Transmission method and transmission device for dynamic position information and terminal

The invention discloses a transmission method for dynamic position information. The transmission method comprises the following steps: when the current electric quantity of portable equipment lower than a preset electric quantity threshold is detected, acquiring wireless electromagnetic waves which are acquired by an antenna module and exist in a living space; receiving current position information acquired by a wireless positioning module, and encoding the current position information to obtain binary information; converting the wireless electromagnetic waves into electric energy, controlling a switch contact of the antenna module by using electric energy according to the binary information, so as to adjust a resistance value of the antenna, and enabling two state changes of the resistance value of the antenna to be consistent with the binary information; transmitting wireless electromagnetic waves by the antenna module with an adjusted resistance value of the antenna resistance. The invention also provides a transmission device for the dynamic position information and a terminal. By adopting the embodiment of the invention, the position information is transmitted by using existing wireless electromagnetic waves in the living space, so that electric quantity of the portable equipment can be reduced, and an effective transmission process of information of the portable equipment is prolonged to a great degree.
