Utility model content

The purpose of this utility model is to provide a kind of anti-lost follow-up mechanism, and being intended to solve the existing corresponding product with anti-lost tracking function, can not to meet usable range limited simultaneously, little power consumption, and the problem that use cost is low.

A kind of anti-lost follow-up mechanism is provided, comprise gsm module, WIFI module, bluetooth module, GPS module, MCU module, power management module and battery, described gsm module, WIFI module, bluetooth module, GPS module is connected with described MCU module all respectively, described power management module is connected with described bluetooth module, described battery by described power management module for above-mentioned all modules provide voltage to input, during operation, whether detect the mobile terminal bluetooth module signal of pairing lower than the first preset signal strength, if, carry out over range first time to report to the police, carry out the timing of warning duration, if when warning duration is more than the first duration, by described bluetooth module opening power administration module, WIFI module and GPS module, the locating information broadcast described GPS module obtained by the service set of described WIFI module, when described warning duration is more than the second duration, carries out over range second time and report to the police, open gsm module by described MCU module, by described gsm module, described locating information is sent to described mobile terminal or server.

Further, described anti-lost tracker is also for when described GPS module can not be located, described WIFI module is scanned the physical address of surrounding environment wireless network access point (WIFI Access point, WIFI AP) by described gsm module passback server.

Further, described gsm module comprises any one of 2G, 3G or 4G.

Further, also comprise SPI Inner to deposit and gravity sensor, described SPI Inner deposits and is connected with bluetooth module with gravity sensor, SPI Inner deposits the locating information and motion track information that obtain for GPS module described in buffer memory, and whether gravity sensor is used for obtaining anti-lost follow-up mechanism and moves and the frequency of movement.

The utility model embodiment, the first stage, by detecting whether within the effective join domain of Bluetooth signal, if not, carries out the warning of article over range; Subordinate phase, if report to the police the coordinate do not removed opening the acquisition of WIFI module broadcast GPS module through after a period of time; Again through still not recovering article after a while, carrying out second time and reporting to the police, unlatching gsm module being passed back article position coordinate, the present invention, achieving GPS, GSM, WIFI tri-mould, anti-lost tracking with low power.
