Description
Technical field
The present invention relates to power carrier meter register method technical fields, in particular to one kind being used for the adaptive overloading of power consumer
The method of wave modulation system meter reading.
Background technology
With gradually application of the Automatic meter reading system in power industry, apply automatic data logging field scheme increasingly
It is more, but from the point of view of the statistical data of the equipment of practical hanging net operation, the success rate of automatic data logging is not very high, main limitation
Property is the high-speed and reliability of carrier channel.Carrier technology is main used by Automatic meter reading system relatively common at present
For：FSK, BPSK technology used by domestic Automatic meter reading system, in the world Prime, G3 skill used by Automatic meter reading system
Art, but carrier channel used by current Automatic meter reading system is single, once the interference signal of power grid is excessive, then can not
Realize meter-reading function, poor, the low success rate of defect of meter reading that there are interference free performances.
Invention content
The technical problem to be solved by the present invention is to different modulating can adaptively be switched to according to power grid environment by providing one kind
Pattern and frequency range, to reach channel optimisation, to come improve meter reading success rate be used for power consumer adaptive multi-carrier tune
The method of mode meter reading processed.
It is copied for power consumer adaptive multi-carrier modulation system in order to solve the above technical problems, the present invention provides one kind
The method of table, includes the following steps：
A, after the power is turned on, ammeter data acquisition module is with the modulating mode given tacit consent to and the frequency range of acquiescence for ammeter data acquisition module
Work；
B, ammeter data acquisition module is at a certain time interval detected the signal strength of itself, such as detects letter
Number be less than a threshold values, then enter step c, otherwise with current modulating mode and band operation, and carry out meter reading；
C, ammeter data acquisition module judges whether working frequency range has been switched to last under current modulating mode
It is a, if working frequency range has been switched to the last one, then step d is entered, otherwise, ammeter data acquisition module cuts working frequency range
Shift to return to step b after next working frequency range in current modulating mode；
D, ammeter data acquisition module judges whether modulating mode has been switched to the last one, as modulating mode has been switched to
The last one, then enter step e, and otherwise, ammeter data acquisition module is switched in next modulating mode, and with next
Then the band operation given tacit consent in modulating mode returns again to step b；
E, modulating mode and frequency range are switched to the modulating mode of acquiescence and the frequency of acquiescence by ammeter data acquisition module respectively
Return to step b after section.
After the above method, compared with prior art, the present invention has the following advantages：Ammeter data acquisition module can
Different modulating pattern and frequency range are adaptively switched to according to power grid environment, i.e., when ammeter data acquisition module can not collect power grid
When the data of middle ammeter (interference signal of some frequency range is excessive in power grid), ammeter data acquisition module can be in preset modulation
It is switched between pattern and frequency range, the best modulating mode of final choice and frequency range carry out meter reading, improve ammeter data
The anti-interference and reliability of acquisition module, improve the success rate of Automatic meter reading system meter reading.
Specific implementation mode
Below by specific implementation mode, the present invention is described in further detail.
In this embodiment, the method for power consumer adaptive multi-carrier modulation system meter reading of the invention,
Include the following steps：
A, after the power is turned on, ammeter data acquisition module is with the modulating mode given tacit consent to and the frequency range of acquiescence for ammeter data acquisition module
Work；
B, ammeter data acquisition module is at a certain time interval detected the signal strength of itself, such as detects letter
Number be less than a threshold values, then enter step c, otherwise with current modulating mode and band operation, and carry out meter reading；
C, ammeter data acquisition module judges whether working frequency range has been switched to last under current modulating mode
It is a, if working frequency range has been switched to the last one, then step d is entered, otherwise, ammeter data acquisition module cuts working frequency range
Shift to return to step b after next working frequency range in current modulating mode；
D, ammeter data acquisition module judges whether modulating mode has been switched to the last one, as modulating mode has been switched to
The last one, then enter step e, and otherwise, ammeter data acquisition module is switched in next modulating mode, and with next
Then the band operation given tacit consent in modulating mode returns again to step b；
E, modulating mode and frequency range are switched to the modulating mode of acquiescence and the frequency of acquiescence by ammeter data acquisition module respectively
Return to step b after section.
Such as：The modulating mode that ammeter data acquisition module powers on acquiescence is OFDM modulating modes, the working frequency range of acquiescence
For 5~95KHz, ammeter data acquisition module is at a certain time interval detected the signal strength of itself, such as ammeter number
Detect that the interference signal of the frequency range of 5~95KHz is too strong according to acquisition module, frequency range is switched to 200 by ammeter data acquisition module
~400KHz, if ammeter data acquisition module detects that the interference signal of the frequency range of 200~400KHz is still too strong, ammeter data
Modulating mode is switched to S-FSK modulating modes by acquisition module, and frequency range switches to 5~95KHz, as ammeter data acquisition module is examined
Measure channel quality after switch modulation pattern and frequency range preferably (interference signal is few), ammeter data acquisition module is then with current
Modulating mode and band operation, and realize meter reading.
Above embodiment be only the preferred embodiment of the present invention is described, not to the scope of the present invention into
Row limits, and under the premise of not departing from design spirit of the present invention, those of ordinary skill in the art make technical scheme of the present invention
The various modifications gone out and improvement should all be fallen into the protection domain of claims of the present invention determination.
