Solution Overview

Problem

Current methods require a large number of fixed terminals to acquire human flow data over a wide area, making it difficult to gather data from remote locations effectively.

Innovation Solution

An information processing device and method that utilizes a mobile unit, such as a drone, to measure human flow data by setting a measurement area, controlling the unit to move within that area, and displaying the data in a heat map format, allowing for efficient data collection and visualization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a large number of fixed terminals are installed to acquire human flow data over a wide area, then data coverage area is improved, but device complexity and installation cost increase

Engineering Contradiction:
Improvedata coverage areaVSAvoidnumber of terminals required
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent transforms the static fixed terminal approach into a dynamic mobile unit system. The mobile unit (drone) moves dynamically across the measurement area, continuously changing its position to collect human flow data from multiple locations, thereby achieving wide area coverage with a single unit instead of multiple fixed terminals.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces three-dimensional aerial movement as a new dimension for data collection. Instead of deploying multiple terminals across the horizontal plane, a single mobile unit operates in the vertical dimension (air space), moving freely in three-dimensional space to cover the entire measurement area, thus reducing the number of required units.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If fixed terminals are used for human flow measurement, then measurement stability is improved, but mobility and accessibility to remote areas deteriorate

Engineering Contradiction:
Improvemeasurement stabilityVSAvoidmobility to remote locations
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system employs a mobile unit that can dynamically adjust its position and movement based on measurement requirements. The drone flies at controlled speeds and heights, maintaining stable measurement conditions while being able to reach remote areas that fixed terminals cannot access, thus achieving both stability and mobility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mobile unit acts as an intermediary between fixed infrastructure and remote measurement locations. It carries the measurement equipment and can operate independently without requiring physical installation at each measurement point, enabling access to remote areas while maintaining measurement capability through its mobile platform.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Area of stationary object

If multiple mobile units are deployed to cover wide areas, then data coverage is improved, but coordination complexity and motion vector correction requirements increase

Engineering Contradiction:
Improvedata coverage areaVSAvoidcoordination and control complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The system implements feedback mechanisms where each mobile unit reports its position, speed, and measurement data to a central control system. The control system processes this information and provides correction instructions for motion vectors, enabling coordinated operation of multiple units while maintaining measurement accuracy and avoiding data redundancy.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The measurement area is divided into multiple zones or sectors, with each mobile unit assigned to specific regions. This segmentation allows units to operate semi-independently in their designated areas, reducing coordination complexity while ensuring complete coverage when all units operate together. The system can dynamically reassign zones based on real-time conditions.

Inventive Principle:
Principle #1Segmentation

AI summary

A mobile unit control unit causes a communication unit to transmit user setting information supplied from an input unit and control data for controlling a mobile unit. A display control unit generates display data corresponding to the human flow data in a human flow data DB, and outputs the generated display data to a display unit. The communication unit transmits control data, measurement area information, and landing area information to the mobile unit, and receives human flow data from the mobile unit and supplies the human flow data to a control unit. The input unit sets setting information relating to human flow data measurement, in response to a user operation. The display unit performs display corresponding to the display data generated by the display control unit. The present disclosure can be applied to a human flow measurement system including a mobile unit and a terminal, for example.
