以数显百分表为对象，通过模拟数字和模拟显示界面，仿真位移监测。数显百分表是通过齿轮或杠杆将一般的直线位移（直线运动）转换成指针的旋转运动，然后在显示屏上进行读数的长度测量仪器。主要实现以下功能：串口通信、实时监控测量值、绘制动态曲线图、公英制转换、实时监控最大最小值显示、数据的读取与保存。-Digital Indicators for the object, to be displayed by the analog-to-digital and analog interface, simulation displacement monitoring. Digital Indicators Usually the linear displacement (linear motion) via a gear or lever to convert the rotational movement of the pointer, and then reading the length measuring instrument on the display screen. Achieve the following key features: serial communication, real-time monitoring of measured values, drawing dynamic graphs, Metric conversion, display real-time monitoring of the maximum and minimum read and save data.
