Industry 4.0

Sammanfattning: This scientific report has mainly studied the concept of Industry 4.0 and the possibility to send data from a temperature sensor to the cloud, a process which is an example of the term Internet of Things. The study has been conducted for the consultant business Rejlers to give the CEO as well as the Technical Manager a broader view of how they could implement IoT on behalf of costumers in the future. In order to show a clearer picture a pilot system has been created where data has been handled and transformed into different steps on its way to the cloud. Before these steps where implemented a thorough study to define a clear approach to solve the assignment on and compare the hardware options and the software options available was made. By following a sketch that was presented together with the assignment the structure of the report was based on a true example as a potential costumer would ask for. From the background of the preliminary study started the concrete phase where physical quantities should be handled and converted into digital data. Among those choices at hand further investigation was made in addition to the pre-study since a practical understanding for the components is required to make a clear decision that does not just work on paper but is possible to realize. The result of the thesis is a pilot system that can be used in order to explain in a clearer way the communication concept of Industry 4.0. By combining the previous knowledge from “Industry 3.0” where sensors are connected with a PLC and add a communication to the cloud we can create a more dynamic analysis. The ability to access data, key figures and error messages wherever there is internet connection opens up which can lead to faster decisions and increased efficiency. The pilot system has through communication and data management measured a physical quantity with a sensor, converted this signal within a PLC, sent it to a gateway which in turn transferred this data to a server in the cloud.
