Abstract: A computer-based interlocking system is one pair of train travel system to provide safe conditions for the system, the station interlock system is to ensure that the station traffic safety and improve transport efficiency of a typical safety-critical system. In this paper, based on the formal method Event-B, it introduces the role of Agent interlock system specification defines, through modeling and verifying agent and Event-B, it constructs the station interlocking route control logic formal verification model, and conducts a formal specification and reasoning, the model is verified on the RODIN platform, validating by example, it meets the security needs of computer interlocking system.
