The method belongs to the technical field of panoramic monitoring of ultra-high voltage converter station, and aims to solve the problem that panoramic monitoring image data is directly uploaded to the cloud, occupying a large amount of cloud resources. By adopting multi-scale convolution blocks in the deep multi-scale residual network model to construct low-order and high-order features of images of various scales, the incomplete phenomenon of image detail extraction is avoided, and the residual learning mechanism is adopted to retain low-order rough features, thereby improving the reconstruction ability of the image. Topology optimization constructs the topology structure of the heterogeneous network, and the framework combining deep reinforcement learning and Monte Carlo tree search is used to construct the network according to the pre-defined topology rules. The search result of the Monte Carlo tree strengthens the learning of the deep convolutional neural network, so as to obtain more accurate prediction in the next iteration. After the data is processed in the edge side, it is transmitted to the cloud storage, saving the cloud storage space and transmission bandwidth.

This application relates to the field of network voice acquisition technology, and discloses a high-performance RTP voice acceleration acquisition method and system based on FPGA implementation. The method includes receiving raw IP packets and parsing them to obtain a set of key packet information containing five-tuple information, service type identifiers, and policy matching results; filtering out matching RTP voice packets and extracting the five-tuple information; and accessing the flow table in the first DDR4 memory through a multi-BANK interleaved parallel read / write engine to complete the query. When a flow table entry is empty, a table is created for the five-tuple flow, and a storage token corresponding to the second DDR4 storage address is requested. When a flow table entry matches, the timestamp is updated and the storage address is determined. Then, the RTP payload is extracted, written to the corresponding space, and counted. When the count reaches a threshold, an RTP voice compression frame is assembled and output. If the flow duration times out, the storage token is revoked; if the flow table entry times out, the flow table entry is revoked. This invention improves the rate of RTP voice acquisition and storage resource utilization, adapts to high-volume voice acquisition scenarios, and reduces server processing load.
