Technical field
The present invention relates to electrical facility technical field, in particular to a kind of power user power consumption information acquisition system and its adopt
Set method.
Background technology
Currently, power user power consumption information acquisition system mainly include acquisition terminal (5), several ammeters (6) and with electricity
Several identical indoor display units (7) of table (6) quantity, specific connection structure is as shown in Figure 1, the acquisition terminal
(5), acquisition terminal communication module (51), ammeter communication module are respectively arranged with inside ammeter (6) and indoor display unit (7)
(61) and indoor display unit communication module (71), several described ammeters (6) pass through the first power line (8) and acquisition terminal
(5) it is connected, several described indoor display units (7) pass through independent second power line (9) and several ammeters (6) one respectively
One is correspondingly connected with, and acquisition terminal (5) and connect ammeter (6) network consisting, ammeter (6) are managed collectively by acquisition terminal (5), indoor
Display unit (7) does not access network then, and indoor display unit (7) connect with ammeter (6) for P2P, and acquisition terminal (5) and ammeter
(6) it is attached using power line carrier communication mode between, between ammeter (6) and indoor display unit (7), modulation system is
FSK modulation；Since indoor display unit (7) does not access network, hold between not corresponding indoor display unit (7) and ammeter (6)
Easily there is the problem of communication crosstalk, i.e., indoor display unit (7) is easy display and the not corresponding ammeter of interior display unit (7)
(6) power information, to cause display mistake, and due to the carrier modulation side of above-mentioned power user power consumption information acquisition system
Formula is FSK modulation, and it is big that there are occupied bandwidths, the slow disadvantage of communication speed.
Invention content
The technical problem to be solved by the present invention is to, provide one kind can avoid indoor display unit and not corresponding ammeter it
Between occur communication crosstalk phenomenon power user power consumption information acquisition system and its acquisition method.
In order to solve the above technical problems, the present invention provides a kind of power user power consumption information acquisition system, including acquisition
Terminal, several ammeters and several indoor display units identical with ammeter quantity, the acquisition terminal, ammeter and interior are aobvious
Show and is respectively arranged with acquisition terminal communication module, ammeter communication module and indoor display unit communication module, ammeter inside unit
It is connected with acquisition terminal by the power line for establishing same communication network with indoor display unit.
The acquisition method of the power user power consumption information acquisition system of the present invention, includes the following steps：
A, system initialization, communication modulation mode are OFDM modulation systems, each ammeter and each indoor display unit to acquisition
Terminal request is registered, and each ammeter and each indoor respective mailing address of display unit active upload are to acquisition terminal, indoor display
The indoor display unit mailing address that unit uploads possesses the address mark position for being different from ammeter mailing address so that acquisition terminal
Ammeter mailing address and indoor display unit mailing address can be distinguished, acquisition terminal establishes ammeter mailing address after succeeding in registration
Archives and indoor display unit mailing address archives, and ammeter mailing address is saved in ammeter mailing address archives, by room
Interior display unit mailing address is saved in indoor display unit mailing address archives, meanwhile, acquisition terminal is by the pairing of ammeter
Flag bit is saved in ammeter mailing address archives；
B, the pairing flag bit of the ammeter in acquisition terminal inquiry ammeter mailing address archives, acquisition terminal is periodically to each room
Interior display unit issues the ammeter mailing address of unpaired ammeter；
C, indoor display unit obtains the ammeter mailing address of unpaired ammeter in network from acquisition terminal, and is shown to room
On interior display unit；
D, user selects the ammeter mailing address to be matched, indoor display unit logical to the ammeter from indoor display unit
Believe that the corresponding ammeter in address sends pairing request, which inquires the pairing flag bit of oneself, if the ammeter inquires oneself not
It is matched with other indoor display units, then by pairing request, and the indoor display unit for preserving the interior display unit is logical
Believe address, and be to have matched by pairing mark position, is matched with other indoor display units if the ammeter inquires oneself,
Then refuse pairing request；
E, indoor display unit with after ammeter successful matching, the interior display unit to interior display unit pairing
Ammeter ask electricity consumption data, ammeter to return to electricity consumption data to the interior display unit, display unit realization in the interior is to ammeter
The display of power information.
The indoor display unit mailing address that the indoor display unit mentioned in step a uploads, which possesses, is different from ammeter communication
The address mark position of address, by the setting of address mark position, acquisition terminal can judge that the data received are to come from ammeter
Or from indoor display unit, if the data received are to carry out frame decoding processing from ammeter, if receiving
Data are then abandoned and are not dealt with from indoor display unit.
After above-mentioned acquisition system and acquisition method, compared with prior art, the present invention has the following advantages：The present invention
Indoor display unit network is accessed into, all ammeters and indoor display unit are managed collectively by acquisition terminal, each indoor aobvious
Show that unit obtains the mailing address of unpaired ammeter from acquisition terminal, and can realize and be matched with corresponding ammeter, is unworthy of
To indoor display unit and ammeter between be not in communication crosstalk the problem of, it is existing to avoid indoor display unit display mistake
The generation of elephant；By using the modulation system of OFDM, the bandwidth of power grid is dramatically saved, traffic rate is improved.
