摘要
介绍一种飞机发动机转速实时检测与仪表显示系统。论述了以单片机AT89C52为核心的该系统的数据采集部分的设计思想,并对单片机和步进电机选用进行了简要论述。系统操作简便、体积小,性能稳定。主要通过对信号的采集处理与分析,由单片机对步进电机驱动控制,实现了由机械显示仪的指针变化来直观的反映转速变化的目的。
The paper introduces a kind of real-time inspection and aeronautical instrument displaying system of areomotor revving. We mainly discusses the designing approach of system based on chip microcomputer AT89C52. The driver advantages for step motor and single chip microcomputer AT89C52 used in the system are also mentioned .The system acquires signals and makes data processing first, which control stepmotor driving system by using singlechip, then the changes respond on the display unit timely. The system has been finished with the characteristics of small volumes, attainable precision, and strong anti-jamming.
