Combined infrared displacement sensor network node for monitoring mountain massif coast

Abstract

The invention discloses a joined infrared displacement sensor network node for monitoring landslide, and relates to a slope displacement sensor for monitoring landslide in real time. The structure of the joined infrared displacement sensor network node combined according to a triangle comprises the following: the joined infrared displacement sensor network node consists of a primary node (10), a first secondary node (20) and a second secondary node (30) which are arranged on vertexes of the locked monitoring triangle respectively. The structure of the joined infrared displacement sensor network node combined according to a quadrangle comprises the following: the joined infrared displacement sensor network node consists of a primary node (10), a first secondary node (20), a second secondary node (30) and a third secondary node (40) which are arranged on vertexes of the locked monitoring quadrangle respectively. The joined infrared displacement sensor network node can reliably monitor lateral displacement, longitudinal displacement, altitude difference three-dimensional displacement and collapse information of a slope. When the sensing nodes are buried by gliding mass, loss information of the buried sensing nodes can also be accurately calculated, so that the aim of objectively identifying and evaluating position, state and level of landslide and collapse is achieved. The joined infrared displacement sensor network node has the advantages of low price, high sensitivity, flexible radio-frequency control and small power consumption, and meets the characteristic requirements of the sensing nodes.

Description

technology field. [0001] The invention relates to a side slope displacement sensor for real-time monitoring of landslides, in particular to a combined infrared displacement sensor network node for monitoring landslides. Background technique [0002] Landslide refers to the phenomenon that the rock and soil mass on the slope slides down under the action of gravity along a certain weak surface (or weak zone) due to various reasons, while collapse refers to the rock block or rock-soil mixture separated from the parent rock. The process of falling or rolling down a slope. The outbreak of landslides and avalanches not only causes losses to people's lives and property, especially mountainous railways are often threatened by landslides and avalanches. Since the founding of the People's Republic of China, disasters that endanger traffic safety have occurred almost every year. Especially since the new century, my country's trains have continued to speed up, which has put forward hig...

Problems solved by technology

[0003] Existing landslides and collapse direct testing methods mainly include conventional monitoring displacement sensor and GPS global satellite positioning system; conventional monitoring displacement sensor is to adopt various direct or indirect displacement sensors, such as angle Sensors and telescopic displacement sensors sense the displacement of the active slope relative to the stable slope. This type of sensor has the problem of inconvenient installation and construction. However, ordinary GPS technology is used to monitor landslides and collapses, and the measurement accuracy is not optimistic. If static differential GPS is used Technology, its equipment is more expensive

[0004] In particular, it should be pointed out that due to the suddenness and randomness of landslides and the complexity of the landslide evolution process, a small number of conventional monitoring displacement sensors are arranged in the monitoring area, and its sampling distribution is difficult to reliably represent the actual state and grade of the landslide; A large number of conventional monitoring displacement sensors, due to the risk of being submerged by landslides, collapses, and smashed, the above-mentioned displacement sensors and GPS global satellite positioning devices have become bottlenecks in terms of price, communication and energy consumption, and it is difficult to put them into engineering implementation
