The media control interface ( mci ) provides standard commands for playing multimedia devices and recording multimedia resource files . these commands are a generic interface to nearly every kind of multimedia device 媒体控制接口( mci )提供了播放多媒体设备以及录制多媒体资源文件的标准命令集合。此集合中的命令几乎可以作为任何一种多媒体设备的通用接口。
With a touchscreen , a linux device can become a controller for a slew of devices such as a digital video recorder , a tivo - like personal video recorder , a media center , a smart - house system , or even a control interface to a toaster 使用触摸屏, linux程序就可以成为很多设备的控制器,例如数字录像机、类似tivo的个人录像机、媒体中心、智能房屋系统或者烤面包机的控制界面。
A touchscreen facade can make back - end linux applications very usable in such devices as custom digital media centers either in the home or in automobiles , dvrs and pvrs , and even control interfaces for household robots 前端触摸屏可以让后台的linux应用程序在多种设备中非常有用,例如定制的数字媒体中心(可以是家里,也可以是汽车中) 、 dvr 、 pvr甚至是家用机器人所使用的控制界面。
However , even recently , these are not many excellent solutions . it is because that network designers have left few control interfaces in the lower layer of the network , and network users have strong unwillingness to make major changes on the accustomed protocols 而在上层网络,人们虽然一直致力于研究应用层的服务质量保证及其相关的协议问题,但这些大多只是为了个别的业务类型和用户服务,对整体的网络性能贡献有限。
Based on the self - industry and the application of the other trade on auto - control technique , this paper advances the frame of the control and management system - beer - pack2000 , develops supervisory control interfaces for beer - filled process , and designs the control system by omron for opening value , inspecting and brushing the broken bottle . at last , this paper advances the thought of controlling the liquid and press in storing tank by pid , simulates and lines up the parameter by simulation software - matlab 在windows98环境下,用组态王软件开发了啤酒灌装生产线的监控界面,用组态王内部提供的仿真plc实现了动画连接;并用日本omron系列可编程控制器设计了阀开启、破瓶检测、破瓶冲洗、自动落盖等过程的自动控制;最后提出了用控制方面较为成熟的pid算法来控制全自动灌装压盖机贮液缸内液位和压力的想法,并用仿真软件matlab的动态仿真环境simulink对其参数进行了仿真整定。
