FIG. 2 is a configuration diagram of a smart key according to an embodiment of the present invention, and FIG. 3 is a diagram illustrating the smart key body of FIG. 2 in more detail.

Referring to FIG. 2, the smart key according to the embodiment of the present invention authenticates the smart card 30 and the smart card 30 in which the rights information of the user for driving the construction machine is embedded, And a smart key body 20 for extracting the user's authority information and setting the driving authority of the construction machine.

In this embodiment, the smart card 30 is an IC (Integrated Chip) card having an integrated circuit, and may be a contact card inserted into the insertion portion 21 of the smart key body 20 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 30 may be implemented in a wireless transmission (RF) system such as an RFID (Radio Frequency Identification). In this case, an electronic circuit module for recognizing an RF card may be implemented in the smart key body 20 have.

In this embodiment, it is assumed that a method of starting a construction machine using a smart key is a general key method, not a button method used in a smart key of a general passenger car. Construction machines, such as excavators and wheel loaders, generate a lot of vibration during operation, which increases the likelihood of malfunction in the case of a button system. Therefore, the operation stability of the construction machine can be improved by using the general key system.

3, the smart key body 20 according to the present embodiment includes a card input / output unit (I / O) 201, a power connection unit 203, a data communication unit 205, an authority setting unit 207, A display unit 209 and a reset unit 211. [

The card input / output unit 201 refers to a portion in which the smart card 30 is inserted in a contact or non-contact manner for the purpose of recognizing the smart card 30. The card input / output unit 201 may include a data input / output module for recognizing the smart card 30 in the form of an IC card and transmitting and receiving data.

The power connection unit 203 supplies power to the inserted smart card 30 to enable authentication of the smart card 30 and data communication with the smart key body 20. [ Various types of batteries may be built in the smart key body 20 for stable power supply. Here, the battery can be charged through wired charging or wireless charging. For example, when the smart card 30 is inserted into the smart key body 20, the battery can be charged in a non-contact wireless charging mode.

The data communication unit 205 transmits and receives data to and from the smart card 30, authenticates the inserted smart card 30, and extracts the user right information stored in the smart card 30. At this time, the data communication unit 205 can verify whether or not the inserted card is valid by exchanging a password with the smart card 30 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 207 sets the function of the construction machine that can be driven using the user right information of the smart card 30 extracted through the data communication unit 205. Here, the smart card 30 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 national or construction machinery manufacturer and may have control over all functions of the same type of construction machine manufactured by the same company. A general card is a privilege granted to the owner of a particular construction machine, and may have control over all functions of the construction machine. The management card is a privilege given to a construction machine manufacturer, a service company for after-sales service, a proprietor of a specific construction machine, etc., and can have only the control authority necessary for the maintenance of the construction machine. 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 20 It can be the driving key of the construction machine.

In this embodiment, the owner or the manufacturer manager of the construction machine can remotely set the authority of the smart key via the TMS communication unit 103. [ For example, in the case where the user's right is not granted as a result of authentication of the smart card through the data communication unit 205, or when the use time limit of the management card is required, the owner of the construction machine transmits the TMS And can arbitrarily grant authority to the function, time range, and the like of the construction machine that can be remotely driven by the smart card by communicating with the communication unit 103.

In this embodiment, the TMS communication unit 10 can store the usage history of the construction machine, that is, the time and function of the specific user using the construction machine, in the usage history DB 125 of the TMS server 12. In this way, by making each user's construction machine use history into a database, it becomes possible to easily utilize it for cause analysis when a problem occurs in a construction machine.

The function display unit 209 displays the function of the excavator which can be controlled by using the smart key according to the result of setting the smart key authority by the recognition or remote control of the smart card 20. [ The function display unit 209 may be implemented to display controllable function information on an LCD window outside the smart key body 20 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 reset unit 211 resets the functions of the smart key body 20 so that a single smart key body 20 can be shared by a plurality of users. For example, when the inserted smart card 30 is removed, all of the data communication unit 205, the authority setting unit 207, and the function display unit 209 can be initialized to a standby state. The smart card 30 can be exchanged with the smart card 30 by exchanging cryptographic keys with the TMS server 12 through the TMS communication unit 103, The security of the smart key can be further improved by performing the authentication process.

FIG. 4 is a diagram for explaining a process of setting a smart key authentication and a construction machine operation authority based on the system of FIG. 1. FIG.

Referring to FIGS. 1 to 4, an authentication procedure for confirming the validity of the smart card 30 inserted in the smart key body 20 is performed (S40). In this process, the authentication can be performed by exchanging the encryption key by the RSA encryption algorithm between the smart key body 20 and the smart card 30. At this time, if the card is not a valid card, it can be notified that the construction machine can not be driven through the function display unit 209 of the smart key body 20 or the like.

If the inserted smart card 30 is authenticated as valid, it is confirmed whether a user right for driving the construction machine is given (S41). Here, the user right of the smart card 20 can be set in various stages. For example, the user authority of the smart card 20 can be controlled by a master card having all the functions of all the excavators manufactured by the same company, A general card having authority, and a management card having only control authority necessary for maintenance of an excavator.

If the user right is granted, the user right information stored in the smart card 30 is extracted (S42). If the user right is not granted, the user right information is extracted through the control terminal 11 or the TMS server 12 Information is acquired (S43). The step S43 will be described in more detail with reference to FIG.

Then, in accordance with the obtained information, a construction machine driving authority of the smart key is set and a controllable function is displayed (S44). The function display displays controllable function information on the LCD window outside the smart key body (20), or each function is indicated by an LED light bulb. Functions with control permission are illuminated in green. Functions without control permission are displayed in red It can be displayed in various forms such as a light coming in.

Subsequently, the user can drive the construction machine according to the authority set in the smart key (S45).

5 is a diagram for explaining step S43 of FIG. 4 in more detail.

First, if the user authority is not granted to the smart card 30, the TMS communication unit 103 of the construction machine 10 requests the TMS server 12 for the user right information (S431).

Next, the TMS server 12 checks whether there is user right information stored in the function right DB 121 and the time right DB 123 in the server 12 using the authenticated user information through the smart card 30 (S433). If there is the stored information, it is transmitted to the TMS communication unit 103 (S435). The user rights information may be previously inputted through the control terminal 11 and stored.

If there is no user right information stored in the TMS server 12, the control terminal instructs the TMS server 12 to provide the user right information through the information request to the control terminal 12 (S437) May transmit the corresponding information to the TMS communication unit 103 of the construction machine 10 (S435) so that the authority of the smart key may be set. Alternatively, the control terminal 12 may directly communicate with the TMS communication unit 103 of the construction machine 10 to provide necessary user right information (S439).

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.
