof. The outdoor pilot lamp 41 emits green light under normal conditions and red light under some abnormal conditions. Further, FIG. 3 shows a remote control unit 6 for transmitting a remote control signal to the outdoor unit 4.
Is shown. This remote control unit 6 is carried by an administrator who manages the picking crime prevention device, and has a reset button 61 that is pressed when releasing the state in which the occurrence of picking is detected.

Next, a series of operations of the picking prevention means having the above structure will be described with reference to the flowchart of FIG. When the administrator goes out, the security device enters the operating state by switching the switch 31 of the indoor unit 3 to the "go out" position in step S1, and first checks the remaining battery level (step S2). At this point, if the battery level is less than the specified value, the buzzer equipped in the indoor unit 3 generates an alarm sound (step S3), and at the same time, the indoor pilot lamp 32 blinks to replace the battery. Urge. On the other hand, if the battery level is sufficient, the indoor pilot lamp 32 lights up in green (step S6), and at the same time, the outdoor pilot lamp 41 of the outdoor unit 4 lights up in green, indicating that the normal standby state has been entered. indicate. In this standby state, when the microphone in the crime prevention sensor provided in the indoor unit 3 detects the vibration sound of the door 1 (step S
7) The determination means determines whether this vibration sound is a normal vibration sound such as a knock or a vibration sound when the door lock 12 is picked. If the vibration sound applied to the door 1 is caused by, for example, a normal knock, the vibration for a short time is repeated only a few times, but the picking is performed by using a tool such as a pin on the cylinder of the door lock 12. Since it is a scratching operation using, it can be clearly distinguished from a normal vibration sound such as a knock. When the microphone in the security sensor continuously captures the vibration sound for 3 seconds or more, the determination means determines that the vibration sound is vibration due to picking (step S8). It should be noted that when the microphone in the security sensor does not detect vibration noise, it is checked whether the door sensor in the security sensor is ON (step S
9), and whether or not the operation by the remote controller described later is ON (step S15). If the microphone in the security sensor continuously senses vibration noise for 3 seconds or more and the door sensor in the security sensor is ON, it is determined that picking is being performed, and the outdoor unit Buzzer 4 of 4
2 generates an alarm sound (step S10), and at the same time, the outdoor pilot lamp 41 changes to red to notify that there is an abnormality (step S11). After that, if the microphone in the security sensor continues to sense the picking sound for a predetermined time (step S12), the buzzer 42 of the outdoor unit 4 generates an alarm sound, which is further sensed by the security sensor. Thus, the alarm sound is continuously generated for a predetermined time (for example, 5 seconds). With the alarm sound emitted from this buzzer 42,
Makes an intruder attempting an illegal intrusion dangerous and encourages them to stop picking and escape. When illegal picking is performed and then left unattended, the alarm sound from the buzzer 42 is stopped, but the outdoor pilot lamp 41 of the outdoor unit 4 remains lit in red. Therefore, even an administrator who does not know that picking has been performed can know that picking has been performed because the outdoor pilot lamp 41 is lit in red, and an intruder who enters the room carelessly It is possible to prevent damage such as being harmed by people. When the reset button 61 of the remote control unit 6 shown in FIG. 3 is pressed in this state, the remote control unit 6 transmits an infrared remote control signal to the remote control signal receiving section 43 of the indoor unit 4 (step S14). As a result, the alarm state of the indoor unit 3 is reset and the outdoor pilot lamp 41 goes out. Further, in the standby state, when the vibration sound sensor attached to the window glass detects the vibration sound or the destruction sound of the glass cut, the determination unit determines whether this vibration sound is a normal vibration sound or the glass cut or Determine whether it is an abnormal vibration sound generated by destruction. In this judgment, the vibration sound pattern due to cutting and destruction is more important than the duration,
Judgment based on patterns is used. In the case of an abnormal vibration sound, the buzzer is turned on (step S10), the outdoor lamp lights up in red (step S11), and the abnormality is informed. Even if the picking cannot be detected, when the door is opened or closed, the door open / close sensor in the security sensors attached to the door detects the open / close and the buzzer turns on.
(Step S10), the outdoor lamp lights up in red,
Notify that there is an abnormality. This is because even if the room owner forgets to lock the door when going out,
It is possible to know whether there is an abnormality and to secure personal safety.

[0010]

As described above, the device of the present invention detects the unlocking sound by the security sensor, and the internal control means,
There was an abnormality even if it was a picking vibration sound, whether it was a window glass cutting sound or a breaking sound, and when you go out and forget to lock or cannot detect picking. Occasionally, when an alarm is issued, you can check whether there was an abnormality before entering the room when coming home from the outside, and when an abnormality is confirmed, not only give an alarm sound to the intruder but also enter the room. However, even if the alarm is switched off or the device is destroyed, when the room owner returns home, the abnormality is immediately noticed, so the room owner does not directly enter the room, but first enters the police officer. Since you can take safe measures such as entering the room after receiving it, you can ensure your personal safety.
