Problems solved by technology

[0006] 1. The monitoring information focuses on the machining process of the machine tool, ignoring the monitoring of the field bus link of the CNC system
[0007] 2. When the CNC system completes real-time monitoring, it increases the burden of data processing of the CNC system
[0008] 3. The monitoring form and information of the CNC system are not easy to change, which will lead to incomplete real-time monitoring
[0009] 4. No remote real-time monitoring
