To reduce the lateral movement time of elevator passengers in large-span high-rise buildings, a circulatory multipath elevator design scheme is proposed. To reduce the complexity of the circulatory multipath elevator control process due to the increase in the number of lift cars, a circulatory multipath elevator control system framework is established based on digital twin technology. To ensure the safe operation of the elevator, a lift car following model is established, and a circulatory multipath elevator collision avoidance strategy is designed. The lift car collision avoidance strategy can effectively reduce collision accidents in the process of multi lift car operation and ensure the safety of elevator passengers.
