改进的EDM在熔盐堆热工回路控制系统中的应用

The Application of Improved EDM in the Thermal Loop Control System of Molten Salt Reactor

EDM(Extensible Display Manager)作为EPICS环境下的人机界面(Human Machine Interface)开发软件,已经被广泛应用到大型实验装置和工业控制系统中。采用现有版本的EDM作为熔盐堆热工回路控制系统HMI开发的工具,由于其Dynamic Symbol控件的运动速率是固定的,无法动态反映熔盐的实际流速。为使熔盐流速能够通过HMI人机界面动态地呈现,方便操纵员实时观察熔盐流速并做出相应的判断,需要界面显示的熔盐运动速率与流量计测定的熔盐流量相关联。针对此问题对现有EDM软件进行了相关的改进,克服了其局限性。

EDM （Extensible Display Manager）, one example of an EPICS display manager, has been usually used on large Experimental Equipment and Industrial Control System. The exiting EDM is used as a development tool of HMI in the thermal loop control system of molten salt reactor, but its motion rate is fixed and could not display the motion rate of molten salt dynamically in the HMI. The motion rate of molten salt should be associated with flow which flow meter measures to display the motion rate of molten salt dynamic in the interface and operator can observe and judge conveniently. In order to overcome the limitation, we improved the existing EDM.
