AI Technical Summary

Technical Problem

The prior art is difficult to achieve accurate detection of the impact intensity of mudslides, resulting in the inability to achieve effective early warning of bridges.

Method used

An early warning device including a detection unit, a data processing and decision-making unit and a display screen is designed. The detection unit consists of multiple integrated sensing devices, which are arranged in the center of the upstream river channel of the bridge. When the impact intensity exceeds the set threshold, the integrated sensing device breaks. The data processing and decision-making unit judges the fracture situation through the current data and goes to the control unit. Issue an early warning command and the display screen displays the corresponding early warning information.

Benefits of technology

Accurate detection of the impact intensity of mudslides has been achieved, the accuracy and efficiency of early warning has been improved, the detection cost has been reduced, and large-scale implementation has been facilitated.

Abstract

The invention discloses an early warning device for debris flow washout of a bridge, and the device comprises a detection unit which is disposed at the center of an upstream river channel of the bridge and comprises a plurality of sensing integrated devices which are connected with each other, and the sensing integrated devices are broken when the impact strength in the river channel is greater than a set threshold value; the data processing and decision-making units are arranged on the two sides of the river channel, are connected with the detection unit and are used for collecting and processing the current data transmitted by the detection unit so as to judge whether the sensing integrated device is broken or not; and the display screen is arranged in front of the entrances on the two sides of the bridge, a control unit is arranged in the display screen, and the control unit selects early warning information according to the early warning instruction issued by the data processing and decision-making unit and displays the early warning information on the display screen. The early warning system and the early warning method have the beneficial effects that the impact strength at a specified position can be accurately detected, the early warning accuracy is improved, the impact strength in a river channel can be monitored in real time, and the early warning efficiency is improved.
