Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be pointed out that those skilled in the art can make some modifications and improvements without departing from the inventive concept, and these all belong to the protection scope of the present invention.

[0019] In the existing transponder system, LEU power amplifiers and active transponders form a transmission system, such as figure 2 As shown, to realize the function of transparently transmitting the data information sent by LEU to the on-board equipment through the transponder. At the same time, LEU can also detect the cable connection status before the two, and output an abnormal status signal when the cable status is abnormal.

[0020] In the design of the present invention, LEU power amplifier, relay ...

Abstract

The long-distance transponder information transmission system of the present invention includes a LEU power amplifier, a relay unit, and an active transponder, wherein the LEU power is placed in the mechanical room, connected to the input port of the relay unit through a transmission cable, and the output port of the relay unit Connect to the active transponder installed in the middle of the track through a transmission cable; in addition to the output function of the standard C interface data, the LEU power amplifier superimposes the DC level signal output on the C interface signal; the transmission system can realize transponder information transmission The extension of the distance can realize the transparent transmission of data at least 5000 meters. The technical advantages of this application are as follows: to realize the extension of transponder information transmission distance, the cost of relay unit is greatly reduced compared with the scheme of arranging trackside LEU, and the cables used are all special cables used in the existing transponder transmission system .

Description

technical field [0001] The invention relates to a transponder information transmission relay module and a ground electronic unit. Background technique [0002] Currently on the market, the transmission distance between the ground electronic unit (hereinafter referred to as LEU) and the active transponder does not exceed 2500 meters, such as figure 2 shown. As a part of the balise transmission system, LEU is installed in the mechanical room of the station, and sends corresponding message data to the trackside active balise through the C interface. Restricted by electrical performance, industry standards require that the C-interface transmission distance between the LEU and the active transponder be 2500 meters. [0003] When faced with the application requirements of a transmission distance exceeding 2500 meters, the LEU is usually placed on the trackside for outdoor installation to shorten the distance between the LEU and the transponder. [0004] But this solution has ma...
