The Design And Implementation Of ATM Service Provider System

ATM Service Provider system is a support system which provided by ATM manufacture for his ATM modules and the implement confirms to WOSA/CEN XFS standard.This system is used to support for application of bank to drive ATM modules to work for business processes(Dispense,Deposit,Read Card,Print details).People meet all kinds of trouble when designing and implementing the ATM SP.There are many modules will be equipped in ATM which individually has complex logic of business.The people who designs ATM SP should not only consider of business,but also how to monitor and control the status data of machinery modules.It is a highly complex thing to use the classic object oriented methodology to design and implement this system.We will do research on how to design and implement a ATM SP with high expandability,high performance,high maintainability.There are several aspects will be focused in this article as following:1.Functions classed by WOSA/XFS 3.10 standardBased on the WOSA/XFS standard,I complete the requirement analysis for ATM SP firstly.The requirement can be used to design ATM function set and software architecture.2.The design and implementation of ATM SP FrameworkBased on the complexity character of ATM,ATM SP Framework uses layer structure style to design ATM SP.The layer structure design style can improve the scalability of software.This section includes the design and implementation of XFS Manager layer,command scheduled layer,FSM layer and module layer.The design of ATM SP Framework can make SP system to have high maintainability.3.Define status transference diagram for RecycleBased on the FSM layer of ATM SP Framework,I complete the design of status transference diagram for ATM recycler.The status transference diagram is the base for advanced recycler SP implement with FSM.The status transference diagram reflects the status flow in the event triggers for different modules.4.Implement ATM SP according the Status Transference Diagram with FSMBased on the status transference diagram,completing the implement process of ATM SP for ATM recycler module.So,it is a significative job for the development of ATM SP with the framework designed in this article.
