Abstract

The utility model discloses a kind of LED display light signal test system, the utility model shows a certain state of the display screen on each testing jig in test by the signal lamp of each different colours in signal lamp group, it is not only directly perceived eye-catching, and manual record is not had to, greatly reduce to artificial requirement, and it is not error-prone.

Description

LED display light signal test system

Technical field

A kind of test system is the utility model is related to, particularly a kind of LED display light signal test system.

Background technology

With making rapid progress for Information Technology Development, LED large screen displays have been applied to the every field of our lives, Common LED giant-screens are used to show word or pattern by luminescence pixel array, are mainly used in outdoor advertising and show, each Giant-screen is combined by some display modules, and some trichromatic LED conducts of array in each display module Light emitting pixel.All have to do various detections before each piece of display screen dispatches from the factory, including detection light emitting pixel either with or without Uneven, luminous dim spot of aberration, color etc., usually require module being fixed on a testing jig to combine for the ease of detection Entirety into display screen is used to test, consequently facilitating pinpointing the problems, but colour signal survey is fitted without on former testing jig Test system, thus the module on the testing jig specifically can only be recorded manually in what kind of test process, if surveyed Examination frame can also be completed less, but be usually constructed with tens testing jigs and test, thus manually writing task amount is big, Er Qierong It is error-prone.

The content of the invention

For overcome the deficiencies in the prior art, the utility model provides a kind of LED display light signal test system.

Technical scheme is used by the utility model solves its technical problem：

LED display light signal test system, it is characterised in that：Including

Control module,

Signal lamp group, signal lamp group include：The greensignal light of burn-in test is being carried out for expression, in expression aging Test the red eye of completion, for representing to be in the amber lamp of artificial detection state after the completion of burn-in test, being used for Represent the blue signal lamp that artificial detection is completed；And red eye, greensignal light, amber lamp, blue signal lamp are equal Electrically connect and be controlled by it with control module,

AC relay, electrically connected with the power supply driver in control module and LED module, and control module can control The break-make of AC relay controls the break-make of power supply driver and extraneous power supply,

Check valve, electrically connected with control module, and including three mode bits：Detecting position, detection complete position and close inspection Location, by control module amber lamp can be controlled bright when it is located at detecting position；It can lead to when it is positioned at detection completion position It is bright to cross control module control blue signal lamp, amber lamp and indigo plant can be controlled by control module positioned at when closing detecting position Chrominance signal lamp goes out,

Timer, electrically connected with control module, and the break-make of AC relay and green can be controlled by control module The light on and off of chrominance signal lamp, red eye.

The control module is a MCU chip.

The beneficial effects of the utility model are：The signal lamp that the utility model passes through each different colours in signal lamp group It is not only directly perceived eye-catching to show a certain state of the display screen on each testing jig in test, and do not have to manual record, Greatly reduce to artificial requirement, and it is not error-prone.

Brief description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is theory diagram of the present utility model.

Embodiment

Reference picture 1, the utility model discloses a kind of LED display light signal test system, including control module, control Molding block is a MCU chip, signal lamp group, and signal lamp group includes：For represent carrying out burn-in test greensignal light, Believe in the red eye that expression burn-in test is completed, for the yellow in artificial detection state after the completion of representing burn-in test Signal lamp, the blue signal lamp completed for representing artificial detection；And red eye, greensignal light, amber lamp, blueness Signal lamp is electrically connected and is controlled by it with control module, AC relay, with the power drives in control module and LED module Device electrically connects, and control module can control the break-make of AC relay to control the break-make of power supply driver and extraneous power supply, Check valve, electrically connected with control module, and including three mode bits：Detecting position, detection complete position and close detecting position, its position By control module amber lamp can be controlled bright when detecting position；It can pass through control module when it is positioned at detection completion position Control blue signal lamp bright, amber lamp and blue signal lamp can be controlled by control module positioned at when closing detecting position Go out, timer, electrically connected with control module, and the break-make and green of AC relay can be controlled by control module The light on and off of lamp, red eye.

In above-mentioned, check valve, timer, AC relay and MCU chip are the conventional components of this area, exchange Relay can select the JS11 models of Zhengtai Electric Appliance Co., Ltd., Zhejiang；Timer can select the just safe electrical equipment stock in Zhejiang The JZC4 models of part Co., Ltd；MCU chip can select auspicious Sa electronics（China）The R7F0C011 models of Co., Ltd；Examine Switch as common knob electric switch.

The system principle is sketched：Display screen needs first to carry out burn-in test, first starts timer and determines the burn-in test time, Timer signals to control module simultaneously, starts AC relay and greensignal light, AC relay by control module Switch on power driver and extraneous power supply, and LED module is started working, and greensignal light lights expression just in burn-in test；In advance Fix time after arrival, timer signals to control module, closes AC relay and greensignal light by control module, together Shi Kaiqi red eyes, burn-in test terminate and lighted with red eye to notify that testing staff comes artificial detection；Detection Check valve is got to detecting position by personnel, and now check valve starts yellow by control module and believed to signal to control module Signal lamp, amber lamp it is bright represent testing staff just artificial detection LED module after burn-in test either with or without sealing-off, cracking, Phenomena such as short-circuit or breaking, after the completion of testing staff's detection, check valve can be got to detection if having no problem and complete position, Blue signal lamp is started by control module, blue signal lamp is bright to represent that testing staff detects completion, and other workers can after seeing So that the LED module on testing jig to be pick-uped, check valve is then got into closing detecting position, check valve gives control mould to signal Block closes blue signal lamp by control module, and whole detection terminates.

A kind of LED display light signal test system provided above the utility model embodiment, carry out in detail Thin to introduce, specific case used herein is set forth to principle of the present utility model and embodiment, above example Explanation be only intended to help and understand method and its core concept of the present utility model；Meanwhile for the general technology of this area Personnel, according to thought of the present utility model, there will be changes in specific embodiments and applications, in summary, This specification content should not be construed as to limitation of the present utility model.
