A Track Circuit Electronic Receiver

Abstract

The invention provides an electronic receiver for a track circuit. The electronic receiver comprises at least one track signal acquisition unit, a digital signal processing unit and a communication unit, wherein the track signal acquisition unit comprises a track signal conditioning unit and a frequency and amplitude detection unit; the track signal conditioning unit comprises a first inductor, asecond inductor and a transformer; the input ends of the first inductor and the second inductor are connected with the output end of a track signal input protection unit; the output ends of the firstinductor and the second inductor are connected with the input end of the transformer; the output end of the transformer is connected with the frequency and amplitude detection unit; track signals aretransmitted to the frequency and amplitude detection unit for detecting frequency and amplitude after being isolated and boosted by the first inductor, the second inductor and the transformer. By utilizing the invention, the product cost performance is improved while the interface characteristics are satisfied.

Description

technical field [0001] The invention relates to the technical field of locomotive dispatching, in particular to an electronic receiver for track circuits. Background technique [0002] As a key device in the field of railway track circuits, phase-sensitive track circuits are used to detect the occupancy and idle status of rails. With the development of electronic technology, the phase-sensitive track circuit receiving device has been electronicized, completely replacing the old-fashioned binary two-position relay. [0003] At present, the widely used microelectronic receivers all use single-chip microcomputers to collect information, and use a separate track step-up transformer to boost the input signal to improve signal strength. Due to the large size of the step-up transformer, a separate module is required for installation, and space utilization The efficiency is low, the wiring is complicated, it is not conducive to on-site maintenance and installation, and the cost per...
