Abstract

Abstract: This paper introduces the design and implementation scheme of a CTC system with safety functions. The CTC system identifies system safety functions through system risk analysis. Through the comprehensive application of system structure design, software security protection, system interaction mechanism design, and other security measures, the CTC system safety functions meet the SIL2 requirements and meet the design requirements of CTC systems with safety functions. The CTC system with safety functions has been applied in practical projects, and the next development direction is also proposed in this paper.

Key words: safety functions, CTC, risk analysis
