Disclosed are a three-dimensional wildfire monitoring and control system and method for a power transmission corridor. The system includes: a wildfire-induced trip risk assessment module, for assessing, when a wildfire is detected in a power transmission corridor, a wildfire-induced trip risk in real time so as to determine whether to issue a wildfire warning; an online wildfire monitoring device layout planning module, for generating an online wildfire monitoring device layout plan for transmission lines based on the wildfire-induced trip risk, a blind spot of satellite monitoring and importance levels of the transmission lines; and a three-dimensional power transmission corridor wildfire monitoring and warning module, adopting multi-source satellites and drones, and realizing three-dimensional wildfire monitoring of the power transmission corridor by monitoring through online wildfire monitoring devices provided according to the layout plan, the multi-source satellites and the drones.

Three-dimensional wildfire monitoring and control method and system for power transmission corridor

A voice processing method includes: determining a historical voice frame corresponding to a target voice frame; acquiring a frequency-domain characteristic of the historical voice frame and a time-domain parameter of the historical voice frame; obtaining a parameter set of the target voice frame according to a correlation between the frequency-domain characteristic of the historical voice frame and the time-domain parameter of the historical voice frame, the parameter set including at least two parameters; and reconstructing the target voice frame according to the parameter set.

This disclosure relates to encoding and decoding methods and apparatuses. The method may include encoding an isignal frame, to obtain an encoded result of the isignal frame. The method may further include performing forward error correction encoding on first n signal frames, to obtain forward error correction encoded results corresponding to the first n signal frames. The first n signal frames may be signal frames located before the isignal frame. The method may further include synthesizing the encoded result of the isignal frame and the forward error correction encoded results corresponding to the first n signal frames, to obtain an iencoded frame corresponding to the isignal frame. The iencoded frame may comprise a flag bit, the flag bit may be for indicating a number n, and n may be a positive integer greater than or equal to 2.
