ware is constructed by the accurate data converterADuC7026 with an ARM7TDM IMCU core inside, and Ethernet controller RTL8019AS, as well as the design of software. The A /D, D /A converting and data p rocessing are ac2 comp lished by ADuc7026, and the data transmitting and monitoring are p rocessed by Ethernet. The circuit is sim2 p le, and the system has high Signal - to - Noise, low cost and great p rospects.
