Portable Fault Diagnostic System Based on Network and PDA

Abstract:

In order to solve the problem of field fault detection for engineering vehicle, we introduce a new networked portable fault diagnostic system based on PDA. The architecture of the system is presented. The system consists of dual-tier architecture. The first tier server is based on the related technical database of engineering vehicles, and the second tier one is the technical information database downloaded from the manufactures technical resources with PDA as the terminal for maintenance technician. The system function includes information query, user interaction, data downloading and uploading as well as network communication. The software platform is composed of Microsoft SQL Server Compact (SQL CE) database, application software on PDA and computer. Meanwhile the hardware platform is mainly composed of desktop PC or dedicated server, PDA mounted with cradle, data acquisition card as well as PCMCIA network adapter and so on. Both wireless communication and USB interface are adopted in the system. It has been used in many military units. The application demonstrates that the PDA-based networked fault diagnosis system of vehicles is beneficial to data query, fault elimination and repair capability of engineering vehicles.
