Application And Digital Re-design Of Double Closed Loop Direct Current Timing System Of TF-1350 Type Sugar Segregator

GuangXi is the main section of sugar production in our country Sugar segregator is thekey equipment of sugar that influence the qualit\ of sugar. Therefore. Scientific Council of GuangXl establish an important research subject [9810001 mark]that design TF-l35() type sugar segregator by Engineering College of GuangXi and Compressor Factors of LiuZhou and Optics and Machine Institute of ChuangChun.Timing system is the key part of TF-1350 type sugar segregator which is influenced by rapidity . stabilit\ and reliability . I analyse its theory and parts in detail.recorde and analyse questions in the job site. TF-l350 type sugar segregator timing system adopt double loop direct current timing system and PID adjustor which the whole s\stem is made up of simulation component. TF-1350 type sugar segregator timing system basicall\ meet demand of timing and sugar technics but esits some def,cicnc\ Such as. the method of control is not eas~ change because of simulation s\stem In addition.to those existins defects such as its numerous componcnts.lo~~ precision.lar~c sizc.high cost and liabilit~ etc.! put tèr~ard the project of digital double loop direct current timing system.Because I am familiar with 8031 singlechip. I use two pieces of 8031 siglechip module on hardware.One is used to double loop adjustor control and the other is used to SDR trigger control.The bus isolation technolog~ of double port RAM is adopted.ln the wa~ of software design. according to the demand of characteristic of svstcm.tirstl\,l'll) digital adjustor is used in Velocit\ loop and current loop. Then.according to character of timing .a single neuron l~l1) is used in ~elocitv loop. In the result of emluator.svstciii character irnpro\e.ln computer aided design.Matlah is used to the tool of emluator. We knox~ that double loop adjustor itnpro~e original timina svstcm.and inherit original merit ano realize reverse change.Because the progrom had been lasting. I onl\ attend installation and dehueeitie of [F-1350 type sugar scgregator.l summarize and find question in practice and complete the di~itial design task As soon as possible that I experience the ~~hole process from design to production of a large-scale scienti tic research item. Its impro\ cment to mc 1mm theor\ ~ practice afld have a great influence on my future oh.
