摘要
PROBLEM TO BE SOLVED: To provide a landslide disaster sensor and a landslide disaster monitor system which have simple constitutions and can be easily installed and are hardly affected by natural environment conditions in detection of landslide disasters.;SOLUTION: A movable hard ball is provided in a sensor part 40, and a piezoelectric element is provided in a moving end of the hard ball in the sensor part 40. The sensor part 40 is freely slidably fixed in a housing 34 by a coiled spring 42. The housing 34 is buried in the ground. When the attitude of the housing 34 is changed by a landslide disaster, the hard ball collides with the piezoelectric element to generate an electric signal. The landslide disaster is detected on the basis of this electric signal.;COPYRIGHT: (C)2002,JPO
