实时性强

检测精度够达到0.7%。

Abstract

A new subway speed sensor detection system that can detect both type of photoelectric and Hall speed sensor is designed

with PCI—8348AJ high speed paralleling data acquisition card as the core

by using V20 inverter to control motor speed

simulate performance of speed sensor under different speed. The software is written in VC + +

it mainly includes calculating speed according to value of wheel diameter

signal period

duty cycle and phase drift. Using TQG19 Hall speed sensor as detection device

it is proved by experiment

the detecting system has high stability

strong real-time performance

practical

precision can reach 0. 7 %.
