摘　　要：轴角编码器是某指控装备的核心器件,其主要功能是把输入轴的转动角度转变成一个对应的二进制编码。该部件出现的故障频率高且部件脱离系统后修理难度大,因此提出研制轴角编码器自动检测平台的需求。检测平台基于PXIe总线架构,选用多功能多路信号输入/输出采集卡采集轴角编码器的输出编码、采集轴角编码器工作时的转速及扭矩信号;选用程控电源模块提供检测平台所需的供电电源。运用开源测试软件SeeSharpTools开发检测平台应用软件。具备模拟轴角编码器实际工作状态,实时显示转动轴扭矩、转速值,采集编码器旋转角度对应的编码值并显示,并具有测试结果分析及打印测试报告的功能。使用L支架结构安装轴角编码器,满足检测过程中频繁更换被测件的需求,极大提高了该轴角编码器的检测效率。Shaft angle encoder is the core component of a certain command and control equipment. Its main function is to convert the rotation angle of the input shaft into a corresponding binary code. This component has a high failure frequency,and it is difficult to repair after the component breaks away from the system. Therefore,it is necessary to develop an automatic detection platform for shaft angle encoder. The detection platform is based on the PXIe bus architecture. A multi-functional multichannel signal input and output acquisition card is selected to collect the output code of shaft angle encoder,and collect the speed signals and torque signals when the shaft angle encoder works. A program-controlled power module is selected for the power supply required by the detection platform. The SeeSharpTools as the open source testing software is used to develop the testing platform application software. The detection platform can simulate the actual working state of the shaft angle encoder,display the torque and speed value of rotating shaft in real time,collect and display the coded value corresponding to the rotation angle of the encoder,and has the function of analyzing the test results and printing the test reports. The L-bracket structure is used to install the shaft angle encoder to meet the needs of frequent replacement of tested parts in the detection process,which greatly improves the detection efficiency of the shaft angle encoder.
