Communication-based interconnected and intercommunicated I-CBIT train operation control system

Abstract

The invention discloses a communication-based interconnected I-CBTC train operation control system, which is a mobile block safety control system that uses wireless communication to realize information transmission between the ground control center and the train, and the ATS or CTC is automatically supervised by the ground train System, database storage unit DSU system, computer interlocking CI system, ground area controller ZC or RBC system, vehicle controller VOBC system, double-ring redundant backbone network COM_network system, ground-vehicle redundant wireless network DCS system and network nodes The present invention standardizes and standardizes the functions, performance indicators and interfaces of the above systems. The beneficial effect of the invention is that users can purchase standard modular equipment from different suppliers, thereby providing a basis for interconnection and intercommunication for the construction and operation of the entire road network, and greatly reducing construction and operation costs.

Description

Technical field: [0001] The invention relates to a CBTC train operation control system based on wireless communication, in particular to a general I-CBTC train operation control system which can realize interconnection and intercommunication. It belongs to the technical field of rail traffic signal safety control. Background technique: [0002] At present, the technical level of my country's rail transit safety control system cannot meet the needs of high-speed railways and high-density urban rail transit. The key technologies and integrated equipment of train operation control systems for railway high-speed passenger lines and urban rail transit mainly rely on the introduction. For general rail transit lines, the safety guarantee system to ensure driving safety and improve transportation efficiency is based on the operation and control system of the track circuit. The shortcomings of small, one-way transmission and relatively large external interference, under the developm...

AI Technical Summary

Problems solved by technology

These manufacturers will automatically supervise the ground train ATS or CTC system, database storage unit DSU system, computer interlocking CI system, ground area controller ZC or RBC system, on-board controller VOBC system, double-ring redundant backbone network COM_network system and ground-car The composition of the redundant wireless network DCS system is regarded as a complete and inseparable system, and a complete system has been recommended to users on the grounds of meeting the safety certification requirements, which will bring huge psychological and economic burdens to users, and can only be used The complete systems of these manufacturers, and the implementation methods and approaches of these imported CBTC systems are different, and they cannot be interchangeable and universal between systems, resulting in a variety of different CBTC systems in a city or a railway line. Construction and operation have brought great impacts, the biggest impact of which is the increase in construction and operation costs, and the inability to achieve interconnection and resource sharing within the road network
