1996 年原电力工业部颁发了《电力负荷控制系统数据传输规约（试行）–1996》（以下简称“96 版规约”），经过八年多的实际运用，为电力负荷管理系统的建设、运行和发展奠定了良好的基础，同时， 随着大量应用系统的不断完善和发展，96 版规约本身也在这些实际系统的应用中得到了不同程度的丰 富和扩展。电力负荷管理系统已成为电力需求侧管理、电力营销与客户服务工作的重要组成部分，为适 应系统发展的需求变化，保证系统建设具有良好的规范性、兼容性、开放性和扩展性，有必要对96 版 规约进行修订。 本次规约修订是在96 版规约的基础上，依据《电力负荷管理系统功能规范》和《电力负荷管理系 统通用技术条件》的要求，并结合目前实际、今后技术和应用发展的需求。修订过程中多次召集科研、 用户和生产单位中的有丰富实践经验的专家参与讨论，广泛征求意见。 本规约遵从GB/T18657（等同IEC60870-5）推荐的传输规约模式，采用三层增强型结构，适用于 平衡式和非平衡式等通信网络。-1996 original Ministry of Power Industry issued a "power load control system data transmission protocol (Tentative) -19 96 "(hereinafter referred to as" 96 edition of the Statute "), after more than eight years of actual use for the electric load management system, the operation and development has laid a good foundation for the same time, with a large number of applications of continuous improvement and development, 96 version of the Statute itself is the practical application of the system were different degrees of wealth and expansion. Power load management systems have become DSM, power marketing and customer service an important part of for the system to adapt to the changing needs of development, building systems to ensure a good standard, compatibility, open and 下载

Windows CE是微软为嵌入式设备打造的操作系统，而嵌入式设备可谓多种多样，这就要求CE操作系统必须是可定制的，所以微软将Windows CE设计为模块化的操作系统。说简单点，我们可以把Windows CE想像成一盒积木，你可以用积木搭建出任何物体，但不一定要把所有的积木都用上 -Microsoft Windows CE for embedded devices to create the operating system, which has many embedded devices, which requires CE operating system can be customized, so Microsoft Windows CE for the modular design of the operating system. That simple point, we can imagine Windows CE into a box of building blocks, you can use the modular structures any objects, but not necessarily to put all the building blocks are used 下载

CPU是计算机系统中一个十分重要的资源，本章主要介绍处理机的调度目标、策略以及评价方法等。因为处理机调度程序不可能选择全部驻留在外存的进程，因此，在调度一个进程占有处理机之前，系统必须按某种策略把外存中处于后备状态的作业选择出来，并创建进程和分配内存，为进程执行准备必需的资源。这一步称为作业调度或高级调度。作业调度的目标是尽量做到公平合理，能执行尽可能多的作业、尽快地响应时间以及高的设备利用率等。任一调度算法要同时满足这些调度目标是不可能的。大多数操作系统都是根据用户需要而采用兼顾某些目标的方法。比较常用的作业调度算法有：FCFS（先来先服务）、方法、SJP(最短作业优先)法、HRN(最高响应比)法等。这-CPU computer systems is a very important resource, this chapter introduces processor scheduling objectives, strategies and evaluation methods. Because the processor scheduling procedures could not choose Disk presence in all the process, and therefore, in the process of scheduling a possession before the processor, the system must be some kind of strategy to Disk backup were at the operational state of choice out and the process of creation and distribution of memory, the process of preparing the implementation of the necessary resources. This step as job scheduling or senior scheduling. Job Scheduling goal is to try to make it fair and reasonable to carry out the operation as much as possible, as soon as possible to response time and high efficiency in the use of equipment.

本系统采用access+asp开发，系统要求：windows9X+pws win2000(或更高)+IIS、IE 4.0以上及相关打印设备 2、处于安全考虑,建议安装使用前，先修改数据库路径(默认为"tcadmin\tcmdb")及数据库名称,然后修改文件tcconn.asp相应路径设置 3、本系统所有日期格式均为:yyyy-mm-dd,例如:2004-03-28.请按此格式输入日期,否则日期数据拒绝存入数据库 4、档案输出文件为word(*.doc)格式。由于个人配置及环境不一，所以输出后建议用MS word稍作编辑 5、系统所有查找定位均支持模糊查找。例：输入关键词："李"，选择条件按 "姓名" 查找，则记录列表将显示所有姓名中含有"李"字的教师记录 6、教师业务档案输出时，建议先保存后编辑，以免给你造成不必要的麻烦 7、教师查询页面学院首页指向：tcadmin/user_search.asp 8、教师业务档案管理系统登陆页面学院首页调用：login.htm ,调用方法：首页插入代码：<iframe src="你的路径/tcadmin/login.htm" scrolling="no" frameborder="0"></ifram-access the system using asp development, system requirements : windows9X pws WIN2000 (or higher) IIS, IE 4.0 and related printing equipment, in safety considerations, the proposed installation, modify the database path first (default "tcadmin \ tcmdb") and the database name, then amend the document tcconn.asp corresponding set up three paths, all of the system date formats are : yyyy-mm-dd, for example :2004-03-28.

安装完成后，必须对系统所使用的后台数据库进行配置才可以正常使用。 在主程序目录内建立名为data的子目录存放改系统数据库文件，为了方便程序调用，要在Dalphi的BDE管理窗口中建立“SPXSGL”的数据库别名，如图2所示，目录位置为“…\商品销售管理系统\data”。后台数据库建立好以后，就可以根据各个模块的功能，设计窗口和编写代码了。 -installation is complete, the system must be used in the background configuration database can use. The main program directory within the subdirectory called data storage systems, database files change, in order to facilitate the procedure call, in the BDE Dalphi management window to establish "SPXSGL" database alias. As shown in figure 2, directory location for "... \ sales management system \ data." A good background database, can be based on the function of each module, window design and preparation of the code. 下载

这就是陈建春的《用Visual C++开发GIS系统》的配套代码。 用来给初学者熟悉VC++图形编程很不错，我当初学MFC的时候就是照着这本书上手的。但作为一个GIS系统来说缺少一些必要的 要素，比如大数据量的管理、空间索引、符号化、投影等等等等等。以现在的眼光看来整个系统的架构设计也不是太好。 这本书再版后改名为《矢量图形系统开发与编程》，内容变化不大-"using Visual C development of GIS systems" supporting code. For beginners to the VC familiar with graphical programming quite well, and I had the time to learn MFC is shining on this book in the business. But as a GIS systems lack the necessary elements, such as the large amount of data management, spatial indexing, symbols, such as projectors, etc.. Now the point of view of the entire system architecture design is not too good. This book reprinted later renamed as "vector graphics systems development and programming", little change 下载
