【摘要】：隨著我國經(jīng)濟的不斷發(fā)展,樓宇內(nèi)保調(diào)度指揮系統(tǒng)的需求日趨多樣化。在處理樓宇管理事務(wù)的過程中,樓宇內(nèi)保調(diào)度指揮系統(tǒng)能夠?qū)崿F(xiàn)決策部門與行動機構(gòu)的有效溝通的功能,是整個樓宇內(nèi)部安保信息高速傳輸通道和聯(lián)絡(luò)平臺之一。樓宇內(nèi)保調(diào)度指揮系統(tǒng)能夠?qū)崟r監(jiān)控樓宇內(nèi)部和及時掌握現(xiàn)場狀態(tài),廣泛應(yīng)用于酒店、寫字樓、商業(yè)中心等領(lǐng)域。基于WLAN(Wireless Local AreaNetworks,無線局域網(wǎng))的樓宇內(nèi)保無線指揮調(diào)度系統(tǒng)具有半雙工單呼和組呼功能,能滿足專業(yè)通信的需要;同時,樓宇內(nèi)保無線指揮調(diào)度系統(tǒng)又能實現(xiàn)樓宇內(nèi)部信號全面覆蓋和視頻、短信以及文件等多媒體數(shù)據(jù)傳輸。因此,完成樓宇內(nèi)保無線指揮調(diào)度系統(tǒng)的工程設(shè)計具有較高的實用價值。本文在綜述了國內(nèi)外樓宇內(nèi)保指揮調(diào)度系統(tǒng)發(fā)展狀況的基礎(chǔ)上,首先,根據(jù)無線指揮調(diào)度系統(tǒng)的組成和科技大廈有線和無線網(wǎng)絡(luò)部署的現(xiàn)狀,給出了樓宇內(nèi)保無線指揮調(diào)度系統(tǒng)的覆蓋需求、性能需求以及功能需求,并基于OFDM(Orthogonal Frequency Division Multiplexing,正交頻分復(fù)用)的電力線載波通信原理,設(shè)計了室內(nèi)寬帶電力線載波通信方案,解決了樓宇內(nèi)部分區(qū)域不能布設(shè)網(wǎng)線導(dǎo)致無線信號無法覆蓋的問題;然后,根據(jù)無線指揮調(diào)度系統(tǒng)核心網(wǎng)的架構(gòu),設(shè)計了科技大廈內(nèi)保無線調(diào)度指揮系統(tǒng)核心網(wǎng)的網(wǎng)絡(luò)拓撲,規(guī)劃了系統(tǒng)的設(shè)備網(wǎng)絡(luò)地址;并根據(jù)WLAN室外信道傳輸損耗模型和WLAN室內(nèi)信道傳輸損耗模型,計算了 AP(AccessPoint,無線接入點)覆蓋范圍,設(shè)計了科技大廈無線接入點的部署方案,給出了各樓層AP的無線信道分配;最后,利用InSSIDer軟件和Xshell軟件等工具,對系統(tǒng)進行覆蓋測試和功能測試,測試結(jié)果表明,樓宇內(nèi)保無線指揮調(diào)度系統(tǒng)的工程設(shè)計能夠?qū)崿F(xiàn)樓宇內(nèi)無線信號的全面覆蓋,實現(xiàn)了系統(tǒng)的注冊、單呼、組呼、視頻通話、呼叫轉(zhuǎn)移、其他呼叫、調(diào)度臺、圖片和文件傳輸、短消息傳輸、終端本地管理以及網(wǎng)絡(luò)管理等功能。
[Abstract]:With the development of economy in our country, the demand of the internal security dispatching command system is becoming more and more diversified. In the process of dealing with the building management affairs. Building internal security dispatching command system can realize the function of effective communication between the decision-making department and the operational organization. It is one of the high-speed transmission channels and communication platform of the whole building internal security information. The building internal security dispatching command system can monitor the building interior in real time and grasp the scene status in time. It is widely used in hotels and office buildings. Business center and other fields. Based on WLAN(Wireless Local AreaNetworks. Wireless Local area Network (WLAN) has the functions of half-duplex single call and group call, which can meet the needs of professional communication. At the same time, the wireless command and scheduling system for building interior protection can also achieve the overall coverage of building internal signals and multimedia data transmission, such as video, short message and files. It is of high practical value to complete the engineering design of building internal protection wireless command and dispatch system. This paper summarizes the development of building internal security command and dispatch system at home and abroad, first of all. According to the composition of wireless command and scheduling system and the present situation of wired and wireless network deployment in science and technology building, the coverage requirements, performance requirements and function requirements of wireless command and scheduling system for building interior protection are given. The power line carrier communication principle based on OFDM(Orthogonal Frequency Division multiplexing and orthogonal frequency division multiplexing. The indoor wideband power line carrier communication scheme is designed to solve the problem that the wireless signal can not be covered by some areas of the building which can not be covered by the wireless signal. Then, according to the core network architecture of the wireless command and scheduling system, the network topology of the core network of the wireless dispatching command system is designed, and the network address of the system equipment is planned. According to the WLAN outdoor channel transmission loss model and the WLAN indoor channel transmission loss model, the coverage of WLAN access Point (Wireless access Point) is calculated. The deployment scheme of wireless access point in science and technology building is designed, and the wireless channel allocation of AP in each floor is given. Finally, using InSSIDer software and Xshell software tools, the system coverage test and functional testing, the test results show that. The engineering design of building internal protection wireless command and scheduling system can achieve the overall coverage of wireless signals in the building, and realize the system registration, single call, group call, video call, call transfer, other calls, scheduling station. Picture and file transfer, short message transmission, terminal local management and network management and other functions.
