Abstract

The invention discloses a miniaturized test device for a rocket-borne computer, which comprises a main control module, an interface module and a power supply module, wherein the main control module adopts a ZYNQ series SOC to serve as a main control chip, an ARM is responsible for state control and data processing and display of the test, and an FPGA is responsible for generating a real-time signal for the outside world and collecting an external real-time signal; the interface module is used for realizing A / D (Analog-to-Digital) conversion, D / A (Digital-to-Analog) conversion, level conversion, analog signal filtering and the like; and the power supply module is used for providing a required power supply for test equipment and a tested single machine on the rocket. The miniaturized test device can realize the portability of a ground test device, and can achieve a purpose of rapid testing.

Description

technical field [0001] The invention relates to the field of aerospace and electronic science and technology, and mainly relates to a miniaturized testing device for an arrow-borne computer. Background technique [0002] The ground test device of the KS-7B arrow-borne computer, as the core test equipment before the arrow machine leaves the factory and before the arrow is loaded, is mainly used for the function and accuracy test of the arrow machine, and provides a platform for debugging, testing and acceptance of the arrow machine. [0003] At present, the ground test equipment of KS-7B arrow-borne computer is DFS-4B simulation real-time processing system. DFS-4B is mainly composed of purchased industrial computer, interface board, serial board, etc., and the operating system is DOS system. It has the defects of large size, insufficient automation of software, and cumbersome operation. [0004] In order to realize the portability of the equipment, the ground test equipment ...
