- 根据权利要求1所述的一种液氮罐无损监测系统，其特征在于：所述误差率的计算方式，包括以下步骤：S1、划归编号：将每个采样底座中的压力传感器进行划归编号，得到每个的压力传感器为X q，l，其中q∈[1，m]，m为大于10的整数；l∈[1，n]，n为大于5的整数；m等于采样底座的数量，n等于每个采样底座中压力传感器的数量；S2、采样排序：将采样底座中对应位置的压力传感器的数值进行排序，得到n组中间值Y i，其中i∈[1，n]；若m为奇数，取排序后的中间值，若m为偶数，取排序后中间位置两侧的数值的平均值；S3、作差作商：将n组的传感器数据与中间值作差，将差值与中间值相除并作绝对值，若则对应的液氮罐为异样。
- 根据权利要求1所述的一种液氮罐无损监测系统，其特征在于：所述液氮罐无损监测系统的使用方法，包括以下步骤：B1、运输组件和采样组件配合，将一批次的液氮罐依次运输至每个采样底座表面，液氮罐质量分布均匀，使得液氮罐平稳放置在采样底座上；B2、摆动装置驱动若干采样底座同步摆动，使得液氮罐中的液体发生晃动，并产生液锤现象；B3、由于异样的液氮罐的内部产生裂纹或泄露，在摆动时，液体对罐体的作用力不同，显示在压力传感器的数值不同，当检测到压力传感器的数值的误差率大于30％时，移载机械手移动至异样的液氮罐位置，并移载至分拣传送带上。
- 根据权利要求9所述的一种液氮罐无损监测系统，其特征在于：在所述B1中，待到所述液氮罐中的液体静置后，松开运输组件和液氮罐的连接，使 得液氮罐平稳落在采样底座上。
