Design of the temperature Controller of air conditioner Based on MCS-51
Abstract: With the development of the society, the auto control becomes more and more important. The auto control of the resistance furnace is highly anticipated. Microcomputer and its application has become one of the most important contents and signs in the field of High-scientific technology and new scientific technology, which plays an attractive role in every field in our national economy. The control circuit is for the control of the core 8051. Hardware part of the whole system including temperature sampling circuit, self-excited-type A / D converter, key circuit, driver circuit, timing circuit, and 8 decoder, LED digital display. Realize the basic functions of the temperature conversion. Low cost of this control circuit, functional and practical, easy to operate, must have practical value. This paper discusses three aspects, first of all is the description of the hardware circuit; access this part of the design software; Finally functional implementation.
