Embodiment Construction

[0020] The preferred examples will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0021] The basic principle of train monitoring is to use the train control system to calculate the allowable speed of the train in real time and generate a monitoring curve during the running of the train. Speed, the train is safe; otherwise, when the actual running speed of the train is greater than the allowable speed, the train control system will output braking. When calculating the allowable speed and generating the monitoring curve, four types of data are needed: driving permit information, line description information, temporary speed limit data and train parameters (train load, length, braking rate, etc.). Because the train data is fixed for each train and does not need data fusion, while others need to be provid...

Abstract

The invention discloses a method for improving the safety of a CTCS-3 (Chinese train control system-3) train control system in the technical field of railway safety running control. The method comprises line description information fusion, driving license information fusion and temporary speed limitation data fusion, wherein the line description information fusion is as follows: the comparison of line description information received by a CTCS-2 and a CTCS-3 is performed, if the results are consistent, the allowable speed is calculated directly, otherwise, the allowable speed is calculated by safety data; the driving license information fusion is as follows: when the range of a driving license of the CTCS-3 is larger than 7 rail circuit sections and the CTCS-2 gives out an upper limit of idle rail circuit sections, the allowable speed is calculated according to the driving license; and the temporary speed limitation data fusion is as follows: temporary speed limitation messages received by the CTCS-2 and the CTCS-3 are compared, if the results are consistent, the allowable speed is calculated directly, otherwise, the allowable speed is calculated by favorable data. With the adoption of the method, the accuracy and the credibility of the calculation results can be improved, thereby being conductive to safety running of trains.

Description

technical field [0001] The invention belongs to the technical field of railway safety operation control, and in particular relates to a method for improving the safety of a CTCS-3 train control system. Background technique [0002] With the opening of the Beijing-Tianjin Passenger Dedicated Line on August 1, 2008, in just two years, a number of passenger dedicated lines with a speed of more than 300km / h have been put into operation one after another in China, which marks that my country has entered the stage of becoming a high-speed train power. ranks. In order to meet the needs of the development of high-speed trains, my country has formulated the "China Train Control System CTCS (Chinese Train Control System) Development Plan", combined with the current situation of China's train control and future development needs, the Chinese train control system is divided into CTCS-0 to CTCS- 4 five levels. Among them, CTCS-2 is suitable for controlling trains with a speed of 200km / h ...
