Description
Technical field
It is that power-line carrier communication, the internet communication technology and movement are logical the present invention relates to field of communication technology
The technology that letter technology combines.
Background technique
With the continuous development of artificial intelligence technology, the demand remotely controlled is more and more, and the communication of signal has become as people
The important component of work intellectual technology.Signal is directly transmitted using power line is undoubtedly both economical practical method.Electric power
Line carrier communication technology comes across phase early 1920s.The skill of carrier communication on the transmission line of electricity of 10kV above
Art is quite mature.But the power carrier communication on 380V/220V low voltage electric network is all undesirable always.Especially in recent years,
Since the equipment of carrying is too many, noise and interference are too big on power grid, have been difficult the channel for being taken as signal to transmit.Present invention fortune
With with conventional electric power carrier communication entirely different principle and method, the electric power achieved on 380V/220V low voltage electric network is carried
The technological break-through of wave communication, realizes the transmission of the communication signal under high-noise environment.At present have reached signal real-time Transmission and
It receives, stable signal transmission, without interfering with each other, can be used for equipment control.The present invention is a kind of wisdom agriculture based on power carrier
Industry Internet of Things bridge is the bridging device capable of being connected of internet signal and power line carrier signal.Through the invention by power line carrier, PLC, mutually
Connected network communication and mobile communication combine, and so that electrical equipment online is become simple and fast, decline the cost of Internet of Things.It is especially suitable
For wisdom agriculture field.
Summary of the invention
A kind of wisdom agricultural Internet of Things bridge based on power carrier its by lead (1), DC power supply (2), cable network core

It connects, lead (1) connects with DC power supply (2), coupling circuit (7) respectively.Lead (1) is metallic conductor, with 220V alternating current
It is connected.DC power supply (2) is the device of low-voltage DC needed for providing work for this system other devices, output 12V and
The direct current of 14V voltage.Cable network chip (3) is built-in with data protocol management conversion program, is responsible for cable network and electricity
Data in powerline networks carry out the two-way transparent transmission of the coordinating and unifying, and are filtered to communication data and the device of traffic organising
Part.Router (4) is to automatically select and set routing according to the case where channel, with optimal path, sends and believes by tandem
Number, with cable interface.Turn in power line carrier, PLC chip (5) comprising automatic gain device, automatic gain controller, analog/digital
Parallel operation, digital filter, central processing unit, D/A converter, signal output filter.In in power line carrier, PLC chip
Central processor is equipped with carrier communication software.Power amplification circuit (6) is to carry out to the signal that power line carrier, PLC chip issues
The device of amplification.Coupling circuit (7) are the circuits of inductance capacitance composition, signal on low-voltage circuit can be coupled to high-tension circuit
On or high-tension circuit on signal be coupled on low-voltage circuit.Oscillator (8) can be used oscillating circuit and be placed among chip,
