To make the object, technical solutions and advantages of the present invention clearer clearly, with reference to embodiment and attached drawing pair
Technical solution in the embodiment of the present invention is described in further details.Obviously, described embodiment is the part of the present invention
Embodiment rather than whole embodiments.Here, the exemplary embodiment and its explanation of the present invention are mainly used for explaining this hair
It is bright but not as a limitation of the invention.
Transponder is a kind of point type ground communication facilities, is mounted on the railway roadbed among two rails, is used to implement ground
Communication between face and train.Common passive balise be mounted on rail among situation as shown in Figure 1a, each transponder
15 are fixedly mounted on single sleeper, and the length of transponder direction along ng a path (i.e. direction shown in arrow in Fig. 1 a) is about 245mm,
The horizontal force of direction along ng a path ranging from 500mm~600mm.The sphere of action disclosure satisfy that current train normally travel highest
The requirement of speed per hour 350km/h.
But train return library docking process in, from braking to stopping this period can move one section of braking distance.This section system
Dynamic distance would generally make train cross the sphere of action of transponder, cause train that can not receive response when needing restarting
The signal of device, so as to can not normally start.
The transponder of the extension sphere of action of the present invention extends reception antenna and transmitting antenna in the direction along track
Length increases horizontal force range.The reception antenna is receiving the energy for the 27MHz that train-installed equipment is sent out；Institute
Transmitting antenna is stated to transmit the message that transponder stores using the fsk signal of 4.23MHz as carrier frequency to train.The extension of the present invention
The scheme of one embodiment of the transponder of sphere of action is as follows：
Embodiment one：
A kind of transponder for extending sphere of action, including signal processing module, the first coaxial cable, housing.It is described coaxial
Cable as shown in Fig. 2, including from inside to outside successively it is parallel, coaxial arrangement the first core wire 9, the first insulation fill stratum 13, first
