Line electric energy meter acquisition system.
Background technology
Solve to estimate existing for current China's Field of Electricity Meter Reading System copy, pretermission, mistake are copied and meter reading not in time phenomena such as, by electricity
It is China's power industry great difficult problem urgently to be resolved hurrily that the acquisition of table data is changed into automatic data logging by traditional manual metering.
Automatic meter reading system mainly uses cable communicating technology and power-line carrier communication at present.Cable communicating technology
As conventional method, the stability of system is fine, but line laying project amount is big, and easily by artificial damage, and if residential building is built
Cheng Hou, then in wall surface bracing wire, resident is difficult to receive.Power line carrier meter reading does not obtain on a large scale should at home always yet
With the main reason is that a large amount of harmonic wave interference problems of domestic electrical circuit institute's band in itself are not solved very well, in data
In transmit process, often there is error code, the situation for losing code, data is made large error occur.
With reference to 202434042 U of documents CN, the document discloses a kind of Automatic meter reading system, it includes at least
One electric energy meter, electric energy meter are connected by RS-485 with collector, and collector is communicated by RF modules with concentrator, and concentrator leads to
GPRS/3G is crossed to communicate with main website.Plurality of electric energy meter and collector are wired connections, for some electric energy meter numbers compared with
It is more, irregular occasion is distributed, entity wiring is very complicated, and it may also be desirable to knob-and-tube wiring.
Utility model content
In view of the deficiencies of the prior art, the purpose of this utility model is that one kind need not connect up, equipment installs letter cumbersomely

Collecting system, including system main website and multigroup ammeter component, wherein, every group of ammeter component includes an ammeter control module and extremely
A few multifunctional electric energy meter;The system main website includes processor, for the storage module of store digital information, controls mould
Block, signal convert transceiver module and the power module for powering into modules, wherein, the processor respectively with storage
Module, control module, signal conversion transceiver module phase telecommunications connection;Signal conversion transceiver module respectively with multigroup meter group
The ammeter control module of part is communicated by GPRS wireless networks;The processor is for handling by modules and be preset with
The telecommunications that outer computer is sent is good and electric signal after modules and the outer computer transmission process that is preset with;Institute
Signal conversion transceiver module is stated the electric signal of reception is converted into corresponding GPRS signals and converts the GPRS signals of reception
Into corresponding electric signal transmission to processor;The control module is communicated with the outer computer being preset with, wherein, the control
The switching sent by outer computer electricity instruction is converted into control electric signal rotating speed to processor by molding block;It is electric described in every group
It is communicated between the ammeter control module of table component and multiple function electric energy meters by wireless telecommunications.
Further, communicated between the ammeter control module and multipotency electric energy meter by the infrared communication unit being preset with
Letter, wherein, the infrared communication unit is infrared wireless communication.
Further, the multifunctional electric energy meter is interior power-off electric energy meter.
Further, the GPRS wireless data transmission terminals are DTU.
The advantageous effect of the utility model against existing technologies is that system main website and ammeter component pass through ammeter control module
GPRS wireless networks are carried out with signal conversion transceiver module to communicate;And ammeter control module and multi-functional electricity in ammeter component
Energy table is also wireless communication connection;So system main website energy remote wireless control and the data parameters of acquisition multifunctional electric energy meter,
Complicated cumbersome wiring need not be carried out as traditional electric energy meter acquisition system, meter reading is carried out without artificial, saves
Human resources.
