The Automatic Control System in Temperature in Melting Resistance Boiler
Abstract
What this text design is a automatic control in temperature in melting in resistance system. That system makes use of the single a machine can realizes expediently to the parameter of PID choice and set up; Realize industry process inside PID control. It adopts the temperature spreads to feel the actual the temperature of boiler A/ D that machine thermocouple will examine converts, sending into the calculator inside, proceeding with initial value the comparison, having to out the deviation. Press PID regulation to proceed the adjustment to this deviation, beg to should of the control measures control solid after electric appliances, from but regulate the heating power of the electric stove, from but realize to the control of the temperature of boiler. Make use of 8751 single a machines realizes the temperature intelligence controls, can complete automatically the data collect, handles, convert, combine the proceeding PID control to handles( the correction of each parameter number) with the keyboard terminal and manifestation, should notice in control process, adopt the kind period can't be too short, making regulate the process otherwise too multifarious, not only carry out the organization can't respond, but also the utilization of the calculator is big for lower; Adopt the kind period too long, interference can't on time dissolve, make regulate the quality descent. Single a machine is in each profession control system of widespread adoption, its component and solid hour controls the day in system perfect, make that temperature control the total function of the system to increases consumedly, the function is gradually perfect.
The system represses the ability of the interference signal stronger, is too more accurate to the diagraph of the temperature. And pass the PID control calculate way to regulate to the system parameter, the system responds to more prompt, and accurate.
