摘　　要：针对流量计在线检定数字化、自动化和智能化的要求,基于RS-485通讯接口和MODBUS RTU通讯方式,设计了以PC为核心的智能流量计在线检定信息采集系统。该系统可以实时采集两台流量计的流量数据,分析表间相对误差,并将分析得到的结果输出保存为文件。初步试用的结果表明,该系统结构简单,连接方便,通讯实时性强,运行稳定,可以为流量计"标准表比对法"在线检定提供便利。In view of the requirement of digitization,automation and intelligence,the information collection system was designed,taking PC as the core,based on RS-485 and MODBUS RTU communication,which was used for on-line calibration of intelligent flowmeter.The system could collect data of two flowmeters in real time,analyze the relative error and save the data and analysis as a file.Preliminary trial results show that the system had a simple structure easy to connect to communicate in real time stably.It is convenient for the application of the standard meter comparison method to online calibration of the instrument.
