The processor 31 is connected with the Bluetooth receiving module 32, the Bluetooth receiving module 32 is connected with the Bluetooth sending module of the mobile phone client 4 through Bluetooth connection or disconnection, and whether the child is in a safe distance or not is monitored in real time. The bluetooth receiving module 32 and the bluetooth sending module may have different transmission power levels, and the theoretical communication distance of the bluetooth receiving module 32 or the bluetooth sending module is determined by the transmission power levels. The existing bluetooth receiving module 32 and bluetooth transmitting module transmitting power graders are CLASS1 and CLASS2, wherein CLASS1 is 100 meters, and CLASS2 is 10 meters. Preferably, the bluetooth receiving module 32 or the bluetooth transmitting module selects the theoretical communication distance to be 10 meters, that is, when the theoretical communication distance is exceeded, the bluetooth is in the off state; when the theoretical communication distance is not exceeded, bluetooth is in a connected state.

When the Bluetooth receiving module and the Bluetooth sending module are in a Bluetooth connection state, the processor reads data output by the Bluetooth receiving module, the data output by the Bluetooth receiving module is at a high level, and the processor does not start the alarm module and the mobile phone client to alarm; when bluetooth receiving module and bluetooth sending module were in the bluetooth disconnection state, the data of bluetooth receiving module output were read to the treater, and at this moment, the data of bluetooth receiving module output were the low level, and the treater transmits the children geographical position and the alarm module alarm information of big dipper orientation module monitoring for mobile client, in time reminds parents children to have kept away from safe distance, seeks rapidly.
