Abstract

The invention discloses a practical landslide pre-warning system. The practical landslide pre-warning system comprises a master control unit and a plurality of landslide sensors, wherein the master control unit comprises a wireless receiving module, a microprocessor, a short message module, a storage module, an audible and visual alarm, a state indication module and a receiving antenna; the landslide sensors comprise mechanical dual-shaft dip angle detection modules, wireless emitting modules, antennas and batteries; the landslide sensors are vertical to the horizontal plane and are buried into different positions of sites on which landslide possibly occurs, can be respectively set with different dip angle thresholds and are in a power-off state at ordinary times; and the master control unit is mounted in a house of people close to a landslide site, or enterprise and public institutions or other place in which power can be continuously supplied. The practical landslide pre-warning system has the advantages that the power supply problem of the landslide sensors is solved; the landslide sensors are simple in internal structure, supplied with power through dry batteries, small in volume and low in cost and can be used massively; and the landslide sensors can be buried into multiple positions at the same site, so that the landslide monitoring range is expanded, and the practicability is strong.

Description

technical field

[0001] The invention relates to a landslide early warning technology, in particular to a wireless landslide early warning system which is suitable for protecting the life safety of personnel and can be installed and used in large quantities. Background technique

[0002] As a kind of geological disaster, landslides will cause up to hundreds of millions of property losses every year in our country, and at the same time endanger people's lives. Landslide monitoring is to detect the deformation of landslides. Due to the high randomness of landslides and the slow-changing process of landslide deformation, continuous long-term monitoring is usually required. At present, landslide detection is divided into two methods: on-site monitoring and off-site monitoring: on-site monitoring is to install landslide monitoring equipment at possible landslide points; off-site monitoring is to install landslide monitoring equipment in places far away from landslide points throug...

Embodiment

[0029] The landslide early warning system in this embodiment is composed of 1 main control unit and 6 landslide sensors paired with it. The landslide sensor and the main control unit adopt wireless one-way communication. The landslide sensor can only transmit wireless signals, the main control unit can only receive wireless signals, and multiple landslide sensors cannot communicate with each other. Six landslide sensors are buried in different locations where landslides may occur, and one master control unit is installed in the homes of residents near the landslide point. A total of 3 inclination thresholds are set for the 6 landslide sensors, and the same inclination threshold is set for every 2 landslide sensors. The set inclination thresholds are 3°, 6°, and 9°, respectively, corresponding to the three stages of creep deformation, sharp deformation and sliding of the landslide.
