Description
Technical field
The present invention relates to the fields such as the system integration, financial system technology, computer science and technology, are to be based on specifically
Infrared electronic technology designs and the golden guard system with power-off protection function.
Background technology
Financial system is the flowing about fund, a system of collection neutralization distribution.It is by connection surplus fund person and
The organism that a series of financial intermediaries for the person of lacking of capital and financial market collectively form.Financial system be family,
Company and government is perform a set of market and intermediary that its Financial Decision uses, including stock, bond and other security
Market, in addition to the financial intermediary such as bank and insurance company.Fund is flowed to from surplus fund side by financial system and provided
Golden shortage side.These funds are generally flowed by financial intermediary.
Financial system is family, company and government to perform a set of market and the intermediary that its Financial Decision uses,
Include the market of stock, bond and other security, in addition to the financial intermediary such as bank and insurance company.
Fund flows to the side of lacking of capital by financial system from surplus fund side.These funds generally pass through financial intermediary's machine
Structure flows.
As construction of the construction of system Construction financial system with other industry electronic system, " life is mainly used
Periodic method " is carried out." Life Cycle Method " is sometimes referred to as Minute stage construction method or step by step establishment law, and its main thought is by one
The system of individual bulky complex resolves into the stage that several easily realize or appointed with used engineering method sequentially in time
Business, one task of one stage an of stage or a task go to realize.Generally, the previous stage is the work of latter stage
Make basis, latter stage only could formally start after the completion of the previous stage is satisfactory.Therefore, this system engineering is passed through
Method, no matter how big engineering or how complicated system, can be without any confusion, Minute stage construction success step by step.
In the cycle of system Construction, it generally can be divided into project starting, feasibility study, network analysis, system design, program
Design, system testing, go into operation eight stages such as application and operation maintenance.If eight stages in life cycle are distributed in
Between on abscissa, and by workload, manpower demand, computer resource or credit requirement etc., represented with the ordinate of vertical direction,
Various curves show：Manpower, computer resource needed for each phased mission of system Construction etc. can quantitative estimate
Meter.So each stage can be carried out in controllable scope, so as to ensure that the efficient of any big system Construction task
Complete.
MIS in the bank itself, caused by its business characteristic, can be divided into counter service processing subsystem,
Inter-bank settlement service process subsystem, internal control subsystem and new services subsystem, each subsystem can also equally enter
One step is divided into several subsystems.As again counter service processing subsystem can be again divided into depositing, provide a loan, save, converge
The multiple business processing system such as convert.And for the construction of every kind of electronic transaction processing system, Life Cycle Method can be used
It is managed, it is the scientific method for guaranteeing both quality and quantity to complete e-finance system Construction.
The so-called system integration（SI, System Integration）, it is exactly the comprehensive wiring system and meter by structuring
Calculation machine network technology, equipment (such as PC), function and the information of each separation are integrated into be mutually related, it is unified and
Among the system of coordination, resource is set to reach fully shared, realization is concentrated, be efficient, convenient management.The system integration should use function
A variety of integrated technologies such as integrated, the liquid crystal-spliced integrated, comprehensive wirings of BSV, system integrating, software interface be integrated.The system integration is real
Existing key is interconnection and interoperability issue between solution system, and it is multi-vendor, multi-protocols and towards various
The architecture of application.This needs solve various kinds of equipment, the interface between subsystem, agreement, system platform, application software etc. and son
System, architectural environment, construction coordinate, all related to staffing of organization and administration towards it is integrated the problem of.
In financial system is integrated, in Financial Management service system（Golden guard system）In, some facilities and equipments need to realize
