Intelligent comprehensive monitoring system of railway switch and method

Abstract

The invention relates to an intelligent comprehensive monitoring system of a railway switch and a method; the system comprises a pressure measuring device, a liquid level measuring device, a gap monitoring device and a current transformer; the pressure measuring device is used for measuring the change data of the pressure of a hydraulic loop of the railway switch during the conversion process of the railway switch; the liquid level measuring device is used for measuring the change data of the liquid level of an oil cylinder of the railway switch when the conversion process of the railway switch is over and the work is stopped; the gap monitoring device is used for acquiring a gap deviation value after the conversion process of the railway switch is over and the work is stopped; the current transformer is arranged on a power cord of the railway switch, and is used for sending a starting signal or a sensing stopping signal to the pressure measuring device, the liquid level measuring device and the gap monitoring device; and according to the intelligent comprehensive monitoring system of the railway switch and the method, the changes of pressure and the liquid level of the oil cylinder when the railway switch acts can be monitored in real time and a measuring mode can be changed, so that an indication lever does not need to be changed when a target is installed, the data transmission pressure is reduced, and communication construction is prevented.

Description

technical field [0001] The invention relates to an intelligent comprehensive monitoring system and method for a railway switch machine. Background technique [0002] The electro-hydraulic switch machine in the railway switch machine is a device powered by high-pressure hydraulic oil to switch the switch. Its main working parameters include: hydraulic circuit pressure, oil cylinder liquid level, indicating rod gap offset value, etc. The existing railway switch machine lacks a comprehensive monitoring device, and only has a single gap deviation monitoring device. For the above parameters, the main methods and existing problems of current measurement are as follows: [0003] 1. Hydraulic circuit pressure [0004] At present, the working pressure of the hydraulic circuit of the railway point machine can only measure the average pressure through an external pressure gauge when the line is idle. However, there is no mature method for the real-time pressure change in the real wor...

Problems solved by technology

[0012] 2) The optical system has weak anti-pollution ability

[0013] 3) There is no environmental detection device, and it cannot filter the external interference factors that affect the measurement accuracy, and the false alarm rate is high

[0014] 4) The construction is difficult

[0016] 6) Lack of notch offset direction indicator

For the above gap monitoring methods, due to the defects of the scheme, it is impossible to set the gap offset direction indicator device on the terminal, and the maintenance personnel have to manually adjust the gap adjustment, which is very inconvenient
