Abstract

The invention discloses a circuit board testing system and belongs to the field of electronic measurement. The circuit board testing system comprises a slot-0 controller, a PXI bus, a PXI testing module, a testing interface and a tested circuit board; the slot-0 controller is for control, signal interaction and data processing of a measurement test stand; the PXI testing module is used for testing according to function characteristic indexes of the tested circuit board; the PXI bus is used for signal transmitting between the slot-0 controller and the PXI testing module; the testing interface is used for placing the tested circuit board; the slot-0 controller controls the PXI testing module to perform fault diagnosis and performance testing on the tested circuit board which is fixed on the testing interface. The circuit board testing system can achieve automatic testing of integral functions and performance of a PCB (Printed Circuit Board), can provide a measurement report for measure workers and is short in testing period and accurate in testing result.

Description

technical field [0001] The invention relates to the field of electronic measurement, in particular to a circuit board testing system. Background technique [0002] PXI (PCI extensions for instrumentation) refers to PCI extensions for instrumentation systems, and is a PC-based measurement and automation platform. CAN bus (Controller Area Network) is the abbreviation of Controller Area Network, and it is one of the most widely used field buses in the world. GPIB bus (General-Purpose Interface Bus) refers to the general-purpose interface bus. Most desktop instruments are connected to PCs through GPIB lines and GPIB interfaces. [0003] In the process of assembling each PCB circuit board, testing is required to ensure that the PCB circuit can work normally. For example, a motor drive controller needs to conduct a large number of tests on its performance and functions. Traditionally, some separate measuring instruments are used. Manually measure one by one, read the pointer dat...
