Operational stability enhancing device for construction machinery

Abstract

Provided is an operational stability enhancing device for construction machinery. The operational stability enhancing device for construction machinery according to the present invention comprises: a plurality of cameras that capture images of the vicinity of a construction machine; a plurality of sensors that detect an obstacle located in the vicinity of the construction machine; a monitor that displays the images of the vicinity of the construction machine captured by the plurality of cameras; an electronic hydraulic control valve that controls the output flow rate of the driving unit of the hydraulic system so as to correspond to the operation signal from the user operation unit of the construction machine; and a control unit that displays the captured image of a detected object on the monitor through screen conversion or changes the image for the user to easily recognize the image when the detected object approaches the construction machine in the case where the detected object is detected by the sensor as being in the vicinity of the moving path and where the detected object is a target to avoid.

Description

technical field [0001] The present invention relates to an operation safety improving device of a construction machine. Background technique [0002] Generally, a construction machine such as an excavator is configured such that an upper revolving body can freely rotate on an undercarriage. In this way, when the construction machine is operating, the upper revolving body may rotate relative to the lower traveling body or the lower traveling body may retreat. In this case, there is a blind spot where the operator operating the construction machine cannot visually confirm the . [0003] In contrast, the operator needs to operate the construction machine while looking at a mirror installed on the upper revolving body of the construction machine or directly confirming the corresponding movement path with the naked eye, and thus there is a problem that work efficiency is reduced. [0004] Therefore, in order to solve the above-mentioned problems, an operation safety improvement...

Problems solved by technology

[0006] However, in the screen display device of a construction machine to which the above-mentioned conventional AVM system is applied, since the camera is provided only in front of the cab of the construction machine, that is, on the left front side of the construction machine, it cannot accurately recognize the The blind area covered by booms or buckets, that is, the position information of obstacles such as wires and utility poles on the upper right side of the construction machine, so that when lifting the boom or rotating the boom to the right The problem of safety incidents

[0007] In addition, the above-mentioned conventional construction machine operation safety improvement device only simply displays the image on the moving path of the construction machine, so there is a problem that the operator needs to check the monitors one by one. The distance between obstacles confirmed by the operator through the monitor depends on the feeling, so there is a problem of safety accidents when the distance information to the obstacle cannot be correctly recognized.
