Abstract: Data is a key element supporting intelligent manufacturing.With the upgrading of manufacturing,the factory continuously introduces equipment from different manufacturers with different protocols and different interfaces.Data from that equipment collected has the characteristics of multi-source heterogeneity and constantly updated.Traditional data acquisition systems are customized for specific equipment,which is difficult to achieve parallel acquisition of multi-source heterogeneous data and real-time dynamic configuration.To solve these problems,a configurable acquisition method based on Field Programmable Gate Array (FPGA) was presented.Multi-source heterogeneous data were collected in parallel to ensure the real-time data acquisition.A configurable data acquisition scheme was designed to enhance the flexibility of data acquisition.A verification scheme was designed to verify the effectiveness of the proposed method.

Key words: field programmable gate array, multi-source heterogeneity, data acquisition, dynamic reconfiguration

摘要： 数据是支撑智能制造的关键要素,对生产各阶段数据的有效采集是实现“人—机—物—环境”制造全要素互联互通的基础。随着制造升级发展,车间不断引入来自不同厂家,具有不同协议、不同接口的设备,使得待采集数据多源异构且采集需求不断变化。传统数据采集设备难以并行采集多源异构数据、难以根据采集需求的动态变化对采集设备动态配置,因此提出一种基于现场可编程门阵列(FPGA)的多源异构数据并行可配置采集方法,基于FPGA硬件并行完成对多源异构数据的监测,保证数据采集实时性;研究FPGA动态重构技术并设计了数据采集可配置方法,提升数据采集灵活性;最后,设计了验证方案,验证了所提方法的有效性。
