Data acquisition method

The invention relates to the technical field of data acquisition, and discloses a data acquisition method, which is used for acquiring a plurality of acquisition parameters, each acquisition parameter comprises an initial address and a data length, and the plurality of acquisition parameters are divided into at least one acquisition block. The method comprises the following steps of: acquiring a plurality of acquisition parameters in a plurality of acquisition blocks, generating a block acquisition instruction based on the acquisition blocks to acquire data of all acquisition parameters in the acquisition blocks, and analyzing the acquired data to obtain the data of the acquisition parameters, so that the data of a plurality of acquisition parameters can be acquired in the same batch without polling acquired equipment one by one based on each acquisition parameter; therefore, the acquisition time of the controller for data acquisition is provided, and the real-time performance of the controller is improved. 本
