Reaction vessel temperature control system design
Abstract
Introduced the lesson a background of this lesson and study meaning and finished functions in introduction first .
This system is made of AT89C51,74164,ADC0809. The ADC0809 is used to check and given voltage current and input voltage. Heated oil control the temperature and the EG gas control the pressure, using PID algorithm.
This system state the chose of components, chips, design of hardware circuit and system software in detail. It includes main program, interrupt service routine and many subprograms.
This system has so many characters, such as ,high precise, better ability, advanced and convenient use and so on, It has already get the abnormal achievement in the area of industrial contiolling .
The text inside describes the system hardware work principle in brief first, and attach with the system hardware design frame diagram, combine development history that introduced the single a machine microprocessor, discuss this graduate design a function for applied each hardware connecting a people the technique connects with each one a mold piece and work processes
