摘　　要：阐述了移动制氧设备的基本组成,提出了移动制氧设备控制系统的方案,设计了控制系统硬件电路与系统的控制软件。该系统以MCS-51单片机为核心,采用模糊PID控制方法对制氧装置压缩机、分子筛控制电机进行控制,从而对相应环境中的氧分压进行监测控制,并可使其参数保持在所设定状态,以实现其特定的用途。实验表明,控制系统能完成对氧分压的精确测量和稳定控制。In view of the basic composition of the motion oxygen making equipment, the programme of control system about the mobile oxygen-making device is proposed and the control system hardware circuit and system＇s control software are also designed. Taking MCS-51 single chip computer as core part, and using fuzzy PID method to control the oxygen-making device compressor and molecular sieve electric motor, the system can measure and control the oxygen content in the specific situation and also keep it on the given value to achieve the specific functions. The results proved that the system has accurate measurement property and stable control of the oxygen content.
