Abstract:
A target excavating-surface setting system for an excavating machine, in which a target excavating surface (T) is set parallel to an external reference (R) installed outside a machine body (1B) and a front device (1A) is controlled for said target excavating surface, thereby carrying out excavation continuously along said target excavating surface, wherein said system comprises:input means (7) for setting said target excavating surface (T); detecting means (8a,8b) for detecting status variables relating to a position and a posture of said front device (1A); first computing means (11b,11c; 11b,11s,11t) for computing positional relationships among said body (1B), said external reference (R) and said target excavating surface (T) by using signals from said input means and said detecting means; and second computing means (11e-11h,11j) for executing picture processing by using the positional relationships computed by said first computing means, and producing and outputting picture signals to display the positional relationships among said body, said external reference and said target excavating surface.
