Working Principle：
Through PLC, various information of scene can be collected in real time, PLC regularly pack the collected data and sends it via Ethernet to the industrial PC equipped with CMS, CMS Control System can store, display, calculate and alert the transmitted data, so that users can remotely monitor the working state of crane, and the monitoring system is also connected with the database to store the alarm data, historical data and operation action information in the database so as to find fault.
In addition, monitoring system also has remote access function, it can visit all information of main frame via IE.
Application advantages：
1.The working process of spot can be reproduced and the working state can be monitored in real time.
2.It can record and store the historical data, alert data and operation data, and the data can be retrieved and filtered.
3.Animation display is more intuitive and eye-catching.
4.Centralized management of control can be realized and all-round supervision can be realized.
5.Remote monitoring of working process in spot can be realized.
