摘　　要：为了解决目前航天产品氮气冲洗工艺中存在的问题,设计了一种基于C8051F040单片机的便携式氮气冲洗装置控制系统。该系统利用触摸屏输入各项氮气冲洗工艺参数;通过Modbus通信协议将相关数据传送至单片机;最终通过单片机实现电磁阀的自动控制和过程数据的采集,完成氮气冲洗工艺。应用结果表明,该系统体积轻便、操作简单、测量数据准确、可靠性高,具有良好的推广价值。To solve the problems existing in nitrogen flushing process of current aerospace products,the control system for portable nitrogen flushing device based on C8051F040 signal chip computer is designed. With this system,the parameters of the flushing process are input through the touch screen; relevant data are transferred to single chip computer via Modbus communication protocol; then the automatic control of solenoids,and process data acquisition are implemented by the single chip computer to complete the nitrogen flushing process. The result of application indicates that the system features lightweight,ease operation,precision data measured,and high reliability,it possesses excellent promoting value.
