Embodiment Construction
[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0026] At present, most of the low-density railways adopt the CTCS-0 system, which is a set of technical safety assurance system formed by the long-term development of the railway signal profession. It is composed of general locomotive signals and train operation monitoring and recording devices (LKJ). There are some potential safety hazards in the operation of LKJ equipment under the actual conditions of large-scale use of long locomotive roads, fr...

The invention discloses a train operation control system suitable for a low-density railway, the train operation control system is based on wireless communication and multi-source information fused location technique, the information like train positions between a train and the ground as well as between one train and another train, the speed of the train, the line data, the speed limit command istransmitted through the wireless communication of a multi-load channel, the location and the integrity checking are completed through a mobile unit, the train occupancy checking is finished through the collaboration of the mobile unit and ground equipment, the train autonomously calculates, moves, authorizes, and automatically drives, and the low-cost safe reliable efficient train operation control system suitable for the low-density railway is achieved.
Description
technical field [0001] The invention relates to the technical field of rail transportation, in particular to a train operation control system suitable for low-density railways. Background technique [0002] The wide-area low-density railway network built in western my country and remote areas to serve national defense functions and coordinate regional economic development presents normal low-intensity, short-term high-intensity, high-impact transport capacity demand in special periods, and poor accessibility of maintenance personnel in alpine regions A train operation control system that is safe, reliable, low in construction and maintenance costs, and able to meet dynamic transportation needs is required. [0003] At present, the China Train Operation Control System (CTCS) is based on the actual operation of China's railways, and meets the technical specifications of the transportation needs of different lines in a hierarchical manner, and improves the efficiency of railway ...
