Phase identification method and identification system of station area based on electric power wireless private network and carrier

Abstract

The invention discloses a station area phase identification method and an identification system based on a power wireless private network and a carrier wave, and relates to a station area identification method. At present, the power line has poor anti-interference, high error rate of two-way data transmission, and low identification success rate. The invention includes steps: on the side of the transformer, configure the station area and phase parameters; the phase transmitter of the station area adopts a high-frequency 100MHz frequency band, and sends a carrier signal to the meter through the carrier module at regular intervals; the main control unit of the meter performs information analysis. After receiving the same station area and phase for many times, it is considered that the station area phase is correctly identified, and the data is sent back to the master station through the communication module. The master station notifies the station area phase transmitter to stop sending the station area phase information, and the master station notifies the master The control unit stops receiving carrier information and disables the carrier module. This technical solution improves the success rate of station area phase identification, ensures the security and timeliness of data transmission, and provides effective data support for the master station to carry out station area phase-related services.

Description

technical field [0001] The invention relates to a station area identification method, in particular to a station area phase identification method based on a power wireless private network and a carrier wave. Background technique [0002] The current mainstream station area phase identification scheme is based on the concentrator and the meter through the two-way communication of the power line carrier to realize the station area phase identification, and then the concentrator transmits the identified data back to the master station through the wireless public network or other remote transmission equipment, such as figure 1 shown. Due to the poor anti-interference ability of the power line, the error rate of two-way data transmission is high, and the success rate of recognition is low; and the concentrator reports to the master station that it cannot realize the closed-off detection of the station area, and the correctness of the data returned to the master station cannot be ...
