摘要
对于SHCAN61系列现场总线智能仪表的检测,设计了一种集自动标定、老化检测等功能于一体的检测试验台。设计和实现了试验台控制系统,并利用现场总线进行数据采集处理,利用串行总线(USB)作为与PC机的数据传输接口,解决了61系列仪表的标定和检测问题。实验表明,其具有快速方便、简单易用、精确稳定等特点,满足工作精度的需要。
A test bench with automatic calibration and aging detection functions for SHCAN61 Field Bus intelligent instruments is proposed. The Field Bus is used for processing digital signals, and USB as the interface to PC. Experiment shows that this system realizes the designed functions and has the advantages of easy use, accuracy, stability and low cost.
