Asynchronous buffer read method in development of DAQ application for supporting research of hydraulic systems

Abstrakt

The paper presents a method of data acquisition from a DAQ card using a direct memory access (DMA) and an asynchronous read of data buffer with the FIFO queue. The method can be used to acquire measurement data in Windows™ system when the required read frequency is higher than the system’s clock frequency. The method was used in practice to measure high-speed pressure and position changes in a two cylinder hydraulic system with two-state fast switching valves.
