Design And Implementation Of Banking Network Fault Diagnostic Systems

In recent years, the network of bank breakdown becomes more numerous, due to the enlarging and complexity of networks. A series of breakdown have emerged from physical connection failure, software connect to viral network. Scanner tool also arises at the historic moment.This thesis mainly aims at embedded platform of network ARM9hand-held scanner tool with the layering design as leading ideas. As the requirements of the thesis, to seprate the support of hardware platform and the realization of the function of software. The system’s flexibilty and expansibility can be improved. Qt/Embedded Linux UI library is used as the function of the library, soft UI program to run through the least changes in other platforms.The thesis is divided into two parts, system platform and the system software. And the system platform has five stages for transplants, Linux kernel Boot loader points transplants, file system construction, and transplant and graphical interface Linux platforms environment building library transplantation. But the system software is divided into six modules. The program modules, input control module,system setup program modules, and storage device antivirus/immune program modules, based on the Ping target connection and testing program modules and the ARP deception detection program modules. Through the multi-level division, all function of system’s development and testing become more independence and reduce the difficulty of the system maintenance.In addition, system design is discussed from the general design and detailed design, and this article explains the realization of the system in detail. The application of white box testing and black box testing are used in stage, and through testing to detect whether the system can work for each function, and also the system’s overall status. Test results show that the system achieved all the functions and the whole system work in good condition.
