具体实施方式
以下将结合附图及实施例来详细说明本申请的实施方式，借此对本申请如何应用技术手段来解决技术问题，并达成技术效果的实现过程能充分理解并据以实施。需要说明的是，只要不构成冲突，本申请中的各个实施例以及各实施例中的各个特征可以相互结合，所形成的技术方案均在本申请的保护范围之内。
实施例一
为解决现有技术中存在的上述技术问题，本申请实施例提供了一种物联网设备的监控方法。
图1为本申请的物联网设备的监控方法一种实施例的流程图，如图1所示，本实施例的物联网设备的监控方法具体可以包括如下步骤：
100、获取构建的任意物联网设备组中存在的至少两个在线物联网设备中的每个在线物联网设备的设备信息；
在一个具体实施例中，物联网设备组的构建过程包括如下步骤：
步骤1，接收每个被监控物联网设备发送的设备集合。
本实施例中，每个被监控物联网设备发送的设备集合包括与该设备集合对应的被监控物联网设备和与所述每个被监控物联网设备能够相互匹配的其他被监控物联网设备。
具体地，因为每个被监控物联网设备之间是通过网络通讯模块进行连接的，所以我们要考虑以下因素：
第一、距离因素：两两网络通讯模块相互之间的连接有距离限制。例如，可以使用的网络通讯模块是无线保真(Wireless-Fidelity，WiFi)模块，两个WiFi模块之间的通讯最远距离为10米，这样如果两WiFi模块之间的距离小于10米，就认为两个通讯模块 可以相互连接，反之，如果两WiFi模块之间的距离大于或等于10米，则不能相互连接。因此，两个被监控物联网设备之间相互匹配的一个因素为两个设备使用的通讯模块之间的通讯距离小于所允许相互连接的最远距离。
第二、连接数目因素：网络通讯模块在考虑到其网络通讯能力和效率的情况下，网络通讯模块往往是有最大连接数的限制。例如，本实施例使用的网络通讯模块是WiFi模块，WiFi模块最大连接数为5，被控物联网设备A-D皆满足距离因素中对距离的要求，被控物联网设备A-D的链接信息如表1：
表1
被控物联网设备 A B C D
已有连接数 0 3 4 5
空闲连接数 5 2 1 0
根据上述假设可知：
A可以与B建立连接，因为A与B连接后，A的已有连接数为1，B的已有连接数为4，他们的已有连接数均不超过5。
A可以与C建立连接，理由同上。
B可以与C建立连接，理由同上。
A不可以与D建立连接，因为D的已有连接数是5，如果与其它的设备建立连接，5+1＞5，将超过最大连接数5。
既然A可以与B建立连接，A也可以与C建立连接，B也可以同C建立连接，那么A，B，C是否可以组成一个组呢？
不可以，因为，C只剩下1条空闲连接，只能和B、C中的一个建立连接，无法同时和B、C同时建立。
所以根据上述举例，租赁设备之相互匹配在连接数目因素需要满足以下条件：
a、当前设备的建立的连接数小于通讯模块的最大连接数；
b、一个组的设备数小于单个设备所能连接其它设备的最大值(最大连接数)。因为当一个组内的设备数大于单个设备所能连接其它设备的最大值时，就会出现举例中A、B、C不能同时建立连接的情况，所以为了避免出现该情况就直接给组内设备数的大小进行限制，由于此时还没有建立分组，所以该约束是对建立分组时的约束。
本实施例中，综合考虑上述因素后，可以得到与每个被监控物联网设备相对应的设备集合。例如，网络通讯模块能够建立的最大连接数为3，共5个被控物联网设备A1-E1，A1能与B1，C1，D1建立连接；B1能与C1,D1,E1建立连接；C1能与A1，E1，D1建立连接；D1能与A1，B1，E1建立连接，E1能与A1，C1，D1建立连接。那么，本实施例得到 的对于A1、B1、C1、D1、E1的S i的集合(集合包含设备本身)如下：
S A1＝{A1,B1,C1,D1}；S B1＝{B1,C1,D1,E1}；S C1＝{C1,A1,D1,E1}；S D1＝{D1,A1,B1,E1}；S E1＝{E1,A1,C1,D1}。
步骤2，根据预设的分组规则，对与每个被监控物联网设备对应的设备集合进行处理，将所有被监控物联网设备划分为一个或多个物联网设备组。
具体地，可以根据预设的每个物联网设备组中的最大设备数目M，依次选取包含M个设备的集合，得到与包含M个设备的集合相对应的交集，直到遍历所有集合；选取满足分组条件的交集后，并根据不重复分组原则，得到一个或多个物联网设备组；其中，满足分组条件为：与包含M个设备的集合相对应的交集包括M个设备的集合所对应的被监控物联网设备。M为大于等于2的整数。
例如，一个物联网设备组内最多分配两个物联网设备，可以获得如下结果：
S A1∩S B1＝{B1,C1,D1}不包含A1，所以不满足分组条件。
S A1∩S C1＝{A1,C1,D1}同时包含A1、C1，所以满足分组条件。
S A1∩S D1＝{A1,D1,B1}同时包含A1、D1，所以满足分组条件。
S A1∩S E1＝{A1,C1,D1}不包含E1，所以不满足分组条件。
S B1∩S C1＝{C1,D1,E1}不包含B1，所以不满足分组条件。
S B1∩S D1＝{B1,D1,E1}同时包含B1、D1，所以满足分组条件。
S B1∩S E1＝{C1,D1,E1}不包含B1，所以不满足分组条件。
S C1∩S D1＝{A1,D1,E1}不包含C1，所以不满足分组条件。
S C1∩S E1＝{A1,C1,D1,E1}同时包含C1、E1，所以满足分组条件。
S D1∩S E1＝{A1,D1,E1}同时包含D1、E1，所以满足分组条件。
由此可知，本实施例可以选择S A1∩S C1＝{A1,C1,D1}，S A1∩S D1＝{A1,D1,B1}，S B1∩S D1＝{B1,D1,E1}，S C1∩S E1＝{A1,C1,D1,E1}，S D1∩S E1＝{A1,D1,E1}。并构建的分组为A1C1、B1D1、E1，或者A1D1、C1E1、B1等，在此不再一一举例说明。本实施例中，具体如何分组可以由相关人员设定分组规则，从而得到N个物联网设备组。
在一个具体实现过程中，在将所有被监控物联网设备进行分组后，若每个任意物联网设备组中存在多个在线物联网设备，可以获取每个在线物联网设备的设备信息，如在线物联网设备的标号(设备1，设备2……)和/或在线物联网设备的入网时间(8：00am、9：am……)。
需要说明的是，本实施例中，若构建的任意物联网设备组中存在一个在线物联网设备，则按照相关技术的方式检测在线物联网设备是否异常离线即可。
101、根据每个在线物联网设备的设备信息，生成组环信息。
本实施例中，可以按照在线物联网设备的标号和/或在线物联网设备的入网时间进行排序，将排序结果作为组环信息。
102、将所述组环信息发送给多个在线物联网设备，以使多个在线物联网设备根据所述组环信息生成在线物联网设备环。
在得到组环信息后，可以将所述组环信息发送给多个在线物联网设备，以使多个在线物联网设备根据所述组环信息生成在线物联网设备环。
具体地，每个在线物联网设备分别接收服务器发送的组环信息后，即可知道其上游在线物联网设备的设备信息和下游在线物联网设备的设备信息，并实现将排好序的在线物联网设备环首尾相连组成的循环连接。例如，包括在线物联网设备A2、B2和C2，则可以组成这样一个在线物联网设备环：B2只向A2发送消息；A2只向C2发送消息，C2只向B2发送消息。如果只有A2、B2，则A2向B2发送消息，B2向A2发送消息，形成一个循环。
103、若接收到所述在线物联网设备环中任意在线物联网设备发送的存在离线设备的通知，向所述在线物联网设备环中每个在线物联网设备发送离线检测数据。
在每个在线物联网设备根据接收的组环信息生成在线物联网设备环后，在线物联网设备环中的在线物联网设备不停地循环发送数据包，以在环内监测在线物联网设备的状态。例如，若其中一个在线物联网设备在达到设定时长时，未接收到上游在线物联网设备发送的数据包，则认为上游在线物联网设备离线。此时，可以生成存在离线设备的通知，并发送给服务器，服务器若接收到所述在线物联网设备环中任意在线物联网设备发送的存在离线设备的通知，为了准确分析哪个在线物联网设备因为异常出现离线现象，可以向所述在线物联网设备环中每个在线物联网设备发送离线检测数据。
104、根据与所述离线检测数据相对应的响应数据，确定所述在线物联网设备环中的实际离线物联网设备。
本实施例中，在向所述在线物联网设备环中每个在线物联网设备发送离线检测数据后，实际在线物联网设备可以返回与所述离线检测数据相对应的响应数据，而实际离线物联网设备则无法返回与所述离线检测数据相对应的响应数据，进而可以确定所述在线物联网设备环中的实际离线物联网设备。
本实施例的物联网设备的监控方法，对构建的任意物联网设备组中存在的多个在线物联网设备，获取每个在线物联网设备的设备信息；根据每个在线物联网设备的设备信息，生成组环信息；将所述组环信息发送给所述多个在线物联网设备，以使所述多个在线物联网设备根据所述组环信息生成在线物联网设备环；若接收到所述在线物联网设备环中任意在线物联网设备发送的存在离线设备的通知，向所述在线物联网设备环中每个在线物联网设备发送离线检测数据；根据与所述离线检测数据相对应的响应数据，确定所述在线物联 网设备环中的实际离线物联网设备，实现了在线物联网设备环的中断状态下，对实际离线物联网设备的检测。无需每个在线物联网设备一直发送心跳包来检测物联网设备是否异常离线，有效防止服务器因收到大量信息造成网络拥堵、服务器占用资源大等造成不良状况，采用本申请的技术方案，能够提高检验效率。
进一步地，上述实施例中，还可以根据每个在线物联网设备针对所述离线检测数据的响应数据，确定所述在线物联网设备环中的实际在线物联网设备；若所述实际在线物联网设备的数目至少为两个，根据所述实际在线物联网设备的设备信息，生成离线重新组环信息；将所述离线重新组环信息和所述实际离线物联网设备的设备信息发送给所述实际在线物联网设备，以便所述实际在线物联网设备根据所述实际离线物联网设备的设备信息剔除所述实际离线物联网设备后，根据所述离线重新组环信息重新组环。其中，离线重新组环信息是因为存在异常离线的物联网设备而生成的重新组环信息。
在一个具体实施过程中，在线物联网设备环中任意在线物联网设备可能会因为操作人员的操作，正常离线，此时，在线物联网设备环中待离线物联网设备会发送离线请求，这样，若接收到所述在线物联网设备环中待离线物联网设备发送的离线请求，根据所述离线请求对应的待离线物联网设备的设备信息，确定所述在线物联网设备环中的实际在线物联网设备，即此时因为是正常离线，离线请求携带相关待离线物联网设备的设备信息，则可以直接确定哪个在线物联网设备发送的离线请求，从而可以确定所述在线物联网设备环中的实际在线物联网设备。本实施例中，若所述实际在线物联网设备的数目至少为两个，根据所述实际在线物联网设备的设备信息，生成离线重新组环信息；将所述离线重新组环信息和所述离线请求对应的待离线物联网设备的设备信息发送给所述实际在线物联网设备，以便所述实际在线物联网设备根据所述离线请求对应的待离线物联网设备的设备信息，剔除所述离线请求对应的待离线物联网设备后，根据所述离线重新组环信息重新组环。
在实际应用中，服务器可能接收到任意被监控物联网设备发送的上线请求，这样，可以根据待上线被监控物联网设备的设备信息，确定待上线被监控物联网设备所属的物联网设备组，并将待上线被监控物联网设备转化为在线物联网设备；若待上线被监控物联网设备所属的物联网设备组存在多个在线物联网设备，根据多个在线物联网设备的设备信息，生成扩增重新组环信息，以便多个在线物联网设备，根据所述扩增重新组环信息重新组环。其中，扩增重新组环信息表示其他被监控物联网设备需要上线生成的重组信息。具体地，因为其他被监控物联网设备需要上线，此时，可以将需要上线的其他被监控物联网设备加入原有的在线物联网设备环，此时可以生成扩增重新组环信息，并完成在线物联网设备环的重新组环。
在实际应用中，若因为大规模停电等因素，可能会导致在线物联网设备环中所有在线 物联网设备异常离线，此时，没有在线物联网设备向服务器告知有物联网设备异常离线了，服务器不知道有物联网设备发生了离线，因此，本实施例中，在生成在线物联网设备环后，从中随机选取一个在线物联网设备作为起始在线物联网设备，并由起始在线物联网设备周期性地向服务器发送状态上报数据。例如，在线物联网设备环未发生中断，且完成环内数据循环的次数达到3次后，由起始在线物联网设备向服务器发送状态上报数据，若服务器未接收到所述在线物联网设备环中起始在线物联网设备发送的状态上报数据，且未接收到所述存在离线设备的通知，确定所述在线物联网设备环中所有在线物联网设备转化为离线物联网设备。
例如，可以根据在线物联网设备环未发生中断，且完成环内数据循环的次数达到3次所需的时间，设定服务器接收起始在线物联网设备发送的状态上报数据的检测周期，若检测周期超过检测周期对应的阈值，仍未接收到所述在线物联网设备环中起始在线物联网设备发送的状态上报数据，且未接收到所述存在离线设备的通知，则可以确定所述在线物联网设备环中所有在线物联网设备转化为离线物联网设备。
本实施例中，构建了N个物联网设备组，在相关技术中每个物联网设备组未形成物联网设备环的情况下，由单个的物联网设备向服务器发送状态上报数据，在本申请的实施例的形成物联网设备环的情况下，由起始在线物联网设备发送的状态上报数据，相对相关技术的监控方法中，所有在线物联网设备发送的状态上报数据而言，数据量会小很多，服务器接收的信息量相对较少，从而不易造成网络拥堵、服务器占用资源较小，提高检验效率。
例如，有100个物联网设备，80个物联网设备在线，传统发包，单位时间内需要发送80个心跳包，而本申请假设100个物联网设备分为10个组，那么假设80个物联网设备在线，在线物联网设备分布在其中9个组，每个组单位时间内就发1个包，那么这80个物联网设备发包也就单位时间内发送了9个包，远远小于传统的80个包。
需要说明的是，本申请实施例的方法可以由单个设备执行，例如一台计算机或服务器等。本实施例的方法也可以应用于分布式场景下，由多台设备相互配合来完成。在这种分布式场景的情况下，这多台设备中的一台设备可以只执行本申请实施例的方法中的某一个或多个步骤，这多台设备相互之间会进行交互以完成的方法。
实施例二
为解决现有技术中存在的上述技术问题，本申请实施例提供了一种物联网设备的监控方法。
图2为本申请的物联网设备的监控方法另一实施例的流程图，如图2所示，本实施例的物联网设备的监控方法具体可以包括如下步骤：
200、构建的任意物联网设备组中的每个在线物联网设备分别接收服务器发送的组环信息；
201、每个在线物联网设备根据所述组环信息生成在线物联网设备环；
202、在线物联网设备环中任意在线物联网设备检测与其相邻的在线物联网设备之间断开连接时，生成存在离线设备的通知；
203、任意在线物联网设备将所述存在离线设备的通知发送给所述服务器。
本实施例中，服务器若接收到所述在线物联网设备环中任意在线物联网设备发送的存在离线设备的通知，向所述在线物联网设备环中每个在线物联网设备发送离线检测数据；根据与所述离线检测数据相对应的响应数据，确定所述在线物联网设备环中的实际离线物联网设备。
