Interconnected elevator system and operation control method thereof

Abstract

The invention discloses an interconnected elevator system. The interconnected elevator system comprises at least two elevators; every elevator comprises an elevator controller, wherein at least one group is automatically established according to the configuration information through the elevator controller; every elevator controller is used for sending the running state information and the calling information of the self-elevator-controller and receiving the related information which is sent from other elevator controllers arranged in the same group; the same calling allocation algorithm is applied to the elevator controllers which are arranged in the same group; a self-allocation-instruction is given according to the same allocation result obtained through calculation through every elevator controller for running. The invention also provides a running control method of the interconnected elevator system. According to the interconnected elevator system and the running control method thereof, the group with the group allocation function is formed without a group controller or a master control type interconnected system, the forming mode of the group is flexible and variable, the allocation result information does not need to be sent on a bus which is arranged in the group, and accordingly the system communication overhead is small and the group allocation of more elevators can be achieved under the same system resource condition.

Description

technical field [0001] The invention relates to an elevator system, and specifically belongs to an interconnected elevator system and an operation control method thereof. Background technique [0002] With the wide application of elevators, it is more and more common to use two or more elevators in buildings. In order to achieve energy saving and improve distribution efficiency, group control system elevators have emerged as the times require, such as invention patents CN200580051572.1 and The elevator system disclosed in CN01132157.1 can indeed effectively improve the distribution efficiency and reduce the overall energy consumption of the elevator group. However, this group control elevator system also has some disadvantages, for example, an additional group controller is required in the system, and the elevator cannot continue to distribute calls reasonably when the group controller fails. [0003] In view of this, there has been an elevator interconnection system that d...

Problems solved by technology

However, this group control elevator system also has some disadvantages, such as the need for an additional group controller in the system, and when the group controller fails, the elevator cannot continue to distribute calls reasonably

[0003] In view of this, there has been an elevator interconnection system that does not require a group controller, such as the elevator interconnection group control system disclosed in the invention patent applications with application numbers 201010196017.0 and 201010196026.X. Although it can basically solve the aforementioned problems, this This kind of elevator interconnected group control system adopts the master control method. The elevator control boards that make up the group control group are divided into group control master and group control slave. The role of the group control master is to generate dispatching signals and assign elevator cars to Passengers, each elevator control board in the whole system not only sends its own running status and received call information to the group control host, but also receives the distribution results transmitted by the group control host, so the amount of information transmission in the group control group is very large. Large, occupying most of the communication resources in the system

In addition, the interconnected group control system of this master control mode is less flexible, and only one group control group can be established.
