Optical fiber inertia unit automation testing system

Abstract

The invention discloses an optical fiber inertia unit automation testing system which comprises a programmable power supply and a PXI (Peripheral Component Interconnect) chassis, wherein the programmable power supply is connected with a controller by virtue of an internet access and is used for supplying power to an optical fiber inertia unit and monitoring a power output value in real time; the PXI chassis comprises an embedded master controller, a serial communication card, a multifunctional acquisition card, a bus card and a self-developed board card; and the self-developed board card is used for receiving and displaying ground test interface data and arrow interface data of the optical fiber inertia unit, transmitting telemetering request reception data to the optical fiber inertia unit, receiving and displaying the telemetering interface data of the optical fiber inertia unit and transmitting a take-off signal. According to the testing system disclosed by the invention, configuration of an automatic testing process is completed by utilizing a read-write configuration file; meanwhile, a highly cohesive and low coupling plug-in procedural framework is designed, the maintainability of software is improved, and function extension of test of other models is subsequently completed conveniently; and finally, high-speed data acquisition is realized by utilizing a multi-thread andtiming cycle mechanism.

Description

technical field [0001] The invention relates to an automatic test system for optical fiber inertial group, which belongs to the technical field of automatic test. Background technique [0002] In recent years, with the development of modern inertial technology, the strapdown inertial integrated navigation system has become one of the key equipment necessary for launch vehicles. As the core component of the system, the optical fiber inertial group is the core component of the system. important role. [0003] At present, the traditional optical fiber inertial group test equipment has a long development cycle and poor scalability. They are all customized designs based on specific inertial group models, and the reusability is poor. In addition, the test process needs to be completed manually, which is cumbersome to operate and has a low degree of automation. Not high, low test efficiency. Contents of the invention [0004] Purpose: In order to overcome the deficiencies in th...
