Differential settlement monitoring instrument for high-speed rail

Abstract

The invention discloses a differential settlement monitoring instrument for a high-speed rail. The differential settlement monitoring instrument comprises a transmitting module and a receiving module which are respectively arranged on two measuring points, wherein the transmitting module comprises a semiconductor laser device and an optical conversion lens; the receiving module comprises a receiving plate, an imaging system, a line array complementary metal oxide semiconductor (CMOS) image sensor, a micro processor system and a network interface component, wherein a laser beam transmitted by the semiconductor laser device is converted into a horizontal-line-shaped laser beam for transmission by the optical conversion lens; and the receiving plate receives the horizontal-line-shaped laser beam and transmits the horizontal-line-shaped laser beam to the micro processor system for analysis and judgment through the imaging system and the line array CMOS image sensor to obtain a settlement value. The differential settlement monitoring instrument is simple and small in structure, low in cost and easy to mount and debug, works stably and reliably and is suitable for long-time engineering monitoring.

Description

technical field [0001] The invention mainly relates to the field of engineering quality testing equipment, in particular to a monitor suitable for differential settlement of high-speed rail. Background technique [0002] As the state has increased investment in infrastructure construction in recent years, my country's high-speed rail construction has achieved rapid development. Due to the high speed of the train and high safety requirements, the high-speed rail project has more stringent requirements on the roadbed than the construction of roads, bridges and ordinary railways. Generally, the settlement cannot exceed a few millimeters, otherwise it will directly affect the safe operation of the high-speed rail. into a serious disaster. [0003] In the prior art, a liquid level-type settlement deflection detection system connected with an electronic level is a relatively widely used settlement monitoring method at present. The connected liquid level settlement deflection det...
