在线进行物理量的校准, 就是最大程度地还原各项仪器设备的原始状态, 从中抽取需要校准的物理量, 包括力值、扭矩、速率、位移等, 使用相匹配的标准装置进行相关物理量的量值传递。首先简单介绍了在线校准与实验室校准的区别,并通过具体案例介绍了在线校准的实施过程; 然后阐述了在线校准过程中所面临的诸多问题与实际困难; 最后,对在线校准的未来发展进行了展望。

On-line calibration for multi-parameter, is to fully restore the original state of the instruments, based on which the multi-parameter can be extracted and calibrated with matched standard devices, such as force value, torque, speed, displacement, etc. First, the difference between online calibration and laboratory calibration was briefly introduced, and the implementation process of on-line calibration was exemplified through the specific case. Then the problems and practical difficulties during on-line calibration were described. Finally, the future development of on-line calibration was prospected.
