基于GPRS和GPS的汽车防盗系统设计

　　随着中国经济的迅猛发展，购车的家庭越来越多，但随之而来的是盗车案件的增加。虽然目前大多数车辆都装有防盗系统，但一般为声光警告，一旦人与车距离过远，车主将不能及时得知车辆被盗消息，因而失去很多报警的机会。如果车主有一部收发短消息的GSM手机，防盗系统就可以实现实时报警，并且GPS可确定具体车辆的方位信息，便于查找丢失的汽车。 1 核心控制器部分 1.1 STR710F微控制器介绍 ...[详细]

如何选择电源

由于电子产品的风靡，能够用多种电源供电的设备已经屡见不鲜了。例如，工业手持式仪表或便携式医疗诊断设备大部分时间用电池供电，但一旦插入交流适配器或 USB 端口，就从交流适配器或 USB 端口吸取功率了，这时既为电池充电，又为系统供电。在移动系统的另一端，大型高可用性服务器机架内至少有两个电源，以在任何一个电源出故障时，保持服务器正常运行。存储服务器则用超级电容器作备份电源，以在主电源断开时，...[详细]

出海是指中国以移动互联网、人工智能、共享经济等新技术和新商业模式向海外拓展的行为，其本质是新兴技术产业的出口。品途商业评论关于2017亚太区域互联网创新创业高峰论坛的报道中指出，从中国AI科技企业的融资、团队和发展规模来看，在全球范围内已经具备了一定的竞争力；随着中国政府一带一路的政策加持，中国AI科技创新领域的优秀企业已经在其他国家和地区崭露头角。人工智能如今已是遍地开花，如何在泡沫中寻找明晰...[详细]
如何拦截损坏你的示波器三大“杀手”？

你的示波器是否健康，多长时间进行一次体检？来自泰克对全球500位工程师使用示波器的习惯与维护方法调查表明，85%的工程师一年进行一次示波器校准，72%的工程师会定期检查及保养示波器，67%的工程师明确了解其使用的环境及要求，65%的工程师明确了解其测试的要求。认识三大杀手所有测试仪器故障中，硬件问题只占不到一成，更多的是由于仪器缺少定期的点检、保养和示波器的使用不当导致性能差异，需要进行...[详细]
爱立信消费者报告：个人安全推动可穿戴设备市场超越医疗保健市场

微软可能推Surface mini：最好用WP操作系统

TechCrunch今天发表评论文章，谈及Surface mini，如果微软当真推出小屏幕Surface，可能会刺激Windows Phone 8的发展。文章如下：我喜欢Surface的理念：有吸引力的硬件，Pro外壳不错，它还作出明智的妥协，以提供好的价值。但产品本身没有达到预期的承诺。它有着第一产品的缺陷。不过，如果微软推出低价Surface，它配有更小的显示屏，产品可能会让S...[详细]
网联自动驾驶车辆通过信号交叉口的速度轨迹优化方案

文章摘要以网联自动驾驶汽车（Connected Autonomous Vehicle，CAV）为研究对象，研究了CAV车队通过城市信号交叉口的速度轨迹优化控制策略。基于最优控制理论，采用CAV的自动驾驶模型描述车间相互作用，以所有CAV车辆在行驶过程中的总油耗为优化目标，根据信号灯的配时信息建立模型约束，通过优化CAV头车的速度轨迹，保证整个CAV车队在绿灯相位下快速通过交叉口并实现油耗最小。...[详细]
