Description

Technical Field

[0001] This utility model relates to the field of Internet of Things (IoT) technology, specifically a gateway based on Sub-1GHz transmission plus Ethernet communication. Background Technology

[0002] In data transmission scenarios such as the Internet of Things and industrial control, gateways serve as key hubs between devices and terminal data processing nodes, undertaking the core functions of data forwarding and interaction. Currently, existing gateways generally use WIFI or 4G / 5G wireless communication technologies to transmit data to the home gateway, thereby completing subsequent data processing.

[0003] However, traditional gateways using Wi-Fi communication are limited by their limited signal coverage, making it difficult to support reliable data transmission in long-distance, large-scale deployment scenarios. Secondly, while gateways based on 4G / 5G mobile communication have wider coverage, the associated data charges are higher, resulting in significant long-term operating cost pressures. Furthermore, in indoor or complex industrial environments, obstacles such as walls and equipment can easily cause signal attenuation, reducing communication stability and effective transmission distance. In addition, gateways using Wi-Fi or 4G / 5G communication modules have relatively high hardware costs, which is not conducive to large-scale deployment and widespread application. More importantly, in remote areas, underground spaces, or special scenarios where mobile networks are not available, such gateways cannot establish effective communication links, greatly limiting their application scope and practicality.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0015] Example 1: Please see Figure 1 As shown, this utility model provides a gateway based on Sub-1GHz transmission plus Ethernet communication, including a CPU and a physical layer chip. The CPU and the physical layer chip are bidirectionally electrically connected, and the physical layer chip is bidirectionally electrically connected to the Ethernet wired communication interface. The output of the CPU is electrically connected to an SPI FLASH, a Sub-1GHz communication module and an LED module, respectively, and the input of the CPU is electrically connected to a low dropout linear regulator.

[0016] This technical solution effectively overcomes the limitations of traditional gateways using WIFI or 4G / 5G communication technologies by combining Sub-1GHz wireless communication with Ethernet wired communication. The Sub-1GHz communication module operates in the 300MHz-920MHz frequency band and has advantages such as wide signal coverage, strong penetration, long transmission distance, and low power consumption, making it suitable for reliable data transmission in remote areas, underground spaces, and complex industrial environments.

The DW port is used for specific peripheral interfaces or debugging functions, providing additional input / output or communication expansion capabilities to the system. The hardware watchdog monitors the CPU's operating status, triggering a reset signal to force a system restart to restore normal operation when the CPU crashes or the program malfunctions. The Reset / Reload switch allows for manual restarting of the system program during system fault debugging or program updates. The SPI FLASH stores system programs, configuration parameters, running logs, and other data, ensuring data integrity even when power is lost.
