Problems solved by technology

[0008] SCADA systems generally limit the number and access frequency of clients accessing the real-time library. Multiple clients at the application layer accessing the SCADA real-time library will cause too many real-time tasks in the SCADA system, seriously affecting the operating efficiency of the SCADA system.
[0009] Disadvantages of existing SCADA real-time data reading access: multiple clients repeatedly collect the same real-time data of SCADA; SCADA data access interface is complex; client access to SCADA data development workload is large; Open the SCADA access interface at the end, resulting in the data cannot be restricted according to the demand. The above phenomenon will increase the burden of data service provision, and the security of data application cannot be guaranteed.
[0010] For the above-mentioned problems existing in the prior art, no effective solution has been found yet
