Abstract

The invention discloses a substation identifier comprising an output interface unit, a data processing unit and a signal processing unit. The output interface unit comprises a three-phase signal output interface and a man-machine interaction interface, the data processing unit is connected with the man-machine interaction interface, the signal processing unit comprises an FPGA (field programmable gate array) digital signal processor and a time slice controller connected with the FPA digital signal processor, the FPGA digital signal processor is connected with the data processing unit, and the time slice controller is respectively connected with the data processing unit and the three-phase signal output interface. The substation identifier is a substation-side device of a transformer area user identifier and transmits carrier signals to a remote terminal by three-phase independent lines by slot time sharing.

Description

technical field [0001] The invention relates to a station identification device, which belongs to the station end equipment of the user identification device in the station area, and is the transmitting end of the carrier signal. Background technique [0002] In the low-voltage power supply line, overhead lines and cable lines are generally used to supply power to residents and residential buildings from the transformer station area. In the actual operation of household access lines, due to urban construction and municipal planning, household access lines are mostly installed in batches and span a long period of time. As a result, the user's electricity consumption information and retained files are chaotic, and there is a discrepancy between the actual load of electricity customers in the transformer station area and the user information in the electricity marketing system. As a result, the assessment of line damage in a single station area and the emergency repair and pow...
