A WEB BASED REALTIME MONITOR ON EPICS DATA

Monitoring systems such as EDM and CSS are extremely important in EPICS system. Most of them are based on client/server(C/S). This paper designs and implements a web based realtime monitoring system on EPICS data. This system is based on browser and server(B/S). Through CAJ interface, It fetches EPICS data including beam energy, beam current, lifetime and luminosity and so on. Then all data is displayed in a real time chart in browser (IE or Firefox/Mozilla). The chart is refreshed every regular interval and can be zoomed and adjusted. Also, it provides data tips showing and full screen mode.
