The instrument design aims to deploy nearly 1000 fibers over the field of view requiring to control nearly 2000 actuators by the same number of CAN bus stepper motor drives through 15 independent CAN bus networks. All this massive traffic and extensive wiring can be merged down into a single Ethernet line by means of 3 Ethernet to Multi-CAN Gateways (EtherCAN) and an Ethernet switch. This is possible today due to emerging multi-CAN ARM microcontrollers, which provide highly embedded solutions suited to be located closer to the sensitive areas of the instrument, where power dissipation and space are critical.","PeriodicalId":215432,"journal":{"name":"Software and Cyberinfrastructure for Astronomy VI","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121542842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
{"title":"Artificial intelligence agent to assist the telescope operation as a troubleshooter using a voice-user interface","authors":"Manuel Huertas Lopez, Agustín Núñez Castain","doi":"10.1117/12.2560948","DOIUrl":"https://doi.org/10.1117/12.2560948","url":null,"abstract":"The Gran Telescopio Canarias (GTC) is a 10.4-meter optical-infrared telescope located at the Roque de los Muchachos Observatory on the island of La Palma, Spain. Like any modern telescope, it has a high degree of automation and complexity, being made up of hundreds of subsystems that work in a coordinated way to carry out a scientific observation. Even the control system is at a good level of maturity, on certain occasions, when an unwanted event occurs, it sometimes becomes difficult to identify its cause and thus restore the system to its nominal state efficiently. There are three pillars that can be worked on to reduce the time lost due to technical failures: reduce the frequency of occurrence, reduce the impact after the occurrence or increase the detection capacity. However, the system will never be fault-free, so it will always be necessary to develop a system that allows a diagnosis to be made. Ideally, the diagnosis should be made with the information provided by the control system itself and other services that verify the status of the platform, and therefore, with minimal interaction with the user. On the other hand, due to the great variety of faults, and the need to carry out the diagnosis as soon as possible, a voice user interface will be used, in such a way that the operator can indicate the fault that is occurring, using natural language. As a proof of concept, a subsystem diagnostic service has been developed, a thermal monitoring subsystem, a service in charge of providing thermal values of the telescope structure to build a thermal model. During the implementation of this diagnostic service, the need for changes in the software design has already been identified to include the information necessary to generate a good diagnosis, which will indicate to the operator: which part is failing, where it is located and the instruction to replace it. Consequently, it has been proven that extending it to the rest of the control system will bring immediate benefits.","PeriodicalId":215432,"journal":{"name":"Software and Cyberinfrastructure for Astronomy VI","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115382625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
