Research And Application Of Software Reliability Designing

At present, the Railway Signal Monitoring System now has encountered some problems as follows: long development cycle,high cost, the lower of system performance, reliability and stability, the difficult of testing and maintenance and so on, we analysis these problems of the system in this paper. combining with the actual needs of the system, the paper put forward the reliability design methods of component technology base on the traditional reliability design method. The component model of the monitoring system is defined as the system component level, the component-General and the special components,and the system is divided into the Server-side program,the Local stations and the Terminals process procedures in three parts. According the functions and characteristics of the various parts, analysis and design the system architecture combinating the component technology, in the design process reflects the advantages of the reliability design methods which component-based technology prefer to the traditional technology, which greatly enhances the reliability of the system.
