It has the characteristics of simple equipment (only the host needs to send instructions, the slave needs to receive instructions, and no other equipment is required in the middle), customizable cutting according to the on-site application scenario and protocol, and flexible, free and changeable.

[0019] Specifically, the remote constant current receiving control circuit includes an LED driver chip U1, a light emitting diode D1, a light emitting diode D2, a light emitting diode D3, a light emitting diode D4, a light emitting diode D5, a light emitting diode D6 and a capacitor C1, the twelfth pin of the LED driver chip U1 is connected to the pulse input terminal PI via a resistor R37, the second pin, the third pin, the fourth pin, the fifth pin, the sixth pin and the seventh pin of the LED driver chip U1 are respectively connected to the light emitting diode D1, the light emitting diode D2, the light emitting diode D3, the light emitting diode D4, the light emitting diode D5 and the light emitting diode D6; the light emitting diode D1, the light emitting diode D2, the light emitting diode D3, the light emitting diode D4, the light emitting diode D5 and the light emitting diode D6 are respectively connected to resistors R1, R2, R3, R4, R5 and R6. It can be understood that the LED constant current driver chip U1 adopts the UCS512G6 chip. It can be understood that the utility model adopts multiple groups of communication constant current integrated design chips, and all LED information values ​​(including brightness value, position value, timing value, etc.) are hung on the bus through a specific (custom or customer-defined) communication protocol, and corresponding changes are made according to the controlled LED object; the transmission distance can theoretically reach 1200 meters.

[0020] Specifically, the main power supply input circuit includes power input terminal V+, power input terminal V-, capacitor C11, capacitor C12, capacitor C13 and capacitor C14, one end of capacitor C11, one end of capacitor C12, one end of capacitor C13 and one end of capacitor C14 are all connected to the power input terminal V+, the power input terminal V+ is connected to the sixteenth pin of the LED driver chip U1 via resistor R25, and the power input terminal V- is connected to the sixteenth pin of the LED driver chip U1 via capacitor C1.
