Fig. 2 is the led display unit structured flowchart.This led display unit comprises: power input 7 and 8; Power output end 10 and 11; Control chip 4; Signal input part 9 links to each other with control chip 4 inputs by protection device 5; Signal output part 12 links to each other with control chip 4 outputs; Emitting red light device 13 links to each other with control chip 4; Blue luminescent device 14 links to each other with control chip 4; Green light emitting device 15 links to each other with control chip 4; Power adjustment device 6, connect and power supply and control chip 4 between, play the effect of voltage stabilizing; One protection device 5 is connected between signal input part 6 and the control chip 4, and this protection device 5 is lightning protection or antistatic device.
In conjunction with Fig. 1 and Fig. 2, be that example describes described diode network control system with led display unit 30.Controller 1 is encoded to control signal according to user's instruction, control signal after controller 1 will be encoded is exported by holding wire, control chip 4 in the led display unit 31 is by signal input part 6 picked up signal, 4 pairs of received control signals of control chip are handled, the control signal that receives this unit is also temporary, afterwards follow-up control signal is delivered to led display unit 31 by signal output part 12.Temporary control signal is sent to the control that emitting red light device 13, blue luminescent device 14, green light emitting device 15 are realized led display unit brightness, color etc. in control chip 4.Control signal enters led display unit 31 and does same processing, and in like manner, this system can connect led display unit many, and the control signal of this unit is preserved in each unit, and follow-up control signal is delivered to next led display unit by signal output part.
The realization key of described diode network control system is the coded system to the light data; In this coded system, comprised data message and clock information, can make led display unit from data, recover synchronised clock, and accurately receive data according to clock.
Use Manchester (manchest) coded system to realize in the first embodiment.Controller 1 is encoded to control signal by the Manchester's code rule, and control chip 4 is decoded to control signal by the manchester decoder rule.
Joseph Levis spy (laivist) coded system realizes in second execution mode.Controller 1 is encoded to control signal by the special coding rule of Joseph Levis, and control chip 4 is decoded to control signal by Joseph Levis particular solution sign indicating number rule.
Each the control data of led display unit be the N position, each series connection of root cable M led display unit, then the N*M position, an auspicious video data position on this data wire.
Transmit with Manchester's code in the first embodiment: LED lamp controller 1 with video data with one auspicious be that unit sequence sends.Each is auspicious begins to send a trailing edge is beginning flag, then N*M position LED video data is carried out uninterruptedly sending successively after the Manchester's code, send the N position of first led display unit 30 earlier, send the N position of second led display unit 31 again, up to the data of having sent M led display unit, auspicious data send and finish back minimum three high level of maintenance as auspicious end mark.Led display unit enters reception decoding state after detecting the trailing edge beginning flag, begins to receive data and the data counts to receiving, and utilizes trailing edge or rising edge calibration synchronised clock simultaneously.When being, N sends the beginning flag of a trailing edge when receiving as next led display unit, after receiving the N bit data of this unit, video data is temporary to led display unit control chip 4, will send to next unit after the follow-up video data shaping simultaneously.After receiving continuous late high level end mark, the count pick up device that resets prepares to receive next auspicious data.
In second execution mode with the special coding transmission of Joseph Levis: the LED lamp controller with video data with one auspicious be the unit sequence transmission.N*M position LED is shown that control data carries out uninterruptedly sending successively behind the special coding of Joseph Levis, send the N position of first led display unit 30 earlier, send the N position of second led display unit 31 again, up to the data of having sent M lamp, auspicious data send and finish back minimum three high level of maintenance as auspicious end mark.Led display unit enters reception decoding state after detecting the trailing edge beginning flag, begins to receive data and the data counts to receiving, and utilizes trailing edge calibration synchronised clock simultaneously.After receiving the N bit data of this unit, video data is temporary to led display unit control chip 4, will send to next unit after the follow-up video data shaping simultaneously.After receiving continuous late high level end mark, the count pick up device that resets prepares to receive next auspicious data.
