Description
Technical field
The present invention relates to intelligent power grid technology field, especially relate to a kind of power line carrier meter register method and system.
Background technology
In power line carrier meter reading system, harvester be a kind of for the control device in power system, at its position
Between ammeter and concentrator, that is,：Ammeter -- harvester -- concentrator.
Harvester mainly has three functions：Gather ammeter data (Ru Feng, paddy, the data of flat different periods), preserve, pass through
The order that power carrier responds concentrator uploads data or passes under ammeter and execute order and (can cut off user power utilization as ammeter has
Function).
At present, residential building is typically all to concentrate ammeter to install, and that is, the ammeter at each family is all neatly abreast installed concentratedly one
Rise.For this situation concentrating dress table so that it may application harvester comes the data of every piece of ammeter of centralized collection, a usual collection
Device is installed nearby, 12 pieces of management, 32 pieces or 64 pieces of ammeters (can select the harvester of different model according to the quantity of ammeter), so
Afterwards concentrator is uploaded to the data of these ammeters by power carrier.And concentrator is commonly mounted near transformator, such as distribution
Room.
Existing harvester works in master slave mode with lower extension ammeter, from macroscopic view, within the different time, concentrates
Device is only being communicated for a pair with lower extension ammeter these two pair communication equipment with harvester and harvester, that is, cannot be concurrently
Process concentrator and be handed down to numerous harvesters or harvester is handed down to the transmitting order to lower levels of numerous ammeters, concentrator needs to spend substantial amounts of
Time waits the response of harvester, and harvester also will take much time and wait the response message of each lower extension ammeter, so
The work efficiency resulting in whole centralized meter-reading system is low, and centralized meter-reading system functional reliability is relatively low, is unfavorable for the optimum of centralized meter-reading system
Development.
Content of the invention
