Industrial Ethernet switches have a wide range of application cases across multiple industrial sectors, including automotive manufacturing, oil exploration, agricultural mechanization, urban utility tunnel inspections, offshore wind farm operations and maintenance, cold-chain logistics, intelligent transportation, power energy, security surveillance, and smart factory production environments.

In the automotive manufacturing sector, it is widely used in smart factories and automated production lines. For instance, in a smart factory project at a certain automobile manufacturer, switches enhance network reliability by providing high-bandwidth, low-latency data transmission along with redundancy features—effectively minimizing production disruptions caused by network failures. At the same time, these switches connect hundreds of robots and controllers, enabling efficient production scheduling and real-time monitoring.

In the oil exploration sector, an Arctic-region oilfield project has deployed the HY5700-8GP-M12 ruggedized vehicle-mounted industrial Ethernet switch. Thanks to its -40°C cold-start capability and IP67-rated dustproof and waterproof design, the device continues to operate reliably even in extreme cold temperatures as low as -38°C and during harsh sandstorm conditions. This ensures seamless real-time transmission of downhole sensor data to the surface control center, boosting the integrity rate of exploration data from 82% to an impressive 99.6%.

In the realm of agricultural mechanization, a leading modern agriculture group has equipped 200 autonomous harvesters with identical switches. These switches connect LiDAR sensors and Beidou positioning modules via Gigabit M12 interfaces, enabling centimeter-level precision in path control. Additionally, PoE+ power supply technology reduces wiring complexity by 70%, while significantly lowering failure rates—by as much as 90%—compared to conventional equipment, even in high-humidity environments. As a result, rice harvesting efficiency has improved by 35%.

In the field of urban utility tunnel inspections, a smart city project in Shanghai has integrated switches into inspection robots, leveraging their 20-kilometer single-mode single-fiber transmission capability to relay 4K infrared thermal imaging footage captured 30 meters underground. This setup ensures secure communication even in hazardous environments with methane concentrations as high as 1.5%, while ERPS ring network self-healing technology (with a 20ms switchover) prevents data loss during fiber cable disruptions—boosting fault response speed by up to four times.

In the offshore wind power operations and maintenance sector, an offshore wind energy group has equipped its service vessels with this switch. Featuring 4kV surge protection and salt-spray corrosion resistance, the device ensures stable transmission of turbine vibration sensor data even in sea conditions up to Force 8. With a packet forwarding rate of 23.8 Mpps, it can simultaneously handle 20 streams of 4K video along with SCADA system data, reducing a single offshore maintenance mission cycle from 72 hours to just 48 hours.

In the cold-chain logistics sector, switches are used in multinational cold-chain transportation networks within mobile relay communication vehicles. These switches seamlessly operate between -25°C freezer compartments and outdoor environments at 35°C, thanks to advanced dynamic temperature-control compensation technology. With a 1Gbps bandwidth, they efficiently support real-time aggregation of temperature and humidity data from over 1,000 cold-chain containers. Additionally, an anti-mold coating ensures the equipment operates flawlessly for up to three years.

In the smart transportation sector, within urban metro projects, the HY5700-754GX24GT switch utilizes a 10-gigabit backbone connection paired with gigabit access to meet the demands of high-definition video backhaul. Additionally, ERPS ring network technology ensures zero packet loss during seamless switching. In highway scenarios, the switch handles tasks such as uploading data from front-end cameras and transmitting traffic light control signals, thereby enhancing overall traffic management efficiency.

In the power energy sector, the Taklamakan Desert photovoltaic base has deployed this switch, supporting cold starts down to -40°C and featuring a dual-power redundancy design to ensure real-time data transmission from inverters. Additionally, its traffic-shaping capability helps reduce the solar curtailment rate by 0.8%, resulting in an annual power generation gain exceeding 5 GWh. Meanwhile, in the Baihetan-Jiangsu ±800kV ultra-high-voltage project, the switch has established a robust triple-layered protection system, maintaining an error rate below 10⁻¹² even in radiation environments as low as 10 V/m. In the event of fiber-optic cable failure, the system switches over within 20 milliseconds, preventing potential losses exceeding 20 million yuan.

In the security surveillance field, a city's large-scale surveillance network relies on switches equipped with 4 Gigabit optical ports and 24 Gigabit copper ports to support the seamless integration of multiple cameras. Advanced features like intelligent traffic management and QoS capabilities ensure smooth video transmission, while DoS protection and dynamic ARP detection help safeguard against network threats, ultimately ensuring the secure delivery of surveillance data.

In the smart factory manufacturing sector, AOI inspection equipment used in electronics manufacturing plants leverages the PTP precision clock protocol and WRED algorithm via a switch to reduce image transmission latency from tens of milliseconds down to microseconds, significantly enhancing detection speed and accuracy while cutting defect rates by approximately 30%. Meanwhile, the AGV scheduling system in automotive manufacturing employs VxLAN tunneling technology to minimize communication delays, boosting on-time delivery performance from 80% to over 95%. Additionally, robotic production lines are fortified against potential attacks through an ARP intrusion detection engine and IP/MAC binding features, ensuring precise command transmission. Finally, multi-technology systems—including PLCs, SCADA, and vision systems—are isolated using QinQ double-layer VLAN tagging, reducing data transmission latency by about 50% and extending equipment MTBF by roughly 30%.
