摘要
文章介绍了以AT89C52单片机为核心的飞机发动机智能检测控制系统,通过对转速信号的采集、运算、分析及对步进电机的驱动控制,带动仪表指针转动相应的刻度来检测速度变化,从而实现了速度在线智能检测;给出了系统电路和系统软件的设计方案及采样信号频率的算法。系统具有硬件体积小、成本低、检测精度高、操作方便、智能化较高等特点,应用前景十分广阔。
The intelligent detecting system of aeromotor with AT89C52 single-chip computer as core control is introduced. Rotating the hand of meter through conversion, collection and operation of aeromotor speed signal and the control of step-motor to test the variety of speed is realized the online intelligent detecting of aeromotor speed. Design scheme of circuit and software and the frequency arithmetic of sampling signal are provided. The system has many features including small volume of hardware, low cost, high detecting precision, convenient operating, high intelligent and so on, leading to broad and bright future.
