Weir-Jones Engineering Consultants has developed the Seismic ‘Rockfall™ ’
Detection System (SRFDS) which is an evolutionary alternative to traditional
slide fence technology. This revolutionary system relies upon acoustic
signature recognition to determine if and when rocks or other hazardous
debris fall onto the right of way. The exact size and location of the hazard is
determined in real time by utilizing highly sensitive seismic sensors together
with a 24-bit data acquisition system.
