In the cornfields of the black soil region in the Northern Hemisphere, industrial routers are quietly reshaping traditional farming logic. On Tom's thousand-mu farmland, four industrial routers mounted in the field-side machine rooms connect soil moisture sensors, meteorological monitoring stations, and irrigation systems. When the sensors detect that the soil moisture falls below a threshold, the system automatically triggers the drip irrigation equipment and synchronizes the data to a cloud management platform. This "preventive planting" model represents a typical application scenario of industrial routers in agricultural IoT.
The essence of agricultural IoT is to achieve a closed loop of environmental perception, decision-making optimization, and execution feedback through the collaboration of sensors, controllers, and network devices. As the "nerve center" of this system, industrial routers must fulfill three core tasks:
Agricultural field devices use a variety of protocols, such as Modbus (irrigation controllers), MQTT (meteorological stations), and TCP/IP (video surveillance). The USR-G809s industrial router supports RS232/RS485 serial port and Ethernet dual-channel transparent transmission, enabling seamless connectivity with PLCs, sensors, and other devices while avoiding delays and data loss caused by protocol conversion. For example, at a vegetable base in Shouguang, Shandong, it connects to soil moisture meters via serial ports, collecting real-time data on EC values and pH levels, and uploading it to the cloud via 4G with an error rate below 0.5%.
Farmland environments are complex, with temperature ranges from -30°C to 70°C and exposure to lightning strikes and static interference. The USR-G809s adopts industrial-grade design, featuring EFT (Electrical Fast Transient) protection, ESD (Electrostatic Discharge) protection, and hardware watchdog circuits, ensuring stable operation in sandstorm environments in Xinjiang's cotton fields. Its dual-Ethernet port redundancy design supports wired/4G dual-link backup, automatically switching to 4G when the wired network fails to ensure continuous data transmission.
Agricultural scenarios require real-time responses, such as immediately shutting down irrigation systems during sudden rainfall. The USR-G809s incorporates an edge computing module capable of local data processing, uploading only effective alarm information. For example, in Jiangsu's state-owned farms, it analyzes the operation trajectories of agricultural machinery from Beidou positioning terminals, automatically identifying missed sowing areas and generating reseeding instructions, boosting machinery efficiency by 28%.
Agricultural IoT projects require selecting appropriate industrial routers based on scenario characteristics. Below is the selection logic for typical scenarios:
For small and medium-sized farms with limited budgets but a need for water-saving irrigation, routers supporting 4G full-band compatibility and dual-Ethernet port redundancy, such as the USR-G806W, are recommended. Its affordable price and built-in eSIM card slot support plug-and-play with operator SIM cards. After adopting this solution, a cooperative reported a 35% increase in water and fertilizer utilization and a 40% decrease in equipment failure rates.
For large, cross-regional farms facing challenges of device dispersion and inadequate network coverage, the USR-G809s's 5-kilometer LoRa communication capability can cover a single device radius of 5 kilometers without signal attenuation through soil. A cotton field in Xinjiang deployed this router, extending the battery life of soil moisture sensors from 3 months to 5 years while supporting over 200 devices online simultaneously.
In greenhouse environments requiring high-temperature and high-humidity resistance, the USR-G809s operates within a temperature range of -20°C to 70°C and a storage temperature range of -40°C to 125°C, adapting to extreme conditions. It supports VLAN subnet division, isolating greenhouse environmental control systems (temperature, humidity, CO₂ concentration) from security systems (cameras, access control) to prevent broadcast storms. After adoption, a base in Shouguang, Shandong, reported a 42% decrease in pest and disease incidence.
For agricultural machinery operations requiring trajectory tracking and task scheduling, the USR-G809s supports Beidou/GPS dual-mode positioning, uploading real-time machinery locations to the cloud. Jiangsu's state-owned farms used this feature combined with AI algorithms to automatically plan optimal operation paths, reducing fuel costs by 19%.
As a benchmark product in agricultural scenarios, the USR-G809s integrates 4G LTE, Wi-Fi, DIDO (Digital Input/Output), serial ports, and Ethernet ports, with the following core advantages:
