Real-Time Monitoring System Architecture
The comprehensive monitoring system consists of three distinct layers for optimal performance and reliability:
Device Layer
High-precision network recorders automatically capture temperature and humidity data, forwarding it to the monitoring software system through the network. Data integrity is maintained even during server downtime or network interruptions.
Control Layer
High-performance PC servers running ToMonitor software write serial server data into SQL databases in real-time. The system sends alarm notifications to administrators when readings exceed predetermined limits.
User Layer
Authorized users can access real-time monitoring and historical data through networked computers running ToClient software, with comprehensive alarm functionality for out-of-range conditions.
