摘　　要：介绍一种人机交互系统的可靠性设计方案。该系统基于Memory-link通信协议,采用了目前流行的基于ARM7架构的S3C44BOX作为主控芯片,通过RS-422实现人机交互通信。结合抗干扰的硬件设计和稳定有效运行的软件设计方案,实现了在强干扰下稳定可靠的通信。实验结果表明,本系统抗干扰能力强、运行稳定可靠,在自主开发控制系统的人机交互通信部分具有一定的参考价值。A reliability design plan of the system about a human-computer interaction is described. The system is based on the Memory-link communication protocol,S3C44BOX as the main chip is based on a popular ARM7 architecture, Man-machine interactive communication via RS422.Combine anti-jamming hardware design and stable efficient running of the program＇s software design, to achieve a stable and reliable communications in strong interference. Experiments show that this system is anti-jamming stability, stable and reliable, human-computer interaction communication part of the serf-developed control system has a certain reference value.
