[Abstract]:With the development of urbanization, elevators, as the only vertical transportation system in buildings, have been paid more and more attention. The performance and service quality of elevators are also being improved. The traditional single-car elevator in a single shaft can no longer meet the need of vertical traffic in modern high-rise buildings. A new type of "one well and more ladder" multi-car elevator system emerges as the times require. Increasing the number of elevator cars in an elevator shaft to improve the lift transportation efficiency is the current international solution to the transport efficiency of high-rise buildings and reduce the area occupied. The latest way to save energy and reduce construction costs. In this paper, the multi-objective optimization of the waiting time, riding time and energy consumption of multi-car elevator is made, and the optimization strategy of multi-car elevator system and the problem of safe collision avoidance of multi-car elevator system are discussed. A security verification method for optimal collision avoidance logic programming and an optimal scheduling algorithm based on particle swarm optimization and genetic hybrid algorithm are proposed. The research in this paper has good application prospects and practicability. The main work of this paper is as follows: (1) referring to a large number of domestic and foreign related materials, combined with the multi-car elevator system control technology development trends at home and abroad, In this paper, the optimal collision avoidance logic programming and Particle Swarm genetic Hybrid algorithm for multi-car elevator system are studied. (2) the system structure of multi-car elevator system is discussed. According to the different operation modes of the elevator car, the multi-car elevator system is divided into the double-deck car elevator system, the circulation multi-car elevator system and the single-shaft multi-car elevator system. (3) the multi-objective optimization mathematical model is established for the multi-car elevator system. Aiming at the three performance control objectives, the average waiting time, the average riding time and the running energy consumption of the multi-car elevator system, three performance control objectives are proposed. A multi-objective optimization model for the control system of the circulatory multi-car elevator is established. (4) aiming at the collision avoidance problem of the multi-car elevator system, according to the safe operation criteria of the control system of the multi-car elevator, In this paper, the collision avoidance control problem of cyclic multi-car elevator system is analyzed, and the logic programming method based on optimal collision avoidance is studied. In this paper, a new algorithm of safe obstacle avoidance for elevator car is proposed, and an optimized formula for avoiding collision is established. Thus avoiding the collision of the car selected in the ladder in the well. The simulation results show that the proposed method is feasible and effective, and can ensure the safe operation of the control system of the circulatory multi-car elevator. (5) for the waiting time and the ladder time of the multi-car elevator, This paper presents an optimal scheduling scheme for multi-compartment elevator system based on particle swarm optimization (PSO) and genetic hybrid algorithm (PGA), which is based on the multi-objective optimization formula established by three objectives of system energy consumption, such as waiting time, ladder time and system energy consumption. Compared with the traditional genetic algorithm, the experimental simulation is carried out, and the simulation diagram is analyzed. The results show that the PSO / GA method is effective. The realizability and superiority of multi-car and multi-objective optimization are discussed. (6) the contents of this paper are summarized and the future work is prospected.
