| Abstract: | In allusion to the particularity of various application environments for weak signal acquisition,a distributed multi-channel weak current acquisition system is designed.Based on data-centric distributed architecture,the system is divided into three modules with logic and physical,such as current collection node,data storage and processing nodes and the man-machine interface.Among them,the current collection node using monolithic smart structure,being easy to implement a local digital and transmission,data s... |
