汽车智能检测自救报警系统优化设计
<p>汽车是人们现代生活中重要的交通工具,人们在追求汽车带来的经济、便利、高效的同时往往会忽略汽车中所存在的安全隐患,为此,本文结合威驰车的实际状况对智能自救报警装置控制系统进行优化,该装置通过STC89C51单片机进行信号检测与控制,可以判断车内环境是否安全,能够及时报警并降车窗,通过通讯模块发送短信并拨打求救电话完成自救,保证车内人身安全。</p><p>In people's mode
基于CANbus的OBD系统研究与设计
<p>随着汽车产业技术的发展，出行便捷的同时亦有许多负面影响，增强汽车性能，更加精确合理的监控及诊断技术亟待解决，另外，车辆内部的电子部件日趋增多，总线上传输信息的载体也由多路线束被现场总线所取代，基于CAN</p><p>（Control Area Network）总线机制，本课题提出新的报文传输方式，节点内部差别服务模型，完善的诊断系统，2008年7月1日，我国内生产的所有乘用车必须采用OBD
基于ARMLinux的多道脉冲幅度分析器数字系统设计
随着电子技术的不断发展，各种智能核仪器逐步走向自动化、智能化、数字化和便携式的方向发展。针对传统的多道脉冲幅度分析器体积大，人机交互不友好，不方便现场分析等的缺陷[5]。新型的高速、集成度高、界面友好的多道脉冲幅度分析器的陆续出现填补了这一缺点。 随着电子技术的发展，以ARM为核的处理器技术的应用领域不断扩大，相比较单片机而言，它的主频高、运算速度快，可以满足多道脉冲幅度分析器的苛刻的时间上的要求
基于ARM的PDF417二维条码识别
条码技术是随通信技术，计算机技术的发展应运而生的自动识别技术的一种。根据二进制编码规则对应形成的由对光反映率不同的条、空组成的图形，经光电扫描识读器扫描，将采集的信息经处理器进行处理，从而达到自动识别的目的。条码技术自出现以来，得到了人们的普遍关注，发展十分迅速，已广泛用于交通运输、商业、医疗卫生、制造业、仓储业、邮电业等领域，极大的提高了数据采集和信息处理的速度，提高了工作效率，并为管理的科学化

ARDUINO技术内幕
《arduino技术内幕》摒弃了大量基础知识，全面深入揭秘arduino 的内部工作原理。其中，它通过“led 闪灯”、“led照明”、“数字钟”等示例作品由浅入深、由易而难介绍arduino 开发，并最后以一个“自动机器人”示例总结全书，不仅介绍了可用的软硬件及软硬件间的协作，阐述了软硬件的选取与设计，而且分析了项目管理（包括文档化、团队工作与协作开发以及如何选择许可方式）方面的内容。另外，读者
ROS探索总结
<p>ROS系统是起源于2007年斯坦福大学人工智能实验室的项目与机器人技术公司Willow Garage的个人机器人项目（Personal Robots Program）之间的合作，2008年之后就由Willow Garage来进行推动。已经有四年多的时间了 (视频)。随着PR2那些不可思议的表现，譬如叠衣服，插插座，做早饭，ROS也得到越来越多的关注。Willow Garage公司也表示希望借
基于RS485的监护和输液诊疗一体化系统——注射泵
<p>对危重病人的监护和输液治疗，是全球范围内的医护人员关注的重大问题。危重病人的生理状态极不稳定，医护人员需要根据患者生理状态，给予迅速准确的治疗。在无线网的ICU诊疗一体化系统的基础上，拟研制的基于RS485的监护和输液诊疗一体化系统(简称诊疗一体化系统)，形成无线有线两大系列的产品。该系统由输液设备(包括注射泵、输液泵)，监护输液基站(平板电脑)、医护PDA(Personal Digital
