摘要
研究了TEXAS公司的TMS320F2812的ADC(Analog-to Digital Converter)的工作原理;根据电力系统微机继电保护中对多路电压及电流信号的采样精度和速度的高要求,结合TEXAS公司关于TMS320F2812的校正方案,介绍了利用软件程序对芯片TMS320F2812中内置ADC采样校正的软件实现方案,通过试验进一步验证了该方案的有效性。所提出的方案对电力系统自动控制装置的软、硬件设计具有一定的参考价值。
This article has studied the principle of TEXAS Corporation＇s TMS320f2812 Analog-to-Digital Converter（ADC）. According to the critical request of sampling speed and precision of power system microcomputer relay protection , the software realization plan about TMS320F2812 ADC sampling adjusts has been introduced under the help of TEXAS calibration plan. This plan＇s validity has further been confirmed through an experiment. Plan proposed here could take some reference value to design of power system automatic control devices.
