Description

一种可以在三相电上使用的电力网桥
技术领域
本实用新型涉及一种网络设备，尤其涉及一种网桥。
背景技术
传统互联网在接入用户端时采用LAN或ADSL的接入方式，具有诸多缺点。采用LAN的接入方式，其运营商施工成本高，工期长，客户端上网位置不灵活。采用ADSL的接入方式，其运营商的施工成本高，工期长，而且资费高，网速受气候的影响，客户端上网位置不灵活。
最近，人们研究开发了一种电力线载波技术，将其应用在电力网桥上，通过电力线传输宽带、视频、音频信号。但目前的电力网桥有很大的使用局限性，只能使用在两相电力线上。由于目前电力线发展到家庭里，很多都转变为三相电，而目前的电力网桥在三相电的环境下，两两互相不能通信，因此不能正常工作。
发明内容
本实用新型的电力网桥突破了传统互联网接入方式的瓶颈，不但网速快，上网位置灵活，而且运营商施工成本低、工期短，以及现有技术中电力网桥在三相电上不能传输信号的局限，公开了一种可以在三相电上传输的电力网桥。本实用新型的电力网桥使用新颖的电力线载波模块，利用现有的三相电力线路做数据传输通道，实现了用户通过三相电力线高速上网。
本实用新型的电力网桥包括电源、输入接口和输出接口，还包括设备强弱电结合模块、防雷装置和耦合电路，所述输入接口用于连接至电表空开，所述输出接口用于连接至电力调制解调器，所述电力网桥利用所述耦合电路通过耦合线圈将信号耦合到三相电力线上。
附图说明
图1为本实用新型的电力网桥的结构示意图。
图2为本实用新型的电力网桥中耦合电路的电路图。
具体实施方式
为了使本领域技术人员更清楚地理解本实用新型的启动球，下面参考附图描述其具体实施方式。
参考图1，电力网桥1包括电源2、输入接口3和输出接口4，输入接口3用于连接至电表空开，输出接口4用于连接至电力调制解调器。电力网桥1连接至电表空开，其将网络信号加载至家庭电源线上。在家庭内任何一个插座上使用电力调制解调器，即可以将网络信号传至其中。该电力网桥1还包括设备强弱电结合模块5和防雷装置6。设备强弱电结合模块5使得用户端在用电高峰期上网不受电压波动影响，安全稳定。防雷装置6使得设备在恶劣的高温天气和强风暴雨气候时，运行稳定。
电力网桥1还包括耦合电路7，其通过耦合线圈将信号耦合到三相电力线上传输。耦合电路7的电路图如图2所示。
该电力网桥的电源规格为100V-240VAC 60/50Hz。调制技术为OFDM技术。运用了128-bitAES加密技术，让资料传输自动加密保护。该电力网桥为自适应产品，使用时随插即用。网络传输速率约65-85M，且实现电力三相互通。电力线频率范围为4.3-20.9MHz。
本实用新型的电力网桥不但可以用于普通的互联网上网，而且可用于承载语音、数据、视频图像、可视电话、IPTV、VOIP、摄像监控、家庭智能中心等多种用途。
