Basic modular structure for modular inertial navigation system

Abstract

The present invention provides a basic modular structure for a modular inertial navigation system used for producing a modular inertial navigation product, the basic modular structure comprises a module a and a module d, which are used for mounting a gyro, a module b used for composition of a frame, and a module c used for mounting a circuit, the module a and the module b have same peripheral assembly tenon-and-mortise joint structures, the precision of tenon-and-mortise joint tooth grooves of both sides are processed according IT6 level, the tenon-and-mortise joint tooth grooves are used to achieve positioning function, and when in system assembly, 2 to 5 modules a and 2 to 4 modules b are selected for forming a system according to system requirements. The basic modular structure is wide in adaptability, convenient in combination, flexible, and easy to produce in large scale, in high degree of engineering application, and the like. The basic modular structure can use the high-precision positioning tenon-and-mortise joint structures to achieve a reliable connection, the modules are rational and clear in division of labor, take into account the accuracy and environmental adaptability, can greatly simplify the production process of inertial navigation products, and shortens the development process, and can also meet most individual requirements of users.

Description

technical field [0001] The invention relates to the installation and fixing technology of an inertial navigation system. Background technique [0002] Inertial navigation system, as a necessary equipment for various high-performance vehicles, is being used more and more widely. Since various vehicles have their own characteristics, the inertial navigation systems used on them are quite different in shape, size, or environmental adaptability. This situation makes the structural design of the inertial navigation system extremely uncertain. Although the functions of the inertial navigation system are similar, the generalization of the structure cannot be realized even on systems with similar performance. This situation greatly delays the delivery cycle of inertial navigation products and greatly increases the workload of inertial navigation system designers, which is a difficult problem for all inertial navigation system designers.
