Description of drawings
Fig. 1 is the annexation schematic diagram of the utility model embodiment.
Embodiment
As shown in Figure 1, the line of electric force high-speed narrow-band automatic meter reading system of the present embodiment comprises a main website, the concentrator that at least one is connected with described main website signal, at least one collector that is connected with each described concentrator signal, be provided with concentrator high-speed narrow-band module in the described concentrator, be provided with collector high-speed narrow-band module in the described collector, each collector is connected with at least one ammeter signal.
Described central station is computing machine or server, adopts the information such as Ethernet or GPRS to connect between itself and the concentrator.Described concentrator and described collector adopt the carrier communication of line of electric force high-speed narrow-band.Adopt 485 buses direct-connected between described collector and the described ammeter.
Described main website is installed in power supply administration, the order of checking meter that is issued by main website is dealt into concentrator to data by GPRS or network, send to collector high-speed narrow-band module by concentrator by concentrator high-speed narrow-band module again, pass to again collector, again by collector by 485 data of removing to copy ammeter, copy and turn back to main website by former road again afterwards.
Each concentrator can be managed at most 1200 collectors, and each collector can be managed at most 64 ammeters.
Line of electric force high-speed narrow-band automatic meter reading system major function comprises: basic data management, checks meter and control, query statistic, concentrator setting, system management, and specific as follows: 1, basic data management information: the management of cell information, transformer information, concentrator information, collector information, ammeter information, user profile; 2, check meter and control: mainly comprise check meter by hand, the modules such as automatic data logging, souvenir monitoring, control system of switching on or off electricity; 3, query statistic: archive information inquiry, meter reading data inquiry, the fault inquiry of checking meter, user's electric weight statistics, residential quarter line loss analyzing etc., but Query Result generated query form.4, concentrator setting: segment management when mainly comprising the setting of concentrator password, the management of concentrator table number, concentrator action, concentrator systematic parameter, the check and correction of concentrator clock, concentrator.Automatic meter reading system has been saved the material of field wiring and cost has been installed after having adopted the line of electric force high-speed narrow-band communication technology, it is simple that site operation also becomes, only have the place that line of electric force arrives just can the transmission of data, and the communication distance of line of electric force high-speed narrow-band is far away, can reduce communication facilities, save the cost of equipment.After installing, the debugging in later stage is also fairly simple, and one-step installation transfers passband higher.
Compared to prior art, the system of the present embodiment has the following advantages:
1, antijamming capability is strong, and communication is stable, reliable: present traditional ZAP all is to use single-frequency point, simple modulation technology (BFSK or BPSK), the impact that easily is disturbed; And OFDM adopts hundreds of extremely thousands of sub-carrier-wave transmission data, even individual subcarriers is interfered, by strong coding techniques, data still can be correctly received;
2, carrier channel is had adaptive ability: carrier channel changes fast and unpredictable, and OFDM adopts hundreds of extremely thousands of sub-carrier-wave transmission data, and has the more modulation pattern, can dynamically adjust according to the variation of channel;
3, message transmission rate is high: this point is very important for the promptness and the efficiency numbers that improve the power information collection.The traffic rate of present traditional ZAP is all very low, only has hundreds of bps, and is that the utility model adopts and representative communication speed high-speed narrow-band OFDM technology reaches more than the 100kbps.
The utility model also has following characteristics:
1, power frequency zero crossing transmission: further improve antijamming capability.Simultaneously, the zero passage transmission technology can effectively be avoided the earth leakage protective device mistrip;
2, two-way communication, realize that ammeter is initiatively registered, ammeter archives automatic comparison, active report of event: traditional ZAP mainly adopts " concentrator order " to reach " ammeter is replied " mode and communicates by letter, and concentrator according to the ammeter archives first needs set up routing table.Ammeter is initiating communication initiatively, must wait for the concentrator poll.Can realize the ammeter active communication based on the CSMA/CA of OFDM technology mechanism (carrier sense and collision prevention) and based on the dynamic routing technology of blind relaying, thereby support ammeter initiatively to register active report of event.Initiatively the ammeter of registration can be automatically and the ammeter archives compare, in time find mistake, be convenient to system maintenance.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
