Controlling And Managing System For Non-heatsensor,non-measuring-transducer Draw Roll

With the development of science and modem industry,on oneside,high demand is set for production craft and quality; at the sametime,in order to adapt the competition of market, decreasing the cost,reducing the price of product also become one of developmentdirections． The dissertation is mainly concerning about tempraturecontrolling system of Draw roll with a new style．In comparison withthose past styles,its advantage is noticeable──the temprature sensorPt100 and a rotating measuring value transducer are not taken intoconsideration,while the temprature value is got by detecting the currentthrough heating coil(changing 10 percent in total)．As a result,itsproduction craft is simplified,the accuracy is improved and the cost isdecreased． In addition,the visible management of produce process seems to becoming very popular．Our computer managing system can display kindsof values on－line,acquire data on－line,record data and display themconcentratedly. At the same time,it is beneficial to optimize andmonitor the process on－line,etc． The thesis's main contents are the 8031 control system and thecomputer control system．It has been proved that the system can meetall requirements of product by practice The product is good quality and much cheaper than the old ones．Wethink it can cover the very market．...
