when the current positioning data of the wrist wearing equipment exceeds the daily activity range of the wrist wearing equipment, an alarm signal is sent to the user side.
7. A system for positioning through a wrist-worn device, comprising:
the wrist wearing device comprises a cloud server and a plurality of wrist wearing devices;
the cloud server and the user side are in communication connection in advance;
the cloud server is used for receiving a positioning request sent by a user side, wherein the positioning request comprises information of wrist wearable equipment needing to be positioned, and the wrist wearable equipment needing to be positioned is determined according to the positioning request;
establishing communication connection with the wrist wearable device needing positioning, sending a first positioning signal to the wrist wearable device, controlling the wrist wearable device to enter a first positioning mode, and receiving current positioning data sent by the wrist wearable device in the first positioning mode;
if the current positioning data sent by the wrist wearing equipment in the first positioning mode cannot be received within the preset time, sending a second positioning signal to the wrist wearing equipment, controlling the wrist wearing equipment to enter a second positioning mode, and receiving the current positioning data sent by the wrist wearing equipment in the second positioning mode;
if the current positioning data sent by the wrist wearing equipment in the second positioning mode cannot be received within the preset time, alternately sending the first positioning signal and the second positioning signal to the wrist wearing equipment by taking the preset time as an interval;
sending the current positioning data to the user side;
the wrist wearable device is used for entering a first positioning mode when receiving the first positioning signal, acquiring current positioning data and sending the current positioning data to the cloud server; entering a second positioning mode when the second positioning signal is received, acquiring current positioning data, and sending the current positioning data to the cloud server;
if the positioning request further comprises a Bluetooth positioning request, the cloud server further sends a fourth positioning signal to the wrist wearable device and receives a Bluetooth broadcast ID sent by the wrist wearable device; the Bluetooth broadcast ID is acquired from Bluetooth equipment in a preset range by calling mesh networking through the wrist wearable equipment through broadcast scanning; determining geographical position information of the Bluetooth equipment according to the Bluetooth broadcast ID, and sending the geographical position information of the Bluetooth equipment to the user side as Bluetooth positioning data;
the cloud server also acquires card swiping data generated when the wrist wearable device performs data interaction with a pre-established card swiping device through radio frequency identification; and determining the geographic position information of the card reader according to the card swiping data, and sending the geographic position information of the card reader and the time for acquiring the card swiping data to the user side.
