Real-time measurement device and method for evolution of shore section morphology

Abstract

The invention relates to a real-time measurement device and method for evolution of shore section morphology. The device comprises a box body, a single chip microcomputer, and a data storage and transmission module, wherein the lower bottom and rear side of the box body are respectively connected with a column-shaped fixed cylinder and a fixed plate, a rotary shaft of a stepmotor in the box body protrudes the upper surface of the box body so as to be connected with a transverse rod, the top of the rotary shaft of the stepmotor is provided with a rotary angle sensor, the upper surface of the transverse rod is provided with a level instrument, an n-shaped equipment installation rack at the front end of the transverse rod is provided with a motor and a laser range finder and an inclination sensor that are driven by the n-shaped equipment installation rack, the rear end of the transverse rod is provided with a vertical rod that rotates around the rotary shaft of the stepmotor along with the transverse rod, and a wide-angle camera tilting downwards is installed on the outer side, facing the front end of the transverse rod, at the upper part of the vertical rod. The method comprises steps of installing the device on the wall or the top of a column-shaped body; determining a spatial position of the device; and allowing the stepmotor to rotate to a first angle and the laser range finder and the inclination sensor to rotate, and measuring a distance between a target body of any inclination and the laser range finder. The device is easy to install, is unattended, and delivers a moreaccurate measurement result.

Description

technical field [0001] The invention relates to a laser profile measurement device, more specifically, to a real-time profile measurement device and method for the evolution characteristics of coast and beach profiles. Background technique [0002] Sandy coasts are valuable natural resources and eco-tourism resources in the world. With the development of economy and society and the improvement of people's living standards, the demand for beach tourism is increasing. However, with the impact of global climate change, sea level rise, and human activities such as nearshore sand mining and marine structures, sandy coasts around the world are generally affected by erosion. The measured data of beach profiles in different years, different seasons, before and after strong storms and other periods is an important basis for studying the law and evolution trend of beach erosion and sedimentation, and formulating protection strategies. On the one hand, the long-term and repeated measu...

Problems solved by technology

On the one hand, the long-term and repeated measurement of the beach profile will consume a lot of manpower and material resources; Personal casualties and loss of equipment

[0003] The Chinese patent with the notification number CN 103697858B discloses the device and technology of "a sea cliff erosion scale measurement device and its measurement method", which is used to measure the two-dimensional profile data of sea cliff erosion. Due to the limitation of the device, the invention The content involved can only measure the erosion of sea cliffs, but cannot measure the erosion of beaches. It is suitable for higher sea cliffs, but not suitable for sandy beaches with very gentle slopes; in addition, due to the comparison of beach sediments Soft, and the pendant in the invention is susceptible to swings due to environmental factors such as strong winds, resulting in manual errors in multi-period repeated measurements
