Abstract

The invention discloses a rocket-board computer dynamic character test method and system for controlling signal digital transmission, using a 1553B bus message to perform signal digital transmission. The method comprises: 1) according to a configuration file and a configuration parameter, obtaining various parameters comprising an input frequency feature point parameter, and an output result determination standard parameter; 2) according to the set input parameter, initiating an operation mode of a dynamic characteristics test system; 3) automatically generating input excitation for a tested object in a test item; 4) executing the dynamic characteristics test that is based on frequency feature point, backstoping an output result and storing a display; and 5) computing a deviation between the output result and a theoretical result, automatically determining whether the test result meets a requirement of a standard criteria, and obtaining a test result. The present invention provides a system for completing the method. According to the present invention, the method solves a problem of digital test of the dynamic character of the rocket-board computer in a rocke lanucher controlling system, and achieves construction application effects of digitization, automation and intelligentization of the dynamic character test.

Description

technical field [0001] The invention relates to a method for testing the dynamic characteristics of an rocket-borne computer using a 1553B bus to transmit control signal data, and belongs to the technical field of test and test of launch vehicle control systems. Background technique [0002] The MIL-STD-1553B bus is a military bus standard for the integration of aircraft internal electronic systems, and is widely used in the aviation industry. Due to its high reliability, good real-time performance, and strong flexibility, the 1553B bus has been gradually used in systems such as launch vehicles, space shuttles, satellites, space stations, and aircrafts that require high reliability. [0003] The rocket-borne computer is the key single machine of the launch vehicle, and its dynamic characteristics are the key indicators of its applicability to the application environment. In the traditional dynamic test method, the excitation signal is input by the equipment instrument, and ...
