Abstract

The invention discloses a high speed rail braking method and a high speed rail braking system based on multiple intelligent bodies. The high speed rail braking method based on the multiple intelligent bodies includes the following step: step S110, using a braking device to receive external angle acceleration magnitude, and obtaining initial control parameter value according to a preset function relationship between the external angle acceleration magnitude and a control parameter value, and further includes the following steps: step S120, obtaining current angle acceleration magnitude of a plurality of wheel sets through detection; step S130, obtaining an actual control parameter value of each current wheel set according to a function relationship among the current angle acceleration magnitude, the current angle acceleration magnitude of two adjacent wheel sets, the external angle acceleration magnitude and the initial control parameter value of each current wheel set, which are preset; step S140, using the breaking device to brake the corresponding wheel sets according to the actual control parameter values, and returning to the step S110. The high speed rail braking method based on the multiple intelligent bodies can simultaneously consider influence factors between time delay constraint and each wheel set, and difference between braking effects of the high speed rail braking method based on the multiple intelligent bodies and expected braking effects is small, and furthermore braking accuracy is high.

Description

technical field [0001] The invention relates to the technical field of braking, in particular to a multi-agent-based high-speed rail braking method and system. Background technique [0002] In the high-speed train industry, especially in high-speed trains with higher speed levels, one of the most difficult core technologies is the development of the braking system, that is to say, the bottleneck of the braking technology is the restriction of the further increase of the speed of the high-speed train factor. [0003] At present, the braking system of high-speed rail usually adopts compound braking strategies, such as regenerative braking, resistance braking, air braking, etc. But no matter what form of braking control system is adopted, friction braking is still regarded as the main braking method of high-speed trains. According to the regulations of the European Union of Railways (UIC), when a high-speed train is running, it should be able to stop within a specified brakin...
