Dynamic monitoring system device for tailing dam body by three-dimensional laser scanning

Abstract

The invention discloses a dynamic monitoring system device for a tailing dam body by three-dimensional laser scanning. The dynamic monitoring system device mainly comprises a mechanical unit, a laser data acquisition unit, a control driving and feedback unit, and a communication and upper computer unit. In the device, the laser data acquisition unit is used for acquiring scene polar radius information of the surface of the tailing dam body; the control driving and feedback unit is used for driving the laser data acquisition unit to rotate in the horizontal dimension and vertical dimension, toscan the large scene on the surface of the tailing dam body at a constant speed and to acquire angle information in the horizontal dimension and the vertical dimension in real time; the communicationand upper computer unit is used for transmitting the acquired distance information and the acquired angle information to an upper computer through a high-speed data acquisition card; and software of the upper computer is used for processing the scene polar radius and the rotation angle information in the horizontal dimension and the vertical dimension to recover a real three-dimensional image of the scene, building a tailing dam body standard point cloud model in an ideal state, and storing the model into a database as an intelligent monitoring comparison template. During dynamic scanning of the device, qualitative and quantitative estimation for unexpected disasters is realized by using a dynamic monitoring algorithm through comparison with the template; operators and managers can immediately start corresponding emergency plans to avoid further expansion of the disasters.

Description

technical field [0001] The invention relates to a non-contact measurement technology, in particular to a non-contact dynamic on-line monitoring system device for three-dimensional laser scanning tailings dam body. Background technique [0002] In the "Twelfth Five-Year Plan" development plan for national safety production, there are clear requirements for the installation of online monitoring system devices for third-class and above tailings ponds within a limited period. The 3D laser scanning tailings dam dynamic monitoring system device is a typical prototype of the tailings dam on-line monitoring system, which meets the needs of the era for safe and steady development, and is of great significance to the protection of the country and people's life and property safety. [0003] Foreign countries have formed a monitoring and early warning system that includes functions such as on-site real-time data collection, comprehensive analysis of data, and safety alarms for tailings ...
