Stable Connections in Extreme Environments: Comparative Evaluation of Industrial Routers' Weather Resistance Performance
In today's rapidly developing Industrial Internet of Things (IIoT) field, the stability and reliability of network connections are crucial. Especially in extreme environments, such as industrial sites with high temperatures, low temperatures, high humidity, dust, or intense vibrations, ordinary routers often fall short. Therefore, industrial routers specifically designed for industrial environments have emerged. This article will explore the weather resistance performance of several mainstream industrial routers on the market through comparative evaluations.
IIoT integrates various sensors or controllers with sensing and monitoring capabilities, as well as technologies such as mobile communications and intelligent analysis, into industrial production processes to improve manufacturing efficiency, enhance product quality, and reduce costs and resource consumption. As one of the cores of IIoT, the network is responsible for transmitting data between different levels of the system. Industrial routers, as key devices for network connections, have their stability and reliability directly related to the operational efficiency of the entire IIoT system.
Compared to ordinary office environments, industrial environments have more unpredictability and complexity. For example, in hot summers or high-temperature work areas, equipment may face temperatures exceeding 50°C; in cold regions or frozen environments, temperatures may drop below -30°C. Additionally, high humidity, dust, and vibrations generated by mechanical equipment can all pose threats to the normal operation of network equipment.
Industrial routers utilize electronic components with a wide temperature range to ensure normal operation in extreme temperatures. At the same time, they employ heat dissipation designs, such as using heatsinks, fans, or thermal conductive materials, to effectively manage internal heat. For instance, PUSR's 4G industrial router USR-G806w and 5G cellular router USR-G816 both adopt metal casings and are equipped with heatsinks, capable of maintaining stable operation in high-temperature environments.
The protection rating of the device casing is crucial for resisting dust and moisture. A high protection rating can prevent dust and water from invading, protecting the internal circuits from external environmental damage. The PUSR's 4G industrial router USR-G806w and 5G cellular router have achieved high protection ratings, effectively resisting dust and moisture intrusion. In contrast, USR-G805 adopts PP plastic material, which, although innovative in design, may be slightly inferior in terms of protection rating.
In industrial environments with intense vibrations, shock-resistant design is essential to ensure device stability. The internal components of industrial routers are reinforced to reduce the impact of vibrations. When necessary, shock-absorbing brackets or fixing devices are used to reduce vibration transmission. Puhuangtu R300A and Yinghantong IR302-LQ20-W excel in shock-resistant design, ensuring stable operation in vibratory environments.
Good electromagnetic compatibility (EMC) is key for industrial routers to resist electromagnetic interference and maintain stable signal transmission. In industrial sites with complex electromagnetic environments, routers with strong anti-interference capabilities can ensure stable data transmission. USR-G805 adopts advanced EMC design, capable of maintaining stable network connections in electromagnetic interference environments.
Stable power design is the foundation for ensuring the continuous operation of industrial routers in extreme environments. Designs such as power redundancy, overvoltage protection, and overcurrent protection ensure that power fluctuations do not affect device operation.
Industrial routers supporting multi-link backup and link aggregation technologies can automatically switch to a standby link when one network link fails, ensuring network continuity. Meanwhile, remote management functions allow operators to remotely monitor and configure devices through the network, reducing the difficulty of field maintenance. PUSR's 4G industrial router USR-G806w and 5G cellular router USR-G816 support these functions, ensuring high network availability and ease of maintenance.
Airbus has built the largest and most efficient supply chain system in the global manufacturing industry by applying sensor network technology in its supply chain system. Steel enterprises use various sensors and communication networks to realize real-time monitoring of the width, thickness, and temperature of processed products during production, improving product quality. These successful cases are all inseparable from the stable and reliable network connections provided by industrial routers.
