Embodiment Construction

[0057] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention. It should be noted that, as long as there is no conflict, each embodiment and each feature in each embodiment of the present invention can be combined with each other, and the formed technical solutions are all within the protection scope of the present invention.

[0058] Aiming at the requirement of safe parking of maglev traffic in emergency situations, the present invention proposes a hierarchical braking control device and method, which can monitor the effect of braking control during control, so as to realize that the train can still be controlled when one type of braking fails. Stop safely where permitted. The hierarchical braking control device and method of the...

Abstract

The invention provides a graded braking method for a maglev train including an electric brake system, a mechanical brake system and an alighting brake system. The graded braking method for the maglevtrain comprises the steps of calculating a corresponding electric brake curve, a corresponding mechanical brake curve and a corresponding alighting brake curve for each brake mode of the maglev trainin real time according to obtained current line data, vehicle condition data and passenger comfort restriction condition, wherein each brake curve represents that the train triggers speed triggering thresholds of corresponding braking in different positions from a target speed reduction point under a situation of the current line data and the vehicle condition data in order to satisfy a target speed reduction requirement and satisfy a passenger comfort restriction condition before reaching the target speed reduction point.

Description

technical field [0001] The invention relates to the field of maglev trains, in particular to a control method for hierarchical braking of maglev trains. Background technique [0002] With the continuous and rapid development of my country's economy and the rapid progress of society, rail transit technologies such as high-speed rail, intercity, subway, and maglev have brought great convenience to people's daily travel. In particular, the low / medium / high-speed maglev trains that have emerged in recent years have been highly recognized by people for their advantages of speed, low consumption, environmental protection, and safety, and have a bright future. On May 6, 2016, my country's first medium and low-speed maglev commercial operation demonstration line with completely independent intellectual property rights - Changsha Maglev Express opened for trial operation. This line is the longest medium-low speed maglev operation line in the world. The maglev train on this line adop...
