Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the following examples are based on the premise of this technical solution, and provide detailed implementation and specific operation process, but the protection scope of the present invention is not limited to the present invention. Example.

[0044] A device suitable for detecting the safety state of the catenary operating environment in this embodiment adopts a laser radar matrix design, and the laser radar matrix emits pulsed lasers, which can cover the entire range of the catenary, and can accurately measure and calculate the catenary scan through the echo signal. The distance of the section from the lidar matrix. Then a large amount of ranging data is generated into a 3D point cloud, and the three-dimensional information of the catenary is reproduced in the computer, and then the information is compared according to the structural character...

Abstract

The invention discloses a device and a method suitable for detecting the operating environment safe state of a contact network. A laser radar matrix design is adopted, a laser radar matrix emits pulselaser to fully cover the range of the contact network, and the distance from a scanning cross section of the contact network to the laser radar matrix can be precisely calculated through an echo signal. Then 3D point cloud is generated by mass ranging data, and three-dimensional information of the contact network is reproduced in a computer; and thereafter, information is compared according to structural characteristics of the contact network, so that beyond limit object, such as dangerous trees and bird nests, in an operating environment of the contact network are discovered in time. The device can be permanently fixed to a train without temporarily mounting and detaching; and visual acquisition equipment is prevented from being used, so that the influence caused by weather change is excluded.

Description

technical field [0001] The invention relates to the technical field of catenary, in particular to a device and method suitable for detecting the safety state of the operating environment of the catenary. Background technique [0002] At present, the operation of electrified railway trains still uses pantographs to obtain continuous electric energy from the catenary in the form of sliding friction. The safety status of catenary operation environment directly affects the safety of train operation. [0003] The existing catenary operating environment detection is mainly based on image vision technology, such as the "Overall Technical Specifications for High-speed Railway Power Supply Safety Inspection and Monitoring System (6C System)" promulgated by the Railway Corporation. Among them, the 2C part uses vision technology to complete the catenary detection. The 2C system mainly installs the visual acquisition equipment in the train cab, and the sensor receives the external imag...
