Embodiment Construction

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] At present, fault monitoring is carried out by laying two alarm lines, and multiple light positions share a set of alarm lines, which has the problems of high construction complexity, high cost, and low fault location accuracy. Based on this, a railway signal machine fault monitoring system provided by the embodiment of the present invention can use power supply cables to tran...

Abstract

The invention provides a fault monitoring system for a railway signal machine, and relates to the technical field of railway signals. The fault monitoring system comprises an intelligent lighting unitand a machine room terminal; one end of the intelligent lighting unit is connected with a dual-filament bulb of the railway signal machine, and the other end of the intelligent lighting unit is connected with the machine room terminal through a power supply cable line of the railway signal machine; the intelligent lighting unit comprises a filament conversion relay, a signal transformer, a load switching relay and a resistive load; and the machine room terminal determines whether the railway signal machine is faulted or not by monitoring the current change on the power supply cable line and gives an alarm. Compared with the prior art, a special alarm line does not need to be laid on a railway site, fault positioning and alarming functions of the railway signal machine can be realized by using the existing power supply cable line, the construction complexity is lowered, the cost is saved, and the fault positioning precision is improved.

Description

technical field [0001] The invention relates to the technical field of railway signals, in particular to a railway signal machine failure monitoring system. Background technique [0002] The railway signal machine refers to the fixed signal machine on the railway that uses lights of different colors and quantities or the positions of arm panels of different colors and shapes to display command lines and shunting orders. It is one of the important components of the railway signal system. [0003] At present, the light source of the outdoor color light signal mechanism (railway signal machine) on the railway site is mainly a double-filament incandescent bulb, and its actual service life is only 2000-3000 hours. When the main wire of the bulb is broken and switched to the auxiliary wire, its service life is only 500 hours. At this time, the signal worker (staff) must be informed of the situation as soon as possible, and go to the corresponding railway signal light position to r...
