Abstract

The invention relates to a station coded transmitter. The station coded transmitter comprises a first channel, a second channel, a third channel and a logic control unit which are connected with one another, according to the invention, the first channel and the second channel respectively judge whether the acquisition of the channel signals received by themselves is correct or not and perform mutual correction; and the logic control unit controls the output of the coded signal according to the judgment result and the mutual correction result, so that the safe output of the coded transmitter isguaranteed, and the high-stability and high-precision coded signal can be transmitted to the track.

Description

technical field [0001] The invention relates to the field of track signal equipment, in particular to a station code transmitter. Background technique [0002] As a sending device, the coded transmitter is mainly used to send coded signals to the track. It is suitable for non-electrical and electrified section 2000 type non-insulated frequency shift automatic block and code system in the station. It is used for automatic block, locomotive signal and overspeed protection. . The stability and accuracy of the coded signal sent by the existing coded transmitter are poor, and the reliability is low, which brings safety risks to the personnel and equipment of the station. Contents of the invention [0003] In view of the above technical problems, the present invention provides a station telegraph transmitter. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a station code transmitter, comprising a first cha...
