Virtual terminal automatic connection method and device in secondary system

The invention discloses a virtual terminal automatic connection method and device in a secondary system. The method and the device are used for solving the problems that the manual virtual terminal connection efficiency is low, and connection errors easily occur. The method comprises the following steps that first general equipment corresponding to first practical equipment is determined, second general equipment with the connection relationship with the first general equipment is determined on the basis of a rule base, and in addition, description information of the first general equipment and the second general equipment is obtained; the middle conclusion of the virtual terminal connection is determined according to the description information of the first general equipment, the description information of the second general equipment and the rules in the base rule, and the virtual terminal connection relationship of the first general equipment and the second general equipment is determined according to the middle conclusion and the rule reasoning in the rule base; second practical equipment corresponding to the second general equipment is determined, and the first practical equipment and the second practical equipment are subjected to virtual terminal connection according to the virtual terminal connection relationship of the first general equipment and the second general equipment. The virtual terminal automatic connection can be realized by adopting the method.
