Title:
COMMAND VALUE GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/042704
Kind Code:
A1
Abstract:
Provided is a command value generating device (100), comprising: a segmenting unit (110) which segments a work program (10) into a plurality of execution units and generates segmented work programs; a parallel computing unit (120), further comprising a plurality of computing devices, which executes the segmented work programs in parallel for each of the execution units and generates, for each of the execution units, a segment command which is a group of interpolation points upon an implement path; and a command value generating unit (130) which generates an implement movement command (11) from the segment commands for each of the execution units. In at least one of the segmented work programs before or after a segmenting point, the segmenting unit (110): computes an acceleration distance which is traveled to reach a command speed on the basis of a preset acceleration with respect to an ending portion of one of the segmented work programs prior to the segmenting point and a start portion of one of the segmented work programs after the segmenting point; computes such that a degree of overlap in the segmenting point of the segmented work programs is greater than or equal to the acceleration distance; and causes the start and end portions of the segmented work programs to mutually overlap by the degree of overlap.
