Sign-in method and system based on indoor positioning technology

Disclosed is a sign-in method based on an indoor positioning technology, comprising: when a user equipment is within a base station signal coverage range of an indoor positioning base station, measuring a distance value between the user equipment and the indoor positioning base station via a Beacon technology and sending the distance value to the indoor positioning base station; receiving, by the indoor positioning base station, device information and the distance value, and sending the device information and the distance value to an identification server; judging, by the identification server, whether the user equipment has been registered according to the device information; judging, by the identification server, whether the distance value satisfies a pre-set condition if it is judged that the user equipment has been registered, and determining that the user equipment has successfully signed in if so; and taking, by the identification server, current time as sign-in time of the user equipment, and recording the sign-in time. Also disclosed is a sign-in system based on an indoor positioning technology. The present invention can achieve identity identification via an indoor positioning technology, and achieve automatic signing in and signing off according to a distance value between a user equipment and an indoor positioning base station.
