Abstract

The invention discloses a response positioning system suitable for a shunting locomotive. The response positioning system comprises a vehicle-mounted query host, a vehicle-mounted antenna and a ground transponder, wherein the vehicle-mounted query host sends carrier energy to the point transponder through the vehicle-mounted antenna to trigger the ground transponder to work; the ground transponder works to read pre-stored message data for PSK phase modulation and then sends the pre-stored message data outwards; and the vehicle-mounted query host receives the modulated message data through the vehicle-mounted antenna, decodes and restores the message data in a PSK mode, and sends the message data to the vehicle-mounted STP control system after verification. According to the system, a low-frequency-band wireless radio frequency technology is used for an on-site low-speed environment of rail shunting, data are wirelessly transmitted in a PSK phase modulation mode, the anti-interference performance is improved, phase changes can also be used as timing information to synchronize clocks of a transmitter and a receiver, and the transmission rate is doubled.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a response positioning system suitable for shunting locomotives. Background technique [0002] With the development of information construction of railway marshalling yards, real-time tracking and positioning of shunting locomotives in marshalling yards can not only provide support for marshalling yard dispatching decision-making management, but also provide safety protection information for on-site construction workers. The current positioning technology of railway rolling stock mainly includes positioning technology based on global GPS or Beidou system communication satellites, positioning technology based on line electronic tags and locomotive readers, positioning technology based on ground transponders and locomotive readers, etc. [0003] The positioning technology based on ground transponder and locomotive reader is an automatic identification technology based o...
