制氮机控制系统的设计与实现

Design and Implementation of Control System of Nitrogen Generator

在简单介绍用膜分离技术制造高纯度氮气的工作原理及主要技术指标的基础上,提出了基于AT89C52单片机的电气控制系 统,给出了硬件、控制软件模块组成和控制流程。该系统已成功应用在制氮机样机中,实现对制氮机本身的控制及氮气输出监控。试 验证明,该系统运行稳定,能够达到设计要求。

On the basis of brief introduction of operational principle and main technical specification of generating high purity nitrogen by using membrane separation technology, the electric control system based on AT89C52 single chip computer is stated. The hardware, composition of control software modules, and control process are riven. Tne system has been used successfully in the prototype of the nitrogen generator to implement control of the generator itself and nitrogen outlet monitoring. The test shows the system is stable in operation and meets the requirement of design.
