Study And Implementation Of Detector Remote Monitoring System

Daya Bay Reactor Neutrino Experiment(Daya Bay)uses the electron-antineutrino produced by the reactor to find the third neutrino-oscillation,and precisely measure the mixing angle with 10 standard deviations.Due to the great success of Daya Bay Experiment,the another hot issue,measurement of neutrino mass sequence,is on agenda,so the second phase of Daya Bay Experiment,Jiangmen Underground Neutrino Experiment,emerges as the require.JUNO will measure the neutrino mass sequence and the oscillation parameters by measure the energy spectrum of reactor accurately,at the same times,it will also research some unknown issue about neutrino,such as supernova neutrino,solar neutrino and sterile neutrino,on a leading level in the international.In the experiment,the detector control system is an important guarantee of the subsystems' ordinary operation,it will monitor and control the subsystem with accuracy and for a long-term,also,it is required to give an alarm when in an abnormal situation.Monitoring and searching about the DCS data will be an important part in maintenance the experiment running in Daya Bay and JUNO when its construction is completed.In the work of this paper,firstly,studying the remote monitoring system of Daya Bay,analysing the method of building and the key technologies in the client and server,the server technologies are PHP and SQL,the client technologies are Java Script,Ajax and CSS.And then improving the remote monitoring system according the feedback in use,the improved system which has been in test running for three months is the preferred improvement program of Daya Bay detector remote monitoring system.Secondly,studying the two methods of data acquisition of JUNO,the one is the Archiver appliance in EPICS,and the other is the RCP platform developed by ourselves,and setting up the remote monitoring system based on the two methods of data storage of data acquisition respectively.Currently,the two remote monitoring system has run for 45 days in the test bed of JUNO.At last,through the test running of two systems,summarizes the appliance,advantages and disadvantages of the two systems.In this paper,the remote monitoring system based on Web is not only important in ensuring the normal operation,it also provides references to physics analysis.
