FPGAfield programmable gate array Precision harness inspection method using field programmable gate arrayFPGA

摘要

The present invention relates to a precision harness inspection method using an FPGA capable of precise harness inspection by applying a field programmable gate array (FPGA) technology to a state in which a line and a line are disconnected by implementing an improved ADC precision harness mounted on an FPGA board. As a main board 120 in which a Raspberry Pi 110 configured with a database (DB) and Web monitoring, a Raspberry Pi interface 121, a controller 122, an interface board interface 123, and a memory 124 are composed of an FPGA ), Each of which is divided into a plurality of channels, each of which has a disconnection check and a resistive function interface board (131, 132) is connected to the main board 120, the harness test method using a harness tester 100 configured, The power of the harness tester 100 is turned on (S100), and the Raspberry Pi 110 starts setting the test (S110), thereby executing a test (S120). ; The FPGA of the main board 120 checks the disconnection check, resistance check, and wire structure (S130, S131, S132), and the interface boards 131, 132 also perform disconnection check, resistance check, and disconnection check. (S140, S141, S142); The FPGA checks the result and stores it in the memory 124 (S150); And the Raspberry Pi 110 reading the FPGA results and storing them in the database (S160); providing a precise harness inspection method using a field programmable gate array (FPGA). do.
