Problems solved by technology

[0015] Again, the transmission line can be switched when the power of the single elevator control device 3 drops, and the elevator door information of the elevator door control device 6 is directly transmitted to the structure of the group management control device 10. Therefore, when the power of the group management control device 10 drops, The elevator entrance information of the elevator entrance call button 9 can only use a single elevator control device 3 for elevator service, so there is a problem of low elevator operation efficiency

Embodiment Construction

[0038] Various embodiments of the present invention will be described below with reference to the accompanying drawings.

[0039] Embodiment 1

[0040] figure 1 An example of the structure of the elevator group management control system of this invention is shown. exist figure 1 51 to 53 are single elevator control devices (represented as "CC"). 61 to 63 are communication control devices (indicated as "CL" in the figure) connected to the individual elevator control devices 51 to 53 . 4, 6, 8, 9, 10, 41-44 are the same as before.

[0041] 31 is a group management transmission path that connects the group management control device 10 and the communication control devices 61 to 63 with a bus. Reference numerals 54 to 56 denote respective transmission paths connecting the communication control devices 61 to 63 and the individual elevator control devices 51 to 53 . 11 is the elevator door transmission path connecting the elevator door control device 4 and the communication...

Abstract

A system comprises a plurality of individual-control devices for individually controlling elevators, a plurality of landing control devices buttons, a group-control device for carrying out assignment of the elevators based on landing information transmitted from the landing control devices, communication control devices having independent power sources connected to the individual-control devices, the landing control devices and the group-control device provided for the respective individual-control devices to perform data communication. Thus, a group-control system for elevators in which communication paths of the communication control device and the group-control device are connected by bus is constituted. Even if an individual-control device breaks down, communication between the landing control device and the group-control device is effective, and therefore the landing call buttons are not required to be connected to the landing control devices for backup, thereby simplifying the connection constitution.

Description

field of invention [0001] The invention relates to an elevator group management and control system that responds to call button information at an elevator entrance and performs allocation processing of multiple elevators. Background technique [0002] Figure 10 It is a configuration diagram showing a conventional elevator group management control system described in Japanese Patent Application Laid-Open No. 4-55272. [0003] exist Figure 10 Among them, 1 to 3 are elevator control devices for respectively controlling three separate elevators #1 to #3 (not shown), and 4 to 6 are elevator entrance devices 8 and 9, which are installed on each floor and also The elevator door control device (marked as "HS" in the figure) that is arranged on each elevator, 8 and 9 are the elevator door equipments that are connected to the elevator door call buttons and indicator lights of the elevator door control devices 4-6. [0004] exist Figure 10 In the case of the system shown, the eleva...
