The utility model content
The purpose of this utility model provides a kind of power line broadband network kilowatt meter reading-out system, based on power line network, utilizes the OFDM modulation means of PLC technology to realize making a copy of, transmit and exchanging of data.
Above-mentioned purpose is realized by following technical scheme:
A kind of power line broadband network kilowatt meter reading-out system comprises: electric energy meter, collector, collection terminal bridge, power line, receiving terminal bridge, switch, concentrator, router, local side main website; Collector one end is connected with electric energy meter, and the other end is connected with the collection terminal bridge, collection terminal bridge and then be connected with power line; Receiving terminal bridge one end is connected with power line, and the other end is connected with switch, switch and then be connected with concentrator; Concentrator can be connected with the local side main website communicatedly by router.
The power line broadband network kilowatt meter reading-out system that the utility model provides can carry out remote data transmission by power line with the voltmeter signal that collects, based on the existing power spider lines, reduced the cost and the difficulty of construction of construction, and data can be transmitted the area that the arrival power line can arrive.
Description of drawings
Fig. 1 is a power line broadband network kilowatt meter reading-out system connection diagram.
Embodiment
As shown in Figure 1, electric energy meter is installed on user side, is used to measure each user's power consumption, the output variable.Adopt " mode hand in hand " that a plurality of electric energy meter series connection back is connected with collector by 485 multiple twin shielding conductors, after collector carries out data acquisition by 485 interfaces to a plurality of electric energy meters, convert the Transmission Control Protocol signal to, the collection terminal bridge is modulated to the PLC signal with the Transmission Control Protocol signal by OFDM, and amplifies, is coupled on the power line.
Continuation is referring to Fig. 1, receiving terminal bridge one end is connected with power line, other end network interface is connected with switch, is transferred to switch by grid line after the PLC signal on the power line is converted into the TCP signal, and switch transfers to concentrator with TCP signal in the grid line.Concentrator is used for a distribution zone energy information is gathered, handles, stored and controls, and carries out exchanges data by the main website in route and the local side afterwards.Master station application software is based on the Windows operating system platform more than the Windows2000 version, and database is installed.The function of main website comprises: (1) management concentrator, collector and ammeter; Specifically comprise: the interpolation of a. concentrator, deletion, inquiry, modification parameter wherein; B. the interpolation of collector, deletion, inquiry; C. the editor of ammeter, delete, enable management, Long-distance Control, make a copy of and make a copy of and freeze by the day/moon etc. in real time; (2) provide the data message check, and can monitor communication link; Functions such as (3) storage of data, analysis, report printing output.
A bridge can be with 20 collectors in theory, and collector can be with 128 of electric energy meters of the same type, but the bridge of zones of different must be divided working group separately, can guarantee that just now communication is correct.Determine quantity and the position that terminal is installed according to the amount in every building, and corresponding IP address is set.Collector uses the electric energy meter data of jumbo nonvolatile semiconductor memory member FLASH stored parameter and appointment, and can carry out field network debugging and network parameter setting easily.
Above-mentioned power line broadband network kilowatt meter reading-out system has mainly adopted the PLC technology in collector after, can utilize the existing power spider lines fully, not only reduce wiring, make that the construction change is simple, also save operating expenses but also be broadband network.It is simple, quick to implement the construction of power line broadband network kilowatt meter reading-out system, and the general operating expenses of automatic data logging accounts for 20% of product expense, and power line broadband network kilowatt meter reading-out system operating expenses accounts for 5% of product expense, and construction cost has just saved 15%.Check meter and solved also simultaneously that bandwidth is narrow, speed is slow excessively, real-time is poor, the not high factor of stability in described broadband.
