[系统设计方案] Design-of-A-Concentrator
集中器是抄表系统重要的组成部分，其性能好坏直接影响到抄表系统工作效率。本文利用先进的嵌入式技术设计并实现了一种电能抄表集中器，具有运行速度快、功能强等特点，既可以通过以太网应用在局域网覆盖的小区．也可以通过GPRS对没有宽带接入的小区或偏远的农村进行用电管理。该集中器经过适当的调整，可以应用于供水、供气系统中，做到水、电、气三表合一的集中抄表。
Concentrator,as an important component of the metering system,whether performances well will directly affect the eficiency of the metering system．This paper introduced the design of an electric energy metering concentrator by adopting the advanced embedded system technology．Th e electric energy metering concentrator offers the desirable features of high speed and strong function,etc．Furtherm ore，it not only can be applied in the districts covered of the L N through the Ethemet,but also can be applied in the districts or remote rural areas where there is no broadband accessing through the GPRS．With appropriate adjustments，the concentrator can be used in water supply systems and gas supply systems．It can provide the function of reading the degrees of water，electricity and gas in the same meter． (2011-10-16, Unix_Linux, 172KB, 下载54次)
[系统设计方案] UNIX
随着IT网络规模和复杂性不断增加,对网络进行有效管理,保证网络的运行质量,变得越来越重要。主机管理是IT网管中不可忽视的一部分,一般情况下人们都采用SNMP来获得设备主机的相关信息。但是对UNIX主机而言,并非所有的设备信息都能通过SNMP来取得,因为SNMP中的一些变量是不可访问的,而且另有一些需要管理的设备信息SNMP不提供支持。 本文设计并实现了一套独立于SNMP的UNIX主机信息采集系统,对自适应高可扩展主机管理信息采集机制进行了研究,并对以下关键技术问题给出了解决方法: 1)负载自适应插件式的Agent:一套负载自适应插件式的基于命令结果语义解析的Agent机制。该机制完成主机性能数据采集,具有良好的可扩展性,并能调节采集周期以适应主机负载情况。 2)通用语义解析框架:定义用于描述管理指标解析的通用解析原语及运算规则,设计了通用解析引擎,该引擎以主机端部署Agent上报的源文件作为输入,通过分析解析原语并进行运算,得到所需的管理指标值。
Along with the increasing scale and complicacy of the network,, it s important to manage the network effectively and keep the running quality of the network. Mainframe management is an important part of IP network management, generally speaking, SNMP is the main method to collect mainframe information. But for UNIX mainframe, SNMP could not get the whole information we need, because some of them are not supported by SNMP. (2011-09-09, Unix_Linux, 3386KB, 下载3次)

本计划之目的在于开发一开放源码之具有GUI 接口之嵌入式网路 行 动通讯装置。将发展潜力 雄厚由Google开发之网路 通讯软件GoogleTalk 整合移植于一嵌入式开发板上，再外加一无线网卡时，此系统即成为网路 行 动通讯装置(network mobile communication device)。Googletalk 为一功能强大之通讯软件具有简讯、语音、影像、档案传送等网路 通讯功能，并具有多方通讯(conferencing)之功能，且其账号之取得与通话费用完全免费，只需注册为Gmail 之用户即可，相信在此方便 性与google 之强力 推广下，其用户數 有朝一日将可与Skype 分庭抗禮 。本计划使用Intel Xscale PXA270做为硬件开发平台，以embedded linux为操作系统核心，移植Google所释出的libjingle，配合USB无线网卡来实现无线嵌入式 GoogleTalk。
The purpose of this project is to develop an open source it has a GUI interface to the embedded network mobile communication devices. Strong development potential will be developed by the Google GoogleTalk integration of network communication software, embedded development board in a transplant, and then plus a wireless network card, this system is a network mobile communication devices (network mobile communication device). Googletalk of a powerful communications software with SMS, voice, video, file transfer and other network communication, and communication with the multi-(conferencing) function, and the account of the cost of acquisition and the call is free, just sign up for the Gmail of users can, I believe that in this convenience of the strong force with the promotion of google, its users and Skype numbers will one day be the Chamber of anti Ceremony. The plan to use the Intel Xscale PXA270 as hardware development platform for the embedded linux operating system kernel, release (2011-05-09, Unix_Linux, 7532KB, 下载7次)
