Problems solved by technology

[0003] 1. Because the magnetic field distribution on the inner side of the rail is different from that on the outer side of the rail, the receiving voltage amplitudes of the two coils are different; 2. When the locomotive is running on a large curve, the receiving coil moves along with the locomotive, changing the center position of the coil. Deviation to one side, resulting in a large difference in the output amplitude of the two channels, unbalanced; 3. When there is interference in the external environment, the dry signal cannot be offset by itself, causing the normal signal to be interfered, causing the output waveform of the receiving coil to be chaotic, so that the host cannot Correctly identify and select the code, causing the locomotive signal to not work normally, and an error display appears

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 a series of locomotive signals, in particular to a receiving coil for receiving current signals on rails and converting them into voltage signals with the same frequency characteristics, which are used for code selection by a host computer. Background technique [0002] The currently used locomotive signal receiving coils all adopt a double-circuit structure wound at both ends of a single magnetic core. Each coil is used in series on the inside of the rail and one on the outside of the rail. The obvious disadvantages of this structure are: [0003] 1. Because the magnetic field distribution on the inner side of the rail is different from that on the outer side of the rail, the receiving voltage amplitudes of the two coils are different; 2. When the locomotive is running on a large curve, the receiving coil moves along with the locomotive, changing the center position of the coil. Deviation to one ...
