Glacier movement monitoring system and method

Abstract

The invention discloses a glacier movement monitoring system and method. The method comprises the following steps: arranging acquisition nodes on the surface of glacier; acquiring the surface three-dimensional movement acceleration, the surface elevation and the deflection of the glacier in the acquisition nodes; transmitting the surface three-dimensional movement acceleration, the surface elevation and the deflection of the glacier to a ground base station; obtaining a glacier displacement amount according to the surface three-dimensional movement acceleration, the surface elevation and the deflection of the glacier; judging that whether three or more acquisition nodes in the acquisition nodes have displacement amounts or not; and trigging an alarm mechanism when the judgment result shows that the three or more acquisition nodes in the acquisition nodes have displacement amounts. The automatic monitoring method does not need artificial intervention, so manpower and material resources are saved; and a high-precision MEMS chip and a Sirfstarii II positioning system are adopted, and an RF wireless radiofrequency technology is used to aggregate onsite data, so the precision of monitoring data and the transmission reliability are guaranteed.

Description

technical field [0001] The invention relates to the field of glacier movement monitoring, in particular to a glacier movement monitoring method and system. Background technique [0002] Global warming has led to intensified melting of glaciers, resulting in a significant reduction in the volume and area of ​​glaciers. In recent decades, the melting of glaciers has intensified again, leading to the disappearance of many small glaciers, which has also caused a series of water resources and ecological environment problems. Therefore, it is particularly important to monitor glacier movement with modern scientific and technological means. With the development of modern science and technology, the focus of glacier research is only limited to the monitoring of glacier area and volume, while more and more countries are focusing on the monitoring of glacier movement posture. [0003] For the monitoring of glacier movement posture, conventional means are to monitor by hand-held GPS,...

AI Technical Summary

Problems solved by technology

[0003] For the monitoring of glacier movement posture, the conventional means are to monitor by hand-held GPS, setting measuring piles, etc. This kind of method needs to manually collect GPS data, manually measure the distance between the measuring pile and the fixed pile to reflect the relative position change of the glacier body , this type of method is relatively backward and wastes manpower and material resources, not scientific enough

The movement of glaciers is monitored by using satellite remote sensing image maps. This method combines GIS technology and uses DEM data to extract relevant information. The process is relatively complicated and requires relatively high technical personnel. will also have varying degrees of impact, thereby affecting the accuracy of the data
