| The space computer is the satellite important component, guaranteed that the satellite completes each function normally, satisfies the directional precision, the stability and the satellite performance index; Along with astronautics science's and technology's development, the function which our country satellite realizes strengthens year by year, the space computer software accounts for the proportion also year by year to increase, more and more formerly the function which realizes by the hardware now realized by the software; Software's reliability and toughness direct relation entire star reliability and satellite lifetime. Along with test item's increase, the test request's enhancement, the space software simulation which formerly once established tests the platform to be unable to satisfy completely requests, to cause aspect and so on performance, intensity, security tests to be more effective, hardware fault's simulation is more real, proposed that the establishment mainly faces m1750 CPU based on hardware-in-the-loop the space software testing platform.This article first introduced that tests the platform construction method based on hardware-in-the-loop in the domestic and foreign development present situation, regarding this constructs the method principle with to realize the method to carry on the outline description; Then to this project's demand analysis, platform project design, platform contents and so on software and hardware design carries on detail introduced in detail that carries on to the use key technologies and the principle introduced with emphasis.This system uses testing tool ADS2 (Avionics Development System - 2nd Generation) is one kind specially for the aerospace application procedure test, the synthesis and the duty confirmed designs a section of real-time test and the simulation environment, are based on the hardware-in-the-loop simulation software confirmation equipment. The ADS2 system ensemble test facility proposed in view of the traditional method many integrated plans, under the usual user interface, may carry on the data analysis, the simulation, the drive, these model's I/O interface type is: ARINC429, ARINC629, MIL-STD-1553A/B, serial main line RS the 232/422/423/485, CAN main line, Synchro + Resolver I/O, LVDT + RVDT I/O, the IRIG time asynchronous, digital I/O and simulates I/O. It uses the general industrial standard for the foundation distributional real time system, this article introduced in detail it realizes the principle and the application example.This article will introduce that the structure and performance test tool Systemverify, this testing tool realizes the online program run coverage fraction and performance information gathering and the statistics, this article introduced this tool and produces in this system application effect.This article to uses the test system which the ADS2 real-time emulation tool realizes to carry on the explanation, including the frame design, introduced hardware interface's simulation, the software and hardware connection's simulation, introduced with emphasis, in the system realizes in the process difficulty and the key point. This platform present has realized to many software's dynamic simulation tests, completes confirmation test contents and so on software's function, performance, security, intensity. |
