摘要
针对传统计量保障方式容易导致不足计量和过剩计量的问题,提出了自动测试系统的视情计量保障方法.规划了自动测试系统的视情计量保障体系;进行了自动测试系统的溯源性设计;分析了校准数据的特征;建立了校准间隔优化模型;并且在两次校准间隔期内采用测量过程控制方法,全面监控自动测试系统的量值状态.实验表明,自动测试系统的视情计量保障在一定程度上缓解了不足计量和过剩计量的矛盾,提高了计量保障效率.
For the problems of lack calibration and superfluous calibration caused by traditional metrology and assurance ways, a condition-based metrology method for automatic test systems was proposed. Firstly, the system of condition-based metrology was established. Then, according to calibration requirements of automatic test systems, the traceability design was presented. After historical calibration data were analyzed, calibration interval optimization models were proposed. Furthermore, the measurement process control was also used during two calibration＇s intervals to monitor quality values. Experiments show that the condition-based metrology improves the metrological efficiency of automatic test systems.
