Secondly, because the SCADA is used as the data acquisition layer 12, the SCADA is located in a remote monitoring room and is far away from the field devices of the factory, when the network is disconnected or is interfered, the real-time data of the site cannot be collected by the SCADA, so that the field data is lost, and the intelligent analysis and the historical data analysis of the system on the real-time running condition of the field devices are influenced.
In addition, the number, model, and communication protocol of the field devices 111 in the field device layer 11 may change at any time, and the SCADA needs to be reconfigured, so that the change of the number of the field devices cannot be automatically adapted without affecting the operation of the original system.
Therefore, it is desirable to develop a data management and transmission system for intelligently managing and analyzing the real-time data of the field devices, which overcomes the above-mentioned drawbacks.
