The specific embodiment
The present invention is described further below in conjunction with accompanying drawing.
The LED lamp string of a kind of usefulness two wires, the power circuit 8 that is provided with in the coding controller 1 connects the power supply of input, power circuit 8 output two paths of signals, one the tunnel connects CPU control module 4, another road connects transtation mission circuit 7, be respectively CPU control module 4, transtation mission circuit 7 provides operating voltage, the interface connection of CPU control module 4 correspondences is provided with carrier circuit 6, CPU control module 4 generates the pulse train signal according to different function needs, pulse signal is modulated to the signal of high frequency by carrier circuit 6, by transtation mission circuit 7 this modulation signal is sent then.
The output connection of transtation mission circuit 7 is provided with two wires 2, a plurality of LED3 are connected in parallel on two wires 2, channeling LED lamp string is provided with an identical code identification chip in the LED3 in the same paths of LEDs lamp string, be not that the set code identification chip of the LED on same road is different.As shown in Figure 1, the embodiment that connects 4 street lamp strings for the present invention.
LED3 comprises code identification chip and led chip 11, the modulation signal that transtation mission circuit 7 sends connects power circuit 8a, pulse receiving circuit 9, power circuit 8a exports two paths of signals, one the tunnel connects decoding circuit 12, another road connects on-off circuit 10, pulse receiving circuit 9 signal output parts connect decoding circuit 12, and decoding circuit 12 connections are provided with on-off circuit 10, and on-off circuit 10 outputs are arranged in parallel led chip 11.A same-code identification chip is set in each LED3 in the same road, sets in advance the recognition coding on every road in the pulse receiving circuit 9 that in the code identification chip, is provided with.At first each road is numbered, for example earlier the first via being compiled is that 1001, the second tunnel volume is 1002,, and and the like, adopt binary coding that the numbering on each road is carried out binary coding then, be that the first via is 1111101001, the second tunnel to be 1111101010 ...The coding on every road will be grown in actual use, and the pulse signal that prevents to send by the error code that interference causes of the interference of power-supply fluctuation and external pulse, is encoded too short the interference easily and caused error code in transmission course.
During the work of lamp string, in CPU control module 4, generate the pulse train signal in advance according to different function needs, pulse signal is modulated to the signal of high frequency by carrier circuit 6, by transtation mission circuit 7 this modulation signal is sent then, this moment, each paths of LEDs was all received this pulse signal, pulse receiving circuit 9 in each LED3 carries out sign indicating number after receiving this pulse signal and adopting decoding circuit 12 decodings, if the pulse signal that receives is identical with the recognition coding that sets in advance every road, then decoding circuit 12 output high level are opened on-off circuit 10, be the led chip power supply, it is luminous to control this paths of LEDs 3, if the pulse signal that receives decoding back is different with the coding that sets in advance, then do not work.The fluorescent lifetime spacing of different two paths of LED is encoded to low level 0.
Be connected respectively on the corresponding interface of the corresponding interface of CPU control module 4 and decoding circuit 12 clock circuit 5,5a are set, synchronizing datum signal is provided, guarantee that the transmission and the reception of pulse signal kept strokes.
