The invention relates to a measuring point automatic configuration method of an engine test bed data acquisition system. The method comprises the steps of generating engine measuring point information, establishing test bed data acquisition channel information, selecting to-be-matched measuring points and data acquisition software, screening available data acquisition channels which are non-rack channels, automatically matching the engine measuring point information with channel information of a test bed rack, and generating data acquisition configuration. According to the invention, the engine measuring points are automatically matched with the channels of the test bed rack, and data acquisition configuration is quickly generated, so that the manual processing time is greatly shortened, and configuration errors are reduced.

The application discloses a fracturing working condition monitoring method and system based on a virtual serial port data interception technology, which can efficiently collect operation parameters and fracturing construction parameters of field fracturing equipment, and ensure data compatibility through protocol conversion, and then safely transmit the parameters to a fracturing instrument vehicle computer. By starting virtual serial port setting software, seamless docking of physical serial ports and virtual serial ports is realized, which not only improves the flexibility of data reading, but also ensures the integrity and accuracy of data. After being buffered and checked on the instrument vehicle computer, the data is fed back to the data acquisition software of the fracturing vehicle in real time, and the other way is efficiently sent to the designated serial port through the virtual serial port, realizing the bidirectional flow of data. The read data is preprocessed, the key parameters are extracted, and are transmitted to the oilfield cloud data center in real time, providing solid data support for remote monitoring and intelligent analysis, thereby significantly improving the efficiency and intelligent level of fracturing construction.
