Train signal system device and train distance-to-go detection method

Abstract

The invention discloses a train signal system device, which comprises a right-of-way signal chain end point setting unit, a right-of-way signal chain relay unit and a right-of-way signal chain detection unit, wherein the right-of-way signal chain end point setting unit is used for setting an end point position for a running train and transmitting a wireless right-of-way signal; the right-of-way signal chain relay unit is configured along a track for forwarding the wireless right-of-way signal, so that the wireless right-of-way signal forms a right-of-way signal chain containing distance-to-go information in front of the train; and the right-of-way signal chain detection unit enables the running train to realize receiving of information of the right-of-way signal chain and calculation of the front distance-to-go. A train distance-to-go detection method comprises the following steps of: transmitting the wireless right-of-way signal at a front station or a front train; forwarding the wireless right-of-way signal through the right-of-way signal chain relay unit which is configured along the track so as to form the right-of-way signal chain; receiving the wireless right-of-way signal at the rear train; and calculating the distance-to-go with the front station or the front train by the rear train according to the received wireless right-of-way signal. The train signal system enables the train to be safer.

Description

technical field [0001] The invention relates to a signal system device, in particular to a train dynamic signal system device and a train feasible distance detection method based on distance measurement of a passing signal chain. Background technique [0002] At present, the "blocking system" is basically used in rail transit to control the operation of trains, so as to effectively ensure that there is neither a preceding train nor a following train entering this section to collide with the train in its own blocking section (section). The train signaling system is a common means to realize said "blocking". The most commonly used blocking system for traditional railways is "Track Circuit Based Train Control" (Track Circuit Based Train Control, TBTC). "Communication Based Train Control (CBTC)" (Communication Based Train Control, CBTC), which makes train operation more reliable, flexible and operationally efficient. [0003] What TBTC and CBTC express is actually a method or ...

Problems solved by technology

This process is not only complicated, but also expensive. When the control center fails, the operation of the train will be terminated, or the manual operation mode without signal guarantee can only be used. In this case, the safety of the train operation is not guaranteed. , and in the event of signal system failure and human error, it may also cause serious train collision accidents
