Abstract

A construction machine according to embodiments of the present disclosure may include a manipulation device configured to receive a command or data used to control an operation of a construction machine, an output device configured to generate at least one of visual information, auditory information, and tactile information related to the operation of the construction machine, a user login device configured to identify a user as a public user, a previous user, or a specific user according to a selected login method and set the construction machine based on the identified user, a processor configured to control at least one of the user login device, a storage device, a manipulation device, and an output device, and a storage device configured to store data used by the manipulation device, the output device, the user login device, and the processor.

Claims (29)

1 . A construction machine comprising:

a storage device configured to store data;

a manipulation device configured to receive a command or data used to control an operation of the construction machine;

an output device configured to generate at least one of visual information, auditory information, and tactile information related to the operation of the construction machine;

a user login device configured to identify a current user of the construction machine as any one of a public user, a previous user, or a specific user based on usage of a password and a time point at which a smart key is used and apply the identified current user's settings to the construction machine, wherein the specific user is a user logged in using the password and whose setting and operation information are stored in the storage device, the previous user is a last user that used the construction machine, and the public user is a user which is not the specific user or the previous user; and

a processor configured to control at least one of the user login device, the storage device, the manipulation device, and the output device,

wherein the user login device identifies the current user of the construction machine as the previous user when the same smart key as a previous user's smart key is recognized within a lock suspension time after the construction machine is turned off in a state in which a start lock function is activated.

2 . The construction machine of claim 1 , wherein the user login device identifies the current user of the construction machine as the public user when at least one smart key recognized within the lock suspension time after the construction machine is turned off in a state in which the start lock function is activated is not the previous user's smart key, or

when the at least one smart key is recognized after the lock suspension time is exceeded after the construction machine is turned off in the state in which the start lock function is activated.

3 . The construction machine of claim 1 , wherein the user login device identifies the current user of the construction machine as a public user when the at least one smart key is recognized in a state in which the start lock function is deactivated.

4 . The construction machine of claim 1 , wherein the user login device maintains the previous user's settings and operation information when the current user of the construction machine is identified as the previous user.

5 . The construction machine of claim 1 , wherein the user login device initializes the previous user's settings and the operation information when the current user of the construction machine is identified as the public user.

6 . The construction machine of claim 1 , wherein the user login device applies the specific user's settings and operation information that correspond to the password input by the specific user when the current user of the construction machine is identified as the specific user.

7 . A construction machine comprising:

at least one smart key interworking with the construction machine;

a start lock device configured to set a lock suspension time based on an input of a previous user of the construction machine; and

a user login device configured to:

identify a current user of the construction machine as any one of a public user, a previous user, or a specific user based on usage of a password and a time point at which the at least one smart key is used, and

apply the identified current user's settings to the construction machine,

wherein the specific user is a user logged in using the password and whose setting and operation information are stored in the storage device, the previous user is a last user that used the construction machine, and the public user is a user which is not the specific user or the previous user, and

wherein the user login device identifies the current user of the construction machine as the previous user when the same smart key as a previous user's smart key is recognized within the lock suspension time after the construction machine is turned off in a state in which a start lock function is activated.

8 . A user login method comprising:

identifying a current user of a construction machine as any one of a public user, a previous user, or a specific user based on usage of a password and a time point at which a smart key is used, wherein the specific user is a user logged in using the password and whose setting and operation information are stored in the storage device, the previous user is a last user that used the construction machine, and the public user is a user which is not the specific user or the previous user; and

setting the construction machine based on the identified current user,

wherein the identifying the current user of the construction machine includes identifying the current user of the construction machine as the previous user when the same smart key as a previous user's smart key is recognized within a lock suspension time after the construction machine is turned off in a state in which a start lock function is activated.

9 . The user login method of claim 8 , wherein the setting the construction machine includes setting the construction machine to maintain the previous user's settings and operation information when the current user of the construction machine is identified as the previous user.

10 . The user login method of claim 8 , wherein the identifying the current user of the construction machine includes identifying the current user of the construction machine as the public user when the at least one smart key is recognized in a state in which the start lock function is deactivated or a smart key different from the previous user's smart key is recognized in a state in which the start lock function is activated.

11 . The user login method of claim 10 , wherein the setting the construction machine includes setting the construction machine to initialize the previous user's settings and operation information when the current user of the construction machine is identified as the public user.

12 . The user login method of claim 8 , wherein the setting the construction machine includes setting the construction machine to change the settings and operation information of the construction machine into settings and operation information that correspond to the password input by the specific user when the current user of the construction machine is identified as the specific user.
