Attitude measurement device for parachuting tail end sensitive device

Abstract

The invention discloses an attitude measurement device for a parachuting tail end sensitive device. The attitude measurement device comprises a geomagnetic data acquisition module, a gyroscope data acquisition module, an acceleration data acquisition module, a data processing module, a data recording module, a power supply module and a communication module. In the parachuting process of the terminal sensitive device, the geomagnetic data acquisition module acquires three-axis geomagnetic field data of the device; the gyroscope data acquisition module acquires three-axis angular rate data of the device; the acceleration data acquisition module acquires three-axis acceleration data of the device; the data recording module receives the information of the data processing module and performs high-speed storage; the power module is responsible for supplying power to the measuring device; the communication module is used for transmitting data of the device and receiving an instruction; and flight attitude information of the tail end sensitive device in the parachuting process is deduced through inversion calculation of the collected data.

Description

technical field [0001] The invention relates to an attitude measuring device of equipment, in particular to an attitude measuring device of a parachute terminal sensitive device. [0002] technical background [0003] The parachute is a flexible soft aerodynamic deceleration device widely used. After the parachute of the terminal sensitive device is thrown out, the axis of the projectile body forms a certain angle with the vertical direction. Through the guiding function of the friction disc, the device is driven to realize synchronous rotation and landing. sports. After the system is stable, the final sensitive device searches for the target from the outside to the inside in the form of a helix. This process is the steady-state scanning movement stage. and so on. The different structural parts of the terminal sensitive device of the parachute adopt different design schemes, which will have different effects on the falling process of the terminal sensitive device. In order ...

[0004] The application number is: 201610724566.8, and the patent name is: A patent for the application of a missile-borne magnetic combination attitude measurement device provides a device attitude measurement device. Attitude measurement device, in order to more comprehensively measure the falling attitude information of this terminal sensitive device, it is necessary to use multiple sensors for measurement at the same time, and because there are large differences in the motion states of the terminal sensitive device in different axes, the general measurement device adopts a single The range sensor will produce a large error. In order to meet the measurement accuracy, it is necessary to use sensors with different ranges in different axes.
