Multi-channel electrical power data acquisition system based on AD7606 and NIOSII

The principle and architecture of AD7606 are introduced in this paper. ADC control is realized with FPGA technology, acquisition and display of 8-channel synchronized electrical power data are achieved with embedded processor NIOS II of high performance, the system has some good performances as high-speed, good precision, and flexibility of control, it can be widely used in the field data acquisition.
