In the context of intelligent manufacturing and industrial self-control, this article focuses on the collaborative application of domestic field programmable gate arrays (FPGAs) and multi-channel synchronous sampling analog-to-digital converters (ADCs) to meet the demand for high-precision data acquisition and real-time control of mechatronic integrated CNC equipment. By analyzing the hardware programmable characteristics of domestic FPGAs such as Anlu Tang and Ziguang Tongchuang Logos series, and combining the high-precision synchronous sampling capabilities of domestic ADCs such as Linghui Lixin LHA7878 and Xindong Shenzhou ADCS8162 (24 bit/16 bit resolution, 8/16 channel synchronous acquisition), a multidimensional signal acquisition and real-time processing architecture for data control devices is constructed. Focus on researching key technologies such as signal conditioning circuit design, clock synchronization strategy, and hardware implementation of data processing algorithms, and verify system performance through industrial level application cases. The research results provide a solution for the deep integration of domestic core components in high-end equipment, helping to improve the independent controllability and reliability of CNC equipment.
