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
 
飛機(jī)電源系統(tǒng)是指飛機(jī)上產(chǎn)生電能的裝置和相應(yīng)配套設(shè)備構(gòu)成的系統(tǒng)。電源系統(tǒng)性能的好壞直接影響到飛機(jī)的飛行安全，它在飛機(jī)各部件中起著非常重要的作用。數(shù)據(jù)不僅是分析處理系統(tǒng)性能參數(shù)的原始資料，，而且也是檢驗(yàn)系統(tǒng)工作有效性的重要依據(jù)[1] [2]。本文設(shè)計(jì)了一種飛機(jī)電源系統(tǒng)的數(shù)據(jù)采集，采用TI公司的TMS320F2812系列DSP。它具有結(jié)構(gòu)簡(jiǎn)單、精度高、可靠性高等特點(diǎn)。
