Tiivistelmä
In industrial environments a huge amount of history is collected often through thousands of different signals, but how can it be made sure that everything is being collected successfully? Data is often stored in historian databases in industrial environments and those can become large quickly. Modern distributed control systems can have thousands of signals delivering continuous stream of data.
Even if one has access to a database, which not many should have, it requires skills to find and analyze any useful data. This problem can be solved by having a tool that does that for the user. Web-based applications that run on a browser are on the rise and this signal diagnostic tool is made to be used on browser and is part of Valmet automation’s historian configurator.
This thesis is about the process of developing a new tool for Valmet. From the requirements to design and from design to implementation. In the end its suitability is evaluated, and how it meets the requirements.
Signal diagnostics tool is strictly for looking at a single signal data and does not edit it in any way. Data is fetched from a database and then displayed on the screen for the user in chart and in table format. This removes the problem that not all has access to databases and skills to use them.
