Protein hydrolysis temperature control system based on 89C51 single chip microcomputer
【Abstract】：industrial controllers emerge endlessly, the ability of adapting to the environment has been greatly strengthened. At the same time， the degree of intelligence is also getting higher and higher. Among all kinds of industrial controller, the microcontroller is the core of the industrial controller because of small size, low cost, strong functions and other advantages of occupying a place. PID controller is a controller based on PID algorithm, the controller in many industrial fields have a wide range of applications. For example, food, chemical industry and so on. This paper mainly discusses PID controller in the temperature control applications.
This article mainly disscusses many aspects such us hardware design, software design and the related interface circuit design elaborates influence on protein hydrolysis temperature project by the application of the 89C51 SCM temperature control system design scheme based on design process. From multiple aspects, giving full consideration to the environment factors may cause the system, so as to formulate the corresponding measures to guarantee the system stability. In terms of software design, this design is according to the characteristics of the controlled object, the design of a suitable PID algorithm, in order to ensure the realization of the control function.
