ACEP at Work: BlackBox Project Logbook – Project Update
The BlackBox Project consists of the design, construction and testing of a remote data acquisition system. The goal of the project is to develop a fully self-contained system that can be left in the field unmonitored for extended periods of time.
The BlackBox is now online and fully operational from remote access. A virtual private network (VPN) was created with the router support software, eCatcher. The connection to the BlackBox was then established through a secure shell (SSH) protocol.
An experimental setup was built in order to test the I/O interface. The software packages had to be compiled and installed so that the hardware signals could be read. As a result, another important milestone, the proof of concept with I/O interface was achieved. Data acquisition routines are now currently being worked on. (As of now a prototype routine for continuous data acquisition was successfully established.)
A network file system (NFS) drive was created on the Buffalo Terastation. Preliminary results were obtained using ‘iozone’ and gave an insight of how the data should be transferred between the I/O interface and the Terastation. The I/O interface still needs to automatically mount the remote drive in order to access it, which is a work in progress.
Minor issues were encountered and resolved:
The root filesystem was corrupted. To solve this, a new distribution of fedora 20 with a lighter desktop environment was installed.
The CMOS battery of the BlackBox computer had to be replaced in order for the system to retain correct date and time settings.
