[0003]

The conventional system as described above has a problem that the system becomes complicated because it must be separated for each genre. Further, since each device is connected by a plurality of wirings, there is a problem that the wiring becomes complicated. An object of the present invention is to provide a crime prevention / disaster prevention system which is a simple system and does not require special wiring.

[0004]

A first invention comprises a human sensor, a thermal sensor, a gas / smoke sensor, an acceleration sensor and the like, and a threat signal generator for generating a threat signal such as sound or light. , A key mechanism for operating these sensor mechanisms, and a monitor mechanism for displaying the operating status of the sensor mechanisms.

[0006]

FIG. 1 shows an embodiment in which a crime prevention / disaster prevention system according to the present invention is applied to a house. In the house, the room that require this crime and disaster prevention, providing a sensor mechanism S ₁ ~S _5. As shown in FIG. 2, the sensor mechanism S includes a human sensor 1, a thermal sensor 2, a gas / smoke sensor 3, and an acceleration sensor 4 for detecting an earthquake.
And a flash lamp 5 that emits flash light and a speaker 6 that emits sound. The flash lamp 5 and the speaker 6 constitute a threat signal generator of the present invention.

Further, in the sensor mechanism S, there are a warning lamp 7 for indicating that the user is currently in a guard state, a door closing lamp 8 for indicating that the door is locked, and an intruder when the apparatus is set in the guard state. Is provided. Note that reference numeral 10 in the figure denotes an emergency call device provided in the sensor mechanism S. This emergency caller 10
Outputs an emergency signal by pulling a triangular grip 12 fixed to a string 11 coming out of it. This emergency signal may be transmitted directly to an external emergency system, or may be transmitted to a predetermined room in a house. Reference numeral a denotes a modular unit for receiving a signal from a door-closing magnet switch attached to a window or a door. With the signal from this modular, the sensor mechanism S grasps the actual door-locking situation.

The above-described sensor mechanism S is shown in FIG.
As can be seen from the above, it is installed at about 50 cm from the floor 13. The reason why the sensor mechanism 2 is provided at a low position is to prevent the human sensor 1 from detecting a person other than a person, such as a dog or a cat, and issuing an alarm. Therefore, the installation height of the sensor mechanism S is slightly different depending on the environment of the house where the system is introduced. For example, in a home with large dogs,
It would have to be about 0cm high,
In a home without pets, you can set it at a very high position. However, the lower side of the line that divides the ceiling and floor into approximately two may be used as a rough guide.

In this regard, the conventional motion sensor is
They were set from the top of the room to the bottom, so that they could detect objects moving on the floor. For this reason, even when a pet or the like moves, it often senses the alarm and issues an alarm, and the present situation is that it is troubled by false alarms. However, if the sensor mechanism S is installed at a low position in the room as in this embodiment, even if the pet moves, it does not enter the sensing range, so that no alarm is issued. In addition, as shown in FIG. 3, the motion sensor 1 has a lower half covered with a shadow mask 14 so as not to detect a movement of a pet or the like below the installation height. In addition, the shadow mask 14 of the motion sensor 1 includes a fixed mask 14 a and a movable mask 14.
b, the sensing range of the movable mask 14b can be adjusted by moving the position of the movable mask 14b.

Further, each component constituting the sensor mechanism S is connected to a substrate b of the sensor mechanism S via a module. Therefore, if a cord (not shown) is connected to each of these components, each sensor can be placed at a free place away from the substrate b of the sensor mechanism S. For example, in an area where city gas having a low specific gravity is used, if the gas / smoke sensor is located at a lower position, a gas leak can be detected quickly. In any case,
As described above, components such as sensors are connected to the substrate b via the modular, so that the installation location of each component can be freely selected according to the environmental conditions.

The key mechanism K shown in FIG. 4 operates the sensor mechanism S. The key mechanism K includes a security set key 15, and when the security set key 15 is pressed, a security situation starts. At this time,
The alarm set lamp 16 lights up. When the warning set key 15 is pressed and the doors of each room are closed, the door closing lamp 17 is turned on. That is,
This system manages the opening / closing and locking information of the doors of each room, and can confirm the status.
Then, when the sensor mechanism S detects a person or smoke, the intrusion lamp 18 and the disaster prevention lamp 19 are turned on. Thus, to turn off the lamp once lit,
The key 20 must be used to enter a recite number.

The monitor mechanism M shown in FIG. 5 includes an alarm set key 21, an alarm set lamp 22, individual set keys 23 to 27 for setting an alarm for each room, and a set lamp 32 indicating the status of the individual set. Have. The monitor mechanism M includes a buzzer 33 and its buzzer 3.
An adjustment key 34 for adjusting the volume of the sound of No. 3 and a stop key 35 for stopping the sound of the buzzer are also provided. The monitor mechanism M can operate this system separately from the key mechanism K by pressing the alarm set key 21. Further, if any one of the individual set keys 23 to 27 is pressed after the alarm set key 21 is pressed, only the sensor mechanism S of the target room can be operated. Reference numerals 36 to 40 in the figure denote option set buttons used when a special function is added. Reference numerals 43 to 49 in FIG. 1 denote outlets for connecting the mechanisms S, K, and M to a power line.

The respective mechanisms are connected as follows. First, the sensor mechanism S is installed in all rooms that require crime prevention and disaster prevention. The key mechanism K is installed in a room that is easy to operate, such as a living room. Further, the monitor mechanism M is also installed in a room where people gather or a room of a person who is in a position to monitor the alert situation. For example, as a room where people gather, there is a living room, and as a room for monitoring the alert situation, a parent's bedroom or the like can be considered.
These mechanisms are connected using a power line communication system. Therefore, there is no need for special wiring for connecting these mechanisms, and this alone can significantly reduce construction costs. In the drawing, reference numeral 41 denotes a modem, and 42 denotes a distribution board.

Next, the operation of this embodiment will be described. By operating the key mechanism K, the alert status is set. At this time,
If each room is not locked, the
Does not light, the operator can recognize that the door is not closed. Then, it can be determined by looking at the monitor mechanism M which room is not closed. Then, when a person enters during the alert set, the human sensor 1 senses this, flashes the flash lamp 5, and emits a sound such as a dog voice from the speaker 6. At this time, the buzzer 3 of the monitor mechanism M
3 also operates, and the set lamps 28 to 32 blink to notify which room's sensor mechanism S is issuing an alarm.

Further, once the alarm function operates, the intrusion lamp 18 or the disaster prevention lamp 19 of the key mechanism K is turned on. The lamp 18 or 19 lit once in this way.
Does not turn off unless a recite number is entered with the 3 key 20. The reason for this is to make it possible to determine whether a person has invaded, for example, during absence, even after the fact. Further, as described above, in which room the sensor mechanism S operates can be determined by looking at the monitor mechanism M. Therefore, when the buzzer 33 of the monitor mechanism sounds, check the lamps 28 to 32,
It is possible to determine the room where a person has entered or has been in a disaster.

In the above description, a human intrusion has been mainly described as an example. However, in the case of a fire or an earthquake, an alarm or turning on a disaster prevention lamp is the same as in the case of a human intrusion. Almost the same. In addition, security and disaster prevention information,
As a matter of course, the data may be transmitted to an external security / disaster prevention system using a telephone line as shown in FIG.

[0017]

According to the first aspect of the present invention, crime prevention and disaster prevention can be integrated, so that it is not necessary to use a separate system for crime prevention and disaster prevention as in the prior art. Therefore, the system can be simplified and the cost can be significantly reduced. According to the second aspect, since the sensor mechanism, the key mechanism, and the monitor mechanism are connected using the power line communication system, no special wiring is required to adopt this system. As a result, construction costs can be significantly reduced.

According to the third aspect, since each sensor is connected to the sensor mechanism via the modular, each sensor can be set at an optimum location. According to the fourth invention, the sensor is installed in a range of 20 cm to 70 cm from the floor, while the lower side of the motion sensor is covered with a shadow mask, and the area to be covered is made variable by moving the shadow mask. Therefore, short pets are not mistaken for intruders.
