Method and system for conducting long-range control on intelligent terminal device

The invention discloses a method and system for conducting long-range control on an intelligent terminal device. The method comprises steps of A detecting a local area network and judging whether detected local area network information comprises target local area network information or not, on yes judgment, conducting a step B, and on no judgment, conducting a step C; B conducting login authentication according to the target local area network information, then sending device control information to the intelligent terminal device through the local area network to control the intelligent terminal device; and C detecting a wide area network, logging in the wide area network to be detected, and conducting authentication, and sending device control information to the intelligent terminal device through the wide area network to control the intelligent terminal device. By means of the method and system, long-range control efficiency can be improved, and long-range control cost is reduced.
