Elevator dynamic monitoring and early warning system based on machine learning algorithm

open access: yesIET Networks, EarlyView., 2022
In order to monitor and warn the elevator dynamics, in this work, the machine learning algorithm is introduced, and the particle swarm algorithm is used to perfect the model. The model is optimised, and the experimental comparison shows that the optimisation of the model parameters can further improve the accuracy of the elevator load prediction. Then,

The unpaired operation of urban rail transit

open access: yesJournal of Shenzhen University Science and Engineering, 2023
In order to solve the problem of waste of transport resources on tidal lines of urban rail transit due to uneven passenger flow, during the transition from morning peak to afternoon peak and from afternoon peak to evening peak, the unpaired operation method using the existing parking lines to store cars is proposed. Taking into account the interests of
