具体实施方式
下面通过附图和实施例，对本公开的技术方案做进一步的详细描述。
本公开的能源路由器的一些实施例的示意图如图1A所示。能源路由器包括：
多个端口101，端口101是能源路由器与外部进行能源传输的通道，能够使能源、PLC数据输入能源路由器，或输出能源路由器，或者即能够输入也能够输出。在一些实施例中，PLC数据在能源网络中的传输与要传输、交互的能源使用相同的链路。
能源传输开关102，能够控制端口的开闭状态。在一些实施例中，根据能源流入或流出控制能源开关，导通当前能源路由器上位于传输路径上的端口，从而实现控制能源流向。在一些实施例中，当确定能源传输时，会收到来自其他能源路由器、控制端或路由处理器的PLC能源传输指令。当接收到PLC能源传输指令时，开启能源传输开关；接收到来自其他能源路由器、控制端或路由处理器的PLC能源传输完毕指令时，关闭能源传输开关。在一些实施例中，能源传输开关102的数量可以与端口相匹 配，每个能源传输开关控制一个端口的通断。
路由处理器103，能够根据PLC数据和存储的路由信息确定能源传输路径。在一些实施例中，路由处理器103能够根据PLC数据确定目的地址；根据存储的路由信息，基于最短路径算法确定能源传输路径，进而确定下一跳地址。在一些实施例中，路由处理器根据确定与能源传输路径相关联的对应端口，导通端口的能源传输开关，以便输入能源路由器的电能从导通的对应端口输出。
这样的能源路由器能够接收能源和PLC数据，根据PLC数据为能源规划传输路径，并导通传输路径上的端口供能源传输，使得能源能够在能源网络中的灵活传输，方便了电能的交易，提高了能源交互的灵活性。
在一些实施例中，路由处理器103包括能源路径存储单元和能源路径择优单元。能源路径存储单元能够存储系统网络内能源传输最短路径。新建能源传输路径时，直接存储到能源路径存储单元，后续新增能源传输路径且路径更短时，更新能源路径存储单元。能源路径择优单元从能源路径存储单元中选择最短的能源传输路径。这样的能源路由器在提高路径规划效率的同时，也不断优化传输路径，降低能源在传输过程中的损耗。
在一些实施例中，路由处理器103可以为处理器芯片，执行路由计算功能。在一些实施例中，路由处理器103可以通过FPGA(Field Programmable Gate Array，现场可编程逻辑门阵列)实现。
在一些实施例中，路由处理器103在根据存储的路由信息不能生成传输路径的情况下，通过端口向其他路由器发送广播信息，收到广播消息的能源路由器反馈自身存储的、与目的地址相关联的路由信息；根据更新后的路由信息确定能源传输路径。路由处理器103根据收到的路径反馈更新存储的路由信息，进而根据更新后的路由信息，基于最短路径算法确定能源传输路径，进而确定下一跳地址以及输出端口，导通端口的能源传输开关。
这样的能源路由器能够在自身网络拓扑不全的情况下，通过广播信息的方式从其他网络节点得到路由信息，进而补充自身存储的网络拓扑，提高能源传输路径规划成功的概率，以及提高能源传输效率。
在一些实施例中，如图1B所示，能源路由器还包括能源计量处理器104。能源计量处理器104能够统计各个端口的能源信息。在一些实施例中，能源计量处理器104计量各个端口流入或流出的电量。在一些实施例中，在能源传输时，在能源传输开关 从开到关的时间段内，将记录持续时间t，以传输时间段的均值功率p乘以时间t计算时间段内的电量，进而能够计量传输的能源。在一些实施例中，PLC数据中包括能源的目标地址、源地址、传输量以及实时电压电流功率等信息，基于能源计量处理器104对各个端口的统计结果，结合PLC数据中的信息实现对端到端能源传输的统计。在一些实施例中，能源计量处理器104可以为处理器芯片。在一些实施例中，能源计量处理器104可以通过FPGA实现。
在一些实施例中，如图1B所示，能源路由器还包括位于端口之间，执行交流变换或电压转换中至少一项功能的能源转换处理器105。由于能源路由器两端的电压、交直流情况不一定相同，因此需要进行能源转换，如400V转成48V等。在一些实施例中，能源转换处理器105实现交直流/高低压互相转换功能。在一些实施例中，能源转换处理器105为逆变器。在一些实施例中，能源转换处理器105可以为处理器芯片。在一些实施例中，能源转换处理器105可以通过FPGA实现。
这样的能源路由器能够考虑到能源传输网络两侧网络环境不同的问题，扩展了能源路由器的应用范围。
在一些实施例中，如图1B所示，能源路由器还包括跨电压转换处理器106。PLC数据在跨电压时面临电压耦合问题，即能源数据无法直接跨电压传输，在经过变压转换后，载波特征将消失，因此无法体现能源数据。在一些实施例中，通过增加电感，以电压耦合或电流耦合方式，在不同电压两侧，将能源数据桥接。这样的能源路由器能够避免跨电压造成的PLC数据丢失，保证能源网络数据传输的可靠性。在一些实施例中，跨电压转换处理器106可以为处理器芯片。在一些实施例中，跨电压转换处理器106可以通过FPGA实现。
在另一些实施例中，跨电压转换处理器106接收来自端口的PLC数据的报文，发送给路由处理器；将路由处理器生成的能源传输路径按照输出电压封装成PLC数据的报文。跨电压转换处理器106的输入端位于电能在能源路由器的输入端口与能源转换处理器105的输入端之间，跨电压转换处理器106的输出端位于电能在能源路由器的输出端口与能源转换处理器105的输出端之间，从而在电压转换的过程中将PLC数据剥离，避免数据丢失。在一些实施例中，根据需求对PLC数据进行处理，如生成新的源EIP地址、目标EIP地址，并附加到传输协议报文上，再以新的协议报文传输到另一侧电压，从而实现PLC数据的更新，提高了数据传输的灵活性。
在一些实施例中，如图1B所示，能源路由器还包括：数据处理器107，能够基 于应用层、传输层、网络层、链路层的架构划分形成能源信息通讯传输、能源互联网协议框架。在一些实施例中，数据处理器107可以为一个或多个处理器芯片。在一些实施例中，跨电压转换处理器106可以通过FPGA实现。

网络层子处理器，能够根据传输层数据包、MAC地址和EIP地址，生成网络层数据包，还能够解析来自链路层子处理器的网络层数据包。
链路层子处理器，能够根据网络层数据包生成PLC数据报文，还能够解析来自能源网络的PLC数据报文。
在实际传输能源数据过程中，将每层数据从上往下依次封装组成数据包，最终数据包将体现如图3所示的应用数据、源MAC地址、目标MAC地址、源EIP地址、目标EIP地址、协议类型、校验和等信息。在一些实施例中，上述每个子处理器可以为一个处理芯片，子处理器之间相互连接构成数据处理器。
这样的能源路由器借鉴IP网络层级架构，在数据生成、解析和传输过程中，通过如图2中所示的分层处理方式，保证数据传输的可行性和可靠性。

应用数据字段，根据需要包括能源数据、控制数据、状态数据或故障数据中的一 项或多项。
这样的数据报文形式能够与能源路由器的层级架构相配合，保证数据传输的可行性和可靠性，且提高数据传输内容的灵活度。
在一些实施例中，能源路由器通过互相之间的连接，以及与多个端节点之间的连接，构成如图4所示的能源网络。能源网络中包括多个端节点411～41m，m为正整数。在一些实施例中，端节点为发电厂节点或用户节点等，能够执行产生电能或消耗电能中的至少一项。能源网络中多个上文中提到的任意一种能源路由器401～40n，n为正整数。每个能源路由器与端节点和其他能源路由器中的至少两个节点连接，构成能源网络拓扑。
这样的能源网络中能够传输能源和PLC数据，能源路由器能够根据PLC数据为能源规划传输路径，并导通传输路径上的端口供能源传输，使得能源能够在能源网络中的灵活传输，方便了电能的交易，提高了能源交互的灵活性。
在一些实施例中，基于能源网络，能源交互方法的一些实施例的流程图如图5所示。
在步骤501中，能源输出端通过连接的能源路由器生成PLC数据。在一些实施例中，PLC数据中包括目的地址。PLC数据中还包括源地址、下一跳地址、能源交互数量等。
在步骤502中，收到PLC数据的能源路由器根据目的地址确定能源传输路径和下一跳地址，导通输入PLC数据的端口和与下一跳能源路由器地址相连接的端口，并将PLC数据发送至下一跳节点。
在步骤503中，下一跳节点在收到PLC数据后，判断自身是否为目的地址的节点。若为目的地址节点，则完成整条路径的规划，执行步骤504；若不为目的地址节点，则继续执行步骤502。
在步骤504中，根据能源路由器的导通路径执行电能传输。
在一些实施例中，PLC数据与要交互的电能同步传输，随着一个下一跳节点的确定导通一节电路，在到达目的节点后，电能到达目的节点。
在另一些实施例中，先传输PLC数据，在完成从源端到目的端的路径导通后执行电能传输。
通过这样方法，能够在能源网络中传输能源和PLC数据，能源路由器根据PLC数据为能源规划传输路径，并导通传输路径上的端口供能源传输，使得能源能够在能 源网络中的灵活传输，方便了电能的交易，提高了能源交互的灵活性。

在一些实施例中，能源路由器在交流变换和电压转换之前提取来自端口的PLC数据的报文后，提取报文中的应用数据，以便根据存储的路由信息确定能源传输路径；将应用数据重新封装成PLC数据的报文，通过能源输出的端口输出。通过这样的方法，能够在电压转换的过程中将PLC数据剥离，避免跨电压造成的PLC数据丢失，保证能源网络数据传输的可靠性；实现PLC数据的更新，提高了数据传输的灵活性。
