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 using Flex [1]). Through CAJ [2] interface, it fetches EPICS data including beam energy, beam current, lifetime and luminosity and so on. Then all data is displayed in a realtime 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.

  The China Spallation Neutron Source (CSNS) is planning to start construction in 2011 in China. The CSNS controls system will use EPICS as development platform. The scope of the controls system covers thousands of devices located in Linac, RCS and two transfer lines. The interface from the control system to the equipment will be through VME Power PC processors and embedded PLC as well as embedded IPC. The high level applications will choose XAL core and Eclipse platform. Oracle database is used to save historical data. This paper introduces controls preliminary design and progress. Some key technologies, prototypes,schedule and personnel plan are also discussed.
