| 中文摘要: |
| 零点误差是衡量水分天平的重要指标,其直接影响水分天平的称重准确度。 提出了一种基于长短期记忆(LSTM)网络
的水分天平零点误差补偿方法,分析了水分天平零点误差机理,使用历史零点误差数据建立基于双层 LSTM 长短期记忆网络的
零点误差预测模型,采用空载与加载载荷时两种情况分别进行补偿。 利用该模型对 200 g / 1 mg 的水分天平进行现场补偿验证,
结果表明,补偿后的水分天平在空载和加载载荷时,最大示值误差约为 6 mg,远小于补偿前的示值误差,证实了这种方法的有
效性。 |
| 英文摘要: |
| The zero error is an important parameter of the moisture balance, which directly affects the weighting accuracy of measuring
the moisture. A method for compensating the zero error of moisture balance based on long-short term memory ( LSTM) network was
proposed. The mechanism of the zero error of moisture balance was analyzed, and the prediction model of zero error based on the double
layer LSTM was established by using historical zero error data. This proposed model was used to compensate the zero error of the
moisture balance with some loads and without load respectively, where the measuring range of the moisture balance is 200 g and its
resolution is 1 mg. The experimental results show that the maximum error of the compensated moisture balance is about 6 mg, which is
much smaller than before. The experiments have verified the effectiveness of this method. |
