Abstract

An activation system of a work machine includes a vehicle body control unit outputting a control signal to drive a vehicle body of the work machine with power supplied by a power source, and an authentication unit performing authentication of an operator of the work machine. The activation system of a work machine first activates the authentication unit, and activates the vehicle body control unit when the authentication unit authenticates that the operator boarding the work machine is a specific operator.

Claims (35)

1 . An activation system of a work machine comprising:

a computer including a processor that executes a processing according to a program,

wherein the computer is configured to:

perform communication with a terminal owned by an operator of the work machine;

determine whether or not the operator is a specific operator who has an operation right for the work machine, based on an operator ID received from the terminal;

display an operator ID selection screen on a monitor or a touch panel provided inside the work machine, in a case in which it is determined that the operator is the specific operator;

receive input of the operator ID by the operator via the monitor or the touch panel;

try to authenticate whether or not the operator is the specific operator based on the input operator ID; and

output a control signal to drive a vehicle body of the work machine with power supplied by a power source when it is authenticated that the operator is the specific operator.

2 . The activation system of a work machine according to claim 1 ,

wherein the computer is further configured to:

store setting data associated with a plurality of specific operators; and

output the control signal based on the setting data associated with the authenticated specific operator.

3 . The activation system of a work machine according to claim 1 ,

wherein the computer is configured to:

store proximity data in a storage unit of the computer in a case in which it is determined that the operator is the specific operator based on the operator ID received from the terminal; and

authenticate whether or not the operator is the specific operator based on the input operator ID and the proximity data.

4 . The activation system of a work machine according to claim 1 ,

wherein the computer is further configured to:

receive a selection of the operator ID by the operator via the monitor or the touch panel; and

authenticate that the operator is the specific operator when the selected operator ID indicates the operator who owns the terminal.

5 . The activation system of a work machine according to claim 4 ,

wherein the computer is further configured to:

store setting data associated with a plurality of specific operators; and

output the control signal based on the setting data associated with the authenticated specific operator.

6 . An activation method of a work machine comprising:

a step of performing communication with a terminal owned by an operator of the work machine;

a step of determining whether or not the operator is a specific operator who has an operation right for the work machine, based on an operator ID received from the terminal;

a step of displaying an operator ID selection screen on a monitor or a touch panel provided inside the work machine, in a case in which it is determined that the operator is the specific operator;

a step of receiving input of the operator ID by the operator via the monitor or the touch panel;

a step of trying to authenticate whether or not the operator is the specific operator based on the input operator ID; and

a step of outputting a control signal to drive a vehicle body of the work machine with power supplied by a power source, when it is authenticated that the operator is the specific operator.

7 . The activation method of a work machine to claim 6 , further comprising:

a step of receiving a selection of the operator ID by the operator via the monitor or the touch panel; and

a step of authenticating that the operator is the specific operator when the selected operator ID indicates the operator who owns the terminal.
