Multi-station single-parameter intelligent concurrent testing device and method for electrical characteristic parameters of LED light source products

Abstract

The invention discloses a multi-station single-parameter intelligent concurrent test device and method of electrical characteristic parameters of LED light source products. The device comprises a host, an electrical parameter measurement module, a station switch controller module and a power supply module. The host communicates with and controls the electrical parameter measurement module, the station switch controller module and the power supply module. The electrical parameter measurement module measures electrical parameters of an LED in real time and uploads the electrical parameters to the host for processing, storage and analysis. The station switch controller module is connected with a to-be-measured multi-station LED and carries out circuit switching on the accessed multi-station LED so as to connect the to-be-measured LED with the power supply module and the electrical parameter measurement module in different time. The power supply module outputs different current or voltage according to test demands. According to the invention, under the premise of ensuring that the test of the electrical characteristic parameters of LED light source products is performed according to the standard completely, scheduling is performed through an intelligent algorithm, so the multi-station concurrent test is achieved, detection time is greatly saved and detection efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of electrical characteristic parameter testing, and in particular relates to a multi-station single-parameter intelligent concurrent testing device and a testing method thereof for electrical characteristic parameters of LED light source products. Background technique [0002] LED light source products are one of the most basic components in lighting products, and their quality largely determines the quality of lighting products, so it is very important to quickly and accurately test their electrical characteristic parameters. Electrical characteristic parameter test is the main test item of LED light source product quality inspection, including rated voltage test, rated current test, rated power test, maximum limit power test, maximum allowable operating current test, maximum allowable reverse voltage test, maximum allowable pulse height test. The test process of each electrical characteristic parameter te...

Problems solved by technology

The scheduling model proposed in this article is suitable for multi-machine and multi-process job scheduling, but the establishment of the scheduling model, objective function, and constraint conditions for LED testing with a single machine and multiple processes is obviously different from the method in this article, so it is not suitable for LED testing. task scheduling
