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.
一個校園弱電系統的建設，其最終建設目標是將新校區建設成為一個資訊化時代下的高水平的智慧化、數字化校園，從而為學校的教育資訊化打下堅實的基礎。透過在某學校新校區弱電系統設計中的體會，談談智慧化校園弱電系統整合的一點思考。
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
弱電系統設計方案依據應結合使用者需求，並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。以滿足使用者實際應用需求為原則，堅持先進，相容傳統，實現系統整合和系統互聯、資源整合、資訊共享。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。系統建設方案需要充分參考國內外先進的產品和技術，結合實際情況，使建成的系統不但能反映當今的先進水平，而且具有相當的發展潛力，讓中心設施達到十年不落後；
(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。採用開放式架構、標準化介面和協議，具有良好的相容性和可擴充套件性，其中平臺軟體的設計採用分層的模組化結構，以達到設定修改靈活，擴充方便，適應業務的發展變化。
(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。網路環境下資訊傳輸和資料儲存注重安全，保障系統網路的安全可靠性，避免遭到惡意攻擊和資料被非法提取的現象出現，安全要求高的系統採用專網專用，與其它網路物理隔離，完全保障資料的安全。
(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）擴充套件性原則。技術選型除了考慮先進、實用，還必須考慮系統的擴充套件性，系統容量應該有可持續發展的考慮；
(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、技術措施、裝置效能、系統管理、廠商技術支援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，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系統主要包含：校園綜合佈線系統、網路系統、電話通訊系統、安防監控系統、一卡通系統、停車場管理系統、校園廣播系統、有線電視系統等弱電系統。可見一個校園弱電系統很多，如按以往方案，每個系統獨立設計，獨立建設，必然會造成重複建設、資源浪費，同時增加系統管理複雜度。
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、規劃現代化的“數字化校園”。校園弱電系統應建設採取“統一規劃、基礎先行、面向需求、分步實施”的建設思路實施。首先做好統籌考慮，最佳化設計，可避免各系統重複配置造成資源浪費，同時也方便建成後統一管理維護，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）建立校園骨幹光纖網路：為校園弱電系統如資訊網路、影片監控、電話、廣播、電視、一卡通等系統提供一條統一的高速光纖資訊通道。並在校園骨幹網建一套頻寬萬兆的骨幹資料傳輸專網，為校園弱電系統（除資料網外）提供統一的傳輸通道。每個弱電系統主傳輸網都在傳輸專網上，系統之間透過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。設計時必須考慮室內外管道系統的預留應滿足建成後各個系統需要，並避免將來系統擴充套件時沒有足夠的預留管道，從而破壞整體建築結構以及裝修。
(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）影片監控、電話、廣播等弱電採用先進的符合現代技術發展潮流的IP 網路架構，透過乙太網線和光纖傳輸資訊。資料網路點採用六類雙絞線，語音等其他系統均採用超五類雙絞線，一卡通系統可用雙絞線的兩芯。這樣一來，方便多個統一採用先進的結構化佈線系統佈線。
(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.
結構化佈線相比傳統佈線有如下優勢。
Compared with the traditional structured cabling wiring has the following advantages.
（4）弱電系統中的不間斷電源、伺服器、儲存等資訊裝置納入統一規劃：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；除資訊網路以外的其他弱電系統的伺服器、儲存裝置統一規劃，校園建立統一的IP 儲存網路，並配置在校園資訊機房。在整個校園建成一個標準的資料中心，為校園所有弱電系統提供服務，使用者只須在終端進行管理和維護。
(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。才能建好一個先進又實用的智慧化、數字化校園，為學校的教學、科研、辦公等提供一個堅強的資訊化平臺。
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.
