摘要
根据GJB1865-94《非线绕精密电位器总规范》中电位器寿命的试验要求,设计了一种基于PIC18F4431作为控制核心、以超声电机驱动的电位器寿命试验控制器,同时采用LM2678和MC33063作为调压主模块,上位机软件为主操作界面,实现电位器寿命试验系统参数的预设置、运行情况的实时监控,具有操作方便、加载电压、旋转速度精度高等优点。
According to the requirement of test GJB1865-94 ＂non wire-wound precision potentiometer general specification＂ in life, we design a potentiometer life test device, it is driven by ultrasonic motor and controlled by PIC18F4431 as controlling core using LM2678 and MC33063 as voltage regulating main module, using host computer as operation interface, it has function for parameter pre-setup and real-time monitoring etc. it is convenient to operate, and it is high accuracy to control the output voltage and rotation speed.
