Series cab signal two-way receiver coil

Abstract

A series locomotive signal two-way receiving coil mainly comprises a balanced two-way receiving coil (1), a fiber glass reinforced plastics casing (2), a fine steel hanger (3) and a two-core shielded-cable lead (4); wherein, the permeable materials of different heights are adopted to form a main magnet core (11) and an assistant magnet core (12) which are bound together to form the balanced two-way receiving coil (1) and two groups of coils are arranged inside the fiber glass reinforced plastics casing (2) in parallel and screwed with the fine steel hanger (3) through a connector (33). The two-core shielded-cable lead (4) is respectively derived from the protective sleeve (32) of two groups of coils. The receiving coil is connected with a series locomotive by a connector (15) on the proper position. The coil has simple structure, low manufacturing cost and easy application and maintenance process.

Description

technical field [0001] The invention relates to a receiving coil for receiving signals from a series of locomotives, in particular to a receiving coil used for receiving current signals on rails and converting them into voltage signals with the same frequency characteristics, which are supplied to the host computer for code selection. Background technique [0002] The currently used locomotive signal receiving coils all adopt a double-circuit structure with a single magnetic core wound at both ends. Each coil is used in series on the inside of the rail and the other on the outside of the rail. The obvious disadvantages of this structure are: 1. Due to The magnetic field distribution on the inner side of the rail and the magnetic field distribution on the outer side of the rail are different in intensity, which makes the two coils receive different voltage amplitudes; 2. When the locomotive is running on a large curve, the receiving coil moves meanderingly with the locomotive,...

Problems solved by technology

[0002] The currently used locomotive signal receiving coils all adopt a double-circuit structure formed by winding both ends of a single magnetic core. One of each coil is used in series on the inside of the rail, and the other is used in series on the outside of the rail. The obvious disadvantages of this structure are: 1. The magnetic field distribution on the inner side of the rail is different from the magnetic field distribution on the outer side of the rail, so that the receiving voltage amplitudes of the two coils are different; 3. When there is interference in the external environment, the interference signal cannot be canceled by itself, causing the normal signal to be interfered, causing the output waveform of the receiving coil to be chaotic, and the host cannot correctly identify and select Code, causing the locomotive signal can not work normally, error display
