Elevator Dispatching via Passenger Classification and Dynamic Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator systems fail to provide personalized services, are inefficient, and lack intelligence to identify safety risks or provide advanced experiences, especially for VIPs, resulting in a suboptimal passenger experience.
Innovation Solution
An elevator system with information collection devices in waiting areas and inside cars, combined with an information analysis and processing device that classifies passengers and dynamically transmits control commands to optimize dispatching, safety, and comfort, using sensors and smart terminals for data acquisition and face recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional unified scheduling is used for elevator dispatching, then standardized operation service is provided, but personalized services and VIP treatment cannot be provided
Solution Approach 1:
The passenger population is segmented into different categories (VIP, elderly, disabled, general passengers) based on collected information. The elevator system then provides differentiated services for each segment: VIP passengers receive priority dispatching and direct floor service, elderly and disabled passengers receive extended door open times and assistance, while general passengers follow standard procedures. This segmentation enables personalized service without requiring complete system redesign.
Solution Approach 2:
The system collects passenger information in advance (through mobile apps, RFID cards, or observation devices) and performs preliminary classification before the passenger actually needs service. This allows the elevator control system to pre-prepare personalized service parameters, such as pre-positioning the elevator car, pre-adjusting door timing, or pre-notifying floor attendants, thereby providing seamless personalized service without adding complexity to the real-time control logic.
2Adaptability or versatility
If more information collection devices are added to enable passenger classification and personalized service, then user experience is improved, but system complexity increases
Solution Approach 1:
The system employs multi-functional information collection devices that can perform multiple tasks: mobile phones serve both as communication devices and as carriers for RFID tags; cameras perform both security surveillance and passenger characteristic recognition; RFID readers handle both access control and passenger identification. This multi-functionality reduces the total number of separate devices needed and simplifies the overall system architecture while still enabling comprehensive passenger classification.
Solution Approach 2:
The system leverages information that passengers already carry or generate themselves, such as mobile phone identifiers, RFID cards, or voluntarily provided travel preferences. Passengers essentially provide their own classification data through their existing devices, and the system processes this information automatically. This self-service approach minimizes the need for additional dedicated collection devices and reduces system complexity.
3Productivity
If real-time passenger information is collected and processed, then operating efficiency is improved and safety risks are identified, but system complexity and processing requirements increase
Solution Approach 1:
The system implements selective information processing rather than analyzing all possible data points for every passenger. It focuses on collecting and processing only the most critical parameters needed for safety and efficiency: passenger count, weight distribution, presence of elderly or disabled passengers, and VIP status. By processing only these essential parameters in real-time while storing more detailed information for later analysis, the system achieves improved operating efficiency without overwhelming processing requirements.

AI summary
An elevator system comprises a first information collection device disposed in a passenger waiting area of the elevator system and used for acquiring first passenger characteristic information; a second information collection device used for acquiring second passenger characteristic information inside the car; an information analysis and processing device that receives the first passenger characteristic information and the second passenger characteristic information, is configured to perform analysis and processing, based on the first passenger characteristic information, so as to transmit a first control command for dispatching the elevator, is configured to perform analysis and processing on the first passenger characteristic information to acquire classification information of a passenger and to further transmit, based on the classification information, a second control command that is applicable for passengers in a corresponding classification, and is further configured to dynamically transmit, based on the second passenger characteristic information, a third control command.
