Title :Design of Concrete Burdening Automation Control Systems Base on 89C52
Abstract
The dissertation discusses the design of concrete burdening automation control systems base on 89C52.
With the development of automatic control technique, a large number of domestic enterprises have designed some concrete compounding materiel machines. Even so, some concrete compounding materiel machines of domestic market exist some problems,for instance,the weigh error is much,or the function dependability is very low. Therefore,We work out the following concrete compounding materiel automatic control system with the control of 89C52.
The work process of concrete compounding materiel automatic control system introduced in this dissertation is: Setup the parameters, and the parameters are being deposited to the memorizer. And then startup the system,the signal of sensor are being magnified by instrument amplifier, and then being transformed into frequency signal by V/F .After Insulating by the high speed coupling machine, then the signal are sent to the counter. At the same time, the display shows the numerical value of weight ever and again. When the geodesic numerical value of weight less then the enactment, the single chip control the start-up of the materiel transportation strap electromotor by high speed coupling machine and the drive, until the geodesic numerical value of weight is equal to the enactment, the electromotor stop. Then we can start-up the weight of anther materiel.
Because single chip assemble language is important part of automation and its relation is close to the design of hardware, so the dissertation apply this assemble language. We also use the software tools just as Protel and Word.
