Description
Technical field
The present invention relates to intelligent grid technical field, especially relate to a kind of power line carrier meter register method and system.
Background technology
In power line carrier meter reading system, collector be a kind of control device ，Qi position for electric system between ammeter and concentrator, that is: ammeter--collector--concentrator.
Collector mainly contains three functions: gather ammeter data (Ru Feng, paddy, the data of flat different periods), preserve, by power carrier, responded the order uploading data of concentrator or passed down fill order (as ammeter has the function that can cut off user power utilization) to ammeter.
At present, residential building is all generally that the ammeter of concentrating ammeter that ，Ji Ge family is installed is all neatly installed concentratedly together abreast.Situation for this concentrated dress table, just can apply the data that collector carrys out every ammeter of centralized collection, a common collector is installed nearby, manage 12,32 or 64 ammeters (can select according to the quantity of ammeter the collector of different model), then by power carrier the data upload of these ammeters to concentrator.And concentrator is contained near transformer conventionally, as switchgear building.
Existing collector and lower extension ammeter work in master slave mode, macroscopic view, within the different time, in these two pairs of communication facilitiess of concentrator and collector and collector and lower extension ammeter, only have a pair of communicating, cannot process concurrently concentrator and be handed down to the transmitting order to lower levels that numerous collectors or collector are handed down to numerous ammeters, concentrator need to take much time and wait for the response of collector, and collector also will take much time and waits for the response message of each lower extension ammeter, so just cause the work efficiency of whole centralized meter-reading system low, centralized meter-reading system functional reliability is lower, be unfavorable for the benign development of centralized meter-reading system.
Summary of the invention
