Abstract
The utility model provides a power line high-speed broadband carrier wave meter-reading system. The power line high-speed broadband carrier wave meter-reading system is characterized by comprising a master station system, a plurality of concentrators, a plurality of collectors and a plurality of ammeters, wherein the number of concentrators, the collectors and the ammeters are the same, the master station system is connected with signals of the plurality of the concentrators through a power line private network or a wireless public network, the plurality of the concentrators and the plurality of the collectors are in one-to-one correspondence connection through a power line broadband carrier wave module and/or a RS-485 data bus, and each collector is connected with at least one ammeter signal. The power line high-speed broadband carrier wave meter-reading system breaks through performance limitations of being poor in capacity of resisting disturbance and low in transmission rate in a present narrow-band power line carrier wave concentrator. Performance of a meter-reading concentrator is improved. Therefore, the power line high-speed broadband carrier wave meter-reading system can be applied in more severe environment and capable of collecting information which is not obtained in time in a traditional narrow-band carrier wave mode.
Description
Technical field
The utility model relates to for electrical domain, is specifically related to a kind of line of electric force high-speed wideband carrier meter reading system.
Background technology
Along with the development of society and the transition in epoch, Automatic meter reading system arises at the historic moment.And at present, the carrier communication mode between domestic concentrator and collector can be divided into amplitude shift keying (ASK), frequency shift keying (FSK) or phase-shift keying (PSK) (PSK) technology etc.; We are referred to as the narrowband carrier mode these transmission modes.These technical schemes all adopt the single carrier mode to transmit, and communication channel is built up in certain frequency of 80～500kHZ, for example 270kHz or 120kHz, and communication channel is single, and transfer rate all is not more than 500bps.The transmission occasion that this single carrier wave channel and low traffic rate can't satisfy big data quantity.
The utility model content
In view of this, be necessary the problem mentioned for background technology, a kind of automatic meter reading system with broadband power line carrier communication function at a high speed is provided.This kilowatt meter reading-out system adopts the modulation system of orthogonal frequency division multiplexi (OFDM), communication channel is distributed in 1536 frequencies between the 2M-32MHz, many and the support multiplex technique of carrier channel, depend on this advanced modulation system, the transfer rate of whole system can up to 200Mbps, surmount far away in traditional narrowband carrier mode.
The technical solution of the utility model is specific as follows:
A kind of line of electric force high-speed wideband carrier meter reading system, it comprise main station system, a plurality of concentrator, with the same number of a plurality of collectors of described a plurality of concentrators and a plurality of ammeter, described main station system is connected with a plurality of concentrator signals by line of electric force private network or wireless public network, described a plurality of concentrator and described a plurality of collector connect one to one by power wire broadband carrier module and/or RS-485 data bus, and described each collector is connected with at least one ammeter signal respectively.
Be provided with storage chip in the described collector, described storage chip is connected with described concentrator.
Described each collector is connected by 485 multiple twin mask buss with at least one ammeter.
Compared with prior art, the utility model possesses following advantage:
The beneficial effects of the utility model are to have broken through present arrowband power line carrier concentrator poor anti jamming capability, functional limitation that transfer rate is low; The performance of meter-copy collector is got a promotion, thereby can in more rugged surroundings, be used, and can collect the information that the traditional narrow carrier system can't in time obtain.

Fig. 1 is the utility model modular structure synoptic diagram.
Embodiment
As shown in Figure 1, the line of electric force high-speed wideband carrier meter reading system of present embodiment, it comprise main station system, a plurality of concentrator, with the same number of a plurality of collectors of described a plurality of concentrators and a plurality of ammeter, described main station system is connected with a plurality of concentrator signals by line of electric force private network or wireless public network, described a plurality of concentrator and described a plurality of collector connect one to one by power wire broadband carrier module and/or RS-485 data bus, and described each collector is connected with at least one ammeter signal respectively.
Specifically describe as follows:
1, main website management and marketing system can be carried out by the concentrator of line of electric force private network or wireless public network and various places the interactive communication between data, concentrator forms the identifiable only sign of main website according to self data address and IP address, main website management and marketing system can be distinguished each concentrator of different regions by this sign;
2, collector links to each other by 485 multiple twin mask buss with ammeter, and user side is installed ammeter, is used for each user's of metering electric energy loss, output metering numerical value; Collector then returns to exist the storage chip the inside with this metering numerical value collection, waits for making a copy of of concentrator;
3, the communication mode between described concentrator and collector is comprehensive, and is optional, can according to different operating positions and environment for use take above-mentioned a kind of or two kinds as communication mode:
A, between a plurality of concentrators and the collector, can be by existing line of electric force transmission broadband carrier signal, realize interconnecting between concentrator and collector, this kind transmission mode has does not need again to set up network, as long as on-the-spot already installed line of electric force is arranged, just can carry out the data transmission, reduced greatly construction, Master Cost when reducing wiring;
B, between concentrator and collector, if because the load in the line of electric force is not often communicated by letter, weak effect, and the distance between concentrator and collector is closer, we can take the connected mode of RS-485 bus to carry out data transmission, and couple together maintenance 485 interfaces of maintenance 485 interfaces of concentrator and collector and get final product this moment by 485 data lines.This kind mode, stability is high, and communication efficiency is very good, but needs other drawing to establish 485 data lines, and is therefore cumbersome.
