摘　　要：为了解决遥测系统供配电单元的稳定性与可靠性,设计了一种以FPGA为数据处理器的高精度采集系统,利用减法电路的设计研究了电压转换技术,经过ADC转换对多路配电电压进行采集并实时处理多路遥测信号,通过串口传输至上位机,完成实时监测工作状态的目的;着重阐述了对配电的高进度采集电路的设计、RS422数据传输模块发送与接收的设计与实现以及传输过程中UART内核所实现的功能。经大量测试表明该方案稳定、实用,满足系统的实时性要求。To solve the power distribution unit＇ s stability and reliability, this paper introduces a design of a high precision data acquisition system processor about FPGA, it studied the voltage conversion by using subtraction circuit design techniques, colleting multi-cbannel acquisition and disposing real--time multi--channel telemetry signal processing. It transferred the data to computer, completed the real- time status monitoring. The research stressed the acquisition and distribution of high progress Circuit Design, describing the transmission and implementation of RS422 data transmission module and receiving the process and the UART core functions. After a lot of tests, it showed that the scheme is stable, practical and meets the design requirements.
