基于FPGA的实时手势识别系统

基于FPGA的实时手势识别系统张永强;陈香;王从政;董中飞;左鹏飞【摘要】本文构建了一个基于FPGA的实时手势识别平台,并在该平台上实现了一种基于表面肌电(sEMG)信号和加速度(ACC)信号的手势识别算法.具体实现过程中,无线sEMG传感器和无线三轴ACC传感器穿戴于两手前臂实时获取sEMG信号和ACC信号,并以无线方式发送到数据处理模块.数据处理模块充分利用FPGA的并行处理优势,融合ACC和sEMG信息特征,实现了单双手手势的实时识别.经测试,本文所用的手势识别算法移植到FPGA中以后,识别速度明显提高,16个中国手语手势动作达到了95％以上的识别率.%This paper developed a real-time gesture recognition system based on FPGA, and achieved a gesture recognition algorithm based on surface electromyography ( sEMG) and acceleration ( ACC ) signals on the system. Specifically, the wireless sEMG sensors and wireless tri-axial ACC sensors were worn on the arms to collect signals and sent the signals to the data processing module. The processing module took full advantage of FPGA parallel processing,and put sEMG and ACC signal features together to achieve real-time hand gesture recognition. According to the test, the hand gesture recognition algorithm transplanted on FPGA got faster recognition speed than it was run on a personal computer,and the recognition rate for sixteen kinds of Chinese sign gestures reached 95% above.【期刊名称】《传感技术学报》【年(卷),期】2011(024)011【总页数】5页(P1653-1657)【关键词】手势识别;FPGA;表面肌电;加速度【作者】张永强;陈香;王从政;董中飞;左鹏飞【作者单位】中国科学技术大学电子科学技术系,合肥230027;中国科学技术大学电子科学技术系,合肥230027;中国科学技术大学电子科学技术系,合肥230027;中国科学技术大学电子科学技术系,合肥230027;中国科学技术大学电子科学技术系,合肥230027【正文语种】中文【中图分类】TP274.2;TP212.9随着传感器技术、通信技术和IC技术的快速发展，人机交互已经从原来的键盘、鼠标这种单一的交互模式，迅速发展成为融合多种传感器，运用多种通信方式的多样化交互模式［1－2］。

This affords greater reliability and is a more robust application for those instal-lations requiring communications running outdoors between structures. It connects to the RS-232 and RS-485 ports of the FCI 7100and 7200 Series fire alarm control panels. The FLD-1 converts either RS-232 or RS-485 signals to a powerful optical signal that can tolerate a signal loss of up to 10 dB. It uses half duplex data flow, an asynchronous protocol, and runs at speeds of up to 19.2KBps for RS-232 and 128 KBps for RS-485communications.The FLD-1 is equipped with ST connec-tors that will support standard fiber optic cable up to 200 microns (multimode). Opti-mal results can be achieved with 62.5/125micron cable.The FLD-1 provides two modes of opera-tion, the Network Mode or the Point-to-Point Mode, selectable through DIP Switch settings on board the FLD-1.Network ModeUsing this mode the following configura-tions are possible:are not intended to be used for installation purposes Point-to-Point ModeWhen configured in the Point-to-Point Mode, a single 7100 or 7200 Series control panel may use its RS-232 port to connect to a single printer, video terminal or per-sonal computer (PC) via a fiber optic link.Each location requires an FLD-1.INSTALLATIONThe FLD-1 module mounts inside its own steel cabinet, which can be located up to 15 feet (4.6 meters) away, using rigid con-duit. The dimensions of the cabinet are 101/4” W x 10” H x 3” D (26.04 x 25.40 x 7.62cm).Operating power for the FLD-1 is obtained from the 7200 or 7100 panel, and is con-nected to the FLD-1 via terminal block. RS-485 connections are also made via termi-nal block, and RS-232 connections aremade using a standard RJ-11 cable.An ISO 9001 CompanyThe FCI 7200 RS-485 FCINET ® can be exported via Panel Bus Adapter (PBA) or local Keyboard Display Unit (KDU\L) from the main panel contain-ing the System Control Unit (SCU)to up to fifteen remotely located KDUs,Remote Annunciator Units (RAUs), and sub-panels containing the Distributed Intelligent Unit (DIU). Each location re-quires one FLD-1. The RS-485 communication output of the FCI 7100 can be converted to an optical link and brought to as many as five remotely located LCD-7100alphanumeric displays or LDM-7100remote annunciator drivers.

EP1C6Q240C8封装和部分引脚的功能分析

EP1C6Q240C8封装和部分引脚的功能分析图U21A图U21B图U21C图U21D第一部分：封装图U21A、U21B、U21C、U21D表示的是同一块芯片EP1C6Q240C8，有240个引脚，采用的是PQFP封装(即Plastic Quad Flat Package，塑料方块平面封装)，PQFP封装的芯片的四周均有引脚，而且引脚之间距离很小,管脚也很细，一般大规模或超大规模集成电路采用这种封装形式.用这种形式封装的芯片必须采用SMT(Surface Mount Technology，表面组装技术)将芯片边上的引脚与主板焊接起来。

对于SMT技术，个人理解，即表面组装技术，一般用来焊接一些引脚在几百以上的芯片，比如说BGA，PGA一般都采用这种技术;例如笔记本主板上的intel北桥芯片，一般都采用球形封装，又如比较古老的Intel 965底部球形引脚大约有600多个,现在笔记本流行用的P43、P45、P55、X58，从P43一代引脚多达几千个甚至更多,这样做的好处是节约面积，坏处是测试的时候比较麻烦，像BGA这种封装的芯片一般焊上去之后,顶部要引出几个接点，以防止在使用过程中坏掉，方便用万用表或者示波器来测试各个通路便于修理.对于这几种类型的芯片,除了PQFP少数罕见的高手能手工焊接之外，一般都采用贴片机来进行专门的焊接工作。

这里简单介绍一下这两种封装:PQFP/PFP封装具有以下特点1.适用于SMD表面安装技术在PCB电路板上安装布线。

2.适合高频使用。

2.操作方便，可靠性高。

3.芯片面积与封装面积之间的比值较小。

4.Intel系列CPU中80286、80386和某些486主板采用这种封装形式。

这里的SMD表示的是贴片组装器件;BGA球栅阵列封装随着集成电路技术的发展，对集成电路的封装要求更加严格.产品的功能性,当IC的频率超过100MHz时，传统封装方式可能会产生所谓的“CrossTalk（串扰）”现象，而且当IC的管脚数大于208 Pin时，传统的封装方式有其困难度。

SMT锡膏SPI1

DEK机印刷参数设定操作指导书发布时间:2012-07-31 08:12阅读次数:175分类:行业新闻1、定义1.1 良好的锡膏印刷质量需满足的要求：为保证表面贴片元件焊点的可靠性，焊盘上所漏印的锡膏需满足三点要求：正确的位置、良好的外形、合适的锡量。

具体如下图所示：一）正确的位置：锡膏必需印刷在焊盘内，且不能出现连锡，焊盘外不能有锡膏存在。

二）良好的外形：锡膏表面高低差小于一个锡膏的厚度,不能出现拉尖、塌陷、缺锡、多锡等现象。

三）合适的印锡量：如图所示，锡膏覆盖面积A必需大于钢网开孔面积的90%；锡膏厚度C理论值为（钢网厚度+0.025)+/-0.025mm，其实际控制范围根据单板检验科的SPC管制图得出。

1.2 细间距/普通间距：依贴片元件的最小引脚间距，将PCBA分成两类：细间距/普通间距。

细间距对应贴片元件最小引脚间距小于或等于0.5mm。

贴片元件最小引脚间距大于0.5mm为普通间距。

对于单引脚器件，钢网开孔宽度小于或等于0.2mm也可归入细间距。

2、目的为DEK印刷机程序制作过程中的参数设定提供指导。

3、范围DEK印刷机的程序参数设定。

4、工作指引4.1 参数的分类依据程序制作、使用过程中的可调整性，将DEK印刷机的印刷参数分为两类：固化参数、可调节参数。

其中固化参数系指程序中不因印制板的变化而变化的参数。

而可调节参数系指程序中需参照印制板的大小、元件分布、印刷机和钢网的工作状态等实际情况而作调整的参数。

4.2 固化参数的设定固化参数有：印刷模式、刮刀材料、刮刀行程、擦网方式、印刷间隙、驻留高度。

此类参数均采用标准设定，特殊情况下可由工程师予以更改。

标准设定：参数名称设定值备注印刷模式 PRINT/PRINT (单程印刷)刮刀材料钢刮刀 (印锡程序)刮刀材料胶刮刀 (印胶程序)擦网方式 W/V/D (湿洗/真空/干冼，印胶程序用手洗)印刷间隙 0mm (PCB与钢网贴紧)刮刀行程钢网开孔最大宽度(Y方向)+2X(30~50)mm驻留高度 20mm (印锡程序)驻留高度 40mm (印胶程序)4.3 可调节参数的设定可调节参数有：刮刀长度、刮刀压力、印刷速度、分离速度、分离距离、擦网频率。
