Abstract

The invention discloses an LED vehicle lamp driver online detection system, which belongs to the technical field of intelligent detection. The LED vehicle lamp driver online detection system comprisesa data acquisition control system, a linear guide rail and tooling. The LED vehicle lamp driver online detection system can test the performance of an LED vehicle lamp driver, controls the on / off ofthe LED vehicle lamp driver by means of a CAN bus, tests signals of various paths of currents in the LED vehicle lamp driver by adopting a current card, can set threshold values of the tested signalsindependently, and alarms to notify a tester to check cause of a fault when the acquired signals exceed the set threshold values, thereby improving the detection coverage and precision of the LED vehicle lamp driver, being reliable in equipment and easy to operate, and greatly improving the reliability of product manufacturing quality.

Description

technical field [0001] The invention belongs to the technical field of intelligent detection, in particular to an on-line detection system for an LED lamp driver. Background technique [0002] With the rapid development of the automobile industry at home and abroad, automobile lights are developing from a single lighting function to a multi-functional and intelligent direction. Halogen lamps are gradually replaced by LED lamps as traditional car lighting means, and LED car lamp drivers can realize more complex functions of headlights by intelligently controlling the changes of LEDs. As an important tool for safe driving and lighting of automobiles, performance testing of LED lamp drivers is extremely important. The general detection method only tests the internal circuit of the lamp driver, and detects the on-off and welding reliability of the circuit. However, the performance test of the LED car light driver is insufficient, and the function test of the car light driver i...
