Embodiment Construction

[0067] like figure 1 As shown, this railway switch machine represents a rod gap video monitoring system, including:

[0068] The infrared camera 6 that is arranged on the switch machine site to be used to collect the image of the bar gap; the infrared camera adopts the infrared camera of OV96501.3 million pixels;

[0069] An image acquisition processor 5 is arranged on the site of the switch machine for image processing the collected notch image of the display rod to obtain the data of the notch of the display rod and the position information of the reverse position;

[0070] The starting current sensor 9 used to collect the starting current signal of the switch machine to control the infrared camera 6 to record the video of pulling the switch;

[0071] The vibration sensor 8 for collecting the vibration signal of the switch machine to control the infrared camera 6 to record the vibration video of passing the vehicle;

[0072] A temperature and humidity sensor 7 for collecti...

Abstract

The invention provides a video monitoring method and a video monitoring system of indication rod gaps of a railway point switch. An infrared camera is adopted by the system to collect an indication rod gap image; an original pixel image is processed and a characteristic parameter is extracted by an image acquisition processor at the filed of a point switch, so that precise calculation of the indication rod gap data is realized; and meanwhile, data of turnout wrenching process videos, cross-train vibration videos, live broadcast videos, current gap position images, gap position information, temperatures and humidity and the like are communicated and transmitted to an industrial personal computer of a monitoring station through a communication network. The system is rapid in transmission speed and process speed, strong in real time, high in image resolution and convenient in observation; in addition marks need not to be set, and transformation to the point switch is unnecessary, and no new cables need to be paved, so that the network can be constructed according to on-site situations flexibly; and the setup is more convenient.

Description

technical field [0001] The invention relates to the technical field of gap monitoring of a railway switch machine indication rod, in particular to a video monitoring method and system for a gap of a railway switch machine indication rod. Background technique [0002] With the rapid development of my country's railway modernization, the speed and density of trains have also been greatly increased. In order to keep the railway signal equipment in good quality, higher requirements are put forward for the efficient and scientific maintenance work. [0003] The switch machine is the main signal equipment of the railway turnout control system. In addition to being used for the switching and locking of the turnout, the switch machine indicates that the offset of the rod notch reflects the position and state of the switch point rail (and core rail) . [0004] There is an L-shaped notch indicator (mainly the vertical part of the indicator, and the horizontal part is only used for fi...
