Background

With the development of economic technology, high-rise buildings are more and more. Often a large number of people exist in a high-rise building, and rapid trans-floor transportation of people is mainly performed by an elevator.

The conventional situation of the current elevator is that only one car moves up and down in one elevator shaft, which results in limited transportation capacity of the elevator, and often difficulty in meeting the requirement of people in high-rise buildings on the operation capacity of the elevator. If the elevator needs to stop once at each floor, more time is spent on going up and down the elevator, which can lead to overlong waiting time of the elevator and sometimes seriously affect the work or life of people. This situation is particularly pronounced during rush hour hours, and often results in elevator congestion, excessive waiting times, etc. Therefore, an increase in the operation amount of the elevator is demanded. This need is particularly pronounced in many places of the population, such as hospitals, malls, office buildings. In order to solve the demand of high-rise buildings for the operation amount of elevators, the current conventional approach is to increase the number of elevators. The requirement can be met by arranging at least 4 elevators and even more than 10 elevators in a high-rise building. Although this method can increase the operation amount of the elevator, it takes a lot of space to install the elevator shaft for elevator installation.

In order to increase the operation efficiency of the elevator and save the installation space, the existing mode is to design an annular rail elevator, a plurality of cabs are installed on the annular rail to circularly operate by arranging the annular rail between two elevator shafts, the existing annular rail elevator can be divided into the same operation mode and the independent operation mode, the same operation mode is that the elevator cabs are uniformly distributed on the annular rail, the same start and stop mode, that is, one of the cabs stops operating, the other cabs stop operating, the same operation mode can effectively ensure the operation safety of the elevator, no phenomenon of collision of cabs occurs, but the operation efficiency of the same operation mode is lower, the cabs are easy to idle, delay waiting time and can not ensure the operation amount of the elevator, the independent operation mode is that the cabs arranged on the annular rail operate independently, one of the cabs stops operating, the other cabs can not be influenced by the cabs, the operation efficiency of the cabs can continue operating, the operation of the cabs is improved, but the operation of the cabs is stopped independently operated, after the one of the cabs stops operating, the operation mode can effectively ensure the operation safety of the cabs, the collision of the cabs is easy to prevent the cabs from happening, the collision accident can not happen, the elevator is designed in detail, and the safety accident can not happen, and the elevator is not designed, and the safety accident can not happen, and the safety is considered.
