[0004] Therefore, in order to realize the automatic control of the train control system, it is inseparable from the communication between the ground transponder and the on-board receiving equipment. It is too small to meet the needs, which may affect whether the train control system can safely, reliably and accurately control the train, and further affect driving safety

The invention discloses a frequency division multi-channel capacity multiplication type ground transponder and relates to the field of railway traffic safety. The ground transponder comprises original communication channels in the existing ground transponder and at least one newly added communication channel which is used for transmitting data required for train control to vehicle receiving equipment to improve the data capacity of the ground transponder, so that the data volume between the ground transponder and the train receiving equipment is doubled. The communication channel is newly added in the frequency division multi-channel capacity multiplication type ground transponder, the plurality of the communication channels which are in parallel connection operate independently, the data volume of the ground transponder can be enlarged, and the transmission rate of the newly added communication channel in the ground transponder is greatly improved simultaneously, therefore the communication data volume between the ground transponder and the vehicle receiving equipment is further improved, safe, reliable and accurate train control of a train control system can be guaranteed, and traffic safety is further guaranteed.
Description
technical field [0001] The invention relates to railway driving safety, is applicable to the field of train automatic control, and particularly relates to a frequency-division multi-channel capacity multiplication type ground transponder. [0002] Background technique [0003] At present, the basic method of controlling trains in my country's high-speed railways is to adopt "European" transponder technology. The brief principle of this technology is: all kinds of line data on the ground are stored by the ground transponder, such as line length, slope, curve, kilometer mark, commutation point, etc. When the train enters the action area of the ground transponder, The train radiates 27MHz energy to the ground. After the ground transponder receives the energy, it immediately transmits the line data stored on the ground to the locomotive by means of FSK frequency modulation with a carrier frequency of 4.23M. After the train receives the information on the ground, it is amplif...
