The invention discloses a landslide disaster remote monitoring system, and relates to a landslide monitoring system. The structure of the landslide disaster remote monitoring system comprises the following: a rainfall sensor node (100) and an infrared displacement sensor node (200) are connected with a convergent node (300) respectively to form a wireless sensing network (700), and the wireless sensing network (700), a GSM/GPRS network (800), a terminal GSM/GPRS module (400), a terminal processor (500), and a GIS display screen (600) are connected in turn. The landslide disaster remote monitoring system is used for real-time monitoring of actual rainfall intensity and rainfall duration of landslide and collapse areas, state information of landslide and collapse, and sliding information of dangerous rocks, can objectively and comprehensively monitor and evaluate the rainfall threshold of critical landslide, the evolutive process and the state of landslide, and the landslide and collapse level, and provides a novel real-time monitoring path for landslide and collapse early alarm.
