Remote control system and remote setting system for construction machinery

A remote setting system for a construction machine comprising a plurality of driven members including a plurality of vertically rotatable front members which constitute a multi-articulated front working device, a plurality of hydraulic actuators for driving respectively said plurality of driven members, a plurality of hydraulic control valves for controlling flow rates of a hydraulic fluid supplied to said plurality of hydraulic actuators, and front control means for controlling said plurality of hydraulic control valves and controlling operation of said front working device so as to form a preset target work plane, wherein:

• the system includes machine-side control means equipped in said construction machine and a remote control terminal,
• said remote control terminal comprises input means for inputting working data correlated to an external coordinate system that is set outside said construction machine and has a known position and posture;
• setting information converting means for creating setting information of the target work plane on the basis of the external coordinate system from the working data, and converting the created setting information into setting information of the target work plane on the basis of a machine body coordinate system (ΣSB) set on said construction machine;
• first wireless communicating means for transmitting the setting information of the target work plane on the basis of the machine body coordinate system (ΣSB) to said construction machine;
• and display means for displaying a positional relationship between said construction machine and the target work plane in correlation to the external coordinate system,
• said machine-side control means includes second wireless communicating means for receiving the setting information of the target work plane on the basis of the machine body coordinate system (ΣSB) from said remote control terminal, and
• said front control means controls said hydraulic control valves based on the setting information of the target work plane on the basis of the machine body coordinate system (ΣSB), thereby controlling the operation of said front working device so as to form the target work plane.
