摘要
基于ATmega128单片机设计了智能蒸柜控制系统。由于蒸柜系统之前采用西门子PLC,目前这一系列已经停产,为了实现控制系统优化,采用以ATmega128单片机为控制核心单元,取代原来由PLC及触摸屏组成的控制系统,并在软件程序部分将原来的PID算法改进为模糊自整定PID算法。经过软硬件测试,控制系统与原系统相比更简单、准确、稳定、经济、智能,值得在实际应用中广泛推广。
The control system for an intelligent steaming cabinet based on ATmega128 SCM （single chip microcomputer） is designed in this paper. Siemens PLC is often used in the design of control system for steam cabinet, but a series of PLC is not in production. In order to optimize the control system, the proposed control system with ATmega128 microcontroller as the core control unit replaces the former control system which is composed of PLC and touch screen. In addition, the PID algorithm is im- proved to the fuzzy self-turning PID algorithm. Through the hardware and the software test, data acquisition and analysis results with the optimized system show that the improved control system is more simple, more accurate, more stable, cheaper and more intelligent than the original one, which is worthy of popularization in practical application.
