Embodiment 1

[0127] See figure 1 , figure 2 The present invention discloses a semi-automatically blocked railway rail breakage monitoring system. The monitoring system is provided with at least one monitoring section, and each monitoring section is provided with monitoring equipment.

[0128] Each set of monitoring equipment adopts a dual redundancy method, which is divided into main use and backup. If one set of equipment fails, the backup equipment will be automatically put into use, and an audible and visual alarm will be issued to indicate the failure of the field equipment.

[0129] The monitoring equipment includes a DC power supply, a monitoring host, an information acquisition module, and a GPRS data transmission module; the monitoring host is respectively connected to the DC power supply, an information acquisition module, and a GPRS data transmission module.

[0130] The information collection module includes several rail DC resistances, several rail short-circuit lines, circuit protec...

Embodiment 2

[0171] The broken track monitoring system is a system suitable for non-electrified semi-automatic block sections and can monitor the integrity of the track connection in the measured section in real time. It can actually detect and analyze abnormal data of track connection integrity, and issue an alarm in time.

[0172] Semi-automatically blocked section interval rail break monitoring requires the rail as a wire to ensure that each rail passes a certain current. When the rail breaks, the loop current is cut off and an alarm message is sent.

[0173] The section to be semi-automatically blocked is generally about 8Km, and a monitoring section is set up. A power transmission terminal is installed outside the insulated joint of the track circuit at a distance of 1200 meters to 1400 meters outside the incoming signal, and the incoming signal is in the adjacent station. A short-circuit line is installed near the outer side of the track circuit insulation joint at a distance of 1200 mete...

Abstract

The invention discloses a semi-automatic block railway steel rail breaking monitoring system and method. The monitoring system is provided with at least one monitoring section, and each monitoring section is provided with monitoring equipment. Each piece of monitoring equipment comprises a direct current power source, a monitoring host, an information acquisition module and a data transmission module, wherein the monitoring host is connected with the direct current power source, the information acquisition module and the data transmission module; and the information acquisition module comprises a plurality of steel rail direct current resistors, a plurality of steel rail short-circuit wires, a circuit protection voltage dependent resistor, a low-frequency choking coil and an adjusting current limit resistor. Each monitoring section is divided into a plurality of segments, and two steel rails comprise the first steel rail and the second steel rail. The segments of the first steel rail and the second steel rail are each provided with the corresponding steel rail direct current resistor, and each segment of the first steel rail is connected with the corresponding segment of the secondsteel rail through a short-circuit resistor. The semi-automatic block railway steel rail breaking monitoring system and method provided by the invention can be used for monitoring steel rail breakingand ensuring the safety of railway traffic.

Description

Technical field [0001] The invention belongs to the technical field of rail break monitoring, and relates to a rail break monitoring system, in particular to a rail break monitoring system for semi-automatically blocked railway rails; meanwhile, the invention also relates to a method for monitoring rail breakage of semi-automatically blocked railway rails. Background technique [0002] With the rapid development of my country's railway industry and the increase of train speed, higher requirements are put forward for the safety and efficiency of railway transportation. Therefore, it is an important issue to perform real-time rail break detection on rails on railway operating lines to ensure that the principle of "failure-safety" can be met when rail breakage occurs. For existing high-speed railways and normal-speed railways with automatic block sections, all railway signal equipment has been installed with track circuits, realizing rail break inspections. However, the semi-automa...
