| description | The invention discloses a data acquisition method. The method comprises the following steps: step 1, acquiring a plurality of groups of simulation data samples in the same time period; step 2, converting the collected analog data sample into an oscillogram; step 3, scanning each oscillogram, retaining a part of waveforms located at the lower part, and erasing other waveforms to generate a sample waveform; step 4, generating a to-be-measured oscillogram by using the collected data; and step 5, comparing the to-be-measured oscillogram with the sample oscillogram to obtain an acquisition result. A data collector comprises a main control unit, the main control unit is connected with a memory, and the main control unit receives data collected by an external sensor, arranges and analyzes the data to obtain a data sample, and stores the obtained data sample in the memory to wait for calling. A plurality of same-period data are collected, and the sample precision is improved by adopting the modes of area coverage and |
