The invention discloses a graph
maintenance system and method for dispatching clouds. The
system comprises a security
proxy server, multiple dispatching clouds and multiple graph maintenance terminals; each dispatching cloud has a model service, a data service and a security control service; the graph maintenance terminals forward maintenance request or
library filling request information to the dispatching clouds corresponding to to-be-maintained graphs through the security
proxy server, and the dispatching clouds conduct user permission
verification through the security control services, conduct model
verification through the model services and return picture model data or
library filling operation result data to the graph maintenance terminals through the security
proxy server or returnerror information when
verification fails; and each graph maintenance terminal comprises a
graph drawing module, and the dispatching clouds provide
power equipment parameters and real-time state datafor the
graph drawing modules through the data services. According to the graph
maintenance system and method, most of the model data such as the graph
maintenance mode and pictures can be reused, therefore, the implementation cost of the dispatching clouds can be greatly reduced, and meanwhile the reliability and the practicability of graph maintenance can be improved.
