A method and system for processing ctcs-1 wireless data

Abstract

The invention belongs to the technical field of train control, and in particular relates to a method and system for processing CTCS‑1 wireless data. In the method of the present invention, the route data used by the vehicle-mounted equipment host is automatically generated from the ground equipment, and there is no need to manually compile the route data for each train's vehicle-mounted equipment, and the driver does not need to perform additional operations to select route information. The route data used by the CTCS‑0 vehicle-mounted equipment of the existing normal-speed lines needs to be written into the memory card in advance, and at the same time, it is necessary to assist the driver in some operations such as selecting the route number to control the train operation. The vehicle-mounted equipment can only Auxiliary train operation equipment cannot be used as defects such as driving certificates. Moreover, the present invention eliminates the maintenance work of compiling a large amount of line data for each vehicle-mounted device, and the host of the vehicle-mounted device combines the ground track circuit code and incoming route data to eliminate the risk of the vehicle-mounted device misusing the line data.

Description

technical field [0001] The invention belongs to the technical field of train control, and in particular relates to a method and system for processing CTCS-1 wireless data. Background technique [0002] China's normal-speed railways mainly use CTCS-0 train control system. The on-board equipment of CTCS-0 train control system is composed of general locomotive signal and train operation monitoring and recording device (LKJ). The on-board equipment reads the track circuit information on the ground and requires In advance, write all the line data information of the train running cross-roads for a certain vehicle-mounted device into the memory card and insert it into the vehicle-mounted device, and at the same time assist the driver to select the route number and other operations to control the train operation. At present, there are more than 20,000 general-speed railway vehicles in the country. The on-board equipment cannot be used as a safe driving certificate, and the compilati...

Problems solved by technology

At present, there are more than 20,000 general-speed railway vehicles in the country. The on-board equipment cannot be used as a safe driving certificate, and the workload of compiling the data for each locomotive’s on-board equipment is heavy, difficult to maintain, and easy to introduce safety risks.

[0003] In order to improve the usability and safety of the train control system on normal-speed lines, in the CTCS-1 train control system applied to normal-speed railways, in the existing CTCS-1 train control system, the ground equipment uses wireless communication to The vehicle-mounted equipment performs one-way broadcast communication. If the wireless transmission unit of the vehicle-mounted equipment receives and stores the route data and there is a wireless interruption, the wireless transmission unit fails and other abnormalities, the vehicle-mounted device cannot obtain the latest information after the train route changes. Line data, at this time, the on-board equipment still uses the line data stored before the route change according to the received transponder number, and the on-board equipment will misuse the ground line data, resulting in safety risks
