Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wireless communication, and particularly relates to a low-power long-distance wireless communication method, system and device based on Matter. BACKGROUND

[0002] The key technology of the Internet of Things is connection and transmission. With the development of the Internet of Things technology, a large number of communication technologies have emerged. These communication technologies promote the application of the Internet of Things technology in various industries, but at the same time, they also bring about the diversity of device communication methods and the complexity of communication technologies, increasing the difficulty of interconnection between devices. How to integrate multiple communication technologies to realize the interconnection between devices has become a technical problem to be solved in the field of the Internet of Things.

[0003] On the one hand, LoRa (Long Range Radio) technology is becoming mature, and domestic LoRa chips are also rapidly emerging. LoRa has been widely used in wide area network communication due to its low power consumption and long transmission distance. On the other hand, the Connectivity Standards Alliance (CSA) released the Matter 1.0 standard in October 2022. After a year of development, the CSA released Matter 1.1 in May 2023. Matter, as an open-source standard, aims to connect devices from different ecosystems together. Any smart device can use it to create a more seamless smart experience. The emergence of the Matter standard is beneficial to breaking down the barriers between different smart devices, thereby realizing the interconnection between devices. However, it is mainly designed for local area networks. How to solve the problem of interconnection between Matter devices and wide area network devices, and realize long-distance communication, is still lacking an ideal method.

[0004] There are mainly the following solutions: First, register Matter devices on the cloud, use the API, protocol or cloud service provided by the cloud platform to realize communication between Matter devices and wide area network devices. However, this method may cause problems in data transmission delay and availability. In addition, using a cloud platform may involve data privacy and security issues, and the security and compliance of the cloud platform need to be ensured. Second, use network address translation (NAT) penetration technology to expose Matter devices to the public network, so that they can directly communicate with wide area network devices. By configuring network devices and firewall rules, data can be transmitted between public and private networks. However, NAT penetration may involve network settings and firewall rule adjustments, which require certain technical knowledge and operational capabilities. In addition, opening the public network access of the device may increase the security risk. Therefore, a method is needed to solve the use demand of Matter device remote or cross-network communication. SUMMARY

[0039] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These embodiments are based on the technical solution of the present invention and provide detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0040] Example 1

[0041] The embodiment provides a low-power long-distance wireless communication method based on Matter, comprising the following steps:

[0042] Gateway configuration is performed, and the gateway supports Matter and LoRa;

[0043] Matter terminal equipment is connected to a Matter network;

[0044] LoRa terminal equipment is connected to a LoRa network;

[0045] The LoRa network and the Matter network are connected through the gateway, so that data of the LoRa terminal equipment and data of the Matter terminal equipment are interchanged.

[0046] The LoRa network comprises a LoRaWAN and a LoRa ad hoc network, and data of a LoRaWAN device and data of a LoRa ad hoc network device are received, respectively. The embodiment can realize autonomous analysis of LoRaWAN data and LoRa ad hoc network data, and can automatically identify whether the data is LoRaWAN data or ad hoc network data when receiving LoRa data. Compared with the official networking method LoRaWAN, the LoRa ad hoc network is more flexible and does not need to depend on a base station. When designing the LoRa ad hoc network, the official LoRaWAN is compatible, so that the traditional LoRaWAN node and the ad hoc network node can be directly connected to the system.

[0047] Preferably, when the Matter terminal equipment is connected to the Matter network, authentication is performed through DCL; and when the LoRa terminal equipment is connected to the LoRa network, encryption is performed through an AES algorithm or a DES algorithm. Through the fusion of the security mechanisms of the two, the security of device connection and transmission can be greatly improved.

[0048] Specifically, the connection of the LoRa network and the Matter network comprises the following steps, as shown in Figure 3

[0049] S101, installing a gateway supporting Matter and LoRa designed by the embodiment, and initializing a network;

[0050] S102, configuring Matter terminal equipment to access a Matter network;

[0051] S103, configuring LoRa terminal equipment to access a LoRa network;

[0052] ​S104, judging whether the LoRa terminal device is a LoRaWAN device, if yes, acquiring the LoRaWAN device through BLE or LoRa, updating the LoRaWAN device list; if no, it is a LoRa ad hoc network device, waiting for the LoRa ad hoc network device to be powered on, periodically sending a network access request, and after the gateway receives the network access request, assigning a unique ID to the LoRa ad hoc network device for subsequent device management;

[0053] S105, after the gateway acquires the LoRaWAN device list or the LoRa ad hoc network device network access request, the connection between the LoRa network and the Matter network is established through multiple data interactions (parameter transmission), realizing the access of the LoRa terminal device to the Matter network.

[0054] Through the established network connection, the data interaction between the LoRa terminal device and the Matter terminal device can be realized. After the gateway receives the data of the Matter terminal device, the message is preprocessed, converted into data recognizable by LoRa, and then sent to the LoRa terminal device. In this way, the LoRa terminal device can be controlled on the Matter terminal device side, and the coverage of Matter is further expanded through the characteristics of low power consumption and long communication distance of LoRa. In particular in the scenarios of smart park and smart street lamp, the application range of Matter network is wider, more smart devices can be connected to the Matter network, making the application scenarios of Matter more flexible, and enhancing the interoperability between smart devices in different networks.

[0055] In addition, in the Matter standard protocol, the system can only perform network configuration through BLE. Through data processing and protocol conversion, the information required by the Matter network, such as secret keys, can be sent to the terminal by LoRa, so that the device can be accessed remotely.

[0056] In a preferred embodiment, the present application can realize the relay function through LoRa in the gateway. The gateway can transmit the data in the Matter network received by the gateway through LoRa in the gateway. After the relay gateway receives the data, it decides the direction of the next transmission according to the protocol field, so as to realize multiple relays, thereby greatly expanding the coverage of Matter, so that Matter technology can be applied in street lamp network, village lamp network and other scenarios.

[0057] The specific process is as shown in Figure 4 The specific process is as shown in

[0058] S201, judging whether it is data sent by a standard Matter terminal device, if yes, entering step S202, if no, it is data sent by a LoRa terminal device, entering step S204;

[0059] S202, data analysis is performed to determine whether the target device of data transmission is a Matter terminal device, if yes, transmission to the monitoring center; if not, the target device of transmission is a LoRa terminal device, step S203 is entered;

[0060] S203, it is determined whether the received data needs relay transmission, if yes, the data frame is added to the relay information and relay transmission is performed through LoRa; if not, the data frame is converted and the data is sent to the target device to realize data interaction;

[0061] S204, it is determined whether the data type belongs to standard LoRaWAN device data or LoRa ad hoc network device data, and pre-data processing is performed respectively, step S203 is entered.
