基于导电塑料传感器的连续测角系统设计

Design of Continuous Angle Measurement System Based on Conductive Plastic Sensor

摘要:

介绍了一种基于双联导电塑料传感器可连续测角的数据采集系统，理论角分辨率可达0.1?。系统主要由低功耗单片机、0功耗串口电路及显示部分组成。单片机控制自带ADC12模块进行数据采集，采集完毕即进入低功耗休眠状态，并可由定时中断唤醒。通过对双联导电塑料传感器进行双通道数据采集及算法设计，不仅避免了传统光电编码器存在体积、质量大，对灰尘，电磁环境等条件要求高的问题，而且解决了传统导电塑料传感器无法实现0?～360?连续测角的难题。该系统具有精度高、功耗低、体积小、扩展性强的特点，在工业控制、智能机器人和状态监测等领域的角位移量测量中有重要的应用价值。

Abstract:

This paper introduces a data acquisition system for continuous angle measurement based on double conductive plastic sensor, and its angular resolution is up to 0.1°in theory. The system is mainly composed of a low power MCU, 0-power consumption serial circuit and display part. Single chips control the inner ADC12 module for data acquisition, then enter into low-power sleep state and can be awakened by timer interruption. By the dual-channel data acquisition with double conductive plastic sensor and the algorithm design, the large size, heavy weight and high demand of dustproof and electromagnetic environment of traditional photoelectric encoder are avoided, and 0 ° ~360 ° continuous angle measurement is realized, which could not be done by the traditional conductive plastic sensor. This system has the characteristics of high accuracy, low power consumption, small size and strong extensibility, which has important application value in angular displacement measurement for industrial control, intelligent robots and condition monitoring.
