The invention discloses a safe region-crossing equipment uniform monitoring method based on independent monitoring services, and a monitoring system for the same, which are used for safe region-crossing equipment comprehensive monitoring of a power dispatching automation system. The monitoring services are independently arranged and run in different safe regions, a global unique production mechanism of the instance identifiers of resource, warning and performance models is used, timely collection of the safe region-crossing equipment resource, warning and performance information in a safe III region monitoring service is realized, and a III region monitoring client monitors and manages the equipment uniformly. With the method, the independently arranged monitoring services have basic capabilities in resource model management, equipment warning basic analysis and management, and performance data processing, thus, data redundant transmission through a physical isolation device is reduced, some of the pressure on the III region uniform monitoring service is shared, and finally, the safe region-crossing equipment uniform monitoring is finished.
