系统信息

The emerging interest of research into multi-sensor information theory is viewed as timely since the multiformity, massiness, complex and real-time processing of information in multi-sensor system has gone beyond the human brain capacity of processing information.

多传感器系统中，信息表现形式的多样性、信息数量的巨大性、信息关系的复杂性以及要求信息处理的及时性，都大大超出了人脑的信息综合处理能力，多传感器信息融合理论应运而生。

The system is designed according to the mechanism of CAD Standard Part Graphies Files. SQL Server 2000 is selected as the host and construct the database of part liabrary due to characteristic parameter. STEP, viz. ISO 10303, is issued by international standardization organization, and here ,this paper gives the definition of product information model oriented part41 and part44 in STEP and six basic definienses which describe the product information to ensure the information in the product information model correct and shareable . This paper also presents method of creating and extracting product information on engineering draught and product data exchange and integration between CAD system and database manager system.

论文中采用&CAD标准件图形文件机制&，用SQL Server2000数据库建立了零件的特征参数数据库，完成了零件库的特性参数库建库工作；依据国际标准化组织的STEP标准即ISO 10303中的Part41，Part44两部分内容以及STEP标准中描述产品信息的六个基本的类库定义，提出了一种产品信息模型，保证了产品信息模型中信息的正确性和共享性，实现了工程图样中产品管理信息的建立和提取以及数据库系统与图形文件中的管理信息交换与集成。

The first idea to deal with the packet loss is the new proposal of multitask ATM cells and the required new ADPCM encoder. This scheme combines three tasks together, namely, reducing cell packeting delay, avoiding breakdown of speech decoders due to one lost cell, compensating or replacing the lost information segment, by dividing the cell payload field into two parts——main and additional information fields, the latter again consists of synchronization information and the coded speech information contained in the last cell.

首先以ATM网络为例，提出了新的信息分组多任务装配法，以及对应此方法的新型ADPCM语音编码系统，这种方法中，利用特殊设计的编码器，使ATM信元负载信息域，由主要和附加用户信息两部分组成，后者又由同步信息和前一个信元语音段信息组成，通过选择和调节信元中两部分信息域的比例，实现了小的分组装配时延、高的分组丢失补偿质量、强的阻断误差传递功能三者的结合。

Electricity Charges management information system against the current charges collection difficult circumstances, such as trouble to design management software, Charges is a practical management information system, managers can through the appropriate module, the information in the database update, delete, and query, Recording data of meter reading of electricity tariff, can have a variety of ways to charge fees on a variety of ways to enquiries, information statements on electricity generation, the basic data for the revision and the use of the system administrator updated information, delete, operators permission to set up, modify your password, and other functions.

The Lightweight Directory Access Protocol server organization was used to share metadata of the information resource. Resource supervisor, data extractor and news main line were realized by object buffer pool, multithreading and news main line. The complex structure of rockbottom shielded by system engine and the XML technology was unified to solve problems of multi-template demonstration and sharing information alternately. The information share in Internet environment between the different application systems has been realized effectively.
