A Modular Inertial System Construction Method

Abstract

The invention provides a modularized inertial system construction method which can realize rapid development of an inertial system. The method comprises the following implementation steps: (1) constructing a plurality of functional modules according to a set performance parameter range; (2) respectively carrying out a functional test on each functional module, and adding the functional modules passing through the test into a hardware design library; (3) selecting the corresponding functional modules from the hardware design library according to requirements of performance indexes of the inertial system to be constructed; and (4) connecting all the functional modules according to a composition structure of the inertial system, testing system functions, carrying out PCB making and welding, and constructing to obtain an inertial navigation system meeting the requirements of the performance indexes. As the system adopts a circuit modularization design, if one module has a fault, only the module is replaced instead of replacing the whole circuit board, so that the workload of troubleshooting is greatly reduced; for the modularization design, a high-precision module can be easily used for replacing the existing low-precision module; and a product can be upgraded and is easy to maintain.

Description

technical field [0001] The invention relates to the technical field of inertial system design, in particular to a modular inertial system construction method. Background technique [0002] As a precision instrument that can independently measure the motion parameters of the carrier relative to the reference coordinate system, the inertial system is widely used in aviation, aerospace, weapons, navigation and other fields. Inertial system development units need to improve their core competitiveness to cope with the increasingly fierce market competition environment and Meet the diverse needs of users. The core competitiveness is reflected in providing users with high-performance and high-reliability products and services, reducing costs and shortening the delivery cycle. [0003] Inertial systems often require rapid system development delivery. The existing construction method first analyzes the product performance index, designs the system plan, selects the appropriate proc...

AI Technical Summary

Problems solved by technology

[0004] 1) The process is time-consuming, and the development cycle may exceed the short time limit required by the market

[0005] 2) If a problem is found during the debugging process, the hardware fault cannot be quickly identified, and it takes a lot of time and effort to troubleshoot the fault

If it is a hardware failure, it is necessary to take measures such as remaking the PCB board and re-debugging the program, which is time-consuming and laborious

[0006] 3) If the product requirements change, the design plan will start from scratch, and the development cycle will be further lengthened
