Multi-channel Synchronous Data Acquisition System Based on Ethernet

摘要

A multi-channel synchronous data acquisition system based on Ethernet is designed in this paper. It consists of three parts including synchronous data acquisition cards, Ethernet switch and data processing computer. ARM9 controller is applied in the data acquisition card to implement data acquisition and Ethernet communication, working without operating system (OS). Practical test results prove that the system is feasible and efficient.
