Abstract

The present invention provides a CTCS-3-based mobile block train control system (CTCS-3I) and method to solve the problem that high-speed trains cannot realize mobile block. The mobile block train control system is based on the existing CTCS-3 without adding hardware equipment. Through the control algorithm, the driver sends a registration application to the RBC before the train leaves the warehouse, and the train registration is completed after the train identification is completed; the train starts to run Finally, the hardware coordinates to complete the collection and transmission of train operation data, train integrity detection, calculation of target distance mode curve and generation of mobile authorization to realize mobile blocking. The present invention changes the target point of train tracking from the beginning of the existing track circuit to the tail of the forward train, shortens the train tracking interval, and improves the passing capacity of the train in the section by 50%; CTCS-3I is used in the train operation control process , increasing the parallel monitoring of train positioning, speed and tracking interval, improving the safety of train operation.

Description

technical field [0001] The invention belongs to the field of rail transit and intelligent transportation, and in particular relates to a CTCS-3-based mobile block train control method and system. Background technique [0002] Rail transit, including main line railways, high-speed railways and urban rail transit, has become the main means of transportation for people to travel and transport goods due to its advantages of large capacity, high speed, punctuality, convenience, safety and comfort, energy saving and environmental protection. Transportation capacity is a key indicator to measure the quality of rail transit. Typical methods to improve transportation capacity include increasing train speed, lengthening train formation, running heavy-duty trains, optimizing transportation plans, and strengthening transportation organization management and scheduling, etc. Among them, in terms of railway signals, there are many technologies to improve transportation capacity, such as ...
