Elevator Car Assignment via Zoning and Traffic Judgment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator systems face increased processing load during peak hours due to the need for zoning and floor assignment in multi-elevator buildings, which affects operation efficiency.
Innovation Solution
An elevator system with a car call registration device, building specification data storage, specially-assigned floor judgment, traffic condition judgment, and assignment control sections that manage car assignments based on traffic conditions and building specifications to optimize car allocation without increasing processing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If car call registration is performed in multiple halls with zoning and floor assignment for each car, then operation efficiency during peak hours is improved, but processing load increases remarkably
Solution Approach 1:
The patent segments the building into multiple zones with predetermined floor assignments for each zone. During peak hours, car calls are processed by assigning cars to zones rather than individually assigning floors to each car across the entire building. This segmentation reduces the computational complexity of car call processing while maintaining efficient elevator utilization during high-traffic periods.
2Loss of time
If zoning and floor assignment is performed for each car, then user waiting time is reduced, but memory requirements and processing complexity increase
Solution Approach 1:
The patent performs preliminary actions by pre-defining zones and their associated floor assignments before peak traffic periods begin. The zone configurations and floor assignments are established in advance and stored in the system memory. During peak hours, the system simply matches car calls to pre-defined zones rather than performing complex real-time floor-by-floor assignments, thereby reducing user waiting time without proportionally increasing processing complexity.

AI summary
An elevator system including a car call registration device by which an elevator user registers a car call before riding on a car and a group supervisory controller with a building specification data storage section in which building specification data including specially-assigned floors is stored. Further, a specially-assigned floor judgment section judges whether a departure floor is a specially-assigned floor when a car call is registered, and a traffic condition judgment section judges the traffic condition of elevators within a building. A car assignment is performed based on the traffic condition judgment section judging by the specially-assigned floor judgment section that the departure floor is a specially-assigned floor, and a car assignment is performed based on a building specification stored in the building specification data storage section when the specially-assigned floor judgment section judges the departure floor is not a specially-assigned floor.
