Luggage box light automatic detection device and detection method thereof

Abstract

The invention relates to an automatic detection device for a trunk lamp. A mounting seat is mounted in a test area, and an electric push rod for controlling a key switch of the trunk lamp is arranged at the upper part of the mounting seat; an illumination sensor is arranged on one side of the mounting seat and connected with a data acquisition card via an illumination measuring plate for performing AD (Analog-Digital) conversion on illumination, the data acquisition card and an isolating DIO (Digital Input Output) card are connected with an industrial control computer via a PCI (Peripheral Component Interconnection) slot, the industrial control computer acquires the current value of the illumination sensor via the data acquisition card, the industrial control computer is connected with a programmable power supply via a USB (Universal Series Bus) bus, the programmable power supply is connected with a relay control board, one end of a digital multimeter is connected with the industrial control computer via a USB data wire, while the other end is connected with the relay control board, the industrial control computer is connected with the relay control board and a micro switch control board via the isolating DIO card, and the industrial control computer is further in communication connection with a human-computer operating interface and a display. The automatic detection device can be used for automatically detecting various parameters of the trunk lamp.

Description

Technical field [0001] The invention relates to an automatic detection device for luggage compartment lights and a detection method thereof, which belong to the technical field of automatic detection of vehicle lamps. Background technique [0002] With the continuous development of the automotive industry and electronic technology, the frequency of use of intelligent and multi-function car lights in modern cars has continued to increase. Following this, the detection of various performance indicators of car lights has also become diversified and complicated. the trend of. [0003] CN 204556802 U provides an LED car light detector, which adopts a voltage and current sampling unit to pass through a communication module, and displays the sampling results and judgment results on a touch screen to automatically determine whether the current constant voltage of the tested product conforms to Factory standard. CN 102944852 A discloses a test device for testing an LED lamp matrix. The me...

Problems solved by technology

[0004] In the above-mentioned existing technical solutions, all can only perform single-function detection on the working voltage, current, illuminance or light intensity of the car lights, and the degree of automation is not high, which is increasingly unable to meet the development of modern car lights.

[0005] For the new structure of the trunk light, when it is necessary to test the six functions of the trunk light, three-speed flashlight function switching, static current, charging management, trunk light anti-reverse connection, and charging function anti-reverse connection during the research and development stage, the existing test method The test is carried out through the cooperation of professional testers and measuring equipment, but due to the existence of human factors, it is easy to cause false or missed measurements, and the testers need to undergo professional training, which will increase labor costs and time costs, which seriously affects the research and development of lamps and lanterns.
