In modern ports, terminals and freight yards, especially container terminals, the job scheduling system is one of the most important operating systems, which can effectively improve work efficiency and service quality, and reduce the incidence of errors.
However, the geographical location and special functions of the terminal have made it inconvenient to adopt a wired transmission network. Large cranes such as bridge cranes and tire cranes need to be moved, and the transportation lanes of container trucks are not easy to lay cables. The wireless MESH network has the characteristics of high mobility, strong confidentiality, anti-interference and convenient erection and maintenance. It is the ideal choice for such scenes with such features as frequent movement of equipment and inconvenient laying of wired networks.
The reporter learned from professionals that the current wireless dispatching system is becoming more and more popular in dock applications. In the entire dock area covered by wireless signals, the dispatch center can directly send job instructions to the vehicle terminal or handheld terminal. The staff can obtain the required commands and data anytime and anywhere, and command large-scale equipment such as bridge cranes and gantry cranes and cards in real time. Reasonable operations such as forklifts have greatly improved the efficiency of operations such as loading, unloading, port collection, container dumping, transportation, etc., and provided an excellent network foundation for the construction of information ports. However, the development of wireless terminals still faces many challenges, such as multipath effects, wireless interference, coverage dead angles and network reliability.
It is reported that the terminal has serious problems of wireless co-frequency and frequency interference. Using the general cable scheme, not only can it not meet the actual needs well, but also affect its daily operation. Recently, we noticed that Shanghai Waigaoqiao Container Terminal took the lead in introducing wireless MESH technology to wirelessly cover nearly 1 million square meters of yards, providing a stable information transmission platform for real-time dispatching system of card collection and GPS location of large equipment. Serving it is a young Chinese local high-tech company - Shanghai Xinchuang Communication (GBCOM) Technology Co., Ltd. With its special technical advantages such as smart antenna technology, fast power control technology, dynamic inter-frequency networking technology, seamless soft handover technology, packet-level dynamic routing adjustment technology, and video service optimization technology, GBCOM provides a full range of routers including wireless MESH products. MESH terminal cards, long-distance APs, high-performance wireless bridges and other highly competitive wireless broadband products have been applied to the yard wireless coverage of multiple container terminals, and are highly recognized by the market. The wireless network of Waigaoqiao Container Terminal fully reflects the wide coverage, high bandwidth, excellent wireless performance, strong anti-interference ability, safety and reliability of GBCOM wireless MESH network. In addition, GBCOM will also provide high-performance MESH cards, using terminal relays to achieve a full range of dead-end coverage of Waigaoqiao container terminals.
It can be seen that the use of high-tech communication means can not only reduce the cost of information construction, but also improve the operational efficiency and benefits of the terminal. It is understood that other container terminals across the country are also actively considering the use of wireless broadband communication products, fueling the construction of terminal information.
