電子信息專業(yè)英文論文該如何寫呢?寫些什么內容呢?本文是小編精心編輯的電子信息專業(yè)英文論文,希望能幫助到你!
信息技術的應用與普及,現(xiàn)代信息技術正在向教學、科研、管理的每一個環(huán)節(jié)滲透,將改變傳統(tǒng)的教學模式并大幅度提高教育資源的利用效率。數(shù)字化校園、網(wǎng)上大學已被人們熟悉,教育正在走向全面的信息化。 The application and popularization of information technology, modern information
technology to the teaching, scientific research and management of each link, will change the traditional teaching mode and greatly improve the utilization efficiency of education resources. Online university digital campus, has been familiar, education is to the comprehensive information.
一個校園弱電系統(tǒng)的建設,其最終建設目標是將新校區(qū)建設成為一個信息化時代下的高水平的智能化、數(shù)字化校園,從而為學校的教育信息化打下堅實的基礎。通過在某學校新校區(qū)弱電系統(tǒng)設計中的體會,談談智能化校園弱電系統(tǒng)集成的一點思考。
A weak current system of campus construction, construction of its ultimate goal is to become a new campus construction information era under the high level of intelligence, digital campus, so as to lay a solid foundation for the school education informatization. In the new campus of a school in the weak current system design experience, talk about a bit weak current system integration of intelligent campus thinking.
1設計原則
1 design principles
弱電系統(tǒng)設計方案依據(jù)應結合用戶需求,并在設計中遵循以下設計原則:
Weak current system design scheme on the basis of should be combined with the user requirements, and follow the following principles in the design:
(1)實用原則。以滿足用戶實際應用需求為原則,堅持先進,兼容傳統(tǒng),實現(xiàn)系統(tǒng)集成和系統(tǒng)互聯(lián)、資源整合、信息共享。把實用性放在第一位;
(1) the practical principles. Practical application in order to meet user needs as the
principle, adhere to the advanced, compatible with the traditional, system integration and
system interconnection, resources integration and information sharing. The practicability in the first place;
(2)先進性原則。系統(tǒng)建設方案需要充分參考國內外先進的產(chǎn)品和技術,結合實際情況,使建成的系統(tǒng)不但能反映當今的先進水平,而且具有相當?shù)陌l(fā)展?jié)摿Γ屩行脑O施達到十年不落后;
(2) the advanced principles. System construction plan requires full reference advanced products and technologies at home and abroad, combined with the actual situation, make the completed system can not only reflect today's advanced level, and has considerable development potential, don't get behind center facilities at ten years;
(3)標準化原則。采用開放式架構、標準化接口和協(xié)議,具有良好的兼容性和可擴展性,其中平臺軟件的設計采用分層的模塊化結構,以達到設置修改靈活,擴充方便,適應業(yè)務的發(fā)展變化。
(3) the principle of standardization. Using an open architecture, standardized interfaces and protocols, has good compatibility and expansibility, including the design of the platform software adopts hierarchical modular structure, modify Settings in order to achieve flexible, expansion of convenient, adapt to changes in the business.
(4)安全原則。網(wǎng)絡環(huán)境下信息傳輸和數(shù)據(jù)存儲注重安全,保障系統(tǒng)網(wǎng)絡的安全可靠性,避免遭到惡意攻擊和數(shù)據(jù)被非法提取的現(xiàn)象出現(xiàn),安全要求高的系統(tǒng)采用專網(wǎng)專用,與其它網(wǎng)絡物理隔離,完全保障數(shù)據(jù)的安全。
(4) security principle. Under the network environment information transmission and data storage pay attention to safety, guarantee the safety and reliability of the system network, prevent malicious attack and data is the phenomenon of illegal extraction, high security requirements of system adopts the private network is special, and other physical isolation network, fully protect the safety of data.
(5)擴展性原則。技術選型除了考慮先進、實用,還必須考慮系統(tǒng)的擴展性,系統(tǒng)容量應該有可持續(xù)發(fā)展的.考慮;
(5) the principle of extensibility. Technology selection in addition to considering the advanced, practical, must also consider the extensibility of system, system capacity should be a consideration of sustainable development;
(6)穩(wěn)定性原則。從系統(tǒng)結構、技術措施、設備性能、系統(tǒng)管理、廠商技術支持及維修能力等方面保障系統(tǒng)的可靠性和穩(wěn)定性;
(6) stability principle. From the system structure, technical measures, equipment performance, system management, ability of manufacturer's technical support and maintenance support system reliability and stability;
(7)可維護性原則。系統(tǒng)應具備自檢、故障診斷及故障弱化功能,在出現(xiàn)故障時,應能得到及時、快速的修復。
(7) maintainability principles. System should have the introspection, fault diagnosis and fault weakening function, in the event of a failure, should be able to get timely and rapid repair.
2設計思想
2 design idea
一個校園的弱電系統(tǒng)系統(tǒng)主要包含:校園綜合布線系統(tǒng)、網(wǎng)絡系統(tǒng)、電話通信系統(tǒng)、安防監(jiān)控系統(tǒng)、一卡通系統(tǒng)、停車場管理系統(tǒng)、校園廣播系統(tǒng)、有線電視系統(tǒng)等弱電系統(tǒng)。可見一個校園弱電系統(tǒng)很多,如按以往方案,每個系統(tǒng)獨立設計,獨立建設,必然會造成重復建設、資源浪費,同時增加系統(tǒng)管理復雜度。
A campus of elv system system mainly include: campus integrated wiring system, network system, telephone communication systems, security monitoring system, IC card system, parking management system, the campus broadcast system, weak current system such as cable television system. Is a campus a lot of weak current systems, such as according to the previous plan, each system independent design, independent construction, will inevitably cause repetitive construction and the waste of resources, and increase system management complexity.
為建設好高起點、規(guī)劃現(xiàn)代化的“數(shù)字化校園”。校園弱電系統(tǒng)應建設采取“統(tǒng)一規(guī)劃、基礎先行、面向需求、分步實施”的建設思路實施。首先做好統(tǒng)籌考慮,優(yōu)化設計,可避免各系統(tǒng)重復配置造成資源浪費,同時也方便建成后統(tǒng)一管理維護,提高維護效率。
To build a high starting point, the modernization of planning "digital campus". Campus light-current system should take the construction of "unified planning, leading, demand oriented, step-by-step implementation of" the construction of the ideas. First do overall consideration, optimization design, can avoid repeat each system configuration cause resource waste, but also convenient maintenance after the completion of unified management, improve the efficiency of maintenance.
