Research Of Coaxial Measurement And Calibration Technology Based On LD/PSD

As the logistics technology developed, Corporation pay more attention to the efficiency in logistics with enlarging the industry of storage and transportation. So the container harbor logistics system being a important node in logistics chain attached more importance to people than ever. Container harbor system, As it is flexible integrity that including container, ship, load and unload convey mechanism, berth field, road, worker and communication touch all array at container harbor. Container harbor, as a container transportation system hinge pay a extreme role in enhancing national and international trade, and increase efficiency in container transportation system, further more, field as a important dot in container harbor system, under the control in artificial and con- robotization management state field database revision reliability couldn't be promised. The logistics efficiency was still low, so how to enhance field attemper efficiency is a task to solved urgently. So this thesis stands the point of how to enhance field efficiency, bring forward a viewpoint, namely a set of field management information system, that to achieve automation, intelligence, information management.According to the requirement , the paper summarizes development and status quo of container harbor, digital field , management information system , field bus in home and world,Management information system of warehouse is the emphases of the research. Combined with the requirement of SPCWT, to reach requirement and performance analysis of the system, a set of digital intelligentized field animation system to be established is cardinal element, all rely on container field technology, based on VC++. The system realizes information integrated and dynamic animation on goods imported and exported data management, with guide to the dialog mainframe and explanatory words. During design , goods imported and exported , queried data management come true with a management system database model and proper accessing technology, viaconcept design, logical structure design and physical structure design.The writer achieves management information system and researches the field bus to the certain extent, further more, brings forth the design method to the Profibus-DP Intelligent Slave Device .Dialog mainframe makes bridge for user and internet applications, and represents humanity. The thesis introduces primary dialog mainframes and operation process.The thesis summari/es the whole work and brings forth suggestion and view.
