自动化标定测试设备信息交互平台设计与实现

Design and realization for automatic calibration of test equipment information exchange platform

传统标定转台往往依靠设备内部多路滑环、连接电缆以及基于ISA、PCI、PXI或VXI总线的采集卡进行惯测组合信息的传输和提取,转台体积大、成本高、标定流程受限以及测试效率低等因素极大影响了设备的使用性。基于自动化标定测试设备的信息交互平台,采用了嵌入式片上系统设计、通信协议设计、容错处理以及工作模式识别等多项技术,为实现自动化、智能化以及精准化标定提供了新的解决方案。采用新方案设计的自动化标定设备启动后无需再进行计数清零、转位回零以及初始化处理,为缩短标定测试时间(由4 h缩短到1.5 h),灵活的进行标定测试走位以及流程编排,降低转台成本(12路滑环减少到2路),减小设备体积以及准确获取惯测组合信息提供了重要技术保障。

On traditional demarcation turntable,the transmission and the extraction of the inertial integrated information usually depend on the multi-channel links,the tie cable as well as the gathering card based on ISA,PCI,PXI or VXI bus.However,the usability of equipment is significantly influenced by the turntable＇s big size,high cost,low test-efficiency,and restricted demarcation flow.In this paper,a new solution scheme is provided based on the information exchange platform of automated calibration test equipment.It adopts the embedded system-on-chip design,communication protocol design,fault tolerance and work pattern recognition and many other technologies for automated,intelligent and precision of calibration.The automation calibration equipment with the new design do not need the processes such as resetting the counter,turning back to zero and implementing initialization after starting up,and this provides the technical supports for shortening the calibration and test time（from 4 hours to 1.5 hours）,flexibly calibrating the test procedures,reducing the cost of turntable（12 slippery ring road reduced to 2）,reduce the equipment size,and obtaining accurate integrated measurement information.
