Description

链路备份、电源备份方法、装置及系统、存储介质 技术领域
本发明涉及通讯领域，特别是涉及一种链路备份方法、电源备份方法、链路备份装置、电源备份装置、链路和电源备份系统、以及相关计算机存储介质。
背景技术
随着通讯技术的高速发展，宽带电力线通信获得广泛应用，其利用现有的电力网，以电力线作为一种新型的信息传输媒介实现信号传输。以太网传输应用已经相当成熟，可以在传输信号的同时提供电源；其中，在近年来得到广泛应用之一的以太网为有源以太网技术(POE，Power over Ethernet)。
宽带电力线技术(BPL，Broadband over Power Lines)是一种允许数据在电力线上进行传输的技术，能够有效降低布线成本。人们经常把BPL称为电力线通信(PLC)。
POE指的是在现有的以太网Cat.5布线基础架构不作任何改动的情况下，在为一些基于IP的终端(如互联网协议(IP，Internet Protocol)电话机、无线局域网接入点(AP，Access Point)、网络摄像机等)传输数据信号的同时，还能为此类设备提供直流供电的技术。POE技术能在确保现有结构化布线安全的同时保证现有网络的正常运作，最大限度地降低成本。
简单来说，BPL技术就是将电力线作为通信链路，电力线在供电的同时可以传输数据信号；POE技术就是在以太网链路上提供电源，即数据链路可以为设备供电。
目前应用于以太网传输的系统为了保证链路的可靠传输，一般会做系 统备份保护，在正常传输链路断开时，保护(备份)链路可以工作，使系统能够正常传输。传统的备份保护需要两套POE设备和传输链路，以分别完成数据链路备份和供电电源备份，不利于节约成本和绿色节能。
针对相关技术中传统备份保护方案不利于节约成本和绿色节能的问题，目前尚未提出有效的解决方案。

下面结合上述通信链路和电源备份保护系统，通过实施例进行具体介绍。
实施例一：数据链路备份方案
图7是根据本发明实施例的实现链路备份方案的示意图，如图7所示：
假设A设备和B设备在正常运行过程中，即设备用电力线供电，使用以太网传输数据；当A设备的数据处理模块长时间(具体时长可以根据网络状况设定)接收不到B设备发送的以太网报文，则A设备向B设备发送检测报文，该报文需要B设备响应并进行应答，A经过一定时间没有收到B的响应报文，则A设备判断为A、B设备之间的以太网传输链路出现故障或者断开，这时候A设备和B设备互相收不到对方的数据，与此同时， B设备也进行同样的检测操作，数据切换控制模块根据数据链路的备份保护规则，将数据链路由E切换到F，数据链路切换后，A设备和B设备首先进行通信握手以确认之前的状态和切换后的状态，如果A设备和B设备的状态确认为同时已经切换到F链路，则通过链路F进行数据传输，此时BPL模块工作；如果握手确认的状态A设备是以太网链路作为数据的传输链路而B设备是以电力线作为数据的传输链路，则A设备和B设备同时切换回原来的数据传输链路，即使原来的数据传输链路存在故障也会切换回原来的传输链路，继续A设备和B设备继续判断链路状态直至状态正确。如果握手确认A设备和B设备的状态相同，这时点虚线提供的数据备份链路上的数据通过BPL模块经过数据链路F输入到数据处理模块以进行数据处理，至此实现了数据链路的备份保护。
就目前的技术而言，通过BPL链路进行数据传输的可靠性远不如通过以太网链路的数据通信，所以在A设备和B设备在使用备份的数据链路通信的同时，也同时发送以太网数据检测报文，当A设备和B设备之间以太网链路存在故障时，两个设备互相收不到对端的应答报文。当以太网链路修复后，A设备或B设备可以检测到对端的报文，同时发出响应报文，A设备发出检测报文，收到B设备的响应报文，B设备也有同样的操作，则A设备和B设备发出切换数据通信链路的请求报文给对端，在获得对端的响应报文答复后，A设备和B设备数据切换控制模块将通信链路切换到以太网通信链路。
实施例二：电源备份方案
图8是根据本发明实施例的实现电源备份方案的示意图，如图8所示：
假设A设备和B设备在正常运行过程中，B设备的供电电源出现问题，比如电源断电或者电压过低(电源模块中有检测电路，电压在某个区间为正常，电压超出该区间范围则告警)，电源模块具备检测设备供电电源的功 能，如果检测到C给B设备的供电超出正常的区间范围，则给数据处理模块发出告警信息；告警信号同时触发电源切换开关，切换供电电源，B设备中电源模块的供电就会由C提供电源切换到由D提供的电源。电源模块具备供电保持功能，在电源断开的20ms时间内能够正常输出供电电源，电源的切换操作要求在20ms内完成，可以保证电源供电的连续性，实现电源的软件换，设备实现了电源的备份保护。POE技术的应用已经比较成熟，电源可以一直使用POE供电。
实施例三：电源和数据链路同时备份方案
图9是根据本发明实施例的实现电源和数据链路同时备份方案的示意图，如图9所示：本发明实施例可以实现设备的数据链路和电源同时实现切换备份保护，即实施例一和实施例二的综合备份方案。
本发明实施例中，将BPL和POE技术相结合，提供了一种全新的电源和数据传输链路的备份保护解决方案。采用本发明实施例所描述的基于宽带电力线和POE技术组成的电源和数据链路备份系统，首先可以节约成本，因为传统的备份保护系统需要两套设备完成，利用本发明实施例只需一套设备即可以完成备份功能；其次有利于绿色节能环保，显然一套设备的能耗要小于两套设备的能耗；最后易于实施，不需要重新架设线路等基础设施，节约成本。

本发明实施例中，将BPL和POE技术相结合，提供了一种全新的电源和数据传输链路的备份保护解决方案。采用本发明实施例所描述的基于宽带电力线和POE技术组成的电源备份方法和装置、链路备份方法和装置、系统及相关计算机存储介质，首先可以节约成本，因为传统的备份保护系 统需要两套设备完成，利用本发明实施例只需一套设备即可以完成备份功能；其次有利于绿色节能环保，显然一套设备的能耗要小于两套设备的能耗；最后易于实施，不需要重新架设线路等基础设施，节约成本。
