Rail transit train detection method and equipment

Abstract

The invention provides a rail transit train detecting method and device. The method includes the following steps that (1), a rail is divided into a plurality of sections; (2), a train sensor set is arranged at a port of each section; (3), according to train signals sensed by the train sensor sets, the operation direction and / or operation speed and / or behaviors of the train entering and exiting from each section are judged. The detecting device comprises train detecting units and primary processing units, wherein each train detecting unit is located in the range, with the capacity for inducing passing of the train, of the port of each section and used for detecting whether the train passes by or not, and the primary processing units correspond to the train detecting units one to one and are connected with the train detecting units in a communicated mode. The rail transit train detecting method and device can be suitable for a traditional steel wheel-steel rail transit system and particularly suitable for a rail transit system, wherein the rail transit system does not have steel wheel-steel rail characteristics, or extra detecting equipment can not be installed on steel wheels and steel rails of the rail transit system, and effectiveness, safety and reliability of operation control over the rail transit system are improved.

Description

technical field [0001] The invention belongs to the technical field of rail transit safety, and relates to a technology for detecting running information of rail transit trains. Background technique [0002] Train speed measurement and positioning and track section occupancy detection are one of the key technologies in the automatic control system of train operation. It is the basis for realizing train overspeed protection, train operation monitoring and automatic train driving. Its accuracy and reliability directly affect the safety of train operation. and operating efficiency. [0003] Low-speed maglev transportation is an ecologically pure, low-noise, and highly adaptable transportation mode, and its signal system is an important subsystem to ensure the safe operation of maglev trains. Since there is no steel wheel-rail in the maglev transportation system, the occupancy detection method of the traditional wheel-rail system is based on the characteristics of the steel whe...

Problems solved by technology

This kind of train speed measurement positioning and track section occupancy inspection scheme based on vehicle-mounted detectors and vehicle-ground communication systems has the following defects for rail traffic operation control systems that require high safety and reliability: Fault, the ground control center is difficult to judge the position of the train. According to the principle of failure-safety, the on-board control and protection system will unload the train when necessary, perform regular braking or emergency braking, and control the train to decelerate or stop

This will cause train delays, affect the efficiency of train operation, and seriously affect the safety of train operation, causing unnecessary losses

[0004] In addition, the modern tram system has a wide range of applications in Chinese cities. Although it is a wheel-rail transportation method, the traditional track circuit and axle counter are also not suitable for sharing ground road resources with urban vehicles. installed in the modern tram system, so it is also necessary to seek a non-contact train detection technology
