the micro control unit receives the indoor positioning information and the outdoor positioning information, and sends the indoor positioning information and the outdoor positioning information to a background server through an interface connected with the mobile terminal by the SIM module, so that the background server generates final positioning information according to the indoor positioning information and the outdoor positioning information.
6. The method according to claim 5, wherein: when positioning is needed, the method comprises the following steps:
an APP in the mobile terminal initiates a positioning request to the background server;
and the background server sends a positioning instruction to the micro control unit through an interface connected with the mobile terminal by the SIM module.
7. The method as recited in claim 6, further comprising:
and after the background server generates final positioning information according to the indoor positioning information and the outdoor positioning information, feeding back the final positioning information to the APP in the mobile terminal.
8. The method according to claim 5, wherein: the background server generates final positioning information according to the indoor positioning information and the outdoor positioning information, and the method comprises the following steps:
when at least one of the indoor positioning information and the outdoor positioning information is positioning information which is successfully positioned, positioning coordinates are obtained by calculating the positioning information which is successfully positioned through a preset positioning algorithm, and the positioning coordinates are used as final positioning information;
and when the indoor positioning information and the outdoor positioning information are positioning failure information, taking the positioning failure information as final positioning information.
