Abstract

The invention discloses an integrated landslide monitoring sensor and belongs to the field of sensors. The integrated landslide monitoring sensor solves the problems that an existing landslide monitoring method is long in measuring period, low in accuracy or complex in system and high in cost. The integrated landslide monitoring sensor comprises a shell, a ground auger, an installation guide pipe, a support, a communication circuit, a signal collecting circuit, multiple sets of moisture measuring units and an antenna. The shell is composed of a shell body and an upper cover, the ground auger is arranged at the bottom end of the shell body, and the installation guide pipe is arranged on the inner wall of the shell body. The support is arranged in the shell body from top to bottom. The upper end and the lower end of the support are connected with the upper cover and the ground anger of the shell respectively. The moisture measuring units are dispersed on the support. The signal collecting circuit is arranged on the support. The communication circuit and the antenna are arranged in the upper cover of the shell. The moisture content signal output end of each set of moisture measuring unit is connected with the moisture content signal input end of the signal collecting circuit. The signal collecting circuit sends collected signals through the antenna.

Description

technical field [0001] The invention relates to an integrated landslide monitoring sensor and belongs to the field of sensors. Background technique [0002] Landslides are geological disasters caused by heavy rain and weathering that make the mountains overwhelmed, disconnected from the weak areas of the mountains, and cause the overall decline. Debris flows are also counted as a landslide phenomenon. [0003] As a natural phenomenon, landslides cause a large number of casualties and property losses every year, and it does great harm to bridges, water conservancy, construction and other projects. According to incomplete statistics, in the past 10 years, the number of deaths and The average number of missing persons is 1,000 per year, causing direct economic losses of 3.86 billion yuan, among which landslides are the most serious. Therefore, it is of great significance to monitor it. [0004] There are many methods and means for landslide monitoring at home and abroad. Due ...
