Description

Point switch fault early warning system

Technical Field

The utility model belongs to the field of fault detection, and particularly relates to a point switch fault early warning system.

Background

The switch machine is an important basic device in the railway station interlocking system and is also an important device in the turnout switching system. Along with the rapid development of urban rail transit, the running speed of a train is continuously improved, the load is increased, the density is increased, and the bearing pressure requirement of turnouts is also continuously improved. These changes have also led to the development of switch switching system technology. But the close inspection of the turnout still adopts the old method of manually and periodically inspecting, judging and adjusting the gap between the detection surface of the inspection column and the gap of the indication rod by visual inspection. How to automatically dynamically monitor the sealing strength of the turnout and timely master the gap change information of the gap is an important subject for ensuring the railway transportation safety. The change of gap size of the gap is shown by the switch machine, the change of the joint intensity of the turnout is reflected, the gap state of the gap shown by two sides of the switch machine inspection column is monitored in real time, the joint intensity of the turnout can be mastered, the rail transit operation efficiency can be improved by early warning in time, and the switch machine plays an important role in the safe operation of the turnout and the conversion equipment.

At present, although various intelligent detection methods for indicating gaps exist in the market, the defects that a detection sensing head is easy to wear and is not visual generally exist. In addition, for electro-hydraulic switch equipment, several important inherent characteristics are important for daily maintenance, for example, the hydraulic system of the electro-hydraulic switch machine cannot work normally due to oil shortage of an oil tank, the pressure of an oil cylinder can represent the change of turnout resistance, the maintenance period of the electro-hydraulic switch machine can be determined according to the conversion frequency, and the conversion time can reflect the efficiency of the switch machine conversion system. At present, signal maintainers can only go to manual testing on site, which is troublesome, time-consuming and labor-consuming, and increases the personal casualty risk on the signal maintainers. The railway turnout conversion equipment is used as important railway signal equipment in train operation, becomes one of main focuses of railway operation safety, and is an indispensable component for ensuring the safe operation of trains. However, the health decline of the railway switch conversion equipment often becomes a safety hazard causing accidents, and more planned and targeted maintenance and repair work needs to be carried out. At present, the monitoring means of the turnout switching equipment mainly depends on the operation power and current data curves of the turnout switch in a signal centralized monitoring system and the state parameters of a gap value, a gap image, oil pressure, oil level, temperature and humidity and the like in gap monitoring. The mode depends on manual experience, and is difficult to meet the complex working environment requirement of turnout switching equipment and the railway operation maintenance requirement of quickly positioning and repairing the fault. Therefore, a point switch fault early warning system is needed to collect various data for analysis and achieve fault diagnosis and early warning in advance.
