Abstract

The invention discloses an automatic train driving system based on UWB communication and distance measurement. The automatic train driving system comprises a vehicle-mounted part and a ground part, wherein the vehicle-mounted part is arranged on a train system and a track system thereof and is used for acquiring train sensing information at least comprising train location, speed and train serial numbers, the train sensing information is transmitted by virtue of a UWB communication way, the ground part is used for assisting the train to acquire the communication train information, for performing the supervision and control and assisting the dispatching personnel to manage the train; the automatic train driving system also comprises a UWB distance measurement module which is used for measuring a distance between two trains and between the train and a station; the driving system comprises a judging module and a control module. When an automatic driving train has failure, the train can runto a close station to be repaired at a relatively low speed, so that the failure train is prevented from influencing the trains running normally on the whole line, and convenience is provided for themaintenance work of the maintenance personnel at the station.

Description

technical field [0001] The invention relates to the technical field of signal control, in particular to an automatic train driving system based on UWB communication and distance measurement. Background technique [0002] With the rapid development of urban rail transit, higher requirements are put forward for the safety and automation of the entire train control system while operating efficiently. Compared with the manual driving system and the subsequent semi-automatic driving system, the fully automatic driving system effectively reduces the adverse effects caused by human errors, improves operational efficiency, and reduces operating costs. It is the development trend of urban rail transit control systems. [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 softwa...
