电子邮件地址：iltonlb@,rcsfreire@alessiot@silvanacunhacosta@摘要：本文提出了一款低成本的小型可变频信号发生器。

该发生器采用串行通信方式，在实际的应用中通过对失聪人员的实时触觉反馈对其进行模式训练。

这个信号发生器是用于修正数字化去电流延迟及对实际的声音信号进行处理。

通过使用该信号发生器，我们将用于触摸端用以生成数字化信号的部分从接收模块中分离出来。

关键词——耳聋，音高，信号发生器，触觉感知。

I 介绍大约在五十年以前，Geldard提出触觉是一直“被忽略的通讯感知”[1]。

他指出虽然视觉系统和听觉系统分别在空间区隔及时间区隔时候利于信息的传递，而人体本身的感觉系统则在两种情况下都可适应。

另一方面，在无法听到也无法看到的情况下，触觉就变得非常关键了。

在Geldard之前有人曾试图用触觉作为一个通信联络的方式。

从XX世纪以来，人们就开始研究对失聪人员采用触觉系统进行声音信号的传递。

人们尝试寻找各种各样的信息转换的方式，并且由此开发出了许多触觉感知装置来帮助失聪人员。

[3]，[4]，[5]在文献[6]里面，触觉感知编码是以葡萄牙语文本开发的，它应用于用来辅助语音教学的音节游戏中，其中设置了以触觉感知为基础的语音参数的转换系统。

这些转换装置在传输感知实验中验证了基准语音频率和元音音节的触觉感知。

但这种转换装置没有被采用在实时系统当中。

由于是触觉感知，为了有助于对基准频率控制的训练，系统没有设置对应于实时系统的寄存器。

但不管怎样，装置中任然设计了帮助通过触觉感知的信息传输来进行语音朗读的系统[7][8][9][10]。

电子信息工程电路编程中的AT89C51单片机译文标题电路编程中的AT89C51单片机AT89C51 In-Circuit Programming 原文标题作者Robert W.Sparks等译名国籍美国斯帕克等W.罗伯特Atmel Corporation原文出处摘要本应用说明的是ATMEL公司AT89C51的电路可编程闪存的微控制器。

为在电路可编程AT89C51的应用提出了与应用程序相关的例子，它的修改要求支持在线编程。

这种方法显示在该应用程序中的AT89C51单片机可通过商业电话线远程改编。

本应用笔记中描述的电路，仅支持5伏电压下编程，需要使用一个AT89C51-XX-5。

标准A T89C51的需要12伏电压。

该应用程序的软件可从ATMEL下载。

总论当不在进行程序设计的时候，在电路设计中的AT89C51设计将变得透明化。

在编程期间必须重视EA/VPP这一脚。

在不使用外部程序存储器的应用程序中，这脚可能会永久接到VCC。

应用程序使用的外部程序存储器要求这一脚为低电平才能正常运行。

RST在编程期间必须为高电平。

应该提供一种方法使得电路通入电源以后，使RST代替主要的复位电路起到复位的作用。

在编程过程中，PSEN必须保持低电平，在正常运行期间绝不能使用。

ALE/ PRO在编程过程中输出低电平，在正常运行期间绝不能使用在编程过程中AT89C5I / 端口是用于模式应用程序，地址和数据选择的，可能要该控制器从应用的电路隔离。

如何做到这一点取决于应用程序输入端在编程过程中，控制器必须与应用电路的信号来源隔离。

带有三个输出状态的缓冲区在应用程序之间插入电路和控制器，同时在编程时缓冲区输出三种状态。

一个多路复用器用于信号源之间进行选择，适用于任何一方的应用电路或编程控制器电路的信号输出端如果应用的电路可以允许端口在编程过程中的状态变化，则不需要改变电路。

如果应电路的状态，必须事先在编程过程中的保持不变，可能在控制器和应用电路中插入锁存。

外文文献及翻译-射频识别(RFID)技术简介

射频识别（RFID）技术简介RFID是Radio Frequency Identification的缩写，即射频识别，俗称电子标签。

RFID射频识别是一种非接触式的自动识别技术，它通过射频信号自动识别目标对象并获取相关数据，识别工作无须人工干预，可工作于各种恶劣环境。

RFID技术可识别高速运动物体并可同时识别多个标签，操作快捷方便。

埃森哲实验室首席科学家弗格森认为RFID是一种突破性的技术：第一，可以识别单个的非常具体的物体，而不是像条形码那样只能识别一类物体；第二，其采用无线电射频，可以透过外部材料读取数据，而条形码必须靠激光来读取信息；第三，可以同时对多个物体进行识读，而条形码只能一个一个地读。

此外，储存的信息量也非常大。

1 RFID的基本组成部分最基本的RFID系统由三部分组成：a)标签：由耦合元件及芯片组成，每个标签具有唯一的电子编码，附着在物体上标识目标对象；b)阅读器：读取(有时还可以写入)标签信息的设备，可设计为手持式或固定式；c)天线：在标签和读取器间传递射频信号。

2 RFID技术的基本工作原理RFID技术的基本工作原理并不复杂：标签进入磁场后，接收解读器发出的射频信号，凭借感应电流所获得的能量发送出存储在芯片中的产品信息（Passive Tag，无源标签或被动标签），或者主动发送某一频率的信号（Active Tag，有源标签或主动标签）；解读器读取信息并解码后，送至中央信息系统进行有关数据处理。

3 RFID技术的发展现状及其应用据Sanford C. Bernstein公司的零售业分析师估计，通过采用RFID，沃尔玛每年可以节省83.5亿美元，其中大部分是因为不需要人工查看进货的条码而节省的劳动力成本。

尽管另外一些分析师认为80亿美元这个数字过于乐观，但毫无疑问，RFID有助于解决零售业两个最大的难题：商品断货和损耗（因盗窃和供应链被搅乱而损失的产品），而现在单是盗窃一项，沃尔玛一年的损失就差不多有20亿美元，如果一家合法企业的营业额能达到这个数字，就可以在美国1000家最大企业的排行榜中名列第694位。

Field-programmable gate array(现场可编程门阵列)1、History ——历史FPGA业界的可编程只读存储器（PROM）和可编程逻辑器件（PLD）萌芽。

可编程只读存储器（PROM）和可编程逻辑器件（PLD）都可以分批在工厂或在现场（现场可编程）编程，然而，可编程逻辑被硬线连接在逻辑门之间。

在80年代末期，为海军水面作战部提供经费的的史蒂夫·卡斯尔曼提出要开发将实现60万可再编程门计算机实验。

卡斯尔曼是成功的，并且与系统有关的专利是在1992年发行的。

1985年，大卫·W·佩奇和卢文R.彼得森获得专利，一些行业的基本概念和可编程逻辑阵列，门，逻辑块技术公司开始成立。

同年，Xilinx共同创始人，Ross Freeman和Bernard Vonderschmitt发明了第一个商业上可行的现场可编程门阵列——XC2064。

该XC2064可实现可编程门与其它门之间可编程互连，是一个新的技术和市场的开端。

XC2064有一个64位可配置逻辑块（CLB），有两个三输入查找表（LUT）。

20多年后，Ross Freeman 进入全国发明家名人堂，名人堂对他的发明赞誉不绝。

Xilinx继续受到挑战，并从1985年到90年代中期迅速增长，当竞争对手如雨后春笋般成立，削弱了显著的市场份额。

到1993年，Actel大约占市场的18％。

上世纪90年代是FPGA的爆炸性时期，无论是在复杂性和生产量。

在90年代初期，FPGA的电信和网络进行了初步应用。

到这个十年结束时，FPGA行业领袖们以他们的方式进入消费电子，汽车和工业应用。

1997年，一个在苏塞克斯大学工作的研究员阿德里安·汤普森，合并遗传算法技术和FPGA来创建一个声音识别装置，使得FPGA的名气可见一斑。

汤姆逊的算法配置10×10的细胞在Xilinx的FPGA芯片阵列，以两个音区分，利用数字芯片的模拟功能。

附件1：外文资料翻译译文大容量存储器由于计算机主存储器的易失性和容量的限制, 大多数的计算机都有附加的称为大容量存储系统的存储设备, 包括有磁盘、CD 和磁带。

相对于主存储器，大的容量储存系统的优点是易失性小，容量大，低成本, 并且在许多情况下, 为了归档的需要可以把储存介质从计算机上移开。

术语联机和脱机通常分别用于描述连接于和没有连接于计算机的设备。

联机意味着，设备或信息已经与计算机连接，计算机不需要人的干预，脱机意味着设备或信息与机器相连前需要人的干预，或许需要将这个设备接通电源，或许包含有该信息的介质需要插到某机械装置里。

大量储存器系统的主要缺点是他们典型地需要机械的运动因此需要较多的时间，因为主存储器的所有工作都由电子器件实现。

1. 磁盘今天，我们使用得最多的一种大量存储器是磁盘，在那里有薄的可以旋转的盘片，盘片上有磁介质以储存数据。

盘片的上面和（或）下面安装有读/写磁头，当盘片旋转时，每个磁头都遍历一圈，它被叫作磁道，围绕着磁盘的上下两个表面。

通过重新定位的读/写磁头，不同的同心圆磁道可以被访问。

通常，一个磁盘存储系统由若干个安装在同一根轴上的盘片组成，盘片之间有足够的距离，使得磁头可以在盘片之间滑动。

在一个磁盘中，所有的磁头是一起移动的。

因此，当磁头移动到新的位置时，新的一组磁道可以存取了。

每一组磁道称为一个柱面。

因为一个磁道能包含的信息可能比我们一次操作所需要得多，所以每个磁道划分成若干个弧区，称为扇区，记录在每个扇区上的信息是连续的二进制位串。

传统的磁盘上每个磁道分为同样数目的扇区，而每个扇区也包含同样数目的二进制位。

（所以，盘片中心的储存的二进制位的密度要比靠近盘片边缘的大）。

因此，一个磁盘存储器系统有许多个别的磁区, 每个扇区都可以作为独立的二进制位串存取，盘片表面上的磁道数目和每个磁道上的扇区数目对于不同的磁盘系统可能都不相同。

磁区大小一般是不超过几个KB; 512 个字节或1024 个字节。

外文文献及翻译-EDA技术及软件

EDA技术及软件EDA是电子设计自动化(Electronic Design Automation)的缩写,在20世纪90年代初从计算机辅助设计(CAD)、计算机辅助制造(CAM)、计算机辅助测试(CAT)和计算机辅助工程(CAE)的概念发展而来。

EDA技术就是以计算机为工具，设计者在EDA软件平台上，用硬件描述语言HDL完成设计文件，然后由计算机自动地完成逻辑编译、化简、分割、综合、优化、布局、布线和仿真，直至对于特定目标芯片的适配编译、逻辑映射和编程下载等工作。

1 EDA技术的概念EDA技术是在电子CAD技术基础上发展起来的计算机软件系统，是指以计算机为工作平台，融合了应用电子技术、计算机技术、信息处理及智能化技术的最新成果，进行电子产品的自动设计。

利用EDA工具，电子设计师可以从概念、算法、协议等开始设计电子系统，大量工作可以通过计算机完成，并可以将电子产品从电路设计、性能分析到设计出IC版图或PCB版图的整个过程的计算机上自动处理完成。

现在对EDA的概念或范畴用得很宽。

包括在机械、电子、通信、航空航天、化工、矿产、生物、医学、军事等各个领域，都有EDA的应用。

目前EDA技术已在各大公司、企事业单位和科研教学部门广泛使用。

例如在飞机制造过程中，从设计、性能测试及特性分析直到飞行模拟，都可能涉及到EDA 技术。

本文所指的EDA技术，主要针对电子电路设计、PCB设计和IC设计。

EDA设计可分为系统级、电路级和物理实现级。

2 EDA常用软件EDA工具层出不穷，目前进入我国并具有广泛影响的EDA软件有：multiSIM7（原EWB的最新版本）、PSPICE、OrCAD、PCAD、Protel、Viewlogic、Mentor、Graphics、Synopsys、LSIIogic、Cadence、MicroSim等等。

这些工具都有较强的功能，一般可用于几个方面，例如很多软件都可以进行电路设计与仿真，同进还可以进行PCB自动布局布线，可输出多种网表文件与第三方软件接口。

英文文献翻译二〇一四年月日科技文章摘译Preventing electricity-stolen smart metersWith the development, it has been increasingly used in smart instrumentation equipment, so that the instrument performance have been greatly improved. This article describes the preventing electricity-stolen smart meters is to the ATMEL AT89C51 microcontroller as the core of the design, it achieves 32 power measurement and touring shows, and other functions, but also preventing electricity-stolen, anti-submarine-moving, high-precision, long-life And low power consumption and other characteristics of the new residential areas and is the preferred meter in the urban network reform.Hardware design(l) Signal acquisition and conversion of the electric circuit is more complicated measures, the traditional way is to sample the respective current, voltage, the AID conversion after their multiplication. This approach is not only to analog circuit design of high demand, the software programming requirements are also high, but it is difficult to achieve multiple users on the measure. Therefore, we choose BL0932B as a signal acquisition and conversion circuit core, it is an electronic power meter ASIC. BL0932B design based on the signal acquisition and conversion external circuit board with simple, high precision and stability, and other characteristics, especially for single-phase two-line power users of energy metering.BLO932B within the buffer amplifier, analog multiplier, VIF converters, counting circuit and drive circuit, can accurately measure positive and negative direction of the two active power and computing power in the same direction. The output in two ways: rapid pulse output and slow output for the former computer data processing, the latter used to drive pulse motor work.As the signal acquisition and conversion circuit board as well as the high-voltage 220 v, there Baidoa v order of magnitude of the small-signal, which requires the printed circuit board design and production process to be very scientific and rational. In addition, in order to protect the motherboard, BL0932B rapid pulse of the photoelectric sent to isolation after the SCM.(2) MCU control circuitSCM control circuit, including analog switch arrays, display and keypad circuit, datastorage, serial communications interface and watchdog circuit.l) analog switch array Preventing electricity-stolen smart meters are centralized meter, the MCU to the multi-pulse signals in real-time detection, therefore, it uses an Analog Switches CD405I of four eight-select and a 3 to 8 decoder 74 LS138 common Composed of analog switch arrays,ang it achieve a 32-way pulse of the cycle of detection.2) And show circuit as a key focus on smart meters, need to show the contents of many. Main form of households, electricity, the status of various instructions and error information. To this end, we designed the LED display, from 10 strings and static converters 74 LSl64 drive so you can at least take up the MCU resources. In addition, the signal input terminal also designed the 25 LED indicator, to display the 25 electricity capacity.The meters are "checking" and "cleared" two function keys are directly linked to the P3 in 89 C51 on the mouth. Through a combination of the two keys, can easily achieve the MCU cleared meter, single households cleared, online check, such as locking and unlocking operation.3) Data storage because of the configuration of the table need to record a large number of important data, in order to ensure data security, we designed the two data memory: parallel data memory and serial data memory. Parallel data memory by 6264, it has SK bytes of storage space, to fully meet the requirements of the table. In order to prevent power-down when the data loss, to the 6264 allocation of the 3.6 v backup battery. Backup battery switch and the 6264 election signals the film, by special worship P MAx691 provide monitoring chip. Serial data memory by 24 LC65, it also has a SK bytes of storage space, and through IZC bus connected with the MCU. Although there is no IZC 89C51 microcontroller bus interface, but through software programming, P1 I can simulate the two lines of its timing, completion of the 24 LC65 read and write operations. 24LC65 is a serial EZPROM, without battery backup, data can be safely stored in 200 years.4) Serial communication interface 89 C51 has a full-duplex serial interface, used in this meter for meter reading and communication interface.
