Applications of AM5728-based 5G Smart Gateways in the Industrial Internet
Xinmai's AM5728 Development Platform-based 5G Smart Gateway
With the rapid development of the Internet and the Internet of Things (IoT), coupled with the national policy requirements of "Made in China 2025," various industries need to implement information-based management for production to improve production management efficiency and energy efficiency, thereby promoting the development of national Industry 4.0. Therefore, the informatization and monitoring of the five key production elements (Man, Machine, Material, Method, Environment) have become a major urgent need. The essence of the IoT is the interconnection of all things, requiring the sensing and control of object dynamics, which necessitates various sensors and controllable devices, such as temperature and humidity sensors, wind speed sensors, infrared sensors, single-lamp controllers, etc. However, in industrial sites, various devices use different protocols, installation methods, and communication methods, making it difficult to collect and transmit data according to unified standards. The purpose of smart industrial gateways is to unify different protocols and provide multiple communication methods to transmit data to cloud servers as data support for platforms. In the era of ubiquitous connectivity, smart gateways act as bridges between various devices, building communication channels.
As data collection and monitoring of numerous production elements require management via data gateways, industrial data gateways are indispensable processing units. Currently, the mainstream solution involves using ARM/DSP as the processing platform for industrial data gateways.

Rich industrial automation communication protocols are built-in (Modbus RTU/Modbus TCP, Siemens series, Omron series, Mitsubishi series, AB series, Power 101, 104, DLT645 meter protocol, private protocols, etc.), adaptable to various field devices. Devices connect to cloud platforms for remote management, featuring a PC Client and a high-performance hardware solution. It can access third-party cloud platforms, such as Microsoft Azure IoT, Gizwits, Alibaba Cloud (LinkWan Platform, Edge Computing Platform, Smart Gateway Platform), Baidu TianGong, and other cloud platforms. The convenient and easy-to-use PC Client software enables remote configuration, data monitoring, and establishment of maintenance channels for smart devices like PLCs. Data transmission offers high security and reliability, providing secure and reliable access, supporting encryption methods such as DES and 3DES, with optional VRRP hot backup functionality. The cloud employs distributed server deployment, capable of connecting a large number of gateways and terminal devices.

In an Industrial IoT (IIoT) platform, the smart gateway serves as the data acquisition layer for edge computing, where data collection and protocol parsing at the link layer are crucial. The platform is the core of the Industrial Internet, and data acquisition is the foundation of this core. Within the entire process of data acquisition, data transmission, data analysis, and data application, the smart industrial gateway is positioned as the bridge for data collection and transmission. Industrial smart gateways feature common industrial ports such as RS485, RS232, CAN, analog inputs, and Ethernet ports, enabling functions like data acquisition, data forwarding, data distribution, edge computing, and protocol conversion, providing a reliable data foundation for the Industrial IoT.
