Heat dissipation abnormity early warning system for urban rail braking energy feedback device

The invention provides an urban rail braking energy feedback device heat dissipation abnormity early warning system, and relates to the technical field of braking energy feedback device heat dissipation abnormity early warning. Data of the temperature of an air inlet where the braking energy feedback device is located, the air speed of the air inlet, the current in a fan circuit, the rotating speed of blades on a fan, the temperature of a heat dissipation substrate of the braking energy feedback device, the temperature of an air outlet and the air speed of the air outlet are monitored and collected in real time. Omnibearing monitoring and analysis are carried out from the angles of the air inlet, the air duct, the fan, the heat dissipation substrate and the air outlet, collected data are transmitted to the early warning display platform, the early warning display platform is used for analyzing the abnormal heat dissipation condition of the urban rail braking energy feedback device, early warning display is ca
