The invention provides a vehicle-mounted gateway power supply management system and a 25t axle load aluminum alloy coal hopper car. The vehicle-mounted gateway power supply management system comprises a plurality of battery assemblies, a plurality of first switches and a control device. The multiple battery assemblies and the multiple first switches are all arranged on the 25t axle load aluminum alloy coal hopper car. Each first switch is electrically connected with one battery assembly. And the control device is arranged on the 25t axle load aluminum alloy coal hopper car. The control device is electrically connected with the plurality of first switches and the plurality of battery assemblies. The control device is used for controlling the first switch to be switched on and off. And when the control device controls any one of the plurality of first switches to be switched on, the control device is also used for detecting the residual electric quantity of the battery assembly corresponding to the switched-on first switch and determining whether to control the switched-on first switch to be switched off or not according to the residual electric quantity. And when the first switch for controlling the conduction is switched off, the control device synchronously switches the conduction of the next first switch according to a set priority sequence.
Description
technical field [0001] This application relates to the technical field of railway wagons, in particular to a vehicle-mounted gateway power management system and a 25t axle load aluminum alloy coal hopper car. Background technique [0002] Railway transportation is characterized by high efficiency and environmental protection. With the development of the world economy, railway transportation can more and more reflect its advantages. With the rapid development of the world economy, the abundant transportation of bulk goods such as minerals, grains, and chemical raw materials has created a solid and stable material foundation for the long-term and efficient operation of world rail freight. During the operation of railway freight vehicles, multiple sensors are used to check the bottom door, top cover, train pipe pressure, brake cylinder stroke, pressure, operating vibration and other related parameters of railway freight vehicles, and send the inspection data to Vehicle Gateway...
