101、将完成配网所需的数据进行分包，在分包后的数据中选取多个包，获取所述多个包中数据的总长度；
配网信息发送端准备完成配网所需的数据，其中对数据进行分包可以包括多种分包方式，本实施例中不同于现有技术的是，本实施例中的分包模式并不是线性的分割成若干块，固定码率的传输；而是依照某一特定概率分布，本方案不明确指定使用哪一种概率分布，应依据使用情况进行选择，如高斯分布，均匀分布等。
另外本发明实施例中将完成配网所需的数据进行分包，包括：通过无码率抹除码的方式，将完成配网所需的数据进行分包。无码率抹除码有多种实现，本方案不明确指定使用哪一种实现，如卢比变换码，Raptors码等。
在分包后的数据中选取多个包，获取所述多个包中数据的总长度，包括：
依据预设概率分布的方法在分包后的数据中选取多个包，如高斯分布，均匀分布等；
相应的，在步骤101中获取所述多个包中数据的总长度，包括：
将所述多个包中的数据进行异或运算，获取所述多个包中数据的总长度。
102、对所述多个包的索引进行组播广播地址调制，得到组播目标地址；
在对多个包的索引进行组播广播地址调制之前，本发明实施例中首先建立并记录多个包的索引，例如，随机选取d个包，如[d(i),d(j),….d(k)]，同时记录随机选取的这d个包的索引，记为A，有A＝[i,j,….k],其中(i,j,k)把选取的d个包的索引A＝[i,j,…k]，传入组播广播地址调制模块。
上述步骤102中，对所述多个包的索引进行组播广播地址调制，得到组播目标地址，包括以下子步骤：
1021、遍历所述多个包的索引；
1022、对每一索引进行位移操作后与前一索引的结果进行累加，得到所述多个包的索引的结果；
1023、将所述多个包的索引的结果作为组播目标地址。
103、根据所述多个包中数据的总长度以及组播目标地址解析所述多个包中的数据，重复以上步骤，直到解析完配网所需的数据。
由于多个包中数据的总长度已知，且组播目标地址已知，可以直接根据数据的长度以及组播目标地址得到多个包中的数据。由于多个包中的数据并不是全部配网所需的数据，因此在以上步骤中重复操作，直到解析完配网所需的数据。
上述步骤103在执行过程红可以包括如下子步骤：
1031、还原每一组播包中的多个包的索引以及多个包中数据的总长度；
1032、比较每一组播包中的多个包的索引，以及将每一组播包中的多个包中数据的总长度进行异或操作；
1033、当异或操作结果为1时，解析所述多个包中的数据；
1034、重复以上步骤，直到解析完配网所需的数据。
本发明提供的配网方法，将完成配网所需的数据进行分包，在分包后的数据中选取多个包，获取所述多个包中数据的总长度，通过无码率抹除码的编码方案实现了数据分包；对所述多个包的索引进行组播广播地址调制，得到组播目标地址；根据所述多个包中数据的总长度以及组播目标地址解析所述多个包中的数据，重复以上步骤，直到解析完配网所需的数据。本发明将无码率抹除码的编码方案与组播地址调制和包长度调制进行整合，避免了在IoT设备端未正确接收数据时持续轮播所有数据，造成时间与资源的大量浪费的问题，优化了物联网设备在配网过程中的性能，避免冗余信息的发送，提高配网成功率，优化配网时间。
图2为本发明一实施例的配网方法的流程示意图，如图2所示，本发明实施例一提供的配网方法，包括：
201、将完成配网所需的数据进行分包，在分包后的数据中选取多个包，获取所述多个包中数据的总长度。
例如，如图3所示，配网信息的发送端，准备IoT设备端完成配网所需的数据M，并线性地把完成配网所需的数据M分为N(大于等于1的正整数)个包，N的值可以预先设定，本实施例中定义是根据编码空间的上限，实际中可选取小于等于28的自然数，包的索引即1～N。
依照某一特定的概率分布，随机生成正整数d，d应小于等于N。依照均匀概率分布在N个包中，随机选取d个包，如[d(i),d(j),….d(k)]，对这d个包进行异或运算，得到S，即S＝d(i)xor d(j)xor…d(k)，同时记录随机选取的这d个包的索引，记为A， 有A＝[i,j,….k],其中(i,j,k)属于1～N。例如图3中所示d个包的d1，d2，d3……dn，以及异或运算后的S中的s1，s2，s3，s4……sk，其中s1为d2和d3异或运算的结果，s2为d1和d3异或运算的结果，由于本实施例中采用喷泉码编码的方式，将配网信息发送端的数据进行随机得到N个包，为了方便理解，举例说明如下，d1中包括数据abc，d2中包括数据a，d3中包括数据d，那么s1为d2和d3异或运算的结果ad，s2为d1和d3异或运算的结果abcd，如果S中只包括s1和s2，那么S为s1和s2异或运算的结果abcd，数据长度为4。
无码率抹除码有多种实现，本方案不明确指定使用哪一种实现，如卢比变换码，Raptors码等，也可以如图3中所示的喷泉码编码的方式实现。
选取d个包时，依照某一特定概率分布，本方案不明确指定使用哪一种概率分布，应依据使用情况进行选择，如高斯分布，均匀分布等。
可理解的是，上述字母n、k、i、j等均为大于等于1的自然数，为了举例方便的示例说明，并不对其大小进行限定。
对所述多个包的索引进行组播广播地址调制，得到组播目标地址；
如图3中的组播地址调制，把选取的d个包的索引A＝[i,j,…k]，传入组播广播地址调制模块。遍历A，对于d个包中每一个包的索引a，进行位移操作(1<<a)后累加得到Q，有如下为代码来表示：
Q＝0
for a in A:
Q＝Q+(1<<a)
因为在A中的任意一个数a，都小于等于28且无重复，所以Q是一个(0x00～0x f ff ff ff)中的一个数，将Q表示为0x f:ff:ff:ff的形式，转换为十进制即为
Q的范围为(0:0:0:0～16:255:255:255)
最后对左第一位累加偏移224，故Q的范围是(224:0:0:0–255:255:255:255)，使用Q作为组播目标地址。
203、根据所述组播目标地址和所述多个包中数据的总长度，生成组播包。
如图3中的封包长度调制，生成组播包，使用包的长度来调制信息(因为在解码端，无法解包，无法获取包内的内容，所以使用包的长度来调制信息)，包的长度等于S。 发送这个组播包，目标地址为Q，包内容的长度为S。其中，多个包中数据的总长度携带有信息S。
204、根据组播包解析所述多个包中的数据，重复以上步骤，直到解析完配网所需的数据。
在图3中的数据解码器端，收到组播包，从组播的地址中，还原A，从组播包的长度中，还原S。数据解码器端不断的收到组播包，将收到各个组播包中的A进行比较，将收到各个组播包中的S进行异或xor操作，当异或操作的结果为d＝1时，即成功解析出一个数据分片d(i)。
发送端重复201，202，203步骤，生成并发送新的组播包。持续收取组播包，重复上述操作，直到解析出所有数据。
本方案采用无码率抹除码编码方案，并与组播地址调制与包长度调制进行整合，可极大的优化物联网设备在配网过程中的性能，避免冗余信息的发送，提高配网成功率，优化配网时间。
