A dynamic measurement device for the inclination angle of the launch tube

Abstract

The invention discloses a device and a method for dynamically measuring a tilting angle of a launch canister. The device comprises an inclined quartz accelerometer, a horizontal quartz accelerometer, an MEMS (micro-electromechanical systems) gyroscope, a wedge-shaped body, a signal collecting and processing module, a power source module, an outer casing, and a connector, wherein the inclined quartz accelerometer is used for measuring the gravity acceleration component which forms an included angle of 45 degrees with the axial direction of the launch canister, and a pitch angle of the launch canister under the static condition is obtained by a trigonometric function relation; the horizontal quartz accelerometer is used for measuring a roll angle of a vehicle body; when the launch canister is adjusted, the pitch angle speed is measured by the MEMS gyroscope, and is integrated, so as to obtain the dynamic pitch angle. The device has the advantages that the problem of poor measuring accuracy at large tilting angle in the traditional tilting angle measuring device is solved; the measuring range is large, the measuring accuracy is high, the dynamic measuring is realized, and the device is especially suitable for dynamically measuring the tilting angle of the launch canister under the vertical launching condition.

Description

technical field [0001] The invention relates to the technical field of engineering measurement, in particular to an inclination measuring device for measuring the dynamic inclination of a launch tube. Background technique [0002] The launching vehicle needs to adjust the shooting angle of the launching tube (launching rack) before combat, and its inclination adjustment range is usually -10°~+100°. In order to ensure that the initial firing angle of the missile is accurate, a high-precision inclination measuring device must be used to measure the inclination of the launch tube. Existing inclinometers usually use accelerometers to sense the earth's gravitational acceleration, so as to determine the angle between the accelerometer measurement axis and the horizontal plane. Because the accelerometer contains measurement errors, when the inclination angle increases, the inclination measurement resolution of the accelerometer will continue to deteriorate. Therefore, the range of...
