Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0021] The invention provides a device and method for remote and precise measurement of the vertical displacement of the foundation, such as figure 1 As shown, the device sequentially includes a laser light source, a first reflector, a second reflector, a focusing lens and a CCD along the optical path, wherein:

[0022] The first reflector and the second reflector are 45° reflectors, the first reflector receives the horizontal light emitted by the laser light source, changes the horizontal light by 90° clockwise on the horizontal plane and reflects it to the second reflector , the second reflector changes the horizontal light by 90° clockwise on the horizontal plane again and reflects it to the focusing lens. imaging.

Abstract

The invention discloses a remote and precise foundation vertical displacement measurement device and method. The remote and precise foundation vertical displacement measurement device comprises a laser source, a first mirror, a second mirror, a focusing lens and a charge coupled device in sequence along an optical path, wherein the first mirror and the second mirror are 45-DEG mirrors; the first mirror receives horizontal light emitted by the laser source, changes the horizontal light for 90 DEG along a clockwise direction in a horizontal plane and reflects the light to the second mirror; thesecond mirror changes the horizontal light for 90 DEG again along the clockwise direction in the horizontal plane and reflects the light to the focusing lens; and the focusing lens focuses the horizontal light to the receiving screen of the charge coupled device, a light spot is obtained on the receiving screen, and imaging on the screen is realized. The remote and precise foundation vertical displacement measurement device and method provided by the invention can accurately measure the displacement of the foundation in a vertical direction, and the measurement difficulty is reduced.

Description

technical field [0001] The invention belongs to the field of optical precision measurement, and in particular relates to a device and method for remote and precise measurement of vertical displacement of foundation. Background technique [0002] At present, the construction of railways, highways and bridges has put forward higher and higher requirements for the control of foundation stability, especially the construction standards and technical requirements of high-speed railways are often much higher than ordinary railways. In order to ensure the stability and safety of high-speed driving, High-speed railways must ensure high track stability. The vertical displacement of the foundation will cause the rails to bend and even the road surface to break, which will bring great hidden dangers to traffic and building safety. The invention provides a method for remotely and precisely measuring the vertical displacement of the foundation, which can accurately measure the displaceme...
