摘    要

 我國(guó)滾塑機(jī)的開發(fā)研究可追溯到60年代，但真正大規(guī)模工業(yè)化生產(chǎn)，還是在80年代中、后期，從國(guó)外引入先進(jìn)滾塑設(shè)備與技術(shù)之后。決大多數(shù)廠家設(shè)備仍以進(jìn)口為主。所以對(duì)于滾塑機(jī)的設(shè)計(jì)研制極具社會(huì)意義。
 本設(shè)計(jì)系統(tǒng)，以單片機(jī)（8031）作為轉(zhuǎn)臺(tái)檢測(cè)和控制核心。采用變頻調(diào)速器作為電機(jī)的調(diào)速控制設(shè)備，接受單片的D/A輸出量作為變頻器的給定值，按照給定值工作。位置檢測(cè)采用電渦流式位置傳感器。單片機(jī)控制電路主要由一片8031及程序存儲(chǔ)器與數(shù)據(jù)存儲(chǔ)器的擴(kuò)展、模擬量與數(shù)字量的轉(zhuǎn)換等組成。主要用于實(shí)現(xiàn)轉(zhuǎn)臺(tái)位置檢測(cè)控制、變頻器對(duì)電動(dòng)機(jī)的驅(qū)動(dòng)以及鍵盤顯示等功能。

The rotomoulding processings Control System Design
Abstract
 The rotomoulding processings development and studies can be trace back to 60's of our country. but the real large-scale industrialization produces still at middle and empress period of 80’s,when lead the forerunner rotomoulding processing equipments and techique from the abroad. Definitely the factory equipments still regard importing as the lord mostly. So research to manufacture for the design that    rotomoulding processing have the social meaning.
  This design of the system,is control with the microcontroller toconduct and actions.Use trasduer to control he machine,accepting the D/A outputting of the microcontroller as the date of the trasducer,woke with the date. .Position examination adoption use position inverter.
Microcontroller control the electric circuit is main from the one 8031 and procedure saving machine and data saving the machine expand, imitates the deal constitutes with conversion etc. Used for realizing to turn the set position examination the control and trasducer to drive to the electric motor primarily and keyboard manifestation etc.

Keywords: rotomoulding processing trasducer microcontroller Inverter
