3. after receiving the command of changing the broadcasting personal area network ID, the routing slave (Router) temporarily sets itself as the broadcasting personal area network ID, and then broadcasts and transmits the broadcasting personal area network ID to the routing slaves (routers) of the surrounding non-identical network segments until all the routing slaves in the communication range are changed into the same local area network ID, namely the broadcasting personal area network ID, so that in the broadcasting local area network, the to-be-networked coordinator can communicate with the routing slaves in all the communication ranges to facilitate the subsequent work; each routing slave stores the original personal area network ID before receiving the broadcast information and changing the broadcast information into the broadcast personal area network ID;
4. at this time, the coordinator to be networked and all the routing slaves are in the same network, and the coordinator to be networked extracts the node device address and/or the father node device address of each routing slave from the messages of all the routing slaves responding by changing the broadcast personal area network ID, so as to identify the corresponding network topology;
5. according to the network topology structure, the coordinator to be networked autonomously judges the position of each routing slave, and modifies the channel and the personal area network ID of the designated route by far and near. Each routing slave machine judges according to the received modification instruction, and if the binding ID in the modification instruction is equal to the equipment ID of the routing slave machine, the personal local area network ID of the corresponding routing slave machine is changed into the original personal local area network ID of the coordinator to be networked before restarting after the preset time; if not, accumulating waiting time;
6. the coordinator to be networked judges that all appointed devices have received the message and completed modification according to the response message of the appointed route, and if the modification is not completed, the step 5 is repeated; if the modification is completed, recovering the coordinator to be networked into the original personal area network ID of the coordinator to be networked, starting to build the network of the coordinator to be networked, and waiting for the designated route design to be added into the network;

1. and scanning surrounding networks when power is on, storing the surrounding networks in a cache, and simultaneously storing personal local area network IDs of the surrounding networks, wherein the cache can be an internal nonvolatile memory, an external EEPROM, an external FLASH and other modules.
2. Temporarily modifying the personal area network ID into broadcasting personal area network ID, and broadcasting the personal area network ID to surrounding networks through a cross-network communication technology of a zstack protocol stack;
3. sending a modification instruction to the designated route, and receiving a response message to judge whether the corresponding designated route is modified;
4. receiving response messages of all appointed routes, recovering the response messages to the original personal area network ID and constructing a network;
5. after waiting for all the routing slaves to join the network, the process ends.

1. when receiving an instruction for changing the personal area network ID into the broadcasting personal area network ID, storing the original personal area network ID, changing the personal area network ID into the broadcasting personal area network ID, and adding the broadcasting personal area network ID into the broadcasting local area network;
2. receiving a modification instruction, judging whether the binding ID in the modification instruction is equal to the ID of the equipment, if so, modifying the ID of the personal area network of the equipment, restarting after a preset time, and adding the personal area network ID into a new network, namely a network to be networked;
3. if the binding ID in the modification instruction is judged to be unequal to the ID of the device, accumulating the waiting time, if the waiting time exceeds the pre-waiting time, changing the routing slave into the original personal area network ID of the routing slave, adding the original personal area network ID into the original network, and if the waiting time does not exceed the pre-waiting time, repeating the processes of 2 and 3.
According to the method, the modification instruction is sent according to the network topology structure, so that all routing slaves in the communication range of the coordinator to be networked can be guaranteed to receive the modification instruction; and the route slaves (routers) which do not receive the modification instruction are restored to the respective original Personal Area Network ID (PANID) while the specified route is modified by the modification instruction in the pre-waiting time so as to avoid affecting the normal communication of the original network.
