Therefore, there is a possibility for improving the performance of non-real-time data traffic while still meeting the QoS of service requirement for real-time CBR traffic. The DOCSIS is established as the primary HFC network data communication standard. The intended service allows transparent bi-directional transfer of Internet Protocol traffic between the Cable Modem Termination System in cable system headend and Cable Modem in customer locations with significantly high data rate.

DOCSIS HFC网络的宽带性能使得传输高质量的实时音视频数据成为可能，实时可变比特率视频业务是宽带HFC网络的主要应用之一，实时VBR视频业务具有严格的延时和延时抖动要求，然而当前的DOCSIS HFC网络只能提供高速Internet接入，只支持有限的服务质量保证，现有的协议和方法不适合上行传输实时VBR视频业务。

Therefore, it is necessary to research the communication protocol for M-bus before commencing bus interface.

论文首先研究了METER-BUS的通信协议。

PC and MCU are popularly used in the field of remote control and measurement with the method of direct use of PC or embeding the MCU chip in the system Because of the different requirement and condition ,the system usually can not be used universally thus people usually have to develop the system in according to the specific requisite The article mainly introduced the software design of the control system and simply introduced the whole system design include hardware, communication protocol. The software has the following features:? Fulfill the object of encapsuling all of the device and instrument by the way of using a abstract class of C++, thus the whole system can be easily expanded .

在远距离测控技术领域，微机技术得到了广泛的应用，包括在系统中使用微机或者嵌入微处理器芯片，而实时测控系统由于使用的要求和环境各不相同，因而通用性不是很好，本文以为某单位研制的具有特殊要求的一种远程测控系统为背景，着重介绍了该系统的测控软件的研制，由于软件是和系统中其他部分相配合的，为方便理解，简要的介绍了全系统的研制工作，本软件具有如下特点：·实现了将测控系统的所有被控制设备和测量仪器封装，用抽象的一个C++对象来表征具体的物理设备。
