The present invention relates to an engine idling control device of an excavator and a method thereof, wherein the invention comprises: a first signal detecting unit; a second signal detecting unit; and an engine idling control unit which automatically stops or drives the engine according to a state of the engine, an on and off state of a function selecting switch detected by said first signal detecting unit, and an operated state of a safety device detected by said second signal detecting unit. Since the engine is automatically stopped or driven according to the state of the engine, the on and off state of the function selecting switch, and the operated state of the safety device in which a user's desire to work can be known since the user's desire to work is maximally reflected therein and which has convenience, fuel use and carbon dioxide generation can be reduced, and in addition, a stop & start function of the engine can be easily implemented according to the user's selection.
Description
technical field [0001] The invention relates to an engine idling control device for an excavator and a method thereof. More particularly, the present invention relates to an engine idling control device for an excavator and a method thereof, which can recognize the state of the engine, the on / off state of a function option switch, and the user's work that has been reflected to the maximum extent. It is intended to reduce fuel usage and carbon dioxide generation by automatically stopping or driving the engine according to the operating state of the safety device with convenience, and to easily implement the stop and start function of the engine according to the user's selection. Background technique [0002] In general, excavators have a function that prevents unnecessary fuel consumption by reducing the number of revolutions of the engine to a minimum number of revolutions (idle state) if no operation is input when the engine is driven for a predetermined period of time. co...
