Monitoring information master station verification method and system

The invention discloses a monitoring information master station verification method and system. The method comprises the following steps: constructing a monitoring information master station verification system; monitoring information is expanded to check an automatic closed-loop joint debugging request message, and establishment and termination of an automatic closed-loop joint debugging function between a dispatching master station and a transformer substation integrated automation system are achieved; dividing a signal flow in a monitoring information master station verification system into an uplink signal and a downlink signal; and the expansion monitoring information checks the automatic closed-loop joint debugging data message. In order to ensure the accuracy and timeliness of signal automatic checking work, a full-closed-loop scheme is adopted, and full-closed-loop transmission of signals from a station-end automatic acceptance system to a telecontrol machine to a master station and finally back to th
