Abstract

The utility model provides a LED vision detection system, includes a camera, board, this image information who is surveyed the LED lamp state of board of this camera collection are surveyed to a test host computer and a quilt, this test host computer contains: a sample image acquisition functional module, the LED image information of the sample device of gathering this camera handles, and the data that generate a format are as a sample data, a data storage module saves this sample data, the analysis is carried out to the board image information that is surveyed who gathers to a data analysis processing capacity module to contrast the data that obtain with this sample data, a daily record functional module, the record shows this quilt survey board LED lamp real -time status information and test result. The utility model discloses only need purchase a USB ( universal serial bus ) and exempt from to drive the digital vedio recording head, compare the intelligent camera who purchases the specialty, greatly reduced the cost. In addition outer needle only need sample to the board of different specifications again, alright realize automated inspection, it is convenient to maintain, applicability is better.

Description

LED vision detection systems

Technical field

This utility model is related to a kind of detecting system, more particularly to a kind of LED vision detection systems.

Background technology

LED tests are initially by way of testing staff is interacted with test program, i.e., manually to estimate to realize, this Used by estimation mode, the time is longer.Fool proof is realized to improve measuring accuracy, generally using a kind of LED automatic tests scheme： Behind testboard, light collection device is installed in LED concentration zones, LED light is guided and an array plane is concentrated on, by regarding Feel that detecting system (comprising professional photographic head, logic programmable controller and test main frame) carries out the state inspection of LED on and off Survey, i.e., test main frame is sent by Serial Communication Program and wants test command to logic programmable controller (PLC) is arrived, then PLC Test signal is delivered to into professional photographic head, the feedback of a lamp on/off after professional photographic head analyzes the state of LED, is given Signal is given to PLC, and then signal is fed back to test main frame by PLC again, and test main frame receives the PASS/FAIL signals of the PLC. The vision detection system that this scheme is adopted needs the professional photographic head of purchase and logic programmable controller, with high costs, uncomfortable Close a large amount of use.In addition, when the specification of tested board changes, needing again maintenance serial port communication program to examine to update the vision Examining system.

The content of the invention

For above-mentioned situation, the purpose of this utility model is to provide a kind of LED vision detection systems with low cost, also The effect to each LED state detection of tested board can be reached.

To reach above-mentioned purpose, this utility model provides a kind of LED vision detection systems, including a photographic head, a test Main frame and a tested board, the photographic head gather the image information of the LED state of the tested board；The test main frame is included：

One sample image collecting function module, the image information of the sample device LED state collected to the photographic head are entered Row is processed, and automatically generates a kind of data of formatting, as a sample data；

One data memory module, stores the sample data after the LED state image information is formatted；

One Data Analysis Services functional module, the tested board image information to collecting in test process are divided in real time Analysis, and the data for obtaining are carried out into real time contrast with the sample data in memory module；

One journal function module, records and shows the tested board LED real time status information and test result.

Compared to prior art, this utility model need to only purchase a USB（USB (universal serial bus)）Free drive digital camera head, phase Intelligent video camera head than purchasing specialty, greatly reduces cost.Otherwise for the board of different size, need to only re-start and adopt Sample, is just capable of achieving automatic detection, and easy to maintenance, wide usage is more preferable.

【Description of the drawings】

Fig. 1 is the structured flowchart of an embodiment of LED vision detection systems of the present utility model.

【Specific embodiment】

Refer to shown in Fig. 1, be the structured flowchart of an embodiment of LED vision detection systems of the present utility model.The LED Vision detection system includes photographic head 10, test main frame 20 and tested board 30.The tested board 30 LED measurement jigs are provided with And module to be measured.The photographic head 10 is used for collection by light collection device 30 each LED of tested board that for example light guide plate transmission comes The image information of lamp state.The test main frame 20 includes sample image acquisition function module（Auto Learning）21st, data are deposited Storage module 22, Data Analysis Services functional module 23 and journal function module 24.Before testing, debug a tested board 30 to make For sample device, LED vision detection systems of the present utility model first by the sample image acquisition function module 21, using taking the photograph As a LED state for 10 pairs of tested boards 30 carries out sample image information gathering and is converted into a sample data, the sample data Including LED numbers, LED location (X, Y-coordinate), LED luminance and LED state（Chang Liang, often go out or flash）, then by data Memory module 22 stores the sample image data, and the tested board of same specification only needs capturing sample image once.Follow-up In test process, LED state image of the Data Analysis Services functional module 23 using the tested board of 10 Real-time Collection of photographic head 30 Information, while recognizing the rgb value of image bit map pixel, and the measured data for obtaining is contrasted with the sample data, is detected Whether the measured data is consistent with sample data（Or whether difference is within the scope of rational）.The journal function module 24 is remembered The LED real time status information and test result of the lower tested board 30 of record.Meanwhile, if detection passes through, the journal function The prompting testing staff's detection of module 24 passes through, if detection does not pass through, abnormal LED state is shown by the journal function module 24 Show to testing staff, point out not pass through and exit detection.

Specific embodiment of the present utility model and embodiment are elaborated above in conjunction with accompanying drawing, but can not be with it Scope of the present utility model is limited, the impartial modification and transformation made in this utility model claim should all belong to In this utility model the scope of the claims.
