The application provides a press operation information and operation and maintenance service edge computing system and method, which is independent of a press control PLC, comprises a dual-core edge computing controller, a data acquisition module, a communication module and sensors deployed on the press, has press information acquisition and data processing, fault diagnosis, motion pair temperature and friction block life analysis and prediction, remote data management and other functions, interacts with the main control PLC in real time to exchange press information data, and uploads the data information of the press to a cloud platform to provide support for remote service of the press. The application can obtain more press state information, effectively overcomes insufficient data analysis and processing capacity of the press main control PLC, and moves the detection sensors to the edge side, shortens the main control PLC scanning cycle, realizes real-time sensing and rapid response to the press operation information state, avoids overload, overheating, excessive wear and brake failure, and improves the safety, reliability and intelligent level of the press.

This invention provides a method and system for automatic vertex picking of DAS-based microseismic events, relating to the field of microseismic location technology. The method includes acquiring multi-channel data corresponding to microseismic events and performing demodulation analysis to form multi-channel waveform data; performing correlation analysis on the waveform data from different channels to establish an automatic picking correlation model; performing image transformation based on the automatic picking correlation model to form corresponding grayscale images; and performing location discrimination analysis based on the grayscale images to determine the event vertex channel. This method improves the interpretation accuracy and reliability of geological analysis of seismic images by removing noise while preserving geological structural features such as faults and strata.

The invention discloses an MVDR beam forming FPGA structure based on a multi-mode systolic array and an implementation method. The FPGA structure comprises a data acquisition module used for obtaining a sampling matrix of a floating point type; the FSM scheduling module is used for performing scheduling control on the multi-port storage RAM, the multi-mode calculation module and the data stream; the multi-mode calculation module comprises a division unit, a negation unit, a delay unit, a cache unit and a systolic array unit formed by N * N PE units, and is used for performing covariance matrix solving, LDL decomposition, triangular matrix and diagonal matrix inversion and calculating an optimal weight according to the solved inverse matrix; each PE unit is used for carrying out floating point complex number multiplication and floating point complex number accumulation operation on input data; and the multi-port memory RAM is provided with an X-dimensional read port and a Y-dimensional read / write port. The resource overhead is small, and the real-time performance and the hardware cost can be both considered.
