Elevator Group Control Standby Positioning for Hall Call Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator group management control systems do not effectively determine and implement optimal standby actions for one-shaft multicar system elevators after service completion, leading to inefficiencies in responding to hall calls.
Innovation Solution
An elevator group management control device with a determination section to assess service completion and an instruction section that sets cars on standby using specific patterns, such as main floor, upper floor, or intermediate floor distribution, to optimize elevator positioning for quick response to hall calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple cars are arranged in a one-shaft multicar system, then the transportation volume of longitudinal traffic is increased, but the standby positioning efficiency after service completion deteriorates
Solution Approach 1:
The patent applies local quality by assigning different standby floor patterns to different cars based on their specific service completion status and building traffic characteristics. Each car is positioned at optimally different floors (e.g., one car at lower floors, another at upper floors) rather than all cars at the same floor, creating localized optimization that improves overall response efficiency while maintaining high transportation volume.
Solution Approach 2:
The patent implements dynamics by making the standby floor assignment flexible and adaptive rather than fixed. The control device dynamically determines standby floors based on real-time conditions including which service is completed, current traffic patterns, and building usage characteristics. This dynamic repositioning allows the system to maintain optimal efficiency as conditions change throughout the day.
2Speed
If distributed standby is implemented, then the response speed to hall calls is improved, but the complexity of standby pattern determination increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing multiple standardized standby floor patterns (first pattern with main floor and lower floor, second pattern with main floor and upper floor, third pattern with upper floors only). These patterns are predetermined based on common traffic scenarios, so when a service completes, the control device can quickly select from these pre-planned options rather than calculating optimal positions from scratch, reducing determination complexity while maintaining fast response speeds.
3Adaptability or versatility
If multiple standby patterns are used, then the adaptability to different traffic scenarios is improved, but the control system complexity increases
Solution Approach 1:
The patent applies parameter changes by varying the standby floor assignments across different patterns (changing which floors are selected as standby positions). The control device selects among three distinct parameter configurations: first pattern uses main floor plus lower floor, second pattern uses main floor plus upper floor, and third pattern uses only upper floors. This parameter variation allows adaptation to different traffic scenarios without requiring complex control logic, as each pattern represents a simple, pre-defined configuration.

AI summary
Provided is an elevator group management control device capable of appropriately setting standby actions to be carried out when services of one-shaft multicar system elevators have been completed. For this purpose, the elevator group management control device includes a determination section which, for a plurality of elevators including a one-shaft multicar system elevator in which a plurality of cars are arranged in a same shaft, determines whether services to elevator calls have been completed and an instruction section in which, in the case where services of a plurality of cars of a one-shaft multicar system elevator have been completed, as floors at which a plurality of cars in question are put on standby, any of patterns is set among a first pattern in which a main floor in the vicinity of a bottom floor and a floor lower than the main floor are set, a second pattern in which the main floor and an upper floor are set, and a third pattern in which upper floors are set, respectively.
