Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Such as figure 2 As shown, the two-dimensional space running track tester based on the dual-axis fiber optic gyroscope of the present invention is mainly composed of five parts, including the dual-axis fiber optic gyroscope, the interface system, the mileage meter, the host computer and the upper computer.

[0026] The mileage meter, host computer and upper computer are basically the same as the existing track detector, and the main difference is reflected in the two-axis fiber optic gyro and the interface system.

[0027] The dual-axis fiber optic gyroscope of the present invention is composed of two parts, a hardware circuit and an optical path. The optical path part consists of semiconductor light source, fiber coupler, pol...

Abstract

The invention discloses a two dimensional space track tester based on a double-axis optical fiber gyro, and belongs to the field of moving track engineering test. The tester comprises a host computer, an interface system connected with the host computer, a trochometer, an upper computer and an optical fiber gyro connected with the interface system, wherein the optical fiber gyro is a double-axis optical fiber gyro formed by integrating two single-axis optical fiber gyros into a gyro body; and sensitive axes of the double-axis optical fiber gyro are mutually perpendicular and can simultaneously measure running tracks in two directions on the same plane. The tester integrates the two single-axis optical fiber gyros into one gyro body, and sensor information is provided for the space runningtrack tester through the one double-axis optical fiber gyro. At the same time, only one set of interface equipment needs to be matched so as to solve the problems of large volume and lower integration of the prior track tester, and simplify the electric design simultaneously.

Description

technical field [0001] The invention relates to an instrument for two-dimensional space engineering test using an optical fiber gyroscope, in particular to a two-dimensional space running trajectory tester based on a two-axis optical fiber gyroscope. Background technique [0002] The fiber optic gyroscope inertial device is a key sensitive measurement device for a stable measurement system. It can establish a running trajectory reference coordinate system during operation, be sensitive to the angular velocity information of its motion, and output data to the upper computer of the running trajectory detection instrument through a high-speed interface system. To provide corresponding data for accurately measuring the height of the running track and the deformation of the track, and then carry out the running track test in two-dimensional space. [0003] The most commonly used existing two-dimensional space running track testing equipment is the equipment used to detect running...
