Oil analysis instrument data acquisition and transmission is one of the important links in oil monitoring and analysis.At present,there are more and more oil analysis instruments and equipment with their own analysis software,but there are generally inconsistent information transfer interfaces,only export and transmission of current analysis oil sample data,inability to extract and transmit historical data content and non-analysis result files content,and no encryption information transmission function.Aimed at those problems,a set of integrated oil analysis instrument data acquisition and transmission solutions were proposed.This method can obtain the information source to be transmitted through the operating system API function and Hook technology,can obtain the required information through the integrated data format analysis algorithm,and then can obtain the information by scanning the 2D code at the receiving end and restore in the reverse by presenting and segmenting the data information by the 2D code.At the same time,the platform-based development concept was applied in this method to realize the universal processing of the instrument-side software and the receiving-side software,and integrate the data encryption and decryption functions.The application in the instruments such as spectral analysis and wear particle analysis instruments shows that this method realizes the collection and transmission of information such as spectral data and wear particle analysis images,and achieves good engineering effect.The design and application of this method provide a new solution for data acquisition and safe transmission of oil analysis instruments.
