Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention transmits the pre-generated configuration file to each gateway device in the same network, so that each gateway device generates corresponding sub-networks which are the same with each other according to the configuration file, thereby obtaining the total network composed of the sub-networks, and completes the construction of the network by allocating unique corresponding terminal device identification codes for each terminal device to be accessed in the coverage range of the total network.

The network expansion can be easily realized according to the same method, and the network coverage range of a plurality of terminal devices can be obtained under the condition of adding one gateway device, so that the network expansion efficiency is greatly increased. In addition, the invention manages the terminal equipment in the coverage range of the corresponding sub-network by introducing the gateway equipment, thereby realizing the distributed management of the terminal equipment in the network, reducing the influence among the terminal equipment and further improving the robustness of the network operation.
As shown in fig. 1, a schematic flow chart of a preferred embodiment of the network construction method provided by the present invention includes steps S11 to S12, which are specifically as follows:
s11: responding to a configuration file acquisition request of at least one gateway device, and sending a pre-stored configuration file to each gateway device so that each gateway device generates a corresponding sub-network according to the configuration file;
s12: and acquiring all the terminal equipment to be accessed in the coverage range of each sub network, and allocating a unique terminal equipment identification code to each terminal equipment to be accessed.
It should be noted that, the embodiment of the present invention is executed by a control module in a device, where the control module may be a control module in a certain gateway device, or may be a control module in another device, and is not limited herein. In the device where the control module is located, a configuration file corresponding to a network to be constructed or extended is stored in advance.
It is further noted that the network constructed or extended by the embodiments of the present invention is composed of one or more identical sub-networks.
In the process of network construction, when a certain gateway device needs to join in a network being constructed, the gateway device sends a configuration file acquisition request to the control module, and after receiving the configuration file acquisition request, the control module sends a configuration file pre-stored in local equipment to the gateway device. And after receiving the configuration file, the gateway device generates a corresponding sub-network according to the configuration file. Then, the control module responds to the device access instruction, obtains all the terminal devices to be accessed in the coverage range of the sub-network generated by the gateway device by controlling the gateway device, and allocates a unique corresponding terminal device identification code to each obtained terminal device to be accessed, so that the construction of the sub-network can be completed. When the number of the constructed sub-networks is one or more, the construction of the network can be completed. The device access instruction can be generated by a user by clicking a specific button or making a specific gesture, or can be generated by the control module autonomously.
In the same way, the expansion of the network can be done.
It should be further noted that the control module further includes a terminal device identification code recording table for recording each terminal device identification code assigned via the control module. When the control module allocates a terminal equipment identification code to a certain terminal equipment to be accessed, firstly generating a terminal equipment identification code, then judging whether the terminal equipment identification code is allocated to other terminal equipment by inquiring a terminal equipment identification code recording table, if so, regenerating a terminal equipment identification code, and carrying out the judgment again; if not, the identification code of the terminal equipment is distributed to the terminal equipment to be accessed. By using the terminal device identification code recording table, it is ensured that the terminal device identification codes assigned to the respective terminal devices by the same control module are different from one another.
Since the configuration file is generated and stored in advance, all the subnets generated according to the configuration file are identical to each other.
In some specific embodiments, the gateway device and the gateway device may be connected by a wired manner (e.g., Ethernet) or by a wireless manner (e.g., WiFi); the gateway equipment is connected with the terminal equipment in a Bluetooth mode.

The network expansion can be easily realized according to the same method, and the network coverage range of a plurality of terminal devices can be obtained under the condition of adding one gateway device, so that the network expansion efficiency is greatly increased. In addition, the gateway device is introduced to manage the terminal devices in the coverage range of the corresponding sub-network, so that the distributed management of the terminal devices in the network is realized, the influence among the terminal devices is reduced, and the robustness of the network operation is improved.
In another preferred embodiment, on the basis of the above embodiment, the configuration file includes a network identification code and a network key;

and generating the configuration file according to the network identification code and the network key, and storing the configuration file.

After the control module generates a corresponding configuration file according to the network identification code and the network key, the configuration file is stored in a storage medium (such as a flash) of the device where the configuration file is located.
Further, the gateway device includes a local gateway device and a non-local gateway device.
It should be noted that, in this embodiment, the control module is located in a certain gateway device, so that in a network construction process, the control module may send the configuration file to other non-local gateway devices, and may also send the configuration file to corresponding processing modules of a local gateway device according to a request of the local gateway device (i.e., the gateway device where the control module is located), so that both the local gateway device and the non-local gateway device can generate corresponding sub-networks according to the configuration file.
In some more preferred embodiments, after the user completes adding the first gateway device in the network to be constructed, the control module in the first gateway device randomly generates a network identifier and a network key, generates a corresponding configuration file according to the network identifier and the network key, and stores the configuration file in the flash of the first gateway device. The first gateway device generates a corresponding sub-network according to the configuration file. When the second gateway device accesses the network where the first gateway device is located, the control device of the first gateway device reads the configuration file from the flash and sends the configuration file to the second gateway device, so that the second gateway device generates a sub-network identical to the sub-network of the first gateway device according to the configuration file. According to the same method, the subsequent gateway devices can sequentially access to the network in which the first gateway device is located. Fig. 2 is a schematic diagram of a network constructed according to the present embodiment.
More preferably, the gateway device is a CSRmesh device.

and sending each terminal equipment identification code to the corresponding gateway equipment so that each gateway equipment sends and stores the received terminal equipment identification code to the corresponding terminal equipment to be accessed.
It should be noted that, after each gateway device generates a corresponding sub-network according to the configuration file, the control module sends a device scanning instruction to each gateway device, so that each gateway device scans all terminal devices in the coverage area of the corresponding sub-network, obtains all terminal devices to be accessed, and generates a corresponding device scanning result. And then, the control module combines and arranges the device scanning results returned by each gateway device, allocates a unique corresponding terminal device identification code for each terminal device to be accessed obtained by scanning according to each device scanning result, and sends each terminal device identification code to the corresponding terminal device to be accessed for storage through the corresponding gateway device, so that each terminal device to be accessed has a unique identity in the total network formed by the sub-networks.
