The Management System Of Container Business Based On Wlan

With the improvement of port operation and management, The Competition of Operation Zone and Port business is becoming more and more fierce. Just from the appearance of this competition, the point focus on Ship and cargo, but in fact, the main point is information competition. To perfect the information system in port area is an important embody of Modern Port Management. By resolving each production entity to transfer and change the information wide, accurate, currently, dynamically, rapidly and continuously. The each production entity includes in port area and out port area, market and ship, freight flow and traffic, shipping technology and shipping equipment, production command and decision analysis. By dealing with the dynamic data and the continuous track, collect, dispose, storage, analysis, feedback of numerous information, to satisfy data exchange and share of dynamic management of ship production and cargo collecting and distributing.According to the production need of Tianjin Port No.1 Stevedoring Company, on the basis of management system of container business aboard and outside, by ample demonstration, The management system of Container business analyzed the existing operation process of all users, then summarizing and abstracting the data model of whole operation system. Then according to the business and data process, by using standardizing, normalizing, technical ways to establish a management system of container business, then realize the control and manage of the operation.For connect the disperse Gantry crane, Crane and dispatching center, to realize the overall working of operation system, we take the measures of wireless communication to fill the need of port. To improve the efficiency of container operation, achieve the goals of computer managing and controlling, the wireless communication system solve the problem of data exchange of transport vehicle and umbrella loading bridge. WLAN use the criterion of IEEE 802.11b, and it use the way of 2.4GHz DSSS(Direct Sequence Spread Spectrum), the maximum transmission speed is 11Mb/s. To avoid the mutual disturbance of Wireless Base Station's signal, at the time of design the WLAN, it should put the system existing into consideration. Then to realized the seamless automatic roaming in port area, then all of the work zone have been covered by Wireless Base Station's signal, the wireless terminal on mobile machine could receive the signal anywhere anytime. Then implied RT exchange of information data of container business dispatching and large machine.During the developing process, we use the theory of information project as the guidance, use the relationship between entity to build the data model, and use the language of facing the object, finally realized the dynamic management of our company's container business on this platform, then improve the efficiency of operation production, create a huge economic benefit.
