Description

Wendelstein 7-X (W7-X) has been finally commissioned in 2015 and is now in its first stage of operation. Due to the complex structural design and a limited life time of some components, each step of W7-X commissioning and operation is carefully monitored by a considerable amount of different sensors. Unlike the fast machine control or the fast experiment data acquisition, the machine instrumentation (MI) works on a time scale of seconds to minutes and is not part of the W7-X control system. All MI data are captured and stored within the W7-X experiment archive. However the provided data browsing and reporting tools, like the Databrowser, are only of limited use when it comes to the approval of the structural integrity by mechanical engineers, due to the large volume of sensors and aquired data The paper presents the W7-X approach for the on-line MI monitoring and structural integrity evaluation, based on the W7-X data archive and the incorporated JSON-based Web-API. It is shown how a client program, written in the high-level language MATLAB, allows the top-level supervision of multiple MI sensors and sensor types, while giving an easy access to individual sensors and signals, if necessary. The derived and implemented algorithms are a basis for a future deployment in a service oriented W7-X infrastructure. Furthermore it is presented how the program can be deployed for tasks beyond the initial scope.
