【摘要】 智能高速球形摄像机是视频监控系统中一种重要的前端设备,它集模拟视频采集、云台控制、镜头控制和远端通讯等功能于一体。最大限度地减少了系统部件之间的连接和安装过程,提高了监控系统的可靠性、稳定性。本论文的主要工作是以LPC2132 ARM微控制器为核心,完成高速智能球机软硬件的设计与实现,开发出一款性价比具有竞争力的智能高速球机,以满足市场需求。其具体内容包括:根据对市场上现有的高速球的性能、价格等方面的调研,确立本款球机需要具备的功能和要达到的技术指标。并据此确定球机在硬件方面和软件方面的总体设计方案。硬件方面,主要是结合球机外形结构确立硬件各电路板的尺寸大小、选择核心处理器及各功能模块的应用芯片,最后完成电路设计、样板的制作和调试。软件方面,完成了各芯片的底层驱动程序的设计,以及完成包括电机控制模块、字符叠加模块、机芯控制模块、数据存储模块等控制模块的应用程序开发和测试。本次成功开发的NCC-628A型智能高速球型摄像机通过严格的测试,运行可靠稳定、预置位准确无误。目前已经量产并投入市场,在安防工程应用中也获得了良好的预期效果。最后针对此次项目开发中的关键技术进行了分析,并提出了改进的方法。更多还原

【Abstract】 Intelligent high-speed ball machine is one kind of the important Front-End equipments in the video surveillance system, which is a combination of analog video capture, PTZ control, lens control and remote communications. It helps users to reduce complex connection of the system components to the maximum extent and simplify the process of installation. So it can improve the reliability and stability of the monitoring system. With the core of the LPC-2132 ARM Microcomputer, the major tasks of the thesis designs and accomplishes the hardware and software system of the intelligent high-speed ball, successfully develop one kind intelligent high-speed ball machine, which enjoys the best price versus performance ratio and meets the market demand. The specific works including:According to the survey of the performance and price about intelligent high-speed ball in the current market, determine what function the ball should have and technology indicators it must reach. Then plan the overall design program about the hardware and software.The major task of hardware design includes determining the size of all circuit boards according to the shape and structure of the ball, choosing the core processor of the system and dedicated chips for the different function modules, and finishing circuit design, boards proofing and debugging.The major task of software design includes writing all drivers for the dedicated chips, and programming and debugging for all function control modules which include motor control module, character superimposition module, lens control module, data storing module and so on.The successfully developed intelligent high-speed ball machine which is named NCC-628A passed through rigorous testing, run highly reliable and stable and the preset positions are accurate. At present, this product has been sold well in market and achieved the desired result in the engineering applications. Finally, the thesis analyzes the key technologies in this project development, and presents improved methods for further research.更多还原
