Embodiment Construction

[0015] In order to clearly illustrate the device of the present invention, preferred embodiments are given below and described in detail in conjunction with the accompanying drawings.

[0016] see figure 1 , an isolation adjustment module and a pulse track circuit receiver receiving an asymmetric pulse signal, the isolation adjustment module outputs the asymmetric pulse signal to the pulse track circuit receiver through a single coil as a whole, and the pulse track circuit receiver discriminates The asymmetrical pulse signal triggers the track relay, or sends the discriminated result to an interlocking system or a signal control system, and the signal control system is a signal control system such as a train.

[0017] Wherein, the signals input and output by the isolation adjustment module are all asymmetrical pulse overall signals. The structure diagram of the pulse track circuit receiver with A / D module can be found in figure 2 ,include:

[0018] The A / D module is used t...

Abstract

The invention discloses a single-coil pulse track circuit receiving device including an isolation and adjustment module and a pulse track circuit receiver for receiving asymmetric pulse signals. The isolation and adjustment module outputs the asymmetric pulse signals to the pulse track circuit receiver through the integer of a single coil; the pulse track circuit receiver distinguishes the asymmetric pulse signals and triggers a track relay, or sends the distinguished results to a signal control system, such as interlock or train control, etc. The device can be applied to pulse track circuits of track sections of different traction types, such as electrization, non-electrization, etc., thereby avoiding faulty operation of the signal control system and ensuring safety in travelling.

Description

technical field [0001] The invention relates to the field of railway automation signal control, in particular to a single-coil pulse track circuit receiving device. Background technique [0002] In 1984, the high-voltage asymmetric pulse track circuit passed the technical appraisal of the Ministry of Railways, and its receiving device was composed of "decoder and binary differential relay". The decoder tracks out two sets of coils through the transformer, completes the adjustment of the peak and peak signals respectively, and drives the binary differential relay. The analysis and test show that: under the condition of symmetrical interference signal input, in the output circuit of the peak-tail coil, faults such as capacitor or diode element failure and poor contact of lead wires can change the symmetrical interference signal into an asymmetrical signal, resulting in wrong excitation of the differential relay , affecting the safety of railway transportation. [0003] In th...
