The functions of this automation system focus on five aspects : data acquisition 、 supervision and control 、 fault isolate and recovery 、 gis 、 data statistic and report . the design project takes the rcs - 9000 series 、 sd ? 9520 and sd - 9630 , which is a new installation that can detect the operation state of the low - voltage current breaker , and send the state to the control room . the other new installation is sd - 9860 , which is the monitor of the cable fault 设计方案中,在采用南瑞rcs - 9000系列、双电公司sd - 9520装置的同时,采用了新开发的sd - 9630塑壳开关运行状态采集装置,检测塑壳开关的运行状态,并将运行状态传回到集控中心(中间站) ;采用了新开发的sd - 9860电缆故障指示器,完成电缆故障的识别;集控中心的设计实现了整个小区配电自动化系统的集中通讯、实时监控、统计与管理功能;高、低压开关实现了自动控制、状态检测和无功补偿等。
This thesis explains the necessity of the character recognition technology of the computer at first , describe the meaning in which the handwritten numeral discerns ; pretreatment technology of handwritten numeral recognition , including two value , line segmentation , word segmentation smooth , removing noising , standardization and thinning are discussed two value concretely discusses whole threshold value , some threshold value , dynamic threshold value and utilize space information to carry on threshold , which are several kinds of common method of choosing threshold value , especially utilize space information to carry on threshold value is describe in detail ; adopting to the foundation of thinning based on mathematics morphology , thinning algorithm of serials same and thinning algorithm of protecting shape are discussed ; afterwards , according to principle ' s diagram of the on - line character recognition , by analyzing the structure feature of the handwritten numeral , this thesis has proposed the online recognition te chnology of the free handwritten numeral based on the stroke feature and the online recognition technology of the free handwritten numeral based on the multistage classifying device . detail narrated noise removing , stroke characteristic definition and discernment , distance criterion of whole word match ; then under the foundation of handwritten numeral segmentation , off - line handwritten numeral recognition is researched . especially minimum distance classifying device , tree classifying device and adaptive resonance ( art ) network classifying device is discussed at the same time , believes degree analyses are introduced to integrate a lot of classifying devices ; at the end , the typical application of the handwritten numeral recognition was briefly narrated , its application in extensive data statistics , financial affairs , tax , finance and mail sorting have been explored 二值化时对整体阈值二值化、局部阈值二值化、动态阈值二值化和利用空间信息进行阈值选取几种常用的阈值选取方法进行讨论,特别对利用空间信息进行阈值选取进行了详细论述;在对通过对基于数学形态学的细化的基础上,讨论序贯同伦形态细化算法和保形的快速形态细化算法;然后依据联机字符识别原理框图,分析了手写数字的结构特点,提出了基于笔划特征的任意手写数字在线识别技术和基于多级分类器任意手写数字在线识别技术,对其中涉及的笔划识别前的噪声处理、笔划间特征量的定义及识别、整字匹配的距离准则进行了详细叙述;继而在对手写数字的分割的基础下对脱机手写数字识别进行了研究,对基于最小距离分类器字符识别、基于树分类器的字符识别、基于自适应共振( art )网络的字符识别分别进行了详细讨论,并引入置信度分析将多个分类器进行了混合集成;最后简单阐述了手写数字识别的典型应用,对其在大规模数据统计、财务、税务、金融及邮件分拣中的应用进行了探索。
To some company ' s increment duty tax burden analysis is through four partial analyses : first , through the company in 2003 and 2004 year finance report form to company ' s management survey , the financial condition carries on the analysis ; carry on the analysis from the financial data statistics and the investment yield rate : according to surveys the time bread flour to put into production the proportion , calculates in the time the end product vermicelli output and the sales volume , thus calculates in the time the due payment increment duty tax amount ; according to surveys the time the unit product electrical energy to consume , calculates in the time the end product vermicelli output and the sales volume , thus calculates in the time the due payment increment duty tax amount 企业的增值税税负率反映的是该企业整体经营收入与税收的关系。长期以来,由于我国现行的增值税对挂面加工企业实行17 %的税率,而抵扣实行13 % ,因此导致高征低扣,这样既加大了该企业的生产成本,又制约了其生产经营。而目前的这种税负情况已成为该行业的普遍情况,因此本文的研究对其他挂面加工企业也具有指导和借鉴作用。
