Embodiment 1

[0049] In Embodiment 1, the online monitoring system 4 is connected between the RBC ISDN server 22 and the first impedance converter 23 through a three-way connector 41 . Specifically, the three-way coupler 41 is connected to the network cable 24 , and the online monitoring system 4 is connected to the three-way coupler 41 . The network cable 24 is used to connect the RBC ISDN server 22 and the first impedance converter 23, thus making the RBC I FIX The data of the interface is sent all the way to the first impedance converter 23 (referred to as the original I FIX interface line), all the way to the online monitoring system 4 (called monitoring line).

[0050] The online monitoring system 4 may include: a high-resistance isolation box 42 , a collection box 43 , a monitoring device 44 , and a monitoring system server 45 .

[0051] Wherein, the high-resistance isolation box 42 is connected to the three-way connector 41 and is used to isolate the online monitoring system 4 and ...

Embodiment 2

[0079]In the second embodiment, the online monitoring system 5 is connected between the first impedance converter 23 and the GSM-R network 3 through a three-way connector 51 . Specifically, the three-way coupler 51 is connected to the coaxial cable 25 , and the online monitoring system 5 is connected to the three-way coupler 51 . The coaxial cable 25 is used to connect the first impedance converter 23 and the GSM-R network 3, thus making the I of the RBC FIX The data of interface, after the first impedance converter 23, is sent to GSM-R network 3 (being called former I) all the way. FIX interface line), all the way to the online monitoring system 5 (called monitoring line).

[0080] The online monitoring system 5 may include: a second impedance transformer 52 , an acquisition box 53 , a monitoring device 54 , and a monitoring system server 55 .

[0081] Wherein, the second impedance converter 52 is connected to the three-way connector 51 to prevent line mismatch.

Abstract

The invention discloses an online monitoring system of a China train control system (CTCS)-3 grade train control system. The radio block center integrated services digital network (RBC ISDN) server of the ground subsystem of the CTCS-3 grade train control system is connected with a first impedance transformer by a network table through an I<FIX> interface; the first impedance transformer is connected to a global system for mobile communications-railway (GSM-R) network through a coaxial cable; and the monitoring system is connected between the ground subsystem and the GSM-R network through a three-way coupler to acquire the data in the I<FIX> interface of the RBS of the ground subsystem in real time to obtain monitored data, and analyzes, records and stores the acquired monitored data. When the embodiment of the invention is used, the wireless communication data and operation conditions between the RBC and the automatic train protection (ATP) are monitored in real time and displayed synchronously. Meanwhile, the invention also provides the data resolution, query, analysis and export functions of all radio communication layers.

Description

technical field [0001] The invention relates to the technical field of train control, in particular to an online monitoring system of a CTCS-3 train control system. Background technique [0002] With the rapid development of my country's high-speed railway construction, more and more lines adopt CTCS-3 train control system. CTCS-3 train control system includes on-board subsystem and ground subsystem. The ground subsystem is composed of several devices, and the radio block center (RBC: Radio Block Center) is its core device. [0003] RBC is a computer control system based on the principle of signal failure safety. It provides information for trains entering its jurisdiction based on track occupancy information, line data, temporary speed limit information, and route status information given by the interlocking system. Driving permit, the driving permit is then transmitted to the train overspeed protection (ATP: Automatic Train Protection) equipment on the vehicle through th...
