风光互补路灯设计方案，包含系统设计，硬件成本，发电效果(Scenery complementary lights design, including system design, the hardware cost, the effect of power generation)

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)

本文介绍了一种采用Altera 公司的FFT MegaCore 实现快速傅里叶变换的方法，该方法非常简单，能进一层次简化开发的流程，缩短工程开发周期，节约成本，因此在实际工程中是一种很好的应用。(This paper describes a use of Altera s FFT MegaCore fast Fourier transform method, the method is very simple and can develop into a hierarchy to simplify processes, shorten the project development cycle, cost savings, and therefore is a practical engineering good application.)

介绍了一种基于低成本CMOS摄像头的智能监控系统,实现了现场监控的实时化、智能化。系统可自动判别危险程度,可分别提供绿色、黄色和红色报警信息,并驱动相关附属设备工作。针对图像传输过程中的噪声,系统采用了对噪声图像使用局部算子的滤波技术来提高图像质量。根据对静态图像进行三原色分离后误差域的研究,达到背景与图像分离的目的,成功实现了图像的获取和处理。在低成本投入下,以简单的配置和简便的操作达到了高性能监控系统的功能。(Introduce a low-cost CMOS camera-based intelligent monitoring system, realize the scene in real-time monitoring and intelligent. The system can automatically determine the degree of risk, they can provide green, yellow and red alarm information, and drive the work-related ancillary equipment. For image transmission in the process of noise, system noise images of the use of local filtering operator technology to improve image quality. Based on static images RGB domain after the separation error research, background and images to achieve the purpose of separation, the successful implementation of the image acquisition and processing. Input in the low-cost, simple configuration and easy to operate to achieve a high-performance monitoring system.)
