【摘要】：随着我国经济的不断发展,楼宇内保调度指挥系统的需求日趋多样化。在处理楼宇管理事务的过程中,楼宇内保调度指挥系统能够实现决策部门与行动机构的有效沟通的功能,是整个楼宇内部安保信息高速传输通道和联络平台之一。楼宇内保调度指挥系统能够实时监控楼宇内部和及时掌握现场状态,广泛应用于酒店、写字楼、商业中心等领域。基于WLAN(Wireless Local AreaNetworks,无线局域网)的楼宇内保无线指挥调度系统具有半双工单呼和组呼功能,能满足专业通信的需要;同时,楼宇内保无线指挥调度系统又能实现楼宇内部信号全面覆盖和视频、短信以及文件等多媒体数据传输。因此,完成楼宇内保无线指挥调度系统的工程设计具有较高的实用价值。本文在综述了国内外楼宇内保指挥调度系统发展状况的基础上,首先,根据无线指挥调度系统的组成和科技大厦有线和无线网络部署的现状,给出了楼宇内保无线指挥调度系统的覆盖需求、性能需求以及功能需求,并基于OFDM(Orthogonal Frequency Division Multiplexing,正交频分复用)的电力线载波通信原理,设计了室内宽带电力线载波通信方案,解决了楼宇内部分区域不能布设网线导致无线信号无法覆盖的问题;然后,根据无线指挥调度系统核心网的架构,设计了科技大厦内保无线调度指挥系统核心网的网络拓扑,规划了系统的设备网络地址;并根据WLAN室外信道传输损耗模型和WLAN室内信道传输损耗模型,计算了 AP(AccessPoint,无线接入点)覆盖范围,设计了科技大厦无线接入点的部署方案,给出了各楼层AP的无线信道分配;最后,利用InSSIDer软件和Xshell软件等工具,对系统进行覆盖测试和功能测试,测试结果表明,楼宇内保无线指挥调度系统的工程设计能够实现楼宇内无线信号的全面覆盖,实现了系统的注册、单呼、组呼、视频通话、呼叫转移、其他呼叫、调度台、图片和文件传输、短消息传输、终端本地管理以及网络管理等功能。
[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.
