[0002] Current power line communications and wireless communications require a central coordination node to open the network when the system is networked, allowing any nearby device to join the current network. Not only can you add devices within the home, you may also add devices from nearby neighbors, and you may even add malicious devices, causing interference or damage to the original network. Therefore, traditional networking methods have security risks.

[0003] In the current power line communication and wireless communication, during the system networking process, the central coordination node needs to frequently communicate with the added smart devices, including address information transmission and permission verification. When the number of devices is large, the networking process is very time-consuming and inefficient. If there are too many devices nearby, various interference information will appear, and even multiple networking failures may occur.

[0032] The concept of smart home appeared very early. Its core is to connect various devices in the home through the Internet of Things technology, providing a variety of functions and means such as home appliance control, lighting control, remote control, indoor and outdoor remote control, anti-theft alarm, environmental monitoring, and programmable timing control. Under the influence of the concept of IoT, the concept of smart home has been mentioned repeatedly. Almost all technology manufacturers are taking IoT and smart home as one of their future strategic development directions.

[0033] In the early stages of the development of the smart home industry, whole-house smart solutions mainly focused on pre-installation markets such as hotels and office buildings. Since they were deployed in advance, the equipment in each space in the building was relatively fixed, and there were high requirements for system stability. Therefore, wired connections were generally used to deploy whole-house intelligence. However, once the wired whole-house intelligence is deployed, the cost of changing it is high, which is basically equivalent to redecorating. In order to improve the flexibility of the whole-house smart solution and better respond to after-sales needs, the importance of wireless solutions in whole-house intelligence has soared. The advantages of wireless communication are low cost, high flexibility, strong scalability, and support for after-sales, allowing the whole-house intelligence to be adjusted according to the development of the times and changes in user needs. At present, the mainstream wireless communications for whole-house intelligence include ZigBee, Bluetooth, Thread, and Star Flash.

[0034] With the rapid development of Internet of Things technology, smart home communication technology is developing in the direction of diversification, modularization, intelligence and networking. Among them, PLC (Power Line Communication) technology, as a wired communication technology, transmits data through existing power supply lines without additional wiring. It has the characteristics of penetrating walls, not being affected by metal shielding, and easy deployment. It realizes the convenience of "communication as long as there are wires", so that PLC technology can achieve stable and reliable communication and linkage control between devices in the application of whole-house smart scenes. At present, the mainstream PLC communication technology for whole-house intelligence is defined by IEEE 1901.1.

[0035] In recent years, with the development of technology, the dual-network integration system of wired communication + wireless communication has begun to become the best technical solution. The two networks complement each other, realize the reliable connection of various devices, and ensure the high stability and high reliability transmission of control signals and data content, which is a technological innovation in the industry.

[0036] like Figure 8 As shown, the present invention provides a networking method for power line communication and wireless communication devices, comprising:

[0037] S1, the gateway device starts after being powered on, and after receiving the approach signal of the sub-device, reads the hardware unique identifier device model of the sub-device through the short-range wireless communication module;

[0038] S2, if the sub-device is a wireless communication device, assigning wireless address information to the sub-device, and writing the wireless address information into the sub-device through the short-range wireless communication module, wherein the wireless address information includes an application address, a network short address, a network number and a channel assigned by the system;

[0039] S3, if the sub-device is a power line communication device, assigning power line address information to the sub-device, adding the hardware unique identifier of the sub-device to the network whitelist of the power line communication module, and writing the power line address information to the sub-device through the short-range wireless communication module, wherein the power line address information includes an application address and a network number assigned by the system;

[0040] S4, after all sub-devices are written with networking information, the sub-devices are powered on and started, and after the wireless communication module or power line communication module of the sub-device is started, the networking information corresponding to the sub-device stored in the short-range wireless communication module is read (the networking information includes the application address, network short address, network number and channel, etc. assigned by the system) and a request is made to access the network;

[0041] S5, after confirming that the sub-device has successfully accessed the network, the sub-device saves its networking information to a storage medium (saves the networking information to the sub-device's own storage medium).

[0042] It also includes network selection, the gateway device is provided with a touch screen and / or physical buttons, and the network selection includes selecting the network to be connected to the sub-device through the touch screen and / or physical buttons. When the network selection fails (if no suitable network is found, it means that the network selection fails, and the search for a network that can be joined will continue) or when the network selection is skipped, the first matching network will be connected.

[0043] The number of the sub-devices to be connected to the network this time is at least one. After the sub-device writes the networking information, a successful network connection reminder is generated.

[0044] like Figure 6 As shown, the specific process S101 of wireless communication device networking and single-channel power line communication device networking is described in detail as follows:

[0045] 1. Power on and start the gateway device, and wait for the slave device to approach;

[0046] 2. Bring the sub-device and the gateway device close together, and the gateway device reads the MAC address (hardware unique identifier, also known as MAC) and device model of the sub-device through the short-range wireless communication module;

[0047] 3. If it is a wireless communication device, the application address and network short address are assigned. Then the application address, network short address, network N ID (also called network number), channel and other information assigned by the system are written into the sub-device module through the short-range wireless communication module;

[0048] 4. If it is a power line communication device, assign an application address. Add the MAC address of the sub-device to the network whitelist of the power line communication module. Then write the application address, network N ID and other information assigned by the system into the module of the sub-device through the short-range wireless communication module (the module of the sub-device is usually the short-range wireless communication module in the sub-device);

[0049] 5. After writing successfully, the buzzer or display screen will prompt whether the writing is successful. You can also use the mobile phone App to view the operation results. The mobile phone App is an optional auxiliary viewing method;

[0050] 6. Loop through steps 2 to 5 until all sub-devices have written networking information (writing networking information usually includes steps 2-5);

[0051] 7. Power on all sub-devices. After the wireless communication module or power line communication module in the sub-device is started, the application address, network short address, network N id and channel and other networking information stored in the short-range wireless communication module are read to request access to the network;

[0052] 8. After successfully joining the network, the wireless communication module or power line communication module in the sub-device writes the networking information such as the application address, network short address, network N id and channel into the storage medium (the storage medium here usually refers to the storage medium in the communication module, which is a small computer system with a computing unit, a storage unit, a communication unit, etc.) for the subsequent networking process. The subsequent networking process will directly read the data in the storage medium and no longer read the data in the short-range wireless communication module.

[0053] like Figure 7 As shown, the specific process S102 of networking of multiple power line communication devices is described in detail as follows:

[0054] 1. Power on the gateway device and start it. Select the network that the devices in this batch will join through the touch screen or buttons, and wait for the child devices to approach.

[0055] 2. Bring the sub-device and the gateway device close together, and the gateway reads the MAC address and device model of the sub-device through the short-range wireless communication module;

[0056] 3. Assign application address. Add the MAC address of the sub-device to the network whitelist of the power line communication module. Then write the application address, network N ID and other information assigned by the system into the sub-device module through the short-range wireless communication module;

[0057] 4. After the writing is successful, the buzzer or display screen (the buzzer or display screen on the gateway device) will prompt whether the writing is successful. You can also use the mobile app to view the operation results. The mobile app is an optional auxiliary viewing method;

[0058] 5. Repeat steps 2 to 4 until all devices in this batch have their networking information written into them;

[0059] 6. Power on all sub-devices and start them. After the power line communication module in the sub-device is started, the application address, network N id and other networking information stored in the short-range wireless communication module are read to request access to the network;

[0060] 7. After successfully joining the network, the power line communication module in the sub-device writes the application address, network N id and other networking information into the storage medium for subsequent networking processes. The subsequent networking process will directly read the data in the storage medium and no longer read the data in the short-range wireless communication module.

[0061] The program modules of the gateway device are as follows Figure 1 , 2 , 3 (representing respectively a pure power line communication gateway 100 having only a power line communication module, a pure wireless communication gateway 200 having only a wireless communication module, and a power line communication + wireless communication dual-network fusion gateway 300. The specific structure of the gateway device and the modules included are different, but do not affect the implementation of the technical solution of the present invention). The gateway includes a main control module, a short-range wireless communication module, several power line communication modules (the accompanying drawing takes three modules as an example, and it can actually support several modules), a wireless communication module, a touch display screen, buttons, and a buzzer, wherein the main control module is connected to the remaining modules.

[0062] based on Figure 1 , 2 , 3, can be used to derive a variety of heterogeneous gateway devices, and some modules originally connected to the main control module (such as short-range wireless communication module, buttons, buzzers, etc.) can be connected to the power line communication module or the wireless communication module. The power line communication module or the wireless communication module can directly process the data, or can provide a data transfer function to send the data to the main control module for processing.

[0063] The main control module is a core module that integrates control, management, computing and communication functions. In the system, it communicates with sub-devices through protocol conversion via power line communication module or wireless communication module, and has the functions of configuring and managing network information and application addresses, configuring and controlling scenes, configuring and controlling control program logic, and monitoring system equipment status; it has the ability to synchronously transmit system instructions to the cloud via the network.

[0064] The short-range wireless communication modules can exchange data when they are close to each other (the short-range wireless communication module of the gateway and the short-range wireless communication module of the sub-device can exchange data). The gateway is the main device, and the module needs to be powered, using electrical energy to provide a radio frequency field and send data to the sub-device (also called the target device, the gateway is also usually called the main device, and the module usually refers to the short-range wireless communication module of the gateway).

[0065] The power line communication module (including power line communication module 1, power line communication module 2 and power line communication module 3) is the main node role in the power line communication network, responsible for completing functions such as networking control, network maintenance and management.

[0066] The wireless communication module is the main node in the wireless communication network and is responsible for completing functions such as networking control, network maintenance and management.

[0067] The touch screen is used to select which network the sub-device wants to join in the case of multiple networks. The screen can also show the result of the sub-device touch, prompting the operator whether it is successful. If no network is selected, it will join the first matching network by default.

[0068] The button is used to select which network the sub-device wants to join in the case of multiple networks. Its function can be replaced by a touch screen. If no network is selected, it will join the first matching network by default.

[0069] The buzzer is used to make a sound when the operation is completed to prompt the operator whether it is successful.

[0070] The program modules of the power line communication sub-device 101 (also referred to as a sub-device or smart device) are as follows: Figure 4 As shown, it includes a power line communication module and a short-range wireless communication module.

[0071] The power line communication module is a slave node in the communication network. It is responsible for the management and control of sub-devices, connecting to the short-range wireless communication module based on power line communication, and is responsible for reading and writing data. In the unnetworked state, it can read valid data in the short-range wireless communication module and initiate a networking request. After the networking is successful, the data can be written to the storage medium. It can read the data in the storage medium and join the recorded network.

[0072] When the short-range wireless communication module is not powered on, it can approach the gateway device and receive data written by the gateway device. When powered on, it can provide a data reading and writing interface for the wireless communication module and provide the data required for networking.

[0073] The program modules of the wireless communication sub-device 102 (also referred to as a sub-device or smart device) are as follows: Figure 5As shown, it includes a wireless communication module and a short-range wireless communication module.

[0074] The wireless communication module is responsible for the management and control of sub-devices, the communication of wireless networks, connecting to the short-range wireless communication module and reading and writing data. In the non-networked state, the valid data in the short-range wireless communication module can be read and a networking request can be initiated. After the networking is successful, the data can be written to the storage medium. The data in the storage medium can be read and the recorded network can be added.

[0075] When the short-range wireless communication module is not powered on, it can approach the gateway device and receive data written by the gateway device. When powered on, it can provide a data reading and writing interface for the wireless communication module and provide the data required for networking.

[0076] When the above technical solution is actually applied, if it involves sub-devices, it usually refers to intelligent devices connected to the network, including but not limited to lamps, air conditioners, cameras, alarm devices, etc. The gateway device and sub-device usually have communication modules, and the types of communication modules can be power line communication modules (it can also represent wired communication modules) or wireless communication modules or short-range wireless communication modules (wireless communication modules generally have a communication distance of tens of meters at the shortest; short-range wireless communication modules are specific, and the communication range is only a few centimeters. There are two types of communication modules in sub-devices).

[0077] The beneficial effects of the present invention are as follows: the main technical problem solved is to propose a new networking method, which transmits the necessary data required for device networking through a wireless short-range communication module. The networking information can be transmitted between the gateway device and the sub-device without opening the network or closing the network whitelist, and the network can be quickly established to complete the networking. It effectively solves the security risks caused by the need to open the network in the traditional networking process, and effectively solves the interference problems that may be encountered in the networking process; simplifies the process of large-scale data transmission and permission verification in the traditional networking process, improves networking efficiency, and reduces networking time. The present invention is compatible with power line communication and wireless communication, has a very wide range of application scenarios, and meets the needs of different home improvement projects. The present invention is compatible with single-channel power line communication systems, and is also compatible with multi-channel power line communication systems, which can meet the implementation needs of projects of different scales.

[0078] The main technical problem solved by the present invention is to propose a new networking method that can support the networking of power line communication and wireless communication, improve the security of networking, improve the networking efficiency, reduce the networking time, and solve the interference problem in the networking process. The present invention also provides an implementation method of the networking method and related systems, devices and storage media.
