利用GPIB并行总线实现对小野测器DF系列油耗仪的自动化控制

Auto Control of DF Series Fuel-consumption Apparatus with the GPIB Parallel Bus

日本小野测器生产的DF2420油耗仪功能全面,测试精度高,并配置有GPIB通讯接口,在国内应用较为普遍。作者采用了基于PCI总线的GPIB通讯扩展卡,利用VB语言+DLL库函数编写了计算机端的控制程序,实现了工控计算机对该油耗仪的远程控制和数据自动采集,使该油耗仪与其它内燃机测试设备有机结合,组成内燃机自动化测试成套设备,并避免了该油耗仪每次使用前所需要的繁杂的手动设置工作,提高了工作效率。

DF2420 fuel - consumption apparatus has a high precision with GPIB interface. The author designs a program to communicate message by the GPIB interface using Visual Basic and DLL. By this way, remote control and data collection are achieved following much higher efficiency.
