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

Abstract

The disclosed I-CBTC mobile closed train operation control system applies wireless communication way to transmit information between ground control center and train, and comprises an ATS or CTC system, a DSU system, a CI system, a ZC or RBC system, a VOBC system, a dual-ring redundant backbone network COM_network system, a ground-train redundant wireless network DCS system, and interfaces among nodes. This invention normalizes and standardizes former function, performance index and interfaces, and reduces cost greatly.

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...
