Elevator Camera Image Transmission Reducing Network Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator monitoring systems increase network load due to the transmission of full image data from cameras to servers for analysis, which can lead to inefficiencies and increased processing loads.
Innovation Solution
A monitoring image transmission apparatus that selectively transmits images based on specific time points or periods, using an event input section, image management section, and image transmission section to send only relevant images to the image analysis server, reducing the amount of data transmitted and thus the network load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If full image data is transmitted from cameras to servers for analysis, then image analysis accuracy is improved, but network load increases
Solution Approach 1:
The patent extracts and transmits only specific portions of image data (e.g., regions containing events, specific time points, or selected frames) rather than complete continuous image streams. The image management section identifies and extracts relevant image segments based on event signals, time conditions, or analysis rules, thereby reducing the quantity of transmitted data while preserving essential information for accurate analysis.
Solution Approach 2:
The system transmits a partial set of image data that is sufficient for analysis purposes without transmitting the complete image stream. By applying selection criteria (event-based triggering, time-based sampling, or importance-based filtering), the system sends only the necessary portion of image data required for effective analysis, avoiding unnecessary data transmission.
2Reliability
If continuous image data is transmitted to the server, then monitoring coverage is improved, but processing load on the server increases
Solution Approach 1:
The image management section extracts and transmits only relevant image segments that contain meaningful information for monitoring purposes. By identifying key moments (event occurrences, time intervals, or significant changes) and extracting only those frames, the system maintains comprehensive monitoring coverage while significantly reducing the volume of data requiring server processing.
Solution Approach 2:
Instead of transmitting continuous uninterrupted image streams, the system transmits a selective subset of images that are sufficient for reliable monitoring. The transmission is triggered by specific conditions (events, time intervals, or detection algorithms) rather than continuous operation, reducing processing load while preserving monitoring effectiveness.
3Measurement precision
If all images are transmitted for analysis, then detection accuracy is improved, but transmission time increases
Solution Approach 1:
The system extracts and transmits only the most relevant images based on event signals, time-based criteria, or importance ranking. By identifying and extracting key frames that contain critical information for detection accuracy, the system reduces the total number of images transmitted while maintaining the essential data needed for accurate event detection and analysis.
Solution Approach 2:
The system transmits a carefully selected partial set of images that provides sufficient detection accuracy without the need to transmit every captured frame. By applying filtering and selection criteria (event-triggered transmission, time-sampling, or priority-based selection), the system achieves effective detection with reduced transmission time and data volume.
