Abstract

The present invention relates to a debris flow monitoring and early warning system. The system comprises fixing steel cables, a disconnection sensor, a wireless transmission device, a remote warning device and the like. The fixing steel cables and the disconnection sensor are installed in a valley with debris flow hidden dangers. When debris flows occur, the steel cables are flown off, the wireless transmission device immediately sends the signal to the remote warning device, and then the remote warning device sends out warning information. The debris flow monitoring and early warning system can realize functions such as disaster information remote transmission and field real-time early warning, has the characteristics of being simple in setting, low in cost and strong in practicability, and can be widely applied to debris flow disaster early warning.

Description

A kind of debris flow monitoring pre-warning system
Technical field
The invention belongs to geologic hazard safety monitoring early warning field, be specifically related to a kind of early warning system based on line-breakage sensor and Radio Transmission Technology, a situation arises can to reflect rubble flow in real time, sends a warning in time.
Background technology
China is one of the most serious country of geologic hazard in the world, and the accident caused by geologic hazard is appeared in the newspapers end repeatly.Over nearly 10 years, personnel death's nearly 10000 people have been caused due to avalanche, landslide, rubble flow in the whole nation, and reach people more than 900 every year on average, the casualties caused with rubble flow in three is maximum, there is the features such as wide, the sudden and destructiveness of distribution is strong, all cause huge life and property loss every year.
Rubble flow often breaks out suddenly, breaks with tremendous force, and rolls downwards along steep gully, and mountain valley, just as thunderous, can be carried huge stone, go out outside ditch within very short time by a large amount of silt stone, greatly destructive, causes significant damage usually to human life's property.Set up practical early warning system in rubble flow prone district very necessary, early early warning in a second is with regard to bull point safety.
Summary of the invention
The invention provides a kind of debris flow monitoring pre-warning system based on line-breakage sensor and Radio Transmission Technology, this system not only can realize the monitoring and warning of rubble flow, also effectively can reduce monitoring cost, be conducive to popularization and application.
Technical scheme of the present invention is: adopt line-breakage sensor and radio transmitting device as front-end equipment, be installed in the gully of rubble flow potential safety hazard.When rubble flow occurs, can trigger line-breakage sensor and produce switching signal, warning information is sent to the remote supervisory of residential block, downstream by radio transmitting device at once simultaneously, and send audible and visible alarm immediately, prompting personnel withdraw immediately.
Accompanying drawing explanation
Accompanying drawing is system schematic of the present invention.
In figure: 1, fixing wirerope; 2, line-breakage sensor; 3, radio transmitting device; 4, remote supervisory.
Embodiment
Native system generally comprises system and comprises the parts such as fixing wirerope, line-breakage sensor, radio transmitting device and remote supervisory.Below in conjunction with accompanying drawing, the present invention is further described.
1, fixing wirerope
Fixing wirerope [1] comprises a thick jackstay and a thin secondary wirerope.Jackstay is installed in certain altitude place at the bottom of distance debris flow gully, and this is highly the threshold value of debris flow early-warning, and two ends are fixed on sidewall.Secondary wirerope one end connects line-breakage sensor, and the other end and jackstay centre position are fixed.
2, line-breakage sensor
Line-breakage sensor [2] is a kind of switchgear that only just can flick open circuit when being subject to certain pulling force, is fixed and is arranged on sidewall.When debris flow scale reaches jackstay height, line-breakage sensor is subject to impact tension and flicks, and produces a switching signal.After major-minor wirerope is thrust, sensor still can stay scene, conveniently reclaims in the future.In order to increase reliability, native system adopts and disconnects the line-breakage sensor that value of thrust is 200N (being less than secondary wirerope maximum pull intensity), avoids the wrong report interference because the factors such as external impurities, animal, weather in natural situation cause.
3, radio transmitting device
Radio transmitting device [3] is connected with line-breakage sensor [2], adopts sun power and accumulator uninterrupted power supply.Once receive chopping signal, the information that sends rapidly is to remote supervisory [4].
4, remote supervisory
Remote supervisory [4] mainly comprises warning light, loudspeaker and wireless receiving module, is installed in densely populated place district, debris flow gully downstream.Sending audible and visible alarm at once when receiving the signal that radio transmitting device [3] sends, reminding people to withdraw in time, taking care.
Innovation
The present invention is a kind of debris flow monitoring pre-warning system, and it have employed more cheap line-breakage sensor, fully takes into account terseness and practicality.When rubble flow occurs, given the alarm in time by radio transmitting device and remote supervisory, make downstream resident obtain disaster information rapidly and accurately, effectively ensure that life security.Operation system setting is easy, and cost is lower, practical, great popularization.

Claims (4)

1. a debris flow monitoring pre-warning system, is characterized in that, this system comprises fixing wirerope, line-breakage sensor, radio transmitting device and remote supervisory.
2. debris flow monitoring pre-warning system according to claim 1, is characterized in that, described fixing wirerope, comprises a thick jackstay and a thin secondary wirerope.Jackstay is installed in certain altitude place at the bottom of distance debris flow gully, and this is highly the threshold value of debris flow early-warning.Jackstay two ends are fixed on sidewall, and secondary wirerope connects line-breakage sensor and jackstay.
3. debris flow monitoring pre-warning system according to claim 1, is characterized in that, described line-breakage sensor is fixed on sidewall, only just can flick open circuit when being subject to certain pulling force.When generation rubble flow, when scale reaches jackstay height, line-breakage sensor is subject to impact tension and flicks, and produces a switching signal.After major-minor wirerope is thrust, sensor still can stay scene, conveniently reclaims in the future.
4. debris flow monitoring pre-warning system according to claim 1, it is characterized in that, described radio transmitting device, after receiving the chopping signal of sensor rapidly by information transmission to the remote supervisory being installed in residential block, debris flow gully downstream, alarm device gives the alarm immediately.
