Problems solved by technology

For digital control, time control is the simplest, but the time lag compensation cannot use the simplest time control. The reason for this paradox is also that the time is locked as the system clock

Abstract

The invention discloses a method for controlling the process parameter and the related data stream in real time, comprising the following steps: (1) establishing a distribution matrix for the multi-dimensional related data stream which comprises a multi-axis data stream and a parameter data stream by a PC system; (2) calculating a time value according to the multi-axis data stream and the feed speed by the PC system, adding the time value to the distribution matrix for the multi-dimensional related data stream, and formatting the distribution matrix for the multi-dimensional related data stream; (3) sending the formatted distribution matrix for the multi-dimensional related data stream to a programmable data stream controller by the PC system; (4) writing the time value into a speed timerand the multi-axis data stream and the parameter data stream into a data stream driver by the programmable data stream controller; and (5) controlling the data stream driver to send the multi-axis data stream and the parameter data stream to an executing mechanism by the programmable data stream controller at the given operation speed according to the set of the speed timer. The invention simplifies the real-time control of the related data stream as well as the real-time control and the acceleration-deceleration control of the process parameter.

Description

technical field [0001] The invention relates to the field of computer numerical control, in particular to a real-time control method of associated data flow of process parameters and a dynamic synchronization method of associated data flow. Background technique [0002] The so-called digitization is to discretize the analog quantity into a data flow of "0" and "1". A digital device is one that digitally processes an input data stream to produce the desired result. Thus, from the point of view of data flow, any digital device is a synthesis device of data flow. Digital TV synthesizes multi-dimensional data streams of video and audio into images and sounds that are consistent with each other. CNC machine tools synthesize multi-dimensional data streams of X, Y, and Z axes into motion trajectories, and so on. For multi-dimensional data streams, at each timing point, if the "0" and "1" information between data streams are interdependent, this coupling relationship is called tim...
