Embodiment Construction

[0032] The present invention will be further described below in conjunction with accompanying drawing.

[0033] Such as figure 1 As shown, the scalable inertial platform circuit box automation test system based on the PXI bus is built on the PXI bus, and is composed of reasonable and efficient cooperation between various modules with clear functions and outstanding performance. The modules constituted are: a dynamic loop characteristic test module, a power supply program control module, a multi-channel acquisition module, a communication control analysis module, and a man-machine interface operation display module.

[0034] In view of the diversity of tested products, the test equipment uses the matrix switch control module on the PXI bus for the first time, which can perform the following operations: 1. The point number of the circuit box is connected to the matrix switch module, and the circuit connected to the matrix is ​​controlled by the power supply program control modul...

Abstract

The invention discloses an extensible platform circuit case automation testing system based on a PXI bus. The extensible platform circuit case automation testing system comprises a dynamic loop characteristic testing module, a power supply program control multipath acquisition module, a communication control parse module, and a human computer interface operation display module. The extensible platform circuit case automation testing system overcomes the disadvantages of low test efficiency and limited test precision due to hand-operated intervention of each point by an original inertia platform circuit case, the relatively independent functional module is used for completing the test tasks with a platform mode, the system has strong compatibility and expansion performance, can satisfy thetest requirement of the current circuit case and fully considers the expandability of a future product.

Description

technical field [0001] The invention relates to a test system of a platform circuit box, in particular to an automatic test system of an expandable platform circuit box based on the PXI bus. Background technique [0002] In the application field of platform inertial navigation systems, with the gradual increase in batch production of inertial devices, the test requirements for inertial platform circuit boxes are getting higher and higher, and the debugging cycle is getting shorter and shorter. The test requirements for various inertial platform circuit boxes are emerging in an endless stream. The real-time performance, compatibility and reliability of the data acquisition, storage and various signal processing inside the circuit box of the test system have put forward higher and higher requirements. And with the increasingly mature technology of fault self-detection and self-diagnosis, for the purpose of protecting the system and reducing system damage, the test system needs...
