RJ45 Real Time Monitor System Network Topology Map

The monitoring system consists of device layer, control layer and user layer.

User layer: including User Company any internal networking computer, install the ToClient client software, you can view the current real-time running state or historical data. Working principle: all data are stored in the control layer (control server) database, the user can only through the local area network (or Internet) to query the historical data or view real-time data. ToClient client software to receive the server sent over the real-time data, it will be judged, if the temperature and humidity data over the set of the upper and lower limits, ToClient software will play alarm sound. The user can query the system according to the authority.

Control layer: high performance PC server running ToMonitor monitoring software, the serial server report data written into the SQL database in real time. For more than a predetermined set of upper and lower limits of the recorder, send the appropriate alarm information to the administrator.

Equipment layer: all high precision network recorder can automatically record the temperature and humidity data, and forwarded to the ToMonitor software system through the network. Even if the server is not started or the line is broken, the recorder can record the data automatically, and the data loss will not occur.

• Service ToMonitor software

1. ToMonitor is the server software can receive the data uploaded recorder and displayed on the interface of the software, you can set the temperature and humidity range of each device in the ToMonitor, once the temperature or the humidity value exceeds the set range, the system will give an alarm.

2. ToMonitor is the server software can receive the data uploaded recorder and displayed on the interface of the software, you can set the temperature and humidity range of each device in the ToMonitor, once the temperature or the humidity value exceeds the set range, the system will give an alarm.

3. The system supports RJ45, GPRS, RS485, USB and other relay hybrid access, can be very strong.

4. ToMonitor system supports multi-threaded processing, make full use of multi-core CPU performance, increase the throughput of the system. Send the alarm, the system will not affect the data received.
