Dual-line cascade application system and implementation method thereof for simultaneously supplying electrical power and transmitting data

A dual-line cascade application system for simultaneously supplying electrical power and transmitting data, including a controller, cascade chips connected to the controller, and LED lights connected to the cascade chips. Each cascade chip is provided with a voltage clamp module, an electrical power supply module, a data storage module, a PWM constant current output driving circuit, an R end (Red LED output end), a G end (Green LED output end), a B end (Blue LED output end), a W end (White LED output end), a VCC/DATA end and a GND/DATA end, as well as a data sampling and calibration module, a power line data sampling and transmission module, a chip initial address setting by command module, a module which determines if E-fuse address of the chip is identical to an address of received data, and an E-fuse module which are sequentially connected. A method using the system is also provided.
