具体实施方式detailed description
下面结合附图对本发明优选实施例作详细说明。The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.
本发明中AU单元实现了4路信源的耦合接入，并将4路信号转换成数字信号，打包、组帧后通过光纤传输和iHUB单元相连，多个AU单元可以将多个不同物理位置的信源通过光纤汇聚到iHUB单元，从而实现不同物理位置的多信源汇聚接入到iHUB单元；iHUB单元一方面将多AU信源进行汇聚，同时可以将本地Wi-Fi、RFID、物联网、监控等信号接入，从而形成多点信源汇聚而成的“信源池”，另一方面iHUB单元根据大楼覆盖点RU的不同需求将信源池里的信源进行智能调度和分配，通过传输介质(比如光纤、五类线、六类线、同轴电缆等传输媒介)将“需要的信源”分配到各个远端覆盖单元RU，从而实现多点覆盖功能；RU(Remote Unite)将iHUB单元分配的信源进行数模转换、射频放大，从而实现多点的信号覆盖，如图1所示。同时每个RU具有用户数量、流量信息、位置信息等统计功能，可以根据承载负荷情况，将监控信息上报给iHUB，iHUB可以该信息对信源进行智能调度，从而实现多点智能覆盖功能。 In the invention, the AU unit realizes the coupling access of four sources, and converts the four signals into digital signals, which are packaged, framed and connected by the optical fiber transmission and the iHUB unit, and the plurality of AU units can have multiple different physical positions. The source is aggregated to the iHUB unit through the optical fiber, so that multiple sources of different physical locations are aggregated and connected to the iHUB unit; the iHUB unit aggregates multiple AU sources on the one hand, and can simultaneously connect local Wi-Fi, RFID, and the Internet of Things. , monitoring and other signal access, thereby forming a "source pool" of multi-point source convergence, on the other hand, the iHUB unit intelligently dispatches and distributes the source in the source pool according to the different needs of the building coverage point RU. The "required source" is distributed to each remote coverage unit RU through a transmission medium (such as a fiber, a Category 5 line, a Category 6 line, a coaxial cable, etc.) to implement a multi-point coverage function; RU (Remote Unite) The source of the iHUB unit is digital-to-analog converted and RF-amplified to achieve multi-point signal coverage, as shown in Figure 1. At the same time, each RU has a statistical function such as the number of users, the traffic information, and the location information. The monitoring information can be reported to the iHUB according to the load carrying situation. The iHUB can intelligently schedule the information to implement the multi-point intelligent coverage function.
对于多AU信源接入，汇聚到iHUB单元，根据物理位置，我们可以通过先将其它AU信源先汇聚到AU1，AU1将所有AU信号汇聚，打包，组帧，通过光纤传输到iHUB，如图2所示。由于光纤速率决定了信源的多少，该场景适合多个不同物理地址AU信源汇聚，且多AU总信源所需要的传输总速率满足单根光纤速率传输的场景。For multi-AU source access, it is aggregated to the iHUB unit. According to the physical location, we can first aggregate other AU sources to AU1. AU1 aggregates all AU signals, packs them, frames them, and transmits them to iHUB through optical fibers. Figure 2 shows. Because the fiber rate determines the number of sources, the scenario is suitable for aggregating multiple AU sources with different physical addresses, and the total transmission rate required by the multi-AU total source satisfies the scenario of single fiber rate transmission.
由于iHUB既汇聚了来至不同物理地址，不同AU的信源，同时又汇聚了iHUB本地的Wi-Fi、RFID、物联网、监控等信源，形成了一个“信源池”。如果将信源池里所有信源全都分配到每一个RU进行室内信号覆盖的话，一方面iHUB到每个RU之间的传输媒介需要承载过大的速率容量，成本昂贵，另一方面，要想对某个RU或者某个大楼进行信源增加或者减少的话，我们就需要根据大楼的实际需要来合理分配信源，如图3所示。该设计十分有利于本系统后续的信源智能调度，实时分配，容量扩容后后续其它信源融合应用。Since iHUB aggregates the source of different physical addresses and different AUs, it also aggregates the local Wi-Fi, RFID, Internet of Things, monitoring and other sources of iHUB, forming a “source pool”. If all the sources in the source pool are allocated to each RU for indoor signal coverage, on the one hand, the transmission medium between the iHUB and each RU needs to carry excessive rate capacity, which is expensive, on the other hand, To increase or decrease the source of a RU or a building, we need to allocate the source reasonably according to the actual needs of the building, as shown in Figure 3. The design is very beneficial to the subsequent intelligent source scheduling of the system, real-time allocation, and subsequent capacity fusion applications after capacity expansion.
