Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction machine monitoring systems face challenges in securely transmitting and authenticating video data from construction machines to external devices, particularly due to the inclusion of sensitive information like operator faces and the need for physical contact during authentication, which complicates the handling and security of image data.
Innovation Solution
A monitoring system with a construction machine equipped with a first camera, video recording device, and wireless communication device allows video transmission to a portable monitoring device, featuring separate authentication displays inside and outside the cab for identification and password entry, ensuring secure and convenient access to peripheral region videos.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple types of information (operator information, workpiece information, tool information, machine information) are collected and managed in a centralized server, then information management efficiency and productivity are improved, but system complexity and infrastructure requirements increase
Solution Approach 1:
The system divides information management into two segments: a centralized server for comprehensive data storage and processing, and edge terminals (construction machines, mobile devices) for local data collection and preliminary processing. This segmentation allows efficient centralized management while distributing system functions to reduce single-point complexity.
Solution Approach 2:
The server acts as an intermediary that receives, stores, and processes information from multiple sources (construction machines, mobile terminals, cloud services). This intermediary role centralizes information management functions, improving overall system efficiency while allowing individual components to remain relatively simple.
2Adaptability or versatility
If GPS reception is used to determine construction machine position, then positioning capability is provided, but positioning accuracy deteriorates in canyons or forest areas with poor GPS reception
Solution Approach 1:
The system merges multiple positioning methods: GPS satellite-based positioning for open areas, and inertial sensors (accelerometers, gyroscopes) for areas with poor GPS reception. By combining these methods, the system maintains positioning capability in diverse environments while improving accuracy where GPS alone fails.
Solution Approach 2:
The system dynamically changes positioning parameters by switching between GPS-based absolute positioning and inertial sensor-based relative positioning depending on signal availability. When GPS signal quality degrades, the system transitions to using acceleration and angular velocity data to calculate position changes, maintaining positioning functionality across varying environmental conditions.
3Quantity of substance
If construction machine position is recorded at regular time intervals, then position history is captured, but position information during intervals between recordings is lost
Solution Approach 1:
The system uses inertial sensors (accelerometers and gyroscopes) that continuously measure motion parameters between GPS recordings. By integrating acceleration data over time, the system calculates position changes occurring between discrete GPS data points, effectively capturing continuous position information without increasing GPS sampling frequency.
Solution Approach 2:
The inertial sensors continuously monitor and pre-calculate position changes between GPS recordings. This preliminary action of tracking motion parameters ensures that position information during intervals is captured through sensor data, which is then combined with periodic GPS data to reconstruct complete position history.
