Abstract

The invention relates to the technical field of lamp testing, and aims to provide a DMX lamp power-on self-test system. The DMX lamp power-on self-test system comprises a lamp detection device, the lamp detection device is connected with a to-be-detected lamp and further connected with a camera, the lamp detection device is controlled to output a DMX signal to the to-be-detected lamp, the to-be-detected lamp is driven to work, the camera collects working image information of the to-be-detected lamp and transmits the collected working image information of the to-be-detected lamp into the lamp detection device, the lamp detection device receives the working image information of the to-be-detected lamp and compares the working image information with an image preset threshold range, and when the received working image information of the to-be-detected lamp does not accord with the image preset threshold range, the lamp detection device outputs a current lamp disqualification electric signal. The DMX lamp power-on self-test system has the effects of improving the missing detection condition of DMX lamp detection and improving the detection efficiency.

Description

technical field [0001] This application relates to the technical field of lamp testing, in particular to a DMX lamp power-on self-inspection system. Background technique [0002] The LED system consists of many lamp beads. If the brightness of a certain lamp is abnormal, it will cause quality problems of the lamp beads, and even lead to the substandard quality of the entire LED system. Therefore, it is necessary to carry out strict inspection before leaving the factory. [0003] In the process of production and inspection, due to the large number of samples to be inspected, heavy workload, time-consuming and labor costs, the DMX method can be used to inspect the lamps. [0004] The DMX512 protocol was first developed by the American Theater Technology Association as a way to control the dimmer with a standard digital interface from the console. It is an industry standard for data transmission between lighting controllers and lighting equipment. DMX512 adopts the bus paral...
