Problems solved by technology

[0005] For professional instruments, the measurement of horizontal displacement, vertical displacement and distance change is mainly done by total station, level, theodolite, displacement meter, etc. However, the measurement of total station, level and theodolite needs to be done manually. The monitoring frequency of the measured object is not only very limited, but also has relatively high requirements for operators because of precision instruments; for automated total stations, levels, and theodolites, although these automated measuring equipment can automatically measure Requirements, but the cost is expensive, and long-term monitoring in the field or in harsh environments still requires technicians to guard and maintain the instrument on site

[0061] In order to monitor the three-dimensional deformation of the measured body, i.e. the horizontal displacement of the measured body, the vertical displacement and the distance change between the fixed point and the measured point, the difference between embodiment 3 of the present invention and embodiment 1 is:

[0062] 1) The light source transmitter is a laser rangefinder, which has a built-in high-performance 5V rechargeable lithium battery; the laser rangefinder has a spot focusing device, which is used to measure the object under test and the laser beam while emitting laser light as a light source. The accuracy of the displacement data between the range finders can reach 1mm. The laser rangefinder transmits the obtained displacement data to the data collection and output module, and after filtering and amplifying processing by the data collection and output module, it is output together with the information obtained by the position sensor.

[0063] 2) The position se...

Description

[0001] technical field [0002] The invention relates to a non-contact automatic displacement monitoring device, in particular to a non-contact automatic displacement monitoring device for existing engineering deformation under geological disaster conditions. [0003] Background technique [0004] There are many types of existing deformation monitoring, mainly using professional instruments and sensors to continuously observe the deformation phenomenon of deformable bodies, analyze the deformation behavior of deformable bodies, and predict the development trend of deformable body deformation. In engineering surveying, the most representative deformation bodies are tunnels, bridges, highways, dams, slopes, subways, high-rise buildings, etc. The content of deformation monitoring is determined according to the nature of the deformable body and the ground conditions. It mainly observes the horizontal displacement, vertical displacement of the measured body and the distance cha...
