Technical Field

The invention belongs to the technical field of photovoltaic monitoring and control technology, and particularly relates to a household wireless communication system without mutual interference and a networking method thereof.

Background

Along with the continuous expansion of the household photovoltaic market scale, the household power generation capacity is improved, the household power utilization safety problem is widely concerned, and the effect of the intelligent assembly is more and more prominent. Compared with the conventional assemblies, the intelligent assemblies have the advantages that the generated energy of each assembly can be monitored in real time, and the electrical connection among the assemblies can be timely disconnected to provide convenience for rescue when danger occurs. The intelligent components adopt a Zigbee wireless communication mode for data transmission, and how to prevent wireless crosstalk between two adjacent components has important significance on normal operation of the intelligent components. The household photovoltaic module has particularity, additional keys cannot be added, the requirement of automatically and automatically changing the network is met, and the normal operation of the adjacent network cannot be influenced while the network is changed.

Zigbee establishes networks by using ad hoc networks and dynamic routing and distinguishes each independent network by PANID (Personal area network ID). Currently, a ZigBee networking mode is to select a corresponding network to create or join a network by a key, or to select a time to join by a key, for example, a ZigBee networking module and a ZigBee networking method disclosed in chinese patent [ publication No.: CN106998562A ], which is a scheme that allows a device to join a Zigbee network by pressing a key for the number of times. For another example, a communication setting modification method for wireless communication networking [ publication No.: CN106162701A and CN ], although these two schemes avoid the use of extra keys and can modify the communication settings of the wireless communication networking, they only modify the same network and need to modify the personal area network ID and/or channel of all slaves in the same network, if there are more than two networks, the modification of the routing slaves in the adjacent network cannot be realized, otherwise the normal operation of the adjacent network will be affected.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The embodiment discloses a mutual noninterference user wireless communication method, which comprises a coordinator to be networked for establishing a network to be networked and a plurality of routing slave machines respectively positioned in the network to be networked and/or outside the network, and the specific method comprises the following steps:

1. powering on a Coordinator (Coordinator) to be networked, scanning surrounding networks, and storing network information and an ID (identity) of a personal area network of the Coordinator to be networked;

2. the method comprises the steps that a coordinator to be networked temporarily sets a personal area network ID (ID) of the coordinator to be a broadcast Personal Area Network ID (PANID), and sends a command for changing the broadcast personal area network ID to a surrounding network in a broadcast mode through an inter-PAN communication technology in a zstack protocol stack;

3. after receiving the command of changing the broadcast personal area network ID, the routing slave (Router) temporarily sets the Router to be the broadcast personal area network ID, and then broadcasts and sends the broadcast personal area network ID to the surrounding routing slave (Router) with a non-same network segment until all the routing slaves in the communication range are changed to be the same local area network ID, namely the broadcast personal area network ID, so that in the broadcast local area network, the coordinator to be networked can communicate with all the routing slaves in the communication range to facilitate subsequent work; each routing slave machine stores the original personal local area network ID before receiving the broadcast information and changing the broadcast information into the broadcast personal local area network ID;

4. at the moment, the coordinator to be networked and all the routing slave machines are in the same network, and the coordinator to be networked extracts the local node equipment address and/or the father node equipment address of each routing slave machine from the messages responded by all the routing slave machines through changing the broadcasting personal local area network ID so as to identify the corresponding network topological structure;

5. according to the network topology structure, the coordinator to be networked autonomously judges the position of each routing slave machine and modifies the channel of the designated routing and the personal area network ID from far to near. Each routing slave machine judges according to the received modification instruction, 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 to be the original personal local area network ID of the coordinator to be networked before restarting after preset time; if not, accumulating the waiting time;

6. the coordinator to be networked judges that all the specified devices receive the messages and complete modification according to the response messages of the specified routes, and if the modification is not completed, the step 5 is repeated; if the modification is finished, restoring the coordinator to be networked into the original personal area network ID, starting to build a network of the coordinator to be networked, and waiting for the designated routing design to join the network;

7. if the accumulated waiting time of the routing slave machines exceeds the pre-waiting time and no command for changing the personal local area network ID is received, the corresponding routing slave machines restore the personal local area network ID to be the original personal local area network ID so as to return to the original network, and the normal operation of the original network is not influenced.

The following describes the steps of the method from the perspective of the coordinator to be networked and the routing slave respectively:

as shown in fig. 1, the work flow of the coordinator to be networked is as follows:

1. when the power is on, the peripheral network is scanned and stored in the cache, and the personal area network ID of the user is stored at the same time, and the cache can be an internal nonvolatile memory, an external EEPROM, an external FLASH and other modules.

2. Temporarily modifying the self into a broadcast personal area network ID, and broadcasting the ID to a surrounding network 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 the designated routes, recovering the response messages into the ID of the original personal area network and establishing the network;

5. after waiting for all the routing slaves to join the network, the process ends.

As shown in fig. 2, the working flow of the routing slave is as follows:

1. if an instruction of changing into a broadcast personal area network ID is received, storing the original personal area network ID, changing the personal area network ID into the broadcast personal area network ID, and adding the personal area network ID into the broadcast local area network;

2. receiving a modification instruction, judging whether a 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 preset time, and adding the modified personal area network into a new network, namely the network to be networked;

3. if the binding ID in the modification instruction is judged not to be equal to the ID of the device, the waiting time is accumulated, if the waiting time exceeds the pre-waiting time, the routing slave machine is changed into the ID of the original personal local area network of the routing slave machine, the ID of the original personal local area network is added into the original network, and if the waiting time does not exceed the pre-waiting time, the processes 2 and 3 are repeated.

The method sends the modification instruction according to the network topology structure, and can ensure that all the routing slave machines in the communication range of the coordinator to be networked can receive the modification instruction; and when the route is appointed to receive the modification instruction to modify the personal local area network ID (PANID) within the pre-waiting time, the route slaves (routers) which do not receive the modification instruction are recovered to the respective original personal local area network ID (PANID) so as to avoid influencing the normal communication of the original network.

The following describes the present solution in detail with reference to specific examples:

in the initial state of the communication system, the original existing coordinator 1 has a personal area network ID of 0x1111, the existing routing slave 1 (having a personal area network ID of 0x2222), the routing slave 2 (having a personal area network ID of 0x1234), the routing slave 3 (having a personal area network ID of 0x5678), the routing slave 4 (having a personal area network ID of 0x1234) and the routing slave 5-8 having a personal area network ID of 0x1111 are newly added to the system, the coordinator 2 is the coordinator to be networked, and the personal area network ID is 0x2222, the connection relationship of the devices in the system is shown in fig. 3, the routing slave 5-8 is connected to the coordinator 1, the routing slave 1 is connected to the coordinator 2, and the routing slave 2-4 is not dependent on the local area network to which any coordinator host is located.

At this time, the routing slaves 1-4 are all added into the network where the coordinator 2 is located, and the steps are as follows: the coordinator 2 modifies itself to broadcast personal area network ID to 0x0001, and then broadcasts and sends the broadcast personal area network ID to the surrounding network through the cross-network communication technology of zstack protocol stack, so that the personal area network IDs of the surrounding routing slaves are all changed to broadcast personal area network ID (0x0001), as shown in fig. 4, at this time, in the broadcast local area network, the coordinator 2 and the routing slaves in all communication ranges can communicate.

Finally, the coordinator 2 sends a modification instruction to the designated routing slave 1-4 to modify the personal lan ID of the designated routing slave to 0x2222, and receives a response message that the modification is successful, after all the modifications are successful, the coordinator 2 changes the original personal lan ID (0x2222), the routing slave 5-8 which does not receive the modification instruction automatically changes the original personal lan ID (0x1111) after the pre-waiting time is over, at this time, the connection relationship in the system is as shown in fig. 5, the routing slave 5 is connected to the routing slave 8 on the coordinator 1, the routing slave 1 is connected to the routing slave 4 on the coordinator 2, and the modification process is completely over.
