Abstract The railway computer interlocking system monitors the relevant equipment of the route in real time and completes the route control, which is the premise of the technical operation automation of the station train. In order to ensure the safety and reliability of the computer interlocking system, the station interlocking system is modeled based on the object-oriented idea, and then the instantiation of route control is realized. First of all, based on object-oriented technology, this paper analyzes the attribute of station interlocking equipment and system operation mechanism. On this basis, the route requirements of different station technical operations are analyzed, and UML is used to describe the key station interlocking equipment, the interlocking relationship between the equipment, the logic of station route control service, and the matching relationship with the route. Finally, Python language is used to realize the key service that automate the station route control to meet the goal of computer interlocking automation such as status of station equipment, service constraints and efficiency requirements.
