Performance evaluation of railway computer interlocking system based on queuing theory
Proceedings of the 8th International Scientific and Practical Conference of Students, Post-graduates and Young Scientists. Modern Technique and Technologies. MTT'2002 (Cat. No.02EX550), 2004Microcomputer system is a large scale computer controlling system with the high demanding of real-time performance. We present two models based on the theory of random service to analyze the real-time performance of computer interlocking system. From analysis and comparison of the two models, we proposed the method to evaluate the real-time performance

Automatic Test Generation of Large Boolean Expressions in Computer Based Interlocking System
2017 24th Asia-Pacific Software Engineering Conference (APSEC), 2017Interlocking system is an important module to ensure traffic safety. However it is still very difficult to apply automatic testing in industrial application. In this paper, we propose an approach to generate test case automatically with the help of SMT Solver.

Study on the Design of Computer Interlocking System Security's Reliability
Applied Mechanics and Materials, 2013The reliability of computer interlocking system security has a close tie with many aspects such as the data information transmission accuracy of the entire system. If the reliability of the system security is not high, security-related accidents will be very easily caused in enterprises and bring about huge losses to enterprises, so study on the design

Research and Design of the New Network Computer Interlocking Simulation System
2016 Eighth International Conference on Measuring Technology and Mechatronics Automation (ICMTMA), 2016The traditional pure software emulation mode and sandbox mode simulation systems can only analog computer interlock operation, lacking simulation of field devices, and cost a lot in installation and maintenance. To solve this problem, we introduce a new network computer interlocking simulation system, which is designed based on B/S mode, ASP.NET and ...
