Abstract

The invention provides a moving block train control system (China train control system (CTCS)-3I) and method based on a CTCS-3. The moving block train control system and method are used for solving the problem that a high-speed train cannot realize moving block. According to the moving block train control system, hardware equipment is not additionally arranged on the basis of an existing CTCS-3, through a control algorithm, a driver sends application for registration to an RBC before the train is pulled out, and train registration is completed after train recognition is completed; and after the train starts operation, hardware coordinately completes collection and transmission of train operation data, train integrity detection, calculation of a target distance mode curve and moving authority generation, and moving block is realized. A target point of train tracking is changed from an existing track circuit starting end into the tail of the advancing train, the train tracking interval is shortened, and the passing ability of the train in a section is improved by 50%; and in the train operation control process, train positioning and parallel monitoring of the speed and the tracking interval are added by the CTCS-3I, and the safety of train operation is improved.

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 ...
