Embodiment Construction

[0030] The virtual block system based on wireless locomotive signal is characterized in that the system uses wireless locomotive signal equipment to transmit locomotive signal and other train control information, uses satellite positioning and odometer combination technology to realize train positioning, and uses train tail device and positioning information to determine the integrity of the train , using the virtual blocking machine to complete the virtual blocking. The system includes vehicle equipment, ground equipment and wireless communication equipment. The basic structure of the system is shown in Figure 1.

[0031] The on-board equipment includes wireless locomotive signal on-board equipment, train operation monitoring device (ATP or LKJ2000), man-machine interface (DMI), recording unit, train brake interface unit, GPS module, train tail device locomotive equipment, etc. The wireless locomotive signal on-board equipment is respectively connected with the train operati...

Description

technical field [0001] The invention relates to a virtual blocking method for railway traffic, in particular to a virtual blocking train control system based on wireless locomotive signals. The invention belongs to the technical field of railway signals. Background technique [0002] With the implementation of the railway leap-forward development strategy, China's railways have undergone rapid changes. After the five major speed increases, the sixth speed increase will be carried out soon. The EMU with a train running speed of 200Km / h will adopt the CTCS2 train control system. The construction of the Beijing-Tianjin high-speed railway has started, and more than 10,000 kilometers of dedicated passenger lines will be built in the Eleventh Five-Year Plan. There are also some uncoordinated or relatively lagging problems in the development process. There are more than 30,000 kilometers of semi-automatic block lines in my country's existing lines. Due to the outdated block equip...
