基于可信性思想的实时测控软件系统开发方法

Development Method of Real-Time Measurement and Control System Based on Dependability

根据新形势下实时测控软件系统的要求,提出基于可信性思想的系统开发方法。从软件可信性的角度,探讨实时测控软件系统的开发方法,按照可信性要求制定出软件开发和测试规范,采取简化设计、容错设计与自启动技术、配置管理技术相结合的方法来确保软件可信性,并结合实例给出具体的设计方法和测试方案。结果表明:该方法能提高软件整体质量和开发速度,保证软件开发的可信性。

According to the requirement of real-time measurement and control system in new condition, this paper proposes the methods of system developing based on dependability. In the view of dependability, the developing methods of real-time measurement and control system are analyzed, the specification of software development and test are made in term of dependability, in detail, the technology of simple design, fault tolerant design and self-restart, configuration management are developed for assuring the dependability, a practical example for design and testing schemes are proposed. Results indicate that the methods introduced could enhance the quality of software and the speed of development, meanwhile assuring the dependability of software research and development.
