WELFBA: a data communications project
Microprocessor-Design created a Modula-2 application for a dedicated PC:
This application had to be multi-tasking as otherwise data following a larger earthquake could be ignored. It also had to be fail-safe so that data could be saved to local disk if and while the VAX was unresponsive. This could happen in the event of a large earthquake resulting in a loss of mains power, and only the PC had a UPS.
The application designed by Microprocessor-Design has run continuously for several years. Its output data is used to estimate the magnitude of significant earthquakes and alert the duty seismologist in almost real-time.
