In order to solve the problem in transmitting video signals and control signals between the gantry crane and control center of Xiamen Haitong Port, Jaguar Wave construct the wireless private network based on mmWave technology, realize real-time wireless transmission of signals.
Challenge
Waveguides were used for data transmission in Haitong Port, but the data transmission was extremely inconvenient due to different waveguides of each manufacturer cannot be interconnected, so a wireless transmission way is needed for video signals and control signals real-time transmission, which the wireless transmission delay would be controlled within 30ms.
Solution
Two or three mmWave devices are installed on each gantry crane, which are connected to the gantry crane and the central computer room respectively, so that the crane can maintain smooth network communication with the central computer room under the working state of movement. The mmWave network provides signal coverage for the container yard, ensuring stable signal transmission with low latency and high rate.
Results
The demand of Hitong Port for real-time wireless transmission of monitoring data and gantry crane instructions can be met via mmWave private network, the transmission rate can reach 1.8Gbps and the delay is less than 30ms.
mmWave wireless networking mode solves the problem of complex and inconvenient wiring in the port environment, and the security issues caused by wiring can be eliminated.
The transition rates of the gantry crane has greatly improved benefit from the high speed, low latency and high stability mmWave network, making it more efficient..
The unique mmWave frequency band is not interfered by other wireless bands, forming network isolation and ensuring transmission security.
Smart Port is a necessary trend for the development of port in the next years, reducing costs and increasing efficiency through remote control, automatic control, automatic driving, intelligent monitoring and other technologies has become the common demands of ports around the world. The wireless private network built by mmWave devices can fully meet various demands of remote control scenes of gantry crane due to its high speed, low latency and high stability, it is expected to completely replace fixed networks in the future, improving efficiency while greatly reducing labor costs.
