Practical landslide pre-warning system

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...

Problems solved by technology

[0003] Chinese Patent Specification "A Landslide Intelligent Monitoring System and Method" (Application No.: 201711154824.4) and "Metal Mine" Journal Issue 10, 2016 "Design of a New Wireless Remote Monitoring System for Landslides" both use solar energy and rechargeable Complementary battery power supply, its disadvantages are: solar power generation equipment is large in size, high in cost, and vulnerable to man-made damage

[0004] The defects of the landslide alarm system disclosed in the Chinese patent specification "A Landslide Alarm System" (authorized announcement number: CN 106023532B) are: complex structure, high cost and maintenance costs, and need to use wired power supply or larger capacity solar power generation

[0005] Chinese Patent Specification "A Video-Based Debris Flow or Landslide Alarm System" (Authorized Announcement Number: CN103093579B) and "Coal Mine Safety" Journal 2017 Volume 48 Issue 5 Paper "Slope Radar Monitoring and Early Warning Mechanism and Application Example Analysis" paper , all adopt off-site monitoring schemes, and the sensors do not need to be installed at the landslide site. The disadvantages are: the sensors are more expensive, observation points need to be built, equipment maintenance costs are high, and the automatic alarm algorithm is immature and requires human intervention.
