具体实施方式
下面将结合附图对本申请实施方式作进一步地详细描述。
电力输电线、油气管线或河道等环境往往有监控需求。以电力输电线为例，需要在电力输电线的沿线布放多个节点，任意相邻的两个节点之间间隔一段距离。对于该多个节点中的任一个节点，该节点定期对该节点所在环境进行采集，将采集的数据定期发送给网管设备。网管设备能够接收到各节点发送的数据，基于各节点发送的数据实现对电力输电线的周边环境进行监控。
在电力输电线的沿线布放的多个节点往往呈链型分布。该多个节点采用多级级联组网方式形成链型网络，该链型网络中的节点包括头节点、尾节点以及位于头节点与尾节点之间的至少一个中间节点。
对于该链型网络中除头节点之外的任一个节点，该节点与该节点的上游邻居节点之间建立连接，该链型网络的头节点与网管设备通信。
该节点与该节点的上游邻居节点之间建立的连接有两种类型，该两种类型分别为如下第一类型和第二类型。
第一类型，该连接是无线连接。
该节点的上游邻居节点产生无线局域网，该节点接入该无线局域网，并通过该无线局域网与该节点的上游邻居节点建立无线连接。
例如，该节点的上游邻居节点产生wifi(可称为移动热点)网络，该节点接入该wifi网络，并通过该wifi网络与该节点的上游邻居节点建立wifi连接。
在该连接为无线连接时，该节点与该节点的上游邻居节点之间的位置关系满足指定条件。可选地，该指定条件包括如下一个或多个：该节点与该节点的上游邻居节点之间的距离小于距离阈值，或者，该节点与该节点的上游邻居节点之间的海拔差值小于差值阈值。
在该节点与该节点的上游邻居节点之间的位置关系满足指定条件时，该节点与该节点的上游邻居节点之间才能成功建立无线连接。例如，假设该无线连接为wifi连接，距离阈值为2km，在该节点与该节点的上游邻居节点之间的距离小于2km时，该节点与该节点的上游邻居节点之间才可能成功建立wifi连接。
第二类型，该节点与该节点的上游邻居节点之间存在物理链路，该连接是在该物理链路上建立的连接。
对于该链型网络中除头节点之外的任一个节点，该节点采集到数据后，向网管设备发送该数据。在实现时，该节点向该节点的上游邻居节点发送该数据。如果该上游邻居节点是头节点，则头节点向网管设备转发该数据，如果该上游邻居节点不是头节点，则该上游邻居节点向其自身的上游邻居节点发送该数据。对于该链型网络中的头节点，头节点采集到数据后，直接向网管设备发送该数据。所以该链型网络中除头节点之外的各节点的数据汇聚到头节点，由头节点向网管设备转发。
例如，以电力输电线的监控场景为例，用于架设电力输电线的多个电力塔通常是链型分布，可以在各电力塔上布放节点，在各电力塔上布放的节点组成链型网络。参见图1，假设该链型网络包括节点1、节点2、节点3，节点4和节点5，节点1为头节点并与网管设备通信，节点5为尾节点，节点5的上游邻居节点是节点4，节点5与节点4之间建立连接。节点4的上游邻居节点为节点3，节点4与节点3之间建立连接。节点3的上游邻居节点为节点2，节点3与节点2之间建立连接。节点2的上游邻居节点为节点1，节点2与节点1之间建立连接。
节点5对节点5所在环境进行采集，向节点4发送采集的数据。该数据经过节点4、节点3和节点2后被节点1接收到，节点1向网管设备发送该数据，网管设备接收该数据，基于该数据实现对节点5所在环境进行监控。节点4、节点3和节点2同节点5一样向网管设备发送数据，节点1可直接向网络设备发送数据。
参见图2，节点包括路由设备和传感器设备，传感器设备用于对该节点周边环境进行采集，路由设备用于向网管设备发送传感器设备采集的数据。对于链型网络中除头节点之外的节点，该节点包括的路由设备与该节点的上游邻居节点包括的路由设备之间建立连接。对于该节点的传感器设备采集的数据，该节点的路由设备通过该连接向该节点的上游邻居节点发送该数据。该上游邻居节点的路由设备接收该数据，再向网管设备的方向转发该数据。
在一些实施例中，参见图3，该节点的路由设备可能包括内置中继器(repeater，RT)和外置RT，该内置RT与传感器设备集成一起，该外置RT与该内置RT连接。可选地，该外置RT与该内置RT通过线缆相连，例如，该外置RT与该内置RT使用网线相连。
在一些实施例中，该节点的内置RT与该节点的上游邻居节点中的外置RT建立连接。在实现时，
该节点的上游邻居节点包括的外置RT产生无线局域网，该节点包括该无线局域网的网络信息，该节点的内置RT基于该无线局域网的网络信息接入该无线局域，并通过该无线局域网与该节点的上游邻居节点建立连接。
例如，该节点的上游邻居节点的外置RT产生的无线局域网为wifi网络，该wifi网络的网络信息包括wifi网络的名称和/或密码等信息。该节点包括该wifi网络的网络信息，该节点的内置RT基于该wifi网络的网络信息接入该wifi网络，并通过该wifi网络与该节点的上游邻居节点建立连接。
以图1所示的链型网络为例，图1所示的链型网络的节点1、节点2、节点3、节点4和节点5的结构为图3和图4所示的节点结构。节点5包括节点4的外置RT产生的wifi网络4的网络信息4，节点5的内置RT基于网络信息4接入wifi网络4，并通过wifi网 络4与节点4建立wifi连接4。节点4包括节点3的外置RT产生的wifi网络3的网络信息3，节点4的内置RT基于网络信息3接入wifi网络3，并通过wifi网络3与节点3建立wifi连接3。节点3包括节点2的外置RT产生的wifi网络2的网络信息2，节点3的内置RT基于网络信息2接入wifi网络2，并通过wifi网络2与节点2建立wifi连接2。节点2包括节点1的外置RT产生的wifi网络1的网络信息1，节点2的内置RT基于网络信息1接入wifi网络1，并通过wifi网络1与节点1建立wifi连接1。
在一些实施例中，节点的传感器设备为摄像头、温度传感器或湿度传感器等。摄像头采集的数据是对该节点中周边环境进行拍摄的图像或视频，温度传感器采集的数据是该节点周边环境的温度，湿度传感器采集的数据是该节点周边环境的湿度。网管设备为服务器或终端等设备。
其中，在第一网络发生故障时，可能会导致第一网络中的部分节点无法向网管设备发送数据，接下来对此情况进行详细说明。
在链型网络的相邻两个节点之间建立的连接为第一类型的连接(无线连接)时，对于链型网络中的某个节点，该节点的上游邻居节点是一个中间节点，在该节点与该节点的上游邻居节点之间的通信故障的情况下，如果该节点和该中间节点的上游邻居节点之间的位置关系不满足指定条件，该节点与该中间节点的上游邻居节点之间无法建立无线连接，这样该节点、尾节点以及位于该节点和尾节点之间的节点不能够继续向网管设备发送数据。其中，第一网络发生的故障为该节点与该节点的上游邻居节点之间的通信故障。
如果该节点和该中间节点的上游邻居节点之间的位置关系满足指定条件，该节点与该中间节点的上游邻居节点之间能够建立无线连接，这样该节点、尾节点以及位于该节点和尾节点之间的节点还能够继续向网管设备发送数据。
该节点与该节点的上游邻居节点之间的通信故障可能是该节点的上游邻居节点发生的故障或该节点与该节点的上游邻居节点通信的接口发生的故障。
例如，参见图1，假设节点2与节点3之间的通信故障，如果节点1与节点3之间的位置关系满足指定条件，则节点3与节点1建立无线连接。节点3、节点4和节点5还能够继续向网管设备发送数据。如果节点1与节点3之间的位置关系不满足指定条件，则节点3与节点1无法建立无线连接。节点3、节点4和节点5不能继续向网管设备发送数据，导致数据发送失败，通信中断，数据传输的可靠性低。
在链型网络的相邻两个节点之间建立的连接为第二类型的连接(在该两个节点之间的物理链路上建立的连接)时，在该节点与该节点的上游邻居节点之间的通信故障的情况下，该节点、尾节点以及位于该节点和尾节点之间的节点不能够继续向网管设备发送数据。
该节点与该节点的上游邻居节点之间的通信故障可能是该节点的上游邻居节点发生的故障，该节点与该节点的上游邻居节点之间的物理链路发生的故障或该节点与物理链路连接的接口发生的故障。
例如，参见图1，第一网络中的相邻两个节点之间使用物理链路相连，假设节点2与节点3之间的通信故障，节点3、节点4和节点5不能继续向网管设备发送数据，导致数据发送失败，能信中断，数据传输的可靠性低。
为了能够恢复通信，并提高数据传输的可靠性，参见图5，本申请实施例提供了一种网络架构500，该网络架构500包括第一网络501和第二网络502，第一网络501为链型网络。
第一网络501包括第一节点，第二网络502包括第二节点，第一节点和第二节点能够通信，第一节点是第一网络501中除头节点之外的节点。
其中，在第一网络501正常时，第一节点与第二节点之间的通信断开，在第一网络501故障时，且该故障导致第一节点与第一网络501的头节点之间的通信断开，第一节点与第二节点进行通信连接。
第一网络501的头节点与网管设备503通信。第二网络502包括汇聚节点，第二网络502中除汇聚节点之外的节点与该汇聚节点通信，该汇聚节点还与网管设备503通信。
电力输电线的沿线、油气管线的沿线或河道的沿线等监控场景分成第一区域和第二区域，第一网络501中的节点布放在该监控场景中的第一区域内，第一网络501中的节点对第一区域内的环境进行采集得到数据，且第一网络501中的节点采集得到的数据被汇聚到头节点，头节点向网管设备503转发该数据。
第二网络502中的节点布放在该监控场景中的第二区域内，第二网络502中的节点对第二区域内的环境进行采集得到数据，且第二网络502中的节点采集得到的数据被汇聚到汇聚节点，汇聚节点向网管设备503转发该数据。
参见图5，第一节点为第一网络501的尾节点，或者，参见图6，第一节点为第一网络501的头节点与尾节点之间的中间节点。
参见图5或图6，第二网络502为链型网络，第二节点为第二网络502的尾节点。或者，参见图7，第二节点为第二网络502的头节点与尾节点之间的中间节点。第二网络502的汇聚节点为第二网络502的头节点。
以电力输电线的场景为例，图5所示一种电力输电线示例，一条电力输电线被分成两段，其中一段的沿线布放第一网络501中的各节点，另一段的沿线布放第二网络502的各节点，在此场景下，第一节点可能为第一网络501的尾节点(节点5)，第二节点可能为第二网络502的尾节点(节点6)。
图6所示另一种电力输电线示例，两条电力输电线会交汇在一起。如图6所示，电力输电线1和电力输电线2交汇于A点，电力输电线1的沿线布放第一网络501中的各节点，电力输电线2的沿线布放第二网络502中的各节点。在此场景下，第一节点可能为第一网络501中的靠近A点的中间节点(节点4)，第二节点可能为第二网络502中的靠近A点的尾节点(节点6)。
图7所示另一种电力输电线示例，两条电力输电线会交叉。如图7所示，电力输电线1和电力输电线2交叉于A点，电力输电线1的沿线布放第一网络501中的各节点，电力输电线2的沿线布放第二网络502中的各节点。在此场景下，第一节点可能为第一网络501中的靠近A点的中间节点(节点4)，第二节点可能为第二网络502中的靠近A点的中间节点(节点7)。
参见图8，第二网络502为星型网络，第二网络502中除汇聚节点之外的节点与该汇聚节点通信，第二节点为该汇聚节点或者为第二网络502中除该汇聚节点之外的节点。
在第一网络501中的相邻两个节点之间的连接是第一类型的连接(无线连接)时，第一节点是第一网络501的指定节点与尾节点之间的中间节点，或者，第一节点是第一网络501的尾节点。
指定节点的下游邻居节点与指定节点的上游邻居节点之间的位置关系不满足指定条件。即指定节点的下游邻居节点与指定节点的上游邻居节点之间的距离大于或等于距离阈值，和/或，指定节点的下游邻居节点与指定节点的上游邻居节点之间的海拔差值大于或等于差值阈值。
在指定节点与指定节点的下游邻居节点之间的通信故障时，指定节点的下游邻居节点无法通过指定节点的上游邻居节点产生的无线局域网，与指定节点的上游邻居节点建立无线连接。如此使得位于指定节点与尾节点之间的中间节点无法向头节点发送数据，以及使得尾节点也无法向头节点发送数据。在此情况下，第一节点检测到该故障时，与第二节点进行通信连接，这样使得指定节点与尾节点之间的中间节点向第二网络发送数据，以及使得尾节点向第二网络发送数据，
例如，参见图5，第一网络501包括节点1、节点2、节点3、节点4和节点5，假设指定节点为节点2，节点2的上游邻居节点为节点1，节点2的下游邻居节点为节点3。节点1和节点3之间的距离大于或等于距离阈值，和/或，节点1和节点3之间的海拔差值大于或等于差值阈值。在节点2与节点3之间的通信故障时，节点3无法与节点1建立无线连接，为了在第一网络故障后，保证在节点2与节点3之间的通信故障时能够成功向网管设备503发送数据，第一节点为节点3、节点4或节点5。
在一些实施例中，第二节点用于产生无线局域网，第一节点包括该无线局域网的网络信息。第一节点基于该网络信息接入该无线局域网，并在该无线局域网中与第二节点之间建立无线连接，以实现了第一节点与第二节点进行通信连接。
在一些实施例中，第一网络501中的第一节点包括内置RT，第二网络502中的第二节点包括外置RT，第二节点的外置RT用于产生该无线局域网络，可以在第一节点中配置该无线局域网络的网络信息。在布放第一网络501中的第一节点和第二网络502中的第二节点时，使第一节点的内置RT基于该网络信息连接到第二节点，即在布放第一节点和第二节点时，测试第一节点是否能够连到第二节点。在第一成功连接到第二节点后，断开第一节点和第二节点之间的连接，第一网络501和第二网络502各自独立正常工作。
在第二网络502中的相邻两个节点之间的连接是第一类型的连接(无线连接)的情况，第二节点是第二网络502的指定节点与尾节点之间的中间节点，或者，第二节点是第二网络502的尾节点。
第二网络502的指定节点的含义与第一网络501的指定节点的含义相同，在此不再详细说明。
在第二网络502中的相邻两个节点之间的连接是第一类型的连接(无线连接)的情况，如果第二网络502故障，第二节点能够执行同第一节点一样的操作。第二节点与第一节点进行通信连接，并通过第一网络501向网管设备503发送数据，以恢复通信，提高数据传输的可靠性。
在一些实施例，第一节点包括外置RT，第二节点包括内置RT，第一节点的外置RT用 于产生无线局域网络，以及在第二节点中配置该无线局域网络的网络信息。在布放第一网络501中的第一节点和第二网络502中的第二节点时，使第二节点的内置RT基于该网络信息连接到第一节点，即在布放第一节点和第二节点时，测试第二节点是否能够连到第一节点。在第二节点成功连接到第一节点后断开第一节点和第二节点之间的连接，第一网络501和第二网络502各自独立正常工作。
在一些实施例中，第一节点与第二节点之间采用物理链路相连，在第一网络正常时，第一节点上与该物理链路相连的接口的接口状态为关闭状态。在第一网络故障时，第一节点将该接口的接口状态由关闭状态设置为打开状态，以在该物理链路上建立与第二节点之间的连接，即实现了第一节点与第二节点进行通信连接。
参见图9，本申请提供了一种通信方法900，所述方法900应用图5、图6或图7所示的网络架构500中，所述方法900包括如下步骤901-步骤903的流程。
步骤901：第一节点在检测到第一网络故障时与第二节点进行通信连接。
第一网络为链型网络，由于该故障，第一网络被分割成第一部分和第二部分，第一部分包括第一网络的头节点，第一部分与第二部分之间的通信断开，第二部分包括第一节点。
第一部分除头节点之外的节点还与头节点通信，第一部分除头节点之间的节点还可继续对该节点所在环境进行采集，并向该头节点发送采集的数据，头节点接收该数据，并向网管设备转发该数据。头节点还可继续对头节点所在环境进行采集，向网管设备发送该数据。
由于第一部分与第二部分之间的通信断开，也就是说第二部分中的每个节点与头节点之间的通信断开，第二部分中的每个节点无法向头节点发送数据。
第二部分中除第一节点之外的节点还与第一节点通信。
接下来列举了第一节点与第二节点采用如下方式一和方式二进行通信连接，当然第一节点和第二节点还可能采用其他方式进行通信连接，在此不再一一列举说明。
方式一、第二节点产生无线局域网，第一节点包括该无线局域网的网络信息。在步骤901中，第一节点在检测到第一网络故障时，获取第二节点的无线局域网的网络信息，基于该网络信息与第二节点进行通信连接。在实现时，
第一节点基于该网络信息接入该无线局域网，通过该无线局域网建立与第二节点之间的无线连接，以实现与第二节点进行通信连接。
在一些实施例中，该网络信息可能是管理员事先配置在第一节点上的。该网络信息可能包括该无线局域网的名称和/或密码等信息。
在方式一中，第一节点与第二节点之间的位置关系满足指定条件。该指定条件包括如下一个或多个：第一节点与第二节点之间的距离小于距离阈值，或者，第一节点与第二节点之间的海拔差值小于差值阈值。
在方式一中，第一节点中可能包括至少一个节点的无线局域网的网络信息，该至少一个节点为第二网络中的节点，且第一节点与该至少一个节点中的每个节点之间的位置关系均满足指定条件。可选地，第一节点可能从该至少一个节点中选择与第一节点之间的通信质量最好的一个节点作为第二节点，或者，第一节点可能从该至少一个节点中选择与第一 节点之间的通信质量超过质量阈值的一个节点作为第二节点，或者，第一节点可能从该至少一个节点中选择与第一节点之间的距离最短的一个节点作为第二节点。第一节点与第二节点进行通信连接。
例如，参见图5，第一网络包括节点1、节点2、节点3、节点4和节点5，节点1为第一网络的头节点，节点5为第一网络的尾节点，节点2、节点3和节点4为第一网络的中间节点。第二网络包括节点6、节点7和节点8，节点8为汇聚节点并与网管设备通信，节点6和节点7分别与节点8通信。
假设第一节点为第一网络的节点5，第二节点为第二网络的节点6。第一网络发生故障，该故障是节点2与节点3之间的通信故障。由于该故障，第一网络被分割为第一部分和第二部分，第一部分包括节点1和节点2，第二部分包括节点3、节点4和节点5，第一部分与第二部分之间的通信断开。第一部分中的节点2和节点1还能够向网管设备发送数据。
第一节点包括第二节点产生的无线局域网的网络信息，第一节点基于该网络信息接入该无线局域网，并通过该无线局域网与第二节点进行通信连接，这样第二部分中的节点3、节点4和节点5(第一节点)通过第二网络向网管设备发送数据。
方式二、第一节点与第二节点之间采用物理链路相连，第一节点与该物理链路相连的接口的接口状态为关闭状态。在步骤901中，第一节点在检测到第一网络故障时，将该接口的接口状态由关闭状态设置为打开状态，基于该物理链路与第二节点进行通信连接。在实现时，
第一节点在该物理链路上建立与第二节点之间的连接，以实现与第二节点进行通信连接。
例如，参见图5，第一网络的节点5与第二网络的节点6之间使用物理链路相连，节点5上与该物理链路相连的接口的状态为关闭状态。第一网络发生故障，该故障是节点2与节点3之间的通信故障。由于该故障，第一网络被分割为第一部分和第二部分，第一部分包括节点1和节点2，第二部分包括节点3、节点4和节点5。节点5将与该物理链路相连的接口的状态设置为打开状态，在该物理链路上与节点6进行通信连接，这样第二部分中的节点3、节点4和节点5通过第二网络向网管设备发送数据。
在一些实施例中，第二部分还包括第三节点，第一网络发生的故障是第三节点与第三节点的上游邻居节点之间的通信故障。在步骤901中，第一节点接收第一故障标识，第一故障标识是第三节点在检测到第一网络发生故障时发送的；基于第一故障标识确定第一网络发生故障。
第三节点和第三节点的上游邻居节点相互周期性地发送心跳报文。即第三节点周期性地接收第三节点的上游邻居节点发送的心跳报文，第三节点周期性地向第三节点的上游邻居节点发送心跳报文。在第三节点检测出没有接收到第三节点的上游邻居节点发送的心跳报文的时间长度达到时间长度阈值时，第三节点检测出第三节点与第三节点的上游邻居节点之间的通信发生了故障，向第二部分中除第三节点之外的节点发送第一故障标识。
第二部分中除第三节点之外的节点接收第一故障标识，基于第一故障标识确定第一网络发生故障。
在一些实施例中，第一故障标识用于指示第一网络发生的该故障的故障位置。可选地，第一故障标识包括第三节点的标识信息，第一故障标识用于指示该故障的故障位置位于第三节点与第三节点的上游邻居节点之间。第二部分中除第三节点之外的节点基于第一故障标识确定该故障位置。
该心跳报文可能为邻居组播报文等。
接下来列举了一种第三节点还向第二部分除第三节点之外的节点发送第一故障标识的示例，该示例为：
第三节点向第三节点的下游邻居节点发送第一心跳报文，第一心跳报文包括第一故障标识。该下游邻居节点接收第一心跳报文，向其下游邻居节点发送第二心跳报文，第二心跳报文包括第一故障标识。
例如，参见图5，节点3检测出未接收到节点2发送的第三心跳报文的时间长度达到时间长度阈值时，节点3检测出节点3与节点3的上游邻居节点(节点2)之间的通信发生了故障。其中，第二部分包括节点3、节点4和节点5，节点3向节点4发送第一心跳报文，第一心跳报文包括第一故障标识。节点4接收第一心跳报文，基于第一心跳报文中的第一故障标识确定第一网络发生了故障，向其下游邻居节点(节点5)发送第二心跳报文，第二心跳报文包括第一故障标识。节点5接收第二心跳报文，基于第二心跳报文中的第一故障标识确定第一网络发生了故障。
在一些实施例中，第一网络发生的故障是第一节点与第一节点的上游邻居节点之间的通信故障。
第一节点和第一节点的上游邻居节点相互周期性地发送心跳报文。即第一节点周期性地接收第一节点的上游邻居节点发送的心跳报文，第一节点周期性地向第一节点的上游邻居节点发送心跳报文。在第一节点检测出没有接收到第一节点的上游邻居节点发送的心跳报文的时间长度达到时间长度阈值时，第一节点检测出第一节点与第一节点的上游邻居节点之间的通信发生故障。
第二部分还包括除第一节点之外的节点，第一节点之外的节点与第一节点通信，第一节点还向第二部分除第一节点之外的节点发送第二故障标识，第二部分除第一节点之外的节点接收第二故障标识，基于第二故障标识检测出第一网络发生了故障。其中，第一节点向第二部分除第一节点之外的节点发送第二故障标识的过程，请参见上述第三节点向第二部分除第三节点之外的节点发送第一故障标识的过程，在此不再详细说明。
在一些实施例中，第二故障标识用于指示第一网络发生的该故障的故障位置。可选地，第二故障标识包括第一节点的标识信息，第二故障标识用于指示该故障的故障位置位于第一节点与第一节点的上游邻居节点之间。
在一些实施例中，在第一节点与第二节点进行通信连接后，第二部分中的节点还请求第二网络的汇聚节点分配地址，该节点基于该地址与第二网络中的汇聚节点进行通信，例如，该节点在向第二网络中的汇聚节点发送数据时，该节点的地址为该数据的源地址。
步骤902：第一节点向第二节点发送第一数据，第一数据是属于第二部分的数据。
在步骤902中，第一数据可能是第一节点的数据，第一数据可能包括第一节点对第一节点所在环境进行采集的数据，和/或，第一节点自身的数据。可选地，第一节点自身的 数据可能包括如下一个或多个：第一节点的位置、第一节点的设备属性数据、或者、第一节点产生的数据等。或者，
在步骤902中，第一数据是第一节点接收来自第二部分中除第一节点之外的节点发送的数据。
对于第二部分中除第一节点之外的任一个节点，为了便于说明，将该节点称为第四节点，第一数据可能是第四节点的数据，第一数据可能包括第四节点对第四节点所在环境进行采集的数据，和/或，第四节点自身的数据。可选地，第四节点自身的数据可能包括如下一个或多个：第四节点的位置、第四节点的设备属性数据、或者、第四节点产生的数据等。
对于第四节点，第四节点在接收到故障标识(第一故障标识或第二故障标识)时，基于该故障标识检测出第一网络发生故障以及该故障的故障位置，然后向第一节点发送第一数据。
如果第四节点位于该故障位置与第一节点之间，第四节点需要改变发送的数据方向，然后向第一节点发送第一数据。
其中，在第一网络发生故障前，第四节点的发送数据的方向为向第一网络的头节点发送数据的方向。在第一网络发生了故障，且第四节点位于该故障位置与第一节点之间时，第四节点将发送的数据方向改变为向第一节点发送数据的方向。
例如，参见图5，第一网络发生的故障为节点2与节点3之间的通信故障，第一节点为尾节点(节点5)，节点3和节点4为该故障的位置与节点5之间的节点，所以节点3和节点4在检测出第一网络发生故障后，将发送数据的方向由向第一网络的头节点(节点1)发送数据的方向改变为向第一网络的尾节点(节点5)发送数据的方向。
然后，节点3向节点4发送数据1，数据1为节点3采集的数据，节点4向节点5转发数据1，节点5再向第二网络的第二节点(节点6)转发数据1。同样，节点4向节点5发送数据2，数据2为节点4采集的数据，节点5向第二网络的第二节点(节点6)转发数据2，以及，节点5向第二网络的第二节点(节点6)发送数据3，数据3为节点6采集的数据。
步骤903：第二节点接收第一节点发送的第一数据，向网管设备发送第一数据。
由于第二节点与第二网络的汇聚节点通信，第二网络汇聚节点与网管设备通信。第二节点向第二网络的汇聚节点发送第一数据，第二网络的汇聚节点向网管设备发送第一数据。
例如，参见图5，在第一网络发生的故障后，第一节点(节点5)向第二节点(节点6)发送数据1、数据2和数据3。节点6接收数据1、数据2和数据3，向节点7发送数据1、数据2和数据3，节点7向节点8发送数据1、数据2和数据3，节点8再向网管设备发送数据1、数据2和数据3。
在第一网络发生故障后，可以对第一网络发生的故障进行维修，在第一网络恢复正常时，网管设备向第一节点发送恢复信息，该恢复信息用于指示第一网络的第一部分和第二部分之间的通信恢复正常。可选地，在实现时，
网管设备向第二网络汇聚节点发送恢复信息。第二网络的汇聚节点接收该恢复信息，向第二网络的第二节点发送该恢复信息。第二节点接收该恢复信息，向第一节点发送该恢 复信息。
其中，第一节点接收第二节点发送的恢复信息，基于该恢复信息断开与第二节点之间的通信连接，以及向第一网络的头节点发送第二数据，第二数据是属于第二部分的数据，第一数据和第二数据是第一节点在不同时刻得到的数据。
第一节点还向第二部分中除第一节点外的节点发送该恢复信息，对于位于第一网络发生的故障的故障位置与第一节点之间的节点，该节点接收该恢复信息后，改变发送的数据方向，然后向第一网络的头节点发送数据。
其中，该节点将发送数据的方向由向第一节点发送数据的方向改变为向第一网络的头节点发送数据的方向。
第二数据是第一节点的数据。或者，在第一节点是第一网络的中间节点时，第二数据可能是第一网络的尾节点发送的数据，或者，第二数据是第一节点与第一网络的尾节点之间的中间节点发送的数据。
在一些实施例中，在第一网络恢复正常时，第二部分中的节点请求还请求第一网络的头节点分配地址，该节点基于该地址与第一网络中的头节点进行通信，例如，该节点在向第一网络中的汇聚节点发送数据时，该节点的地址为该数据的源地址。
在本申请实施例中，第一网络中的第一节点与第二网络中的第二节点能够通信，在第一网络正常的情况下，第一节点与第二节点之间的通信断开，这样避免形成环形网络。在第一网络发生了故障的情况下，第一网络由该故障割成第一部分和第二部分，第一部分包括第一网络的头节点，第二部分包括第一节点，第一节点在检测到第一网络发生了故障时，与第二网络的第二节点进行通信连接，向第二节点发送第一数据，第一数据是第二部分的数据。第二节点再向网管设备发送第一数据，这样第二部分中的节点还能够继续发送数据，从而恢复了通信，提高数据传输的可靠性。
