| Abstract: | On the basis of analyses of drying machine with unwinding unit, a syn- chro control plan with MCS-51 single chip microcomputer is presented, its power drive adopts variable frequency and adjustable speed of AC motor. The algorithm of unwinding unit is given, the principle of synchro drive device controlled by single chip microcomputer and its realizations of software and hardware are introduced. The device can produce two synchro analogue signals to control both unwinding u- nit and constant speed unit, and can set up and regulate line speed of the machine on line, and can measure and display the length of cloth. The results of site run- ning show that the drying machine has strong synchronous ability, simple operation and reliability. |
