Container Terminal Wireless Communication Transmission System The Key Technical Analysis And Applications

With the economic commerce freedom going, capacity of international trade is rising, and the transport of international container is developing quickly, and become the main transports of manner of international trade. Around the world the main ports pay more attention to the efficiency of cargo loading and unloading. During the operating and dealing of container terminals, the require of the real time control to equipments, personnel, containers, and program's key are more and more highly, especially in the big busy special container terminals. Recur to developing of computer and radio-technology, It is more and more important that the application of the Wireless communications in the container terminals, the managers of container terminals are attract to down the cost, effort improve manage and efficiency, enhance terminals core competition, and take advantage in drastic warfare. At present, the application field of wireless communications is not mature and less. Aim at this topic, the paper discuss the key technology and detail applications of wireless communications. It has three main portion in the research of this paper. First, researching the wireless communications system that adapt to operating of container terminals characteristic, mostly researching and analyzing of spread spectrum communication, trunking system, WLAN etc key technologies. Secondly, researching the application requirement of wireless communications in container terminals, according to result of researching to key technologies in container terminals, bring forward some projects of wireless communications system which can suit the container terminals requirements, and compare those projects, explain advantage and disadvantage among the projects. Thirdly, for example Ningbo III container terminal, combine with theory and practicality, applied the theory of container terminals wireless communications system, realize the terminals operating wireless require. And base on the wireless communications network, papers introduce the content GPS, RFID etc on technologies which can develop and apply in future.
