具体实施方式
为使本领域的普通技术人员更加清楚地理解本发明，以下结合附图和实施例对本发明做进一步的阐述。
参照图1至图2所示，在一些实施例中，该列车车厢WIFI覆盖网络1包括列车有线以太网通信子系统11、列车无线覆盖子系统12、车地通信子系统13和车载服务子系统14。其中，列车有线以太网通信子系统11包括分布在每节车厢内的交换机111和用于连接交换机的以太网网线，以太网网线跨接车厢使每节车厢内的交换机互联以形成整车环网。列车无线覆盖子系统12包括设置于每节车厢内的至少两个无线AP(ACESS PIONT接入点)和与无线AP配套连接的若干天线，无线AP与对应车厢内的交换机连接，用于为终端提供无线接入点。车地通信子系统包括车地AP和与车地AP配套连接的车地天线，用于为列车内网络数据提供通信通道，更新列车车载服务器的内容。车载服务子系统14包括 车载服务器，其用于将部分视频、音频、媒体数据进行局域网内缓存，为访问终端提供高宽带服务。该发明通过在车厢内部署无线AP和天线，实现无线WIFI对每节车厢的全面覆盖，满足乘客在车厢不同位置时都能够通过均匀分布的天线获得良好的无线信号覆盖质量。这种设计方式避免了现有轨道旁无线覆盖系统由于穿透列车金属车体造成的信号损失，提升了列车满载情况下的用户接入能力。
参照图3所示，本发明实施例的列车有线以太网通信子系统11的示意图。该列车有线以太网通信子系统11包括分布在每节车厢内的交换机111和用于连接交换机111的以太网网线，以太网网线跨接车厢使每节车厢内的交换机互联以形成整车环网。本实施例中，该列车有六节车厢，在六节车厢内依次设置有交换机交换机1111、交换机1112、交换机1113、交换机1114、交换机1115、交换机1116，且六个交换机相连接以形成环网。即每个交换机都有两个以太网网线进行连接。藉由此设置，整个车厢跨接互联形成整车环网，能够保证在某一条线路发生故障时整个列车网络依然能正常运行，以增加列车内有线以太网的稳定性。优选地，该交换机111为为千兆工业交换机，其均匀分布与每节车厢内。以太网网线选用8芯线，该8芯以太网网线可适用于大带宽的应用。
具体地，鉴于每个无线接入点覆盖范围不超过1/2车厢长度，每个天线均匀分布在1/2长度车厢。在本实施例中，优选地，每节车厢包括两个无线AP，每一个无线AP分别连接配套的三个天线，用以完成无线WIFI对每节车厢全面覆盖。其中，每个无线AP与对应车厢内的交换机连接，用于为终端提供无线接入点。考虑到无线通信信号是按直线方向传播的，要是在传输的过程中遇到有障碍物的话，无线通信信号的强度就会受到削弱，特别是遇到金属障碍物时，无线信号的衰减幅度更是巨大。为了避免无线信号遭受到外来障碍物的干扰，应 将无线接入点和天线设置高处。在本实施例中，无线AP和天线安装在车厢的侧盖板内，以保证无线信号的稳定传输。无线AP与设置在本车厢的交换机连接，该交换机为无线接入点提供电源和带宽。
在本实施例中，该车地通信子系统13包括车地无线接入点和与车地无线接入点配套的车地天线，用于为列车内网络数据提供通信通道，更新列车车载服务器的内容。具体地，车地AP包括地面无线AP和车载无线AP，车地天线包括与所述地面无线AP相配套的地面天线及与所述车载无线AP相配套的车载天线，地面无线AP与车载无线AP采用802.11ac协议无线技术进行无线桥接通信。02.11ac是专门为5GHz频段设计，支持MIMO(Multiple-Input Multiple-Output多入多出)技术，其能够将现有无线网技术吞吐性能提高到千兆网络级。藉由此通信协议，轨旁无线AP与车载无线AP的无线通信能够实现更快，更稳定。
优选地，该车地通信子系统13列车两套车载无线AP及与车载无线AP配套的车载天线，其分别设置于列车的车头和车尾处。通过将车载无线AP及配套车载天线设置在列车头和列车尾的负载分担方式，不仅可以有效扩大车地带宽，而且当一端发生故障时，网络不会发生中断，保证了车地通信网络的稳定性。该车地通信子系统13主要接收地面信号，以及在地面有无线信号的路段连接地面，提供传输通道。
车载服务子系统14包括车载服务器，其用于将部分视频、音频、媒体数据进行局域网内缓存，为访问终端提供高宽带服务。终端子系统可以为列车各节车厢内的乘客所携带的智能设备，如智能手机、平板电脑等。同时，乘客可以通过车载无线WIFI与车载服务器进行通信。藉由车载服务器为乘客提供文本、音频、视频等丰富的多媒体本地内容访问，以实现车厢内信息服务系统与乘客之间的互动连接，相对目前传统、单一的服务模式，本发明可以为旅客提供全 方位的、互动性的服务信息。
以上所述仅为本发明的优选实施例，而非对本发明做任何形式上的限制。本领域的技术人员可在上述实施例的基础上施以各种等同的更改和改进，凡在权利要求范围内所做的等同变化或修饰，均应落入本发明的保护范围之内。
