Centralized Sensor Control via Web Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for sensor monitoring and data acquisition lack integrated control, analysis, and network communication capabilities, with separate components for web servers, control units, and analysis, limiting remote control and data storage of analog and digital sensors.
Innovation Solution
A centralized system with a local central processor, employing a Keil RTX operating system, integrated with a web browser for data transmission, and capable of controlling multiple sensors and instruments via wired, radio, or other data transmission methods, allowing real-time data streaming and storage, and enabling remote monitoring and control over a network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If separate components are used for web server, control unit, and analysis, then system modularity is improved, but integrated control capability deteriorates
Solution Approach 1:
The patent merges the web server, control unit, and analysis functions into a single centralized system. The web server receives requests, the control unit processes sensor data, and analysis is performed all within one integrated platform, eliminating the need for separate components while maintaining full control capability.
Solution Approach 2:
The centralized system performs multiple functions including web serving, sensor control, data analysis, and remote monitoring through a single unified platform. This multi-functional approach allows one system to replace what would traditionally require multiple separate components.
2Ease of operation
If remote control via network is implemented, then accessibility is improved, but system complexity deteriorates
Solution Approach 1:
The web server acts as an intermediary between remote users and the control system. It receives HTTP requests from remote clients, translates them into control commands, and manages communication protocols, thereby simplifying the interface between remote users and the complex underlying control architecture.
3Loss of information
If data is stored locally in sensors, then data availability is improved, but centralized data management deteriorates
Solution Approach 1:
The system implements feedback mechanisms where sensors store data locally and periodically transmit it to the centralized control unit. The control unit receives, processes, and manages this data, creating a feedback loop that ensures both local data availability and centralized management without requiring constant network connectivity.
