In one embodiment, when the base station sends the second message to the server, the base station may also send its own running time, and the server determines whether the base station is working normally according to its own running time sent by the base station, for example, when the base station sends the second message to the server twice, its own running time is the same, which indicates that the base station is not working normally.
In the above bracelet positioning method, when the base station sends the second message to the server, the base station can also send the running time of the base station, and the server judges whether the base station works normally according to the running time of the base station, so that the position of the bracelet can be recorded more accurately.
In one embodiment, as shown in fig. 7, the above bracelet positioning method further includes:
In step 702, a first application program of the terminal sends an instruction for configuring a first microwave communication identifier to the bracelet.
Step 704, the bracelet receiving terminal is a first microwave communication identifier configured for a bracelet.
In step 706, the bracelet broadcasts a first message carrying a first microwave communication identifier at a first preset time interval in a first microwave communication mode.
Step 708, after receiving the first message, the base station sends a second message to the server, where the second message carries the first microwave communication identifier, the base station identifier, and a time of receipt of the first message.
In step 710, when the base station does not receive the first message, the server sends the first microwave communication identifier of the bracelet and the target base station identifier to the handheld device.
Step 712, the handheld device searches for a corresponding bracelet at a location where the base station corresponding to the target base station identifier is located according to the first microwave communication identifier, where the target base station identifier is a base station identifier corresponding to the receiving time of the first message closest to the current time.
In step 714, the bracelet performs self-checking at a second preset time interval, and when the self-checking result is abnormal, the power is turned off and restarted.
Step 716, the bracelet obtains gravitational acceleration information or voltage information, determines motion state information according to the gravitational acceleration information, and determines electric quantity information according to the voltage information.
In step 718, the second application program of the terminal sends an instruction for acquiring the motion state information or the electric quantity information to the bracelet through the second microwave communication mode.
Step 720, after receiving the instruction for acquiring the motion state information or the electric quantity information, the bracelet correspondingly transmits the motion state information or the electric quantity information to the second application program of the terminal.
In step 722, the terminal sends the incoming call information to the bracelet in the second microwave communication mode.
Step 724, the bracelet controls the bracelet to send out reminding information according to the incoming call information.
According to the bracelet positioning method, the first message is broadcast by the bracelet, the base station sends the second message to the server according to the received first message, and the server generates the movement track of the bracelet corresponding to the first microwave communication identifier according to the geographic position corresponding to the first microwave communication identifier and the receiving moment of the first message, so that the geographic position of the bracelet can be accurately recorded. When the base station does not receive the first message, the mobile phone is used for receiving the first microwave communication identifier and the target base station identifier sent by the server, and searching for the corresponding bracelet according to the position of the base station corresponding to the target base station identifier and the first microwave communication identifier, so that the position of the bracelet can be recorded more quickly and accurately. In addition, the bracelet can be subjected to self-checking, so that the normal operation of the bracelet is ensured, and the geographic position of the bracelet can be recorded at any time and accurately. The first microwave communication identifier configured for the bracelet can be used for distinguishing different bracelets, so that the geographic positions of the different bracelets can be accurately recorded respectively. The bracelet can also send motion state information or electric quantity information to the terminal, and the motion state information can remind a bracelet wearer to develop good work and rest habits, and the electric quantity information can remind the bracelet wearer to charge the bracelet in time under the condition of insufficient electric quantity of the bracelet, so that normal operation of the bracelet is ensured. The hand ring receiving terminal sends the incoming call information and sends the reminding information, so that the user of the hand ring can be reminded of the incoming call information in time without checking the mobile phone at any time, and unnecessary time expenditure is saved.
It should be understood that, although the steps in the flowcharts of fig. 2 and 4-7 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders.
