摘　　要：某化工项目蒸发设备为非规则形状,需要采用体积值来实现联锁控制,采用Excel软件的散点图功能处理工程标定数据,获得合适的拟合曲线,并根据仪表吹气原理及仪表信号处理原理进行CFC语言编程设计并封装调用。根据标定数据选取部分点进行PLC仿真,误差在允许范围内,满足工艺运行的控制要求。可为其他相似的控制系统的信号在不同量纲间转换提供技术参考。Evaporation process is controlled by the volume signal of evaporator in a chemical plant. Complete processing of vessel’s calibration data via Excel scatter diagram, and get fitting curves. Program the curves in CFC language according to transducer measurement theory. Simulate five points chosen from calibration data, the deviation is allowed and the control requirement is satisfied. This method of dimensions transformation from kPa to dm3 can be referred to those similar control systems.
