Design And Implementation Of The All-in-one Card System In D Industrial Park

D industrial park one-card system is an advanced digital information system with database as the core and IC card as the medium.The system includes the organization of network communication architecture,the selection of control equipment and the development of management software.This system in the local area network(LAN),the data through the B/S and C/S network structure model of communication,the whole system has a central database and local database,business data flow only in the hairpin and cancellation of bidirectional flow between the central database and local database,other conditions only flow between local library with the local library.Controlling the data flow only occurs between the local library and the device.The system selects Delphi\Visual c++ as the development tool,which can conveniently and concisely operate the objects in the database and satisfy the reading of related data.Based on the research and development of smart CARDS at home and abroad and the great promotion of one-card in the market,this paper decides to build an intelligent and information-based one-card system based on the situation of logistics support service before the system design of d-industrial park.The system design,through the analysis of the needs of the characteristic users of the park and the requirements of the system construction,builds the network topology of the one-card system on the whole,and divides the system into six modules of card center,access control,attendance,consumption,online patrol and parking lot management as required.Select TCP/IP protocol communication,adopt network mode based on B/S three-layer architecture,complete the requirements of server database and workstation application design,and plan the system design model in general.After that,all kinds of functions that the software of each module will realize are described in detail.After the registration of the card center,relevant licenses are automatically generated in the database of other modules,so as to achieve the corresponding functional operations of access control,attendance,consumption and other aspects and achieve the system data sharing,providing convenience for users.Finally,based on the design of software functions,the layout of hardware equipment is reasonably set up,and the system construction is realized under the guidance of theory.In fact,the construction of six modules of one card is completed.
