Abstract
As electr onic tech no logy and the rapid developme nt of micro-computer,
computer measureme nt and con trol tech no logy has bee n rapid developme nt and
wide application. The use of computer monitoring and control of the temperature of the
tech no logy, will also be followed by stude nts and the developme nt and perfecti on of
the growing, more and show its advantages.In the human living environment, the
temperature plays an extremely important role. people in their daily lives and in dustrial
product ion that the requireme nts of temperature risi ng
,
temperature mon itori ng and
con trol system gradually into people's lives. Temperature con troller has become
increasingly essential to people's lives in supplies. Therefore, the optimal design of a
technique first, equipment, mature and economical temperature con trol system in livi ng
and in dustrial .Temperature is commo nly found in in dustrial product ion, one of the
process parameters,a ny physical cha nge and chemical react ion process is closely related
with temperature, so temperature control is an important task for automation.
The water temperature control applies widely in the industry and the daily life, the
classificatio n are many, the differe nt water temperature con trol system's con trol
method is also differe nt, this desig n the water temperature in tellige nt con trol system
which controls based on the 80C31BH monolithic integrated circuit, introduced the
system in the hardware and the software aspect's design concept, take the 80C31BH
mono lithic in tegrated circuit as a core, has used temperature sen sor AD590, the water
temperature con trol system which by the PID algorithm con trol as well as the PID
parameter installation, unifies the control method which realizes. Has established the user
operati on con tact surface, the con stituti on mini ature supervisory system, en ables the
water temperature change situation to be possible to carry on the dynamic dem on
stratio n, and can by establish artificially in certa in scope.
