Embedded systems are devices designed for special purposes, which perform their predetermined tasks efficiently. The purpose of connecting such devices to a network is to distribute the data generated during their operation among each other or other devices. Embedded data acquisition systems measure physical quantities and provide the measurement data to other systems. There are many protocols used for different applications in widespread, ethernet-based networks.

My task was to create a distributed data acquisition system prototype that measures physical quantities of different types according to which it distributes the measured data. That, in this case, means the different handling of measurement data from highly varying quantities sampled at a higher frequency, i.e. acceleration, angular velocity and magnetic field strength, and other data from sensors that measure temperature, air pressure, humidity and illumination.

The system I designed complies the requirements above and can be a basis for developing a distributed data acquisition system that could be used in practice.
