Power management method and system for hydraulic brake system of magnetic levitation train, and rail vehicle

Abstract

The invention discloses a power management method and system for a hydraulic brake system of a magnetic levitation train and further discloses a rail vehicle comprising the power management system forthe hydraulic brake system of the magnetic levitation train. The power management method comprises the steps that a master-control electronic brake control unit (EBCU) is controlled to obtain the braking capacity values of carriages through a MVB network, and the total braking target value is obtained according to the braking capacity values of the carriages and carrying information of the wholetrain; according to the total braking target value, whether electric braking of the whole train is insufficient or not is judged; if yes, electric braking force is all distributed to the carriages, and hydraulic force is averagely distributed to the carriages, and the target values of the braking force needing to be applied of the carriages are obtained; and if not, pure electric braking force isdistributed to the carriages. A slave-control EBCU is controlled to receive the corresponding target values of the braking force needing to be applied, and the braking force is applied according to the target values of the braking force needing to be applied. The purpose that energy is fed back to a power grid to the maximum extent through the vehicle MVB network is achieved, energy sources are saved, abrasion of a braking pad is reduced, and the maintenance cost of the train is saved.

Description

technical field [0001] The invention relates to the technical field of rail vehicle control, and more specifically, to a power management method and system for a hydraulic braking system of a maglev train. In addition, the present invention also relates to a rail vehicle comprising the power management system of the hydraulic braking system of the maglev train. Background technique [0002] At present, most of the braking systems of medium and low-speed maglev trains adopt an independent control management strategy. The Electronic Brake Control Unit (EBCU, Electronic Brake Control Unit) of each car is completely independent and does not communicate with each other. The EBCU of each car is only responsible for applying the braking force of a single car. When the electric braking force of one car is insufficient, it can only be supplemented by the hydraulic braking force of this car, and cannot make full use of the remaining electric braking force of the other two cars. At th...
