detailed description

[0036] The most critical idea of the present invention is: by comparing the magnetic flux received by the smart shoe in the charging state with the magnetic flux received by the preset smart shoe at the optimal charging position, it can be determined whether the current smart shoe is at the most Good charging position, if not in the best charging position, send a reset to the user's mobile terminal Tips for smart shoes to ensure that the smart shoes are in an efficient state of charge.

 [0037] As shown in FIG. 1 , the present invention provides a wireless charging method for a smart shoe, including:

 [0038] the smart shoe sends a handshake signal to the first terminal;

 [0039] the first terminal establishes a charging connection with the smart shoe according to the handshake signal;

 [0040] calculating a magnetic flux received by the smart shoe;

 [0041] when the magnetic flux is less than the preset first magnetic flux 吋, sending a prompt message for resetting the smart shoe to the second terminal

[0042] Preferably, the method for establishing a charging connection is specifically:

 [0043] placing the smart shoe to be charged in the charging area of the first terminal, and the smart shoe sends a handshake signal to the first terminal

[0044] After the first terminal receives the handshake signal, the first terminal forms a closed loop, and the transmitting magnetic flux wirelessly charges the smart shoe.

 [0045] Preferably, the method for calculating the magnetic flux received by the smart shoe is specifically: after the charging connection between the smart shoe and the second terminal is successfully established, the second terminal sends the feedback information of the successful connection to the smart shoe; After the shoe receives the feedback information of the connection success, the magnetic flux is calculated by a flux meter built in the smart shoe; the flux meter includes a measuring coil and a circuit for estimating the voltage change on the measuring coil. If the magnetic flux received by the smart shoe is 95%-100% of the magnetic flux emitted by the first terminal, a green flashing signal is emitted through the LED light on the first terminal, indicating normal charging; if the magnetic flux received by the smart shoe is less than the first 95% of the magnetic flux emitted by the terminal sends a prompt message for resetting the smart shoe to the second terminal, and emits a red warning light through the LED light on the first terminal.

 [0046] Further, the method further includes:

 [0047] obtaining a battery state of the smart shoe;

 [0048] when the battery state is in a saturated state, sending information to the first terminal to stop charging;

[0049] The first terminal is disconnected from the charging connection of the smart shoe.

 [0050] As can be seen from the above description, when the battery state of the smart shoe is in a saturated state, by charging the first terminal to stop charging, thereby triggering the first terminal to disconnect the charging connection with the smart shoe, the charging security can be ensured.

[0051] Further, the method further includes: [0052] obtaining a battery state of the smart shoe;

 [0054] the third terminal sends prompt information of charging completion to the second terminal;

 [0055] obtaining a preset number of times of charging the smart shoes, and obtaining a historical charging length;

 [0056] calculating an average value of the preset charging time length of the preset number of times to obtain an average historical charging length;

 [0057] When the difference between the current charging length and the average historical charging length is greater than a preset charging time difference threshold, the third terminal sends the prompt information of the maintenance device to the second terminal.

 [0058] According to the above description, the third terminal compares the current charging length with the historical average charging length, analyzes the loss of the energy-consuming equipment in the smart shoe, and sends the loss to the mobile terminal of the user of the smart shoe. Maintaining the prompt information of the energy-consuming equipment ensures that the smart shoes can work normally in the long run; Since the abnormal charging data may be an unexpected situation at one time, it is more common to use the average data of the historical charging data to analyze the loss of the energy-consuming equipment. Sex, if the long-term charge of this charge is greater than the average number of historical charge lengths (for example, M=0.5h or lh), it is very likely that there is a problem with the energy-consuming equipment or other equipment, and it needs to be related to maintenance or replacement. device.

 [0059] Further, the method further includes:

 [0060] when the magnetic flux is greater than the preset second magnetic flux 吋, sending the prompt information for stopping charging to the first terminal; [0061] the first terminal is disconnected from the charging connection of the smart shoe.

 [0062] It can be seen from the above description that when the magnetic flux is greater than the preset second magnetic flux 吋, it is determined that the smart shoe is in an abnormal charging state; the second magnetic flux is the maximum magnetic flux that the smart shoe can bear; when the smart shoe is in abnormal charging The status 吋 sends a prompt message for stopping charging to the first terminal, thereby triggering the first terminal to disconnect the charging connection with the smart shoe, and stopping the power supply to the smart shoe, thereby ensuring the charging safety of the smart shoe.
