The control unit 5 transmits a drive signal for driving the predetermined smoke generating unit 4 to the smoke generating unit 4 so that the smoke generating unit 4 generates smoke. The number and positions of the moving object detecting means 31 and 32 used in the present invention are not particularly limited, but are at least one, and there is no blind spot in the guard area 1. Thus, it is possible to set an appropriate number and arrangement positions of the moving object detection means 31 and 32 so that a system capable of detecting an intruder can be taken.

The configuration of the moving object detecting means 31 and 32 themselves is not specified, and a conventionally known object detecting device constituted by using a medium such as an ultrasonic wave, an infrared ray, a laser, and a magnetic field line may be used. Is possible. Further, in the anti-theft device according to the present invention, the known anti-theft sensors 33, 34, 3 provided at the moving object detecting means 31, 32 and the entrance 8 or the windows 91 to 93, etc.
5, 36, etc., may be configured to operate in conjunction with the anti-theft detection sensor 3

May be configured to operate.

Furthermore, the smoke generating means 4 used in the present invention has no adverse effect on the human body in place of the conventional tear gas or odorous gas, and the bad odor is generated in the caution area 1. In addition, it is desirable that the smoke does not remain and that the smoke is quickly emitted and that the inside of the guard area 1 is filled with smoke, and that the smoke has a high concentration and that the intruder in the guard area has It is desirable to be able to completely obstruct the view, thereby making it impossible for the intruder to perform actions such as destroying or carrying objects to be watched in the watch area 1. .

The smoke-generating component used in the smoke-generating means according to the present invention is preferably one mainly composed of an alcohol component, and more specifically, one composed of a dihydric alcohol-based component. Things are desirable. Examples of fuming substances capable of efficiently producing smoke by suitable vaporization in the present invention include, for example, tripropylene glycol,
Propylene glycol, 1,3-butanediol, water and the like are appropriately mixed.

By using the above-mentioned fuming substance,
By elevating the temperature to about 200 ° C., it is possible to vaporize in a short time and generate the required concentration of smoke, and the fuming substance contains petroleum components such as kerosene and mineral substances. There is no unpleasant odor or pungent odor, so there is no adverse effect on the human body. Further, even when the temperature is lowered, there is no problem that the deposited impurities and the like of the component stay and spray harmful substances.

FIG. 2 schematically shows the structure of a specific example of the smoke generating means 4 used in the present invention. The liquid as the smoke generating substance is stored inside the main body 41 of the smoke generating means 4. At the same time as the storage section 42 is provided, the fuming substance sucked up from the storage section 42 is injected into a heating area 47 constituted by a suitable heating element 46 such as a ceramic heater, where vaporization and fume generation is performed. Will be

The heating element 46 is heated by a suitable heating means 48 such as electric heating. The vaporized and smoke-producing substance passes through the outlet from an appropriate nozzle 43 and is jetted into the security area. Preferably, a fan 44 or the like is provided at the upper and rear portions of the nozzle, and The portion is provided with a downward louver 45.

The louver 45 can be changed left and right and up and down. The smoke that is emitted is light and tends to rise immediately above the sky, but since the wind from the fan 44 blows downward through the louver 45, it immediately blows downward immediately after blowing. It is desirable to fill the guard area 1. FIG. 3 shows a schematic configuration of a cross-sectional view taken along the line AA of the smoke generating means 4 in FIG.

The nozzle 43 includes a heating element 46 and a heating means 48.
Together with the rotating base 41. Therefore, by rotating the rotary pedestal 41 right and left, the nozzle can be set at a desired position as needed. In addition, a rotatable front surface 40 having an air outlet is provided on the front surface of the nozzle 43 of the smoke generating means 4.

Therefore, after the position of the nozzle 43 is set, the front surface portion 40 is rotated so that the outlet is located at the front surface of the nozzle 43. In the present invention, when the moving object detection means 31 to 32 detects an intruder and outputs a smoke start signal via the control means 5 in response to the detection signal, the smoke generation component is immediately detected. It is required to emit smoke and fill the guard area 1 with the smoke. Therefore, it is necessary to cause the smoke component to emit smoke rapidly,
The heating body 46 of the smoke generating means 4 is activated, for example, when set to the alert state, or activated when the power is turned on,
It is desirable that the apparatus be so constructed that it is always preliminarily heated, and when the smoke start signal is output, the temperature is sequentially raised to a predetermined smoke allowable temperature to execute the smoke injection.

That is, in the smoke generating means 4 of the present invention, it is desirable that the heating element 46 be constantly heated to a predetermined temperature in order to rapidly heat the smoke generating component. Therefore, it is preferable that the heating element 46 has a predetermined temperature sensor, for example, a thermistor.

In the present invention, the smoke generating means 4 includes a plurality of moving object detecting means 31 to 31 provided in the security area 1.
The doorway 8 or the windows 91 to 93 outside the guard area 1 or in the area constituting the guard area
Is driven on the basis of a calculation result based on any of the information from the anti-theft sensors 33 to 35 provided in the computer or a combination thereof.

In the present invention, if the moving object detecting means 3 does not detect the presence of an intruder, the control means 5 sends a signal to stop the smoking operation to the smoking means 4.
The heating of the heating element 46 is
The smoke component is reduced to a temperature equal to or lower than the smoke temperature, thereby preventing the alcohol component, which is the smoke component, from evaporating, and the fan 44 is also stopped to prevent the smoke from being blown into the security area.

In the anti-theft device according to the present invention, when an intruder or the like is detected in the guard area 1,
The smoke generating means is driven to fill the inside of the security area with the smoke, and at the same time, the doorway, windows, etc. of the security area 1 are locked by an electronic lock or the like. It is desirable to configure so as not to enter. For this reason, for example, it is conceivable that smoke that is emitting may leak from the security area 1 and a third party may mistakenly determine that a fire has occurred. It is desirable to provide a smoke emitting means 7 for indicating that the smoke emitting means is emitting smoke.

On the other hand, an intruder who is confined in the security area 1 is deprived of freedom of action, and is thus worried about causing destructive behavior with excitement or fear. It is desirable to provide an appropriate smoke informing means 6 for informing that the smoke emitting means is emitting smoke inside the guard area, and to notify the intruder that the smoke emitting means is emitting smoke by voice information.

That is, both the smoke notification means 6 and the smoke display means 7 in the present invention use voice information or image information. Further, the smoke generating means in the present invention is linked to an alarm means provided anywhere inside or outside the guard area, and is connected to a central security center, a police station, or the like. It may be.

[0025]

The anti-theft device according to the present invention employs the above-mentioned technical configuration. Therefore, when the moving object detecting means detects a moving object in the caution area, the smoke emitting means is used. However, for the human body, a smoke-producing substance mainly composed of substantially harmless alcohol is vaporized by heating to generate smoke, and the inside of the guard area is filled with the smoke, thereby restricting the visibility of the intruder. Then, the intruder is rendered incapable of operating in the guard area, and finally the intruder can be arrested.

Further, since the front part having the nozzle and the air outlet is rotatable, the anti-theft device can be used even if it is installed at any place. Further, since the louver is set downward, the smoke does not immediately rise upward immediately after blowing, but instead blows downward, so that the smoke fills up from below to above in the alert area.
