Description

Technical Field [0001] The present invention relates to a real-time monitoring system for a train operation control apparatus,

The present invention relates to a system for monitoring a plurality of rectifiers for a train operation control apparatus in real time, and more particularly, to a system for monitoring a plurality of rectifiers for a train operation control apparatus, To a plurality of rectifier real-time monitoring systems for a train operation control apparatus configured to display an operation state or a fault state of rectifiers in real time to easily monitor a state of a rectifier that supplies power to a train operation control facility .

Generally, various train operation control equipments, such as train automatic control unit (ATC), module power supply of train detection unit (TD), and line changeover unit, which have a direct relation with electric train operation, And is supplied with the power converted into DC power without being supplied.

Accordingly, in the control room for controlling the train operation, a power supply facility including a plurality of rectifiers for train operation control equipment is operated in order to convert AC power to DC power and supply the train operation control equipment. As a technology for a rectifier, there are technologies such as a high-frequency rectifier for a railway signal device in Korean Patent No. 10-0925543. In this case, since power supplies of different voltages such as 24V, 28V, and 48V are to be supplied according to the train operation control equipment supplied with power, the power supply equipment includes several to several tens of rectifiers for train operation control equipment having different output power values .

Since the rectifiers for the train operation control equipment have a direct relation with the essential train operation control facilities for normal train operation, if the function of the rectifier for the train operation control facility is abnormal, the electric train operation can not be normally performed However, large accidents can occur depending on the situation, and regular inspections are carried out to manage them.

However, such rectifiers generally correspond to equipments that can be used for several to several decades unless there is an abnormality such as a serious defect or failure of the equipment once it is installed, while a rectifier with a long production period has its own rectifier In order to manage such spherical rectifiers, there is no means for confirming the state of the rectifier. In order to manage such rectifiers, conventionally, a manager has used a voltage / current measuring device such as Korean Patent Laid-Open Nos. 10-1998-0049937 and 10-2000-0008050 The output power value of each of the rectifiers was checked while directly measuring.

However, in the above-described conventional rectifier checking method, it is difficult to check the state of the rectifiers in real time because the state of the rectifier can be confirmed only at the time of checking. In addition, when some rectifiers are abnormal, There is a problem that it is difficult for a few administrators to manage a large number of rectifiers having different characteristics such as the output power capacity because the output power value of the rectifiers must be checked while measuring them one by one.
