At the start of the project, it was necessary to simplify the monitoring and maintenance of optical PoF PROFINET cables in the welding shop. Today we monitor the quality of about 6,000 optical cables through a single user-friendly system. The development and implementation of our own software tools and ThingWorx visualisations enabled us to produce a solution which not only provides information about the quality of signal in individual optical PoF PROFINET cables, but also about PROFINET stations, their firmware versions, data flows, damaged packets, current topology, etc. The solution also enables the monitoring of FESTO CPX valve terminal error reports. Besides that, we continue to think of additional functionalities.
The idea behind this project was to develop a brand-new condition monitoring system to monitor the Schuler PXL press lines, and thus help the maintenance department monitor key devices and values. Today the FIOT condition monitoring system monitors the two PXL press lines and their parameters, compressed air consumption, energy consumption, the flow rates and temperatures of cooling water, the temperatures of the main motors, pressing force values, vacuum, PROFINET networks, etc. The system, which is based on OPC communications and the ThingWorx IoT platform, can unlock many more opportunities – mobile phone visualisations, an alert subsystem, augmented reality and links to relevant documentation. Simply put, a user-friendly solution.
Třinecké železárny (Třinec Ironworks) needed to optimise and automate regular temperature measurements in many places on the shop floor. In the end, the customer and we agreed to use Monnit wireless sensors, which use a frequency of 868 MHz. The sensors were connected to an IoT gateway, and data started to be transmitted to the customer's own software platform.
In ŠKODA AUTO, a.s. Mladá Boleslav, we implemented a solution for wireless 24 V voltage quality monitoring in control cabinets. For the project, our company developed its own solution for the continuous monitoring of supply voltage, called AB-Tester. AB-Tester measures voltage in individual wires. At set intervals, it takes the maximum, minimum and medium voltage value, and wirelessly transmits the data to an IoT gateway, using a frequency of 868 MHz. The data is then processed and visualised by the ThingWorx platform.
In the case of a ŠKODA assembly line, we faced a great difficulty in developing a solution for continuous active and passive PROFINET network monitoring. The challenge lay in meeting the need for regular scanning of stations in the PROFINET network and providing the maintenance department with real-time information about potential alerts and PROFINET stations' failures. The solution we provided was based on our own software tools. The visualisation and business logic were created using the ThingWorx platform.
The management of Česká zbrojovka (Czech Arms Factory) identified the need for condition monitoring, which led to project initiation. What followed was an effort to assess the real applicability of this data and set priorities for a comprehensive solution. That was the reason why we suggested the use of Monnit wireless sensors, an IoT gateway, and standard visualisation of real-time data as well as historical developments. The result met the customer's expectations. It enabled the optimum selection and installation of sensors and helped plan further project stages. Furthermore, it proved cost efficient in the monitoring of compressed air quality. It turned out that there was potential to be realized. We’re currently developing a robust FIOT solution that will be based on the ThingWorx platform and OPC communications.
A very important and common component in the ŠKODA AUTO, a.s. welding shop is SEW frequency inverters. The idea behind our solution was the fact that the worsening condition of the mechanical parts of the technology, which were driven by the SEW motor, would result in a sudden increase of immediate output current from the inverter. We decided to monitor the inverter's output current values and their developments (e.g. gradual increases and sudden changes) over a long period. This enabled us to infer unwelcome changes to the condition of the technology's components. To collect the necessary data, we developed our own OPC server for SEW frequency inverters. To further process and visualise data, we use the ThingWorx platform.
For the ŠKODA AUTO, a.s. Kvasiny paint shop, we developed a solution for the continuous monitoring of PROFIBUS DP network quality. To collect data about PROFIBUS stations and telegrams, we use COMbricks hardware modules from PROCENTEC. We used the ThingWorx platform to develop a visualisation that shows alive and disconnected stations, repeated and failed queries, diagnostic reports, and failed communication logs on the basis of pre-set triggers.
Bosch is a company which is very involved in the implementation of Industry 4.0 principles. This enabled Bosch employees to closely cooperate with our specialists and develop a brand-new hands-on solution. How does it work? You have a tablet or mobile phone. It displays a real object or 3D model with controls (icons) that provide a whole range of information about the object (almost 250 measured values), without the need to leave the site. In addition, the object can be manipulated. You can also peek inside without having to use sophisticated equipment and hours of dismantling work. Apart from technological data monitoring, you’re also provided with the monitoring of thresholds, batch visualisation and access to relevant documentation.
The idea for the project came from ŠKODA's green factory scheme and the need for greater cost-efficiency. The aim of the project was to create a system that would enable the measuring, visualisation and comparison of electric power consumption values for given time periods in specific parts of the technology (machines, centres, and departments). During the first implementation stage, we installed almost 100 three-phase network analysers in 3 switch rooms. Data from the analysers (electric power consumption, electricity network quality – current, voltage, input, power factor, harmonic voltage distortion) is transferred to the KEPServerEX OPC server via the Modbus protocol, and then communicated to the unified FIOT smart maintenance platform.
