Problems solved by technology

[0010] However, in the technology described in Patent Document 1, only the number of waiting passengers at the landing is considered, and the status of the car with the door opened is not considered. When the waiting car with the door open is opened, as a result, the next waiting car with the door closed cannot be opened until the waiting car reaches the specified load or the specified time elapses

Embodiment 1

[0033] Elevator systems, as longitudinally moving units in buildings, transport numerous users smoothly and safely every day. Especially in large buildings, due to the large number of users, multiple elevators are installed, and the group management system manages these multiple elevators as a group for unified management.

[0034] One of the most important performance indicators of an elevator system is the conveying force (calculated from the number of people conveyed / the required time) for the number of people conveyed per specified time. How to improve it when the office building is crowded during working hours and lunch time? Countermeasures against conveying force are very important. The key to improving transportation capacity is to transport more people in a shorter period of time. As a solution to this, focus on the efficient use of elevator cars waiting at elevator landings on congested floors such as lobby floors.

[0035] Here, first, the control of the waiting el...

Embodiment 2

[0194] The elevator group management system of Embodiment 2 will be described. In addition, the description of the same parts as in the first embodiment will be omitted.

[0195] Figure 14 It shows the functional block diagram of the whole system mainly based on the door open standby control, and shows the figure 2 different implementations. exist Figure 14 in, with figure 2 The same parts are also given the same reference numerals, and their descriptions are omitted here.

[0196] exist Figure 14 in, with figure 2 The different parts are the internal processing of the real-time determination unit 141 implementing the door-open standby and the entering passenger number calculation unit 146 of the door-open standby car. Here, the calculation unit 146 for the number of passengers who can enter the waiting car with the door open is the same as figure 2 The processing is the same as that of the calculation unit 1411 for the number of passengers who can enter the wai...

Abstract

The purpose of the present invention is to ensure, at times of congestion when users are arriving successively at an elevator landing, that elevator cars standing by at the elevator landing on that floor are controlled effectively, thereby enabling the users to efficiently board the elevator cars without wasting time and improving the overall transport capacities of group-control elevators. To achieve the foregoing, this elevator group control system controls the operation of multiple elevator cars, wherein the system comprises: a means for detecting the number of users present at an elevatorlanding on a prescribed floor; a means for detecting the number of riders inside elevator cars that are stopped with open doors at this prescribed floor; a means for calculating, on the basis of suchnumber of users at the landing and such number of riders inside the cars, the number of elevator cars to be stopped with closed doors at the prescribed floor; and a means for opening the doors of anyelevator cars that are stopped with closed doors at this prescribed floor.

Description

technical field [0001] The invention relates to an elevator group management system for unified management of multiple elevators. Background technique [0002] An elevator system is a vertical transportation system in a building. In a particularly large building, the elevator system is composed of a system consisting of multiple elevators and elevator group management that collectively manages these elevators as a group. The purpose of this type of elevator system is to transport as many users as possible to their destination floors per specified time, which is especially important when there is congestion during work or lunch. [0003] For example, the technology described in Patent Document 1 describes a control example in which the number of waiting passengers on a specific floor is detected, and the car with the doors waiting for the largest number of passengers is selected as the next door-opening waiting car. [0004] In addition, in the technology described in Patent...
