Speed control method for increment-type encoder of cold rolling pickling processing production line

Abstract

The invention relates to a speed control method for an increment-type encoder of a cold rolling pickling processing production line and belongs to the technical field of cold rolling pickling processing production lines. The technical scheme comprises steps of adding an increment-type encoder speed control function block to a cold rolling pickling processing production line control system; inputting the hardware address of the increment-type encoder, and the relative reduction ratio and the roller diameter of a roller where the absolute value code is located required for the increment-type encoder speed control function block; and the increment-type encoder speed control function block directly outputting the rotation direction of the roller in which the increment-type encoder is located, the state of the increment-type encoder, and the linear velocity generated by the rotation of the roller where the increment-type encoder is located. The beneficial effects are that the measurement precision of the increment-type encoder can be ensured and the error caused by the artificial data processing factor can be eliminated. At the same time, the method is easy to use and can be easily transplanted. The desired speed or distance can be obtained only by inputting the address of the increment-type encoder, the roller diameter and the reduction ratio of the roller.

Description

technical field [0001] The invention relates to a method for controlling the speed of an incremental encoder in a cold rolling pickling production line, and belongs to the technical field of cold rolling pickling production line control. Background technique [0002] In the cold-rolled pickling production line, an incremental encoder is often installed on a fixed roll to measure the speed of the strip and calculate the position of the strip. Usually, the counter module is used in the primary control system Signal collection is performed on it, and the collected signal is a range of -2 31 -(2 31 -1) is a 32-bit binary value. This value is very difficult to handle in the system, and it is easy to cause calculation errors and affect the control accuracy. At the same time, the programming is very complicated. Contents of the invention [0003] The purpose of the present invention is to provide a speed control method of an incremental encoder in a cold-rolled pickling product...
