Embodiment Construction

[0013] Embodiment of the present invention: a wireless intelligent monitoring and early warning method for slope geological disasters based on acoustic emission, an acoustic emission sensor is buried inside the road slope body, and the acoustic emission signal collected by the acoustic emission sensor at the initial stage of the slope disaster is used, and the The collected signal is sent to the data receiver installed in the safe position of the road by wireless transmission; the data receiver transmits the signal to the data processing computer through the communication cable along the road; the data processing computer analyzes and processes the signal, and according to The results of the processing will make corresponding level of early warning measures, and the early warning information will be sent to the early warning display screen of the disaster road section through the communication cable to remind passing vehicles to take corresponding disaster reduction and preventi...

Abstract

The invention discloses a wireless intelligent monitoring and early-warning method and device for slope geological hazard based on acoustic emission. The method comprises the following steps: embedding an acoustic emission sensor in a slope, acquiring an acoustic emission signal at an early slope catastrophe stage by the acoustic emission sensor, and sending the acquired signal to a data receiver arranged at a safe position of a road in a wireless transmission mode; transmitting the signal to a data processing computer through a communication cable along the road by the data receiver; and analyzing and processing the signal and taking early-warning measures at a corresponding level according to the processing result by the data processing computer, and then transmitting early-warning information to an early-warning display screen at a hazard road section trough the communication cable so as to remind passing vehicles of taking the corresponding hazard reduction and prevention measures.

Description

technical field [0001] The invention relates to the field of traffic engineering, in particular to a wireless intelligent monitoring and early warning method and device for slope geological disasters based on acoustic emission. Background technique [0002] At present, with the continuous and rapid development of my country's economy and the advancement of urbanization, the number of open-air slopes formed by a large number of road constructions, natural weathering and water erosion and other factors that require disaster management are increasing year by year. According to our investigation and statistics, there are more than 20 side slopes in the K 2006 to K2010+200 section of Zhensheng Expressway, most of which are not stable overall and have a potential landslide tendency. The resulting slope geological disasters will bring serious threats to people's lives and property safety, and cause heavy losses to the national economy. [0003] Guizhou is located on the east side ...
