Abstract: Aircraft aircraft power supply system is one of the important support system.With the increasing performance of aircraft, aircraft power system quality and reliability of power supply a higher demand .This paper introduces multi-channel data acquisition system design based on TMS320F2812. The system use TMS320F2812 DSP chip to achieve real-time multi-channel data acquisition and processing.Data transmittes through RS-422 to the host computer on a concrete analysis of the data. The system is simple structure, high reliability, flexibility and low cost.
Key words: Digital Signal Processor(DSP); Data Acquisition;RS-422飞机电源系统是指飞机上产生电能的装置和相应配套设备构成的系统。电源系统性能的好坏直接影响到飞机的飞行安全,它在飞机各部件中起着非常重要的作用。数据不仅是分析处理系统性能参数的原始资料,,而且也是检验系统工作有效性的重要依据[1] [2]。本文设计了一种飞机电源系统的数据采集,采用TI公司的TMS320F2812系列DSP。它具有结构简单、精度高、可靠性高等特点。
