Automatic train protection system for monorail

Abstract

The invention discloses an automatic train protection system for a monorail, and relates to the technical field of train protection systems. A vehicular controller is respectively connected with a wireless communication terminal, a GPS (global positioning system), a human-computer interaction interface, a transponder transmission module, a speed sensor and a train connector unit, the vehicular controller comprises two sets of secure computer cases and one set of train connector case, the secure computers include an I-series secure computer and an II-series secure computer, and the secure computer cases form a 'square' structure capable of improving system availability. According to characteristics of a monorail train, the train is positioned by the ground in a non-contact manner, three-dimensional space positioning of the train is achieved, and safer and richer signal input and output interfaces greatly improve safety and expandability of the automatic train protection system and adapt to a monorail train system.

Description

technical field [0001] The invention relates to the technical field of train protection systems, in particular to an automatic train protection system suitable for monorails. Background technique [0002] The automatic train protection system mainly relies on external equipment, such as sensors, transponders and other external equipment to receive ground position, speed limit and other information, compare the ground information with the current information on the train, and control the train braking system according to the ground conditions to ensure train operation Safety. The existing automatic train protection system is mainly aimed at double-track lines such as large railways and subways. The train uses steel wheels, and the ground positioning is short-circuited through the contact between the steel wheels and the double-tracks to form a closed-loop track circuit. However, the monorail line cannot meet the basic conditions for the application of track circuits. The tra...

Problems solved by technology

However, the monorail line cannot meet the basic conditions for the application of track circuits. The train uses rubber tires that do not contact the track, and the monorail cannot form a closed loop. In terms of train positioning, the existing automatic train protection system uses a two-dimensional coordinate system to store relative coordinates on the ground and some The slope information of special points cannot meet the complex spatial change requirements of monorail lines (straddle or suspension); in terms of signal control, with the rapid development of sensor technology, the information that trains need to obtain and the equipment that needs to be controlled are becoming more and more Many, the existing signal input and output mechanisms are not very scalable, and can no longer meet the growing demand in terms of quantity and security
