Following constantly development of informationization level, the aircraft flying control missions will happen remarkably changes, so the control system will adopt the united flying control pattern based on autonomous sensor information and co-information. This paper introduces one kind of hardware-in-the-loop simulation system of informationization flying control. The developing requirements about...
As the core device of Aircraft Control System, under the severe environment full of EMP, flight control computer would occur transient faults by interference of EMP, even cause mission failure. It's essential for a flight control computer in designing damage mode test software of EMP, locating faults, registering and analyzing fault information. This paper will introduce test flow and test scheme,...
Based on the PC/104 embedded computer the real-time data acquisition system, Made of a high-accuracy two-channels antennas tracking servo system, the principle, constitution, design characteristic and realization of full digital interface design are analyzed, Using Linux system, software is develop easily, so it has great facility and efficiency. Results show that this system meets the engineering...
The e-government system uses computer software and network technology to manage and maintain daily office, XML technology enables cross platform and programming language to exchange information, the combination of e-government and XML promotes e-government system's function to improve and technology to innovate. In this paper, we research e-government system for university on XML, introduce E-government...
A new applicable configuration method was studied to maintain the integrity and consistency of software products during software project development. During the study, configuration identification, change control, configuration status report and configuration audit were regarded as the emphasis that were studied with some actual project cases, combined theories with practice together. By the research,...
Research is held on risk management methods of software organization and the whole risk management process from the risk identification, the risk estimate and the risk response to the risk control of software projects. In terms of theory, a suit of risk management method system of software projects are put forwarded, which combines project management theory with the feature of software itself; in...
In pervasive computing, the computer is no longer a single computing device, but an information device with the embedded processor, memory, communication module and various sensors together. Combining with the pervasive computing and flight maneuvering characteristic, this article puts forward the simulation software of moving object midcourse mission change based on pervasive computing and relevant...
In order to assure the quality of software maintainability evaluation, setting up a reasonable index system and distribute the index weights with reason is the most important thing. In this situation, this paper set up an index system of software maintainability evaluation firstly, based on two principles such as giving prominence to main indexes and that indexes are usually required be measurable...
Based on the LabVIEW software and EST (error separation technology), virtual instrument is built for measuring machine tool guide way straightness. The general structure and measure principle are presented. Then, it discusses the realizing method of system hardware and software module in detail. It can acquire and treat data, save data, dynamically show the results of measurement and curve fitting...
To estimate software effort according to software size, statistical analysis was held using the historical project data. The tool statistics method and the programming statistics method were adopted independently for linearity regression analysis. After the regression analysis, the linearity regression equation was obtained. The final studies showed that the outcomes obtained by these two methods...
To ensure the estimation accuracy of software project schedule and improve the timely completion of the projects, a quantitative estimation guide of software project was studied combined with some actual project cases. A non-linear regression curve was obtained by the use of statistical analysis methods, on base of this a schedule estimation guide model was built and the use of the model was studied...
