Embedded systems span all aspects of modern life and there are many examples of their use. Telecommunications systems employ numerous embedded systems from telephone switches for the network to mobile phones at the end-user. Computer networking uses dedicated routers and network bridges to route data. 8.4嵌入式系统的应用嵌入式系统应用于现代生活的各个领域,生活中使用嵌入式系统的例子很多。从网络电话交换机到最终用户的移动电话,通信系统使用了多个嵌入式系统。计算机网络使用专用路由器和网桥进行数据发送。
Consumer electronics include personal digital assistants(PDAs),mp3players,mobilephones,videogame consoles,digitalcameras,DVDplayers,GPSreceivers,and printers. Many household appliances,such as microwave ovens,washing machines and dishwashers,are including embedded systems to provide flexibility,efficiency and features. Advanced HVACsystems use networked thermostats to more accurately and efficiently control temperature that can change by time of day and season.消费类电子产品包括个人数字助理(PDA)、MP3播放器、移动电话、游戏机、数码相机、DVD播放器、全球定位系统接收器和打印机。许多家用电器,如微波炉、洗衣机和洗碗机,采用嵌入式系统,保证了灵活性、效率和功能。先进的空调系统使用网络自动调温器,以便更准确、更有效地控制温度随时间和季节而变化。

嵌入式系统产品示例
[1]Home automation uses wired-and wireless-networking that can be used to control lights,climate,security,audio/visual,surveillance,etc.,all of which use embedded devices for sensing and controlling.家庭自动化使用能够控制灯光、气候、安全、音频/视频、监视等的有线和无线网络,所有网络都使用嵌入式设备进行传感和控制。分析:在定语从句中的allofwhich中,ofwhich作定语从句主语all的定语which指代wired-and wireless-networking。在“介词+关系代词”引导的定语从句中,“介词+关系代词”前可有some,any,none,both,all,neither,most,each,few等代词或者数词作定语从句的主语。例如:Hehasalotof story-books,a few of which Ihavenever read.他有很多故事书有几本我还从未读过。
从飞机到汽车,运输行业越来越多地使用嵌入式系统。新飞机载有先进的航空电子设备,如惯性制导系统和全球定位系统接收器,这些设备都有相当高的安全要求。各种电机——无刷直流电机、感应电机和直流电动机——使用的是电气/电子马达控制器。汽车、电动车和混合动力车越来越多地使用嵌入式系统,以最大限度地提高效率和减少污染。Transportation systems from flight to automobiles increasingly use embedded systems. Newairplanes contain advanced avionics such as inertial guidance systems and GPSreceivers that also have considerable safety requirements. Various electric motors—brushless DCmotors,induction motors and DCmotors—areusingelectric/electronic motor controllers. Automobiles,electricvehicles,and hybrid vehicles are increasingly using embedded systems to maximize efficiency and reduce pollution.
医学上更多地使用监测生命体征的嵌入式系统、放大声音的电子听诊器、以及用于非侵入性内部检查的各种医疗成像技术(PET、SPECT、CT、MRI),医疗设备随之不断改进。Medical equipment is continuing to advance with more embedded systems for vital signs monitoring,electronic stethoscopes for amplifying sounds,and various medical imaging(PET,SPECT,CT,MRI)for non-invasive internal inspections.
[2]In addition to commonly described embedded systems based on small computers,a new class of miniature wireless devices called motes are quickly gaining popularity as the field of wireless sensor networking rises.分析:句中as the field of wireless sensor networking rises为as引导的时间状语从句。as引导的时间状语从句,往往表示主句动作发生的背景或条件,常常翻译成“随着……”之意。例如:Asthetimewenton,the weather got worse.随着时间的推移,气候更加糟糕。译文:除了经常描述的基于小电脑的嵌入式系统,一类称为motes(微尘)的新微型无线装置正随着无线传感器网络领域的发展而迅速日益普及。
Wireless sensor networking,WSN,makes use of miniaturization made possible by advanced ICdesignto couple full wireless subsystems to sophisticated sensor,enabling people and companies to measure a myriad of things in the physical world and act on this information through IT monitoring and control systems. Thesemotes are completely self contained,and will typically runoff a battery source for many years before the batteries need to be changed or charged.无线传感器网络(WSN)利用先进的IC设计所带来的小型化,把完整的无线子系统与先进的传感器结合,使人们和公司能在现实世界中进行许多测量,并基于测量信息通过监测和控制系统而采取行动。这些motes完全自我控制,通常可以使用很多年才需要更换电池或充电。
