基于ARM的三相交流转辙机数据采集系统

本论文针对提速道岔三相交流转辙机电功率测量进行研究与设计.硬件设计以嵌入式处理器ARM为主要控制芯片,在最小系统基础上外扩液晶显示.该提速道岔电流功率采集器可分别对道岔系统的电参数进行测量,包括电压、电流及功率的测量,并可通过判断开关量来输送功率曲线.输出通过RS-485通信接口传送,可以与PLC、RTU等终端直接组网.

Data Acquisition System of three-phase AC switch machine based on ARM

In this paper,it was researched and designed of the power measurement for the three-phase AC point machine of the speed-raising turnout.With embedded processor ARM as the main control chip,and on the basis of the Minimum System,was added a LCD display.This current power collector of speed-raising turnout could measure the electrical parameters of the Turnout System,including the voltage,current and power,and it could be judged through the switch for the transmission of power graph.It sent data through the RS-485 communication interface,with PLC,RTU and other terminal to networking.
