【摘要】 电流卡片是管理人员管理电潜泵井 ,分析井下电动机工作状况的主要依据之一 ,通过人工读取电流卡片去判断电潜泵井工况时 ,存在人为误差和效率低等缺点。为此 ,在简要介绍基于模式识别的特征提取方法的基础上 ,提出了一种电流卡片的特征提取方法 ,利用VisualC+ +语言编程去识别电流卡片从而判断电潜泵井工况 ,并通过标准的电流卡片对其加以适当的补充 ,从而完善并充实电流卡片特征库。该方法不仅是传统方法的延伸 ,而且可以较大程度地提高电动潜油泵的诊断精度更多还原

【Abstract】 When the working conditions of ESP (electric submersible pump) are judged by reading the current cards artificially, there exist personal errors and it is low efficient. After a brief introduction of the character pick-up method based on pattern recognition, a character pick-up method of current cards is put forward. VC programming is adopted to recognize the current cards for ESP’s working condition judgement, implementing by standard current card, therefore improving the character database of the cards. This method can improve the diagnosis accuracy of the ESP to a certain extent.更多还原
