基于STAMP与组合测试的城轨全自动运行系统车载设备安全测试方法研究
Research on the Safety Testing Method of Onboard Equipment of Urban Rail Transit Fully Automatic Operation System Based on STAMP and Combinatorial Testing
摘要
Abstract
Insufficient safety requirements and the large scale of test cases are the two main problems facing the on-board equipment testing process of the fully automatic operation system.This thesis proposes a security test method based on system-theoretic accident modeling and process theory and combinatorial test for the on-board equipment of the fully automatic operation system.First of all,based on the system-theoretic accident modeling and process theory,a layered control structure model on the on-board equipment is established,security constraints from the perspective of measurement is extracted,and the safety testing characteristics covered by security constraints are analyzed.Then,based on the best coverage of array and seed test cases and combined with security constraints,the genetic algorithm is used to reconstruct the optimal coverage number,and expand the streamlined test cases that meet the constraints.Finally,the fully automatic operation system platform departure scene is taken as an example to verify the effectiveness of the test algorithm of the vehicle equipment.The results show that in the case of the same combined coverage intensity,the test cases in the method proposed in this thesis are reduced by 16.45%than the test cases generated by the existing mainstream methods,which has certain practical significance for reducing the cost of vehicle equipment testing and improving the test efficiency.关键词
