Problems solved by technology
The problem is that the temperature sensors installed at intervals cannot detect the whole catenary, and the detected temperature of the catenary is easily affected by the temperature sensor. Once the position of the temperature sensor shifts, aging and other problems, the detected temperature will be distorted, reaching less than expected effect
Can this system be used to monitor electrified railway catenary? Will it be affected by environmental factors such as clouds, fog, and rain? Will a high-speed electric locomotive affect the accuracy of the collected data? How can the collected data be processed to determine whether there is a defect in the catenary? These questions have not yet been studied, and naturally there are no answers.

The invention discloses infrared temperature monitoring method and system of an electrified railway contact network. The infrared temperature monitoring system comprises an infrared temperature monitoring device, a server and terminal display equipment, wherein a vehicle-mounted software centralized control system is arranged in a server and comprises an infrared thermal image data analyzing and processing module, a storage module, a display module and an image database management module; the system acquires a visible picture with contact network information and a thermal image graph with temperature data by using the infrared temperature monitoring device; after being analyzed and processed by various modules of the vehicle-mounted software centralized control system in the server, related data are stored and displayed through the terminal display equipment; and when the defectiveness is found, the system starts alarming. The invention has the advantages that the electrified railway contact network can be quickly detected by adopting the non-contact shooting of infrared and visible light images, which not only ensures normal running of an electric locomotive, but also can monitorthe contact network in real time and can find hidden troubles in time.
Description
technical field [0001] The invention relates to the field of electrified catenary monitoring, in particular to an infrared temperature monitoring system and method for electrified railway catenary. Background technique [0002] In order to meet the needs of economic development, electric locomotives have made electrified railways the development direction of railway systems in various countries due to their advantages such as fast speed and no pollution to the environment. Major problems such as power outages and railway system outages. In order to ensure smooth power supply lines and normal operation of electric locomotives, it is necessary to continuously detect the catenary that provides power for electric locomotives. [0003] There are various equipment and methods for catenary detection, such as: 1. Manual detection. Manual detection is the most basic method. The staff use infrared thermometers to regularly locate and detect the temperature of the catenary to detect ...
