The present invention is described in further detail.
Fig. 1 is a kind of flow chart of the synchronous method of network clocking provided in an embodiment of the present invention；Fig. 2 is that the present invention is implemented
The schematic diagram for the zero cross signal that example uses.As shown, a kind of synchronous method of network clocking includes：
S10：Obtain the zero cross signal of the zero cross signal and remote equipment of local device.
It is understood that the power generation of electric system, transmission of electricity, power transformation and controller switching equipment and industry and civil electrical equipment
It is all made of rated frequency, this rated frequency is extracted, in voltage be signal near 0 is zero cross signal.In alternating current system
In system, zero passage equipment detects that the signal sent out when voltage zero-crossing point of power grid is zero cross signal.
It please refers to Fig.2, it should be noted that since the zero cross signal of current each plant equipment is as carrier communication
Reference, carrier frequency is relatively low, not high to zero cross signal required precision, generally in millisecond (ms) rank, but this implementation
The precision of zero cross signal required in example is higher namely what the present embodiment obtained is high-precision zero cross signal, generally in microsecond
(us) rank.The present embodiment does not limit the concrete mode for obtaining the zero cross signal of local device and the zero cross signal of remote equipment
It is fixed.It is further to note that since the zero cross signal of the present embodiment extraction is the intrinsic zero cross signal in electric system, namely
Zero cross signal is feature of power grid in electric system itself, therefore need not send in other signals to electric system and be obtained
It takes, therefore electric system will not be interfered, reduce the cost and complexity of system.
S20：According to the zero cross signal of the zero cross signal of local device and remote equipment correspond to generate local reference clock and
Distal end reference clock.
Specifically, according to the zero cross signal of local device generate local device clock source, recycle local device when
Zhong Yuan generates local reference clock；Correspondingly, generating the clock source of remote equipment according to the zero cross signal of remote equipment, recycle
The clock source of remote equipment generates distal end reference clock.
S30：Judge whether distal end reference clock and local reference clock are corresponding synchronous network clock.
Specifically, due to being to obtain zero cross signal from local device and remote equipment respectively, further according to the mistake of local device
The zero cross signal of zero-signal and remote equipment, which corresponds to, generates local reference clock and distal end reference clock.Therefore, only when distal end
When reference clock and local reference clock are corresponding synchronous network clock, can just it utilize distal end reference clock to local clock
Information is adjusted.That is, needing to prejudge distal end reference clock with local reference clock whether to be corresponding synchronizing network
Clock, specifically, can be compared by pre-set comparison condition, by judging whether comparison condition meets synchronous net
The condition of network clock, to judge whether distal end reference clock and local reference clock are corresponding synchronous network clock.It needs
Illustrate, the present embodiment does not limit specific judgment mode.
It is also envisioned that local device can be one or more, that is to say, that corresponding synchronizing network can
To be the same distal end reference clock with multiple local reference clocks for corresponding synchronous network clock.
S40：If so, when judging that local clock information is inconsistent with distal end clock information, when using distal end benchmark
Clock adjusts local clock information.
Specifically, after judging distal end reference clock and local reference clock for corresponding synchronous network clock, into one
Step judges whether local clock information is consistent with distal end clock information, if inconsistent, then it represents that the local clock of local device is believed
Breath needs to be adjusted, synchronous with distal end clock information to achieve the effect that.
It should be noted that local device can receive distal end reference clock by power line carrier signal, in order to
Local clock information is adjusted using distal end reference clock, naturally it is also possible in other way, such as by radio communication
Mode, the present embodiment do not limit this.Due to the present embodiment can be using other than carrier signal other modes into
Row transmission distal end reference clock, namely it is not necessarily to special carrier, to save communication band.
It should be noted that in general, when electric on the local device, then the step of network clocking synchronization is carried out.To avoid
Other factors cause after powering on, and the local clock information of local device and the distal end clock information of remote equipment are inconsistent,
Therefore the operation of S10 to S40 can also be executed by the way that the preset time cycle is arranged.
A kind of synchronous method of network clocking provided by the invention, including obtain the zero cross signal of local device and distally set
Standby zero cross signal；When then corresponding to generation local reference according to the zero cross signal of the zero cross signal of local device and remote equipment
Clock and distal end reference clock；Judge whether distal end reference clock and local reference clock are corresponding synchronous network clock again；If
It is that then when judging that local clock information is inconsistent with distal end clock information, local clock is adjusted using distal end reference clock
Information.This programme is when local clock information and distal end clock information are inconsistent, when adjusting local using distal end reference clock
Clock information, since zero cross signal and the zero cross signal of remote equipment of the local device in corresponding synchronizing network are synchronous always
, therefore corresponding generation local reference clock also will be synchronous with distal end reference clock, can avoid passing using carrier signal
The transmission delay and delay stack that defeated synchronizing signal is brought, while avoiding the cumulative time caused by the counting of system crystal oscillator
Error, to improve accuracy and the efficiency of network clocking synchronization.
Fig. 3 is the flow chart of the synchronous method of another network clocking provided in an embodiment of the present invention.As shown in Fig. 3,
On the basis of above-described embodiment, the present embodiment has made further instruction and optimization to technical solution, specifically, judging distal end base
Whether punctual clock and local reference clock are that corresponding synchronous network clock specifically includes：
S31：Whether the taiwan area of the taiwan area and local reference clock that judge distal end reference clock is consistent.
Whether the taiwan area of the taiwan area and local reference clock that judge distal end reference clock is consistent, can be in advance in distal end base
Identification information is respectively set in punctual clock and local reference clock, is judged according to identification information.As preferred embodiment,
It can judge whether the signal characteristic of distal end reference clock meets preset item by the signal characteristic of extraction distal end reference clock
Part, for example, by from the signal characteristic and local device extracted in the reference clock of distal end pre-stored signal characteristic compare
Compared with, when the signal characteristic of distal end reference clock with pre-stored signal characteristic is consistent in local device when, indicate distal end benchmark
The taiwan area of clock is consistent with the taiwan area of local reference clock.It should be noted that the quantity of signal characteristic can be one or
Multiple, further, signal characteristic can be phase noise parameter and/or jitter parameter and/or harmonic parameters.The present embodiment
Specific signal characteristic is not limited, the feature that calculation processing is convenient, can clearly judge difference is selected in practical application
?.
S32：If taiwan area is consistent, further the phase information of distal end reference clock and the phase of local reference clock are judged
Whether information is consistent；
If phase information is consistent, enters when judging that local clock information is inconsistent with distal end clock information, utilize
The step of distal end reference clock adjustment local clock information.
It is understood that when judging that the taiwan area of distal end reference clock is consistent with the taiwan area of local reference clock, then into one
Whether the phase information for walking the phase information and local reference clock that judge distal end reference clock is consistent.
It should be noted that since there are A, B and C three-phase voltages, the phase of three-phase voltage to differ 120 ° respectively in power grid.
Therefore after generating zero cross signal, zero cross signal correspond to accordingly different phases namely zero cross signal may accordingly there is
The deviation of 20/3ms, it is corresponding to correspond to according to the zero cross signal of local device and the zero cross signal of remote equipment and generate local reference
Also there will be phase differences for clock and distal end reference clock.If when phase and local reference without judging distal end reference clock
The relationship of the phase of clock, and local clock information will be directly adjusted using distal end reference clock, then local clock is believed
Breath also will be nonsynchronous with distal end clock information.Therefore, it is necessary to judge the phase information of distal end reference clock and local reference
Whether the phase information of clock is consistent.Specifically, obtaining the phase information and local reference clock of distal end reference clock respectively
Then the phase information obtained respectively is compared by phase information.If phase information is consistent, S40 is entered step.
S33：If phase information is inconsistent, further the phase of distal end reference clock is adjusted, enters back into and is sentencing
Break local clock information and distal end clock information it is inconsistent when, utilize the step of distal end reference clock adjustment local clock information
Suddenly；
S34：Otherwise, terminate process.
Specifically, if distal end reference clock is consistent with the phase information of local reference clock, to distal end reference clock
Phase is not processed, and is directly entered step S40；If the phase of distal end reference clock and local reference clock is inconsistent, need
The phase of distal end reference clock is adjusted, step S40 is then entered back into.More specifically, to the phase of distal end reference clock
It is adjusted specially：It, will distal end in adjustment if the phase of the advanced local reference clock of the phase of distal end reference clock
The phase of reference clock reduces 120 °, if the phase of distal end reference clock falls behind the phase of local reference clock, is adjusting
When the phase of distal end reference clock increased by 120 °.It is, of course, also possible to be other adjustment modes, the present embodiment does not limit this
It is fixed.
Otherwise, illustrate that the distal end reference clock and local reference clock are not corresponding synchronous network clocks, therefore ignore
The distal end reference clock, namely terminate process.
As it can be seen that judged by the taiwan area information and phase information to distal end reference clock and local reference clock, from
And judging whether the taiwan area of distal end reference clock is corresponding synchronous network clock with local reference clock, decision procedure is simply accurate
Really.
On the basis of the above embodiments, the present embodiment has made further instruction and optimization to technical solution, specifically,
Further comprise after the zero cross signal of the zero cross signal and remote equipment that obtain local device：
The zero cross signal of the zero cross signal of local device and remote equipment is filtered respectively.
Specifically, can be filtered to the zero cross signal of local device and the zero cross signal of remote equipment by filter
Processing, filters out the invalid components in the zero cross signal got.It is understood that filtration step is in order to avoid useless
Signal component interferes subsequent signal processing, and local reference clock and distal end reference clock are generated according to zero cross signal to improve
Efficiency and accuracy.
As preferred embodiment, when judging that local clock information is inconsistent with distal end clock information, using remote
