Abstract

The invention provides a detection method and device for a temperature rise fault of a train electric appliance cabinet and a terminal device, and the method comprises the steps of obtaining the thermal parameter variable values of at least one type of devices in the train electric appliance cabinet, and carrying out simulation parameterization of the thermal parameter variable values of the devices, and obtaining the simulation parameters; establishing a geometric simulation model of the train electric appliance cabinet and the at least one type of devices; according to the simulation parameters and the geometric simulation model, obtaining a train electric appliance cabinet multi-physics field coupling simulation model; extracting a temperature threshold value of the at least one type of devices of the train electric appliance cabinet multi-physics field coupling simulation model under different working conditions; obtaining the real-time temperature of the at least one type of devices through the thermal imaging principle, and when the real-time temperature is larger than the temperature threshold value of the corresponding device, carrying out fault alarming on the corresponding device. According to the invention, a complex monitoring module is not needed for circuit detection, and the overall temperature field of the train electric appliance cabinet is obtained by using the thermal imaging principle, so that the working state of the train electric appliance cabinet is more visually displayed, and the occurrence of judgment errors is further reduced.

Description

technical field [0001] The invention belongs to the technical field of electrical cabinet detection, and in particular relates to a detection method, device and terminal equipment for a temperature rise fault of a train electrical cabinet. Background technique [0002] The train electrical cabinet is not only the hub for the power distribution of the various components of the train, but also the control center to ensure the normal power distribution of each line in the power supply line. Therefore, the normal operation of the train electrical cabinet is the key to the normal operation of the train. [0003] There are many and complex circuits in the train electrical cabinet itself, and some circuit failures will inevitably occur, which will lead to fire accidents in the train electrical cabinet. Therefore, the safety inspection of the train electrical cabinet is the top priority for preventing train fire accidents. At present, the detection of the internal temperature rise o...
