【Abstract】 When improving the controller of automatic arc-suppressing device, the author redesigned data collection system based on AD1674 converter in order to remove defect that the old system cannot measure accurately and get steady output data and suppress interference very well. Improved data collection system can meet requirement of wide range input signal of automatic arc-suppressing device and its experimental operation and field showed that it has higher accuracy of measurement and better behavior than the old data collection system.更多还原
