Then , it analyzed can and canopen application layer , including : real - time characteristics of can , the core of canopen - od , all kinds of communication objects , the allocation of cob - id and some device profiles . and xcanopen was brought forward for implementing of canopen in power line communication . then , on the reference design platform of freescale - agilent , xcanopen ’ s two standard software interfaces , bottom driver and function of communication and network management based on canopen were implemented 本文详细分析了低压电力线通信调制解调器的结构与工作原理;分析了can协议及其可以保证数据实时可靠传输的实质,剖析了应用层协议canopen ,着重解释了canopen的核心?对象字典od 、各类通讯对象、标识符的分配,以及一些设备子协议( deviceprofiles ) ,并提出了在电力线通信上实现canopen的解决方案? xcanopen框架;在基于freescale - agilent电力线通信的参考设计平台上实现了xcanopen的两个标准软件接口,电力线通信底层驱动软件的设计以及基于canopen协议栈的节点通信和网络管理功能,达到了使用canopen协议来实现电力线通信的标准化模块的目的;最后,在canopen数据通信的实时调度上做了进一步的改进探索研究。
This paper first makes detailed study on the architecture and software components of the pld - logical decrypting system , and the hardware construction of the isa bust interface card , then presents the hardware design of the pci bus interface card , and the dos software interface with the pld - logical decrypting system for the smooth conversion from isa to pci 在此基础上给出了基于pci总线的接口板的硬件设计和在dos下的与原系统的软件接口，完成了接口板从isa总线向pci总线的移植，实现了新接口板与原系统的无缝连接。
This technology is to write the data or program , which can determine if the software is legal or not , into the storage of the hardware lock in advance , and then determine the users legality by reading the original saved data through a software interface program to achieve the goal of software protection 这种保护技术是将确认是否为合法软件的数据或程序，先行写入硬件锁的储存体内，然后透过软件接口程序，在程序执行中将原先储存的数据读出以判别使用者的合法性，达到软件保护的目的。
Because of its advantage , such as its simplicity of its implementation , easiness to understand , convenience to access to the finite element application software etc . , it has been generally applied by the engineering circle , and is thought of , by babuska etc . , as one of the most robust posterior error estimators which are asymptotically exact 由于它具有计算简单、易于理解、和现有的有限元应用软件接口方便等特点，因此受到了工程界的广泛欢迎，并被babuska等人认为是用于渐进准确的后验估计效果最好的技术之一。
The evolution of the protection lock , as mentioned above , is partial to the constant innovation of hardware ; as is the development of the software interface . due to the rise of the pc lan local area network drive - an upsurge of networking applications development , it brings software design companies that are used to developed dos version software , running to change their direction toward the developed networking software 前面所提及的保护锁演进过程，偏向于硬件上的不断创新部份至于软件接口上的发展，由于pc lan local area network的兴起，带动应用程序网络版的开发热潮，以前开发dos版本的软件设计开发公司，纷纷朝向开发网络版软件的方向前进。
Combining vi technology , quality inspection , quality controlling and instrument management , and bringing forward a mean that integrating virtual inspection , instrument dynamic management , inspection process dynamic management , quality controlling and instrument . adopting popular database technology and software interface of relational database and integrating inspection environment , establishing virtual inspection instrument software module database , and to develop function of recording , saving , deleting , adding , editing , searching and so on for developed virtual inspection instrument module 将技术与质量检测、质量控制和仪器管理相融合，提出了虚拟测试与仪器信息管理、测试过程管理、质量控制等管理功能的集成方法；采用流行的关系数据库技术，以及关系数据库与集成测试环境的软件接口，建立虚拟测量仪器软件模块数据库，进行所有已开发好的虚拟测量仪器软件模块的记录、存储、删除、添加、编辑、检索等功能。
The software interface program shall be designed with a loadable module under the client server architecture . take novell s nlm netware loadable module model that is provided by netware network operating system for example ; due to its software interface that was designed with a loadable module , the resources of other work stations can not be occupied , so that is to enable the best performance 这个软件界面程序，在主从架构client server下，必须以可加载模块loadable module方式来设计的，例如： novell公司所出版的netware网络操作系统提供的nlm netware loadable modiule模式，因为以加载模块的方式来设计的软件接口，可以不占用其它工作站的资源，使得执行效率达到最佳化。
