A multi-intelligence federated reinforcement learning (FRL)-based vehicle-road cooperative control system and method at the complex intersection use a vehicle-road cooperative control framework based on the Road Side Unit (RSU) static processing module and the vehicle-based dynamic processing module. The historical road information is supplied by the proposed RSU module. The Federated Twin Delayed Deep Deterministic policy gradient (FTD3) algorithm is proposed to connect the federated learning (FL) module and the reinforcement learning (RL) module.

Secondly, FTD3 realizes the deep combination of FL and RL by aggregating target critic networks with smaller Q-values. Thirdly, RSU neural network participates in aggregation rather than training, and only shared global model parameters are used.

Abrégé
The present invention relates to the field of fluid machinery, and relates to a multi-stage pump for improving anti-blocking and anti-wear performances by utilizing internal circulation high-pressure water jet. Due to the fact that the situation that a multi-stage pump transports sand-containing water is relatively common, the problems such as abrasion, wear, and operation jamming of a key hydraulic component are always key problems restricting the high-speed development of the multi-stage pump. A drainage pipe is combined with a jet ring, and a pressure difference is used for leading out internal circulation high-pressure water to impact a gap part of an impeller outlet and a pump housing, such that solid particles are prevented from being deposited in a front pump cavity to cause wear or operation jamming, meanwhile, the secondary backflow is inhibited, and the hydraulic performance is improved. The invention is mainly used in industries, in which transport mediums contain solid particles, such as deep-sea mineral exploration, mine drainage and sand discharge, and sewage treatment.
