Abstract
The invention discloses an electric power system telesignalling displacement dithering-removing method, and relates to the technical field of data processing; a dithering-removing period is set to reduce telesignalling interference signals; a state-stable period is set to reduce repeat sending of state displacement; a telesignalling displacement event is not generated during the dithering interference-removing period, but is generated during the state-stable period; the dithering-removing period is associated with the state-stable period so as to process interference signals with different frequencies respectively; the method can rapidly process telesignalling displacement, and reduce telesignalling displacement misinformation and missing information.
Description
Technical field
The present invention relates to data processing technique, particularly relate to the technology that electric system remote signalling frequently conjugates de-jittering method.
Background technology
In electric system, remote signalling is the significant data type representing status of electric power, and usual remote signalling state value Boolean quantity 0 and 1 represents.When electric system is broken down, remote signalling state value can frequently be shaken between zero and one, causes a large amount of shake displacement information, affects yardman's analysis and decision.Just need in this case to carry out de-jitter to data.
Summary of the invention
For the defect existed in above-mentioned prior art, technical matters to be solved by this invention is to provide a kind of electric system remote signalling displacement de-jittering method, can fast processing remote signalling conjugate, and reduces remote signalling displacement wrong report simultaneously and fails to report information.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
1) detect remote signalling state change information, if remote signalling state sends change, then record remote signals transformation period t
1, remote signalling state value v before change
0and remote signalling state value is v after change
1;
2) a Key dithering time constant T is set
dif remote signalling is at t
2in time, t here
2=t
1+ T
d, remote signalling state value reverts to v
0, then think signal disturbing, ignore this telesignalling dithering, this detects end, returns step 1); If remote signalling is at t
2time, state value does not revert to v
0, then think that remote signalling conjugates, and sends item: remote signalling is at t
1time state conjugates; Continue following step 3);
3) arrange one stabilization time constant T
c, T here
c=cT
d, c > 0 and ≠ 1, continues the remote signalling in detecting step 1), until current time is t
3=t
1+ T
c+ T
d;
4) at t
3time, state value reverts to v

3in time, state value does not revert to v
0, send item: remote signalling time t
3state is v
1, return step 1).
Described Key dithering time constant T

cunit be millisecond or microsecond.
Coefficient C=2 in described step 3).
Ben Fa meter adopts said method to process telesignalling dithering problem, arranging a Key dithering time reduces remote signalling undesired signal, arrange an in stable condition time reduce repeat transmission state displacement, remote signalling displacement event is not generated within the removal shaking interference time, just remote signalling change events is generated within the in stable condition time, removal shaky time and in stable condition time correlation connection, the undesired signal with different frequency can be processed respectively, this method energy fast processing remote signalling displacement, reduces remote signalling displacement wrong report simultaneously and fails to report information.

Embodiment
Illustrate below in conjunction with accompanying drawing and be described in further detail embodiments of the invention, but the present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar change thereof, all should list protection scope of the present invention in.
Shown in Fig. 1, electric system remote signalling displacement de-jittering method provided by the present invention, realization flow is as follows:
1) detect remote signalling state change information, if remote signalling state sends change, then record remote signals transformation period t
1, remote signalling state value v before change
0, after change, remote signalling state value is v
1;
2) a Key dithering time constant T is set
dif remote signalling is at t
2in time, t here
2=t
1+ T
d, remote signalling state value reverts to v
0, then think signal disturbing, ignore this telesignalling dithering, this detects end, returns step 1); If remote signalling is at t
2time, state value does not revert to v
0, then think that remote signalling conjugates, and sends item: remote signalling is at t
1time state conjugates; Continue step 3) below;
3) arrange one stabilization time constant T
c, T here
c=cT
d, c > 0 and ≠ 1, continues the remote signalling in detecting step 1), until current time is t
3=t
1+ T
c+ T
d;
4) at t
3time, state value reverts to v
0, send item: remote signalling time t
3involution, returns step 1); If t
3in time, state value does not revert to v
0, send item: remote signalling time t
3state is v
1, return step 1).
Constant T stabilization time arranged in the present invention
cvalue size can adjust according to different remote signalling.
Embodiment illustrated in fig. 2 is by Key dithering time T
dwith T stabilization time
cbetween be set to 2 times of relations, namely
T
c=2T
