Entwicklung eines Robotersystems für die Synchronisation und Datenmanagement von EIT- und Dopplermessungen

Development of a Robotic System for Synchronization and Data Management of EIT and Doppler Measurements in Bubbly Column Experiments

General Setting

Electrical Impedance Tomography (EIT) is a non-invasive imaging technology based where a conductivity profile inside a medium is reconstructed based on voltage measurements on its boundary. At iMEK, within the context of the Collaborative Research Center CRC1615, a 3D EIT system to monitor chemical processes is being developed. In order to bring bubble size distributions in the reactor together with electrical measurements this work aims to couple those measurements and automize the control of the system and the storage of the derived data.

Task Description:

The primary objective of this Project Work is to develop a comprehensive system that controls the position of a probe using a robotic arm, synchronizes Electrical Impedance Tomography (EIT) and Doppler probe measurements with the robot control, and manages the data efficiently through a real-time database system for bubbly column experiments.

Key Tasks:

1. Control System Development:

   • Design and implement a control system using a robotic arm to precisely position the measurement probes within the bubbly column.

   • Develop algorithms to ensure accurate and repeatable positioning, taking into account the dynamic nature of the bubbly column environment.

2. Synchronization Implementation:

   • Develop a method for the synchronization of EIT measurements, Doppler probe measurements, and robot control signals.

   • Ensure minimal latency in communication between the devices to maintain real-time data acquisition integrity.

3. Data Labeling and Acquisition:

   • Implement a robust data acquisition system capable of capturing and labeling Doppler probe and EIT data concurrently.

   • Ensure the captured data is accurately labeled with time stamps and probe positions for subsequent analysis.

4. System Integration and Testing:

   • Integrate the robotic arm, EIT, and Doppler systems with the bubbly column setup.

   • Conduct comprehensive testing to verify the functionality and reliability of the integrated system.

   • Calibrate the system to optimize measurement accuracy and repeatability.

5. Database Design and Management:

   • Design a scalable database schema to store EIT and Doppler measurement data.

   • Develop real-time data writing capabilities to the database, ensuring data is instantly recorded and accessible for analysis.

6. Documentation and Reporting:

   • Document the design, development, and testing processes thoroughly.

   • Prepare a detailed report summarizing the methodology, results, and potential areas for future work or improvement.

Deliverables:

• A fully integrated robotic system for probe control within a bubbly column.

• A synchronized data acquisition and labeling setup for EIT and Doppler measurements.

• A functional, real-time capable database for storing and accessing measurement data.

• Comprehensive documentation and a final project report.
