摘要
针对直升机旋翼转速指示系统的特点,以高性能DSP芯片TMS320F2812为核心,采用数字化检测和信号处理技术,对原模拟式旋翼转速信号变换器进行了系统级兼容的改型设计。数字化技术的应用使得系统质量减轻,且精度和可靠性大为提高,实践证明新设计在保留原有电气接口特性的同时又达到了旋翼转速的指示要求。
In terms of the characteristics of the rotor speed indicating system,the DSP TMS320F2812 of high performance is the core component.The digital detection and signal processing are applied to substitute for the analog rotor speed signal convertor.The new design has less mass while better precision and reliability.It is proved that the rotor speed indicating requirement is satisfied but original interface not changed.
