Title  Fault detection device-specific adapter

Abstract

The progress of science made the electronic products of our society became more complex, thus automatic detection system gradually replaces the traditional inspection and maintenance way.The subject is mainly about to design a dedicated adapter hardware circuits based on general detecting platform aim at the fault detection of a radar equipment.

First, according to the needs of fault detection, the project has made the choice of the overall program of special adapter FPGA+ARM and refines the requirements of the adapter board index; ARM chip AT92SAM9G20 of ATMEL company and FPGA chip EP3SE110 of ALTERA company have been chosen as the main processer to finish the design of adapter circuit diagram; completes  a multi-layer circuit board design and PCB layout at the same time ; then tests the circuit board after processed and equipped, the test results show that the design meets the design requirements.
