Abstract
In recent years along with computer penetration in the social sphere, SCM
applications are constantly deepening, and drives the transmission control system of
detecting change rapidly.In real-time monitoring and automatic control of the SCM
application system, the microcontroller is often used as a core component, only SCM
knowledge is not enough, should be based on specific hardware structure, and the
specific characteristics of the target application software, to make perfect.
the refrigerator is essential in the modern family home appliances. But at present
our country market selling refrigerators mostly using the traditional mechanical type
temperature control, the control precision, single function, has the advantages of
simple control method is difficult to meet the requirements of the development of
refrigerator. With the economic development and people's living standards further
improved, the multifunctional development of increasingly high demand. As the
MCU performance is good, strong control function, reliable work, low cost and other
advantages, is now in the home appliance products has been widely used. Facing the
domestic refrigerator development present situation, the technique is compared with
other developed countries have a certain gap, we in the original basis of the
refrigerator is improved, making it suitable for use in contemporary fashion, energy
saving and environmental protection, intelligent, precise temperature control of the
development mode, make people experience have never even heard of it personalized
feeling, fast and the original is no longer a dream. A new generation of products in
control also increased in artificial intelligence, is home appliance of superior
performance, the use of more convenient and reliable.
Refrigerator temperature control system is the use of temperature sensor
acquisition of refrigerator and freezer room temperature and evaporation
temperature.Through the use of MCU in digital signal processing, so as to achieve the
purpose of intelligent control.This system may realize the electric refrigerator
refrigerator and freezer room temperature setting, refrigerator automatic defrosting,
the door alarm function.
The design of the second chapter discusses the hardware design part.The third
chapter discusses the system software design.
Based on the direct cooling type refrigerator cooling system improvement and
using fuzzy control technology to realize the refrigerator, double temperature double
control, make refrigerator according to use conditions change rapidly and reasonably
adjusting cooling capacity, and the energy saving effect is good.
Key words：Single chip computer， temperature sensor， refrigerator， temperature
