Fig. 2 shows the smart key body of Fig. 1 in more detail; Fig.
3 is a diagram for explaining a process of setting an authentication and a user right of a smart key device for driving an excavator according to an embodiment of the present invention.

The above and other objects, features, and advantages of the present invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawings, which are not intended to limit the scope of the present invention. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a configuration diagram of a smart key device for driving an excavator according to an embodiment of the present invention, and FIG. 2 is a detailed view of the smart key main body of FIG.

Referring to FIG. 1, a smart key device for driving an excavator according to an embodiment of the present invention authenticates a smart card 20 and a smart card 20 in which user's right information for driving an excavator is embedded And a smart key body 10 for reading out the user's authority information from the smart card 20 and setting the driving authority of the excavator.

In this embodiment, the smart card 20 is an IC (Integrated Chip) card having an integrated circuit, and may be a contact card inserted into the insertion portion 11 of the smart key body 10 or a non- have. When an IC card is used as a contact type card, much more data can be stored than in a conventional magnetic card, various applications can be driven, and hacking becomes very difficult, thereby greatly improving security.

The smart card 20 may also be implemented in a wireless transmission (RF) manner such as an RFID (Radio Frequency Identification). In this case, an electronic circuit module for recognizing the RF card may be implemented in the smart key body 10.

In the present embodiment, it is assumed that the method of starting up the excavator using the smart key body 10 is a general key method rather than a button method used in a smart key of a general passenger car. Since the excavator generates a lot of vibration during operation, there is a high possibility that malfunction occurs in the case of the button type. Therefore, in order to increase the stability of the excavator, a general key system can be used instead of the button system.

2, the smart key body 10 according to the present embodiment includes a card input / output unit (I / O) 101, a power connection unit 103, a data communication unit 105, an authority setting unit 107, A key duplication unit 111, and a reset unit 113. The display unit 109, the key duplication unit 111,

The card input / output unit 101 refers to a portion where the smart card 20 is inserted in a contact or non-contact manner for recognizing the smart card 20. The card input / output unit 101 may include a data input / output module for recognizing the smart card 20 in the form of an IC card and transmitting and receiving data.

The power connection unit 103 supplies power to the inserted smart card 20 to enable authentication of the smart card 20 and data communication with the smart key body 10. Various types of batteries may be built in the smart key body 10 for stable power supply.

The battery can be charged through a wired charging or a wireless charging method. For example, when the smart card 20 is inserted into the smart key body 10, it means that the battery can be charged in a non-contact wireless charging mode. The data communication unit 105 transmits and receives data to and from the smart card 20 Authenticates the inserted smart card 20 and reads the user right information stored in the smart card 20. [ At this time, the data communication unit 105 can verify whether or not the inserted card is valid by exchanging a password with the smart card 20 using a public key authentication method using an RSA (Rivest Shamir Adleman) encryption algorithm . Since the RSA encryption algorithm is well known in the technical field of the present invention, a detailed description thereof will be omitted.

The authority setting unit 107 sets the function of the excavator that can be driven using the user right information of the smart card 20 read through the data communication unit 105. Here, the smart card 20 can be classified into a master card, a general card, and a management card according to a set user authority. MasterCard is the authority granted to a country or excavator manufacturer, and can have control over all the functions of all excavators manufactured by the same company. A generic card is a privilege given to the owner of a particular excavator, and can have control over all functions of that excavator. The management card is a privilege given to the excavator maker, the service company for the after sales service, the owner of the specific excavator, etc., and can have only the control authority necessary for the maintenance of the excavator. The smart key device according to the present invention may have different control rights depending on which smart card 20 is inserted in the same smart key body 10 It can be a driving key of an excavator.

The function display unit 109 displays the function of the excavator which can be controlled by using the smart key according to the recognition result of the smart card 20 and the authority setting result. The function display unit 109 may be implemented to display controllable function information in an LCD window outside the smart key body 10 or each function may be displayed as an LED light bulb, Functions without control authority can be implemented in various forms that can efficiently inform the user of the smart key, such as a red light.

The key duplicating unit 111 performs a function of granting a certain range of user authority to a new smart card that is not authorized according to the authority set by the smart card 20. [ However, it is preferable that the grant of the new privilege is realized only by the master card, or that the new privilege can be granted in stages according to the privilege of the existing smart card 20. [ For example, when a master card is used, authorization of a general card and a management card can be granted, and when a general card is used, authorization of a management card can be implemented.

The reset unit 113 resets the functions of the smart key body 10 so that one smart key body 10 can be shared by using a plurality of smart cards. For example, when the inserted smart card 20 is removed, all of the data communication unit 105, the authority setting unit 107, and the function display unit 109 can be initialized to a standby state. Also, the security of the smart key can be further improved by performing a re-authentication process by exchanging a password with the smart card 20 at predetermined intervals even while the smart card 20 is inserted.

FIG. 3 is a diagram for explaining a process of setting a user right and authentication of a smart key device for driving an excavator according to an embodiment of the present invention. Referring to FIG.

First, when the smart card 20 is inserted into the smart key body 10, an authentication procedure for confirming whether the inserted smart card 20 is a valid card is performed (S301, S303). In this process, authentication can be performed by exchanging the encryption key by the RSA encryption algorithm between the smart key body 10 and the smart card 20.

If it is determined that the card is valid as a result of the authentication, the rights information of the user stored in the smart card 20 is read (S305). The user authority of the smart card 20 can be set in various stages. For example, a master card having control authority for all functions of all excavators manufactured by the same company, a general card having control authority for all functions of a specific excavator, a management card having only control authority necessary for maintenance of an excavator, etc. This can be. Accordingly, the drive key of the excavator having different control rights can be obtained according to which smart card 20 is inserted into the same smart key body 10.

Then, the user authority of the smart key is set according to the read information and a controllable function is displayed (S307). The function display displays controllable function information on the LCD window outside the smart key body (10), or each function is displayed as an LED bulb, the functions for which the control authority is green light, It can be displayed in various forms such as a light coming in. If it is determined in step S303 that the smart card is not a valid smart card, the LED is turned on to indicate that the excavator is not authorized to operate (S309).

The foregoing description is merely illustrative of the present invention, and various modifications may be made by those skilled in the art without departing from the spirit of the present invention. Accordingly, the embodiments disclosed in the specification of the present invention are not intended to limit the present invention. The scope of the present invention should be construed according to the following claims, and all the techniques within the scope of equivalents should be construed as being included in the scope of the present invention.
