description | The invention provides an intelligent acquisition and remote transmission system for power grid fault recording data. The intelligent acquisition and remote transmission system comprises a plurality of fault recording data acquisition devices and a receiving and analyzing device which are connected with one another through a data communication network, each fault recording data acquisition deviceis connected with a preset external voltage source or preset external equipment to acquire internal working direct-current voltage; during normal operation, the Baud rate of an external relay protection device is preset in a self-adaptive mode, and fault recording data are collected as binary data, processed into data of a unified format and then forwarded to the receiving and analyzing device; and the receiving and analyzing device receives the data sent by each fault recording data acquisition device, processes the data into hexadecimal data, further restores the fault recording data, formsa recording graph or a dat |
