摘　　要：针对当前煤矿井下高压配电装置的微机继电保护数据采集系统存在实时性差的问题,文章提出了一种基于TMS320LF2407 DSP芯片和14位A/D芯片MAX125的矿用高压配电装置实时数据采集系统的设计方案,详细介绍了系统锁相环、数据采集等相关硬件电路的设计,编制了系统软件。实验证明,该系统数据采集实时、准确、可靠。In view of the problems that the data acquisition system of microcomputer relay protection of underground high-voltage distribution device has not good real-time ability, the paper proposed a design scheme of real-time data acquisition system for mine-used high-voltage distribution device based on TMS320LF2407 DSP and 14-bit A/D chip MAX125. It expounded hardware circuit design of PLL, data acquisition circuit and the system software. The experiment result showed that the system has good performance such as real-time, accurate and reliable in data acquisition.
