Very long distance supervisory control and data acquisition system
Yongming Wang · Journal of Jilin University of Technology · 2004
The idea of very long distance supervisory control and data acquisition system (VLD-SCADA) was presented with its analyzed functionality and characteristics. A GSM short message system based on VLD-SCADA design was given focusing on system architecture, data transfer protocol and application command protocol. Frame definition, receive-transition and problem processing scheme, supervision set and opened embedded script extension capability were discussed. The proposed solution was implemented in a VLD-SCADA system with several hundred kilometers.
