| There are hundreds of manadeoard factories in our country at present. Most factories?scale is small, but almost of them have their own makingæ¢dhesive work room to meet the manufacture need of their enterprise. The manufacture is still in the period of handperated, and also the product equipment is out of date, so the quality of made adhesive is extremely unstable. Sometimes it will cause adhesion, stopping product and even lead to unpredicted incidence such as the adhesive breaking out of pot etc with the fault operating of the workers. What more, it will cause the greater loss. So it is very significant to research a cheaper adhesiveroduct temperature control system.. Although the history of making adhesive has several decades, yet its reaction principle is still unknown up to day. So it is difficult to build accurate maths rnodle. With the deep analysis of the adhesive in the course of its production, it can be found that the adhesive product has the character of noniner, timeary and capacitorelay. So fuzzy logic technique is adopted in the control calculator. With the logic control , 8051 microontrol unit is selected as the microrocessor which makes the calculator simple and easy. In the detect of the tempreature DS1820 is used as digital sensor. DS182O adopts the way of special sigleus dataransmission.,although this will increase the difficult and the work amount of make procedure .while this simples the design of hardware and also decrease the cost . The technology of adhesive product is improving step by step, so the system permits user inputs technology parameter in the plot with keyboard. The inputted parameter will stay in the EEROM for ever untill new parameter is inputted. The adhesive product surroundings is much worse. The disturbance from electromotive, electromagnetism valve, relay etc largely lie in the course. So somemeasure of anti--disturbance is used in the course of the hardWare andsoftware design.Because of some kinds of reasons, in the experiment adhesive whichis replaced by water is used at last. The conclusion of the experimentis given in the artic1e. |
