Abstract: The present disclosure provides a multi-source signal synchronization system and method applied to a plurality of signal sources with different collection clock frequencies. The system includes: a timing beacon sending unit, configured to generate RTC timing beacons at a fixed time interval T, and send the RTC timing beacons to slave machine signal sources; a timing beacon receiving unit, configured to be enabled at a moment (T-t1) after receiving a previous RTC timing beacon so as to be in a state for waiting to receive a next RTC timing beacon, and disabled after receiving the next RTC timing beacon; a multi-signal collecting unit, configured to collect a plurality of collected signals; and, a signal synchronization processing unit, configured to align signal headers based on a same synchronization mark of the multiple signals.

Abstract: Disclosed are a method and apparatus for compressing a topology recognition model, an electronic device, and a medium. The method includes: pruning a to-be-compressed model to obtain a pruned model, and training the pruned model to obtain a trained pruned model; quantifying a bit quantity of a weight parameter of each neural network layer in the trained pruned model from a first bit quantity to a second bit quantity to obtain a highly-quantified pruned model, and training the highly-quantified pruned model to obtain a trained highly-quantified pruned model; using the trained highly-quantified pruned model as the to-be-compressed model, continuously pruning and quantifying the to-be-compressed model until a compressed topology recognition model is obtained, and deploying the compressed topology recognition model on an Internet of Things in Power Systems (IOTIPS) terminal, to reduce a size of the topology recognition model while ensuring the topology recognition model meets an accuracy requirement.
