Ⅰ. Project Overview
In networking scenarios involving heavy mobile equipment like port cranes, traditional wired transmission methods face fundamental challenges. The physically separated and continuously moving nature of the equipment makes cable installation extremely difficult, costly, and prone to damage. To address this core issue, we propose a coverage network solution based on wireless base stations, using wireless connectivity to overcome physical limitations.
Ⅱ. Solution: High-Reliability Wireless Base Station Network
This solution employs Comark industrial wireless base stations to build a dedicated network, completely eliminating wiring hassles. It supports long-distance point-to-point and point-to-multipoint transmission, suitable for vast areas like ports and factories, delivering lasting and stable high-quality wireless service through a one-time deployment.
Core Design Features:
Dedicated Frequency Band, Strong Anti-Interference: The complex electromagnetic environment at ports often interferes with common 5.2/5.8GHz bands. This solution utilizes 6GHz spread spectrum technology, effectively avoiding public band congestion, significantly reducing latency and packet loss, and ensuring stable transmission for control data and video streams.
Ring Network Redundancy, Uninterrupted Links: Wireless base stations are configured in a dual-homed ring structure, leveraging the CK-Ring self healing ring network technology of Comark industrial Ethernet switches. If any node or link in the network fails, the system can automatically and seamlessly switch between primary and backup links within 20 milliseconds, guaranteeing "zero-interruption" data transmission.
️Industrial-Grade Design for Harsh Environments: All equipment meets industrial reliability standards, specifically designed to withstand harsh port conditions such as high humidity, salt spray, temperature variations, and vibration.
Ⅲ. Equipment Technical advantages
