Source interface connection.
Preferably, the carrier processing chip is CR700 chip.
Preferably, the length of the current supply line is less than 2km.
As the above scheme is adopted, the main transmission box of the utility model transmits box only by current supply line auxiliary connection,
It does not need in external signal wire, can not only provide power supply using current supply line, the transmission of control signal also may be implemented, specifically
On current supply line, pair transmission box then passes through at carrier wave the control signal loading for being inputted main transmission box using carrier processing chip
Reason chip reads the control signal loaded on current supply line, to realize the signal transmission of current supply line；Meanwhile it being transmitted using pair
Lamps and lanterns working condition is fed back to main transmission box by box, and main transmission box is fed back by signal, and then user is facilitated to learn lamps and lanterns
Working condition, structure is simple, easy to operate, has very strong practicability.
