Temperature Control System Based On The Monolithic Integrated Circuit8051

The computer profession emerges in several dozens years, in national economy national economy to leading role. As a microcomputer important branch, the monolithic integrated circuit development is rapid, the application domain expands day by day, specially in domain and so on in industry observation and control, intelligent measuring appliance, integration of machinery product, electrical appliances obtained the widespread application.The temperature control has the important status in the current work control. This design take the microprocessor as the center, the design, debugs a temperature control system, the realization temperature intelligent control. This article introduced by the monolithic integrated circuit8051in the temperature control system overall design for the core (are partial including hardware part and software). MCS-51MCU has a structure and system integrity, instruction system with perfect functions and the internal register of standardization and other characteristics, in the Chinese market has been the mainstream chip. Learning and mastering its application would be for future work and lay a good foundation for learning. Computer interface technology is the key technology of It plays a communication peripheral device with the central processor bridge. It is to enable the use of computer interface technology is widely applied in every field of social production departments.This system has an automatic way of the temperature controls. The system measures and changes on real time in temperature controls through temperature sensors (PN temperature sensors) and8A/D switching devices, then sends them to CPU comparing with the advance values and sends out the silicon control to adjust temperature so as to realize the close ring controls. The4×4keyboard to realize people alternately with computer and the LED district can show the temperature in time, control temperature value in real time. System functions include data acquisition, data processing, output control. In0-100degrees C within the scope of a variety of electric heating furnace temperature of precision measurement, at the same time, four LED display direct tracking shows the temperature of a controlled object value, high precision, clear display, stable and reliable, easy to use (in the specific design, the debugging process, to facilitate debugging, the temperature programming in a range ofO to100 degrees C, the control precision is0.5).This text has introduce the operation and design principle of each interface circuit in every part of this system in detail, And has carried on the detailed explanation to the every part of the software. The pager has certain reference meanings to the similar temperature control system. At the same time, the system can also be through interactive input preset value and precision, easy to operate, the advantages of stable performance, in which ADC0804single chip use, greatly reduced the hardware part of the resources than previous designs, it has many advantages.
