Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for monitoring the number of persons entering and exiting facilities lack efficient data collection and statistical processing capabilities, especially for multiple locations, leading to difficulties in remote data management and user data presentation.
Innovation Solution
A facility operation assistance system comprising image capture devices and a server device connected via a network, where the image capture devices detect and count individuals entering and exiting, generating measurement data that is transmitted and statistically processed by the server for timely and efficient data presentation to users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple image capture devices are installed in facilities to monitor entry/exit persons, then measurement data collection capability is improved, but device complexity and labor for setting up increases
Solution Approach 1:
The patent merges the functions of multiple image capture devices by having them all transmit data to a single server device for centralized processing. This consolidates what would otherwise be multiple independent systems into one coordinated network, reducing overall system complexity while maintaining the ability to monitor multiple facilities.
Solution Approach 2:
The server device acts as an intermediary between the image capture devices and the user. Instead of each device needing to process and display data independently, they all communicate through the server, which handles data collection, storage, and presentation. This intermediary layer simplifies the architecture by centralizing functionality.
2Loss of information
If image capture devices transmit measurement data continuously to server, then data availability is improved, but network bandwidth consumption and transmission conflicts increase
Solution Approach 1:
The patent implements periodic action by having image capture devices transmit measurement data at predetermined time intervals rather than continuously. The server requests data at specific periods, and devices transmit then, creating a rhythmic rather than continuous communication pattern. This reduces network bandwidth consumption while maintaining data availability through regular updates.
3Productivity
If statistical processing is performed at each image capture device, then processing speed is improved, but device complexity and data standardization difficulty increase
Solution Approach 1:
The patent extracts the statistical processing function from individual image capture devices and consolidates it at the server device. Instead of each device performing complex analysis locally, they simply collect and transmit raw data, while the server performs the statistical processing. This extraction simplifies the devices while centralizing intelligence where it's most needed.
Solution Approach 2:
The server device provides universal statistical processing capability that can handle data from multiple different image capture devices. Rather than requiring each device to have specialized processing for its specific location, the server's multi-functional processing can adapt to various facilities, standardizing data across the network while maintaining flexibility.
4Loss of time
If real-time data transmission is implemented for statistical processing, then data timeliness is improved, but network congestion and transmission errors increase
Solution Approach 1:
The patent uses periodic action to balance timeliness and reliability by transmitting data at predetermined intervals rather than continuously. This rhythmic transmission pattern prevents network congestion that would occur with constant data flow, while still providing timely updates. The server's periodic requests ensure data is fetched at appropriate moments without overwhelming the network.
Data Source
AI summary
A server collects measurement data of a camera to efficiently generate statistical data relating to the number of entering and exiting persons, and present the data to a user. The camera includes image capture unit capturing an image of a doorway of a facility, processor detecting persons entering and exiting from the doorway based on captured images sequentially output from the image capture unit and generating measurement data relating to the number of entering and exiting persons for each predetermined period, and communication unit transmitting the measurement data output from the processor for each predetermined period to store server, and store server includes communication unit receiving measurement data for each predetermined period transmitted from camera, storage unit accumulating measurement data for each predetermined period received by the communication unit, and processor statistically processing measurement data for each predetermined period to generate statistical data for targeting one or more facilities.
