Description
Technical field
The utility model circuit field more particularly to a kind of Dual module operation power concentrator based on more communication modes.
Background technology
Include concentrator in the communication equipment of electric system, is normally located at ammeter or ammeter terminal and electric power main website
Between, it is mainly used to realize the upload of information, assigns.The composition of existing concentrator, such as Chinese patent CN03228204.4 institutes
A kind of disclosed spread spectrum signal carrier data collector, it includes spread spectrum carrier circuit, and spread spectrum carrier circuit is by microcontroller, serial data
Memory, spread spectrum carrier wave integrated circuit, power amplifier, coupler, triode composition, spread carrier circuit and serial ports conversion chip
Output end be connected, the input terminal of serial ports conversion chip is connect with the output end of computer PC104, and computer PC104's is defeated
Enter end connection telephone wire.The transmission of data is carried out using the transmission mode of telephone network and spread spectrum carrier wave, and mutually only using three groups
Vertical carrier module carries out the coupling of signal, with the centralized control to electric network data.
The composition and working principle of existing concentrator, as shown in Figure 1, generally including power supply 1a and being powered by power supply 1a
And the circuit system 2a to work, power supply 1a are responsible for for external alternating current being converted into the power supply needed for circuit system 2a work；Circuit system

The composition of system includes primary processor, downgoing communication unit and uplink communication unit again, which includes at least
Two kinds of communication modules, those modules and the primary processor are communication connections, the primary processor according to preset sequence from
Dynamic selection its own carry out communication connection with one of which communication module and realize the uplink communication of concentrator.
Said program, which is proposed, to be fallen uplink communication unit using reducing concentrator by way of at least two communication modules
The possibility of line, but the communication module of said program is all fixedly connected with primary processor, cannot achieve as needed with
Meaning replaces the purpose of module, replaces module etc. for staff and just brings inconvenience.
