Pure internet access-prepositioned data acquisition method

The invention discloses a pure internet access-prepositioned data acquisition method. The method comprises the following steps that: information collected by a remote wireless fault indicator can be obtained safely through a power distribution automation master station; the remote wireless fault indicator detects telesignalling deflection and telemetry information in a line, and wirelessly uploads the collected information to a pure internet access-prepositioned server through pure internet access; and the pure internet access-prepositioned server receives and processes pure internet access data, and transmits the processed pure internet access data to a security area A of a power distribution automation platform through a reverse physical isolation device in a text file format and parses a file such that real-time data can be formed, and therefore, a requirement for real-time performance when the data pass through the reverse physical isolation device can be satisfied, and a 10kV overhead line can be monitored at the security area A. With the pure internet access-prepositioned data acquisition method provided by the invention adopted, blind dispatch of the 10kV overhead line performed by a dispatcher can be avoided; construction and maintenance cost can be decreased with the reliability of power supply of users ensured; and real-time acquisition and monitoring of fault information distribution and telemetry information of overhead distribution lines can be realized.
