Design and Implementation of a High-accuracy Data Acquisition and Control System |
| |
| Abstract: | Data acquisition and control system is of significant importance to modern inspection and con-trol technology ,subsequently the system performance requirement increases dramatically .In this paper ,a data acquisition and control system with increasable channel number is proposed ,in which single-master and multi-slaves are employed .More precisely , communication network of the whole system is accom-plished with CAN bus ,a central controller is applied to command node controllers ,and each node control-ler achieves signal acquisition and control at its corresponding node by using a 3-channel A/D converter and a 6-channel D/A converter . |
