摘要

由于目前微位移检测系统的测量精度受到A/D的限制

为进一步提高测量精度

讨论了多周期同步测量法在微位移检测中的应用

并设计了基于单片机控制的微位移检测电路.实际应用表明

在对实时性没有严格要求的情况下

当检测量程为±2 mm时

系统检测精度可达0.1μm

并且通过提高计数频率

系统可以达到更高的测量精度.

Abstract

The accuracy of micro-displacement measurement system is restricted by A/D acquisition at present.In order to further enhance the measuring accuracy

a micro-displacement measuring system based on multi-cycle synchronous measurement is designed with a single-chip microcomputer as the core of test and control circuit.Practical application shows that under low real-time demand condition

measurement accuracy of the system can reach 0.1 μm when the measuring range of inductance dis-placement sensor is ±2 mm

and higher measurement accuracy can be achieved with the counting frequency increased.
