Slope disaster monitoring system and method based on multi-line laser radar

Abstract

The invention provides a slope disaster monitoring system and method based on a multi-line laser radar. The method comprises the following steps: step a, the multi-line laser radar is started for self-test and generates point cloud data; b, the calculation core judges whether an obstacle exists in the multi-line laser radar monitoring area or not according to the point cloud data; the calculationcore transmits the monitoring data and the alarm data to the field equipment according to the obstacle information; c, the field equipment transmits the monitoring data and the alarm data to a monitoring center; and d, the monitoring center judges whether the obstacle affects driving or not. According to the slope disaster monitoring system and method based on the multi-line laser radar, rich target feature information can be obtained to achieve high-precision obstacle detection, the obstacle invasion state of a monitoring area can be obtained in real time, and meanwhile the detection distanceof a single set of equipment is far larger than the level of existing equipment; and the requirements of high real-time performance, high reliability, large-range monitoring and easy construction onsite can be met.

Description

technical field [0001] The invention belongs to the field of track monitoring, in particular to a slope disaster monitoring system and method based on multi-line laser radar. Background technique [0002] Slopes along the railway line are widely distributed, numerous in number and with great structural differences, and are prone to landslides, mudslides, landslides and other disasters during the rainy season, posing a great threat to train operation. Therefore, reliable monitoring of disaster intrusion along railway lines is a key and urgent need. By monitoring whether the slope disaster has affected the train running line, the information of the current monitoring scene can be effectively obtained, so as to perform intrusion alarm and other purposes. [0003] At present, the intrusion monitoring method along the railway mainly relies on single-line lidar to collect environmental information, but the amount of information collected by single-line lidar on the environment is...

Problems solved by technology

At present, the traditional slope geodetic method and the Beidou method are both point-based measurements, which can only detect local slope deformation variables, with small coverage, low sampling density, and difficult construction; while spaceborne InSAR (Aperture Radar Interferometry Technology) (INSAR, Interferometric Synthetic Aperture Radar; abbreviation: interferometric radar measurement) has a long detection cycle and cannot meet the real-time requirements; while the single-line lidar method of detecting obstacle intrusion in the track area cannot obtain rich three-dimensional shape information of obstacles, and the detection reliability is low. Low and small detection range
