Abstract

The invention provides a train active safety protection system based on ultra-wideband technology. The train active safety protection system based on the ultra-wideband technology comprises two trainvehicle-mounted devices, a UWB device, a microcomputer interlocking monitoring system and a ground monitoring center. The two train vehicle-mounted devices are separately arranged at the front and rear ends of the train, the train vehicle-mounted devices comprise positioning units, vehicle-mounted hosts and train controllers. The positioning units are used for positioning the train and communicating, and the vehicle-mounted hosts are used for monitoring the real-time accurate distance between the train and other vehicles and between the train and a ground fixed node device. The UWB device is connected to the train vehicle-mounted devices for communicating with the train through UWB signals and measuring distance through a TW-ToF mode and outputting distance data with the train. The UWB device is further connected to the ground monitoring center for data transmission. The ground monitoring center comprises a monitoring center server for generating accurate position data of train according to the distance data output by the UWB device.

Description

technical field [0001] The invention relates to the technical field of protection systems, in particular to an active safety protection system for trains based on ultra-wideband technology. Background technique [0002] At present, on the closed subway tunnel line, it is almost impossible to use Beidou or GPS satellite positioning technology to achieve accurate point positioning of the train in the tunnel due to the line occlusion verification to realize the transmission and acquisition of satellite signals. Moreover, due to the inability to accurately locate the train, the train cannot be actively protected effectively, resulting in the inability to ensure the safety of the train. [0003] UWB (Ultra Wide Band) technology is a new communication technology that is very different from traditional communication technology. It does not need to use the carrier wave in the traditional communication system. It can transmit data with extremely narrow pulses below the order of magn...
