摘　　要：介绍了一种智能在线测厚系统的设计方法,系统采用PIC16F877A微处理器作为控制芯片,外加其他必要的传感器信号调,LED显示电路以及超限报警电路进行设计,系统具备实时厚度显示、超限报警以及厚度自动分检等功能。运用软件编程对A/D采样值进行了误差补偿以及线性化处理。系统具有电路结构简捷、性能稳定、价格低、测量精度高等优点。广泛适合各种需要精确测厚的工业场合,具有较好的应用前景。A design method of a intelligent in-circuit thickness measuring system has been proposed, using Microchip＇s PIC16F877A micro-controller and other necessarily peripheral circuits, such as sensor signal conditioning, LED display, alarm circuit. Linearization process technology has been introduced to minimize the non-liner error of measuring system by program correcting. This thickness measuring system has obviously characteristics of simply circuit, steady performance , low price and high accuracy. This measuring system with good application prospect can be widely used in highly precision industrial measuring.
