BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing theft of construction equipment,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an anti-theft device for a construction equipment, It is possible to set the state on (On), so that the theft prevention terminal which periodically transmits alert notification and GPS position information to the outside when the attachment is stolen is built in, whereby the position of the stolen object can be quickly tracked, The present invention relates to an improved anti-theft device for measuring and recording actual working time of an attachment.

As shown in Fig. 1, for example, an excavator used in construction is generally constructed such that an upper revolving structure 2 is pivotally mounted on a crawler type lower traveling structure 1, And a front work mechanism 4 and the like are provided together with a cab 3 for operation. The front working mechanism 4 includes a boom 5 provided on the upper swing body 2 so as to be capable of lowering and raising operations and an arm 6 And a front attachment is detachably mounted on the distal end of the arm 6. [

Typical of these front attachments are buckets, which are suitable for excavating soil. There are various front attachments other than the buckets, and an optimum front attachment is attached to the arm 6 in accordance with the type of work to be performed.

Such an excavator is attached to the tip of the arm 6 as a front attachment of a hydraulic excavator, in order to crush the crushed material such as a large rock or a concrete lump. The breaker 7 is structured such that a chisel 7a made of a steel bar or the like having a sharp end is mounted and driven by a breaker cylinder (not shown).

Therefore, by supplying the hydraulic pressure from the hydraulic pump to the breaker cylinder of the breaker 7, the chisel 7a is reciprocally operated to crush it by striking the crushed material.

Such a frequency transfer measurement test vibrates a jig (not shown) provided with the attachment anti-theft device 100 according to the present invention, and measures the impact force and the vibration response to a frequency band up to 1000 Hz Measurement, and analysis.

As can be seen from the results of the measurement test, the jig provided with the attachment anti-theft device 100 according to the present invention has the jig having the frequency band of 200 to 500 Hz among the vibrations transmitted from the outside to the internal circuit board of the anti- It has proven to effectively block vibration.

Meanwhile, the attachment anti-theft device 100 according to the present invention sets the alarm state to on when the attachment operation is completed and the worker leaves the site by remote control of the anti-theft terminal 110.

In the case where the alarm state is ON, when the brake 7 is stolen, the motion is detected by the acceleration sensor 112 built in the anti-theft terminal 110, and when the anti-theft terminal 110 is stolen .

Accordingly, the anti-theft terminal 110 generates a warning sound through the buzzer 120, transmits the management position information to the server (not shown) through the GPS module 116 and the CDMA module 118, The movement position and path of the attachment 7 are displayed.

FIG. 8 shows various types of information transmitted to the server in real time by the anti-theft terminal 110 and stored in the server.

For example, as shown in FIG. 8A, various useful message information 192 such as the stolen state, the security state, the battery charging state, and the time state is displayed on the screen of the server.
