Intelligent uninterruptible monitoring system of LED light source of railway signal machine

Abstract

The invention relates to an intelligent uninterruptible monitoring system of the LED light source of a railway signal machine and belongs to the railway transportation technical field. A plurality of new technologies such as over-current protection, microprocessor control, numerical code display and sound-light alarm are adopted, and the uninterruptible monitoring problem of the LED light source of the railway signal machine under a condition that the signal machine is in a turned-off state in China can be solved. According to the intelligent uninterruptible monitoring system, an indoor circuit is installed in a square metal box with a shielding function; an outdoor circuit is installed in an engineering plastic box with a shielding layer; a light emitting and uninterruptible monitoring circuit is installed in an outdoor signal mechanism; a signal backup power supply is adopted, so that signal normal display is not affected; and the indoor circuit and the outdoor circuit are connected through a signal cable; and various technical indicators are in line with existing railway industry standards, so that the system is suitable for various types of signal engineering installation supporting equipment of railways in China.
