Vehicle-mounted non-contact transponder programming device and vehicle-mounted transponder programming method

Abstract

The invention discloses a vehicle-mounted non-contact transponder programming device and a vehicle-mounted transponder programming method. The device comprises a host unit and an antenna unit. The host unit is installed in a compartment, the antenna unit is installed outside the compartment, the host unit and the antenna unit are connected, the antenna unit is connected with a transponder through a wireless interface in an air gap, the host unit comprises a processing control unit, a comparison unit, a demodulating and decoding unit, a filtering unit, a message storage unit, a modulating unit, a power amplification unit and a power unit. The antenna unit comprises at least one of a 4.23 MHz antenna, a 9.032 MHz antenna and a 27.095 MHz antenna. The vehicle-mounted non-contact transponder programming device and the vehicle-mounted transponder programming method have the advantages that when a maintenance train with the vehicle-mounted non-contact transponder programming device passes a railway line, message programming work of all transponders installed on the line can be automatically finished, efficiency is high, and labor intensity is relieved; workers do not need to conduct message programming along the railway line, and potential safety hazards are eliminated.

Description

technical field [0001] The invention relates to a point transponder transmission system of a train operation control system in the field of railway communication signals, in particular to a vehicle-mounted non-contact transponder programming device and a programming method. Background technique [0002] The point transponder transmission system is widely used in high-speed railways and urban subways. It is an important solution for vehicle-ground communication to transmit ground information to vehicle control equipment. The ground information stored in the transponder needs to program the preset message into the transponder message memory in a wireless or wired way through message programming. At present, transponder message programming requires signal workers to carry portable programming equipment and walk along the railway line to program the transponders (also called ground transponders because they are installed on the ground in the track) one by one. The working enviro...
