As the country progresses, a magnificent feat is unfolding in the remote mountainous regions-the vigorous construction of expressway. Once, towering mountain ranges served as an insurmountable barrier to development and communication, but now, a series of expressways, like winding dragons, traverse the steep and lofty terrain, seamlessly connecting isolated mountain villages with the outside world, infusing fresh vitality and boundless hope into these mountainous areas.
Project Background
Inside expressway tunnels, there exists an intricate network of control systems typically utilized for vehicle inspection at tunnel entrances, variable message sign, interior lighting, and more. To achieve efficient interconnection and data communication among these devices, numerous conversion devices are often required. Conventional Industrial Ethernet Switches are limited to optical fiber and RJ45 Ethernet cable connections, unable to interface with the RS485/RS32/RS422 ports of PLC control systems. Therefore, we have introduced Serial Port Industrial Ethernet Switches, which perfectly address this issue, paving the way for intelligent tunnel management. Additionally, we offer comprehensive solutions aimed at further enhancing tunnel operational safety and efficiency.
