Background technique
With the continuous development of artificial intelligence technology, the demand remotely controlled is more and more, and the communication for controlling signal has become
For the pith of artificial intelligence technology.Most economical method is undoubtedly using the direct transmission of control signals of power line.This side
Method is referred to as electric line carrier communication.
Power-line carrier communication comes across phase early 1920s.On the transmission line of electricity of 10kV above
The technology of carrier communication is quite mature.But the power carrier communication on 380V/220V low voltage electric network is all paid no attention to always
Think.Especially in recent years, since the equipment of carrying is too many, noise and interference are too big on power grid, have been difficult that signal is taken as to transmit
Channel.The present invention has used and conventional electric power carrier communication entirely different principle and method, achieves 380V/220V low pressure
The technological break-through of power carrier communication on power grid realizes the transmission of the communication signal under high-noise environment.It has reached at present
Signal real-time Transmission and reception, stable signal transmission can be used for equipment control without interfering with each other.The present invention be directed to this carrier waves
The disclosure of smart projector technology in technology.The projector is bridged by the Internet of Things on power line into network, then passes through net
Network server is connected with the computer of the network other end or mobile phone, computer or the remote controlled projector of mobile phone.
