一个多路数据自动采集系统的设计与实现

Design and reality of a multiplex route data acquisition system

科研、生产实践中经常需要长时间不间断的监测几百路电阻阻值的微小变化,并要求对采集到的数据进行及时分析.因此,设计了一个多路数据自动采集系统,以HP34970A作为数据采集器以满足测试的精度和速度要求,自行设计的单片机控制系统可以满足监测路数的扩充,结合安捷伦公司配置的benchlink软件和自行设计的采集自动化软件,实现数据采集的自动化数据分析.实际应用证明,该系统可靠性高、成本低、数据分析及时.

The minor changes of hundreds of resistance value need to be monitored for a long time incessancy, and the acquisitioned data need to be analysed timely.Accordingly,a multiplex route automatic acquisitioned system is designed.In the system,a data acquisition system,HP34970A,which satisfies the demand of precision,is selected.A monolithic control system which is used to expand the number of monitored route is designed.With the benchlink software of agilent technology company and with automatic acquisition software which is designed by us,data can be collected automatically and analysed timely.The application verifies that the system is an excellent data acquisition system.
