Artificial intelligence in ISES measureserver® for remote experiment control

Abstract

The paper deals with the area of Internet School Experimental System (ISES) remote experiments in general and its core module called ISES Measureserver ®. In particular ISES Measureserver® is, in fact, a finite state machine, serving for the measured data accumulation, processing and providing communication in the server-client system. Recently, we replenished ISES Measureserver ® by a new functionality, namely diagnostics of the connected to the RE physical hardware, using the artificial intelligence solutions. In the introduction, the state of the art of ISES remote experiments is described. In the next chapter a consideration for the applying of proper artificial intelligence method to improve the Measureserver® reliability is made. We focused on the cognitive Fault Diagnosis System (FDS) intended for distributed sensor networks. FDS makes advantage of spatial and temporal relationship among sensors connected to RE physical hardware to give the information for reduction of the influence of failures, ill effecting the Measureserver® functioning. The lower layer uses Change Detection Test (CDT) based on Hidden Markov models (HMM) configured to detect variations in the relationships among couples of sensors. Changes in the HMM are detected by inspecting the corresponding likelihood. The output information provided by the CDT lower layer is then passed to the cognitive higher layer collecting information to discriminate among faults, changes in the environment and false positive. The intended improvement is the increase of the reliability, monitoring of the state and the fast remedy of the functioning of remote experiments in case of malfunction. Proposed diagnostics solution will contribute to improvement to remote experiments reliability and to a wider acceptance of this new ICT technology. © Springer International Publishing Switzerland 2014
