反应堆冷却剂系统温度测量通道标定试验(RCP63)中传统的数据采集方法为人工采集法,存在处理效率低、易发生人因失误、可归档性差等问题.针对这些问题,通过研究核电厂中数字化仪控系统(DCS)数据采集特点,在DCS数据库中插入数据脚本的方式进行数据采集.该方法成功应用于红沿河核电厂3号机组,提高了工作效率,减少了可能的人因失误环节.“,”The traditional data acquisition method for reactor coolant system temperature measurement channel calibration test (RCP63) is artificial acquisition method.It is with low processing efficiency,prone to human error,poor archiving and other issues.For these problems,this paper studies the DCS (digital instrument control system) data acquisition characteristics of nuclear power plants,and uses the database data in the DCS (digital instrument control system) for data acquisition.The method had been successfully applied to the unit 3 of Hongyanhe Nuclear Power Plant,which increased the work efficiency and reduced the potential human errors.
