Description

Anti-theft system {Prevention of theft system}

The present invention relates to an anti-theft system, and more particularly, to an anti-theft system that detects an intrusion of an outsider and notifies an administrator of an intrusion situation while operating an alarm means.

In general, in order to protect the shops and houses from intruders, a detector or emergency bell is installed in the building to detect the intruder's intrusion and connected to the security company using a public telephone network or a separate wired communication network and managed by the security company. We are promoting safety by using

Accordingly, when an intruder is generated in a shopping mall or a house, the security company is notified of the intrusion situation through a public telephone network or a wired communication network, so that it is possible to quickly cope with the intrusion of outsiders and reduce the occurrence of various theft accidents.

However, the above anti-theft has a problem that is limited to the range of the area to be protected. For example, the items stored in the yard, crops such as rice, ginseng, and fruits grown in rice fields, fields, etc., because the range of the surveillance area is too wide, may cause intruders from all directions. There is.

As a result, a watcher resides in the open air and monitors objects or crops loaded in the open air so as not to be stolen, or fences around the monitoring area to prevent intruders from entering.

However, when a watcher resides and monitors goods or crops, there is a problem that the installation cost is high along with labor costs such as the need for a space for the facility together with a separate facility to be watched by the watcher. In addition, the installation of the fence not only takes a lot of facility costs, but even if the fence is installed, the installed fence is easily damaged, thereby limiting the intrusion of outsiders.

The present invention was devised to solve the above problems, the present invention detects the invasion of outsiders in a relatively large area of the monitoring area, such as ginseng field, paddy field, field or outdoor yard using laser light. It is an object of the present invention to provide an anti-theft system that can promptly respond to an intrusion by informing an administrator of an intrusion situation while operating an alarm means.

And another object is to provide an anti-theft system that can prevent malfunction due to wind or vibration.

It is also an object of the present invention to provide an anti-theft system that can be easily installed in a relatively large area.

In addition, the present invention has an object to provide an anti-theft system that can prevent theft accident by detecting the intrusion of outsiders even in an area where the electric facility is not.

In particular, since the refraction means for refracting the laser light is formed into a sphere, the irradiation path of the laser light can be set more simply through a simple operation.

That is, the reflector 72 constituting the refraction means can vary the irradiation path of the laser beam irradiated from the light emitting port 11 according to the fixed position of the circular ring 71 and the lifting and lowering of the lifting spiral shaft 721. Here, the circular ring 71 is rotated and moved back and forth along the outer circumferential surface of the laser emitter 1 and is positioned by the locking bolt 711, so that the reflector 72 is mounted on the front protrusion 712 of the circular ring. ) And the light emission opening 11 vary. And the reflector 72 refracts the laser beam irradiated from the light emitting port at a different angle in accordance with the lifting and lowering of the lifting spiral shaft 721 which is mounted to the tap hole of the front protrusion.

As the reflector mounted on the front projection of the circular ring changes its position through the locking bolt and the lifting spiral axis, the path of the laser beam irradiated from the light emitting part is varied, thereby expanding or reducing the range of the monitoring area. When changing the range of the region, the path of the laser light can be set more easily.

As described in detail above, the anti-theft system according to the present invention detects the intrusion of outsiders into the surveillance area by using a reflector to notify the administrator of the intrusion situation and the intrusion situation to the surroundings through an alarm means. Can respond quickly to intrusion situations.

In particular, by detecting whether the outsider invades the surveillance area through the reflector, for example, there is an advantage that can detect the outsider invades the relatively wide open area, such as a yard, paddy field, field.

In addition, by widening the width of the laser light irradiated from the light emitting port of the laser emitter through the lens means, it is possible to detect the light even when the laser light incident on the light receiving portion is out of the center of the light receiving portion, thereby preventing malfunctions caused by vibration or wind. Can be.

In addition, the path of the laser light irradiated from the laser emitter can be changed through the refraction means, so that the system can be more conveniently constructed.

Although the present invention has been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that many different and obvious modifications are possible without departing from the scope of the present invention from this description. Therefore, the scope of the present invention should be interpreted by the utility model registration claims described to include many such variations.
