Abstract
A disclosed electric-power-user self-adaptive multicarrier modulation mode meter-reading method comprises the following steps: a, an ammeter data acquisition module works in a default modulation mode and a default frequency range; b, the ammeter data acquisition module detects self signal intensity at certain time interval; c, under a current modulation mode, the ammeter data acquisition module determines whether the work frequency range is switched to the last one; d, the ammeter data acquisition module determines whether the modulation mode is switched to the last one; and e, the ammeter data acquisition module respectively switches the modulation mode and the frequency range to the default modulation mode and the default frequency range and then returns to the step b. According to the method, the channel is optimized by self-adaptively switching into different modulation modes and frequency ranges according to the electrical network environment, and thus the meter reading success rate is improved.
Description
Technical field
The present invention relates to power carrier meter register method technical field, specifically refer to a kind of method of checking meter for power consumer adaptive multi-carrier modulation system.
Background technology
Along with the progressively application of Automatic meter reading system in power industry, the scheme being applied in automatic data logging field gets more and more, but the statistics of the equipment from actual hanging net operation, the success ratio of automatic data logging is not two-forty and reliability that very high, main limitation is carrier channel.The ZAP that more common Automatic meter reading system adopts at present is mainly: FSK, BPSK technology that domestic Automatic meter reading system adopts, Prime, G3 technology of adopting of Automatic meter reading system in the world, but the carrier channel that current Automatic meter reading system adopts is single, once the undesired signal of electrical network is too much, then cannot realize meter-reading function, there is interference free performance difference, defect that success ratio of checking meter is low.
Summary of the invention
The technical problem to be solved in the present invention is, there is provided one can switch to different modulating pattern and frequency range according to power grid environment self-adaptation, to reach channel optimisation, thus improve the method for checking meter for power consumer adaptive multi-carrier modulation system of success ratio of checking meter.
For solving the problems of the technologies described above, the invention provides a kind of method of checking meter for power consumer adaptive multi-carrier modulation system, comprising the following steps:
After a, ammeter data acquisition module power on, ammeter data acquisition module is with the modulating mode of acquiescence and the band operation of acquiescence;
B, ammeter data acquisition module detect the signal intensity of self at a certain time interval, as very weak or lower than a threshold values in signal detected, then enter into step c, otherwise with current modulating mode and band operation, and check meter;
C, ammeter data acquisition module are under current modulating mode, judge whether working frequency range is switched to last, as working frequency range is switched to last, then enter into steps d, otherwise ammeter data acquisition module returns step b after working frequency range being switched to the next working frequency range in current modulating mode;
D, ammeter data acquisition module judge whether modulating mode is switched to last, as modulating mode is switched to last, then enter into step e, otherwise, ammeter data acquisition module is switched in next modulating mode, and with the band operation given tacit consent in next modulating mode, and then return step b;
E, ammeter data acquisition module return step b after modulating mode and frequency range are switched to the modulating mode of acquiescence and the frequency range of acquiescence respectively.
After adopting said method, compared with prior art, the present invention has the following advantages: ammeter data acquisition module can switch to different modulating pattern and frequency range according to power grid environment self-adaptation, namely when ammeter data acquisition module cannot collect the data of ammeter in electrical network (in electrical network, the undesired signal of certain frequency range is too much), ammeter data acquisition module can switch between the modulating mode preset and frequency range, final best modulating mode and the frequency range selected is checked meter, improve anti-interference and the reliability of ammeter data acquisition module, improve the success ratio that Automatic meter reading system is checked meter.
Embodiment
Below by embodiment, the present invention is described in further detail.
In this specific embodiment, method of checking meter for power consumer adaptive multi-carrier modulation system of the present invention, comprises the following steps:
After a, ammeter data acquisition module power on, ammeter data acquisition module is with the modulating mode of acquiescence and the band operation of acquiescence;
B, ammeter data acquisition module detect the signal intensity of self at a certain time interval, as very weak or lower than a threshold values in signal detected, then enter into step c, otherwise with current modulating mode and band operation, and check meter;
C, ammeter data acquisition module are under current modulating mode, judge whether working frequency range is switched to last, as working frequency range is switched to last, then enter into steps d, otherwise ammeter data acquisition module returns step b after working frequency range being switched to the next working frequency range in current modulating mode;
D, ammeter data acquisition module judge whether modulating mode is switched to last, as modulating mode is switched to last, then enter into step e, otherwise, ammeter data acquisition module is switched in next modulating mode, and with the band operation given tacit consent in next modulating mode, and then return step b;
E, ammeter data acquisition module return step b after modulating mode and frequency range are switched to the modulating mode of acquiescence and the frequency range of acquiescence respectively.
Such as: ammeter data acquisition module power on acquiescence modulating mode be OFDM modulation pattern, the working frequency range of acquiescence is 5 ~ 95KHz, ammeter data acquisition module detects the signal intensity of self at a certain time interval, as ammeter data acquisition module detects that the undesired signal of the frequency range of 5 ~ 95KHz is too strong, frequency range is switched to 200 ~ 400KHz by ammeter data acquisition module, as ammeter data acquisition module detects that the undesired signal of the frequency range of 200 ~ 400KHz is still too strong, modulating mode is switched to S-FSK modulating mode by ammeter data acquisition module, frequency range switches to 5 ~ 95KHz, as ammeter data acquisition module detects the channel quality better (undesired signal is few) after switch modulation pattern and frequency range, ammeter data acquisition module is then with current modulating mode and band operation, and realize checking meter.
Above embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
