随着微电子和微机械加工技术的发展,研制尺寸小、重量轻、功耗低、响应快且与IC集成的位移传感器成可能并受到重视。在国内,对半导体研究已经深入研究,在此类传感器的研究中,针对传感器的响应及各种性能指标的测试研究具有非常重要的意义。
本系统利用计算机自动控制技术,将检测过程完全自动化,实现对位移传感器的自动测试。在认真研究位移传感器工作原理的基础上,本课题是基于单片机对位移传感器的自动测试系统硬件设计。目前对位移传感器的测试常采用光栅尺同步移动测量法,以长光栅尺的位移量为基准,测量出传感器的位移量。同时通过传感器的输出信号经过A/D转换得到相应的电压值。根据测试数据以光尺的位移量为横轴,传感器输出的电压量为纵轴,绘制得出位移电压曲线,通过数据处理得到误差从而判断传感器的性能是否合格。 通过本次毕业设计的自动测试系统,实现了单片机对位移和电压的测量,并且有自动判断功能。但由于单片机对数据处理能力有限,需传输数据到PC机才能提高测试精度。本文数据处理取均匀的十个测试点,判断其线性度是否符合标准。大蒜破瓣机

smartthreadsAbstract
With the microelectronics and micro-machining technology, the development dimensions, light weight, low power consumption, fast response and the displacement sensor and IC integration and attention as possible.In China, research has in-depth study of the semiconductor, in such a sensor in the sensor's response and performance testing of a variety of very important significance.
The system uses computer control technology, the detection process is completely automated, the displacement sensor to achieve automated testing.A careful study of the displacement sensor based on the principle, the subject is the displacement sensor based on single chip automatic test system hardware design.Test the current displaceme破碎机锤头铸造工艺
nt sensor is often used grating moved at the same measurement, the long grating displacement as the benchmark, to measure the displacement sensors.At the same time through the sensor's output signal through the A / D converter corresponding voltage.According to the test data to light foot displacement is the horizontal axis, the sensor output voltage amount of the vertical axis, draw the displacement-voltage curves obtained by data processing by the error sensor performance and thus determine eligibility.
