The Design of Furnace Temperature Control System Based
on
Single Chip Microcomputer
Abstract
In the industrial production process, often require various types of
furnace, heat treatment furnace, reactor temperature detection and
regulation, so it needs a proper system of precise control of its
temperature. as low power consumption single chip, high performance,
reliability, easy-to-market commodity and so on, so to control the
temperature using SCM not only save on cost, control method of flexible and
diverse, and can achieve higher precision, which can greatly enhance the
quality of the product, so SCM is widely used in the Small control system.
The automatic control technique is a temperature particularly controls
technique at domestic and international get the extensive application with
develop. Time postpone effect perplex always in fact on the occasion of
applied, for this person invents various controls method to resolve the
problem of Time postpone. This paper introduces a design of temperature
data acquisition system based on single-chip AT89S52. The system collects
temperature data through 1-Wire Digital Thermometer DS18B20, and the
control algorithm of DDC parameters is presented.
This system according to mold a design for turning procedure design
toughing, completing to system software part of designs, giving each
function mold piece thought with flow chart. A function temperature control
system can proceed accurately the data adopts the kind converts,
stabilizing the proceeding heat, the control process of the constant
temperature, and can satisfy completely to the request of the system
accuracy. and can show them to the operators by the way of the Liquid
Crystal Display. This system used the present the usage the LCD and actions
output equipments, make data kept the view more. The results of the
simulation show that the system works stably and meets the expected design
