out outer extension based on 32-bit microcomputer S3C2410A. It includes signal collection, signal adjust circuit, JTAG

interface, LED display, wireless card interface and RS 232 interface. Then, the data of large-scale weapon equipment was

collected and the ireless data of up PC was interacted. The up PC is consisted of wireless configure wireless network card

PC. The hand PC was adopted to receive information gathered by low PC and display through wireless network card.

Through calling database, the data was analyzed to find out the reasons of diagnosis.
