摘要

A simple and convenient engine rotate speed test module based on CPLD is accomplished.Each module is completed by using EDA technology and VHDL. The principles and implement qtion of engine rotate speed test and rotate speed simulation are expatiated. Finally, the design scheme is debugged and simulated. The result shows that the engine rotate speed test module is able to gain real time and exactly coUects the engine signal. The speed simulation module can offer the precise signal the system needed. These two module above can achieved the engine rotate speed test of UAV.%开发了一种基于CPLD的简单方便的无人机(UAV)发动机转速检测模块,利用EDA技术.通过VHDL硬件描述语言完成了各模块的设计.阐述了发动机转速测量和转速模拟的原理和实现方法,并对设计方案进行了仿真和系统联调.结果表明:开发的发动机转速测量模块能够实时、准确地采集发动机的转速信号,发动机模拟模块能够精确地提供系统所需频率,能够完成无人机发动机转速检测.
