Method for real-time on-line monitoring of in-place state of switch machine

Abstract

The invention discloses a method for real-time on-line monitoring of the in-place state of a switch machine. The method comprises the following steps of enabling a video camera, an image processing plate and network transmitting equipment to be mounted at the position of a gap of the switch machine; calibrating the mounted video camera; after each movement of the switch machine, performing algorithm processing on acquired gap images of the switch machine by an image collection plate card; combining with calibration value of the video camera, calculating the actual position after each movement of the switch machine, and transferring the actual positions to an operation terminal by the network transmission equipment; and then monitoring whether the switch machine is normally in place, and judging whether a warning signal is sent or not. According to the method for real-time on-line monitoring of the in-place state of the switch machine based on mode recognition disclosed by the invention, the working condition of the switch machine can be stably and reliably monitored in real time, and the operation safety of railways is improved.

Description

technical field [0001] The invention belongs to the technical field of visual information analysis and pattern recognition, and in particular relates to a method for real-time online monitoring of the position status of a switch machine. Background technique [0002] A turnout is a connection device that realizes the intersection of two tracks, and it is a control device that a train must pass through when it transfers from one track to another. The switch machine is the driving device for switch conversion, and is the core part of the switch. Before the train passes the turnout, the point machine will drive the turnout to change its position according to the driving route. Therefore, the running quality of the switch machine directly affects the running efficiency of the train, and even leads to major accidents in severe cases. [0003] At present, the measurement of the in-place status of the switch machine mainly depends on the maintenance personnel to measure on the eq...

Problems solved by technology

At present, some switch machine online monitoring devices have appeared on the market, but all of them have the following problems: the image of the switch machine is compressed into a digital image, which is transmitted to the control terminal in a centralized manner, and is processed by the monitoring terminal, resulting in loss of image quality and processing The speed is slow, the real-time performance is not strong, and it is difficult to meet the requirements of real-time online monitoring
