Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Based on the fact that the coupling performance of the existing TWS earphone and a charging box is extremely high, actions of the TWS earphone are generally controlled through the charging box, including key pairing, box opening and returning, box closing and disconnecting, master-slave switching and the like, and are controlled by a control signal sent by the charging box. Based on the above, the invention provides a wireless earphone charging control method, which avoids the situation that a charging box consumes the electric quantity of light at first, and ensures that the earphone can be used under any electric quantity. The following description will be given with reference to a specific embodiment.
The first embodiment of the present invention provides a method for controlling charging of a wireless headset, as shown in fig. 1, including the following steps:
a residual service time obtaining step, which is used for respectively obtaining the residual service time of each earphone and each charging box;
and a charging control step, comparing the remaining service time of each earphone with the remaining service time of the charging box, and controlling the charging of the earphones according to the comparison result. Current wireless headsets typically include two headsets, a left headset and a right headset.
In the wireless headset charging control method of the embodiment, only the headset with the remaining service time less than that of the charging box is charged by comparing the remaining service time of each headset with the remaining service time of the charging box, so that the condition that the electric quantity of the charging box is consumed first can be avoided, and the most basic service function of the headset is ensured no matter how much or little the remaining service time is. In addition, through the mode that adopts the surplus live time of each earphone of comparison and the box that charges in this scheme for the final surplus live time of each earphone and the box that charges is unanimous or close, and then the synchronous working duration of extension double earphone that can maximize promotes user's use and experiences.
In the charging control step, the step of determining the charging mode according to the remaining usage time of each earphone and the remaining usage time of the charging box is further included, and the corresponding charging mode is executed according to the determination result, as shown in fig. 2:
in the mode 1, when the remaining service time of the two earphones is less than the remaining service time of the charging box, the two earphones are charged; this scheme belongs to the condition that the remaining live time of two earphones all is less than the remaining live time of charging box, in order to guarantee the most basic service function of earphone, need to guarantee on the one hand that the earphone has the electricity, on the other hand charging box has the electricity, both lack one can, and the charging box is as the electric quantity supply end of earphone, when the earphone has the demand of charging and the remaining live time is not higher than the charging box, should satisfy the demand of charging of earphone, charge for it, prevent that another extreme condition from taking place, also the charging box has the electricity, the earphone does not have the electricity or the electric quantity is few, lead to unable earphone of use or the short problem of live time.
Mode 2, when the remaining usage time of one of the earphones is less than the remaining usage time of the charging box, that is, the remaining usage time of the other earphone is greater than the remaining usage time of the charging box, which indicates that there is a difference between the remaining usage times of the two earphones, if the earphone with the short remaining usage time is not charged in time, the earphone will first run out of power when in use, and cannot keep the two earphones to continue to work synchronously, furthermore, in order to reduce the power consumption of the charging box, the scheme charges the earphone with the remaining usage time less than the remaining usage time of the charging box, and as the charging continues, the power of the earphone with the original remaining usage time less increases, the remaining usage time is prolonged, and the remaining usage time of the charging box is shortened due to the power consumption, so that the difference between the earphones and the remaining usage time between the earphone and the charging box is reduced, and the remaining usage time is kept synchronous, the aim of prolonging the working time of each earphone and each charging box to the maximum extent can be achieved until the respective electric quantities are synchronously consumed.
And in the mode 3, when the residual use time of the two earphones is not less than that of the charging box, the two earphones are not charged. In order to ensure the most basic functions of the earphone, it is necessary to ensure that the earphone is charged on the one hand and the charging box is charged on the other hand, but both of the earphones and the charging box are not available, in this mode, because the remaining use time of the two earphones is not less than the remaining use time of the charging box, in order to prevent that the charging of the charging box may be exhausted first if the earphone is continuously charged, even if the earphone is charged, the earphone cannot normally work, and therefore the earphone is not charged temporarily. With the use of the earphone, the electric quantity is gradually consumed, the difference of the remaining use time between the earphone and the charging box can be shortened, and once the remaining use time of the earphone is less than the remaining use time of the charging box, the earphone can be charged.
When the remaining usage time of the two earphones is less than the remaining usage time of the charging box, if there is a difference in the remaining usage time between the two earphones, the working time lengths of the two earphones cannot be kept synchronized when the two earphones are charged synchronously, so the method 1 further includes a step of comparing the remaining usage time of the two earphones, including calculating a difference between the remaining usage time of the two earphones, and comparing the difference with a set value, as shown in fig. 3:
in the mode 1.1, when the remaining service time of the two earphones is less than the remaining service time of the charging box and the difference value of the remaining service time of the two earphones is less than a set value, the two earphones are charged at the same time; the mode shows that the residual use time of the two earphones is consistent or close, and the working time lengths are synchronous, so that the synchronous charging can prolong the residual use time of the two earphones synchronously.
And in the mode 1.2, when the remaining use time of the two earphones is less than the remaining use time of the charging box and the difference value of the remaining use time of the two earphones is not less than the set value, the earphones with less remaining use time are charged firstly. The condition of the mode is that the two earphones meet the condition of charging when judged according to the initial judgment condition, but the difference value of the remaining service time of the two earphones exceeds the set value through further judgment, namely the difference value of the remaining service time of the two earphones is larger, if the two earphones are synchronously charged, the remaining service time of the two earphones is synchronously prolonged, but the difference value of the remaining service time of the two earphones cannot be shortened, and the maximum time length for which the two earphones can synchronously work is based on the condition that the remaining service time is short. Therefore, the scheme firstly charges the earphones with less residual service time, in the charging process, the residual service time of the earphones is gradually increased, the residual service time of the charging box is gradually reduced, and the residual service time of the earphones which are not charged is not changed, so that the difference of the residual service time between the two earphones and between the earphones and the charging box can be gradually shortened.
In the charging process, the remaining use time of the charged earphones and the charging box is dynamically changed, so that the size relationship between the three is possibly changed, in order to adapt to the change of the remaining use time of each earphone and the charging box, so that the charging scheme can be timely adjusted, and the earphones can reach the maximum use time, in the charging control step, a polling function is started, the remaining use time of the two earphones and the remaining use time of the charging box are periodically detected, the charging mode judgment step is returned according to the newly detected remaining use time of the two earphones and the remaining use time of the charging box, and the corresponding charging mode is executed according to the judgment result.
Specifically, the following situations may occur in the polling process in each charging mode:
mode 1.1, in which the initial remaining usage times T1 and T2 of the two earphones are close, can be simplified to T1= T2, and the remaining usage time T3 > T1= T2 of the charging box, and the charging can therefore be synchronized to extend the remaining usage times of the two earphones, and at the same time, the remaining usage time T3 of the charging box is reduced, and when it is detected that the remaining usage times T1, T2 of the earphones are no longer less than the remaining usage time T3 of the charging box, the charging of the earphones is stopped, and the earphone power of the charging box is prevented from being excessively consumed. At the moment, the earphone can be normally used, the power consumption is eliminated in the using process, when the user puts the earphone into the charging box again, the remaining service life of the earphone is smaller than that of the charging box again, and then the charging box can be continuously charged according to the mode 1.1, so that the balance of the remaining service life of the earphone and the charging box can be kept, the basic working function of the earphone is guaranteed, and the working time of the earphone can be prolonged to the maximum extent.
In the mode 1.2, the difference between the remaining usage time of the two earphones is large in the mode, for example, T1-T2 > a, a can be 0 or a positive number, and the earphones with less remaining usage time (T2) are charged first. The following situations may occur during charging: (1) when the remaining use time T3 of the charging box itself is insufficient, the remaining use time T2 of the charged headphones gradually increases, the remaining use time T3 of the charging box gradually decreases, and when T1 > T3 > T2 occurs, the mode 2 is assumed, and the charging control is performed according to the mode 2. (2) The remaining use time T3 of the charging box itself is sufficient, the remaining use time T2 of the charged headphones gradually increases, the remaining use time T3 of the charging box gradually decreases, and when T3 > T1= T2 occurs, which is the case of the mode 1.1, the charging control is performed according to the mode 1.1.
Mode 2, symbolically represented by T1 > T3 > T2, charges only the headset with time of use T2 remaining until T2 is not less than T3, stops charging the headset, and the headset with time of use T1 remains uncharged.
Mode 3, symbolically represented by T1 > T3, T2 > T3, neither headset is charged.
Because the battery capacity of the charging box is large, the remaining use time of the charging box when the charging box is fully charged is larger than the remaining use time of the earphone when the earphone is fully charged and is several times of the remaining use time of the earphone, the remaining use time of the earphone is still smaller than the remaining use time of the charging box after the earphone is fully charged in the charging process, and if the charging is stopped in time, the charging box can continue to be charged, so that the electric energy is wasted. Therefore, in the polling process, when the remaining use time of any earphone is less than the remaining use time of the charging box, and the remaining use time reaches the longest use time or whether the remaining capacity is full, the charging of the earphone is stopped, wherein the longest use time is the use time corresponding to the remaining capacity of the earphone when the remaining capacity is full.
Similarly, in the charging control step, before the charging mode determining step, the method further includes a step of determining whether the remaining usage time of the earphone is the longest usage time or determining whether the remaining capacity of the earphone is full, and when the remaining usage time of the earphone is the longest usage time or the remaining capacity of the earphone is full, the earphone is not charged.
When a user puts the earphones into the charging box, the charging box respectively acquires the electric quantity information of the two earphones through the communication interface, and the using time is calculated according to the power consumption test result, wherein the preferable method for acquiring the remaining using time in the embodiment is as follows:
respectively detecting the residual electric quantity of each earphone and each charging box; the remaining capacity can be directly detected by the voltage detection circuit.
Calculating the remaining usage time: the remaining usage time of each earphone and charging box is equal to the remaining capacity of the earphone or charging box divided by its power consumption. The master-slave relation of each earphone is correspondingly determined once the power consumption is determined, and the power consumption of the charging box can be determined, and the power consumption is different, in the scheme, the electric quantity in the charging box is effectively utilized by comparing the remaining service time of each earphone and the remaining service time of the charging box, so that the earphone charging box is optimally distributed among the two earphones and the charging box, the situation that only one or two earphones are powered but the earphones cannot be used are effectively avoided, and the longer endurance is realized.
When two earphones are not charged, each earphone and the charging box are controlled to enter a low power consumption mode, and unnecessary consumption of electric quantity is prevented. Specifically, entering the low power consumption mode refers to turning off some functional circuits, such as the rf communication circuit, stopping transmitting and receiving the rf signal, and only retaining the basic detection function of detecting the opening of the charging box and the wake-up function of the control module.
In a second embodiment, the present invention further provides a wireless headset charging device, which has a charging box, a battery and a control module for controlling key pairing, box opening and returning, box closing and disconnecting, master-slave switching, and the like, and can control charging of a headset placed therein when conditions are met, wherein the wireless headset charging device includes the wireless headset charging control method described in the first embodiment. For a specific method for controlling charging of a wireless headset, reference may be made to the first embodiment, which is not described herein.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art may make modifications, alterations, additions or substitutions within the spirit and scope of the present invention.
