Research of data acquisition controller for DO based on FPGA

Abstract

Real-time sampling control of A/D converter TLC5510 is realized with EP13T144C8-FPGA device of cyclone, which improved the real-time property of data acquisition for DO. Frequency division of system clock and control of A/D sampling are implemented respectively by VHDL language. High-speed storage and sending of transform data are achieved in combination design of FIFO memory. Simulation results under QuartusII development platform are presented at last. The real-time investigation and control of DO could be realized to raise the water quality of sewage treatment. © 2012 Springer-Verlag.
