Elevator Group Control System with Destination Input and Head-Count Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elevator group control systems require users to manually confirm the number of people before inputting it, leading to inconvenience and low operation efficiency, especially when a large number of users need to be accommodated, resulting in prolonged waiting times.
Innovation Solution
An elevator group control system that includes a destination operating panel, a group boarding registering device, a user head-count storage section, and an assigned car determination section, allowing users to register group use with a simple button press, pre-storing expected user counts, and dynamically assigning cars based on available capacity and response evaluation values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the representative of the group manually confirms and inputs the number of users via the destination operating panel, then the system can accurately register group size, but the operation becomes burdensome and convenience deteriorates
Solution Approach 1:
The system automatically detects and registers the number of users in the group by monitoring boarding actions, eliminating the need for manual input by the representative. The system serves itself by observing user behavior (boarding the elevator) and automatically recording the group size based on detected boarding patterns.
Solution Approach 2:
The manual mechanical process of counting and inputting user numbers is replaced by an automatic detection system using sensors and control logic that monitor elevator car load changes and boarding events to determine group size automatically.
2Quantity of substance
If a large value is inputted as the number of users, then the system can accommodate large groups, but users must wait in the hall until a vacancy occurs and operation efficiency deteriorates
Solution Approach 1:
The system pre-registers group boarding requests and proactively monitors elevator car vacancies in advance. When a vacancy becomes available, the system immediately assigns and notifies the group, rather than waiting passively. This preliminary monitoring and proactive assignment reduces waiting time and improves operational efficiency.
Solution Approach 2:
The system continuously monitors the status of elevator cars (occupancy, location, availability) and uses this real-time feedback information to dynamically assign groups to appropriate cars. The feedback loop enables the system to respond quickly to changing conditions and optimize group assignment for efficiency.
3Productivity
If the system waits for a vacancy to occur in an assigned car before notifying users, then car assignment can be optimized, but waiting time increases and convenience deteriorates
Solution Approach 1:
The system continuously monitors elevator car status and maintains an updated view of available capacity and car locations. This continuous monitoring allows the system to immediately detect and respond to vacancies, eliminating idle waiting time and maintaining optimal assignment conditions at all times.
Solution Approach 2:
The car assignment is made dynamic and flexible rather than static. The system can reassign groups to different cars based on real-time conditions, and can notify groups of multiple potential assignment options. This dynamic approach allows the system to adapt quickly to changing elevator status and minimize waiting time while maintaining optimization.

AI summary
Provided is an elevator group control system which is excellent in convenience and can prevent a decrease in operation efficiency even when an elevator is used by a group of a plurality of persons. For this purpose, there are installed in an elevator hall a destination operating panel by use of which users register their destination floors before boarding and a group boarding registering device for registering that users use an elevator as a group. The number of users expected when users use an elevator as a group is stored beforehand in a user head-count storage section. When registration of a destination floor by use of the destination operating panel has been performed at the same time with registration of a group use by use of the group boarding registering device, a car to be assigned to a hall car call is determined on the basis of the number of users stored in the user head-count storage section.
