Abstract

The invention discloses a data acquisition method and device and a data acquisition card. The data acquisition method is applied to a data acquisition card of an oscillograph, and comprises the following steps: receiving a data acquisition instruction sent by an upper computer; acquiring sampling data according to the data acquisition instruction; storing the sampling data to a storage unit; and sending the sampling data stored in the storage unit to the upper computer through a PCIE interface according to a preset transmission frequency. According to the embodiment of the invention, when the oscillograph collects data, adjustment can be carried out according to the sampling rate and the storage depth based on the storage unit, the PCIE transmission rate can be adapted, data processing can be completed in time, and the problems of data loss and the like can be avoided as much as possible.

Description

technical field [0001] The application belongs to the field of electric power technology, and in particular relates to a data acquisition method, device, equipment, data acquisition card and computer storage medium. Background technique [0002] The oscilloscope is mainly an automatic recording device used to monitor the operation status of the power system. At present, when the oscilloscope collects data, it can realize high-speed data acquisition based on a high-speed serial computer bus (Peripheral Component Interconnect Express, PCIE). [0003] However, in related technologies, some defects in the data collected by the oscilloscope sometimes cannot adapt to the performance of PCIE high-speed data transmission, data processing is not timely, and problems such as data loss may occur. Contents of the invention [0004] The embodiment of the present application provides a data acquisition method, device, equipment, data acquisition card and computer storage medium, which c...
