Industrial Wireless Sensors Network with an Iot-lnternet of things-platform

摘要

In this work we present the development and implementation of an industrial communication system for remote monitoring and management of industrial processes. The system is implemented based on the IoT (Internet of Things) model. This way, we connected multiple sensors to a wireless system which sends the information to a cloud server. Base on the fact that the gathered data from the sensors is available on the internet, we are able to visualize, analyze and download the data from all over the world. Thus, we additionally developed an SCADA system which obtains the information from the cloud server and it supervises the average values not pass a threshold value. If the value is above the threshold, we communicate the SCADA (Supervisory Control and Data Acquisition) system with a PLC (Programmable Logic Controller) that performs an action. Furthermore, the SCADA system allows to manually control the PLC. Finally, we present the mathematical modeling of the implemented network by using Petri models and we analyze the networking system by using network packet measurements and protocol analyzers.
