The invention belongs to the technical field of rail transit vehicle braking, and discloses a magnetic track braking system and a magnetic track braking control method. The magnetic track braking system comprises a power supply, a control device and an electromagnet assembly. The electromagnet assembly comprises an iron core part, a pole shoe part below the iron core part and a coil group consisting of a plurality of groups of coils; the coils in the coil group are arranged in the length direction or the width direction of a rail, and adjacent coils are insulated and isolated; and the coils in the coil group are divided into a plurality of independent groups, and the control device independently controls the independent groups of coils and gradually increases or decreases the number of excitation coils, so that the magnetic force of the electromagnet assembly is gradually controlled. The electromagnet assembly of the magnetic track braking system is provided with a plurality of sets of electromagnetic coils which are independently controlled, and the magnetic gradient change of the electromagnet assembly is controlled by controlling the number of magnet exciting coils. When a local coil breaks down, other independent groups can still work normally, so that the whole magnetic track braking system is degraded for use.
本发明属于轨道交通车辆制动技术领域,包括一种磁轨制动系统,还包括一种磁轨制动控制方法。其中磁轨制动系统包括电源、控制装置以及电磁铁组件。电磁铁组件包括铁芯部、铁芯部下方的极靴部以及由多组线圈组成的线圈组;线圈组中的各线圈沿着铁轨的长度方向或宽度方向排列,且相邻的线圈之间绝缘隔离;线圈组中的线圈分成若干独立组,且控制装置对各独立组线圈独立控制,并逐渐增加或减少励磁线圈的数量,从而逐步控制电磁铁组件的磁力。该磁轨制动系统的电磁铁组件设置有多组电磁线圈,各组线圈独立控制,并通过控制励磁线圈的数量来控制电磁铁组件的磁力梯度变化。当局部线圈故障时,其他独立组依然可以正常工作,使整个磁轨制动系统降级使用。
