Remote control system and method for construction equipment

A remote control method of a construction machine for remotely controlling the construction machine including an operation device including a boom, an arm, and a bucket and an upper swing body in a remote area, the method comprising:

• receiving, by a remote device, a maximum distance to which a wrist is reachable in each direction axis of an anteroposterior direction X, a horizontal direction Y, and a longitudinal direction Z and setting a radius based on a distance smaller than the received maximum distance by a predetermined size as a workspace, and setting a predetermined area on an XY plane as an absolute swing area λ;
• tracking an operation angle βe of the bucket to track the operation angle βe of the bucket depending on a finger bending angle βh with respect to a palm of the operator and wirelessly transmit the tracked information to the construction machine;
• executing a position tracking mode to track a machine operating position E and wirelessly transmit the tracked information to the construction machine when a wrist position H of the operator belongs to the workspace;
• executing an absolute swing mode to recognize that a request for a swing operation is received from the operator and wirelessly transmit the swing operation request to the construction machine when the wrist position H of the operator belongs to the absolute swing area;
• executing an approximate position tracking mode to track the machine operating position E by setting a position H′ approximated to a point the closest to the workspace as the wrist position H of the operator and wirelessly transmit the tracked information to the construction machine when the wrist position H of the operator deviates from the workspace and the absolute swing area;
• and
• controlling, by the construction machine, driving of the operation device and the upper swing body in accordance with the tracking information or the swing operation request that is received from the remote device.

• tracking an operation angle βe of the bucket to track the operation angle βe of the bucket depending on a finger bending angle βh with respect to a palm of the operator and wirelessly transmit the tracked information to the construction machine;
• executing a position tracking mode to judge whether the upper swing body is driven when a wrist position H of the operator belongs to the workspace and only when the upper swing body is not driven, track a machine operating position E and wirelessly transmit the tracked information to the construction machine;
• executing an absolute swing mode to judge whether at least one of the boom and the arm is driven when the wrist position H of the operator belongs to the absolute swing area and only when the boom and the arm are not driven, wirelessly transmit a swing operation request to the construction machine;
• executing an approximate position tracking mode to judge whether the upper swing body is driven when the wrist position H of the operator deviates from the workspace and the absolute swing area and only when the upper swing body is not driven, set a position H′ approximated to the closest point to the workspace as the wrist position H of the operator and track the machine operating position E, and wirelessly transmit the tracked information to the construction machine;
• and
• controlling, by the construction machine, driving of the operation device and the upper swing body in accordance with the tracking information or the swing operation request that is received from the remote device.
