Railway Thermal Imaging Monitoring System

Yoseen infrared is a company focusing on the R & D, production and sales of temperature - measuring infrared thermal camera. Our thermal cameras are widely used in human body temperature measurement, metallurgy, power system, security and other fields.

System introduction System features User benefits: The system uses thermal camera to monitor the temp of pantograph and traction substation in the railway system online, so as to quickly and visually find the fault points and hidden dangers. The high-speed thermal camera can accurately detect the temp of the vehicle axle, so as to avoid the hot axle accidents.The system uses thermal camera to monitor the temp of pantograph and traction substation in the railway system online, so as to quickly and visually find the fault points and hidden dangers.

■ The thermal camera does not interfere with the normal operation of the equipment when monitoring, and the hidden trouble detection does not affect the normal operation of the train.

■ Non-contact thermal imaging detection greatly improves operation and maintenance efficiency and reduces personnel work intensity.

■ Thermal camera is widely used in railway system, mainly as follows:

● Internal combustion electric locomotive

● Electric locomotive parts

● Power supply system and components

● Locomotive and vehicle braking system

● Insulated car, reefer container

● Refrigeration equipment of air conditioning unit

● Railway communication signal equipment

● Locomotive pantograph

technical parameter

Electrified railway arch network transmits electric energy for electric locomotives, its quality and working condition directly affect the railway transport capacity and safety. As an overhead contact network set up in the open air, it is exposed to the outside all year long and is vulnerable to pollution, corrosion, friction, etc., resulting in lower quality, which further affects the locomotive power transmission and causes related safety problems. By infrared thermal imaging temperature measurement technology in the process of vehicle running, the observation of pantograph surface thermal state distribution, localization and diagnosis of bow net exceptions, has not suspended, do not contact, fast and intuitive features, through to the electrical equipment on the surface of the thermal analysis, judgment and diagnosis of equipment state and its hidden danger and defects, for the timely detection and treatment, prevent the happening of the accident have the effect of the key and effective.

Power equipment in the electric locomotive running produces heat in the process, some potential problems in the process of development will be embodied in the characteristics of the equipment and the fitting surface temperature changes, through the infrared thermal imager can be rapid and accurate for the scene temperature distribution within the equipment, match with the Yoseen Infrared Analysis Software for data processing algorithm and scene, locomotive internal devices found the problems in time, complete the diagnosis positioning, risk assessment, reduce the risk of accidents.
