[来源：http://www.think58.com]
本次设计的铁路信号的采集和处理以ADC0809和8051为核心，该系统有三个部分：数据采集，数据处理和显示，终端接收。具体包括控制、显示、A/D转换器、电平转换接口、个人计算机等。设计中用ADC0809进行8路数据的采样，利用MCS-51单片机的串行口发送和接收数据。显示部分由8155、75452、7407和LED数码显示器构成。硬件设计应用电子设计自动化工具，软件设计采用模块化编程方法。

ABSTRACT
The design of the railway signal acquisition and processing to ADC0809 and 8051 as the core, the system has three parts: data acquisition, data processing and display, the terminal receiver. Including its control, display, A / D converter, power conversion interface, personal computers. Design using ADC0809 data for 8 samples, using MCS-51 microcontroller serial port to send and receive data. Display in part by the LED digital display 8155,75452,7407 and composition. Application of electronic design automation of hardware design tools, software design is modular programming.
