Problems solved by technology

There is no information interaction between vehicles, and subsequent trains cannot directly obtain the real-time position and operation information of the train in front, and do not know the traffic situation ahead
When the ground equipment or the train-ground information transmission system fails, the safety of the train will be seriously threatened

Abstract

The invention discloses an automatic train sensing system based on UWB communication. The system comprises a ground center device which assists a train in obtaining communication train information, correctly builds train-train communication, automatically receives data to monitor and control operation of the train, and helps a dispatching worker to manage the train, a train-mounted device which isdeployed on the train system and a track system thereof and used for collecting train sensing information at least comprising the train position, speed and train number, a sensor for transmitting thetrain sensing information through UWB communication, a trackside device and a distributed target controller communication network based on UWB communication. A majority of train control core functions are transferred to the train, the train-ground interaction information amount is decreased, the interaction time is shortened, and the whole system performance is improved, so that the train operation safety is better ensured, the transport capability is further improved, and the cost of the full life circle is effectively lowered.

Description

technical field [0001] The invention relates to the technical field of automatic train perception, in particular to an automatic train perception system based on UWB communication. Background technique [0002] The train operation control system is one of the important components of the railway signal system. It is composed of ground equipment and on-board equipment. It is used to control the train running speed, ensure the safe and efficient operation of the train, and is the brain and nerve center of the railway transportation system. [0003] The inefficient hardware performance of ultra-wideband (UWB), but the software richness that drives the hardware. Software improvement includes embedded software (the basic functions of UWB technology can be adjusted here) and API interface (upper-layer software can be added on this basis). [0004] In the past few decades, train operation control technology has mainly solved the problems of safety and automation. Although the spec...
