[系统设计方案] Graphic-equalizer-circuit

用于控制音质的NF型调制控制电路,因仅能进行低音和高音的增强和衰减,所以不能进行细微的频率特性的补偿。述有,如果想使可听频带域的任意频率均可变,一般使用被称为图形均衡器的装置。这里使用DSP的例子在不断增加,如果要使用简单的电路则使用OP放大器较好。这种图形均衡器是将补偿的中心频率分割为5~7份,分别进行控制,由5个RLC电路组成,十分实用。分割的各个频率是以可听频率范围为对称轴均等分配而决定。
NF-modulation control circuit to control the sound quality, bass and treble enhancement and attenuation, it is not due to only subtle frequency characteristics of compensation. Described there, if you want the audible frequency band domain at any frequency can be changed, the general use of the device is called a graphic equalizer. Example of using DSP is increasing, if you want to use a simple circuit using OP amplifier is better. The graphic equalizer is the center frequency of the compensation split 5-7, respectively, to control by five RLC circuit is very useful. The split frequency is audible frequency range for the axis of symmetry equalization allocation decisions. (2012-06-13, C/C++, 219KB, 下载6次)

[系统设计方案] FrequencyHoppingTechnology

在无线通信中使用跳频技术是军事通信中最主要的抗干扰手段之一, 而如果系统中能使用合适的中心频率可以快速跟踪跳频变化的带通滤波器将可以明显改善系统的抗干扰性能。文中从实际应用出发, 比较了几种可用于实现带通滤波器快速变频的方案, 选择了简单、实用的开关电容阵改变带通滤波器中心频率的方案
The use of frequency hopping in wireless communication technology is the most important anti-jamming in military communications, one of the means, and if the system can use the appropriate center frequency can be fast-tracked changes in frequency-hopping band-pass filter will be able to significantly improve the system anti-jamming性能. This paper from the actual application, the comparison of several band-pass filter can be used to achieve the rapid conversion of the program, choose a simple, practical switched capacitor array to change the center frequency of band-pass filter program (2009-12-22, C/C++, 233KB, 下载119次)

提出了一种基于CCD图像的塑料齿轮齿形缺陷检测方法。采用A102FCCD数字摄像头采集塑料齿轮的图像, 经 过IEEE1394数字接口卡传输到计算机。对含有噪声的原始数字图像实施平滑处理、图像分割、轮廓提取及细化等处理, 使图像转变成易于检测的单像素宽边缘信息。检测了齿轮中心孔的圆心, 进而对齿轮齿形缺陷进行检测。理论分析及实验 结果表明该方法检测速度快、精度高, 满足产品在线检测的要求。
A CCD image of the plastic-based gear defect detection methods. A102FCCD using digital camera images collected plastic gears, the transmission IEEE1394 digital interface card to a computer. Containing the original digital image noise smoothing the implementation of treatment, image segmentation, contour extraction and refining, such as treatment, so that image into a single easy to detect the edge information pixels wide. Detection of the gear center hole of the center of a circle, and thus gear defect detection. Theoretical analysis and experimental results show that the method of detection of high speed and accuracy to meet the requirements of product-line detection. (2008-06-04, C/C++, 382KB, 下载104次)

[系统设计方案] net-game-servers-design

优秀硕士论文《网络游戏服务器集群的设计和实现》,本论文立足于网络游戏服务器端的开发,在借鉴前人设计的基础上,将网络游戏服务中所普遍需要的几大功能进行分解、实现并进一步将它们构建为服务器集群。对“如何稳定地协调游戏服务器与各功能服务器并同时给游戏玩家以较完美的游戏体验?如何利用服务器集群来将维持整个虚拟游戏世界运转的任务分配到不同的计算机?如何达到降低单台计算机的负载,更好的保证网络的稳定性和通讯的及时性,支持更多的同时在线人数?"等几个问题给出了实现层面的解答。 在本课题给出的服务器集群中,整个游戏服务按功能被分解为游戏世界整体控制、玩家登陆验证、游戏逻辑过程处理和数据存取等不同的部分,这些部分的工作由中央控制服务器、登陆验证服务器、游戏逻辑服务器和数据库服务器分别负责。由于使用了中央控制服务器作为一个信息的集成和中转中心,本服务器构架具有较好的可扩展性,可以在此基础上将其扩展为能够胜任商业化的运营的服务器集群。虽然本文给出的只是游戏服务器集群的一个实现方案,距离商业运营所需达到的要求还有一定的距离,但测试数据说明该方案是可行的,为今后商业运营软件的开发打好了基础。
