As mentioned above, the active monitoring system of the serial monitoring device disclosed in the present invention may further include an integrated server 140. When the server 110 generates an OPC tag conforming to the published industrial communication standard, the integrated server 140 may be The OPC tag performs corresponding data exchange processing, for example, graphical monitoring. In actual implementation, the integrated server 140 is operated by a software (Supervisor Control And Data Acquisition, SCADA) with system monitoring and data acquisition function. The window 400 is graphically monitored. For example, after analyzing and processing the message according to the OPC label, the analysis processing result is displayed on the device display block 401, and even the switching device 390 can be switched to select the serial monitoring device 100, and respectively The remote monitoring of the selected serial monitoring device 100 is initiated, restarted, or turned off by the activation component 410, the reopening component 411, or the shutdown component 412. In addition, a report having at least one of text, image, and table may be generated from the OPC tag by clicking the report component 414.

In summary, it can be seen that the difference between the present invention and the prior art is that the serial data transmitted by the serial monitoring device 100 is received through the trigger terminal 120, and the serial data is analyzed to generate the device label, and then the device label is encapsulated.
