轴角编码显示器的设计及模块电路的应用

介绍某维修测试台编码显示器的设计及模块电路的应用，采用高集成化电路完成该维修测试台轴角编码显示的功能，不但缩小了体积，比用分离元器件设计的电路器件数减少了90％左右，且给电路的设计，加工，调试等带来了很大的方便，改善了电路的可维修性，进一步增强了电路的可靠性。

Design of Shaft Angle Encoder Indicator and Its Modular Circuit

This article introduces the design of shaft angle encoder in a maintenance test bench and its modular circuits. Using integrated circuits to perform the display of shaft angle data, this indicator features smaller size and reduced number of elements, 90% less than the discrete circuit has. These features not only greatly facilitate the circuit design, processing and test but also improve its maintainability and reliability.
