The method is characterized in that a power line carrier concentrator and a power line carrier control node are provided with a harmonic noise sensor, transmitting signals comprise harmonic noise parameters, the harmonic noise parameters subjected to conductive transformation in receiving signals are filtered out, and the transmitting terminals and the receiving terminals are appointed to firstly transmit a conductive transformation relation before communication. According to the method provided by the invention, influences of low-voltage power grid harmonic noise to power line carrier transmission quality and transmission distance are effectively reduced.
Description
Technical field
The invention belongs to power carrier field, is related to the elimination of power carrier resonant noise, a kind of especially fixed transmitting-receiving place
The method of power carrier harmonic carcellation noise jamming.
Background technology
Power line carrier Power Line Carrier-PLC communication be by the use of electric lines of force as information transmitting medium carry out voice or
A kind of specific communication mode of data transfer.Electric lines of force is generally divided into high, normal, basic 3 class, usual high-tension electricity in power carrier field
Line refers to that 35kV and above, medium voltage power line refer to 10kV electric pressures or low-voltage distribution wire 380/220V user's line.This
The occasion that invention is suitable for is the situation of 380/220V under low-voltage distribution.
PLC is Power Line Carrier, and power line carrier (PLC) is the distinctive communication mode of power system, and electric lines of force is carried
Ripple is communicated and is referred to using existing electric lines of force, and analog or digital signal is carried out the technology of high-speed transfer by carrier system.It is maximum special
Point is need not to set up again network, as long as live wire, can just carry out data transfer.
But power carrier interference in actual use usually because of harmonic noise, causes transmission range to shorten, or receive
The situation of transmission signal distortion, such case leverage the application popularization of power carrier.
The content of the invention
It is an object of the invention in place of overcoming the deficiencies in the prior art, there is provided one kind can effectively reduce low voltage electric network harmonic noise
The method affected by electric force carrier transmission quality and transmission range.
The technical proposal for solving the technical problem of the invention is:
A kind of method of the power carrier harmonic carcellation noise jamming in fixed transmitting-receiving place, including the power carrier that a position is fixed
The power carrier receiving terminal that transmitting terminal and multiple positions are fixed, power carrier concentrator and power carrier control node carry harmonic wave and make an uproar
Sonic transducer, includes harmonic noise parameter, filters the harmonic noise parameter through conduction transformation in receiving signal in sending signal,
Before communication, transmitting terminal and receiving terminal agreement are using first transmission conduction transformation relation.
And, described conduction transformation is measured in advance.
Advantages of the present invention and good effect are:
This method effectively reduces impact of the low voltage electric network harmonic noise to electric force carrier transmission quality and transmission range.
Specific embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, be not it is determinate,
Protection scope of the present invention can not be limited with this.
A kind of method of the power carrier harmonic carcellation noise jamming in fixed transmitting-receiving place, including the power carrier that a position is fixed
The power carrier receiving terminal that transmitting terminal and multiple positions are fixed, power carrier concentrator and power carrier control node carry harmonic wave and make an uproar
Sonic transducer, includes harmonic noise parameter, filters the harmonic noise parameter through conduction transformation in receiving signal in sending signal.
For fixed transmitting-receiving occasion, its conduction transformation can be to measure in advance.
Above-described is only the preferred embodiment of the present invention, it is noted that for the person of ordinary skill of the art,
On the premise of without departing from inventive concept, some deformations and improvement can also be made, these belong to protection scope of the present invention.
