synchronous backup software does not respond to the rest of the data to be modified. In order to ensure maximum server exception, saving some data, synchronization of real-time backup software should have high, that delay does not exceed 1 minute. Offsite backups that must be supported across network segments. In accordance with the above requirements for development our dedicated backup software. After development, wing that opened in salt on high speed test results meet the design requirementsWith the passing of time, it is preparing source Huan of Hubei industrial investment company limited factory close to the planning of the day looks like, planning human ideals gradually into an entity, spread out before us. Security plan enters the deployed State. After listening to your business objective for the leaders of security, I quickly people with loyalty to the cause of security, as well as previous security experience, combined with peer pioneers of success stories or experiences. Border security on your business ideas and suggestions to make as follows: 1.1 after careful analysis of a blueprint of the enterprise, taking into account your enterprise factory boundary: 540.65M x 234.24M rectangular site. 1.2 scope for such dachangqu, I recommend the solid border security deployment, for a range of reasons, whether we use infrared radiation, electronic fences, alarm had done there, where the response. Because the factory could not spend a great deal of manpower cost to post three steps, five steps and a whistle. As we all know, under the current form of human resources costs much higher than the cost of all scientific and technological input. In order to better achieve the goal of planners, as well as for Active solid border defense work. We recommend that you use infrared radiation or linkage of electronic fences with video security deployment to achieve security goals. 1.3 in accordance with the device on the wall of the compound properties and parameters to a reasonable plan to install the infrared radiation equipment or fences and electronic equipment as well as video surveillance equipment, the specific needs of the equipment and materials quantities we will detail later. 1.4 the programme according to your companys site to see and listen to the leadership proposal, and in accordance with the actual needs of the project, with reference to the relevant international standards and national standards, combined with the experience accumulated by the company engaged in multiple projects, prepare the technology package. If the contents or any other aspect of the programme has not detailed where we welcome your valuable comments. Second, the design principles of the project design follows technology advanced, functional, stable and cost-saving principles. And considering construction, maintenance and operation, and for future development, expansion, reconstruction and other factors leave room for expansion. Design elements of the system is the systematic, integrated and comprehensive; design has the scientificity, reasonability and operability. Its has following principles: 2.1, and advanced and applicability used currently most advanced of soft, and hardware and the network technology, errors rate low, compatible sex strong, upgrade easy, used module type structure, expansion convenient, no repeat construction investment, system of technology performance and quality index should reached international leading level; while, system of installation debugging, and software programming and operation using and should simple, easy master, for China conditions and this project of features. Set the number of advanced technology in a the systems, reflects the current level of the latest development of computer and network technology, adapted to the requirements of the times. While the system is the system used for various management levels, its functions are configured to provide the user with comfortable, safe, fast and convenient to3.1, the intelligent building design standards (GB/t 50314-2000) 3.2, the design standard for intelligent building systems engineering (DB32/191-1998) 3.3, the code电化学法制备Cu2O/ZnO复合膜的研究安 徽 建 筑 大 学毕 业 设 计 专 业化学工程与工艺班 级09化工（1）班学生姓名 贾 广 玖学 号09206040107课 题 2万吨/年醋酸乙烯工艺设计 合成工段及反应器设计指导教师陈 广 美 2012年6月 12日for engineering design of generic cabling system for city residential buildings (CECS/119-2000) 3.4, code for design of buildings and campus cable systems engineering (GB/T50311-2000) 3.5, the code for electrical design of civil buildings (JGJ/ T16-92) 3.6, the code for civil closed circuit monitoring TV system engineering technology (GB/50198-94) 3.7, the types of system earthing and safety technical requirements (GB14050-93) 3.8, of the security engineering procedures and requirements (GA/T75-94) 3.9, the rules of security engineering acceptance
