Method of double handle screening control for walking speed of engineering machinery

The present invention discloses a method of masking control engineering double handle mechanical walking speed, the first counter coupled to the controller using a program for internal timing angular velocity potential and the two self-resetting of the adjustment handle, a timing of every predetermined time ΔT two resetting a value of the angular displacement of the handle from the a / D conversion, and a value obtained through a / D conversion judgment, if it is determined that one of the adjustment handle is displaced, i.e. the adjustment handle lock shield and a further adjustment handle, Engineering traveling speed mechanical control of an adjustment handle, i.e. by displacing; further use within the controller programmed with a handle value of the angular displacement of the dead zone, when the controller reads the angular displacement of the adjustment handle in damn region, i.e. determination the behavior of the handle is not operated. The present invention is a simple, reliable, good safety and stability, and is capable of optimizing the layout of the console, can be converted construction machine control console walking speed in the non-stop state of the double handle mask control method.
