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(gè)校園弱電系統的建設，其最終建設目標是將新校區建設成為一個(gè)信息化時(shí)代下的高水平的智能化、數字化校園，從而為學(xué)校的教育信息化打下堅實(shí)的基礎。通過(guò)在某學(xué)校新校區弱電系統設計中的體會(huì )，談?wù)勚悄芑@弱電系統集成的一點(diǎn)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
弱電系統設計方案依據應結合用戶(hù)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(shí)用原則。以滿(mǎn)足用戶(hù)實(shí)際應用需求為原則，堅持先進(jìn)，兼容傳統，實(shí)現系統集成和系統互聯(lián)、資源整合、信息共享。把實(shí)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(jìn)性原則。系統建設方案需要充分參考國內外先進(jìn)的產(chǎn)品和技術(shù)，結合實(shí)際情況，使建成的系統不但能反映當今的先進(jìn)水平，而且具有相當的發(fā)展潛力，讓中心設施達到十年不落后；
(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(kāi)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(wù)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(luò )環(huán)境下信息傳輸和數據存儲注重安全，保障系統網(wǎng)絡(luò )的安全可靠性，避免遭到惡意攻擊和數據被非法提取的現象出現，安全要求高的系統采用專(zhuān)網(wǎng)專(zhuān)用，與其它網(wǎng)絡(luò )物理隔離，完全保障數據的安全。
(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(shù)選型除了考慮先進(jìn)、實(shí)用，還必須考慮系統的擴展性，系統容量應該有可持續發(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）穩定性原則。從系統結構、技術(shù)措施、設備性能、系統管理、廠(chǎng)商技術(shù)支持及維修能力等方面保障系統的可靠性和穩定性；
(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。系統應具備自檢、故障診斷及故障弱化功能，在出現故障時(shí)，應能得到及時(shí)、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(gè)校園的弱電系統系統主要包含：校園綜合布線(xiàn)系統、網(wǎng)絡(luò )系統、電話(huà)通信系統、安防監控系統、一卡通系統、停車(chē)場(chǎng)管理系統、校園廣播系統、有線(xiàn)電視系統等弱電系統�？梢�(jiàn)一個(gè)校園弱電系統很多，如按以往方案，每個(gè)系統獨立設計，獨立建設，必然會(huì )造成重復建設、資源浪費，同時(shí)增加系統管理復雜度。
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(diǎn)、規劃現代化的“數字化校園”。校園弱電系統應建設采取“統一規劃、基礎先行、面向需求、分步實(shí)施”的建設思路實(shí)施。首先做好統籌考慮，優(yōu)化設計，可避免各系統重復配置造成資源浪費，同時(shí)也方便建成后統一管理維護，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.
�。�1）建立校園骨干光纖網(wǎng)絡(luò )：為校園弱電系統如信息網(wǎng)絡(luò )、視頻監控、電話(huà)、廣播、電視、一卡通等系統提供一條統一的高速光纖信息通道。并在校園骨干網(wǎng)建一套帶寬萬(wàn)兆的骨干數據傳輸專(zhuān)網(wǎng)，為校園弱電系統（除數據網(wǎng)外）提供統一的傳輸通道。每個(gè)弱電系統主傳輸網(wǎng)都在傳輸專(zhuān)網(wǎng)上，系統之間通過(guò)VLAN 邏輯隔離。
(1) to establish the campus backbone fiber optic network: light-current system such as information network for college campus, video monitoring, telephone, radio, TV, cartoon and so on the system to provide a unified high-speed optical fiber channel of information. And in the campus backbone network to build a set of the backbone bandwidth Wan Zhao private network data transmission, weak current system for campus (except data network) to provide uniform transmission channel. Every weak current system main transmission on the transmission of private network, by VLAN logic isolation between systems.
�。�2）建立校園弱電綜合管道系統，作為數字化校園各弱電系統的'基礎通道。弱電綜合管道系統分為室內綜合管道系統和室外綜合管道系統。設計時(shí)必須考慮室內外管道系統的預留應滿(mǎn)足建成后各個(gè)系統需要，并避免將來(lái)系統擴展時(shí)沒(méi)有足夠的預留管道，從而破壞整體建筑結構以及裝修。
(2) to establish the campus weak current integrated pipeline system, as the basis of digital campus all elv system channel. Weak current integrated pipeline system is divided into indoor integrated pipeline system and outdoor pipeline system. Design of indoor and outdoor pipeline system must be considered when the reserved should meet the requirements of after the completion of each system, and to avoid future system
expansion when there is not enough reserved pipe, undermining the overall structure and decoration.
�。�3）視頻監控、電話(huà)、廣播等弱電采用先進(jìn)的符合現代技術(shù)發(fā)展潮流的IP 網(wǎng)絡(luò )架構，通過(guò)以太網(wǎng)線(xiàn)和光纖傳輸信息。數據網(wǎng)絡(luò )點(diǎn)采用六類(lèi)雙絞線(xiàn)，語(yǔ)音等其他系統均采用超五類(lèi)雙絞線(xiàn)，一卡通系統可用雙絞線(xiàn)的兩芯。這樣一來(lái)，方便多個(gè)統一采用先進(jìn)的結構化布線(xiàn)系統布線(xiàn)。
(3) video monitor, telephone, radio, and other elv keeping pace with the development of modern technology with advanced IP network architecture, via Ethernet cable and optical fiber transmission of information. Data network point by six kind of twisted pair, speech, and other system adopt super five kind of twisted pair, one cartoon system available two core of twisted-pair cable. Thus, convenient more unified adopts advanced structured cabling system wiring.
結構化布線(xiàn)相比傳統布線(xiàn)有如下優(yōu)勢。
Compared with the traditional structured cabling wiring has the following advantages.
�。�4）弱電系統中的不間斷電源、服務(wù)器、存儲等信息設備納入統一規劃：建立校園一套統一的不間斷電源系統，為校園弱電系統統一供電；除信息網(wǎng)絡(luò )以外的其他弱電系統的服務(wù)器、存儲設備統一規劃，校園建立統一的IP 存儲網(wǎng)絡(luò )，并配置在校園信息機房。在整個(gè)校園建成一個(gè)標準的數據中心，為校園所有弱電系統提供服務(wù)，用戶(hù)只須在終端進(jìn)行管理和維護。
(4) in the weak current system information such as uninterruptible power supply, server, storage device into the unified plan: to establish a unified campus uninterruptible power supply system, weak current system for campus unity power supply; Other elv systems other than the information network of servers, storage equipment and unified planning, the campus to establish a unified IP network storage, and configure information room on
campus. In a standard data center, the completion of the entire campus for all elv systems to provide services in schools, in terminal user only for management and maintenance. 3結論
3 conclusion
校園建設中，弱電系統很多，只有做到統一規劃、統籌考慮，統一建設。才能建好一個(gè)先進(jìn)又實(shí)用的智能化、數字化校園，為學(xué)校的教學(xué)、科研、辦公等提供一個(gè)堅強的信息化平臺。
There are many campus construction, the weak current system, is to do a unified planning, overall consideration, unified construction. To build an advanced and practical intelligence, digital campus, the school teaching, scientific research, office, etc. Provide a strong information platform.
