Characterized in that the secret code input key pad 11 to further receive.

Referring to the effect of the anti-theft device of the construction machine of the present invention configured as described above are as follows.

First, the construction machine anti-theft device of the present invention includes an antenna 2, an authentication determination unit 3, an authentication display unit 4, and a control unit 5 installed in the equipment including a driver RFID tag 1 largely. What is done is the main technical component.

At this time, the driver portable RFID tag (1) is equipped with an antenna, a transceiver, a transponder (not shown) on the smart card type card for easy portability, and the unique authentication number (identifier) of the equipment is recorded through a separate authentication procedure. As such, the information such as the unique authentication number (identifier) is transmitted wirelessly through the antenna.

As described above, since the RFID tag 1 can record a unique authentication number (identifier) for the corresponding equipment (that is, the READ function is provided), if the RFID tag 1 is lost, The authentication code and code can be stored in the new RFID tag issued through the authentication procedure.

In addition, the antenna 2 is installed in the equipment and when the RFID tag 1 is within a set distance (that is, at a distance that can transmit the transmission energy for various signals transmitted from the RFID tag 1) When the RFID tag (1) is transmitted to the authentication determination unit 3 by receiving the identification number signal, etc. unique to the equipment in real time in real time, the authentication determination unit 3 is similar to the antenna (2) Decode the authentication number received through the antenna (2) installed in the equipment and compares the authentication number stored in itself to determine the validity of the received authentication number and then the result of the authentication display unit 4 and the control unit ( 5).

In addition, the authentication display unit 4 is installed on the equipment to display whether or not the authentication according to the result determined by the authentication determination unit 3 to the owner, the authentication display unit 4 such that the authentication whether the owner through the time It may be configured as a display that displays a letter to recognize, or may be configured as a voice signal output unit for outputting a voice signal to recognize whether or not authentication through hearing.

Then, the control unit 5 receives the authentication result signal output from the authentication determination unit 3 and performs the anti-theft function to lock the engine or shut off the fuel line if it is not the authorized authentication number as a result. In the case of the authentication number, the anti-theft function is released to enable the normal operation of the equipment.

At this time, the authentication determination unit 3 and the authentication display unit 4 is preferably installed on the instrument panel 20 in the equipment so that the owner can easily see.

On the other hand, the owner of the equipment may also be lost while carrying the RFID tag (1), so in this case, after receiving a new RFID tag after a separate authentication procedure, the equipment equipped with the authentication number recorded on the new RFID tag You will need to authenticate yourself by typing in.

In the present invention, when the equipment owner loses the RFID tag 1 by installing the secret code input keypad 11 on the instrument panel 20, the new RFID tag is supplied through a separate authentication procedure as described above. After the authentication number recorded in the corresponding new RFID tag is directly input through the secret code input key pad 11 in the device to be authenticated, then the new RFID tag can be used to perform an anti-theft release function of the device.

Therefore, the device can be unlocked by the password frequency of the RFID tag carried by the driver, so it can be started without cumbersome authentication procedures.If the owner of the equipment loses the RFID tag, the new RFID tag goes through a separate authentication procedure. When the tag is supplied, the owner can enter the desired certification number directly on the device to be authenticated.

In addition, another embodiment of the present invention is that the microphone 6, the A / D converter 7, the sound source comparator 8, the alarm 10 and the alarm driver 9 are additionally provided in the above-described technical configuration. It is a technical component.

At this time, the microphone 6 is installed in the equipment and converts the impact sound or the bursting sound of the glass from the outside into an electrical signal to transmit to the A / D converter (7), the A / D converter (7) It is transmitted to the sound source comparator 8 for converting the detected sound source output as an analog signal through the microphone 6 to a digital signal.

In addition, the sound source comparator 8 compares the frequency and level magnitude of the detected sound source input as a digital signal from the A / D converter 7 with a preset reference value and compares the result with the control unit 5 and the alarm driver ( Will be displayed as 9).

At this time, the sound source comparator 8 stores information on the sound source level, frequency range, etc. of the impact sound and the broken sound by external intrusion. This is compared with the normal external noise and judged. For example, the pre-set glass burst sound stores numerous patterns of impact sound generated when the glass is broken, and is equipped with a high-performance digital signal processor (DSP) and memory and noise of other impact sounds. Input to the pattern is also possible.

When the driving signal is generated in the sound source comparator 8 because the impact sound or the bursting sound detected by the impact from the outside is detected by the sound source comparator 8 or more than a predetermined level, the alarm driver 9 is a buzzer or an alarm lamp. The configured alarm 10 is driven to allow the owner of the equipment to know that there is an intruder in the equipment through hearing or vision.

In addition, the controller 5 receiving the intruder detection signal from the sound source comparator 8 because the impact sound or the bursting sound detected by the impact from the outside as determined by the sound source comparator 8 is equal to or greater than a predetermined level as described above. By outputting the "off" signal to various valves of the switch or fuel line, even if an intruder enters the equipment, the engine will not be started even if the intruder enters the equipment, thus preventing theft of the equipment completely.

At this time, the A / D converter 7 and the sound source comparator 8 and the alarm driver 9 may be installed in the equipment, but in this case, the electronic equipment installation part of the equipment has to be dismantled and installed. It is preferable to install and use these in the hands-free 30 which are made.

In this way, when the A / D converter 7, the sound source comparator 8 and the alarm driver 9 are installed in the hands free 30, the equipment is hands free when the device is KEY OFF (but the master switch is ON). The sound source comparator 8 inside the device enters the sensing mode.

Therefore, even when the locking function is not set due to a construction site request or a driver's mistake, the alarm 10 may be activated by sensing the glass rupture sound due to external intrusion through the microphone 6 as well as the automatic locking mode. The anti-theft function can be added using the hands-free system 30 installed on the construction machine without any additional device in constructing the anti-theft system of the equipment. In addition to improving customer satisfaction due to prevention, the security of equipment can be greatly improved.

The operation state of the apparatus of the present invention having such a configuration will be described below with reference to the flowchart of FIG. 3.

First, when the key of the equipment is "on", power (B +, IG) is supplied to the instrument panel 20, and the authentication determination unit 3 receives the AC power and the external authentication signal request signal through the internal antenna 2 from the RFID tag (1). ) And ready to receive RFID signal.

In this state, the RFID tag 1 enters the reception area and the RFID tag 1 transmits an authentication signal to the AC power received from the antenna 2, wherein the authentication determination unit 3 receives the signal. Received will be compared with each other and stored in the authentication number stored in itself.

As a result, when a non-normal authentication signal is input, the authentication determination unit 3 transmits the result to the authentication display unit 4 and the control unit 5, so that the control unit 5 displays the result on the authentication display unit 4 to the driver. Ensures that the machine remains locked.

However, when the authentication number received from the RFID tag 1 is a result of the determination made by the authentication determination unit 3 is an authorized authentication signal 1 (which means "the authentication number of the RFID tag"), the control unit 5 In the display panel, the authentication display unit 4 of the instrument panel 20 indicates a normal authentication state, and an actuator such as an engine start relay or fuel valve line opening is operated. In this case, the authentication display unit 4 of the instrument panel 20 is normal. It shows the status that the driver is verified by sound or lamp.

Meanwhile, the anti-theft device further includes the microphone 6, the A / D converter 7, the sound source comparator 8, the alarm 10, and the alarm driver 9 in the above-described technical configuration, or the RFID tag. If the microphone 6 and the A / D converter 7, the sound source comparator 8, the alarm 10, the alarm driver 9 and the controller 5 are not provided, the driver does not set the lock function. In one state, when the operation is terminated in the "KEY OFF" state, the sound source comparator 8 in the hands-free 30 receives a signal output from the A / D converter 7 and enters into a sensing mode state.

At this time, the sound source comparator 8 stores information of the patterns of the impact sound or the burst sound in advance in order to distinguish the external noise input from the external noise and the impact force or the glass burst sound for theft.

As such, when the intrusion indication that a predetermined output signal is generated in the A / D converter 7 is detected while the sound source comparator 8 enters the monitoring mode, the sound source comparator 8 stores the frequency and level stored therein. It compares the information of the sound source and the input noise of the to determine whether the lock setting.

When the sound source comparator 8 determines that there is an intruder, the result is transmitted to the control unit 5 so that the control unit 5 performs an engine locking function, which is an anti-theft function, and the instrument panel 20. By driving the alarm 10 is installed to generate an alarm sound or to operate a flashing alarm light.

The anti-theft function (that is, the function of turning off the start switch or the fuel valve line and the device entering the locked state) performed by detecting the presence of an intruder is the authorization signal 2 (this is the manual input key input by the operator) It will continue until it is entered).

It should be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
