基于RS 485总线的ADS1258数据采集网络系统设计与实现
Design and implementation of ADS1258 data acquisition network system based on RS 485 bus
摘要
Abstract
In order to accurately acquire the multi-channel analog signals at different sites in the spaceflight measurement field,a acquisition system was designed and implemented,which has 6 sensor nodes for 1 meter,and each node has 10-chan-nel analog signal. The Spartan-6 FPGA is taken as the core chip of the system to control the analog-to-digital conversion module with 24-bit,RS 485 bus transmission module with 40 Mb/s,and USB interface module. The system can simplify the previous test system greatly,improve the reliability of data acquisition and stability of system working,and is widely used in the space-flight test system with high precision requirement.关键词
