程序员对代码所做的为了满足短期利益代码改动,或再没有完全清楚增个架构下的改动,都很容易是代码失去它的清晰结构,偏离需求或设计。而这些改动的积累很容易使代码偏离它原先设计的初衷而变得不可立即和无法维护。
Refactoring则帮助重新组织代码,重新清晰的体现结构和进一步改进设计。
-programmers to code done in order to meet short-term interest code changes or not entirely clear by a framework of the changes, it is easy to lose its code is a clear structure, depart from the demand or design. And the accumulation of these changes are easier to make code from its original intention of the original design has become an immediate and unable to preserve. Refactoring is helping to reorganize code, re- clearly reflected structure and further improve the design.

常用的说话人识别方法有模板匹配法、统计建模法、联接主义法(即人工神经网络实现)。考虑到数据量、实时性以及识别率的问题,采用基于矢量量化和隐马尔可夫模型(HMM)相结合的方法。
说话人识别的系统主要由语音特征矢量提取单元(前端处理)、训练单元、识别单元和后处理单元组成,
-Commonly used methods of speaker recognition template matching method, statistical modeling method, and connection method (ie, artificial neural networks). Taking into account the amount of data, real-time as well as the recognition rate of the problem, based on vector quantization and Hidden Markov Model (HMM) method of combining. Speaker recognition system mainly by the voice feature vector extraction unit (front-end treatment), training modules, identification and post-treatment unit modules,

在数控机床中, 通常用可编程控制器( PLC) 对机床开关量信号进行控制。PLC可靠性高, 使用方便。但在大多数数控机床, 特别是经济型数控机床中, 要求的输入输出点数并不多, 通常在60点以下,因此, 为了降低数控机床成本, 在基于工业PC机的数控系统中, 可以采用开关量I/O板加外接继电器,配合主机的软件对机床开关进行控制。但如果PC机采用单任务操作系统(如DOS) , 数控系统的所有任务运行都置于一个总体的消息循环中, 软件的模块化和可维护性较差, 系统故障的风险相对集中, 而且不能充分利用PC机系统资源。而采用非实时多任务操作系统(如Windows) 时, Win32 API的设计没有考虑到实时环境的开发用途, 其系统调用的效率不高,不能满足数控系统PLC控制的实时性要求。
为此, 本文提出一种基于RT - Linux操作系统的嵌入式PLC, 利用RT - Linux的开放性、模块化和可扩展性的系统结构特性和多线程/多任务的系统环境,在保证实时性的同时, 使故障风险相对分散。
