Description
Technical field
The present invention relates to electric and electronic technical field and digital signal encoding field, be specifically related to a kind of Intelligent platform zone and identify
Device and method.
Background technology
At present, electric company is for the confirmation of the load nature of electricity consumed of power consumer and management, how by the electricity consumption of power consumer
Information on request slip, and the change of load nature of electricity consumed and real load nature of electricity consumed for power consumer all lacks effective supervision
And management, and power utility check link also lacks effective detection means to this type of situation.
Existing low-voltage cable and platform district centralized meter-reading system gather resident's electric energy information, then add up the data gathered
Process, it is impossible to realize the load nature of electricity consumed of low-voltage cable with platform district power consumer is analyzed, thus cause electric company to be in
The most passive state；In addition, existing low-voltage electric energy information system is due also to low-voltage cable is many with platform district user, and structure is multiple
Miscellaneous, cause its system when checking, there are human and material resources and put into huge, relatively big to electric power monitoring dependency and be difficult to obtain in advance
The situation of phase effect.
Conventional cable and platform district recognition method are on low-voltage cable, when voltage is about 100V, by cable fire
Line and zero line short circuit, send a heavy current pulse, the equipment on cable, by detecting this current impulse, judge cable
