A system for monitoring an earth and/or rock body

摘要

A system (10) for monitoring an earth and/or rock body (12) includes a plurality of sensors (14) spaced apart on a surface (16) of the body (12) for providing respective first signals indicative of the displacement of the surface (16) with respect to the body (12). A plurality of interfaces (18) are respectively associated with the sensors (14) for receiving the first signals and producing second signals derived from the first signals. Control means (20) remote from and successively actuating the interfaces (18) provide the second signals to the control means (20).
