Abstract

The invention discloses a pulse immunity automatic test system and a method. The invention belongs to the technical field of pulse immunity testing systems. The system comprises a group pulse signal generator, a power amplifier, a pulse emission probe, a probe clamp, a robot, an industrial camera, a test computer and a tested object, the test computer is bidirectionally connected with the robot and the industrial camera, a test area is positioned by using high resolution of the industrial camera, and each point position of an actual tested area is obtained to schedule the robot to accurately move; the test computer is connected with the group pulse signal generator to control the group pulse signal generator to emit a group pulse interference signal through the pulse emission probe, and aninterference source is manufactured to interfere a tested object. The interference problem caused by the electrical fast pulse signal is tested and analyzed, and an effective means is provided for solving the group pulse interference problem.

Description

technical field [0001] The invention relates to the technical field of pulse immunity testing systems, in particular to an automatic testing system and method for pulse immunity. Background technique [0002] The present invention is mainly aimed at the automatic test system for the interference of electric fast pulse disturbance signal (EFT) on the product. The system adopts the automatic test mode of the robot and presents a friendly interface, so as to better find the disturbed source. To solve this problem, it is necessary to simulate the interference risk in the actual scene, accurately analyze the anti-EFT ability of related devices and components, and provide users with an effective tool for quickly analyzing and solving EFT interference problems. [0003] With the continuous deepening of the Internet of Everything and the rapid development of electronic products, in the electromagnetic compatibility reliability design, it is necessary to solve the electrical fast tra...
