A pulse processing generation method and device

Abstract

The invention discloses a pulse processing generation method and device. The influence of original and unstable errors is reduced to a degree enough to be ignored through enough large process gain, sothat the minimum mastering precision of the distance and the speed in industrial production or motor control is reduced to the minimum, stepless adjustment and theoretical limitation-free frequency division is achieved, and a higher-precision control effect is achieved.

Description

technical field [0001] The present invention relates to the technical field of pulse processing, in particular to a method and device for generating pulse processing. Background technique [0002] Pulse signal is a periodic discrete electrical signal, and its discrete characteristics and periodic performance are presented on the time axis in various forms. Modern electronics, industry, aerospace, and almost all technologies related to electricity and control have it. The most typical one should be a square wave signal. In each chip, the square wave signal exists as a heartbeat. [0003] In the control, the periodic characteristic of the pulse signal is the most obvious and important. Usually, to change the period of the pulse signal, a phase-locked loop (PLL) is a commonly used hardware technical means, but most of the phase-locked loops (PLL) in the control chip are hardware that has been solidified in the chip and cannot be used and changed. What can be changed and used ...

[0005] But it is not difficult to see that the only formula of this scheme, formula The final value of N is the integer part of the result on the right. In the case of low-frequency pulse input, the error caused by the deviation of a few tenths will be amplified due to the reduction of the base (deviation / N ); such as: in the printing production operation, the transmission device mostly relies on the encoder signal as an important basis for actually triggering printing. The pulse signal period P) is 1000, the frequency division number D is 7, and the frequency multiplication number M is 13 (the output pulse period should be 0.54 times the input pulse period), then after calculation, N=538.46..., the deviation of which is only 0.46 It accounts for 0.085% of the final output result; and if the production machine just speeds up or runs at a low speed, the situation will be different. At this time, P is 20, the frequency division number D is 7, and the frequency multiplication number M is 13. After calculation, N =10.76..., at this time, the deviation of 0.76 accounts for 7.6% of the final output result, which confirms the previous statement that the error is amplified; at the same time, this method also restricts the selection of frequency division and multiplication
