Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, completeSite preparation describes it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on thisEmbodiment in invention, the every other reality that those of ordinary skill in the art are obtained under the premise of not making creative workApply example, broadly fall into the scope of protection of the invention.
A kind of as shown in Figure 1 LED string address detection system of the present invention, include control unit 1, driving test module 2,LED string 3, memorizer 4, image collecting device 5 and picture recognition module 6.
Drive test module 2, electrically connect with control unit 1, drive lamp bead work to be identified in LED string 3 or LED string 3Make；Drive test module 2 to include Carrier, this Carrier sends test signal to LED string 3, drive LED string 3 work respectivelyMake or lamp bead to be identified work.Test module 2 is driven also to be electrically connected with power supply 7, for driving test module 2 to provide power supply.
LED string 3, electrically connects with driving test module 2, accepts the work shape driving test module 2 to control LED string 3State.
Memorizer 4, is electrically connected with control unit 1, for storing the address of target lamp bead；This memorizer 4 is target lamp beadAddress give new numbering, realize each of LED string 3 LED lamp bead is identified, be easy to the control to LED string 3System.
Image collecting device 5, for gathering the working condition image of LED string 3 or lamp bead to be identified in LED string 3Working condition image, and the working condition image of the working condition image LED string 3 or lamp bead to be identified sends image knowledge toOther module 6.Image collecting device 5 includes photographic head or photographing unit or other image capture device.
Picture recognition module 6, for identifying the working condition of lamp bead to be identified in LED string 3, obtains the ground of target lamp beadLocation；, as with reference to image, in LED string 3, the working condition image of lamp bead to be identified is permissible for the working condition image of LED string 3For the image to be identified of one of LED lamp bead, image to be identified is contrasted with reference to image, can be obtained to be identifiedPosition in LED string 3 for the LED lamp bead, is easy to renumber.
