System and method for linkage of auxiliary monitoring system of transformer substation

The invention discloses a system and a method for linkage of an auxiliary monitoring system of a transformer substation, and the system comprises a linkage module which is used for obtaining the real-time alarm information of intelligent equipment of each subsystem of the auxiliary monitoring system of the transformer substation, issuing a control command based on a preset linkage rule, and generating linkage video alarm information; the alarm message bus module is used for acquiring the alarm information from the intelligent equipment and the linkage module and pushing the alarm information to the monitoring end; and the monitoring end displays the linkage video alarm information through a browser. The method comprises the following steps: formulating a linkage rule base according to a linkage relationship among linkage equipment; and acquiring a real-time alarm signal, judging whether a linkage triggering condition is met or not based on the linkage rule base, and executing a corresponding linkage action if
