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
The present invention relates to the traffic engineering field, especially a kind of side slope geologic hazard wireless intelligent monitoring method for early warning and device based on acoustic emission.
Background technology
At present, along with the sustained and rapid development of China's economy and the propelling of urbanization, the side slope that the needs that factors such as the formed open slope of a large amount of highway constructions, natural weathering and water erosion form carry out hazard management increases year by year.Investigate statistics through us, K 2006 to the K2010+200 sections that the town wins highway just have more than 20 side slope, and most of resistances to overturning are bad, have the trend on potential landslide.The side slope geologic hazard that brings thus brings serious threat will for the people's safety of life and property, makes national economy suffer heavy losses.
Guizhou is located in Qinghai-Tibet east side, is subjected to the Qinghai-Tibet Platean to continue the grand influence that rises, and forms the geomorphologic landscape of high mountain gorge.Not only cause high slope " view " to be grown; And cause because the slump geologic hazard that causes of side slope unstability is very frequent, and have the advantages that scale is big, mechanism is complicated, harm is big, difficulty of prevention and cure is high, influence and restricting this regional society's economic development and strategy to develop western regions enforcement.
Along with a series of Important Project highly visible, or soon implement like " transferring electricity from the west to the east ", project of South-to-North water diversion, high speed and the construction of high-grade highway net etc.Undoubtedly, the further exploitation in this area also will bring more extensive, wider side slope geologic hazard and relevant environmental problem to demand urgently researching and solving.
Through the investigation statistics, about certain section short 5km of town's victory highway more than 20 side slope just arranged, most stable property is relatively poor, has the harm on potential landslide.The side slope geologic hazard that possibly bring thus brings serious threat will for the people's safety of life and property, makes national economy suffer heavy losses.
Summary of the invention
The objective of the invention is: a kind of side slope geologic hazard wireless intelligent monitoring method for early warning and device based on acoustic emission is provided; It carries out intelligent early-warning to the side slope disaster in real time; Effectively avoid the personnel that the side slope geologic hazard possibly bring and the loss of property, to overcome the deficiency of prior art.
The present invention is achieved in that the side slope geologic hazard wireless intelligent monitoring method for early warning based on acoustic emission; Bury calibrate AE sensor underground in slope of highway body inside; Utilize the acoustic emission signal of the side slope catastrophe initial stage that calibrate AE sensor collects, and the signal that collects is sent to the data sink that is installed in the road safety position with Wireless transmission mode; Data sink is transferred to signal in the data handling machine through highway telecommunication cable along the line; Data handling machine carries out analyzing and processing with signal; And make the early warning measure of appropriate level according to process result; Early warning information flows to the early warning display screen that the disaster highway section takes place through telecommunication cable, takes corresponding disaster reduction and prevention measure to remind vehicular traffic.
Side slope geologic hazard wireless intelligent monitoring prior-warning device based on acoustic emission comprises calibrate AE sensor, and calibrate AE sensor is connected with data sink; Data sink is connected with data handling machine, on process computer, is connected with the early warning display screen.
Calibrate AE sensor is more than 4.This is based on acoustic emission source difference positioning algorithm is confirmed when three-dimensional, when sensor number >=5, can reduce mushing error, and the acoustic emission source coordinate that calculates is also just more accurate; Can also realize simultaneously that potential landslide universe is carried out large-scale monitoring point arranges, guarantee the effectively reliable of data acquisition, the data analysis basis is provided for realizing potential sliding mass status monitoring and early warning.
Be wireless connections between calibrate AE sensor and the data sink.Effective like this data transfer equipment of avoiding is by artificial destruction or environmental corrosion, effective transmission of the data after also guaranteeing in the disaster generating process to take place with disaster.
Owing to adopted technique scheme; Compared with prior art; The present invention gathers the acoustic emission signal of the early stage catastrophe of side slope by calibrate AE sensor; The signal that collects is sent to the data sink that is installed in the road safety position with Wireless transmission mode; Be transferred in the computer of data analysis center by highway facilities such as communication cable along the line again and carry out analyzing and processing; And make the early warning measure of appropriate level according to process result; Early warning information flows to the early warning display screen that the disaster highway section takes place by communication cable; Take corresponding disaster reduction and prevention measure to remind vehicular traffic; Thereby reach the purpose of side slope disaster intelligent early-warning; Emergency processing when taking place for the side slope geological disaster provides valuable time, thereby effectively evades the personnel that the side slope geological disaster possibly bring and the heavy losses of property.Method of the present invention is simple, implements easily, and the apparatus structure that is adopted is simple, and is easy to make, with low cost, and result of use is good.
