基于UPPAAL的二乘二取二逻辑建模与仿真
Logical Modeling and Simulation of Double 2-vote-2 Redundant Structure Based on UPPAAL
摘要
Abstract
Double 2-vote-2 redundant structure of high security and reliability is widely used in such security-intensive fields as nuclear power, aerospace and railway. To verify double 2-vote-2 redundant structure's core logic and guarantee its high security and reliability, this paper establishes and verifies double 2-vote-2 redundant structure models. Based on timed automata theory, train control system vehicle-mounted ATP subsystem's double 2-vote-2 redundant logic and the analysis of its working principles,this paper employs UPPAAL tool to build double 2-vote-2 redundant logical timed automata models and verifies respectively two-by-two and two-vote-two logical basic security properties. Redundant logical simulation is conducted by means of verified logical models. The results of modeling and program simulation show that vehicle-mounted ATP double 2-vote-2 redundant logical structure is safe and reliable.关键词
