Abstract
The invention relates to a method for eliminating harmonic noise interference for power line carrier of a fixed receiving-transmitting field with a standard source. The method is characterized in that a fixed power line carrier transmitting end and a plurality of fixed power line carrier receiving ends are provided; both the power line carrier transmitting end and the power line carrier receiving ends are provided with harmonic noise sensors and standard source generators; and before communication, the transmitting end and the receiving ends appoint to transmit the standard source firstly to measure a conduction transformation relationship. Through adoption of the method, the influence of low-voltage power grid harmonic noise on the transmission quality and transmission distance of the power line carrier is lowered effectively.
Description
Technical field
The invention belongs to power carrier field, is related to the method for fixed transmitting-receiving place power carrier harmonic carcellation noise jamming, especially
It is a kind of fixed transmitting-receiving place power carrier harmonic carcellation noise jamming method with standard source.
Background technology
Power line carrier Power Line Carrier-PLC communication be by the use of power line as information transmitting medium carry out voice or
A kind of specific communication mode of data transfer.Power line 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 power line is carried
Ripple is communicated and is referred to using existing power line, 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 a kind of low voltage electric network harmonic noise that effectively reduces is to electricity
The fixed transmitting-receiving place power carrier harmonic carcellation noise jamming side with standard source that power carrier-wave transmission quality and transmission range affect
Method.
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 the fixed transmitting-receiving place with standard source, fixes including a position
Power carrier transmitting terminal and several positions fix power carrier receiving terminal, power carrier transmitting terminal and power carrier receiving terminal it is equal
With harmonic noise sensor and standard source generator, before communication, transmitting terminal and receiving terminal agreement are passed using standard source measurement is first sent
Waveguide transformation relation.
And, described transmitting terminal can synchronized transmission marking signal when standard source signal is sent.
And, described conduction transformation is measured in real time.
Advantages of the present invention and good effect are：
Before communication, transmitting terminal first sends standard source measurement conduction transformation bearing signal to receiving terminal to this method, so as to effectively reduce
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 the fixed transmitting-receiving place with standard source, fixes including a position
Power carrier transmitting terminal and the power carrier receiving terminal fixed of several positions, power carrier transmitting terminal and power carrier receiving terminal from
Band harmonic noise sensor and standard source generator, before communication, transmitting terminal and receiving terminal agreement are passed using standard source, measurement is first sent
Waveguide transformation relation, transmitting terminal can synchronized transmission marking signals when standard source signal is sent.For fixed transmitting-receiving place, its conduction
Conversion is measured in real time.
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.
