Abstract

This paper describes an online realtime data acquisition system. The design utilizes ARM singleboard computers that bring very low power requirements, portability and lightweightness. We have implemented a unified approach to acquire, transfer and store the measurements. The approach takes advantages of SeedLink protocol to establish online realtime data flows between the components of the system. Communication over IPv4 rely on secure virtual private networks. The system features remote management of data logger and all connected devices. For purposes of testing and technology showcase we’ve implemented support for a range of variometer-type magnetometers.
