中频感应加热以其加热效率高、速度快,可控性好及易于实现机械化、自动化等优点,已在熔炼、铸造、弯管、热锻、焊接和表面热处理等行业得到广泛的应用。
本设计根据设计任务进行了方案设计,设计了相应的硬件电路,研制了20KW中频感应加热电源。
本设计中感应加热电源采用IGBT作为开关器件,可工作在10 Hz~10 kHz频段。它由整流器、滤波器、和逆变器组成。整流器采用不可控三相全桥式整流电路。滤波器采用两个电解电容和一个电感组成Ⅱ型滤波器滤波和无源功率因数校正。逆变器主要由PWM控制器SG3525A控制四个IGBT的开通和关断,实现DC-AC的转换。
设计中采用的芯片主要是PWM控制器SG3525A和光耦合驱动电路HCPL-316J。设计过程中程充分利用了SG3525A的控制性能,具有宽的可调工作频率,死区时间可调,具有输入欠电压锁定功能和双路输出电流。由于HCPL-316J具有快的开关速度(500ns),光隔离,故障状态反馈,可配置自动复位、自动关闭等功能,所以选择其作为IGBT的驱动。
对原理样机的调试结果表明,所完成的设计实现了设计任务规定的基本功能。此外,为了满足不同器件对功率需要的要求,设计了功率可调。这部分超出了设计任务书规定的任务。(induction heating with high heating efficiency, speed and good controllability and easy to mechanization. the advantages of automation, in melting, casting, bending, forging, welding and surface heat treatment and other industries have been widely employed. According to the design tasks for the design of the program design, design corresponding to the hardware circuit, Development of 20 KW induction heating power. The design of induction heating power IGBT used as a switching device, which can work in 10 Hz- 10 kHz frequency band. It consists of rectifier, filter, and the inverter components. Controlled Rectifier not use the entire three-phase bridge rectifier circuit. 2 filter used an electrolytic capacitor and inductor components II-type filter and passive PFC.

VideoMonitorSystem
基于网络的视频监控系统
随着时代的发展,人们对安全防范也越来越重视,而数字化视频监控系统在音视频录像、报警录像联动、硬盘存储、多画面显示等方面都有突出表现,因此在安防领域逐渐占有了一席之地。本文提出的基于网络的视频监控系统实现了对数字硬盘录像机的控制功能,其远程客户端软件可以同时播放四路具有高达Dl分辨率的图像数据。
第一章论述了视频监控系统和数据压缩技术的发展动态。
第二章对客户端软件的开发环境及平台进行了选择,并就其中使用的关键技术:windows sockets编程技术、windows多线程技术、windows图像显示技术、MPEG-4编解码与数据传术技术、流媒体技术做了简介。
第三章详细论述了客户端软件的设计及实现。包括客户端软件的整体设计和各模块的设计实现,最后给出了实现结果。
第四章是论述了实时流媒体播放器的设计和实现,包括主要模块设计实现 (网络接收模块、解码模块、显示模块、操作控制模块)、其他模块设计实现(显卡能力探测模块、表面管理模块)、性能优化(缓冲、共享内存、线程模型)。
第五章对系统进行了总结,并为系统进一步发展提出了展望和规划。
