Patent ID: 8195344

Claim:
A remote control system of a construction machine, comprising: a remote device including a plurality of sensors for sensing a finger bending angle β h with respect to a palm of an operator and a wrist position H of the operator, a remote control unit tracking an operation angle β e of a bucket depending on the finger bending angle β h with respect to the palm of the operator and a machine operating position E depending on the wrist position H of the operator, and a remote wireless transmitting and receiving unit wirelessly transmitting the tracked operation angle β e of the bucket or the machine operating position E to the construction machine; and a construction machine including an operation device including a boom, an arm, and a bucket, and an upper swing body, and controlling driving of the upper swing body or the operation device depending on the operation angle β e of the bucket or the machine operating position E received from the remote device, wherein the remote device generates an absolute coordinate system using a rotational center point of an arm of the operator as an original point for setting a workspace, sets a predetermined angle in a Y-axis direction on the basis of an X axis in an area within a radius smaller than an inputted maximum radius by a predetermined size on an XY plane as the workspace when a maximum distance to which a wrist reaches in each direction axis of an anteroposterior direction X, a horizontal direction Y, and a longitudinal direction Z is inputted, and thereafter, matches a remote coordinate system and a machine coordinate system depending on the set workspace each other.
