在一实施例中，所述ARM核心处理器还设置为通过底板信号接口模块与主站相连接，设置为将所述台区设备的拓扑结构、相位、所属台区和地理位置信息上传至所述主站；其中，所述台区设备的个数为多个，所述台区设备的拓扑结构根据多个台区设备的所属台区生成，或所述台区设备的拓扑结构根据多个台区设备的相位以及所属台区生成；所述多个台区设备包括换相开关、分布式电源、充电桩和总表；所述载波通信模块的输出端设置为通过电力线接口模块分别与所述换相开关、所述分布式电源、所述充电桩和所述总表相连接；所述sub-G无线通信模块的输出端设置为通过天线模块分别与所述换相开关、所述分布式电源、所述充电桩和所述总表相连接，所述GPS模块的输出端设置为通过所述天线模块分别与所述换相开关、所述分布式电源、所述充电桩和所述总表相连接。
本申请采用的技术方案如图3所示，本申请采用ARM架构的微处理器，ARM处理器通过以太网连接宽带载波通信模块，载波通信模块通过电力线将调制的信号传递到对端实现点对多点通信；sub-G无线通信模块和ARM处理器使用串行外设接口(Serial Peripheral Interface，SPI)连接，并通过无线信号和其他模块组成PAN个域网；GPS模块和ARM处理器通过通用异步收发传输器(Universal Asynchronous Receiver/Transmitter，UART)接口连接，获取台区设备的地理位置信息；使用该技术方案设计出具有宽带载波通信能力，能够识别设备是否属于台区以及台区内设备相位的智能配变终端；GPS实现设备的地理位置定位，并通过sub-G无线通信将设备的相位、运行状态、故障信息、地理位置信息上送到调度系统，实现智能台区的精细化调控。
配变台区设备状态监控方法方法，包括以下步骤：
步骤10、配变终端每隔预设时间，通过载波通信模块对台区设备进行台区 识别和相位识别，获取所述台区设备的所属台区和相位。
在一实施例中，预设时间为15分钟。
低压电力线载波通信以台区变压器为单位，配合智能配变终端使用。在跨变压器台区的情况下，因为存在两个变压器的信号隔离衰减，不同台区的载波信号往往是不能通信成功的，因此可以根据智能配变终端是否能够成功接收到载波通信模块发送的数据来判定该台区设备是否属于该台区。
在一实施例中，步骤10包括以下之一：在通过载波通信模块输出端的A相电力线接收到所述台区设备发出的工频载波调制信号的情况下，确定所述台区设备和所述配变终端属于一个台区，且所述台区设备的所属相位为A相；在通过载波通信模块输出端的B相电力线接收到所述台区设备发出的工频载波调制信号的情况下，确定所述台区设备和所述配变终端属于一个台区，且所述台区设备的所属相位为B相；在通过载波通信模块输出端的C相电力线接收到所述台区设备发出的工频载波调制信号的情况下，确定所述台区设备和所述配变终端属于一个台区，且所述台区设备的所属相位为C相。
步骤20、配变终端通过宽带载波或者sub-G无线通信模块将所述台区设备的拓扑结构、相位、所属台区以及地理位置信息上传至调度系统。
在一实施例中，所述sub-G无线通信模块包括PAN协调器；所述sub-G无线通信模块通过如下方式建立网络：主PAN协调器将自身设置为一个簇标识符CID为0的簇头，其中，所述主PAN协调器为位于所述配变终端的PAN协调器；所述主PAN协调器选择一个当前建立的网络中没有使用的PAN标识符，并以广播的方式发送包含所述PAN标识符的信标帧，以使接收到所述信标帧的第一PAN协调器向所述主PAN协调器发送第一网络加入请求；其中，所述第一PAN协调器为位于所述台区设备的PAN协调器，所述第一网络加入请求中包括所述PAN标识符以及所述第一PAN协调器的识别信息；所述主协调器在接收到所述第一网络加入请求的情况下，判断以与所述PAN标识符相关联的第一PAN协调器形成的子网络是否满足预设条件；在所述子网络未满足所述预设条件的情况下，所述主PAN协调器允许所述第一PAN协调器加入当前建立的网络中，并将所述第一PAN协调器作为当前建立的网络中的网络结点加入到邻近表中；在所述子网络满足所述预设条件的情况下，所述主PAN协调器不允许所述第一PAN协调器加入当前建立的网络中，并指定所述第一PAN协调器为一个子主PAN协调器，作为一个新的簇头，将一个新的PAN标识符分配给所述子主PAN协调器，并设置所述子主PAN协调器的簇标识符CID为0以使所述子主PAN协调器以广播的方式发送包含所述新的PAN标识符的信标帧；其中，所述第二PAN协调器为位于台区设备中的协调器；在所述主PAN协调器 接收到所述子主PAN协调器发送的第二PAN协调器的第二网络加入请求的情况下，其中，所述第二网络加入请求中包括所述新的PAN标识符以及所述第二PAN协调器的识别信息，所述主PAN协调器指定所述第二PAN协调器为一个子主PAN协调器，作为一个新的簇头，并返回执行将一个新的PAN标识符分配给所述子主PAN协调器，并设置所述子主PAN协调器的簇标识符CID为0。
在子主PAN协调器接收到发送的第二PAN协调器的第二网络加入请求的情况下，子主PAN协调器判断以与所述新的PAN标识符相关联的第一PAN协调器形成的子网络是否满足预设条件；在该子网络未满足所述预设条件的情况下，所述子主PAN协调器允许所述第一PAN协调器加入当前建立的网络中，并通知主PAN协调器将所述子目标PAN协调器作为网络结点加入到邻近表中。
在本实施例中，以相同的PAN标识符相关联的第一PAN协调器形成的子网络为一簇网络。
在一实施例中，在主PAN协调器确定当前建立的网络满足指定条件的情况下，通知网络中的所有PAN协调器停止发送信标帧。如主PAN协调器在当前建立的网络满足带宽需求的情况下，通知网络中的所有PAN协调器停止发送信标帧，或主PAN协调器确定没有PAN协调器可加入当前建立的网络的情况下，通知网络中的所有PAN协调器停止发送信标帧。
Sub-G无线通信组网采用树簇拓扑结构，是点对点网络拓扑结构的一种应用形式，在树簇中配变终端作为全功能设备(Full Function Device，FFD)(全功能设备主协调器)，简化功能设备(Reduced Function Device，RFD)(分布式电源，充电桩，不平衡治理换相开关)作为一个叶结点连接在树簇拓扑结构树枝的末尾处。
在一实施例中，建立一个PAN(个域网)包括如下步骤：
110、PAN主协调器将自身设置为一个簇标识符(CID)为0的簇头。
120、选择一个没有使用的PAN标识符，并向邻近的其它设备以广播的方式发送信标帧，从而形成第一簇网络。
130、接收到信标帧的候选设备可以在簇头中请求加入该网络。
140、如果PAN主协调器允许该设备加入，那么主协调器会将该设备作为结点加入到邻近表中，成为该网络的一个从设备，同时，请求加入的设备将PAN协调器作为它的父结点加到邻近列表中，成为该网络的一个从设备，开始发送周期性的信标帧；其他的候选设备也可以在这台刚加入的设备上加入该网络。
150、如果接收到信标的节点不能加入到该网络中，那么它将寻找其它的父结点。最简单的网络结构是只有一个簇的网络，但是多数网络结构由多个相邻 的网络构成。一旦第一簇满足预定的应用或网络需求时，PAN主协调器将会指定一个从设备为另一簇新网络的簇头，使得该从设备成为另一个PAN的主协调器，随后其他的从设备将逐个加入，形成一个多簇网络。
如图3所示，图3中的直线表示设备间的父子关系而不是通信流。
在一实施例中，上述方法还包括以下至少之一：所述配变终端通过载波通信模块接收所述台区设备发送的所述台区设备的故障状态和地理位置信息所述配变终端通过第四代4G公网或者专网/以太网上报给主站，以使所述主站通知维修人员处理故障信息，或所述配变终端通过sub-G无线通信模块发送的所述台区设备的故障状态和地理位置位置，所述配变终端通过4G或者以太网上送主站，以使所述主站通知维修人员处理故障信息。
其中，在配变终端与台区设备之间的线路没有断电的情况下，台区设备已载波的形式发送该台区设备的故障状态和地理位置信息，如台区设备通过自身的载波通信模块向配变终端中的载波通信模块发送该台区设备的故障状态和地理位置信息；在配变终端与台区设备之间的线路断电的情况下，台区设备使用自身的备用电池，通过sub-G无线通信模块将故障状态和地理位置信息发送给配变终端。
本申请的工作原理是：
低压宽带载波通信技术较稳定成熟，且载波通信是以电力线网络为基础不需再架设通信通道，以及sub-G无线自组网的特点实现本申请的技术方案。
本申请通过宽带载波识别台区设备(包括总表、集中器、断路器、无功补偿电容装置、不平衡治理换相开关、分布式电源、充电桩)属于哪一相，当发生故障时宽带载波无法再工作，通过sub-G无线通信将故障点和地理位置信息上送到智能配变终端，配变终端通过4G或者以太网上送主台。
智能配变终端上行与主台之间可采用4G、以太网通信。智能配变终端下行设备采用RS485与低压宽带载波和sub-G无线等通信方式进行数据交互。
本申请是以智能配变终端为核心，主要通过低压宽带载波通信技术、sub-G无线通信技术以及GPS系统，整合周边设备以及台区到用户侧的设备，实现对整个台区的运行状态进行户变识别和地理位置识别，进而实现对台区二次设备的精细化智能化管控。
本申请采用Sub-G无线组网技术，增加网络通信的通信距离和通信可靠性。
本申请通过宽带载波，sub-G技术以及GPS定位，无需电表用户信息就可以实现台区下属设备识别，以及地理位置判别，生成设备的拓扑结构以及地理信息系统(Geographic Information System或Geo－Information system，GIS)地 理信息等，实现设备状态全管控。
本申请即便在所在地区已经发生停电故障的情况下，仍可以正常工作，提供故障精确地理位置和状态信息，实现信息和业务处理的在线化、透明化、智能化。
