Detailed Description
The present application is further described with reference to the accompanying drawings and the detailed description, and it should be noted that, in the present application, the embodiments or technical features described below may be arbitrarily combined to form a new embodiment without conflict.
Referring to fig. 1, an embodiment of the present application provides a charging control method of an extracorporeal charger for charging a first stimulator implanted in a first patient, wherein a frequency and a resonant voltage of the extracorporeal charger may vary according to a relative position of the extracorporeal charger and the first stimulator.
The external charger can generate an alternating electric field, so that an induction coil in the stimulator implanted in human tissues can induce the alternating electric field to obtain energy, and a battery in the stimulator is charged; the charging habit of the user refers to the habitual wearing position of the external charger when the user charges, and in the prior art, after the charging process starts each time, the charging frequency and the resonance voltage of the external charger can be adaptively adjusted to adapt to the charging habits of different users.
The method comprises the steps S101-S103.
Step S101: recording final parameter values of charging parameters of a plurality of charging processes in which the external charger charges the first stimulator, wherein the charging parameters comprise one or more of frequency and resonant voltage of the external charger.
Step S102: and determining a recommended parameter value of the charging parameter corresponding to the first stimulator based on a final parameter value of the charging parameter in a plurality of charging processes of the first stimulator by the external charger.
Step S103: and controlling the external charger to charge the first stimulator according to the recommended parameter value of the charging parameter corresponding to the first stimulator, so as to improve the charging efficiency of the external charger for charging the first stimulator.
Therefore, the final parameter value of the charging parameter of the first stimulator in the multiple charging processes is recorded, the recommended parameter value is determined according to the recorded parameter, and then the external charger is controlled to charge the first stimulator by using the recommended parameter value of the charging parameter corresponding to the first stimulator, so that the charging parameter is automatically adjusted, and the charging efficiency of a user during charging reaches the optimal state.
In some embodiments, the step S101 may include: and recording the final parameter value of the charging parameter of the charging process in which the charging efficiency is greater than the preset charging efficiency in all charging processes of the first stimulator by the external charger.
The charging efficiency may be expressed as a percentage, for example, the charging power is 8W, the theoretical maximum value of the charging power is 10W, and the charging efficiency is 80%, or the charging efficiency may be directly expressed as the amount of electricity chargeable into the battery in a specific time period, for example, 20min may be full, and 5% per minute may be charged.
Therefore, the final parameter value of the charging parameter of the charging process with the charging efficiency higher than the preset charging efficiency is recorded, the parameter value lower than the preset charging efficiency is avoided being used as the recommended parameter value, the charging efficiency of the finally determined recommended parameter value is higher than the preset charging efficiency, and the charging efficiency when the recommended parameter value is used for charging is further ensured.
Referring to FIG. 2, in some embodiments, the step S101 may include steps S201 to S202.
Step S201: acquiring a final parameter value of a charging parameter of the latest N times of charging processes of the first stimulator by the in-vitro charger, wherein N is an integer greater than 1;
wherein, N may be a smaller value, for example, 5, and then the final parameter value of the charging parameter of the last 5 charging processes in which the external charger charges the first stimulator is obtained, or may be a larger value, for example, 50, and when the value of N is larger, the obtained final parameter value is more accurate.
Step S202: when the difference between the maximum value and the minimum value in the final parameter values of each charging parameter in the latest N times of charging process of the first stimulator by the external charger is not greater than the preset value corresponding to the charging parameter, recording the final parameter values of the charging parameters in the latest N times of charging process of the first stimulator by the external charger.
The preset value corresponding to the charging parameter may be a fixed value, for example, when the charging parameter is a resonant voltage, the preset value corresponding to the charging parameter may be 5V, or may be a floating value adjusted according to an initial use habit of a user, for example, when the user performs charging for the first time, the charging efficiency reaches the maximum efficiency, the preset value corresponding to the charging parameter may be adjusted to a lower value, for example, 1V, when the user performs charging for the first time, a difference between the charging efficiency and the maximum efficiency is large, for example, only 50% of the maximum efficiency is reached, and then the preset value corresponding to the charging parameter may be adjusted to a higher value, for example, 10V.
Therefore, the final parameter values of the charging process of the last N times are obtained, and when the full distance of the final parameter value of each charging parameter is not larger than a preset value, the final parameter values of the charging parameters of the last N times of charging process are recorded; a full-range condition is added for recording the final parameter value, the distribution range of the final parameter value of the charging parameter is limited, the interference of a value with a large individual difference on a final result is avoided, the recorded final parameter value can be closer to a real charging state, and the accuracy of the recommended parameter value is ensured.
The full pitch is a difference between a maximum value and a minimum value among final parameter values of each charging parameter, for example, when the charging parameter is a resonant voltage, the full pitch is 5V when the final parameter values of the plurality of charging parameters are 5V, 10V, 8V, and 7V, respectively.
