1. A construction equipment, comprising:
a lower traveling body;
an upper rotating body rotatably supported on the lower traveling body;
a work machine which comprises a boom, an arm, and a bucket operated a hydraulic cylinder, wherein the work machine is supported by the upper rotating body;
a control valve for controlling the hydraulic cylinder;
an operation lever for outputting an operation signal corresponding to an operation amount of a driver;
a work setting processing unit for setting a work area of the work machine;
a location information providing unit for providing at least one of location information and posture information of the work machine and location information of the work area; and
an electronic control unit for outputting a control signal for the control valve according to the signal inputted from at least one of the operation lever, the work setting processing unit, and the location information providing unit,
wherein the electronic control unit calculates an angle between the work area and the work machine, and controls a speed of the work machine based on the calculated angle,
wherein the electronic control unit controls the speed of the work machine based on an angle remaining to the work area of the work machine, wherein the angle remaining to the work area of the work machine is proportional to the speed of the work machine,
wherein the electronic control unit determines to be in a speed limit section when a difference between a current angle of the work machine for the work area and an angle of the work machine for the work area when the bucket invades the work area is less than or equal to a predetermined reference value.
