Thermal infrared imager and laser radar based thermal infrared bow net operation monitoring system

Abstract

The invention discloses a thermal infrared imager and laser radar based thermal infrared bow net operation monitoring system. The thermal infrared imager and laser radar based thermal infrared bow net operation monitoring system comprises a thermal infrared imager, a laser radar, a visible light vidicon, a vehicle-mounted server, a massive mobile hard disk, a GPRS vehicle-mounted transmission module and a data inquiry analysis system. The thermal infrared imager, the laser radar and the visible light vidicon are arranged on the top of a locomotive and are connected with the vehicle-mounted server in the locomotive; the GPRS vehicle-mounted transmission module and the data inquiry analysis system are also connected with the vehicle-mounted server; and the massive mobile hard disk is arranged on the vehicle-mounted server. As temperature distribution of a bow net is detected by adopting the thermal infrared imager, the height of a conductor and a stagger value are detected by adopting the laser radar, and the parameters are transmitted to a scheduling room in real time through the GPRS data transmission network, installation of a detection sensor on a head of a pantograph is unnecessary, the weight of the head of the pantograph is not added, and accurate and real-time theoretical basis is provided for maintenance and post-accident inquiry of a contact network.

Description

technical field [0001] The invention relates to the technical field of track electrification, in particular to a thermal infrared pantograph-catenary operation monitoring system based on an infrared thermal imager and a laser radar. Background technique [0002] In the electrified railway, the catenary is the main power supply equipment of the electrified railway, and the electric locomotive obtains electric energy through the catenary. Pantograph-catenary relationship plays an important role in the normal operation of the entire electrified railway operation system. Pantograph-catenary arcing and pull-out exceeding the limit are the key factors that directly restrict the speed increase of electrified railways. With the increasing railway transportation volume and the continuous improvement of train running speed, it is imminent to develop an online monitoring system for pantograph-catenary operating status. [0003] At present, the means of online monitoring of pantograph-...

Problems solved by technology

[0003] At present, the means of online monitoring of pantograph-catenary operation status of electric locomotives are mainly to install proximity sensors and photoelectric sensors on the pantograph head to measure the pantograph-catenary, but this method increases the weight of the pantograph head of the locomotive. Destroy the dynamic characteristics of the pantograph head
